Coronavirus disease 2019 (COVID-19) was a more severe illness than seasonal influenza in hospitalised cohorts during the early phase of the pandemic. This study's aim was to determine if COVID-19 severity, relative to seasonal influenza, evolved across subsequent disease waves. Retrospective population-based cohort study. COVID-19 hospital episodes and seasonal influenza hospital episodes were identified using relevant International Classification of Disease (ICD-10) codes from the Irish national hospitalisation dataset. Descriptive comparative analysis of each group was carried out using Pearson's Chi-squared tests. Length of stay (LOS), intensive care unit (ICU) admission and in-hospital mortality were measured and compared using logistic regression analysis. Compared to influenza episodes, COVID-19 episodes for all ages and all waves combined, had a longer mean LOS (15.8 days, vs 11.4 days, P < 0.001); were more likely to receive ICU care (OR 1.24 95% CI 1.15–1.33, P < 0.001) and were more likely to die in hospital (OR 2.61, 95% CI 2.36-2-88). Despite the reduction in the proportion of patients with an intensive care unit (ICU) stay and dying in hospital in Wave 5 compared to the previous waves, the risk of having an ICU admission or dying in hospital remained higher in patients with COVID-19 in Wave 5 compared to those with influenza diagnosis. While the severity of COVID-19 has reduced with successive pandemic waves, it remains a more severe disease than influenza. Despite changes in strain, population immunity, vaccination and treatment, policymakers and the public must continue to approach COVID-19 as more than 'just a bad flu'. [ABSTRACT FROM AUTHOR]

Coronavirus disease 2019 (COVID-19) is known to increase the risk of venous thromboembolism (VTE) and arterial thromboembolism (ATE). However, the incidence, predictors, and outcomes of clinical thrombosis for inpatients with COVID-19 are not well known. This study aimed to enhance our understanding of clinical thrombosis in COVID-19, its associated factors, and mortality outcomes. Hospitalised adult (≥18 years of age) patients with COVID-19 in 2020 were retrospectively identified from the US National Inpatient Sample database. Clinical characteristics, incident VTE, ATE, and in-hospital mortality outcomes were recorded. Multivariable logistic regression was performed to identify clinical factors associated with thrombosis and in-hospital mortality in COVID-19 inpatients. A total of 1,583,135 adult patients with COVID-19 in the year 2020 were identified from the National Inpatient Sample database; patients with thrombosis were 41% females with a mean age of 65.4 (65.1–65.6) years. The incidence of thrombosis was 6.1% (97,185), including VTE at 4.8% (76,125), ATE at 3.0% (47,790), and the in-hospital mortality rate was 13.4% (212,785). Patients with thrombosis were more likely to have respiratory symptoms of COVID-19 (76.7% vs 75%, p<0.001) compared with patients without thrombosis. The main factors associated with overall thrombosis, VTE, and ATE were paralysis, ventilation, solid tumours without metastasis, metastatic cancer, and acute liver failure. Although all thrombosis categories were associated with higher in-hospital mortality for COVID-19 inpatients in univariable analyses (p<0.001), they were not in multivariable analyses—thrombosis (odds ratio [OR] 1.24; 95% confidence interval [CI] 0.90–1.70; p=0.19), VTE (OR 0.70; 95% CI 0.52–1.00; p=0.05), and ATE (OR 1.07; 95% CI 0.92–1.25; p=0.36). The association of COVID-19 with thrombosis and VTE increases with increasing severity of the COVID-19 disease. Risk stratification of thrombosis is crucial in COVID-19 patients to determine the necessity of thromboprophylaxis. [ABSTRACT FROM AUTHOR]

Acute pulmonary embolism (PE) is a significant cause of mortality in the hospital setting. The objective of this study was to outline the long-term outcomes after surgical and non-surgical management for patients with massive and submassive PE. Population cohort observational study evaluating all patients who presented to three tertiary hospitals in the state of Western Australia with access to cardiothoracic services over 5 years (2013–2018). Reviewed notes of all patients as well as radiology, linked mortality data and all available echocardiography studies at the primary hospital. In total, 245 patients were identified, of which 41 received surgical management and 204 non-surgical management; demographic data was similar. Clinically, the surgical group had higher rates of shock requiring vasopressors, severe bradycardia, or cardiopulmonary resuscitation prior to intervention. The 28-day mortality was not statistically significantly different between the surgical embolectomy group (2/41 [4.2%]) and the non-surgical group (17/201 [8.3%]) (p=0.382). There was no difference in 12-month mortality, including when this was adjusted for vasopressors, right ventricular (RV) strain, troponin, and brain natriuretic peptide. In the massive PE sub-group, 28-day mortality was not significantly different: 2/29 (6.9%) surgical group vs 7/34 (20.2%) non-surgical group (p=0.064). Higher rates of severe RV impairment and dilatation were present in the surgical group. All patients with available echocardiography studies at outpatient follow-up returned to normal or mild RV impairment. Patients who presented with massive or submassive PE had similar outcomes whether treated with surgical or non-surgical management. Surgical embolectomy is a safe option in a cardiothoracic centre setting. [ABSTRACT FROM AUTHOR]

• An improvement in mortality in sepsis patients with early administration of antibiotics at 3 and 6 hrs but not at 1hr. • Our findings do not support the current guideline recommendations to administer antibiotics to sepsis patients with shock within 1 hour of diagnosis. • Antibiotics should be administered within 3 hrs of sepsis recognition and/or ED arrival. To evaluate whether the timing of initial antibiotic administration in patients with sepsis in hospital affects mortality. This systematic review and meta-analysis included studies from inception up to 19 May 2022. Interventional and observational studies including adult human patients with suspected or confirmed sepsis and reported time of antibiotic administration with mortality were included. Data were extracted by two independent reviewers. Summary estimates were calculated by using random-effects model. The primary outcome was mortality. We included 42 studies comprising 190,896 patients with sepsis. Pooled data showed that the OR for patient mortality who received antibiotics ≤1 hr was 0.83 (95 %CI: 0.67 to 1.04) when compared with patients who received antibiotics >1hr. Significant reductions in the risk of death in patients with earlier antibiotic administration were observed in patients ≤3 hrs versus >3 hrs (OR: 0.80, 95 %CI: 0.68 to 0.94) and ≤6 hrs vs 6 hrs (OR: 0.57, 95 %CI: 0.39 to 0.82). Our findings show an improvement in mortality in sepsis patients with early administration of antibiotics at <3 and <6 hrs. Thus, these results suggest that antibiotics should be administered within 3 hrs of sepsis recognition or ED arrival regardless of the presence or absence of shock. [ABSTRACT FROM AUTHOR]

We sought to assess the impact of various perioperative factors on the risk of severe complications and post-surgical mortality using a novel maching learning technique. Data on patients undergoing resection for HCC were obtained from an international, multi-institutional database between 2000 and 2020. Gradient boosted trees were utilized to construct predictive models. Among 962 patients who underwent HCC resection, the incidence of severe postoperative complications was 12.7% (n = 122); in-hospital mortality was 2.9% (n = 28). Models that exclusively used preoperative data achieved AUC values of 0.89 (95%CI 0.85 to 0.92) and 0.90 (95%CI 0.84 to 0.96) to predict severe complications and mortality, respectively. Models that combined preoperative and postoperative data achieved AUC values of 0.93 (95%CI 0.91 to 0.96) and 0.92 (95%CI 0.86 to 0.97) for severe morbidity and mortality, respectively. The SHAP algorithm demonstrated that the factor most strongly predictive of severe morbidity and mortality was postoperative day 1 and 3 albumin-bilirubin (ALBI) scores. Incorporation of perioperative data including ALBI scores using ML techniques can help risk-stratify patients undergoing resection of HCC. [ABSTRACT FROM AUTHOR]

We aimed to assess the performance of common pneumonia severity scores, such as pneumonia severity index (PSI), CURB-65, CRB-65, A-DROP, and SMART-COP, in predicting adverse outcomes in elderly community-acquired pneumonia cohort and to determine the optimal scoring system for specific outcomes of interest. A total of 822 elderly inpatients were included in the retrospective cohort study. Clinical and laboratory results on admission were used to calculate the above scores. The primary outcome was 30-day mortality. Secondary outcomes were in-hospital mortality, need for mechanical ventilation (MV) and ICU admission. Model discrimination was evaluated by the area under receiver operating characteristic curves (AUCs). The 30-day and in-hospital mortality rates were 6.8% (56/822) and 8.6% (71/822), respectively. One hundred and ninety-eight (24.0%) received MV and 111 (13.5%) were admitted to the ICU. All five scoring systems showed the same trend of increasing rates of each adverse outcome with increasing risk groups (all p < 0.001). PSI had the highest AUC, sensitivity, and negative predictive value (NPV) in predicting 30-day mortality and in-hospital mortality. SMART-COP had the highest AUC for predicting the need for MV and ICU admission, but PSI had the highest sensitivity and NPV for these two outcomes. PSI performed well in identifying elderly patients at risk for 30-day mortality and its high NPV is helpful in excluding patients who are not at risk. Considering their effectiveness and simplicity, SMART-COP and CURB-65 are easier to perform in clinical practice than PSI. [ABSTRACT FROM AUTHOR]

Admission systolic blood pressure is a significant predictor of in-hospital mortality in patients with acute type A aortic dissection (ATAAD). While previous studies have focussed on recording the highest blood pressure value from both arms, this study aimed to evaluate the associations between blood pressure in bilateral arms and in-hospital mortality. Data were analysed from 262 patients with ATAAD treated at a single centre. The relationship between bilateral arm blood pressure upon admission and in-hospital mortality was assessed in a logistic regression model. To comprehensively evaluate potential non-linear relationships, the association between admission bilateral systolic blood pressure (SBP) and the risk of in-hospital mortality was analysed using restricted cubic splines on a continuous scale. Mean age was 53.6±12.5 years and 194 (74.0%) were male. Baseline and operative data showed that ages, body mass index, smoking, left-arm SBP, left-arm diastolic blood pressure (DBP), right-arm SBP, right-arm DBP, syncope, cerebral/cardiac ischaemia, retrograde brain perfusion, Bentall procedure, coronary artery bypass grafting, and aortic valve replacement significantly differed among the left-arm SBP tertiles. In-hospital mortality was 17.6% (46 of 262). Restricted cubic splines demonstrated that the relationship between presenting left-arm SBP and in-hospital mortality followed a U-shaped curve, whereas non-linearity was not detected in the right arm. This study found a U-shaped association between admission left-arm SBP and in-hospital mortality in ATAAD surgery patients, whereas a non-linearity relationship was not detected for right-arm SBP. Low left-arm SBP independently correlated with increased in-hospital mortality, underscoring the significance of bilateral blood pressure differences in ATAAD prognosis. [ABSTRACT FROM AUTHOR]

This study aimed to analyse the baseline characteristics of patients admitted with acute type A aortic syndrome (ATAAS) and to identify the potential predictors of in-hospital mortality in surgically managed patients. Data regarding demographics, clinical presentation, laboratory work-up, and management of 501 patients with ATAAS enrolled in the National Registry of Aortic Dissections—Romania registry from January 2011 to December 2022 were evaluated. The primary endpoint was in-hospital all-cause mortality. Multivariate logistic regression was conducted to identify independent predictors of mortality in patients with acute Type A aortic dissection (ATAAD) who underwent surgery. The mean age was 60±11 years and 65% were male. Computed tomography was the first-line diagnostic tool (79%), followed by transoesophageal echocardiography (21%). Cardiac surgery was performed in 88% of the patients. The overall mortality in the entire cohort was 37.9%, while surgically managed ATAAD patients had an in-hospital mortality rate of 29%. In multivariate logistic regression, creatinine value (OR 6.76), ST depression on ECG (OR 6.3), preoperative malperfusion (OR 5.77), cardiogenic shock (OR 5.77), abdominal pain (OR 4.27), age ≥70 years (OR 3.76), and syncope (OR 3.43) were independently associated with in-hospital mortality in surgically managed ATAAD patients. Risk stratification based on the variables collected at admission may help to identify ATAAS patients with high risk of death following cardiac surgery. [ABSTRACT FROM AUTHOR]

Patients with dementia are at increased risk for adverse events following valvular surgery. Outcomes after mitral transcatheter edge-to-edge repair (TEER) for mitral regurgitation in this vulnerable population are not well understood. We queried the National Inpatient Sample database for all hospitalizations for mitral TEER between 2016 and 2019. Patients with a validated diagnosis code for dementia were identified by ICD-10 codes and compared to a matched cohort of non-dementia patients using multivariable regression analysis. The primary outcome was in-hospital mortality. Secondary outcomes were hospital length of stay, discharge to nursing facility, total hospital charges, and in-hospital adverse events. 24,550 hospitalizations for mitral TEER were identified, including 880 patients (3.6 %) with dementia. Dementia was associated with higher in-hospital mortality (OR 4.31, 95 % CI 2.65 to 6.99, p < 0.001), prolonged length of hospital stay (OR 1.33, 95 % CI 1.12 to 1.57, p 0.001), higher discharge rate to nursing facility (OR 2.71, 95 % CI 2.13–3.44, p < 0.001), and higher rate of in-hospital adverse events including delirium (OR 5.88, 95 % CI 4.06 to 8.52, p < 0.001) and acute stroke (OR 8.87, 95 % CI 5.01 to 15.70, p < 0.001). Dementia is associated with worse post-procedural outcomes after mitral TEER. Further investigation is needed to elucidate mechanisms of poor clinical outcomes and guide shared decision-making in this vulnerable population. • Patients with dementia are at risk of worse post-procedural outcomes after mitral transcatheter edge-to-edge repair. • They are associated with higher in-hospital mortality, delirium, stroke, and prolonged hospital stays. • Shared decision making is key in this vulnerable population when mitral regurgitation is symptomatic.

• AKI is a frequent complication in critically-ill nonagenarians. • Even mild AKI has substantial negative impact on mortality and adverse outcomes. • Predictive ability applies to AKI defined by creatinine but not urine output criteria. The increasing admissions of very elderly patients to intensive care units (ICUs) over recent decades highlight a growing need for understanding acute kidney injury (AKI) in this population. Although these individuals are potentially at high risk for AKI and adverse outcomes, data on AKI in this population is scarce. This study investigates the AKI incidence and outcomes of critically-ill patients aging at least 90 years. This retrospective cohort study conducted at the Department of Intensive Care Medicine, University Medical Centre Hamburg-Eppendorf, Germany (2008–2020), investigates AKI incidence and outcomes between 2008 and 2020 in critically-ill patients aged ≥ 90 years. AKI was defined according to Kidney Disease: Improving Global Outcomes (KDIGO) criteria using creatinine dynamics and/or urine output. Primary endpoint was overall mortality after 1 year. Secondary endpoints were in-hospital mortality, length of ICU and hospital stay. During the study period 92,958 critically-ill patients were treated and 1108 were ≥ 90 years. Of these, 1054 patients had available creatinine values and were included in the present study. AKI occurred in 24.4%, mostly classified as mild (17.5%). AKI was independently associated with a significant increase in overall mortality (HR 1.21, 95 %-CI: 1.01–1.46), in-hospital mortality (OR 2, 1.41–2.85), length of ICU (+2.8 days, 2.3–3.3) and hospital stay (+2.3 days, 0.9–3.7). Severity escalated these effects, but even mild AKI showed significance. Introducing urine-based criteria increased incidence but compromised mortality prediction. AKI is a frequent complication in very elderly critically-ill patients. Occurrence of AKI at any stage was associated with increased mortality. Predictive ability applied to AKI defined by creatinine but not urine output. Careful attention of creatinine dynamics is essential in very elderly ICU-patients. [ABSTRACT FROM AUTHOR]

• Inappropriate in-hospital settings increase clinical risk for acute medical patients. • A Medical Admission Unit run by Internists redesigned the acute patient flow. • MAU ensured a high turn-over downsizing the outlying phenomenon. • MAU centralised unstable medical patients reducing in-hospital mortality. • A patient-centred and problem-oriented approach lowers clinical risk. the burden of acute complex patients, increasingly older and poli-pathological, accessing to Emergency Departments (ED) leads up hospital overcrowding and the outlying phenomenon. These issues highlight the need for new adequate patients' management strategies. The aim of this study is to analyse the effects on in-hospital patient flow and clinical outcomes of a high-technology and time-limited Medical Admission Unit (MAU) run by internists. all consecutive patients admitted to MAU from Dec-2017 to Nov-2019 were included in the study. The admissions number from ED and hospitalization rate, the overall in-hospital mortality rate in medical department, the total days of hospitalization and the overall outliers bed days were compared to those from the previous two years. 2162 patients were admitted in MAU, 2085(95.6%) from ED, 476(22.0%) were directly discharged, 88(4.1%) died and 1598(73.9%) were transferred to other wards, with a median in-MAU time of stay of 64.5 [0.2–344.2] hours. Comparing the 24 months before, despite the increase in admissions/year from ED in medical department (3842 ± 106 in Dec2015–Nov2017 vs 4062 ± 100 in Dec2017-Nov2019, p <0.001), the number of the outlier bed days has been reduced, especially in surgical department (11.46 ± 6.25% in Dec2015–Nov2017 vs 6.39 ± 3.08% in Dec2017-Nov2019, p =0.001), and mortality in medical area has dropped from 8.74 ± 0.37% to 7.29 ± 0.57%, p <0.001. over two years, a patient-centred and problem-oriented approach in a medical admission buffer unit run by internists has ensured a constant flow of acute patients with positive effects on clinical risk and quality of care reducing medical outliers and in-hospital mortality.

The quality of care for patients may be partly determined by the time they are admitted to the hospital. This study was conducted to explore the effect of admission time and describe the pattern and magnitude of weekly variation in the quality of patient care. A retrospective observational study. Data were collected from the Medical Care Quality Management and Control System for Specific (Single) Diseases in China. A total of 238,122 patients treated for acute ischemic stroke between January 2015 and December 2017 were included. The primary outcomes were completion of the ten process indicators and in-hospital death. The quality of in-hospital care varied according to hospital arrival time. We identified several patterns of variation across the days of the week. In the first pattern, the quality of four indicators, such as stroke physicians within 15 min, was lowest for arrivals between 08:00 and 11:59, increased throughout the day, and peaked for arrivals between 20:00 and 23:59 or 00:00 and 03:59. In the second pattern, the quality of four indicators, such as the application of antiplatelet therapy within 48 h, was not significantly different between days and weeks. There was no difference in in-hospital mortality between the different admission times. The effect of admission time on the quality of in-hospital care of patients with acute ischemic stroke showed several diurnal patterns. Detecting the times when quality is relatively low may lead to quality improvements in health care. Quality improvement should also focus on reducing diurnal temporal variation.

Patients with combined burns and trauma are often seen in the United States. The combination of trauma with burns increases mortality. In contrast, the characteristics and outcomes of these cases remain unknown in Japan. This study investigated the characteristics and outcomes of trauma associated with burns in Japan. This multicenter retrospective cohort study was conducted by utilizing data from the Japan Trauma Data Bank for the period between 2004 and 2017. We evaluated the characteristics of burn patients (n = 5783) divided into two groups: burns only (n = 5537) and combined burns and trauma (n = 246). Clinical characteristics, including patient background, severity of trauma, injury mechanism, total body surface area affected, injury location, treatments, and clinical outcomes, were examined. Most patients in both the groups were injured by flames. The number proportion of patients with 40–89% of the total body surface area affected was 1069/5537 (19.3%) in the burn-only group and 23/246 (9.3%) in the combined burn and trauma group. The in-hospital mortality was 1006/5537 (18.2%) in the burn-only group and 17/246 (6.9%) in the combined burn and trauma group. We demonstrated the characteristics of Japanese patients with burns only compared with those with combined burns and trauma. Flames were the main cause of burns, and in-hospital mortality was lower in the combined burn and trauma group associated with a smaller burn area. ● Flames were the main cause of burns in patients with burns and trauma in Japan. ● The combined burns and trauma group had a smaller burn area and less mortality. ● Trauma was not significantly associated with mortality in burn and trauma patients.

MRSA (methicillin-resistant Staphylococcus aureus)-infective endocarditis (IE) is associated with high morbidity and mortality. This study aimed to assess data from patients with MRSA-IE across multiple facilities in Japan, with a specific focus on antimicrobial therapy and prognosis. This retrospective study enrolled patients with a confirmed diagnosis of IE attributed to MRSA, spanning the period from January 2015 to April 2019. Sixty-four patients from 19 centers were included, with a median age of 67 years. The overall mortality rate was 28.1% at 30 days, with an in-hospital mortality of 45.3%. The most frequently chosen initial anti-MRSA agents were glycopeptide in 67.2% of cases. Daptomycin and linezolid were selected as initial therapy in 23.4% and 17.2% of cases, respectively. Approximately 40% of all patients underwent medication changes due to difficulty in controlling infection or drug-related side effects. Significant prognostic factors by multivariable analysis were DIC for 30-day mortality and surgical treatment for 30-day and in-hospital mortality. For vancomycin as initial monotherapy, there was a trend toward a worse prognosis for 30-day and in-hospital mortality (OR, 6.29; 95%CI, 1.00–39.65; p = 0.050, OR, 3.61; 95%CI, 0.93–14.00; p = 0.064). Regarding the choice of initial antibiotic therapy, statistical analysis did not show significant differences in prognosis. Glycopeptide and daptomycin were the preferred antibiotics for the initial therapy of MRSA-IE. Antimicrobial regimens were changed for various reasons. Prognosis was not significantly affected by choice of antibiotic therapy (glycopeptide, daptomycin, linezolid), but further studies are needed to determine which antimicrobials are optimal as first-line agents.

Infective endocarditis (IE) caused by MRSA (methicillin-resistant Staphylococcus aureus) is associated with a high mortality rate. This study aimed to elucidate the characteristics of patients with MRSA-IE in Japan and identify the factors associated with prognosis. This retrospective study included patients with a confirmed diagnosis of IE caused by MRSA, between January 2015 and April 2019. A total of 65 patients from 19 centers were included, with a mean age of 67 years and 26 % were female. Fifty percent of the patients with IE were had nosocomial infections and 25 % had prosthetic valve involvement. The most common comorbidities were hemodialysis (20 %) and diabetes (20 %). Congestive heart failure was present in 86 % of patients (NYHA class I, II: 48 %; III, IV: 38 %). The 30-day and in-hospital mortality rates were 29 % and 46 %, respectively. Multi-organ failure was the primary cause of death, accounting for 43 % of all causes of death. Prognostic factors for in-hospital mortality were age, disseminated intravascular coagulation, daptomycin and/or linezolid as initial antibiotic therapy, and surgery. Surgical treatment was associated with a lower mortality rate (odds ratio [OR], 0.026; 95 % confidence interval [CI], 0.002–0.382; p = 0.008 for 30-day mortality and OR, 0.130; 95 % CI; 0.029–0.584; p = 0.008 for in-hospital mortality). Mortality due to MRSA-IE remains high. Surgical treatment is a significant prognostic predictor of MRSA-IE. [ABSTRACT FROM AUTHOR]

One strategy to increase the availability of neurosurgical services in underserved regions within Sub-Saharan African countries is to create new residency training programs outside of cosmopolitan cities where programs may already exist. In 2016 Tenwek Hospital in rural western Kenya began offering full-time neurosurgical services and in 2020 inaugurated a residency training program. This review highlights the operative epidemiology of the first 5 years of the hospital's neurosurgical department. A retrospective review of all cases performed by a neurosurgeon at Tenwek Hospital between September 2016 and February 2022 was performed. Patient demographics, surgical indications, length of stay, and in-hospital mortality rates were collected. A total of 1756 cases were retrievable. Of these, 1006 (57.3%) were male and mean age was 30 years (range 1 day to 97 years). Mean length of stay was 11 ± 2 days and in-hospital mortality rate was 4.4% (77 patients). The most common pathologies in children comprised hydrocephalus and spina bifida (42.5% and 21.1%, respectively); in adults, cranial trauma (28.2%), oncology (25.2%), and degenerative spine (18.5%) were most common. Trauma was the leading cause of death. The neurosurgical caseload of a rural hospital in an underserved area can provide not only an adequate neurosurgical volume, but a robust and varied exposure that is necessary for training safe and competent surgeons who are willing to remain in their countries of origin.

Heart transplantation (HT) in patients with failing univentricular circulation is often challenging. This is compounded by the ever-increasing number of patients with prior Norwood-type reconstruction of the aorta, large aortic root, and often dense adhesions from multiple prior operations. We aimed to elucidate differences in outcomes of HT in patients with prior univentricular palliations, with and without prior Norwood-type aortic arch reconstruction (ArchRec). All patients who underwent HT for failed univentricular palliation during the 1990–2022 period were included in the study. Of 45 patients, 18 had undergone ArchRec. Hospital mortality improved in the recent era (17.4% before 2006 vs 0% after 2006; p=0.11), despite a higher proportion of patients with ArchRec (17.4% before 2006 vs 60.8% after 2006, p=0.002). Patients with ArchRec had a higher number of prior cardiac surgeries (4.1±1.5 vs 3.2±1.3, p=0.04), longer cardiopulmonary bypass time (320±23 vs 242±21 min, p=0.02), more concomitant arch reconstruction (33.3% vs 0%, p=0.02), greater need for post-HT extracorporeal membrane oxygenation (33.3% vs 3.7%; p=0.01) and longer hospital stay (37.1±30.5 days vs 23.6±11.8 days, p=0.04). Freedom from death or retransplantation for all patients was 91%, 73%, 67%, and 53% at 1, 5, 10, and 15-years, respectively. Prior ArchRec, Fontan procedure, and earlier eras were not risk factors for death. The outcomes of HT after univentricular palliation have improved in recent times and low operative mortality can be achieved. Despite increased complexity, good similar outcomes can be achieved in patients with and without prior arch reconstruction regardless of the palliation stage. [ABSTRACT FROM AUTHOR]

Burn patients in rural areas may encounter poorer outcomes associated with barriers to care; however, residence has not been studied in a large sample. The association between rural-versus-urban residence and outcomes after burn was examined using the National Inpatient Sample (NIS) database. Using the 2019 NIS database, patients over 18 years with a primary diagnosis of burn or corrosive injury were included. Level of urbanization was categorized into six groups. Outcomes after burn such as in-hospital mortality, multifactorial shock, prolonged mechanical ventilation, length of stay, and total costs were analyzed after adjusting for demographic factors and hospital characteristics. We included 4671 records, which represented a weighted population of 23,085 patients. Rural residence was associated with higher percentage of prior transfer but not in-hospital mortality. Compared to the most urbanized counties, encounters from the most rural counties were associated with higher odds of shock (aOR:2.62, 99% CI: 1.04–6.56, p = 0.007). Burn encounters from less urbanized counties did not experience differences in mortality, rates of skin grafting, prolonged mechanical ventilation, length of stay, or overall costs. However, odds of shock were higher among the least urbanized counties. Despite improved triage and transportation systems across the US, disparities and challenges exist for burn patients from rural residence. • Rural patients experience different barriers to care than urban or sub-urban counterparts. • In the NIS database, rural residence was associated higher likelihood of developing shock (of all types). • Transfer from a non-acute care hospital could be associated with higher odds of morbidity including shock. • Rural residence was not associated with increased in-hospital mortality, rates of skin grafting or increased cost. • Time from injury to treatment at a burn center is still needed to understand optimal care for rural patients.

Acute decompensated heart failure (ADHF) is a leading cause of cardiovascular disease hospitalisations associated with significant morbidity and mortality. In hospitals, HF patients are typically managed by cardiology or physician teams, with differences in patient demographics and clinical outcomes. This study utilises contemporary HF registry data to compare patient characteristics and outcomes in those with ADHF admitted into General Medicine and Cardiology units. The Victorian Cardiac Outcomes Registry was utilised to identify patients hospitalised with ADHF 30-day period in each of four consecutive years. We compared patient characteristics, pharmacological management and outpatient follow-up of patients admitted to General Medicine and Cardiology units. Primary outcome measures included in-hospital mortality, 30-day readmission, and 30-day mortality. Between 2014 and 2017, a total of 1,253 patients with ADHF admissions were registered, with 53% admitted in General Medicine units and 47% in Cardiology units. General Medicine patients were more likely to be older (82 vs 71 years; p<0.001), female (51% vs 34%; p<0.001), and have higher prevalence of comorbidities and preserved left ventricular function (p<0.001). There were no differences in primary outcome measures between General Medicine and Cardiology in terms of: in-hospital mortality (5.0% vs 3.9%; p=0.35), 30-day readmission (23.4% vs 23.6%; p=0.93), and 30-day mortality (10.0% vs 8.0%; p=0.21). Hospitalised patients with HF continue to have high mortality and rehospitalisation rates. The choice of treatment by General Medicine or Cardiology units, based on the particular medical profile and individual needs of the patients, provides equivalent outcomes. [ABSTRACT FROM AUTHOR]

There is limited real-world data highlighting recent temporal in-hospital morbidity and mortality trends for cases of acute myocardial infarction complicated by cardiogenic shock. The role of mechanical circulatory support within this patient population remains unclear. The US National Inpatient Sample database was sampled from 2011 to 2018 identifying 206,396 hospitalizations with a primary admission diagnosis of ST- or Non-ST elevation myocardial infarction complicated by cardiogenic shock. The primary outcomes included trends of all-cause in-hospital mortality, mechanical circulatory support use, and sex-specific trends for acute myocardial infarction complicated by cardiogenic shock (AMI-CS) over the study period. The annual number of AMI-CS hospitalizations increased from 22,851 in 2011 to 30,015 in 2018 and in-hospital mortality trends remained similar (42.9 % to 43.7 %, ptrend < 0.001). The proportion of patients receiving any temporary MCS device decreased (46.4 % to 44.4 %). The use of intra-aortic balloon pump (IABP) decreased (44.9 % to 32.9 %) and the use of any other non-IABP MCS device increased (2.5 % to 15.6 %), ptrend<0.001. Sex-specific mortality indicate female in-hospital mortality remained similar (50.3 % to 51 %, ptrend<0.001), but higher than male in-hospital mortality, which increased non-significantly (38.8 % to 40.2 %, ptrend = 0.372). From 2011 to 2018, hospitalizations for AMI-CS patients have increased in number. However, there has been no recent appreciable change in AMI-CS mortality despite a changing treatment landscape with decreasing use of IABPs and increasing use of non-IABP MCS devices. Further research is necessary to examine the appropriate use of MCS devices within this population. • AMI complicated by cardiogenic shock (AMI-CS) is a highly morbid condition. • The number of AMI-CS cases has increased from 22,851 in 2011 to 30,015 in 2018 and mortality has remained unchanged at 40–45%. • Intra-aortic balloon pump use in AMI-CS patients is decreasing (44.9% to 32.9%, p-value<0.001). • Use of other temporary mechanical circulatory devices is increasing (2.5% to 15.6%, p-value<0.001). • Mortality of female AMI-CS patients is consistently nearly 10 % higher than males.

Surgical risk stratification is crucial for enhancing perioperative assistance and allocating resources efficiently. However, existing models may not capture the complexity of surgical care in Brazil. Using data from various healthcare settings nationwide, we developed a new risk model for 30-day in-hospital mortality (the Ex-Care BR model). A retrospective cohort study was conducted in 10 hospitals from different geographic regions in Brazil. Data were analysed using multilevel logistic regression models. Model performance was assessed using the area under the receiver operating characteristic curve (AUROC), Brier score, and calibration plots. Derivation and validation cohorts were randomly assigned. A total of 107,372 patients were included, and 30-day in-hospital mortality was 2.1% (n =2261). The final risk model comprised four predictors related to the patient and surgery (age, ASA physical status classification, surgical urgency, and surgical size), and the random effect related to hospitals. The model showed excellent discrimination (AUROC=0.93, 95% confidence interval [CI], 0.93–0.94), calibration, and overall performance (Brier score=0.017) in the derivation cohort (n =75,094). Similar results were observed in the validation cohort (n =32,278) (AUROC=0.93, 95% CI, 0.92–0.93). The Ex-Care BR is the first model to consider regional and organisational peculiarities of the Brazilian surgical scene, in addition to patient and surgical factors. It is particularly useful for identifying high-risk surgical patients in situations demanding efficient allocation of limited resources. However, a thorough exploration of mortality variations among hospitals is essential for a comprehensive understanding of risk. NCT05796024. [ABSTRACT FROM AUTHOR]

Among patients having elective abdominal surgery, how much does preoperative physiotherapy education with breathing exercise training reduce the incidence of postoperative pulmonary complications (PPCs), hospital length of stay and 12-month mortality? How stable are the treatment effects across different PPC definitions, including pneumonia? How much do the treatment effects on PPC, hospital length of stay and mortality vary within clinically relevant subgroups? Individual participant-level meta-analysis (n = 800) from two randomised controlled trials analysed with multivariable regression. Adults undergoing major elective abdominal surgery. Experimental participants received a single preoperative session with a physiotherapist within 4 weeks of surgery and educated on PPC prevention with breathing exercises and early mobilisation. They were taught breathing exercises and instructed to start them immediately on waking from surgery. The control group received no preoperative or postoperative physiotherapy, or early ambulation alone. PPC, hospital length of stay and 12-month mortality. Participants who received preoperative physiotherapy had 47% lower odds of developing a PPC (adjusted OR 0.53, 95% CI 0.34 to 0.85). This effect was stable regardless of PPC definition. Effects were greatest in participants who smoked, were aged ≤ 45 years, had abnormal body weight, had multiple comorbidities, or were undergoing bariatric or upper gastrointestinal surgery. Participants having operations ≤ 3 hours in duration were least responsive to preoperative physiotherapy. Participants with multiple comorbidities were more likely to have a shorter hospital stay if provided with preoperative physiotherapy (adjusted MD –3.2 days, 95% CI –6.2 to –0.3). Effects on mortality were uncertain. There is strong evidence to support preoperative physiotherapy in preventing PPCs after elective abdominal surgery. [ABSTRACT FROM AUTHOR]

Temporary mechanical circulatory support as well as multidisciplinary team approach in a regional care organization might improve survival of cardiogenic shock. No study has evaluated the relative effect of each temporary mechanical circulatory support on mortality in the context of a regional network. Prospective observational data were retrieved from patients consecutively admitted with cardiogenic shock to the intensive care units in 3 centers organized into a regional cardiac assistance network. Temporary mechanical circulatory support indication was decided by a heart team, based on the initial shock severity or if shock was refractory to medical treatment within 24 hours of admission. A propensity score for circulatory support use was used as an adjustment co-variable to emulate a target trial. The primary endpoint was in-hospital mortality. Two hundred and forty-six patients were included in the study (median age: 59.5 years, 71.9% male): 121 received early mechanical assistance. The main etiologies were acute myocardial infraction (46.8%) and decompensated heart failure (27.2%). Patients who received early mechanical assistance had more severe conditions than other patients. Their crude in-hospital mortality was 38% and 22.4% in other patients but adjusted in-hospital mortality was not different (hazard ratio 0.91, 95% CI:0.65–1.26). Patients with mechanical assistance had a higher rate of complications than others with longer Intensive Care Unit and hospital stays. In the conditions of a cardiac assistance regional network, in-hospital mortality was not improved by early mechanical assistance implantation. A high incidence of complications of temporary mechanical circulatory support may have jeopardized its potential benefit. [ABSTRACT FROM AUTHOR]

In patients undergoing transcatheter aortic valve replacement (TAVR), cerebral embolic protection devices (CEPD) are used to possibly diminish the risk of periprocedural stroke. Trends and outcomes of CEPD usage in TAVR are not well characterized. National readmission databases (NRD) 2017–2019 was used to identify hospital admissions for TAVR using ICD-10 codes, with versus without Sentinel CEPD. Primary outcomes of the study were in-hospital and 30-day stroke. Secondary outcomes include in-hospital mortality, 30-day mortality, 30-day readmission rate, and other procedural complications. We matched both cohorts using propensity score matching (PSM) and performed logistic regression to compute the odds ratios (ORs) and corresponding 95 % confidence intervals (CI). Out of 190,837 TAVR admissions in the United States, 10,643 (5.6 %) patients had TAVR with Sentinel CEPD. After propensity score matching, our cohort included 10,503 patients with CEPD and 10,541 without CEPD. Trends in CEPD utilization are noted in Fig. 1. In the PSM cohort, Sentinel CEPD was not associated with decreased risk of in-hospital stroke (1.9 % vs. 1.8 %, OR: 0.98, 95 % CI: 0.76–1.26, p = 0.88), 30-day stroke (2.1 % vs. 2.1 %, OR: 1.01, 95 % CI: 0.78–1.30, p = 0.96), or 30-day mortality (1.3 % vs. 1.0 %, OR: 0.74, 95 % CI: 0.51–1.07, p = 0.11) when compared to TAVR without CEPD. Other in-hospital and short-term outcomes post-TAVR were not impacted by Sentinel CEPD usage, including acute kidney injury, vascular complications, paravalvular leak, cardiogenic shock, circulatory support, or permanent pacemaker (Table 1). In this nationally representative cohort, Sentinel CEPD utilization during transfemoral TAVR for stroke prevention was not associated with reduced odds of in-hospital stroke, 30-day stroke, or 30-day mortality. Future studies should focus on optimizing patient selection for CEPD and establishing predictive models to identify the subset of TAVR patients with higher risk for periprocedural stroke who might benefit from CEPD.

Regional variations in acute coronary syndrome (ACS) management and outcomes have been an enormous public health issue. However, studies have yet to explore how to reduce the variations. The National Chest Pain Center Program (NCPCP) is the first nationwide, hospital-based, comprehensive, continuous quality improvement program for improving the quality of care in patients with ACS in China. We evaluated the association of NCPCP and regional variations in ACS healthcare using generalized linear mixed models and interaction analysis. Patients in the Western region had longer onset-to-first medical contact (FMC) time and time stay in non-percutaneous coronary intervention (PCI) hospitals, lower rates of PCI for ST-elevation myocardial infarction (STEMI) patients, and higher rates of medication usage. Patients in Central regions had relatively lower in-hospital mortality and in-hospital heart failure rates. Differences in the door-to-balloon time (DtoB) and in-hospital mortality between Western and Eastern regions were less after accreditation (β = −8.82, 95% confidence interval (CI) −14.61 to −3.03; OR = 0.79, 95%CI 0.70 to 0.91). Similar results were found in differences in DtoB time, primary PCI rate for STEMI between Central and Eastern regions. The differences in PCI for higher-risk non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients among different regions had been smaller. Additionally, the differences in medication use between Eastern and Western regions were higher after accreditation. Regional variations remained high in this large cohort of patients with ACS from hospitals participating in the NCPCP in China. More comprehensive interventions and hospital internal system optimizations are needed to further reduce regional variations in the management and outcomes of patients with ACS.

Spontaneous intracerebral hemorrhage (ICH) poses a public health issue due to its elevated mortality rates. The International Normalized Ratio-platelet index (INR-Plt index) has recently been recognized as a predictive factor for liver disease progression. The potential of applying the INR-Plt index in forecasting ICH prognosis presents an intriguing subject. This study endeavors to examine the correlation between the INR-Plt index and hospital outcomes in patients with spontaneous supratentorial ICH. A retrospective examination of 283 adult ICH patients was undertaken. The INR-Plt index was computed using the formula: [INR/platelet counts (1000/μL)] × 100. The clinical outcomes evaluated consisted of mortality rates and the Modified Rankin Scale (mRS) at discharge. An unfavorable outcome was defined as an mRS score from 4 to 6. The study found a significant correlation between the INR-Plt index and hospital mortality (odds ratio: 4.31, 95% CI: 1.07–17.31, P = 0.04). There was a 43% rise in mortality risk for every 0.1 unit increase in the INR-Plt index. Kaplan–Meier survival curves illustrated a considerably lower survival rate at discharge for patients with an INR-Plt index >0.8 (log-rank test: P = 0.047). Regarding unfavorable outcomes, the INR-Plt index was not a significant factor according to logistic regression analyses. The INR-Plt index is a predictor of hospital mortality in patients with spontaneous supratentorial ICH. A higher INR-Plt index value is associated with an increased risk of mortality, underlining the potential usefulness of this composite index in guiding clinical decision-making and enabling risk stratification.

To explore the clinical value of various complete blood count (CBC)-derived inflammation indicators to predict in-hospital mortality in patients with extensive burns. Systemic inflammation indexes, including lymphocyte-platelet ratio (LPR), neutrophil-lymphocyte ratio (NLR), neutrophil-monocyte ratio (NMR), monocyte-lymphocyte ratio (MLR), neutrophil-to-lymphocyte * platelet (NLPR), systemic inflammation index (SII), and systemic inflammation response index (SIRI) on days 1, 3, and 7 after admission were calculated in 135 patients with extensive burns. We included 135 patients with extensive burns, including 97 survivors and 38 non-survivors. After adjusting for confounders, only the LPR on day 1, NLPR on days 3 and 7 were significantly associated with survival (OR= 1.237, 1.097, 1.104; 95 % CI: 1.055–1.451, 1.002–1.202, 1.005–1.212; respectively) in the analysis of multivariate logistic regression. The optimum cutoff values of the LPR on day 1 and NLPR on day 3 were 6.37 and 8.06, and the area under the curves (AUC) were 0.695 and 0.794, respectively. The AUC of NLPR on day 7 had the highest value, 0.814, and the optimum cut-off value was 3.84. The efficacy of LPR on day 1, NLPR on days 3 and 7 combined with the burn prognostic score index in predicting the prognosis of patients was higher than that of the burn index alone, and the three composite inflammatory indexes combined with PBI had the highest efficacy in predicting the prognosis (AUC = 0.994). Kaplan-Meier survival analysis showed poor prognosis in patients with higher LPR on day 1 and higher NLPR on days 3 and 7 (log-rank χ2 = 9.623,31.564, 20.771, respectively; P < 0.01). LPR on day 1 and NLPR on days 3 and 7 after admission are reliable predictors of prognosis in patients with severe extensive burns. The combination of the burn prognostic score index, LPR on day 1, and NLPR on days 3 and 7 was superior to the burn indexes alone in predicting a patient's prognosis. • Extensive burns have poor prognosis and significant fatality rate. • A retrospective study discusses the impacts of combined routine blood indexes on prognosis of severe burns. • LPR on day 1 and NLPR on days 3 and 7 as independent prognostic markers for extensive burns. • A combination of the burn prognostic score indexes and systemic inflammation indexes is better to predict a patient's prognosis.

The relationship between body mass index (BMI) and outcomes in the acute care setting is controversial, with evidence suggesting that obesity is either protective - which is also called obesity paradox - or associated with worse outcomes. The purpose of this study was to assess whether BMI was related to frailty and biological age, and whether BMI remained predictive of mortality after adjusting for frailty and biological age. Of the 2950 patients who had a biological age estimated on admission to the intensive care unit, 877 (30 %) also had BMI and frailty data available for further analysis in this retrospective cohort study. Biological age of each patient was estimated using the Levine PhenoAge model based on results of nine blood tests that were reflective of DNA methylation. Biological age in excess of chronological age was then indexed to the local study context by a linear regression to generate the residuals. The associations between BMI, clinical frailty scale, and the residuals were first analyzed using univariable analyses. Their associations with mortality were then assessed by multivariable analysis, including the use of a 3-knot restricted cubic spline function to allow non-linearity. Both frailty (p = 0.003) and the residuals of the biological age (p = 0.001) were related to BMI in a U-shaped fashion. BMI was not related to hospital mortality, but both frailty (p = 0.015) and the residuals of biological age (OR per decade older than chronological age 1.50, 95 % confidence interval [CI] 1.04–2.18; p = 0.031) were predictive of mortality after adjusting for chronological age, diabetes mellitus and severity of acute illness. BMI was significantly associated with both frailty and biological age in a U-shaped fashion but only the latter two were related to mortality. These results may, in part, explain why obesity paradox could be observed in some studies. [ABSTRACT FROM AUTHOR]

This study aims to investigate independent factors associated with 30-day mortality in patients with acute spontaneous intracerebral hemorrhage (SICH) before treatment. A retrospective analysis was performed on medical records of patients hospitalized with acute SICH between 2019 and 2021. Data included personal history, hospital stay duration, symptom onset, chief complaint, underlying diseases, medication, and alcohol/smoking habits. Physical examination records comprised baseline blood pressure, Glasgow Coma Scale assessment, and pupil reaction evaluation. Diagnostic imaging, specifically computed tomography brain scans, was examined for hemorrhage details. Multivariable logistic analysis was utilized for data analysis. Among 663 cases, 185 (27.9%) experienced mortality. Risk factors for mortality included chronic kidney disease, ischemic heart disease, loss of follow-up in hypertension clinic, and pontine hemorrhage. Conversely, motor response (m), reactive pupils, and basal cistern persistence significantly decreased the risk of mortality in multivariable analysis. Receiver operating characteristic analysis identified a m score of 5 as the cutoff for predicting survival. Chronic kidney disease, ischemic heart disease, loss of hypertension follow-up, m, reactive pupils, pontine hemorrhage, and basal cistern persistence were independent variables associated with the 30-day mortality rate in SICH patients before treatment initiation. A m, pupil reaction, and basal cistern persistence serve as predictive tools for assessing mortality in SICH before treatment. [ABSTRACT FROM AUTHOR]

The impact on age on the short-term and long-term prognosis in patients with Takotsubo syndrome (TTS) is unclear. We aimed to evaluate whether age has prognostic implications during hospital stay and long-term follow-up of TTS patients. 688 consecutive patients were admitted for TTS in 7 tertiary centers from January-2008 to June-2021. We divided our cohort into two groups (patients <75 years and ≥75 years). Clinical, analytical, and hemodynamic variables as well as in-hospital management were registered and compared between groups. Mortality rates during hospital stay and follow-up were assessed. Adverse cardiovascular events (ACE) were defined as the composite of cardiovascular death, heart failure event, acute myocardial infarction, stroke and symptomatic arrhythmia. Median age was 74.7 years and 49.4 % were ≥75 years. 86.9 % were women and 22.3 % were secondary forms of TTS. In-hospital mortality was 3.6 % (1.5 % cardiovascular). Median clinical follow-up was 4.3 years. Mortality during the follow-up period was 23 % (5.0 % cardiovascular) while ACE were 22.5 %, mainly due to heart failure events. Kaplan-Meier curves showed both higher rates of mortality and ACE in ≥75 years group (30.2 % vs 15.8 %; p < 0.001 and 28.3 % vs 16.7 %; p < 0.001). Age was independently associated with higher rates of overall mortality and ACE in patients with TTS. Hypertension, absence of sinus rhythm, Killip class > I and a more impaired coronary microvascular resistance were also associated to ACE in TTS patients. Advanced age was associated with higher rate of overall mortality and ACE during long-term follow-up in TTS patients. Age as a prognostic variable during the follow-up in Takotsubo patients. A: Cardiac ventriculography in systole of a patient with Takotsubo syndrome showing dyskinesia of midventricular and apical segments (red arrows) with basal hypercontractility (green arrows); B: TTS patients with age ≥ 75 years presented a higher overall mortality during follow-up; C: TTS patients with age ≥ 75 years presented a higher percentage of adverse cardiovascular events during follow-up. [Display omitted] • Adverse cardiovascular events are frequent in Takotsubo syndrome during follow-up. • Age is related to adverse cardiovascular events during the follow-up in Takotsubo. • Increased age is associated with overall mortality during the follow-up in Takotsubo. • Gender, HTN, CKD and secondary forms are also associated to overall mortality. • HTN, sinus rhythm, Killip and CMD are related to cardiac prognosis in Takotsubo.

Type II odontoid fractures (OF) are among the most common cervical spine injuries in the geriatric population. However, there is a paucity of literature regarding their epidemiology. Additionally, the optimal management of these injuries remains controversial, and no study has evaluated the short-term outcomes of geriatric patients presenting to emergency departments (ED). This study aims to document the epidemiology of geriatric patients presenting to EDs with type II OFs and determine whether surgical management was associated with early adverse outcomes such as in-hospital mortality and discharge to skilled nursing facilities (SNF). This is a retrospective cohort study. Data was used from the 2016–2020 Nationwide Emergency Department Sample. Patient encounters corresponding to type II OFs were identified. Patients younger than 65 at the time of presentation to the ED and those with concomitant spinal pathology were excluded. The association between the surgical management of geriatric type II OFs and outcomes such as in-hospital mortality and discharge to SNFs. Patient, fracture, and surgical management characteristics were recorded. A propensity score matched cohort was constructed to reduce differences in age, comorbidities, and injury severity between patients undergoing operative and nonoperative management. Additionally, to develop a positive control for the analysis of geriatric patients with type II OFs and no other concomitant spinal pathology, a cohort of patients that had been excluded due to the presence of a concomitant spinal cord injury (SCI) was also constructed. Multivariate regressions were then performed on both the matched and unmatched cohorts to ascertain the associations between surgical treatment and in-hospital mortality, inpatient length of stay, encounter charges, and discharge to SNFs. A total of 11,325 encounters were included. The mean total charge per encounter was $60,221. 634 (5.6%) patients passed away during their encounters. In total, 1,005 (8.9%) patients were managed surgically. Surgical management of type II OFs was associated with a 316% increase in visit charge (95% CI: 291%–341%, p<.001), increased inpatient length of stay (IRR: 2.87, 95% CI: 2.62–3.12, p<.001), and increased likelihood of discharge to SNFs (OR=2.62, 95% CI: 2.26–3.05, p<.001), but decreased in-hospital mortality (OR=0.32, CI: 0.21-0.45, p<.001). The propensity score matched cohort consisted of 2,010 patients, matching each of the 1,005 that underwent surgery to 1,005 that did not. These cohorts were well balanced across age (78.24 vs 77.91 years), Elixhauser Comorbidity Index (3.68 vs 3.71), and Injury Severity Score (30.15 vs 28.93). This matching did not meaningfully alter the associations determined between surgical management and in-hospital mortality (OR=0.34, CI=0.21–0.55, p<.001) or SNF discharge (OR=2.59, CI=2.13–3.16, p<.001). Lastly, the positive control cohort of patients with concurrent SCI had higher rates of SNF discharge (50.0% vs 42.6%, p<.001), surgical management (32.3% vs 9.7%, p<.001), and in-hospital mortality (28.9% vs 5.6%, p<.001). This study lends insight into the epidemiology of geriatric type II OFs and quantifies risk factors influencing adverse outcomes. Patient informed consent should include a discussion of the protective association between definitive surgical management and in-hospital mortality against potential operative morbidity, increased lengths of hospital stay, and increased likelihood of discharge to SNFs. This information may impact patient treatment selection and decision making. [ABSTRACT FROM AUTHOR]

• Intraoperative cardiac arrest (ICA) during liver transplantation (LT) is associated with elevated perioperative and in-hospital mortality rates. • Patients who experienced ICA during LT and received effective treatment demonstrated satisfactory long-term survival outcomes. • The identified risk factors for ICA during LT include hypothermia and hyperkalemia. Intraoperative cardiac arrest (ICA) during liver transplantation (LT) is a rare surgical complication that results in devastating outcomes. Moreover, previous worldwide studies have found inconsistencies in the risk factors associated with ICA in LT. This was a retrospective cohort study of adult patients who underwent LT between January and October 2021 at Siriraj Hospital, a tertiary care hospital. The incidence of ICA and outcomes of patients who experienced ICA were examined. Risk factors associated with ICA were investigated as a secondary objective. Among 342 patients, the incidence of ICA was 3.5% (95% CI 1.8%-6.1%). Of these, 33.3% died intraoperatively. Among patients with ICA, 41.7% died within 30 days, compared with only 7.6% in those without ICA (P =.002). Moreover, the in-hospital mortality rate of those with ICA was 58.3%, which was significantly higher than that of those without ICA (9.7%, P <.001). However, 41.7% of patients with ICA were discharged alive with long-term survival. Because ICA is a rare event, we found only 2 independent factors significantly associated with ICA. These factors include intraoperative temperature below 35°C, with an odds ratio (OR) of 6.07 (95% CI:1.32-27.88, P =.02) and elevated intraoperative serum potassium, with an OR of 4.57 (95% CI:2.15-9.67, P <.001). ICA is associated with high perioperative and in-hospital mortality. However, our findings suggest that with effective management of ICA, more than 40% of these patients could be discharged with excellent long-term outcomes. Hypothermia and hyperkalemia were independent risk factors significantly associated with ICA. [ABSTRACT FROM AUTHOR]

• Number of hospitalizations and mortality in Poland due to herpes zoster was relatively small. • Mean annual first-time herpes zoster hospitalization rate was 5.8 per 100,000 person-years. • Over 70 % of hospitalized patients due to herpes zoster were over 60 years old. • Risk factors included female gender, older age and residence in urban areas. The varicella-zoster virus (VZV) is an infectious agent that causes both chickenpox and herpes zoster/shingles (HZ). This infection can take various clinical forms, result in permanent complications, and be a marker of immunosuppression, e.g. in the course of a neoplastic disease. The aim of this study is to analyze epidemiological trends in hospitalization and hospital mortality rate among HZ patients in Poland (2012–2021). Our study is a population-based, retrospective analysis of hospital discharge records of patients with HZ. Data were obtained from the National Institute of Public Health in Poland, and they covered the period from 2012 to 2021. All hospitalization records with primary or secondary ICD-10 B02 code diagnosis were included in the study. We analyzed the total number of 23,432 hospital discharge records of HZ patients in 2012–2021. The study group consisted of 22,169 (94.6 %) hospitalization records of first-time diagnosis of HZ in hospitalized patients: 9,309 males (42 %) and 12,860 females (58 %). In this group, 70.3 % were patients over 60 years old. The mean and median age was 64 and 69 years, respectively. The mean annual first-time hospitalization rate for HZ was estimated to be 5.8 per 100,000 person-years (95 % CI: 4.8–6.7 per 100,000 person-years). The hospitalization rate for HZ was similar during 2012–2019. There was a significant decrease in hospitalizations in 2020–2021 in comparison with the previous years (R2 = 0.42, p < 0.05). Women showed a higher hospitalization rate than men (p < 0.001). Urban residents had a higher hospitalization rate than rural residents (p < 0.001). In the analyzed period, 246 deaths were recorded (1.1 % of all hospitalized HZ patients) −119 males and 127 females. The HZ-related number of hospitalizations and mortality in Poland are relatively low, but HZ is still a significant health problem. Risk factors include female gender, older age and residence in urban areas. [ABSTRACT FROM AUTHOR]

Due to the high rate of geriatric patient visits, scoring systems are needed to predict increasing mortality rates. In this study, we aimed to investigate the in-hospital mortality prediction power of the National Early Warning Score 2 (NEWS2) and the Laboratory Data Decision Tree Early Warning Score (LDT-EWS), which consists of frequently performed laboratory parameters. We retrospectively analyzed 651 geriatric patients who visited the emergency department (ED), were not discharged on the same day from ED, and were hospitalized. The patients were categorized according to their in-hospital mortality status. The NEWS2 and LDT-EWS values of these patients were calculated and compared on the basis of deceased and living patients. Median (interquartile range [IQR]) NEWS2 and LDT-EWS values of the 127 patients who died were found to be statistically significantly higher than those of the patients who survived (NEWS2: 5 [3–8] vs. 3 [1–5]; p < 0.001; LDT-EWS: 8 [7–10] vs. 6 [5–8]; p < 0.001). In the receiver operating characteristic curve analysis, the NEWS2, LDT-EWS, and NEWS2+LDT-EWS—formed by the sum of the two scoring systems—resulted in 0.717, 0.705, and 0.775 area under curve values, respectively. The NEWS2 and LDT-EWS were found to be valuable for predicting in-hospital mortality in geriatric patients. The power of the NEWS2 to predict in-hospital mortality increased when used with the LDT-EWS. [ABSTRACT FROM AUTHOR]

The utility of follow-up blood cultures (FUBC) for gram-negative bloodstream infections (BSIs) are controversial due to low rates of positivity. However, recent studies suggest higher rates of positivity in critically ill patients. The utility of FUBC in gram-negative BSI in patients with severe burn injuries is unknown. Patients ≥ 18 years old admitted to the US Army Institute of Surgical Research Burn Center for combat-related thermal burns from 1/2003–6/2014 with a monomicrobial BSI were included. FUBC were defined as repeat cultures 1–5 days from index BSI. Persistent BSI (pBSI) was defined as isolation of the same organism from initial and FUBC. The primary endpoint was all-cause in-hospital mortality in patients with gram-negative pBSI. Of 126 patients meeting inclusion criteria with BSI, 53 (42%) had pBSI. Compared to patients without persistence, patients with pBSI had more severe burns with median total body surface area (TBSA) burns of 47% ([IQR 34–63] vs. 35.3% [IQR 23.3–56.6], p = 0.02), increased mortality (38 vs. 11%, p = 0.001) compared to those with non-persistent BSI. On multivariate analysis, pBSI was associated with an odds ratio for mortality of 5.3 [95% CI 1.8–15.8, p = 0.003). Amongst gram-negative pathogens, persistence rates were high and associated with increased mortality (41% vs. 11%, p = 0.001) compared to patients without pBSI. In this cohort of military patients with combat-related severe burns, pBSI was more common than in other hospitalized populations and associated with increased mortality. Given this high frequency of persistence in patients with burn injuries and associated mortality, FUBC are an important diagnostic and prognostic study in this population. • Gram-negative bacteremia persistence is common in patients with severe burns. • Persistent gram-negative bacteremia is associated with increased mortality. • Bloodstream infections should be monitored with repeat blood cultures in severe burns.

Controversy surrounds the optimal therapy for submassive and massive pulmonary embolism (PE). We conducted a systematic review and meta-analysis to compare the outcomes of catheter-directed thrombolysis (CDT) versus surgical and catheter-based thrombectomy in patients with submassive and massive PE. We searched PubMed, EMBASE, Cochrane, and Google Scholar for studies comparing outcomes of CDT versus thrombectomy in submassive and massive PE. Studies were identified and data were extracted by two independent reviewers. A random effects model was used to calculate risk ratios (RRs) with 95 % confidence intervals (CIs). Outcomes included in-hospital mortality, procedural complications, hospital and intensive care unit (ICU) length of stay (LOS), 30-day readmissions, and right ventricle/left ventricle (RV/LV) ratio improvement. Eight observational studies with 1403 patients were included, of whom 50.0 % received CDT. Compared to thrombectomy, CDT was associated with significantly lower in-hospital mortality (RR 0.62; 95 % CI 0.43–0.89; p = 0.01) and similar rates of major bleeding (p = 0.61), blood transfusion (p = 0.41), stroke (p = 0.41), and atrial fibrillation (p = 0.71). The hospital and ICU LOS, 30-day readmissions, and degree of RV/LV ratio improvement were similar between the two strategies (all p > 0.1). In subgroup analyses, in-hospital mortality was similar between CDT and catheter-based thrombectomy (p = 0.48) but lower with CDT compared with surgical thrombectomy (p = 0.01). In patients with submassive and massive PE, CDT was associated with similar in-hospital mortality compared to catheter-based thrombectomy, but lower in-hospital mortality compared to surgical thrombectomy. Procedural complications, LOS, 30-day readmissions, and RV/LV ratio improvement were similar between CDT and any thrombectomy. Randomized controlled trials are indicated to confirm our findings. • Controversy surrounds the optimal therapy for submassive and massive PE. • CDT was associated with similar in-hospital mortality compared to catheter-based thrombectomy. • CDT was associated with lower in-hospital mortality compared to surgical thrombectomy. • CDT and thrombectomy had similar complications, LOS, 30-day readmissions, and RV/LV ratio improvement. • This study expands the evidence supporting CDT as a feasible option for submassive and massive PE.

Optimal reversal agent for direct oral anticoagulant (DOAC)–associated major bleeding has not been described. Before the approval of andexanet alfa (AA) in 2018, 4-factor prothrombin complex concentrate (4F-PCC) was recommended by major guidelines. Currently, AA is recommended as the first-line agent by most guidelines. With a paucity of literature comparing the 2 agents, there is clinical value in assessing hemostatic efficacy and safety of the 2 agents. This study aimed to evaluate hemostatic efficacy and safety of AA and 4F-PCC in all DOAC-associated major bleedings. A multicenter, retrospective chart review was performed of adult subjects who were admitted for a DOAC-associated major bleeding and received 4F-PCC from February 2018 to May 2019 or AA from May 2019 to September 2021. Some of the exclusion criteria included not receiving a DOAC, receiving multiple reversal agents during the same hospitalization, receiving reversal for any nonmajor bleeding indication, and not receiving the full dose of a reversal agent. The primary outcome was hemostatic efficacy 24 hours after the end of the reversal agent administration. Secondary outcomes included time to administration, hospital mortality, length of stay, need for surgery, and need for additional blood product. Safety outcome was incidence of thrombotic events. There were 99 subjects included in the 4F-PCC group and 84 subjects in the AA group. Hemostatic efficacy was achieved in 69 subjects (69.7%) in the 4F-PCC group and 63 subjects (75%) in the AA group (P = 0.927). In-hospital mortality was seen in 20 subjects (20.2%) in the 4F-PCC group and 10 subjects (11.9%) in the AA group. Thrombotic events were seen in 7 subjects (7.1%) in the 4F-PCC group and 6 subjects (7.1%) in the AA group. There were no significant differences in hemostatic efficacy, in-hospital mortality, and number of thrombotic events between 4F-PCC and AA. [ABSTRACT FROM AUTHOR]

Despite growing cardiogenic shock (CS) research in adults, the epidemiology, clinical features, and outcomes of children with CS are lacking. This study sought to describe the epidemiology, clinical presentation, hospital course, risk factors, and outcomes of CS among children hospitalized for acute decompensated heart failure (ADHF). We examined consecutive ADHF hospitalizations (<21 years of age) from a large single-center retrospective cohort. Patients with CS at presentation were analyzed and risk factors for CS and for the primary outcome of in-hospital mortality were identified. A modified Society for Cardiovascular Angiography and Interventions shock classification was created and patients were staged accordingly. A total of 803 hospitalizations for ADHF were identified in 591 unique patients (median age 7.6 years). CS occurred in 207 (26%) hospitalizations. ADHF hospitalizations with CS were characterized by worse systolic function (P = 0.040), higher B-type natriuretic peptide concentration (P = 0.032), and more frequent early severe renal (P = 0.023) and liver (P < 0.001) injury than those without CS. Children presenting in CS received mechanical ventilation (87% vs 26%) and mechanical circulatory support (45% vs 16%) more frequently (both P < 0.001). Analyzing only the most recent ADHF hospitalization, children with CS were at increased risk of in-hospital mortality compared with children without CS (28% vs 11%; OR: 1.91; 95% CI: 1.05-3.45; P = 0.033). Each higher CS stage was associated with greater inpatient mortality (OR: 2.40-8.90; all P < 0.001). CS occurs in 26% of pediatric hospitalizations for ADHF and is independently associated with hospital mortality. A modified Society for Cardiovascular Angiography and Interventions classification for CS severity showed robust association with increasing mortality. [Display omitted] [ABSTRACT FROM AUTHOR]

To assess the prevalence, all-cause mortality and determinants of advanced HIV disease (AHD) or severe immunosuppression (SIS) in the rural–urban communities of Southwestern China. Retrospective cohort study. Data on HIV/AIDS cases reported in 2005–20 were collected from Case Report System. A binary logistic regression model assessed the risk factors of AHD/SIS prevalence. Survival curves across rural–urban regions were compared using Kaplan–Meier estimates and log-rank tests. Determinants of all-cause mortality were identified using the Cox proportional hazard model. Among 14,533 newly diagnosed HIV/AIDS patients, 7497 (51.6%) presented with AHD and 2564 (17.6%) with SIS. Compared with urban patients, rural patients had a higher prevalence of AHD (56.7% vs 40.7%) and SIS (20.1% vs 12.4%), all-cause mortality (AHD 12.3 vs 5.6, SIS 16.3 vs 5.5, per 100 person-years). Their 5-year survival probability (AHD 59.5% vs 77.1%; SIS 54.4% vs 76.3%) and mean survival time (AHD 106.5 vs 140.6 months, SIS 95.3 vs 144.2 months, p < 0.0001) were lower. Rural patients had an increased risk of SIS prevalence (adjusted odds ratios 1.45, 95% confidence interval [CI] 1.28–1.64; p < 0.0001) and mortality of the total cohort (adjusted hazard ratios 1.41, 95% CI 1.29–1.55; p < 0.0001), AHD cohort (1.38, 1.24–1.54; p < 0.0001), and SIS cohort (1.49, 1.23–1.81; p < 0.0001). A high prevalence of AHD/SIS was a severe phenomenon that caused high mortality in rural areas. A regional point-of-care strategy targeting AHD/SIS detection and management is essential for reducing the mortality risk. [ABSTRACT FROM AUTHOR]

Those with self-inflicted burns are a small but consistent group among burn patients, with large injuries and conflicting findings regarding their in-hospital mortality. Overall, burn survivors have a shorter life expectancy, as compared with national controls, but long-term mortality after self-inflicted burns is understudied. The aim of this retrospective study was to investigate possible differences in long-term mortality among survivors after self-inflicted and accidental burns. All adult patients with burns admitted at the Linköping Burn Centre and discharged alive between 2000 and 2017 were included, and end of follow up was April 26, 2021. Those with unknown survival status at that time were excluded. A Cox proportional hazards regression model, adjusted for age and sex, was used to analyse long term mortality. Among the 930 patients included in this study, 37 had self-inflicted burns. Overall, median follow up period was 8.8 years and crude mortality was 24.7%. After adjustment for age and sex, self-inflicted burns were independently associated with long-term mortality, Hazard Ratio= 2.08 (95% CI 1.13–3.83). Post hoc analysis showed that the effect was most pronounced during the first years after discharge although it was noticeable over the whole study period. Long-term risk of mortality after discharge from a burn centre was higher in patients with self-inflicted burns than in patients with accidental burns. The effect was noticeable over the whole study period although it was most pronounced during the first years after discharge. • Patients with self-inflicted burns have more severe burns than those with accidental burns. • Patients with self-inflicted burns have higher risk to die after discharge than accidental burns. • The risk to die is higher during the first years after discharge.

A sepsis surveillance method using electronic health records is increasingly used to describe the epidemiology of adult sepsis. However, its application in pediatric populations has been limited, and real-world epidemiology of pediatric sepsis remains unknown. We aimed to determine whether this surveillance method could identify children with sepsis at high-risk of mortality. From a nationwide inpatient database in Japan, we included children who underwent blood culture and received antimicrobials for ≥ 4 days between 2014 and 2021. We stratified these children into those with sepsis or without sepsis by the presence of organ dysfunction. We evaluated the discrimination for in-hospital mortality by the sepsis diagnosis and the number of organ dysfunction. Among 6553 eligible children, in-hospital mortality was 7.2 % in 875 children with sepsis and 0.2 % in 5678 children without sepsis. Sepsis diagnosis discriminated in-hospital mortality with a sensitivity of 0.84 and a specificity of 0.87. The area under the curve for mortality based on the number of organ dysfunction was 0.88 (95 % confidence interval:0.84 to 0.93). In-hospital mortality incrementally increased with the number of organ dysfunction; zero, 0.2 %; one, 3.4 %; two, 12.7 %; three, 20.9 %; four, 33.3 %; and five, 50.0 %. The surveillance method effectively identified children with sepsis with high-risk of mortality and demonstrated strong discrimination of mortality. [ABSTRACT FROM AUTHOR]

The cusp overlap technique has standardized implantation for self-expanding valves with the goal of achieving more consistent implantation depths and lowering permanent pacemaker (PPM) implantation rates. We retrospectively compared short-term outcomes in patients undergoing transcatheter aortic valve replacement (TAVR) with a self-expanding valve implanted using the cusp overlap technique vs. the traditional coplanar technique in a large tertiary referral center. We conducted a retrospective study among PPM-naïve patients who underwent TAVR using the CoreValve Evolut PRO/PRO+. We compared in-hospital PPM rates in patients who underwent TAVR using the cusp overlap technique vs. the coplanar technique. Additional outcomes included in-hospital all-cause mortality, stroke, major vascular complications, annular rupture, and >mild paravalvular leak. Furthermore, we compared outcomes over time to see whether there was evidence of a learning curve. Of the 528 patients included, 270 underwent TAVR using the coplanar technique and 258 underwent TAVR using the cusp overlap technique. The rate of new PPM implantation did not differ between cohorts (17.0 % vs. 16.7 %; p = 0.910). Additionally, rates of in-hospital all-cause mortality (0.0 % vs. 0.4 %; p = 0.328), stroke (3.7 % vs. 1.6 %; p = 0.124), major vascular complications (0.7 % vs. 1.2 %; p = 0.617), annular rupture (0.4 % vs. 0.0 %; p = 0.328) and >mild paravalvular leak (0.0 % vs. 0.4 %; p = 0.444) were similar. Our secondary analysis did not identify any evidence of a learning curve. The cusp overlap technique may not yield a reduction in PPM rates when compared with the coplanar technique. Other confounders should be explored to further minimize in-hospital PPM rates. In-hospital outcomes.

Some state veterans homes (SVHs) received media attention in the wake of the COVID-19 pandemic because of allegations of poor infection control and excess mortality. However, little research has investigated how these facilities differ from community nursing homes (CNHs) and what the geographical trends of these infection and mortality differences are. We aimed to test (1) whether infection was overall lower in SVHs than CNHs, (2) whether mortality was overall lower in SVHs than CNHs, as well as the geographic distribution of nursing home infection and mortality across the United States. Retrospective nationwide cohort study. Skilled nursing facilities in the United States from May 2020 to July 2022 during the COVID-19 pandemic. Using multilevel negative binomial regression, we modeled COVID-19 infection and mortality rates in skilled nursing homes, testing for overall SVH differences from May 2020 to July 2022, placing random effects on counties to calculate adjusted county-level infection and mortality rates. SVHs experienced 18% fewer cases but 25% more deaths overall compared with CNHs. Counties with the highest levels of facility infection, including counties with SVHs, were situated mainly in Midwestern, Atlantic, and Southern states, with the majority of counties with low infection levels in Central and Western states. Counties with the highest levels of facility mortality emerged in Rust Belt and Midwestern states down to Southern states, with the lowest levels of county-level mortality, particularly among counties containing SVHs, occurring westward to Central and Western states. SVHs experienced lower infection levels but higher mortality levels than CNHs, and fewer extremely high infection and mortality rates in counties containing SVHs despite higher mortality risk in SVHs, calling attention to unobserved facility-level differences such as gender and age distributions and future research opportunities using more granular geographical aggregations to better understand facility-level SVH risk within the broader neighborhood context.

Solid benign liver lesions (BLL) are increasingly discovered, but clear indications for surgical treatment are often lacking. Concomitantly, laparoscopic liver surgery is increasingly performed. The aim of this study was to assess if the availability of laparoscopic surgery has had an impact on the characteristics and perioperative outcomes of patients with BLL. This is a retrospective international multicenter cohort study, including patients undergoing a laparoscopic or open liver resection for BLL from 19 centers in eight countries. Patients were divided according to the time period in which they underwent surgery (2008–2013, 2014–2016, and 2017–2019). Unadjusted and risk-adjusted (using logistic regression) time-trend analyses were performed. The primary outcome was textbook outcome (TOLS), defined as the absence of intraoperative incidents ≥ grade 2, bile leak ≥ grade B, severe complications, readmission and 90-day or in-hospital mortality, with the absence of a prolonged length of stay added to define TOLS+. In the complete dataset comprised of patients that underwent liver surgery for all indications, the proportion of patients undergoing liver surgery for benign disease remained stable (12.6% in the first time period, 11.9% in the second time period and 12.1% in the last time period, p = 0.454). Overall, 845 patients undergoing a liver resection for BLL in the first (n = 374), second (n = 258) or third time period (n = 213) were included. The rates of ASA-scores≥3 (9.9%–16%,p < 0.001), laparoscopic surgery (57.8%–77%,p < 0.001), and Pringle maneuver use (33.2%–47.2%,p = 0.001) increased, whereas the length of stay decreased (5 to 4 days,p < 0.001). There were no significant changes in the TOLS rate (86.6%–81.3%,p = 0.151), while the TOLS + rate increased from 41.7% to 58.7% (p < 0.001). The latter result was confirmed in the risk-adjusted analyses (aOR 1.849,p = 0.004). The surgical treatment of BLL has evolved with an increased implementation of the laparoscopic approach and a decreased length of stay. This evolution was paralleled by stable TOLS rates above 80% and an increase in the TOLS + rate. [ABSTRACT FROM AUTHOR]

Patient- and hospital-level factors associated with outcomes following pancreatoduodenectomy (PD) are well established. However, despite theoretical disruption in hepatopetal flow, the impact of cirrhosis on in-hospital mortality following PD is not well-studied. The objective of this study was to evaluate in-hospital mortality, length of stay (LOS), and post-discharge disposition in patients with cirrhosis undergoing PD. A retrospective analysis of the National Inpatient Sample (January 2002–August 2015) was conducted identifying patients undergoing PD. Using previously validated ICD-9-CM codes, patients were stratified into presence and absence of cirrhosis. Factors associated with in-hospital mortality following PD were analyzed adjusting for patient- and hospital-level factors. Following PD were analyzed after adjusting for patient- and hospital-level factors. In 16,344 patients that underwent PD, 203 (1.2 %) patients had underlying cirrhosis prior to resection. Overall in-hospital mortality following PD was significantly worse in the cirrhosis cohort (11.3 % vs. 3.6 %, p < 0.001). Patients with underlying cirrhosis were less likely to be discharged home (73.9 % vs. 83.2 %, p < 0.001) and had a longer median LOS (12.0 vs. 10.0 days, p = 0.001). The presence of underlying cirrhosis is associated with increased in-hospital mortality, longer LOS, and decreased likelihood of home discharge following PD. Given the prohibitive risks, PD should not be performed in patients with underlying cirrhosis. [ABSTRACT FROM AUTHOR]

Acute pancreatitis (AP) is a significant gastrointestinal cause of hospitalization with increasing incidence. Risk stratification is crucial for determining AP outcomes, but the association between frailty and AP outcomes is poorly understood. Moreover, age disparities in severity indices for AP complicate risk assessment. This study investigates frailty's impact on local and systemic complications in AP, readmission rates, and healthcare resource utilization. Using the National Readmission Database from 2016 to 2019, we identified adult AP patients and assessed frailty using the Frailty Risk Score. Our analysis included local and systemic complications, resource utilization, readmission rates, procedures performed, and hospitalization outcomes. Multivariate regression was employed, and statistical significance was set at P < 0.05 using Stata version 14.2. Among 1,134,738 AP patients, 6.94 % (78,750) were classified as frail, with a mean age of 63.42 years and 49.71 % being female. Frail patients experienced higher rates of local complications (e.g., pseudocyst, acute pancreatic necrosis, walled-off necrosis) and systemic complications (e.g., pleural effusion, acute respiratory distress syndrome, sepsis, abdominal compartment syndrome) compared to non-frail patients. Frailty was associated with increased readmission rates and served as an independent predictor of readmission. Frail patients had higher inpatient mortality (7.11 % vs. 1.60 %), longer hospital stays, and greater hospitalization costs. Frailty in AP patients is linked to elevated rates of local and systemic complications, increased mortality, and higher healthcare costs. Assessing frailty is crucial in AP management as it provides a valuable tool for risk stratification and identifying high-risk patients, thereby improving overall outcomes. [ABSTRACT FROM AUTHOR]

Contemporary care patterns/outcomes in high-risk pulmonary embolism (PE) patients are unknown. This study sought to characterize the management of high-risk PE patients and identify factors associated with poor outcomes. A retrospective analysis of the PERT (Pulmonary Embolism Response Team) Consortium Registry was performed. Patients presenting with intermediate-risk PE, high-risk PE, and catastrophic PE (those with hemodynamic collapse) were identified. Patient characteristics were compared with chi-square testing for categorical covariates and Student's t -test for continuous covariates. Multivariable logistic regression was used to assess associations between clinical characteristics and outcomes in the high-risk population. Of 5,790 registry patients, 2,976 presented with intermediate-risk PE and 1,442 with high-risk PE. High-risk PE patients were more frequently treated with advanced therapies than intermediate-risk PE patients (41.9% vs 30.2%; P < 0.001). In-hospital mortality (20.6% vs 3.7%; P < 0.001) and major bleeding (10.5% vs. 3.5%; P < 0.001) were more common in high-risk PE. Multivariable regression analysis demonstrated vasopressor use (OR: 4.56; 95% CI: 3.27-6.38; P < 0.01), extracorporeal membrane oxygenation use (OR: 2.86; 95% CI: 1.12-7.30; P = 0.03), identified clot-in-transit (OR: 2.26; 95% CI: 1.13-4.52; P = 0.02), and malignancy (OR: = 1.70; 95% CI: 1.13-2.56; P = 0.01) as factors associated with in-hospital mortality. Catastrophic PE patients (n = 197 [13.7% of high-risk PE patients]) had higher in-hospital mortality (42.1% vs 17.2%; P < 0.001) than those presenting with noncatastrophic high-risk PE. Extracorporeal membrane oxygenation (13.3% vs. 4.8% P < 0.001) and systemic thrombolysis (25% vs 11.3%; P < 0.001) were used more commonly in catastrophic PE. In the largest analysis of high-risk PE patients to date, mortality rates were high with the worst outcomes among patients with hemodynamic collapse. [Display omitted] [ABSTRACT FROM AUTHOR]

Prognosis following cerebral venous thrombosis (CVT) is more favorable than other stroke types, but longer-term literature is limited, and trends over time are under-explored. Using administrative data, we examined factors associated with mortality in the inpatient setting, at 30 days and at one year following hospital discharge among a large consecutive cohort of Canadian patients with CVT. CVT patients from British Columbia (BC), Canada from 2000 to 2017 were identified using ICD diagnosis codes from the BC subset of the Canadian Institute for Health Information's Discharge Abstract Database. Logistic regression was used to investigate factors associated with inpatient mortality and survival analysis with Cox regression was used to explore factors associated with mortality at 30 days and one year. Of 554 incident CVT patients identified, 508 (92 %) survived their index admission. Older age (OR 1.04, 95 % CI 1.03–1.06, p < 0.01) and the presence of seizures (OR 2.31, 95 % CI 1.08–4.94, p = 0.03) or intracranial bleeding (OR 2.28, 95 % CI 1.08–4.85, p = 0.03) were associated with increased odds of inpatient mortality. Mortality after hospital discharge was 3.0 % at 30 days and 9.4 % at one year. Older age (HR 1.05, 95 % CI 1.02–1.08, p < 0.01 at 30 days; HR 1.05, 95 % CI 1.04–1.07, p < 0.01 at 1 year) and having recent or active malignancy (HR 4.17, 95 % CI 1.51–11.52, p < 0.01 at 30 days; HR 4.60, 95 % CI 2.60–8.11, p < 0.01 at 1 year) were significantly associated with higher risks of mortality at 30 days and one year after discharge. There were decreases in inpatient mortality over the study period, but this was offset by higher mortality within 30 days after discharge in the later study epochs. Among patients discharged with a diagnosis of CVT, one-year mortality was high at 9.4 %. Older age and a history of cancer were associated with higher mortality after discharge. • Reported mortality rates in cerebral venous thrombosis (CVT) have been variable. • We report mortality in an inclusive Canadian population based CVT cohort. • The 8.3 % inpatient and 17 % one-year mortality are higher than previously reported. • Age and CVT presentation (hemorrhage/seizure) informed inpatient mortality risk. • Age and malignancy status informed mortality risk after discharge.

Surgery performed at night and on weekends is thought to be associated with increased complications. However, the impact of time of day on outcomes has not been studied within cranial neurosurgery. We aim to determine if there are differences in outcomes for cranial neurosurgery performed after hours (AH) compared with during hours (DH). We performed a single-center retrospective study of cranial neurosurgery patients who underwent emergent surgery from January 2015 through December 2019. Surgery was considered DH if the incision occurred between 8 am and 5 pm Monday through Friday. We assessed outcome measures for differences between operations performed DH or AH. Three-hundred and ninety-three patients (114 DH, 279 AH) underwent surgery. There was a lower rate of return to the operating room within 30 days for AH (8.6%) compared with DH (14.0%), P = 0.03, on multivariate analysis. There were no significant differences in length of operation, estimated blood loss, improvement in Glasgow Coma Scale, intensive care unit and total hospital length of stay, 30-day readmission, 30-day mortality, and in-hospital mortality for cases performed DH compared with AH. Further subgroup analyses were performed for patients who underwent immediate surgery for subdural hematomas, with no differences noted in outcomes on multivariate analysis. This study suggests that operating AH does not appear to negatively impact outcomes when compared with operating DH, in cases of cranial neurosurgical emergencies. Further study assessing the impact on elective neurosurgical cases is required. [ABSTRACT FROM AUTHOR]

Cardiogenic shock is associated with high in-hospital morbidity and mortality. Improvements in this care process could lead to better outcomes. This retrospective study of patients with cardiogenic shock compared two periods: no specific program to address cardiogenic shock and implementation of a cardiogenic shock program. This program included the establishment of a multidisciplinary team (shock team), early alert to the transplant hospital, initiation of a ventricular assist extracorporeal membrane oxygenation (ECMO) program, and extension of continuous care by acute cardiovascular care specialists. The primary objective was to analyse whether there were differences between in-hospital mortality and mortality during follow-up. Predictors of in-hospital mortality were examined as a secondary objective. A total of 139 patients were enrolled: 69 of them in the previous period and 70 in the cardiogenic shock program period. There was a significant reduction in in-hospital mortality (55.1% vs 37.1%; p=0.03) and mortality during follow-up (62.7% vs 44.6%; p=0.03) in the second period. Diabetes mellitus, ejection fraction, out-of-hospital cardiac arrest, and implementation of the cardiogenic shock program were independent predictors of in-hospital mortality. The implementation of a comprehensive cardiogenic shock program in a non-transplanting hospital improved in-hospital and follow-up mortality of patients in cardiogenic shock. [ABSTRACT FROM AUTHOR]
