- Abstract
OBJECTIVES: To understand the unmet needs of caregivers of ICU survivors, how they accessed support post ICU, and the key components of beneficial ICU recovery support systems as identified from a caregiver perspective. DESIGN: International, qualitative study. SUBJECTS: We conducted 20 semistructured interviews with a diverse group of caregivers in the United States, the United Kingdom, and Australia, 11 of whom had interacted with an ICU recovery program. SETTING: Seven hospitals in the United States, United Kingdom, and Australia. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Content analysis was used to explore prevalent themes related to unmet needs, as well as perceived strategies to improve ICU outcomes. Post-ICU care was perceived to be generally inadequate. Desired caregiver support fell into two main categories: practical support and emotional support. Successful care delivery initiatives included structured programs, such as post discharge telephone calls, home health programs, post-ICU clinics, and peer support groups, and standing information resources, such as written educational materials and online resources. CONCLUSIONS: This qualitative, multicenter, international study of caregivers of critical illness survivors identified consistently unmet needs, means by which caregivers accessed support post ICU, and several care mechanisms identified by caregivers as supporting optimal ICU recovery.

- Abstract
Background: Persistent critical illness (PerCI) is defined as an intensive care unit (ICU) admission lasting ≥ 10 days. The in-hospital complications associated with its development are poorly understood. Aims: To test whether PerCI is associated with a greater prevalence, rate and specific types of in-hospital complications. Methods: Single-centre, retrospective, observational case-control study. Results: We studied 1200 patients admitted to a tertiary ICU from 2010 to 2015. Median ICU length of stay was 16 days (interquartile range [IQR], 12-23) for PerCI patients v 2.3 days (IQR, 1.1-3.7) for controls, and median hospital length of stay was 41 days (IQR, 22-75) v 8 days (IQR, 4-17) respectively. A greater proportion of PerCI patients received acute renal replacement therapy (37% v 6.8%) or underwent reintubation (17% v 1%) and/or tracheostomy (36% v 0.6%); P < 0.0001. Despite these complications, PerCI patients had similar hospital mortality (29% v 27%; P = 0.53). PerCI patients experienced a greater absolute number of complications (12.1 v 4.0 complications per patient; P < 0.0001) but had fewer exposure-adjusted complications (202 v 272 complications per 1000 hospital bed-days; P < 0.001) and a particularly high overall prevalence of specific complications. Conclusions: PerCI patients experience a higher prevalence, but not a higher rate, of exposure-adjusted complications. Some of these complications appear amenable to prevention, helping to define intervention targets in patients at risk of PerCI. Funding: Austin Hospital Intensive Care Trust Fund.

- Abstract
BACKGROUND: Multiple major health organisations recommend the use of extracorporeal membrane oxygenation (ECMO) support for COVID-19-related acute hypoxaemic respiratory failure. However, initial reports of ECMO use in patients with COVID-19 described very high mortality and there have been no large, international cohort studies of ECMO for COVID-19 reported to date. METHODS: We used data from the Extracorporeal Life Support Organization (ELSO) Registry to characterise the epidemiology, hospital course, and outcomes of patients aged 16 years or older with confirmed COVID-19 who had ECMO support initiated between Jan 16 and May 1, 2020, at 213 hospitals in 36 countries. The primary outcome was in-hospital death in a time-to-event analysis assessed at 90 days after ECMO initiation. We applied a multivariable Cox model to examine whether patient and hospital factors were associated with in-hospital mortality. FINDINGS: Data for 1035 patients with COVID-19 who received ECMO support were included in this study. Of these, 67 (6%) remained hospitalised, 311 (30%) were discharged home or to an acute rehabilitation centre, 101 (10%) were discharged to a long-term acute care centre or unspecified location, 176 (17%) were discharged to another hospital, and 380 (37%) died. The estimated cumulative incidence of in-hospital mortality 90 days after the initiation of ECMO was 37·4% (95% CI 34·4-40·4). Mortality was 39% (380 of 968) in patients with a final disposition of death or hospital discharge. The use of ECMO for circulatory support was independently associated with higher in-hospital mortality (hazard ratio 1·89, 95% CI 1·20-2·97). In the subset of patients with COVID-19 receiving respiratory (venovenous) ECMO and characterised as having acute respiratory distress syndrome, the estimated cumulative incidence of in-hospital mortality 90 days after the initiation of ECMO was 38·0% (95% CI 34·6-41·5). INTERPRETATION: In patients with COVID-19 who received ECMO, both estimated

- Abstract
UNLABELLED: To understand from the perspective of patients who did, and did not attend ICU recovery programs, what were the most important components of successful programs and how should they be organized. DESIGN: International, qualitative study. SETTING: Fourteen hospitals in the United States, United Kingdom, and Australia. PATIENTS: We conducted 66 semi-structured interviews with a diverse group of patients, 52 of whom had used an ICU recovery program and 14 whom had not. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Using content analysis, prevalent themes were documented to understand what improved their outcomes. Contrasting quotes from patients who had not received certain aspects of care were used to identify perceived differential effectiveness. Successful ICU recovery programs had five key components: 1) Continuity of care; 2) Improving symptom status; 3) Normalization and expectation management; 4) Internal and external validation of progress; and 5) Reducing feelings of guilt and helplessness. The delivery of care which achieved these goals was facilitated by early involvement (even before hospital discharge), direct involvement of ICU staff, and a focus on integration across traditional disease, symptom, and social welfare needs. CONCLUSIONS: In this multicenter study, conducted across three continents, patients identified specific and reproducible modes of benefit derived from ICU recovery programs, which could be the target of future intervention refinement.

- Abstract
Rationale: The long-term effects of delivering approximately 100% of recommended calorie intake via the enteral route during critical illness compared with a lesser amount of calories are unknown.Objectives: Our hypotheses were that achieving approximately 100% of recommended calorie intake during critical illness would increase quality-of-life scores, return to work, and key life activities and reduce death and disability 6 months later.Methods: We conducted a multicenter, blinded, parallel group, randomized clinical trial, with 3,957 mechanically ventilated critically ill adults allocated to energy-dense (1.5 kcal/ml) or routine (1.0 kcal/ml) enteral nutrition.Measurements and Main Results: Participants assigned energy-dense nutrition received more calories (percent recommended energy intake, mean [SD]; energy-dense: 103% [28] vs. usual: 69% [18]). Mortality at Day 180 was similar (560/1,895 [29.6%] vs. 539/1,920 [28.1%]; relative risk 1.05 [95% confidence interval, 0.95-1.16]). At a median (interquartile range) of 185 (182-193) days after randomization, 2,492 survivors were surveyed and reported similar quality of life (EuroQol five dimensions five-level quality-of-life questionnaire visual analog scale, median [interquartile range]: 75 [60-85]; group difference: 0 [95% confidence interval, 0-0]). Similar numbers of participants returned to work with no difference in hours worked or effectiveness at work (n = 818). There was no observed difference in disability (n = 1,208) or participation in key life activities (n = 705).Conclusions: The delivery of approximately 100% compared with 70% of recommended calorie intake during critical illness does not improve quality of life or functional outcomes or increase the number of survivors 6 months later.

- Abstract
We aimed to understand the prevalence, timing of onset, resource use, and long-term outcomes of patients who developed persistent critical illness in a national dataset. Design: Retrospective cohort. Using a physiologic risk adjustment model from ICU admission, we examined the relative ability of acute (related to reason for ICU presentation) and antecedent (demographics, comorbidities) characteristics to discriminate hospital mortality models. Persistent critical illness was defined as the point during an ICU stay when, at the population-level, patients' acute diagnoses and physiologic disturbance are no longer more accurate at discriminating who survives than are baseline demographics and comorbidity. We examined the change across ICU stay in the relative discrimination of those characteristics, and short-term (in-hospital and 30 d after admission) and medium-term (90 d after admission) survival. Finally, we analyzed the changes in the population definition of persistent critical illness over time. Setting: Patients admitted as level 3 to Scottish ICUs between 2005 and 2014. Patients: Seventy-two-thousand two-hundred fifty-three adult level 3 ICU admissions in 23 ICUs across Scotland. Interventions: None. Measurements and Main Results: The onset of persistent critical illness, occurs at an average of 5.0 days (95% CI, 3.9-6.4 d) across this dataset. The crossing point increased across the decade, by an average of 0.36 days (95% CI, 0.22-0.50 d) per year. In this dataset, 24,425 (33.8%) remained in the ICU long enough to meet this greater than 5-day definition of persistent critical illness. The care of such patients involved 72.3% ICU days used by any level 3 patient; 46.5% of all Scottish ICU bed-days were after day 5. Although rates of 30 days after admission survival rose dramatically during the decade under study, these rates were similar for those with shorter or longer ICU stays, as were the rates of 90-day survival among those who survived at least 30 days.

- Abstract
BACKGROUND: Physical activity after intensive care unit (ICU) discharge is challenging to measure but could inform research and practice. A patient's smartphone may provide a novel method to quantify physical activity. OBJECTIVES: We aimed to evaluate the feasibility and accuracy of using smartphone step counts among survivors of critical illness. METHODS: We performed a prospective observational cohort study in 50 patients who had an ICU length of stay>48 h, owned a smartphone, were ambulatory before admission, and were likely to attend follow-up at 3 and 6 months after discharge. At follow-up, daily step counts were extracted from participants' smartphones and two FitBit pedometers, and exercise capacity (6-min walk test) and quality of life (European Quality of Life-5 Dimensions) were measured. RESULTS: Thirty-nine (78%) patients returned at 3 months and 33 (66%) at 6 months, the median [interquartile range] smartphone step counts being 3372 [1688-5899] and 2716 [1717-5994], respectively. There was a strong linear relationship, with smartphone approximating 0.71 (0.58, 0.84) of FitBit step counts, P < 0.0001, R-squared = 0.87. There were weak relationships between step counts and the 6-min walk test distance. CONCLUSION: Although smartphone ownership and data acquisition limit the viability of using extracted smartphone steps at this time, mean daily step counts recorded using a smartphone may act as a surrogate for a dedicated pedometer; however, the relationship between step counts and other measures of physical recovery remains unclear.

- Abstract
PURPOSE: Patients with persistent critical illness may account for up to half of all intensive care unit (ICU) bed-days. It is unknown if there is hospital variation in the development of persistent critical illness and if hospital performance affects the incidence of persistent critical illness. METHODS: This is a retrospective analysis of Veterans admitted to the Veterans Administration (VA) ICUs from 2015 to 2017. Hospital performance was defined by the risk- and reliability-adjusted 30-day mortality. Persistent critical illness was defined as an ICU length of stay of at least 11 days. We used 2-level multilevel logistic regression models to assess variation in risk- and reliability-adjusted probabilities in the development of persistent critical illness. RESULTS: In the analysis of 100 hospitals which encompassed 153,512 hospitalizations, 4.9% (N = 7640/153,512) developed persistent critical illness. There was variation in the development of persistent critical illness despite controlling for patient characteristics (intraclass correlation: 0.067, 95% CI 0.049-0.091). Hospitals with higher risk- and reliability-adjusted 30-day mortality had higher probabilities of developing persistent critical illness (predicted probability: 0.057, 95% CI 0.051-0.063, p < 0.01) compared to those with lower risk- and reliability-adjusted 30-day mortality (predicted probability: 0.046, 95% CI 0.041-0.051, p < 0.01). The median odds ratio was 1.4 (95% CI 1.33-1.49) implying that, for two patients with the same physiology on admission at two different VA hospitals, the patient admitted to the hospital with higher adjusted mortality would have 40% greater odds of developing persistent critical illness. CONCLUSION: Hospitals with higher risk- and reliability-adjusted 30-day mortality have a higher probability of developing persistent critical illness. Understanding the drivers of this variation may identify modifiable factors contributing to the development of persistent critical ill

- Abstract
OBJECTIVE: To identify the key mechanisms that clinicians perceive improve care in the intensive care unit (ICU), as a result of their involvement in post-ICU programs. METHODS: Qualitative inquiry via focus groups and interviews with members of the Society of Critical Care Medicine's THRIVE collaborative sites (follow-up clinics and peer support). Framework analysis was used to synthesize and interpret the data. RESULTS: Five key mechanisms were identified as drivers of improvement back into the ICU: (1) identifying otherwise unseen targets for ICU quality improvement or education programs-new ideas for quality improvement were generated and greater attention paid to detail in clinical care. (2) Creating a new role for survivors in the ICU-former patients and family members adopted an advocacy or peer volunteer role. (3) Inviting critical care providers to the post-ICU program to educate, sensitize, and motivate them-clinician peers and trainees were invited to attend as a helpful learning strategy to gain insights into post-ICU care requirements. (4) Changing clinician's own understanding of patient experience-there appeared to be a direct individual benefit from working in post-ICU programs. (5) Improving morale and meaningfulness of ICU work-this was achieved by closing the feedback loop to ICU clinicians regarding patient and family outcomes. CONCLUSIONS: The follow-up of patients and families in post-ICU care settings is perceived to improve care within the ICU via five key mechanisms. Further research is required in this novel area.

- Abstract
UNLABELLED: To use experience-based co-design to identify the key design requirements of a peer support model for critical care survivors; understand the use of the experience-based co-design method from clinician, patients, and family perspectives. DESIGN: Using experience-based co-design, qualitative data about participants' preferences for a peer support model were generated via workshops. Participants' perspectives of experience-based co-design were evaluated with focus groups. SETTING: University-affiliated hospital in Melbourne, Australia. SUBJECTS: Snowball sampling was used to recruit clinicians from across the care spectrum (ICU-community); critical care survivors and nominated family members were recruited using convenience sampling. MEASUREMENTS AND MAIN RESULTS: Consensus on a peer support model was reached through the experience-based co-design process, with the following key themes: 1) socialization and group cohesion; 2) management of potential risks; and 3) individualized needs of patients and families. Evaluation of participants' perspectives of the experience-based co-design method identified five key themes: 1) participation as a positive experience; 2) emotional engagement in the process; 3) learning from patients and family members; 4) feeling heard; and 5) practical challenges of experience-based co-design and readiness to participate. CONCLUSIONS: Experience-based co-design was a feasible approach to developing a peer support model for use with critical care survivors and was well received by participants. Future testing of the co-designed peer support model in a pilot randomized controlled trial will enhance understanding of peer support in critical care and the use of experience-based co-design as a design methodology.

15. Individualizing endpoints in randomized clinical trials to better inform individual patient care: the TARGET proposal

Iwashyna, TJ, Deane, AM, Iwashyna, TJ, and Deane, AM
- Abstract
In practice, critical care practitioners individualize treatments and goals of care for each patient in light of that patient's acute and chronic pathophysiology, as well as their beliefs and values. Yet critical care researchers routinely measure one endpoint for all patients during randomized clinical trials (RCTs), eschewing any such individualization. More recent methodology work has explored the possibility that enrollment criteria in RCTs can be individualized, as can data analysis plans. Here we propose that the specific endpoints of a RCT can be individualized-that is, different patients within a single RCT might have different secondary endpoints measured. If done rigorously and objectively, based on pre-randomization data, such individualization of endpoints may improve the bedside usefulness of information obtained during a RCT, while perhaps also improving the power and efficiency of any RCT. We discuss the theoretical underpinnings of this proposal in light of related innovations in RCT design such as sliding dichotomies. We discuss what a full elaboration of such individualization would require, and outline a pragmatic initial step towards the use of "individualized secondary endpoints" in a large RCT evaluating optimal enteral nutrition targets in the critically ill.

- Abstract
Objectives: We examine the dynamics of patient-sharing relations within an Italian regional community of 35 hospitals serving approximately 1,300,000 people. We test whether interorganizational relations provide individual patients access to higher quality providers of care. Research Design and Methods: We reconstruct the complete temporal sequence of the 3461 consecutive interhospital patientsharing events observed between each pair of hospitals in the community during 2005–2008. We distinguish between transfers occurring between and within different medical specialties. We estimate newly derived models for relational event sequences that allow us to control for the most common forms of network-like dependencies that are known to characterize collaborative relations between hospitals. We use 45-day risk-adjusted readmission rate as a proxy for hospital quality. Results: After controls (eg, geographical distance, size, and the existence of prior collaborative relations), we find that patients flow from less to more capable hospitals. We show that this result holds for patient being shared both between as well as within medical specialties. Nonetheless there are strong and persistent other organizational and relational effects driving transfers. Conclusions: Decentralized patient-sharing decisions taken by the 35 hospitals give rise to a system of collaborative interorganizational arrangements that allow the patient to access hospitals delivering a higher quality of care. This result is relevant for health care policy because it suggests that collaborative relations between hospitals may produce desirable outcomes both for individual patients, and for regional health care systems.

- Abstract
OBJECTIVE: : Interhospital transfer of critically ill patients is a common part of their care. This article sought to review the data on the current patterns of use of interhospital transfer and identify systematic barriers to optimal integration of transfer as a mechanism for improving patient outcomes and value of care. DATA SOURCE: : Narrative review of medical and organizational literature. SUMMARY: : Interhospital transfer of patients is common, but not optimized to improve patient outcomes. Although there is a wide variability in quality among hospitals of nominally the same capability, patients are not consistently transferred to the highest quality nearby hospital. Instead, transfer destinations are selected by organizational routines or non-patient-centered organizational priorities. Accomplishing a transfer is often quite difficult for sending hospitals. But once a transfer destination is successfully found, the mechanics of interhospital transfer now appear quite safe. CONCLUSION: : Important technological advances now make it possible to identify nearby hospitals best able to help critically ill patients, and to successfully transfer patients to those hospitals. However, organizational structures have not yet developed to insure that patients are optimally routed, resulting in potentially significant excess mortality. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: Intensive care unit beds are limited, yet few guidelines exist for triage of patients to the intensive care unit, especially patients at low risk for mortality. The frequency with which low-risk patients are admitted to intensive care units in different hospitals is unknown. Our objective was to assess variation in the use of intensive care for patients with diabetic ketoacidosis, a common condition with a low risk of mortality.Design: Observational study using the New York State In-patient Database (2005-2007).Setting: One hundred fifty-nine New York State acute care hospitals.Patients: Fifteen thousand nine hundred ninety-four adult (≥ 18) hospital admissions with a primary diagnosis of diabetic ketoacidosis (International Classification of Diseases, Ninth Revision, Clinical Modification 250.1x).Interventions: None.Measurements and Main Results: We calculated reliability- and risk-adjusted intensive care unit utilization, hospital length of stay, and mortality. We identified hospital-level factors associated with increased likelihood of intensive care unit admission after controlling patient characteristics using multilevel, mixed-effects logistic regression analyses; we assessed the amount of residual variation in intensive care unit utilization using the intraclass correlation coefficient. Use of intensive care for diabetic ketoacidosis patients varied widely across hospitals (adjusted range: 2.1% to 87.7%), but was not associated with hospital length of stay or mortality. After multilevel adjustment, hospitals with a high volume of diabetic ketoacidosis admissions admitted diabetic ketoacidosis patients to the intensive care unit less often (odds ratio 0.40, p = .002, highest quintile compared to lowest), whereas hospitals with higher rates of intensive care unit utilization for all nondiabetic ketoacidosis in-patients admitted diabetic ketoacidosis patients to the intensive care unit more frequently (odds ratio 1.31, p = .001, for each additional 10% increase). In the multilevel model, more than half (58%) of the variation in the intensive care unit admission practice attributable to hospitals remained unexplained.Conclusions: We observed variations across hospitals in the use of intensive care for diabetic ketoacidosis patients that was not associated with differences in-hospital length of stay or mortality. Institutional practice patterns appear to impact admission decisions and represent a potential target for reduction of resource utilization in higher use institutions.

- Abstract
Rationale: Survivors of critical illness suffer significant limitations and disabilities.Objectives: Ascertain whether severe sepsis is associated with increased risk of so-called geriatric conditions (injurious falls, low body mass index [BMI], incontinence, vision loss, hearing loss, and chronic pain) and whether this association is measured consistently across three different study designs.Methods: Patients with severe sepsis were identified in the Health and Retirement Study, a nationally representative cohort interviewed every 2 years, 1998 to 2006, and in linked Medicare claims. Three comparators were used to assess an association of severe sepsis with geriatric conditions in survivors: the prevalence in the United States population aged 65 years and older, survivors' own pre-sepsis levels assessed before hospitalization, or survivors' own pre-sepsis trajectory.Measurements and Main Results: Six hundred twenty-three severe sepsis hospitalizations were followed a median of 0.92 years. When compared with the 65 years and older population, surviving severe sepsis was associated with increased rates of low BMI, injurious falls, incontinence, and vision loss. Results were similar when comparing survivors to their own pre-sepsis levels. The association of low BMI and severe sepsis persisted when controlling for patients' pre-sepsis trajectories, but there was no association of severe sepsis with injurious falls, incontinence, vision loss, hearing loss, and chronic pain after such controls.Conclusions: Geriatric conditions are common after severe sepsis. However, severe sepsis is associated with increased rates of only a subset of geriatric conditions, not all. In studying outcomes after acute illness, failing to measure and control for both preillness levels and trajectories may result in erroneous conclusions. [ABSTRACT FROM AUTHOR]- Published

- Abstract
OBJECTIVES: To determine whether insurance coverage and race are associated with long-term acute care hospital utilization in critically ill patients requiring mechanical ventilation. DESIGN: Retrospective cohort study. SETTING: Nonfederal Pennsylvania hospital discharges from 2004 to 2006. PATIENTS: Eligible patients were aged 18 yrs or older, of white or black race, and underwent mechanical ventilation in an intensive care unit during their hospital stay. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We used multivariable logistic regression with hospital-level random effects to determine the independent association between discharge to long-term acute care hospital, insurance status, and race after appropriate controls, including a chart-based measure of severity of illness. The primary outcome measure was discharge to long-term acute care hospital. Of 66,233 eligible patients, 84.7% were white and 15.3% were black. More white patients than black patients had commercial insurance (23.4% vs. 14.9%) compared to Medicaid (10.6% vs. 29.7%) or no insurance (1.3% vs. 2.2%). Long-term acute care hospital transfer occurred in 5.0% of patients. On multivariable analysis in patients aged younger than 65 yrs, black patients were significantly less likely to undergo long-term acute care hospital transfer (odds ratio, 0.71; p = .003), as were patients with Medicaid vs. commercial insurance (odds ratio, 0.17; p < .001). Analyzing race and insurance together and accounting for hospital-level effects, patients with Medicaid were still less likely to undergo long-term acute care hospital transfer (odds ratio, 0.18; p < .001), but race effects were no longer present (odds ratio, 1.06; p = .615). No significant race effects were seen in the Medicare-eligible population aged 65 yrs or older (odds ratio for transfer to long-term acute care hospital, 0.93; p = .359). CONCLUSIONS: Differences in long-term acute care hospital utilization after critical illness appear driven by insurance status and hospital-level effects. Racial variation in long-term acute care hospital use is not seen after controlling for insurance status and is not seen in a group with uniform insurance coverage. Differential access to postacute care may be minimized by expanding commercial or Medicare insurance availability and standardizing long-term acute care admission criteria across hospitals.

- Abstract
Rationale: Lack of health insurance maybe an independent risk factor for mortality and differential treatment in critical illness.Objectives: To determine whether uninsured critically ill patients had differences in 30-day mortality and critical care service use compared with those with private insurance and to determine if outcome variability could be attributed to patient-level or hospital-level effects.Methods: Retrospective cohort study using Pennsylvania hospital discharge data with detailed clinical risk adjustment, from fiscal years 2005 and 2006, consisting of 167 general acute care hospitals, with 138,720 critically ill adult patients 64 years of age or younger.Measurements and Main Results: Measurements were 30-day mortality and receipt of five critical care procedures. Uninsured patients had an absolute 30-day mortality of 5.7%, compared with 4.6% for those with private insurance and 6.4% for those with Medicaid. Increased 30-day mortality among uninsured patients persisted after adjustment for patient characteristics (odds ratio [OR], 1.25 for uninsured vs. insured; 95% confidence interval [CI], 1.04–1.50) and hospital-level effects (OR, 1.26; 95% CI, 1.05–1.51). Compared with insured patients, uninsured patients had decreased risk-adjusted odds of receiving a central venous catheter (OR, 0.84; 95% CI,0.72–0.97), acute hemodialysis (OR, 0.59; 95% CI, 0.39–0.91), and tracheostomy (OR, 0.43; 95% CI, 0.29–0.64).Conclusions: Lack of health insurance is associated with increased 30-day mortality and decreased use of common procedures for the critically ill in Pennsylvania. Differences were not attributable to hospital-level effects, suggesting that the uninsured have a higher mortality and receive fewer procedures when compared with privately insured patients treated at the same hospitals.

- Abstract
RATIONALE: General intensive care units (ICUs) provide care across a wide range of diagnoses, whereas specialty ICUs provide diagnosis-specific care. Risk-adjusted outcome differences across such units are unknown. OBJECTIVES: To determine the association between specialty ICU care and the outcome of critical illness. METHODS: We conducted a retrospective cohort study design analyzing patients admitted to 124 ICUs participating in the Acute Physiology and Chronic Health Evaluation IV from January 2002 to December 2005. We examined 84,182 patients admitted to specialty and general ICUs with an admitting diagnosis or procedure of acute coronary syndrome, ischemic stroke, intracranial hemorrhage, pneumonia, abdominal surgery, or coronary-artery bypass graft surgery. ICU type was determined by a local data coordinator at each site. Patients were classified by admission to a general ICU, a diagnosis-appropriate ('ideal') specialty ICU, or a diagnosis-inappropriate ('non-ideal') specialty ICU. The primary outcomes were in-hospital mortality and ICU length of stay. MEASUREMENTS AND MAIN RESULTS: After adjusting for important confounders, there were no significant differences in risk-adjusted mortality between general versus ideal specialty ICUs for all conditions other than pneumonia. Risk-adjusted mortality was significantly greater for patients admitted to non-ideal specialty ICUs. There was no consistent effect of specialization on length of stay for all patients or for ICU survivors. CONCLUSIONS: Ideal specialty ICU care appears to offer no survival benefit over general ICU care for select common diagnoses. Non-ideal specialty ICU care (i.e., 'boarding') is associated with increased risk-adjusted mortality. [ABSTRACT FROM AUTHOR]

- Abstract
PURPOSE: We examined differences in hospice use rates among blacks and whites and investigated trends in racial differences in hospice patients during the period 1992 through 2000. We tested differences in length of hospice survival from hospice enrollment to death between black and white patients during this period.METHODS: We analyzed data from the 1991-2000 Underlying and Multiple Cause-of-Death Files and the 1992-2000 National Home and Hospice Care Surveys using z tests, chi tests, and Cox regression models.RESULTS: Compared with 1992, the hospice use rate doubled for white patients (P < 0.0001) and increased almost 4-fold for black patients (P < 0.0001) in 2000. Hospice use rates among black patients were significantly lower than those among white patients from 1992 to 1994 but not from 1996 to 2000. Black hospice patients discharged throughout the 1990s were more likely to be younger, have Medicaid-only as their payment source, and have HIV/AIDS than their white counterparts. Black hospice patients were more likely to be referred by hospitals than white hospice patients during 1996 to 2000. Throughout the 1990s, length of hospice survival did not significantly differ between black and white hospice patients after adjusting for covariates.CONCLUSIONS: Hospice use rates significantly increased for both whites and black patients. Black patients had lower hospice use rates than white patients from 1992 to 1994, but not from 1996 to 2000, which may reflect the diffusion of hospice care to black patients with the rapid growth in hospice programs. Despite differences in patient characteristics, the length of hospice survival was similar among both groups. Future research is needed to assess whether racial disparities exist in quality of hospice care. [ABSTRACT FROM AUTHOR]

- Abstract
Despite its expense and importance, it is unknown how common critical care use is. We describe longitudinal patterns of critical care use among a nationally representative cohort of elderly patients monitored from the onset of common serious illnesses. A retrospective population-based cohort study of elderly patients in fee-for-service Medicare is used, with 1,108,060 Medicare beneficiaries at least 68 years of age and newly diagnosed with serious illnesses: 1 of 9 malignancies, stroke, congestive heart failure, hip fracture, or myocardial infarction. Medicare inpatient hospital claims from diagnosis until death (65.1%) or fixed-right censoring (more than 4 years) were reviewed. Distinct hospitalizations involving critical care use (intensive care unit or critical care unit) were counted and associated reimbursements were assessed; repeated use was defined as five or more such hospitalizations. Of the cohort, 54.9% used critical care at some time after diagnosis. Older patients were much less likely to ever use critical care (odds ratio, 0.31; comparing patients more than 90 years old with those 68-70 years old), even after adjustment. A total of 31,348 patients (2.8%) were repeated users of critical care; they accounted for 3.6 billion dollars in hospital charges and 1.4 billion dollars in Medicare reimbursement. We conclude that critical care use is common in serious chronic illness and is not associated solely with preterminal hospitalizations. Use is uneven, and a minority of patients who repeatedly use critical care account for disproportionate costs. [ABSTRACT FROM AUTHOR]

- Abstract
Despite suggestive evidence, there has been no adequately powered systematic study of the ways in which marital status influences health care consumption. Using a novel data set of 609016 newly diagnosed, seriously ill elderly individuals in the USA, and employing hierarchical linear models, we look at differences in the experience of hospitalization as a function of marital status. We find that the married consistently use higher quality hospitals and have shorter lengths of stay. On the other hand, the married and the widowed appear to receive similar quality care once they are in the hospital. Marital status thus has a substantial impact on the health care obtained by the elderly. We suggest that these patterns are most consistent with spouses exerting their benefits by functioning as higher-order decision-makers than as home health assistants. [ABSTRACT FROM AUTHOR]

- Abstract
Alternative ways of caring for seriously ill patients might have implications not only for patients' own outcomes, but also, indirectly, for the health outcomes of their family members. Clinical observation suggests that patients who die 'good deaths' may impose less stress on their spouses. Consequently, we sought to assess whether hospice use by a decedent is associated with decreased risk of death in surviving, bereaved spouses. We conducted a matched retrospective cohort study involving a population-based sample of 195,553 elderly couples in the USA. A total of 30,838 couples where the decedent used hospice care were matched using the propensity score method to 30,838 couples where the decedent did not use hospice care. Our principal outcome of interest was the duration of survival of bereaved widow/ers. After adjustment for other measured variables, 5.4% of bereaved wives died by 18 months after the death of their husband when their deceased husband did not use hospice and 4.9% died when their deceased husband did use hospice, yielding an odds ratio (OR) of 0.92 (95% CI: 0.84-0.99) in favor of hospice use. Similarly, whereas 13.7% of bereaved husbands died by 18 months when their deceased wife did not use hospice, 13.2% died when their deceased wife did use hospice, yielding an OR of 0.95 (95% CI: 0.84-1.06) in favor of hospice use. Our findings suggest a possible beneficial impact of hospice--as a particularly supportive type of end-of-life care--on the spouses of patients who succumb to their disease. Hospice care might attenuate the ordinarily increased mortality associated with becoming widowed. This effect is present in both men and women, but it is statistically significant and possibly larger in bereaved wives. The size of this effect is comparable to the reductions in the risk of death seen in a variety of other modifiable risk factors in women. Health care may have positive, group-level health 'externalities': it may affect the health not only of patients but also of patients' family members. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Monovalent COVID-19 vaccines targeting the XBB.1.5 Omicron variant were introduced in September 2023. In the absence of randomized controlled trials demonstrating their efficacy, information on real-world vaccine effectiveness (VE) is needed., Objective: To determine XBB.1.5 COVID-19 VE and the extent to which it declines over time., Design: Target trial emulation., Setting: U.S. Veterans Health Administration., Participants: Eligible XBB.1.5 vaccine recipients were matched 1:1 to unvaccinated persons in 7 sequential biweekly trials with enrollment from 2 October 2023 through 3 January 2024., Intervention: XBB.1.5 COVID-19 vaccination versus no XBB.1.5 vaccination., Measurements: Outcomes were ascertained through 10 May 2024 and included any positive result on a SARS-CoV-2 test from day 10 after the matched index date, subsequent hospitalization within 1 day before or 10 days after the positive result, or death within 30 days after the positive result. Vaccine effectiveness was estimated as 100 × (1 - risk ratio)., Results: Participants (91.3% male; mean age, 69.9 years) included 587 137 pairs of vaccinated and matched unvaccinated persons. Over a mean follow-up of 176 days (range, 118 to 211 days), VE was -3.26% (95% CI, -6.78% to -0.22%) against documented SARS-CoV-2 infection, 16.64% (CI, 6.47% to 25.77%) against SARS-CoV-2-associated hospitalization, and 26.61% (CI, 5.53% to 42.32%) against SARS-CoV-2-associated death. When estimated at 60, 90, and 120 days, respectively, VE against documented infection (14.21%, 7.29%, and 3.15%), hospitalization (37.57%, 30.84%, and 25.25%), or death (54.24%, 44.33%, and 30.25%) showed substantial waning., Limitation: Potential for residual confounding and incomplete capture of COVID-19 vaccination and SARS-CoV-2-related outcomes., Conclusion: COVID-19 vaccines targeting the XBB.1.5 variant of Omicron were not effective in preventing infection and had relatively low VE against hospitalization and death, which declined rapidly over time., Primary Funding Source: U.S. Department of Veterans Affairs., Competing Interests: Disclosures: Disclosure forms are available with the article online.

- Abstract
Rationale: Early identification of intensive care unit (ICU) patients likely to benefit from specialist palliative care could reduce the time such patients spend in the ICU receiving care inconsistent with their goals. Objectives: To evaluate the real-world effects of early screening for palliative care criteria in a medical ICU. Methods: We performed a retrospective cohort study in adults admitted to the ICU using a causal inference approach with instrumental variable analysis. The intervention consisted of screening ICU admissions for palliative care trigger conditions and, if present, offering specialist palliative care consultation, which could be accepted or declined by the ICU. We evaluated specialist palliative care use in pre and postimplementation cohorts from the year before and after screening implementation began (October 2022). In the postimplementation cohort, we compared use of specialist palliative care in those who received early screening versus not. We then estimated the effect of early screening on the primary outcome of days to do-not-resuscitate (DNR) code status or ICU discharge, with death without a DNR order placed at the 99th percentile of the days to DNR or ICU discharge distribution. Secondary outcomes included: DNR order, ICU and hospital lengths of stay, hospice discharge, and mortality metrics. To address unmeasured confounding, we used two-stage least-squares instrumental variables analysis. The instrument, which predicts early screening, comprised weekend versus weekday admission and number of patients meeting palliative care criteria on a patient's ICU Days 1 and 2. Results: Among 1,282 postimplementation admissions, 626 (45%) received early screening, and 398 (28%) received specialty palliative consultation. Early receipt of specialist palliative care was higher in patients who received early screening versus not (17% vs. 1%; P < 0.001), and overall use of specialty palliative care was higher after versus before screening implementation (28% vs. 15%; P < 0.001). In the postimplementation cohort, there were no statistically significant effects of early screening on the primary outcome of days to DNR or ICU discharge (15% relative increase; 95% confidence interval, -11% to +48%) or other secondary outcomes. Conclusions: Despite significantly increased specialty palliative care consultation, there was no evidence that early screening for palliative care criteria affected time to DNR/ICU discharge or other secondary outcomes.

- Abstract
Background: The Treatment of Mechanically Ventilated Adults with Early Activity and Mobilisation (TEAM) trial reported a higher occurrence of adverse events with greater mobilisation. However, their timing and nature remained unexplored. We conducted an in-depth exploration of such events., Objective: The purpose of this paper is to thoroughly examine the timing and characteristics of adverse events reported within the TEAM trial., Methods: Adverse event data were collected daily in real time. Categorical data were compared using the Fisher's exact test. The relationship between adverse events and patient survival was analysed using a Cox-regression frailty model., Results: Overall, 37 out of 371 patients (10.0%) in the early mobilisation group and 16 out of 370 patients (4.3%) in the usual care group experienced adverse events, with 71 events in the early mobilisation group compared to 24 events in the usual care group. The most common adverse events were altered blood pressure in 21 out of 53 patients (39.6%), arrhythmia in 17 out of 53 patients (32.1%), and oxygen desaturation in nine of 53 patients (17.0%). Patients with an adverse event were more likely to have congestive heart failure (absolute percentage difference: 16.1, 95% confidence interval [CI]: 6.1 to 26.1), peripheral vascular disease (absolute percentage difference: 6.4, 95% CI: 1.3 to 11.5), heart attack (absolute percentage difference: 13.5, 95% CI: 5.9 to 21.1), or stroke (absolute percentage difference: 9.3, 95% CI: 3.5 to 15.1). Adverse events occurred at a median of 4 days with early mobilisation and 7 days with usual care. There was no significant difference in survival for patients who experienced an adverse event compared to those without an adverse event., Conclusion: Adverse events were more common in patients randomised to early active mobilisation, were cardiovascular and respiratory in nature, tended to occur earlier with active mobilisation, and cardiovascular comorbidities were more common in such patients. This information can help guide future studies in this field., Trial Registration: TEAM ClinicalTrials.gov number, NCT03133377, registered 28 April 2017., Competing Interests: Conflict of interest The authors declare that they have no competing interests., (Copyright © 2024 Australian College of Critical Care Nurses Ltd.

- Abstract
Objectives: Hispanic individuals comprise one-fifth of the U.S. population and Hispanic patients with acute hypoxemic respiratory failure (AHRF) experience higher odds of death compared with non-Hispanic White patients. Representation of Hispanic patients in clinical trials for respiratory failure is critical to address this inequity. We conducted a systematic review to examine the inclusion of Hispanic patients in randomized controlled trials for AHRF and assessed language as a potential barrier to enrollment., Data Sources: National Library of Medicine PubMed, Elsevier Embase, and Cochrane Central Register of Controlled Trials databases through January 2024., Study Selection: Randomized controlled trials assessing AHRF interventions enrolling U.S. patients receiving mechanical ventilation, noninvasive mechanical ventilation, or high-flow nasal cannula were included. The systematic review was registered prospectively through PROSPERO (CRD42023437828)., Data Extraction: Two authors independently screened studies and extracted data for each included study., Data Synthesis: Ninety-four trials published from 1975 to 2023 were included; 33.0% (n = 31) of studies reported ethnicity, and 11.2% of participants in studies reporting race or ethnicity (1,320/11,780) were identified as Hispanic. The proportion of Hispanic-identified participants was significantly lower than the U.S. Hispanic population from 1996 to 2019 (p < 0.01). Starting in 2020, the proportion of Hispanic-identified participants was significantly higher than the U.S. population (27.8% vs. 19.1%; p < 0.01). Two studies (4.9%) reporting race or ethnicity excluded non-English speaking participants; the remainder did not specify language requirements for enrollment., Conclusions: Hispanic-identified individuals were underrepresented in trials for AHRF until 2020 when Hispanic patient representation increased during COVID-19. Exclusion of participants who do not speak English may represent a barrier to trial enrollment., Competing Interests: The authors have disclosed that they do not have any potential conflicts of interest.

- Abstract
Background: Continuing data on racial bias in pulse oximeters and artificial intelligence have sparked calls for health systems to drive innovation against racial bias in health care device and artificial intelligence markets by incorporating equity concerns explicitly into purchasing decisions., Research Question: How do health care purchasing professionals integrate equity concerns into purchasing decision-making?, Study Design and Methods: Between August 2023 and March 2024, we conducted semistructured interviews via videoconferencing with health care purchasing professionals about purchasing processes for pulse oximeters and other devices-and whether and where equity concerns arise in decision-making. An abductive approach was used to analyze perspectives on how equity and disparity concerns currently are integrated into health care purchasing decision-making. Health care purchasing professionals (N = 30) worked in varied supply chain roles for various health systems and supply chain support and consulting companies across the United States., Results: Health care purchasing professionals described limited considerations of equity in current purchasing processes. They described some receptivity to diversity, equity, and inclusion initiatives, largely focused on diversifying suppliers rather than ensuring that devices and products functioned equitably. Respondents reported that they depended on clinician partners to raise and delineate requirements for equitable performance. Respondents also depicted current sources of evidence used in making purchasing decisions as providing limited information about equitable performance and that large contracts, including with group purchasing organizations, may limit purchasing options., Interpretation: Health system purchasing professionals suggested interest and some nascent successes in diversity, equity, and inclusion considerations in health system purchasing processes, including diverse supplier initiatives, but also expressed a need for strong clinical partnership to ensure equitable performance. Explicit approaches for incorporating equitable performance into health care purchasing likely are needed., Competing Interests: Financial/Nonfinancial Disclosures The authors have reported to CHEST the following: K.

- Abstract
Objective: Rapid vital sign assessment, including temperature measurement, is critical among pediatric patients presenting to the emergency department (ED). While error rates in temporal thermometry are well documented, the potential for differential error rates by demographics is not well established. Our objective was to evaluate error rates of temporal thermometers by demographic variables, specifically race and age, among pediatric patients in the ED., Methods: Pediatric patients (≤18 years old) identified as either Black or White in the medical record presenting to the ED between January 2020 and December 2022 who received at least one paired temperature measurement (temporal and oral/rectal temperature within 30 minutes) were included. Rates of discordance by demographic characteristics were then evaluated. Secondarily, we explored the characteristics of patients who received temporal thermometry only., Results: The final population included 1526 paired temperatures (1412 patients). Among all paired measurements, 26% had discordant measurements (25% in Black patients vs 26% in White patients). In the final adjusted model, children aged ≤12 years old were found to have 2-3 times higher odds of discordance than children >12 years old. Black patients were statistically significantly more likely to receive a temporal thermometer measurement only (adjusted odds ratio [aOR] 1.27, 95% confidence interval [CI]: 1.22, 1.33), even when controlling for fever-related chief complaints., Conclusions: Age ≤12 years old was associated with increased odds of missed fever by temporal thermometry. In our secondary analysis, Black patients were found to be more likely to receive temporal thermometry only. These findings highlight the need for consistent, accurate measurement protocols among pediatric patients., 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 © 2025 Academic Pediatric Association.

- Abstract
Purpose: Federal research grants provide support for the indirect costs (IDCs) of research infrastructure that are not specific to particular research projects but are nonetheless essential to enable research. Institutions independently negotiate IDC rates. The authors sought to identify whether inequities exist in negotiated IDC rates between historically Black colleges and universities (HBCUs) and other universities (non-HBCUs)., Method: In 2023, the authors analyzed mean negotiated IDC rates between the top 20 HBCUs (in fiscal year [FY] 2021 research expenditures) and 3 non-HBCU comparison groups: the top 40 non-HBCUs in FY 2021 research expenditures, metropolitan statistical area (MSA)-matched non-HBCUs (among the top 200 institutions by FY 2021 research expenditures), and FY 2021 research expenditure-matched non-HBCUs., Results: The authors found that the top 20 HBCUs' mean IDC rates (50.0%) were, after adjustment, 8.5 percentage points (95% confidence interval [CI], 5.7-11.2) lower than those of the top 40 non-HBCUs (58.5%). The mean IDC rates of top HBCUs (n = 14, 48.4%) were, after adjustment, 6.3 percentage points (95% CI, 3.1-9.4) lower than those of MSA-matched non-HBCUs (n = 23, 55.3%). There was no statistically significant difference in the mean IDC rates between the top 20 HBCUs (50.0%) and expenditure-matched non-HBCUs (n = 31; 48.2%)., Conclusions: Inequities in negotiated IDC rates between top HBCUs and non-HBCUs likely both reflect and may contribute to the persistence of institution-level inequities in federally funded research. Proactive investments in HBCUs' research infrastructures are likely needed to ameliorate these funding inequities and support the role of HBCUs in providing opportunity for underrepresented groups in biomedical sciences., (Copyright © 2024 the Association of American Medical Colleges.)

- Abstract
Background: Peer support is a promising intervention to mitigate post-ICU disability, however there is a paucity of rigorously designed studies., Objectives: The objective of this study was to establish feasibility of an in-person, co-designed, peer-support model., Methods: Prospective, randomised, adaptive, single-centre pilot trial with blinded outcome assessment, conducted at a university-affiliated hospital in Melbourne, Australia. Intensive care unit survivors (and their nominated caregiver, where survivor and caregiver are referred to as a dyad), >18 years of age, able to speak and understand English and participate in phone surveys, were eligible. Participants were randomised to the peer-support model (six sessions, fortnightly) or usual care (no follow-up or targeted information). Two sequential models were piloted: 1. Early (2-3 weeks post hospital discharge) 2. Later (4-6 weeks post hospital discharge). Primary outcome was feasibility of implementation measured by recruitment, intervention attendance, and outcome completion. Secondary outcomes included post-traumatic stress and social support., Results: Of the 231 eligible patients, 80 participants were recruited. In the early model we recruited 38 participants (28 patients, 10 carers; 18 singles, 10 dyads), with an average (standard deviation) age of 60 (18) years; 55 % were female. Twenty-two participants (58 %) were randomised to intervention. Participants in the early intervention model attended a median (interquartile range) of 0 (0-1) sessions (total 24 sessions), with 53% (n = 20) completing the main secondary outcome of interest (Impact of Event Scale) at the baseline and 37 % (n = 14) at the follow-up. For the later model we recruited 42 participants (32 patients, 10 carers; 22 singles, 10 dyads), with an average (standard deviation) age of 60.4 (15.4) years; 50 % were female. Twenty-one participants (50 %) were randomised to intervention. The later intervention model attended a median (interquartile range) of 1 (0-5) sessions (total: 44 sessions), with the main secondary outcome impact of events scale (IES-R) completed by 41 (98 %) participants at baseline and 29 (69 %) at follow-up., Conclusions: In this pilot trial, a peer-support model that required in-person attendance delivered in a later posthospital phase of recovery appeared more feasible than an early model. Further research should investigate alternative modes of intervention delivery to improve feasibility (ACTRN12621000737831)., Competing Interests: Conflict of interest K Haines received a SCCM Thrive Award from SCCM to undertake this study.

- Abstract
Rationale: Prone positioning for ⩾16 hours in moderate-to-severe acute respiratory distress syndrome (ARDS) improves survival. However, the optimal duration of proning is unknown. Objectives: To estimate the effect of extended versus standard proning duration on patients with moderate-to-severe coronavirus disease (COVID-19) ARDS. Methods: Data were extracted from a five-hospital electronic medical record registry. Patients who were proned within 72 hours of mechanical ventilation were categorized as receiving extended (⩾24 h) versus standard (16-24 h) proning based on the first proning session length. We used a target trial emulation design to estimate the effect of extended versus standard proning on the primary outcome of 90-day mortality and secondary outcomes of ventilator liberation and intensive care unit (ICU) discharge. Analytically, we used inverse probability of treatment weighted (IPTW) Cox or Fine-Gray regression models. Results: A total of 314 patients were included; 234 received extended proning, and 80 received standard-duration proning. Patients who received extended proning were older, had greater comorbidity, were more often at an academic hospital, and had shorter time from admission to mechanical ventilation. After IPTW, characteristics were well balanced. Unadjusted 90-day mortality in the extended versus standard proning groups was 39% versus 58%. In doubly robust IPTW analyses, we found no significant effects of extended versus standard proning duration on mortality (hazard ratio [95% confidence interval], 0.95 [0.51-1.77]), ventilator liberation (subdistribution hazard, 1.60 [0.97-2.64], or ICU discharge (subdistribution hazard, 1.31 [0.82-2.10]). Conclusions: Using target trial emulation, we found no significant effect of extended versus standard proning duration on mortality, ventilator liberation, or ICU discharge. However, given the imprecision of estimates, further study is justified.
