Oral hygiene care is important for ventilator-associated pneumonia prevention. However, the optimal oral hygiene care approach remains unclear. A network meta-analysis was conducted to compare the efficacy of various oral hygiene care methods for ventilator-associated pneumonia prevention in critically ill patients, and the methods were ranked. A literature search of three representative databases was conducted. We only analyzed parallel randomized controlled trials conducted to analyze the use antiseptics or toothbrushes in oral hygiene care for adult patients undergoing invasive mechanical ventilation in the intensive care unit. The outcome measure was the incidence of ventilator-associated pneumonia. Bias risk was assessed using the Cochrane Risk of Bias 2 tool, and the confidence in the evidence was evaluated using the CINeMA approach. Statistical analyses were performed using R 4.2.0., GeMTC package, and JAGS 4.3.1. The review protocol was registered in PROSPERO (registration number: CRD42022333270). Thirteen randomized controlled trials were included in the qualitative synthesis and twelve randomized controlled trials (2395 participants) were included in the network meta-analysis. Over 50% of the included studies were conducted in medical-surgical intensive care units. Ten treatments were analyzed and 12 pairwise comparisons were conducted in the 12 included studies. Analysis using surface under the cumulative ranking curves revealed that brushing combined with chlorhexidine 0.12% was most likely the optimal intervention for preventing ventilator-associated pneumonia (88.4%), followed by the use of chlorhexidine 0.12% alone (76.1%), and brushing alone (73.2%). Oral hygiene care methods that included brushing had high rankings. In conclusion, brushing combined with chlorhexidine 0.12% may be an effective intervention for preventing ventilator-associated pneumonia in critically ill patients. Furthermore, brushing may be the optimal oral hygiene care method for preventing ventilator-associated pneumonia in the intensive care unit. Further research is needed to verify these findings as the CINeMA confidence rate was low for each comparison., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Yamakita et al.

Endotracheal intubation is a vital means of saving critically ill patients. However, the inserted catheter often causes tissue damage and the formation of tenacious biofilms containing drug-resistant bacteria and fungi, leading to severe ventilator-associated pneumonia (VAP). Currently, the resolution of VAP is usually based on antibiotic treatment and lacks targeted prophylaxis. Here, a quaternary phosphonium salts functionalized hydrogel catheter that enhances tissue compatibility yet inhibits complex and tenacious pathogens in the catheter, thus preventing VAP is reported. By copolymerizing the quaternary phosphonium electrolyte and acrylic acid monomers, the hydrogel catheter demonstrates good shape-supporting ability, and its strength and modulus can be adjusted over a wide range to meet the needs of different ages. Moreover, it possesses good tissue compatibility, antifouling properties, stable lubrication capability, and superior hydrophilicity, which may mitigate tissue damage caused by contact. Importantly, the hydrogel catheter demonstrates potent broad-spectrum intrinsic antimicrobial activity, eradicating nearly 99% of multi-drug resistant bacteria and 80% of fungi. To validate its role in preventing VAP, the real VAP pathogenesis process is mimicked, establishing a polymicrobial infections model considering time effects. The results prove that the hydrogel catheter effectively inhibits the invasion of various drug-resistant pathogens and prevents biofilm formation., (© 2024 Wiley‐VCH GmbH.)

Background: Early identification of patients at risk of nosocomial pneumonia enables the opportunity for preventative measures, which may improve survival and reduce costs. Therefore, this study aimed to externally validate an existing prediction model (issued by Croce et al.) to predict nosocomial pneumonia in patients admitted to US level-1 trauma centers., Methods: A retrospective cohort study including patients admitted to level-1 trauma centers and registered in the TQIP, a US nationwide trauma registry, admitted between 2013-2015 and 2017-2019. The main outcome was total nosocomial pneumonia for the first period and ventilator-associated pneumonia (VAP) for the second. Model discrimination and calibration were assessed before and after recalibration., Results: The study comprised 902,231 trauma patients (N 2013-2015  ​= ​180,601; N 2017-2019  ​= ​721,630), with a median age of 52 in both periods, 64-65 ​% male, and approximately 90 ​% sustaining blunt traumatic injury. The median Injury Severity Scores were 13 (2013-2015) versus 9 (2017-2019); median Glasgow Coma Scale scores were 15. Nosocomial pneumonia incidence was 4.4 ​%, VAP incidence was 0.7 ​%. The original model demonstrated good to excellent discrimination for both periods (c-statistic 2013-2015 0.84, 95%CI 0.83-0.84; c-statistic 2017-2019 0.92, 95%CI 0.91-0.92). After recalibration, discriminatory capacity and calibration for the lower predicted probabilities improved., Conclusions: The Croce model can identify patients admitted to US level-1 trauma centers at risk of total nosocomial pneumonia and VAP. Implementing (modified) Croce models in route trauma clinical practice could guide judicious use of preventative measures and prescription of additional non-invasive preventative measures (e.g., increased monitoring, pulmonary physiotherapy) to decrease the occurrence of nosocomial pneumonia in at-risk patients., (Copyright © 2024 The Authors.

Objective: This study aimed to assess the impact of a lung-protective ventilation strategy utilizing transpulmonary driving pressure titrated positive end-expiratory pressure (PEEP) on the prognosis [mechanical ventilation duration, hospital stay, 28-day mortality rate and incidence of ventilator-associated pneumonia (VAP), survival outcome] of patients with Acute Respiratory Distress Syndrome (ARDS)., Methods: A total of 105 ARDS patients were randomly assigned to either the control group (n = 51) or the study group (n = 53). The control group received PEEP titration based on tidal volume [A tidal volume of 6 mL/kg, flow rate of 30-60 L/min, frequency of 16-20 breaths/min, constant flow rate, inspiratory-to-expiratory ratio of 1:1 to 1:1.5, and a plateau pressure ≤ 30-35 cmH 2 O. PEEP was adjusted to maintain oxygen saturation (SaO 2 ) at or above 90%, taking into account blood pressure], while the study group received PEEP titration based on transpulmonary driving pressure (Esophageal pressure was measured as a surrogate for pleural pressure using an esophageal pressure measurement catheter connected to the ventilator. Tidal volume and PEEP were adjusted based on the observed end-inspiratory and end-expiratory transpulmonary pressures, aiming to maintain a transpulmonary driving pressure below 15 cmH 2 O during mechanical ventilation. Adjustments were made 2-4 times per day). Statistical analysis and comparison were conducted on lung function indicators [oxygenation index (OI), arterial oxygen tension (PaO2), arterial carbon dioxide tension (PaCO2)] as well as other measures such as heart rate, mean arterial pressure, and central venous pressure in two groups of patients after 48 h of mechanical ventilation. The 28-day mortality rate, duration of mechanical ventilation, length of hospital stay, and ventilator-associated pneumonia (VAP) incidence were compared between the two groups. A 60-day follow-up was performed to record the survival status of the patients., Results: In the control group, the mean age was (55.55 ± 10.51) years, with 33 females and 18 males. The pre-ICU hospital stay was (32.56 ± 9.89) hours. The mean Acute Physiology and Chronic Health Evaluation (APACHE) II score was (19.08 ± 4.67), and the mean Murray Acute Lung Injury score was (4.31 ± 0.94). In the study group, the mean age was (57.33 ± 12.21) years, with 29 females and 25 males. The pre-ICU hospital stay was (33.42 ± 10.75) hours. The mean APACHE II score was (20.23 ± 5.00), and the mean Murray Acute Lung Injury score was (4.45 ± 0.88). They presented a homogeneous profile (all P > 0.05). Following intervention, significant improvements were observed in PaO 2 and OI compared to pre-intervention values. The study group exhibited significantly higher PaO 2 and OI compared to the control group, with statistically significant differences (all P < 0.05). After intervention, the study group exhibited a significant increase in PaCO2 (43.69 ± 6.71 mmHg) compared to pre-intervention levels (34.19 ± 5.39 mmHg). The study group's PaCO2 was higher than the control group (42.15 ± 7.25 mmHg), but the difference was not statistically significant (P > 0.05). There were no significant differences in hemodynamic indicators between the two groups post-intervention (all P > 0.05). The study group demonstrated significantly shorter mechanical ventilation duration and hospital stay, while 28-day mortality rate and incidence of ventilator-associated pneumonia (VAP) showed no significant differences. Kaplan-Meier survival analysis revealed a significantly better survival outcome in the study group at the 60-day follow-up (HR = 0.565, 95% CI: 0.320-0.999)., Conclusion: Lung-protective mechanical ventilation using transpulmonary driving pressure titrated PEEP effectively improves lung function, reduces mechanical ventilation duration and hospital stay, and enhances survival outcomes in patients with ARDS. However, further study is needed to facilitate the wider adoption of this approach., Competing Interests: Declarations.

Tracheostomy can reduce mechanical ventilation (MV) duration, ICU and hospital length of stay (LOS), and ventilator-associated pneumonia (VAP) risk in critically ill patients. The timing of tracheostomy in COVID-19 patients has been studied, but its impact on VAP incidence has rarely been analyzed. This study investigated tracheostomy timing's impact on VAP incidence, ventilation time, ICU and hospital LOS, and mortality in critically ill COVID-19 patients. It was conducted at the University Hospital in Wroclaw, Poland, from October 1, 2020, to June 30, 2021. Of 60 tracheostomized patients, 21 (35%) developed VAP. Early tracheostomy (≤ 13 days) resulted in 8/42 (19%) VAP cases, while late tracheostomy (> 13 days) had 13/18 (72%) VAP cases, showing a significantly lower VAP risk in the early group (p < 0.05). VAP incidence rates were 7.9 and 22.8 per 1000 patient-days for early and late groups, respectively. Early tracheostomy patients had shorter median MV duration (18 vs. 33 days, p < 0.05), ICU LOS (20 vs. 31 days, p < 0.05) and hospital LOS (25 vs. 47 days, p < 0.05). Early tracheostomy in critically ill COVID-19 patients significantly reduced VAP risk, MV duration, ICU, and hospital LOS., Competing Interests: Declarations.

Background: This Population, Intervention, Comparison, and Outcomes-guided systematic review assesses continuous lateral rotation therapy versus conventional position changes in mechanically ventilated critically ill adults, evaluating mortality, ICU length of stay (LOS), and hospital LOS as primary outcomes and respiratory function, mechanical ventilation duration, pulmonary complications, and adverse events as secondary outcomes., Methods: This systematic review follows Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria (International Prospective Register of Systematic Reviews CRD42022384258). Searches spanned databases MEDLINE/PubMed, Embase, Scopus, ScienceDirect, Cochrane, CINAHL, and Web of Science, without language or publication year restrictions. Inclusion criteria involved randomized controlled trials (RCTs) and quasi-randomized trials, comparing continuous lateral rotation therapy (intervention) with conventional position changes (control). Risk of bias and quality of evidence for RCTs were assessed using the Cochrane Collaboration and Grading of Recommendations Assessment, Development, and Evaluation tools. For the quasi-randomized trials, the Risk of Bias in Non-Randomized Studies-of Interventions tool was used., Results: In 18 studies with 1,466 participants (intervention, n = 700, 47.7%; control, n = 766, 52.2%), continuous lateral rotation therapy was predominantly used for prophylactic purposes, with protocols varying from 10-24 h/d. Meta-analysis (16 RCTs) favored continuous lateral rotation therapy for reduced mechanical ventilation duration (standardized mean difference [SMD] -0.17 [CI -0.29 to -0.04] d, P = .008) and lower nosocomial pneumonia incidence (odds ratio 0.39 [CI 0.29-0.52], P < .001). Continuous lateral rotation therapy showed no significant impact on mortality (odds ratio 1.04 [CI 0.80-1.34], P = .77), ICU LOS (SMD -0.11 [CI -0.25 to 0.02] d, P = .11), hospital LOS (SMD -0.10 [CI -0.31 to 0.11] d, P = .33), and incidence of pressure ulcers (odds ratio 0.73 [CI 0.34-1.60], P = .44)., Conclusions: Continuous lateral rotation therapy showed no significant difference in primary outcomes (mortality, ICU and hospital LOS) but revealed significant differences in secondary outcomes (consistently reduced nosocomial pneumonia, with a minor effect on mechanical ventilation duration), supported by moderate certainty. Very low certainty for other outcomes highlights the need for current studies in diverse clinical settings and protocols to assess continuous lateral rotation therapy effectiveness., Competing Interests: The authors have disclosed no conflicts of interest., (Copyright © 2024 by Daedalus Enterprises.)

Background: Ventilator-associated pneumonia (VAP) is the most common nosocomial infection in intensive care units (ICUs) and is a common cause of morbidity and mortality in intensive care patients. Previous studies show that insufficient knowledge and compliance barriers among nurses affect pneumonia. There have been no investigations into intensive care nurses' knowledge and compliance barriers to evidence-based guidelines (EBGs) for VAP prevention in county-level hospitals in China., Aim: To explore adult ICU nurses' knowledge and compliance barriers to EBGs for preventing VAP in county-level hospitals in Hunan Province, China, examine the correlation between knowledge and compliance barriers, and analyse associated factors., Study Design: A cross-sectional electronic survey was conducted to focus on nurses' knowledge of and compliance barriers to EBGs for preventing VAP., Results: A total of 386 valid questionnaires were collected, with a response rate of 97.47% (386/396 = 97.47%). The median scores for nurses' knowledge (out of 9) and compliance barriers (out of 8) to EBGs for preventing VAP were 7 (interquartile range: 5-8) and 3 (interquartile range: 2-4), respectively. Knowledge was negatively associated with compliance barriers (r = -0.437, p < .01). The results of the multiple linear regression analysis showed that hospital level, age, nurses' attendance at VAP training and years of experience in ICUs were related to the level of knowledge. Nurses' attendance at VAP training, age and years of experience in ICUs were associated with the level of compliance barriers., Conclusions: Intensive care nurses have satisfactory knowledge of EBGs for preventing VAP, but compliance barriers can be reduced. Better knowledge helps reduce the barriers to compliance among nurses., Relevance to Clinical Practice: Nurse managers and nurse educators are suggested to examine nurses' knowledge and compliance barriers to EBGs for preventing VAP, develop personalized training plans, promote continuous education based on the latest EBGs and raise the nurse-patient ratio reasonably., (© 2024 British Association of Critical Care Nurses.)

Background: Ventilator-associated pneumonia (VAP) constitutes a considerable challenge for patients in intensive care units (ICUs) and necessitates the development of effective preventive strategies. This study aimed to evaluate the clinical efficacy of inhaled antibiotics for preventing VAP., Methods: PubMed, Embase, and ClinicalTrials.gov were searched until 21 January 2024. Randomized controlled trials investigating the clinical efficacy of inhaled antibiotics for VAP prevention were included., Results: Seven randomized controlled trials, involving 1465 patients, of whom 734 were classified as the study group receiving inhaled antibiotics and 731 as the control group receiving placebo were included in this meta-analysis. Overall, the occurrence of VAP was significantly lower in the study group than in the control group (risk ratio, 0.69; 95% confidence interval [CI], 0.51-0.92). However, there were no significant differences in mortality (risk ratio, 0.90; 95% CI, 0.74-1.09), length of stay in ICU (mean difference [MD], 0.10 d; 95% CI, -0.91 to 1.1), and hospital (MD, 0.30 d; 95% CI, -1.82 to 2.43), and mechanical ventilation duration (MD, 0.45 d; 95% CI, -0.45 to 1.35) between groups., Conclusions: Inhaled antibiotics hold promise for mitigating the risk of VAP among critically ill patients. However, their impact on mortality, length of stay in ICU and hospital, and mechanical ventilation duration was not statistically significant., Competing Interests: Declaration of competing interests All authors affirm that no conflict of interest exists., (Copyright © 2024 Elsevier Ltd and International Society of Antimicrobial Chemotherapy.

Background: Ventilator-associated pneumonia (VAP) is a significant concern in low-middle-income countries (LMICs), where the burden of hospital-acquired infections is high, and resources are low. Evidence-based guidelines exist for preventing VAP; however, these guidelines may not be adequately utilized in intensive care units of LMICs., Aim: This scoping review examined the literature regarding the use of nursing care bundles for VAP prevention in LMICs, to understand the knowledge, practice and compliance of nurses to these guidelines, as well as the barriers preventing the implementation of these guidelines., Study Design: The review was conducted using Arksey and O'Malley's (2005) five-stage framework and the PRISMA-ScR guidelines guided reporting. Searches were performed across six databases: CINAHL, Medline, Embase, Global Health, Scopus and Cochrane, resulting in 401 studies., Results: After screening all studies against the eligibility criteria, 21 studies were included in the data extraction stage of the review. Across the studies, the knowledge and compliance of nurses regarding VAP prevention were reported as low to moderate. Several factors, ranging from insufficient knowledge to a lack of adequate guidelines for VAP management, served as contributing factors. Multiple barriers prevented nurses from adhering to VAP guidelines effectively, including a lack of audit/surveillance, absence of infection prevention and control (IPC) teams and inadequate training opportunities., Conclusions: This review highlights the need for adequate quality improvement procedures and more efforts to conduct and translate research into practice in intensive care units in LMIC., Relevance to Clinical Practice: IPC practices are vital to protect vulnerable patients in intensive care units from developing infections and complications that worsen their prognosis. Critical care nurses should be trained and reinforced to practice effective bundle care to prevent VAP., (© 2024 The Authors.

Background: In South Korea, various quality assessments have been introduced to improve the quality of care; as such, the overall level of quality of medical institutions has improved. However, gaps still exist between institutions., Aim: To evaluate the impact of quality management efforts of medical institutions on securing medical staff and healthcare-associated infections in intensive care units (ICUs)., Methods: This study used data from the second and third ICU quality assessments conducted by the Health Insurance Review and Assessment Service, which included 265 hospitals and 39,096 inpatients. The continuous quality improvement efforts of medical institutions were measured according to changes in their grade based on quality assessment results. In addition, healthcare-associated infection rates were measured, including rates for ventilator-associated pneumonia and catheter-associated infections. The incidence rate ratio (IRR) was calculated using generalized estimating equation Poisson regression models that included hospital and patient characteristics., Results: Healthcare-associated infections occurred in approximately 2% of patients using ventilators or catheters. Ventilator-associated pneumonia increased significantly in institutions with a decline in grade [IRR 2.038, 95% confidence interval (CI) 1.426-2.915]. In institutions with an improvement in grade, infections associated with central venous catheters (IRR 0.484, 95% CI 0.330-0.711) and urinary catheters (IRR 0.587, 95% CI 0.398-0.866) decreased., Conclusions: Although quality assessment has been introduced in ICUs in South Korea, some gaps remain between medical institutions. Differences in securing medical resources through the quality management efforts of medical institutions were observed, and the infection rate was low in hospitals with high-quality management and high in hospitals with low-quality management., (Copyright © 2024 The Healthcare Infection Society.

Background: Ventilator-associated pneumonia (VAP) is one of the common complications in patients in the intensive care unit. Abdominal massage may prevent the development of VAP by reducing residual gastric volume in enterally fed patients., Aim: The purpose of this study is to review the literature on randomized controlled and quasi-experimental studies evaluating the effectiveness of abdominal massage in preventing VAP., Methods: The PRISMA-P (Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols) criteria were taken as the basis for creating the protocol of the systematic review and writing the article. The systematic review was performed using the Google Scholar, PubMed, Web of Science, Scopus, CINAHL and Cochrane Library databases from December 2023 to January 2024. Studies were selected by determining inclusion and exclusion criteria according to the PICOS method. The studies were evaluated using the Joanna Briggs Institute (JBI) tool for quality assessment., Results: Three randomized controlled and one quasi-experimental study with a total of 225 participants met the inclusion criteria. The four studies conducted on patients in the intensive care unit showed that abdominal massage reduced VAP. The studies reported no adverse effects of abdominal massage., Conclusion: Promising evidence was found for the effect of abdominal massage in preventing VAP. However, scientific studies with larger samples, of higher quality, and using randomized controls and blinding methods are needed to evaluate the unknown dimensions of abdominal massage and determine its beneficial effects on patients., Relevance to Clinical Practice: Several non-pharmacological methods may decrease VAP incidence and mortality. Abdominal massage may decrease VAP incidence and mortality., (© 2024 British Association of Critical Care Nurses.)

Objective: This study aimed to investigate the impact of optimizing the subglottic suction and aspiration sequence on ventilator-associated pneumonia (VAP) incidence., Methods: A total of 108 patients undergoing transcatheter orotracheal intubation with subglottic secretion drainage (SSD) and mechanical ventilation were selected from the Department of Critical Care Medicine in our hospital between September 2021 and March 2023. The patients were randomly assigned to either the observation group or the control group (54 cases each) using a random number method. In the control group, patients underwent manual airway suction followed by subglottic suction with -100 mmHg pressure. In the observation group, subglottic suction with -100 mmHg pressure was performed first, followed by manual airway suction. The comparative analysis included blood gas parameters, sputum suction effectiveness, VAP occurrence, 28-day morbidity and mortality rates, tracheal secretion culture results, and the workload of nurses., Results: The observation group exhibited significantly shorter tape replacement time, sputum suction time, and number of suctions, along with a longer suction interval compared to the control group (P < 0.05). Post-suctioning, the observation group demonstrated improved blood gas function and a lower incidence of VAP (P < .05). No significant difference in adverse reaction incidence was observed between the two groups (P > .05); however, the Kolcaba score was higher in the observation group (P < .05)., Conclusions: Pre-endotracheal intubation oral and nasal sputum suctioning proves effective in reducing the risk of VAP, lessening the workload of nurses, and enhancing the comfort of sputum suctioning.

Background: Nosocomial infections pose a global health threat, with Ventilator-Associated Pneumonia (VAP) emerging as a prominent hospital-acquired infection, particularly in intensive care units (ICU).VAP is the commonest form of pneumonia in ICUs, contributing significantly to morbidity and mortality rates, which can reach around 30%. Despite the substantial impact of VAP on healthcare, there is a lack of data on adherence to VAP prevention protocols in our hospital. Consequently, this study aims to assess the adherence to ventilator-associated pneumonia care bundles in critical care units at a comprehensive specialized hospital in northwest Ethiopia., Methods: A hospital-based prospective observational study was conducted from July 3, 2022, to January 7, 2024. All adult patients who were on mechanical ventilators for more than 48 h during the study period were included. Data were collected using the Institute of Healthcare Improvement VAP prevention standards as checklists via direct observation and chart review. The data were entered and analyzed using SPSS version 20., Results: A total of 300 surgical and medical ICU patients were observed. Among the patients, 66.3% were from the medical ICU. In terms of admission reasons, 22.3%, 15.7% and, 12% were attributed to infections excluding respiratory origin, respiratory disorders, and other causes, respectively. The rate of compliance with all components of the bundle was 70%. A 100% adherence rate was observed for the prophylaxis for peptic ulcer and deep vein thrombosis (DVT). The lowest adherence rate was observed in the practice of oral hygiene with 0.5% chlorhexidine solution (0%) followed by humidification with heat and moisture exchangers (23.3%). Endotracheal tube cuff pressure measurement and use of endotracheal tubes with subglottic suction were not applicable., Conclusion: The study revealed suboptimal compliance with the VAP care bundle, indicating unsatisfactory overall practice. Specific attention is warranted for subglottic suction, cuff pressure measurement, humidification, oral care with chlorhexidine, and sedation vacation., (© 2024. The Author(s).)

Caring for patients in the intensive care unit (ICU) creates competing priorities of interventions for nurses and other health care providers. Oral care might be prioritized lower; however, its neglect may lead to sequelae such as extended time in the ICU, nosocomial diseases most notably ventilator-associated pneumonia (VAP), or oral problems. Safe patient care depends on effective and efficient oral care. The aim of this study was to lower the incidence of VAP and maintain oral health through implementing an "oral care bundle" for mechanically ventilated (MV) patients. Using a quasi-experimental design, we divided 82 adult MV patients in the ICUs of a university-based hospital in Egypt into a control group (n = 41) that received the standard of care and a bundle group (n = 41) that received an "oral care bundle." The results of the study reported a significantly lower incidence of VAP in the intervention group (P = .015). It can be concluded that there is a significant relationship between receiving an oral care bundle and improved oral health and a reduction in the VAP rate among MV patients. This highlights the need to incorporate the oral care bundle in the daily nursing care for MV patients., Competing Interests: The author has no conflicts of interest in the manuscript, including financial, consultant, institutional, and other relationships that might lead to bias or a conflict of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Ventilator-associated pneumonia (VAP) is one of the most common causes of nosocomial infections. The aim of this study was to evaluate the antimicrobial and anti-biofilm activity of an in-house low-cost tracheostomy tube impregnated with chlorhexidine and violet crystal. The impregnated tracheostomy tubes demonstrated antimicrobial activity, including for multidrug-resistant bacteria. Fourteen patients were evaluated. During ventilation, VAP occurred in one patient in the coated group and in three patients in the control group (p=0.28). A reduction of biofilm cells was observed. This study provides preliminary evidence to support that the antiseptic impregnation of a tracheostomy tube provides significant antimicrobial activity., (Copyright © 2024 Asociación Argentina de Microbiología.

Objectives: To assess the effects of antibiotics delivered via the respiratory tract in preventing ventilator-associated pneumonia (VAP)., Data Sources: We searched PubMed, Scopus, the Cochrane Library, and ClinicalTrials.gov for studies published in English up to October 25, 2023., Study Selection: Adult patients with mechanical ventilation of over 48 h and receiving inhaled or instilled antibiotics (with control group) to prevent VAP were included., Data Extraction: Two independent groups screened studies, extracted the data, and assessed the risk of bias. The Grading of Recommendations Assessment, Development, and Evaluation approach was used to assess the certainty/quality of the evidence. Results of a random-effects model were reported for overall and predefined subgroup meta-analyses. The analysis was primarily conducted on randomized controlled trials, and observational studies were used for sensitivity analyses., Data Synthesis: Seven RCTs with 1445 patients were included, of which six involving 1283 patients used nebulizers to deliver antibiotics. No obvious risk of bias was found among the included RCTs for the primary outcome. Compared with control group, prophylactic antibiotics delivery via the respiratory tract significantly reduced the risk of VAP (risk ratio [RR], 0.69 [95% CI, 0.53-0.89]), particularly in subgroups where aminoglycosides (RR, 0.67 [0.47-0.97]) or nebulization (RR, 0.64 [0.49-0.83]) were used as opposed to other antibiotics (ceftazidime and colistin) or intratracheal instillation. No significant differences were observed in mortality, mechanical ventilation duration, ICU and hospital length of stay, duration of systemic antibiotics, need for tracheostomy, and adverse events between the two groups. Results were confirmed in sensitivity analyses., Conclusions: In adult patients with mechanical ventilation for over 48 h, prophylactic antibiotics delivered via the respiratory tract reduced the risk of VAP, particularly for those treated with nebulized aminoglycosides., Competing Interests: Dr. Li’s institution received funding from the Rice Foundation, the American Association for Respiratory Care, Aerogen Ltd, and Fisher & Paykel Healthcare Ltd; she received speaker fees from Fisher & Paykel Healthcare Ltd, the American Association for Respiratory Care, Aerogen Ltd, Heyer Ltd, and Vincent Ltd.

Introduction: Surgical stabilization of rib fractures (SSRF) has been associated with lower rates of mortality and fewer respiratory complications. This study sought to evaluate the association between SSRF timing and patient outcomes., Methods: This retrospective analysis included patients aged ≥45 y who underwent SSRF in the Trauma Quality Improvement Program database from 2016 to 2020. Primary outcome was incidence of ventilator-assisted pneumonia (VAP). Secondary outcomes included acute respiratory distress syndrome (ARDS), unplanned endotracheal intubation, in-hospital mortality, failure to rescue (FTR) after all major complications, and FTR after severe respiratory complications. Logistic regression models of outcomes on timing to SSRF were fit while controlling for age, gender, body mass index, injury severity score, flail chest, chronic obstructive pulmonary disease, congestive heart failure, and smoking., Results: Among 4667 patients who received SSRF, average time to SSRF was 4.6 ± 3.2 d. Each additional day to SSRF was associated with increased odds of VAP (odds ratio [OR] 1.07, confidence interval [CI] 1.03-1.11) and intubation (OR 1.10, CI 1.08-1.13). A longer time to SSRF was associated with increased odds of ARDS (OR 1.10, CI 1.05-1.15), while no significant association was observed for in-hospital mortality (OR 0.99, CI 0.93-1.04). A longer time to SSRF was associated with decreased odds of FTR after a major complication (OR 0.90, CI 0.83-0.97) and respiratory complications (OR 0.87, CI 0.78-0.96)., Conclusions: For each day that SSRF is delayed, increased odds of VAP, intubation, and ARDS were observed. Prompt intervention is crucial for preventing these complications and improving our ability to rescue patients., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Objective: To describe the practice of ventilator-associated pneumonia (VAP) prevention and control through the incremental introduction of prevention strategies and assess the effect on VAP incidence., Design: Historical observational surveillance study conducted over 13 years., Setting: A 12-bed adult intensive care unit (ICU) in a general hospital in Belgium., Participants: Patients admitted between 2007 and 2019, with ICU stays of ≥48 h., Interventions: Incremental introduction of VAP preventive measures from 2008, including head-of-bed elevation, cuff pressure control, endotracheal tubes with tapered cuffs, subglottic secretion drainage, chlorhexidine oral care, and daily sedation assessment., Measurements and Main Results: A significant decline in VAP incidence density rates was observed, from 18.3 to 2.6 cases per 1000 ventilator days from the baseline to the final period., Conclusions: Systematic implementation of VAP preventive measures significantly reduced VAP incidence.

Objective: The relationship between ventilator-associated events (VAE) and microaspiration in intubated patients has not be studied. The objective of this study was to evaluate the relationship between abundant microaspiration of oropharyngeal secretions or gastric contents and the incidence of VAE., Patients and Methods: This was a post hoc analysis of the BESTCUFF study, which was a multicenter, cluster randomized, cross-over, controlled, open-label trial in adult patients ventilated for over 48 h. All tracheal aspirates were sampled for 48 h following enrollment, with quantitative measurement of pepsin and alpha-amylase. VAE were identified using National Healthcare Safety Network criteria, based on PEEP or FiO 2 variations compared to stable parameters in previous days. The primary objective was to assess the relationship between abundant global microaspiration and the incidence of VAE, adjusted for pre-specified confounding factors (sex, SAPS II score and Glasgow coma scale)., Results: 261 patients were included, of which 31 (11.9%) developed VAE, with an overall median age of 65 (interquartile range 52-74), a majority of male patients (164, 62.8%), a median SAPS II score of 50 [40-61], a median SOFA score of 8 [5-11], and acute respiratory failure as main reason for ICU admission (117, 44.8%).The incidence of VAE was not significantly associated with abundant global microaspiration (adjusted cause-specific hazard ratio (cHR): 1.55 [0.46-5.17), abundant gastric microaspiration (adjusted cHR: 1.24 [0.61-2.53), or with abundant oropharyngeal microaspiration (adjusted HR: 1.07 [0.47-2.42])., Conclusions: Our results suggest no significant association between abundant global, gastric or oropharyngeal microaspiration and the incidence of VAE., Implications for Clinical Practice: This study underscores that measuring microaspiration in intubated critically ill patients might not be useful to predict the diagnosis of VAE or to evaluate interventions aiming at preventing these complications., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: SN has received lecture fees from MSD, Pfizer, Biomérieux, Medtronic, and Fisher and Paykel; he is a member of the advisory boards of Mundipharma.

Introduction: Ventilator-associated pneumonia (VAP) causes increased time of mechanical ventilation (MV), prolonged intensive care unit (ICU) stay, and a higher mortality risk. The systematic review and meta-analysis aimed to compare the efficacies between fiberoptic bronchoscopy (FOB) and general sputum suction for the prevention of VAP in patients with invasive MV., Methodology: Relevant randomized controlled trials (RCTs) were obtained via a search of PubMed, Embase, Cochrane Library, Wanfang, and CNKI databases. A random-effects model was used to pool the results if significant heterogeneity was observed. Otherwise, a fixed-effects model was used., Results: Sixteen RCTs were included. Compared to general sputum suction, sputum suction with FOB was associated with a significantly reduced risk of VAP (risk ratio [RR]: 0.56, 95% CI: 0.47 to 0.67, p < 0.001; I2 = 0%). Subgroup analyses showed that the combination of FOB-assisted sputum suction with bronchoalveolar lavage (BAL) further reduced the risk of VAP as compared to FOB-assisted sputum suction alone (p for subgroup difference = 0.04). In addition, FOB-assisted treatment was also associated with a reduced MV time (mean difference [MD]: -2.19 days, 95% CI: -2.69 to -1.68, p < 0.001; I2 = 18%), a shorter ICU stay (MD: 2.9 days, 95% CI: -3.68 to -2.13, p < 0.001; I2 = 34%), and a reduced mortality risk (RR: 0.46, 95% CI: 0.24 to 0.90, p = 0.02; I2 = 0%) in patients with invasive MV., Conclusions: FOB for sputum suction and BAL in patients with invasive MV is effective in reducing the incidence of VAP., Competing Interests: No Conflict of Interest is declared, (Copyright (c) 2024 Haowei Tang, Yuan Zhi, Jingjie Li, Qun Wang, Weijie Fan.)

Ventilator-associated pneumonia (VAP) remains one of the most common hospital-acquired infections (HAI). Considering the complicated diagnosis and the lack of effective treatment, prophylactic measures are suggested as the new standard to prevent the disease. Although VAP often manifests a polymicrobial nature, Pseudomonas aeruginosa remains one of the pathogens associated with the highest morbidity and mortality rates within these mechanically ventilated patients. In this paper, we report on the development of an antibacterial hydrogel coating using the polymyxin B (PMB) peptide to prevent bacterial adhesion to the polymeric substrate. We fully characterized the properties of the coating using atomic force microscopy (AFM), scanning electron microscopy (SEM), wettability analyses and Fourier-transform infrared (FTIR) and Raman spectroscopy. Furthermore, several biological assays confirmed the antibacterial and anti-biofilm effect of the tubing for at least 8 days against P. aeruginosa . On top of that, the produced coating is compliant with the requirements regarding cytocompatibility stated in the ISO (International Organization for Standardization) 10993 guidelines and an extended release of PMB over a period of at least 42 days was detected. In conclusion, this study serves as a foundation for peptide-releasing hydrogel formulas in the prevention of VAP.

Background: Ventilator-associated pneumonia (VAP) is the second most prevalent nosocomial infection in emergency care settings. An emerging strategy to reduce this risk involves coating endotracheal tubes (ETTs) with noble elements, leveraging the antimicrobial properties of elements such as silver, gold, and palladium. This systematic review and meta-analysis aimed to evaluate the effectiveness of noble element coatings on ETTs in reducing VAP incidence rates, mortality, duration of mechanical ventilation, and length of stay in the intensive care unit (ICU)., Methods: Adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a comprehensive search was conducted across 5 databases up to 2024. The quality of the randomized controlled trials was assessed using the updated Cochrane Risk of Bias (RoB) 2 tool. A random-effects meta-analysis was performed using RevMan 5.4 Comprehensive Meta-Analysis software. Statistical heterogeneity among the studies was evaluated using the Higgins I2 value, with P < .05 indicating statistical significance., Results: Seven randomized controlled trials from 5 countries were identified. Four studies had some concerns regarding bias, 2 had a high RoB, and 1 had a low RoB. Noble metal-coated ETTs resulted in a lower incidence of VAP compared to noncoated ETTs (relative risk, 0.76 [95% confidence interval [CI], 0.60-0.96]). However, there was no significant difference in mortality rates (relative risk, 1.06 [95% CI, 0.93-1.20]), duration of mechanical ventilation (mean difference, -0.10 [95% CI, -1.62 to 1.41]), and ICU stay (mean difference, 0.07 [95% CI, -1.98 to 2.12])., Conclusion: Noble metal-coated ETTs effectively reduce the incidence of VAP but do not significantly impact mortality rates, the duration of mechanical ventilation, or ICU stay. Therefore, these coated ETTs should be integrated into a holistic care plan addressing all aspects of patient management in emergency care settings., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Background: Mechanical ventilation is crucial for patient management in intensive care units, but it comes with complications such as pressure ulcers and ventilator-associated pneumonia (VAP). The impact of head-of-bed elevation angles on these complications remains a critical area for investigation., Methods: This systematic review and meta-analysis followed PRISMA guidelines and involved searches across PubMed, Embase, Web of Science, and Cochrane Library, conducted on September 19, 2023, with no date or language restrictions. We included randomized controlled trials that compared different head-of-bed elevation angles in adult ICU patients on mechanical ventilation. Data were extracted on study characteristics, quality assessed using the Cochrane risk of bias tool, and statistical analyses performed using chi-square tests for heterogeneity and fixed or random-effects models based on heterogeneity results., Results: Six studies met inclusion criteria out of an initial 601 articles. These studies showed minimal heterogeneity (I 2  = 0.0% for pressure ulcers, p = 0.930; and for VAP, p = 0.797), supporting the use of fixed-effect models. Results indicated that a higher elevation angle (45°) significantly increased the risk of pressure ulcers (OR = 1.95, 95% CI: 1.12-3.37, p < 0.05) and decreased the incidence of VAP compared to a lower angle (30°) (OR = 0.51, 95% CI: 0.31-0.84, p < 0.05)., Conclusions: While higher head-of-bed elevation can reduce the risk of VAP in mechanically ventilated patients, it may increase the risk of pressure ulcers. Clinical strategies should carefully balance these outcomes to optimize patient care in ICU settings., Registration: PROSPERO 2024 CRD42024570232., (© 2024. The Author(s).)

Purpose: This study aimed to evaluate whether endotracheal tubes (ETTs) with a metal coating reduce the incidence of ventilator-associated pneumonia (VAP) compared to uncoated ETTs., Methods: An extensive literature review was conducted to find studies that compared metal-coated ETT with uncoated ETT across four databases: PubMed, Embase, Cochrane Library, and Web of Science. The search parameters were set from the inception of each database until June 2024. The primary outcome measures were the rates of VAP and hospital mortality. Two independent researchers carried out the literature selection, data extraction, and quality evaluation. Data analysis was performed with RevMan 5.4.1. Furthermore, a Deeks funnel plot was used to evaluate potential publication bias in the studies included., Results: Following the screening process, five randomized controlled trials (RCTs) encompassing a total of 2157 patients were identified. In terms of the primary outcome, the VAP incidence was found to be lower in the group utilizing metal-coated ETT compared to those with uncoated ETT, demonstrating a statistically significant difference [RR = 0.71, 95% CI (0.54-0.95), P = 0.02]. No notable difference in mortality rates was observed between the two groups [RR = 1.05, 95% CI (0.86-1.27), P = 0.65]. Concerning secondary outcomes, two studies were evaluated to compare the mechanical ventilation duration (RR = 0.60, 95% CI (- 0.52, 1.72), P = 0.29, I 2  = 97%) and intensive care unit (ICU) stay for both patient groups (RR = 0.47, 95% CI (- 1.02, 1.95), P = 0.54, I 2  = 50%). Due to the marked heterogeneity, a comparison of mechanical ventilation length between the two patient groups was not feasible. However, both studies suggested no significant difference in ventilation duration between patients using metal-coated ETT and those with uncoated ETT., Conclusions: Metal-coated ETT show a lower occurrence of VAP compared to the uncoated ETT. Nevertheless, they do not considerably decrease the length of mechanical ventilation, the duration of ICU admission, nor do they reduce hospital mortality rates., Systematic Review Registration: https://www.crd.york.ac.uk/prospero/ , identifier CRD42024560618., (© 2024.

Objective: This study aimed to evaluate the effect of continuous control cuff pressure (CCCP) versus intermittent control cuff pressure (ICCP) for the prevention of ventilator-associated pneumonia (VAP) in critically ill patients., Methods: Relevant literature was searched in several databases, including PubMed, Embase, Web of Science, ProQuest, the Cochrane Library, Wanfang Database and China National Knowledge Infrastructure between inception and September 2022. Randomized controlled trials were considered eligible if they compared CCCP with ICCP for the prevention of VAP in critically ill patients. This meta-analysis was performed using the RevMan 5.3 and Trial Sequential Analysis 0.9 software packages. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework was used to assess the level of evidence., Results: We identified 14 randomized control trials with a total of 2080 patients. Meta-analysis revealed that CCCP was associated with a significantly lower incidence of VAP compared with ICCP (relative risk [RR] = 0.52; 95% confidence interval [CI]: 0.37-0.74; P  < 0.001), although considerable heterogeneity was observed ( I 2  = 71%). Conducting trial sequential analysis confirmed the finding, and the GRADE level was moderate. Subgroup analysis demonstrated that CCCP combined with subglottic secretion drainage (SSD) had a more significant effect on reducing VAP (RR = 0.39; 95% CI = 0.29-0.52; P  < 0.001). The effect of CCCP on ventilator-associated respiratory infection (VARI) incidence was uncertain (RR = 0.81; 95% CI = 0.53-1.24; P  = 0.34; I 2  = 61%). Additionally, CCCP significantly reduced the duration of mechanical ventilation (MV) (mean difference [MD] = -2.42 days; 95% CI = -4.71-0.12; P  = 0.04; I 2  = 87%). Descriptive analysis showed that CCCP improved the qualified rate of cuff pressure. However, no significant differences were found in the length of intensive care unit (ICU) stay (MD = 2.42 days; 95% CI = -1.84-6.68; P  = 0.27) and ICU mortality (RR = 0.86; 95% CI = 0.74-1.00; P  = 0.05)., Conclusion: Our findings suggest that the combination of CCCP and SSD can reduce the incidence of VAP and the duration of MV and maintain the stability of cuff pressure. A combination of CCCP and SSD applications is suggested for preventing VAP., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

We review the pathophysiology, epidemiology, diagnosis, treatment, and prevention of ventilator-associated pneumonia (VAP) in neonates. VAP has been studied primarily in adult ICU patients, although there has been more focus on pediatric and neonatal VAP (neo-VAP) in the last decade. The definition as well as diagnosis of VAP in neonates remains a challenge to date. The neonatal intensivist needs to be familiar with the current diagnostic tools and prevention strategies available to treat and reduce VAP to reduce neonatal morbidity and the emergence of antibiotic resistance. This review also highlights preventive strategies and old and emerging treatments available., (© 2024. The Author(s).)

Ventilator-associated pneumonia (VAP) is a common healthcare-acquired infection often arising during artificial ventilation using endotracheal intubation (ETT), which offers a platform for bacterial colonization and biofilm development. In particular, the effects of prolonged COVID-19 on the respiratory system. Herein, we developed an antimicrobial coating (FK-MEM@CMCO-CS) capable of visualizing pH changes based on bacterial infection and releasing meropenem (MEM) and FK13-a1 in a controlled manner. Using a simple dip-coating process with controlled loading, chitosan was cross-linked with sodium carboxymethyl cellulose oxidation (CMCO) and coated onto PVC-based ETT to form a hydrogel coating. Subsequently, the coated segments were immersed in an indicator solution containing bromothymol blue (BTB), MEM, and FK13-a1 to fabricate the FK-MEM@CMCO-CS coating. In vitro studies have shown that MEM and FK13-a1 can be released from coatings in a pH-responsive manner. Moreover, anti-biofilm and antibacterial adhesion results showed that FK-MEM@CMCO-CS coating significantly inhibited biofilm formation and prevented their colonization of the coating surface. In the VAP rat model, the coating inhibited bacterial growth, reduced lung inflammation, and had good biocompatibility. The coating can be applied to the entire ETT and has the potential for industrial production., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Introduction: Ventilator-associated pneumonia (VAP) is associated with increased mortality, prolonged mechanical ventilation, and longer intensive care unit stays. The rate of VAP (VAPs per 1000 ventilator days) within a hospital is an important quality metric. Despite adoption of preventative strategies, rates of VAP in injured patients remain high in trauma centers. Here, we report variation in risk-adjusted VAP rates within a statewide quality collaborative., Methods: Using Michigan Trauma Quality Improvement Program data from 35 American College of Surgeons-verified Level I and Level II trauma centers between November 1, 2020 and January 31, 2023, a patient-level Poisson model was created to evaluate the risk-adjusted rate of VAP across institutions given the number of ventilator days, adjusting for injury severity, physiologic parameters, and comorbid conditions. Patient-level model results were summed to create center-level estimates. We performed observed-to-expected adjustments to calculate each center's risk-adjusted VAP days and flagged outliers as hospitals whose confidence intervals lay above or below the overall mean., Results: We identified 538 VAP occurrences among a total of 33,038 ventilator days within the collaborative, with an overall mean of 16.3 VAPs per 1000 ventilator days. We found wide variation in risk-adjusted rates of VAP, ranging from 0 (0-8.9) to 33.0 (14.4-65.1) VAPs per 1000 d. Several hospitals were identified as high or low outliers., Conclusions: There exists significant variation in the rate of VAP among trauma centers. Investigation of practices and factors influencing the differences between low and high outlier institutions may yield information to reduce variation and improve outcomes., (Copyright © 2024 Elsevier Inc.

Objective: To design, develop and validate a new tool, called NEUMOBACT, to evaluate critical care nurses' knowledge and skills in ventilator-associated pneumonia (VAP) and catheter-related bacteraemia (CRB) prevention through simulation scenarios involving central venous catheter (CVC), endotracheal suctioning (ETS) and mechanically ventilated patient care (PC) stations., Background: Simulation-based training is an excellent way for nurses to learn prevention measures in VAP and CRB., Design: Descriptive metric study to develop NEUMOBACT and analyse its content and face validity that followed the COSMIN Study Design checklist for patient-reported outcome measurement instruments., Methods: The first version was developed with the content of training modules in use at the time (NEUMOBACT-1). Delphi rounds were used to assess item relevance with experts in VAP and CRB prevention measures, resulting in NEUMOBACT-2. Experts in simulation methods then assessed feasibility, resulting in NEUMOBACT-3. Finally, a pilot test was conducted among 30 intensive care unit (ICU) nurses to assess the applicability of the evaluation tool in clinical practice., Results: Seven national experts in VAP and CRB prevention and seven national simulation experts participated in the analysis to assess the relevance and feasibility of each item, respectively. After two Delphi rounds with infection experts, four Delphi rounds with simulation experts, and pilot testing with 30 ICU nurses, the NEUMOBACT-FINAL tool consisted of 17, 26 and 21 items, respectively, for CVC, ETS and PC., Conclusion: NEUMOBACT-FINAL is useful and valid for assessing ICU nurses' knowledge and skills in VAP and CRB prevention, acquired through simulation., Relevance for Clinical Practice: Our validated and clinically tested tool could facilitate the transfer of ICU nurses' knowledge and skills learning in VAP and CRB prevention to critically ill patients, decreasing infection rates and, therefore, improving patient safety., Patient or Public Contribution: Experts participated in the Delphi rounds and nurses in the pilot test., (© 2024 The Authors.

Background: Device-associated infections (DAIs) are a significant cause of morbidity following living donor liver transplantation (LDLT). We aimed to assess the impact of bundled care on reducing rates of device-associated infections., Methods: We performed a before-and-after comparative study at a liver transplantation facility over a three-year period, spanning from January 2016 to December 2018. The study included a total of 57 patients who underwent LDLT. We investigated the implementation of a care bundle, which consists of multiple evidence-based procedures that are consistently performed as a unified unit. We divided our study into three phases and implemented a bundled care approach in the second phase. Rates of pneumonia related to ventilators [VAP], bloodstream infections associated with central line [CLABSI], and urinary tract infections associated with catheters [CAUTI] were assessed throughout the study period. Bacterial identification and antibiotic susceptibility testing were performed using the automated Vitek-2 system. The comparison between different phases was assessed using the chi-square test or the Fisher exact test for qualitative values and the Kruskal-Wallis H test for quantitative values with non-normal distribution., Results: In the baseline phase, the VAP rates were 73.5, the CAUTI rates were 47.2, and the CLABSI rates were 7.4 per one thousand device days (PDD). During the bundle care phase, the rates decreased to 33.3, 18.18, and 4.78. In the follow-up phase, the rates further decreased to 35.7%, 16.8%, and 2.7% PDD. The prevalence of Klebsiella pneumonia (37.5%) and Methicillin resistance Staph aureus (37.5%) in VAP were noted. The primary causative agent of CAUTI was Candida albicans, accounting for 33.3% of cases, whereas Coagulase-negative Staph was the predominant organism responsible for CLABSI, with a prevalence of 40%., Conclusion: This study demonstrates the effectiveness of utilizing the care bundle approach to reduce DAI in LDLT, especially in low socioeconomic countries with limited resources. By implementing a comprehensive set of evidence-based interventions, healthcare systems can effectively reduce the burden of DAI, enhance infection prevention strategies and improve patient outcomes in resource-constrained settings., (© 2024.

Background: The objective of this study is to assess the impact of an early-graded pulmonary rehabilitation training program on patients undergoing mechanical ventilation due to brainstem hemorrhage., Methods: Eighty patients receiving mechanical ventilation due to brainstem hemorrhage at our hospital's neurosurgery department between August 2022 and October 2023 were enrolled as participants. A sampling table was generated based on the order of admission, and 80 random sequences were generated using SPSS software. These sequences were then sorted in ascending order, with the first half designated as the control group and the second half as the intervention group, each comprising 40 cases. The control group received standard nursing care for mechanical ventilation in brainstem hemorrhage cases, while the intervention group underwent early-graded pulmonary rehabilitation training in addition to standard care. This intervention was conducted in collaboration with a multidisciplinary respiratory critical care rehabilitation team. The study compared respiratory function indices, ventilator weaning success rates, ventilator-associated pneumonia incidence, mechanical ventilation duration, and patient discharge duration between the 2 groups., Results: The comparison between patients in the observation group and the control group regarding peak expiratory flow and maximum inspiratory pressure on days 1, 3, 5, and 7 revealed statistically significant differences (P < .05). Additionally, there was a statistically significant interaction between the main effect of intervention and the main effect of time (P < .05). The success rate of ventilator withdrawal was notably higher in the observation group (62.5%) compared to the control group (32.5%), with a statistically significant difference (P < .05). Moreover, the incidence rate of ventilator-associated pneumonia was significantly lower in the observation group (2.5%) compared to the control group (17.5%) (P < .05). Furthermore, both the duration of mechanical ventilation and hospitalization were significantly shorter in the observation group compared to the control group (P < .05)., Conclusion: Early-graded pulmonary rehabilitation training demonstrates effectiveness in enhancing respiratory function, augmenting the ventilator withdrawal success rate, and reducing both the duration of mechanical ventilation and hospitalization in mechanically ventilated patients with brainstem hemorrhage. These findings suggest the potential value of promoting the application of this intervention in clinical practice., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Objectives: To evaluated the home healthcare efficacy in managing tracheostomy patients at King Abdulaziz Medical City under the Ministry of National Guard Health Affairs. Home healthcare is care provided to patients in the convenience of their homes to ensure high-quality care based on healthcare providers' supervision., Methods: This retrospective cohort study utilizing a non-probability consecutive sampling technique, including all available tracheal patients with no exclusion criteria, was carried out in Riyadh, Saudi Arabia, between January 2019 and June 2022. The collected data included patient demographic variables and respiratory settings (ventilation type, daily ventilation need, tracheostomy duration, and ventilator settings). The outcomes included mortality rate and therapeutic outcomes of tracheal management., Results: Of the 183 patients in the study, the most common type of respiratory-related infection was pneumonia (53%). Unlike respiratory-related causes, The mortality rate of patients admitted to the intensive care unit that was unrelated to respiratory causes was statistically significant (57%) ( p =0.003). The mortality rate of patients who used aerosol tracheal collars (34%) was markedly higher than mechanically ventilated patients (57%) ( p =0.004). The mortality rate following discharge from HHC was 40%, and was higher among patients aged >70 years (47%) ( p =0.04)., Conclusion: Pneumonia was associated with the majority of ventilator-related infections and resulted in hospital readmissions. Ensuring proper practices and caregiver education is crucial to decrease the incidence of ventilator-related infections., (Copyright: © Saudi Medical Journal.)

The COVID-19 pandemic has had an unprecedented impact on population health and hospital operations. Over 7 million patients have been hospitalized for COVID-19 thus far in the United States alone. Mortality rates for hospitalized patients during the first wave of the pandemic were > 30%, but as we enter the fifth year of the pandemic hospitalizations have fallen and mortality rates for hospitalized patients with COVID-19 have plummeted to 5% or less. These gains reflect lessons learned about how to optimize respiratory support for different kinds of patients, targeted use of therapeutics for patients with different manifestations of COVID-19 including immunosuppressants and antivirals as appropriate, and high levels of population immunity acquired through vaccines and natural infections. At the same time, the pandemic has helped highlight some longstanding sources of harm for hospitalized patients including hospital-acquired pneumonia, ventilator-associated events (VAEs), and hospital-acquired respiratory viral infections. We are, thankfully, on the leeside of the pandemic at present; but the large increases in ventilator-associated pneumonia (VAP), VAEs, bacterial superinfections, and nosocomial respiratory viral infections associated with the pandemic beg the question of how best to prevent these complications moving forward. This paper reviews the burden of hospitalization for COVID-19, the intersection between COVID-19 and both VAP and VAEs, the frequency and impact of hospital-acquired respiratory viral infections, new recommendations on how best to prevent VAP and VAEs, and current insights into effective strategies to prevent nosocomial spread of respiratory viruses., Competing Interests: Dr Klompas discloses relationships with Centers for Disease Control and Prevention, AHRQ, and UpToDate., (Copyright © 2024 by Daedalus Enterprises.)

Background: The recommendation for Chlorhexidine (CHX) as a traditional oral care solution is decreasing, and herbal oral care products are being considered as a potential alternative. This network meta-analysis aims to determine if herbal oral care products for oral care in mechanically ventilated patients are superior to CHX and provide direction for future research by comparing the effectiveness of herbal oral care products currently available., Materials and Methods: We searched for English-language published and grey literature sources of randomized clinical trials involving herbal oral care solutions in intensive care unit (ICU) oral care (until September 2023). The primary outcome was the incidence of ventilator-associated pneumonia (VAP); the secondary outcome was the oral microbiota quantity. Data were pooled by pairwise meta-analysis and Bayesian network meta-analysis. The risk of bias was assessed using the Cochrane risk of bias tool, and the certainty of evidence was evaluated using the GRADE framework., Results: Our network meta-analysis included 29 studies, and the results showed that Chinese herb (OR: 0.39, 95% CI: 0.2-0.75) and Miswak (OR: 0.27, 95% CI: 0.07-0.91) were more effective in reducing VAP incidence than CHX. In terms of reducing bacterial counts, Chinese herb (OR: 0.3, 95% CI: 0.19-0.48) was superior to CHX, and all herbal oral care products, including Persica® (alcoholic extract of S. persica, Achillea millefolium, and Mentha spicata), Matrica® (Chamomile extract), and Listerine® (main components include Menthol, Thymol, and Eucalyptol), were better than saline in all aspects but without significant differences., Conclusion: Based on our network meta-analysis, we have observed that Chinese herbal medicine and Miswak are superior to CHX in reducing the incidence of VAP. However, the safety and feasibility of traditional Chinese herbal medicine require further high-quality research for validation. Simultaneously, Matrica® demonstrates a significant reduction in microbial counts but does not exhibit a significant advantage in lowering the incidence of VAP. This observation aligns with the results of clinical double-blind trials. Therefore, we identify Miswak and Matrica® as promising herbal oral care products with the potential to replace CHX. It is essential to emphasize that our study provides guidance for future research rather than conclusive determinations., Registration: PROSPERO no.

The literature regarding the role of probiotics in critically ill patients who have undergone mechanical ventilation (MV) is unclear; therefore, this umbrella systematic review and meta-analysis was carried out to clarify the effects of probiotics on the clinical outcomes of mechanically ventilated patients. The Scopus, PubMed/Medline, ISI Web of Science, and Google Scholar online databases were searched up to February 2023. All meta-analyses evaluating the impact of probiotics in patients under MV were considered eligible. The assessment of multiple systematic reviews (AMSTAR) questionnaire was used to evaluate the quality of the studies. Data were pooled using the random-effects approach. Thirty meta-analyses and nine clinical outcomes were re-analyzed. Probiotics significantly decreased ventilator-associated pneumonia (VAP) incidence, nosocomial infections, intensive care unit (ICU) length of stay, hospital length of stay, ICU mortality, hospital mortality, MV duration, duration of antibiotic use, and diarrhea. The obtained results of the current umbrella meta-analysis indicate that probiotic administration could be considered an adjunct therapy for critically ill patients; however, no specific probiotic treatment regimen can be recommended due to the diverse probiotics used in the included meta-analyses. The following microorganisms were used at various doses and combinations throughout the studies: Lacticaseibacillus casei , Lactiplantibacillus plantarum , L. acidophilus , L. delbrueckii , L. bulgaricus , Bifidobacterium longum , B. breve , B. salivarius , Pediococcus pentosaceus , Lactococcus raffinolactis , B. infantis , B. bifidum , Streptococcus thermophilus , Ligilactobacillus salivarius , L. lactis , B. lactis , Saccharomyces boulardii , L. rhamnosus GG, L. johnsonii , L. casei , S. faecalis , Clostridium butyricum , Bacillus mesentericus , L. sporogenes , S. boulardii , L. paracasei , B. subtilis , and Enterococcus faecium .

Background: Ventilator-associated events (VAE) is a tier implemented for surveillance by the CDC in the USA. Implementation usefulness for clinical decisions is unknown., Methods: We conducted a secondary analysis from a prospective, multicentre, international study, to assess the impact on outcomes of using tiers with shorter follow-up (VAE24), lower oxygenation requirements (light-VAE) or both (light VAE24)., Results: A cohort of 261 adults with 2706 ventilator-days were included. The median (IQR) duration of mechanical ventilation (MV) was 9 days (5-21), and the median (IQR) length of stay in the intensive care unit (ICU) was 14 days (8-26). A VAE tier was associated with a trend to increase from 32% to 44% in the ICU mortality rates. VAE Incidence was 24 per 1,000 ventilator-days, being increased when reduced the oxygenation settings requirement (35 per 1,000 ventilator-days), follow-up (41 per 1,000 ventilator-days) or both (55 per 1,000 ventilator-days). A VAE tier was associated with 13 extra (21 vs. 8) days of ventilation, 11 (23 vs. 12) ICU days and 7 (31 vs. 14) hospitalization days, outperforming the modified tiers' performance., Conclusions: The modification of ventilator settings (consistent with ventilator-associated events) was associated with worse outcomes among adults with prolonged mechanical ventilation. Monitoring ventilator-associated events at the bedside represents a new tool for quality improvement., (Copyright © 2024 Société française d'anesthésie et de réanimation (Sfar).

In recent years, it has become increasingly evident that surveillance metrics for invasive device-associated infections (ie, central-line-associated bloodstream infections, ventilator-associated pneumonias, and catheter-associated urinary tract infections) do not capture all harms; they capture only a subset of healthcare-associated infections (HAIs). Although prevention of device-associated infections remains critical, we need to address the full spectrum of potential harms from device use and non-device-associated infections. These include complications associated with additional devices, such as peripheral venous and arterial catheters, non-device-associated infections such as nonventilator hospital-acquired pneumonia, and noninfectious device complications such as trauma, thrombosis, and acute lung injury. As authors of the device-associated infection sections in the SHEA/IDSA/APIC Compendium of Strategies to Prevent Healthcare-Associated Infections in Acute Care Hospitals , we highlight catheter-associated urinary tract infection as an example of the strengths and limitations of the current emphasis on device-associated infection surveillance, suggest performance metrics that present a more comprehensive picture of patient harm, and provide a high-level overview of similar issues with other infection surveillance measures.

Objectives: Ventilator-associated pneumonia (VAP) increases the length of hospitalization and mortality rate. This study aimed to determine the effect of propolis mouthwash on the incidence of VAP in intensive care unit (ICU) patients., Materials and Methods: Triple-blind, comparative randomized, controlled clinical trial was conducted over one year, with 110 ICU patients at Imam-Hossein and Bahar hospitals (Shahroud) and Kowsar Hospital (Semnan) in Iran. The intervention group used 15 cc of 0.06% propolis mouthwash solution twice daily at 8 AM and 4 PM for seven days. The control group used 15 cc of 0.2% chlorhexidine mouthwash at the same times and duration. Data were collected using a demographic questionnaire, APACHE II, Beck Oral Assessment Scale, and Modified Clinical Pulmonary Infection Score (MCPIS)., Results: There was no significant difference in demographic information, disease severity, and oral health between the two groups before and after intervention (P > 0.05). The incidence of VAP in the intervention group compared to the control group was 10.9% vs. 30.9% on the third day (P = 0.0166, 95% CI: 0.53-0.83 and RR = 0.35), 23.6% vs. 43.6% on the fifth day (P = 0.0325 and 95% CI: 0.31-0.95 and RR = 0.54), and 25.5% vs. 47.3% on the seventh day (P = 0.0224, 95% CI: 0.32-0.92, and RR = 0.54). The Mann-Whitney indicated the incidence of VAP was significantly lower in the intervention group on the third, fifth, and seventh days., Conclusion: Propolis mouthwash can be considered as an alternative to chlorhexidine mouthwash for ICU patients., Clinical Relevance: Propolis mouthwash serves as a simple, economical intervention to potentially reduce incidence of VAP., Trial Registration: (IRCT20110427006318N12, date 02.04.2019)., (© 2024.

Background: Extended illness-death models (a specific class of multistate models) are a useful tool to analyse situations like hospital-acquired infections, ventilation-associated pneumonia, and transfers between hospitals. The main components of these models are hazard rates and transition probabilities. Calculation of different measures and their interpretation can be challenging due to their complexity., Methods: By assuming time-constant hazards, the complexity of these models becomes manageable and closed mathematical forms for transition probabilities can be derived. Using these forms, we created a tool in R to visualize transition probabilities via stacked probability plots., Results: In this article, we present this tool and give some insights into its theoretical background. Using published examples, we give guidelines on how this tool can be used. Our goal is to provide an instrument that helps obtain a deeper understanding of a complex multistate setting., Conclusion: While multistate models (in particular extended illness-death models), can be highly complex, this tool can be used in studies to both understand assumptions, which have been made during planning and as a first step in analysing complex data structures.

Background: Patients with acute brain injury are at high risk of ventilator-associated pneumonia (VAP). The benefit of short-term antibiotic prophylaxis remains debated. We aimed to establish the effect of an early, single dose of the antibiotic ceftriaxone on the incidence of early VAP in patients with severe brain injury who required mechanical ventilation., Methods: PROPHY-VAP was a multicentre, randomised, double-blind, placebo-controlled, assessor-masked, superiority trial conducted in nine intensive care units in eight French university hospitals. We randomly assigned comatose (Glasgow Coma Scale score [GCS] ≤12) adult patients (age ≥18 years) who required mechanical ventilation for at least 48 h after acute brain injury to receive intravenous ceftriaxone 2 g or placebo once within the 12 h following tracheal intubation. Participants did not receive selective oropharyngeal and digestive tract decontamination. The primary outcome was the proportion of patients developing early VAP from the 2nd to the 7th day of mechanical ventilation, confirmed by masked assessors. The analysis was reported in the modified intention-to-treat population, which comprised all randomly assigned patients except those who withdrew or did not give consent to continue and those who did not receive the allocated treatment because they met a criterion for non-eligibility. The trial is registered with ClinicalTrials.gov, NCT02265406., Findings: From Oct 14, 2015, to May 27, 2020, 345 patients were randomly assigned (1:1) to receive ceftriaxone (n=171) or placebo (n=174); 330 received the allocated intervention and 319 were included in the analysis (162 in the ceftriaxone group and 157 in the placebo group). 166 (52%) participants in the analysis were men and 153 (48%) were women. 15 patients did not receive the allocated intervention after randomisation and 11 withdrew their consent. Adjudication confirmed 93 cases of VAP, including 74 early infections. The incidence of early VAP was lower in the ceftriaxone group than in the placebo group (23 [14%] vs 51 [32%]; hazard ratio 0·60 [95% CI 0·38-0·95], p=0·030), with no microbiological impact and no adverse effects attributable to ceftriaxone., Interpretation: In patients with acute brain injury, a single ceftriaxone dose decreased the risk of early VAP. On the basis of our findings, we recommend that an early, single dose of ceftriaxone be included in all bundles for the prevention of VAP in patients with brain injury who require mechanical ventilation., Funding: French Ministry of Social Affairs and Health., (Copyright © 2024 Elsevier Ltd.

Introduction: Ventilator associated pneumonia (VAP) leads to an increase in morbidity, mortality, and healthcare costs. In addition to increased evidence from the latest European and American guidelines (published in 2017 and 2022, respectively), in the last two years, several important clinical experiences have added new prevention tools to be included to improve the management of VAP., Areas Covered: This paper is a narrative review of new evidence on VAP prevention. We divided VAP prevention measures into pharmacological, non-pharmacological, and ventilator care bundles., Expert Opinion: Most of the effective strategies that have been shown to decrease the incidence of complications are easy to implement and inexpensive. The implementation of care bundles, accompanied by educational measures and a multidisciplinary team should be part of optimal management. In addition to ventilator care bundles for the prevention of VAP, it could possibly be beneficial to use ventilator care bundles for the prevention of noninfectious ventilator associated events.

The endotracheal tube (ETT) affords support for intubated patients, but the increasing incidence of ventilator-associated pneumonia (VAP) is jeopardizing its application. ETT surfaces promote (poly)microbial colonization and biofilm formation, with a heavy burden for VAP. Devising safe, broad-spectrum antimicrobial materials to tackle the ETT bioburden is needful. Herein, we immobilized ciprofloxacin (CIP) and/or chlorhexidine (CHX), through polydopamine (pDA)-based functionalization, onto poly(vinyl chloride) (PVC) surfaces. These surfaces were characterized regarding physicochemical properties and challenged with single and polymicrobial cultures of VAP-relevant bacteria ( Pseudomonas aeruginosa , Acinetobacter baumannii , Klebsiella pneumoniae , Staphylococcus aureus , Staphylococcus epidermidis ) and fungi ( Candida albicans ). The coatings imparted PVC surfaces with a homogeneous morphology, varied wettability, and low roughness. The antimicrobial immobilization via pDA chemistry was still evidenced by infrared spectroscopy. Coated surfaces exhibited sustained CIP/CHX release, retaining prolonged (10 days) activity. CIP/CHX-coated surfaces evidencing no A549 lung cell toxicity displayed better antibiofilm outcomes than CIP or CHX coatings, preventing bacterial attachment by 4.1-7.2 Log 10 CFU/mL and modestly distressing C. albicans . Their antibiofilm effectiveness was endured toward polymicrobial consortia, substantially inhibiting the adhesion of the bacterial populations (up to 8 Log 10 CFU/mL) within the consortia in dual- and even in P. aeruginosa / S. aureus / C. albicans triple-species biofilms while affecting fungal adhesion by 2.7 Log 10 CFU/mL (dual consortia) and 1 Log 10 CFU/mL (triple consortia). The potential of the dual-drug coating strategy in preventing triple-species adhesion and impairing bacterial viability was still strengthened by live/dead microscopy. The pDA-assisted CIP/CHX co-immobilization holds a safe and robust broad-spectrum antimicrobial coating strategy for PVC-ETTs, with the promise laying in reducing VAP incidence.

Introduction: Non-ventilator-associated hospital-acquired pneumonia is a preventable health care-associated infection accounting for 1 in 14 hospital deaths. Clinical factors influencing this condition include oral health and bacteria and oral care. This case report addresses diagnostics and clinical variables related to non-ventilator-associated hospital-acquired pneumonia and emphasizes the importance of prevention., Clinical Findings: A 90-year-old woman was admitted to the hospital with shortness of breath and generalized weakness from new-onset atrial fibrillation and suspected heart failure exacerbation. During the hospitalization, her oral health status declined and oral bacterial colonization shifted, with Neisseria becoming the most common oral bacterial genus around the time of development of probable non-ventilator-associated hospital-acquired pneumonia., Diagnosis: The patient had new respiratory symptoms and a chest radiograph positive for pneumonia on day 4 and was subsequently diagnosed with probable non-ventilator-associated hospital-acquired pneumonia., Interventions: Intravenous antibiotic treatment was initiated. Oral care was completed on only 2 of 7 days. The patient received limited ambulation assistance and encouragement from staff and family members. No dysphagia screening was documented., Outcomes: On day 6, the patient was discharged with oral antibiotics to her independent living facility with home health care., Conclusions: Consistent oral care, early and frequent physical activity, and measures aimed to reduce aspiration risk are key interventions for all hospitalized patients to prevent non-ventilator-associated hospital-acquired pneumonia. Further research is warranted to assess shifts in oral bacteria and general oral health during hospitalization, which could provide clinically meaningful data on risk for non-ventilator-associated hospital-acquired pneumonia., (©2024 American Association of Critical-Care Nurses.)

Background: Ventilator associated pneumonia (VAP) occurring in the intensive care unit (ICU) are common, costly, and potentially lethal., Methods: We implemented a multidimensional approach and an 8-component bundle in 374 ICUs across 35 low and middle-income countries (LMICs) from Latin-America, Asia, Eastern-Europe, and the Middle-East, to reduce VAP rates in ICUs. The VAP rate per 1000 mechanical ventilator (MV)-days was measured at baseline and during intervention at the 2nd month, 3rd month, 4-15 month, 16-27 month, and 28-39 month periods., Results: 174,987 patients, during 1,201,592 patient-days, used 463,592 MV-days. VAP per 1000 MV-days rates decreased from 28.46 at baseline to 17.58 at the 2nd month (RR = 0.61; 95% CI = 0.58-0.65; P < 0.001); 13.97 at the 3rd month (RR = 0.49; 95% CI = 0.46-0.52; P < 0.001); 14.44 at the 4-15 month (RR = 0.51; 95% CI = 0.48-0.53; P < 0.001); 11.40 at the 16-27 month (RR = 0.41; 95% CI = 0.38-0.42; P < 0.001), and to 9.68 at the 28-39 month (RR = 0.34; 95% CI = 0.32-0.36; P < 0.001). The multilevel Poisson regression model showed a continuous significant decrease in incidence rate ratios, reaching 0.39 (p < 0.0001) during the 28th to 39th months after implementation of the intervention., Conclusions: This intervention resulted in a significant VAP rate reduction by 66% that was maintained throughout the 39-month period., Competing Interests: Declaration of Competing Interest All authors declare that don't have any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work.

Objective: This study aimed to compare the ventilator-free days (VFDs) at day 28 and the short-term outcomes in neonates with and without ventilator-associated pneumonia (VAP and non-VAP groups)., Study Design: We performed a cohort study in a Thai neonatal intensive care unit between 2014 and 2020 to identify the VFDs in VAP and non-VAP neonates. Univariate and multivariate analyses were performed., Results: The incidences of VAP rates were 5.76% (67/1,163 neonates) and 10.86 per 1,000 (92/8,469) ventilator days. The medians (interquartile ranges [IQRs]) of gestational age and birth weight in the VAP versus non-VAP groups were 31 (27-35) versus 34 (30-38) weeks, and 1,495 (813-2,593) versus 2,220 (1,405-2,940) g ( p  < 0.001, both), respectively. The medians (IQRs) of VFDs at 28 days in the VAP and non-VAP groups were 5 (0-16) and 24 (20-26) days ( p  < 0.001). From the univariate analysis, the lower VFDs, longer ventilator days, and higher rates of moderate-to-severe bronchopulmonary dysplasia (BPD), postnatal steroids for BPD, length of stay, and daily hospital cost in the VAP group were significantly higher than in the non-VAP group. From the multivariate analysis, the VAP group had significantly lower VFDs (regression coefficient = -10.99, standard error = 1.11, p  < 0.001) and higher BPD (adjusted risk ratio = 18.70; 95% confidence interval = 9.17-39.5, p  < 0.001) than the non-VAP group., Conclusion: Neonatal VAP lead to lower VFDs and a higher frequency of BPD. A multimodal strategy with a VAP prevention bundle care should be used in indicated cases to reduce the occurrence of neonatal VAP., Key Points: · The VFDs of the neonatal VAP was lower than reported in adult study.. · There are limited data on VFDs in VAP during the neonatal period.. · Neonatal VAP reduces VFDs and increases BPD rates compared with non-VAP infants.., Competing Interests: None declared., (Thieme.

Oral care for critically ill patients helps provide comfort and prevent ventilator-associated pneumonia. However, a standardized protocol for oral care in intensive care units is currently unavailable. Thus, this study aimed to determine the overall oral care practices, including those for intubated patients, in Japanese intensive care units. We also discuss the differences in oral care methods between Japanese ICUs and ICUs in other countries. This study included all Japanese intensive care units meeting the authorities' standard set criteria, with a minimum of 0.5 nurses per patient at all times and admission of adult patients requiring mechanical ventilation. An online survey was used to collect data. Survey responses were obtained from one representative nurse per intensive care unit. Frequency analysis was performed, and the percentage of each response was calculated. A total of 609 hospitals and 717 intensive care units nationwide participated; among these, responses were collected from 247 intensive care units (34.4%). Of these, 215 (87.0%) and 32 (13.0%) reported standardized and non-standardized oral care, respectively. Subsequently, the data from 215 intensive care units that provided standardized oral care were analyzed in detail. The most common frequency of practicing oral care was three times a day (68.8%). Moreover, many intensive care units provided care at unequal intervals (79.5%), mainly in the morning, daytime, and evening. Regarding oral care methods, 96 (44.7%) respondents used only a toothbrush, while 116 (54.0%) used both a toothbrush and a non-brushing method. The findings of our study reveal current oral care practices in ICUs in Japan. In particular, most ICUs provide oral care three times a day at unequal intervals, and almost all use toothbrushes as a common tool for oral care. The results suggest that some oral care practices in Japanese ICUs differ from those in ICUs in other countries., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Kuribara et al.

Many meta-analyses have assessed the efficacy of preventive interventions against ventilator-associated pneumonia (VAP) in critically ill patients. However, there has been no comprehensive analysis of the strength and quality of evidence to date. Systematic reviews of randomized and quasi-randomized controlled trials, which evaluated the effect of preventive strategies on the incidence of VAP in critically ill patients receiving mechanical ventilation for at least 48 h, were included in this article. We identified a total of 34 interventions derived from 31 studies. Among these interventions, 19 resulted in a significantly reduced incidence of VAP. Among numerous strategies, only selective decontamination of the digestive tract (SDD) was supported by highly suggestive (Class II) evidence (risk ratio (RR)=0.439, 95% CI: 0.362-0.532). Based on data from the sensitivity analysis, the evidence for the efficacy of non-invasive ventilation in weaning from mechanical ventilation (NIV) was upgraded from weak (Class IV) to highly suggestive (Class II) (RR=0.32, 95% CI: 0.22-0.46). All preventive interventions were not supported by robust evidence for reducing mortality. Early mobilization exhibited suggestive (Class III) evidence in shortening both intensive length of stay (LOS) in the intensive care unit (ICU) (mean difference (MD)=-0.85, 95% CI: -1.21 to -0.49) and duration of mechanical ventilation (MD=-1.02, 95% CI: -1.41 to -0.63). In conclusion, SDD and NIV are supported by robust evidence for prevention against VAP, while early mobilization has been shown to significantly shorten the LOS in the ICU and the duration of mechanical ventilation. These three strategies are recommendable for inclusion in the ventilator bundle to lower the risk of VAP and improve the prognosis of critically ill patients., (Copyright © 2024 The Healthcare Infection Society.

Ventilator-associated pneumonia (VAP) remains a significant clinical entity with reported incidence rates of 7% to 15%. Given the considerable adverse consequences associated with this infection, VAP prevention became a core measure required in most US hospitals. Many institutions took pride in implementing effective VAP prevention bundles that combined at least head of bed elevation, hand hygiene, chlorhexidine oral care, and subglottic drainage. Spontaneous breathing and awakening trials have also consistently been shown to shorten the duration of mechanical ventilation and secondarily reduce the occurrence of VAP., Competing Interests: Disclosures Dr M.H.
