Decision tree-based rules outperform risk scores for childhood asthma prognosis.

BACKGROUND: There are no widely accepted prognostic tools for childhood asthma; this is in part due to the multifactorial and time-dependent nature of mechanisms and risk factors that contribute to asthma development. Our study objective was to develop and evaluate the prognostic performance of conditional inference decision tree-based rules using the Pediatric Asthma Risk Score (PARS) predictors as an alternative to the existing logistic regression-based risk score for childhood asthma prediction at 7 years in a high-risk population. METHODS: The Canadian Asthma Primary Prevention Study data were used to develop, compare, and contrast the prognostic performance (area under the curve [AUC], sensitivity, and specificity) of conditional inference tree-based decision rules to the pediatric asthma risk score for the prediction of childhood asthma at 7 years. RESULTS: Conditional inference decision tree-based rules have higher prognostic performance (AUC: 0.85; 95% CI: 0.81, 0.88; sensitivity = 47%; specificity = 93%) than the pediatric asthma risk score at an optimal cutoff of ≥6 (AUC: 0.71; 95% CI: 0.67, 0.76; sensitivity = 60%; specificity = 74%). Moreover, the pediatric asthma risk score is not linearly related to asthma risk, and at any given pediatric asthma risk score value, different combinations of its pediatric asthma risk score clinical variables differentially predict asthma risk. CONCLUSION: Conditional inference tree-based decision rules could be a useful childhood asthma prognostic tool, providing an alternative way to identify unique subgroups of at-risk children, and insights into associations and effect mechanisms that are suggestive of appropriate tailored preventive interventions. However, the feasibility and effectiveness of such decision rules in clinical practice is warranted.

Reassessing access to intensive care using an estimate of the population incidence of critical illness.

BACKGROUND: The consistently observed male predominance of patients in intensive care units (ICUs) has raised concerns about gender-based disparities in ICU access. Comparing rates of ICU admission requires choosing a normalizing factor (denominator), and the denominator usually used to compare such rates between subpopulations is the size of those subpopulations. However, the appropriate denominator is the number of people whose medical condition warranted ICU care. We devised an estimate of the number of critically ill people in the general population, and used it to compare rates of ICU admission by gender and income. METHODS: This population-based, retrospective analysis included all adults in the Canadian province of Manitoba, 2004-2015. We created an estimate for the number of critically ill people who warrant ICU care, and used it as the denominator to generate critical illness-normalized rates of ICU admission. These were compared to the usual population-normalized rates of ICU care. RESULTS: Men outnumbered women in ICUs for all age groups; population-normalized male:female rate ratios significantly exceed 0 for every age group, ranging from 1.15 to 2.10. Using critical-illness normalized rates, this male predominance largely disappeared; critically ill men and women aged 45-74 years were admitted in equivalent proportions (critical-illness normalized rate ratios 0.96-1.01). While population-normalized rates of ICU care were higher in lower income strata (p < 0.001), the gradient for critical illness-based rates was reversed (p < 0.001). CONCLUSIONS: Across a 30-year adult age span, the male predominance of ICU patients was accounted for by higher estimated rates of critical illness among men. People in lower income strata had lower critical-illness normalized rates of ICU admission. Our methods highlight that correct inferences about access to healthcare require calculating rates using denominators appropriate for this purpose.

NIAID, NIEHS, NHLBI, and MCAN Workshop Report: The indoor environment and childhood asthma-implications for home environmental intervention in asthma prevention and management.

Environmental exposures have been recognized as critical in the initiation and exacerbation of asthma, one of the most common chronic childhood diseases. The National Institute of Allergy and Infectious Diseases; National Institute of Environmental Health Sciences; National Heart, Lung, and Blood Institute; and Merck Childhood Asthma Network sponsored a joint workshop to discuss the current state of science with respect to the indoor environment and its effects on the development and morbidity of childhood asthma. The workshop included US and international experts with backgrounds in allergy/allergens, immunology, asthma, environmental health, environmental exposures and pollutants, epidemiology, public health, and bioinformatics. Workshop participants provided new insights into the biologic properties of indoor exposures, indoor exposure assessment, and exposure reduction techniques. This informed a primary focus of the workshop: to critically review trials and research relevant to the prevention or control of asthma through environmental intervention. The participants identified important limitations and gaps in scientific methodologies and knowledge and proposed and prioritized areas for future research. The group reviewed socioeconomic and structural challenges to changing environmental exposure and offered recommendations for creative study design to overcome these challenges in trials to improve asthma management. The recommendations of this workshop can serve as guidance for future research in the study of the indoor environment and on environmental interventions as they pertain to the prevention and management of asthma and airway allergies.

Rates of readmission and death associated with leaving hospital against medical advice: a population-based study.

BACKGROUND: Leaving hospital against medical advice may have adverse consequences. Previous studies have been limited by evaluating specific types of patients, small sample sizes and incomplete determination of outcomes. We hypothesized that leaving hospital against medical advice would be associated with increases in subsequent readmission and death. METHODS: In a population-based analysis involving all adults admitted to hospital and discharged alive in Manitoba from Apr. 1, 1990, to Feb. 28, 2009, we evaluated all-cause 90-day mortality and 30-day hospital readmission. We used multivariable regression, adjusted for age, sex, socioeconomic status, year of hospital admission, patient comorbidities, hospital diagnosis, past frequency of admission to hospital, having previously left hospital against medical advice and data clustering (patients with multiple admissions). For readmission, we assessed both between-person and within-person effects of leaving hospital against medical advice. RESULTS: Leaving against medical advice occurred in 21 417 of 1 916 104 index hospital admissions (1.1%), and was associated with higher adjusted rates of 90-day mortality (odds ratio [OR] 2.51, 95% confidence interval [CI] 2.18-2.89), and 30-day hospital readmission (within-person OR 2.10, CI 1.99-2.21; between-person OR 3.04, CI 2.79-3.30). In our additional analyses, elevated rates of readmission and death associated with leaving against medical advice were manifest within 1 week and persisted for at least 180 days after discharge. INTERPRETATION: Adults who left the hospital against medical advice had higher rates of hospital readmission and death. The persistence of these effects suggests that they are not solely a result of incomplete treatment of acute illness. Interventions aimed at reducing these effects may need to include longitudinal interventions extending beyond admission to hospital.

Epidemiology of critically ill patients in intensive care units: a population-based observational study.

INTRODUCTION: Epidemiologic assessment of critically ill people in Intensive Care Units (ICUs) is needed to ensure the health care system can meet current and future needs. However, few such studies have been published. METHODS: Population-based analysis of all adult ICU care in the Canadian province of Manitoba, 1999 to 2007, using administrative data. We calculated age-adjusted rates and trends of ICU care, overall and subdivided by age, sex and income. RESULTS: In 2007, Manitoba had a population of 1.2 million, 118 ICU beds in 21 ICUs, for 9.8 beds per 100,000 population. Approximately 0.72% of men and 0.47% of women were admitted to ICUs yearly. The age-adjusted, male:female rate ratio was 1.75 (95% CI 1.64 to 1.88). Mean age was 64.5 ± 16.4 years. Rates rose rapidly after age 40, peaked at age 75 to 80, and declined for the oldest age groups. Rates were higher among residents of lower income areas, for example declining from 7.9 to 4.4 per 100,000 population from the poorest to the wealthiest income quintiles (p <0.0001). Rates of ICU admission slowly declined over time, while cumulative yearly ICU bed-days slowly rose; changes were age-dependent, with faster declines in admission rates with older age. There was a high rate of recidivism; 16% of ICU patients had received ICU care previously. CONCLUSIONS: These temporal trends in ICU admission rates and cumulative bed-days used have significant implications for health system planning. The differences by age, sex and socioeconomic status, and the high rate of recidivism require further research to clarify their causes, and to devise strategies for reducing critical illness in high-risk groups.

A population-based analysis of leaving the hospital against medical advice: incidence and associated variables.

BACKGROUND: Prior studies of patients leaving hospital against medical advice (AMA) have been limited by not being population-based or assessing only one type of patient. METHODS: We used administrative data at the Manitoba Centre for Health Policy to evaluate all adult residents of Manitoba, Canada discharged alive from acute care hospitals between April 1, 1990 and February 28, 2009. We identified the rate of leaving AMA, and used multivariable logistic regression to identify socio-demographic and diagnostic variables associated with leaving AMA. RESULTS: Of 1,916,104 live hospital discharges, 21,417 (1.11%) ended with the patient leaving AMA. The cohort contained 610,187 individuals, of whom 12,588 (2.06%) left AMA once and another 2986 (0.49%) left AMA more than once. The proportion of AMA discharges did not change over time. Alcohol and drug abuse was the diagnostic group with the highest proportion of AMA discharges, at 11.71%. Having left AMA previously had the strongest association with leaving AMA (odds ratio 170, 95% confidence interval 156-185). Leaving AMA was more common among men, those with lower average household incomes, histories of alcohol or drug abuse or HIV/AIDS. Major surgical procedures were associated with a much lower chance of leaving the hospital AMA. CONCLUSIONS: The rate of leaving hospital AMA did not systematically change over time, but did vary based on patient and illness characteristics. Having left AMA in the past was highly predictive of subsequent AMA events.

Aeroallergen-related Diseases Predate the Diagnosis of Inflammatory Bowel Disease.

OBJECTIVE: This study aimed to determine whether having a diagnosis of asthma or allergic rhinitis (AR) increased the risk of being diagnosed with inflammatory bowel disease (IBD) and whether there was increased incidence of these diseases after a diagnosis of IBD. DESIGN: This is a retrospective, historical cohort-based study. We used the administrative data of Manitoba Health and the population-based University of Manitoba IBD Epidemiology Database. We used numbers of prescriptions for drugs used to treat asthma and to treat AR to identify diagnoses of asthma and AR, respectively.We calculated relative risks (RRs) to assess incidence of IBD compared with matched controls after diagnoses of asthma and AR and hazard ratios to determine the incidence of asthma and AR after IBD diagnosis. RESULTS: Compared with controls, a diagnosis of asthma or AR preceding a diagnosis of IBD was increased in cases (RR, 1.62; 95% confidence interval [CI], 1.50-1.75; and RR, 2.10; 95% CI, 1.97-2.24) with a similar outcome by subtype of IBD (Crohn's disease vs ulcerative colitis) and by sex. On sensitivity analysis, diagnoses of asthma or AR were comparable when considering at least 5, 10, 15 or 20 drug prescriptions. Persons with IBD were more likely to develop asthma or AR than controls after being diagnosed with IBD (hazard ratio for asthma, 1.31, 95% CI, 1.18-1.45; and hazard ratio for AR, 2.62, 95% CI, 2.45-2.80). CONCLUSIONS: The association between asthma, AR, and IBD suggest the possibility that whatever triggers the onset of these atopic diseases may trigger the onset of IBD as well, and aeroallergens are plausible culprits.

This study demonstrates that a preexisting diagnosis of asthma or allergic rhinitis is associated with an increased risk of subsequently developing IBD. These data reinforce the importance of considering that gastrointestinal complaints in patients with asthma and allergic rhinitis may reflect a possible diagnosis of IBD. It also raises the possibility that aeroallergens may be environmental cause(s) of IBD.

Sedation and analgesia usage in severe pandemic H1N1 (2009) infection: a comparison to respiratory failure secondary to other infectious pneumonias.

BACKGROUND: During the 2009 H1N1 pandemic (pH1N1), patients requiring mechanical ventilation for respiratory failure received high doses of sedation and analgesia. OBJECTIVE: To examine sedation and analgesia use among patients with respiratory failure due to severe pH1N1 infection compared to other infectious pneumonias. METHODS: In this observational cohort study of intensive care unit (ICU) patients with respiratory failure, we compared doses of sedatives and analgesics administered to patients with pH1N1, non-pH1N1 viral pneumonia, and adult respiratory distress syndrome (ARDS) secondary to bacterial pneumonia, on days 1, 3, 7, 14, and 28 of ICU admission. Cumulative drug use, daily drug use, and weight-adjusted medication doses were examined. RESULTS: The study population consisted of 37 patients with pH1N1 infection, 22 patients with non-pH1N1 viral pneumonia, and 46 patients with ARDS secondary to bacterial pneumonia. To achieve similar levels of sedation using the Richmond Agitation Sedation Scale, patients with pH1N1 were administered the highest cumulative median doses of fentanyl (11,230 µg; interquartile range [IQR] 3240-21,000), compared to 2400 µg (IQR 130-7130) in viral pneumonia and 2880 µg (IQR 600-6950) in ARDS (p < 0.001). Patients with pH1N1 were also administered the highest cumulative median doses of midazolam at 820 mg (IQR 330-1160), compared to 160 mg (IQR 20-390) in viral pneumonia and 160 mg (IQR 20-480 mg) in ARDS (p < 0.001). The pH1N1 group received the highest median daily fentanyl and midazolam doses on all study days. The pH1N1 group did not differ significantly in cumulative propofol dose compared with the other 2 study groups. CONCLUSIONS: Sedative and analgesic use may be uniquely higher in critically ill patients with pH1N1 infection compared to patients with other infectious pneumonias. This finding may be important for resource planning in future pandemics. Further study is required to explore the underlying mechanisms for potentially higher sedative and analgesic requirements in this patient population.

High screen time is associated with asthma in overweight Manitoba youth.

OBJECTIVE: Low physical activity and high sedentary behavior are associated with adverse health outcomes, including asthma. The purposes were to (1) determine if low physical activity and/or high screen time increase the risk of asthma and airway hyperresponsiveness (AHR) in youth and (2) determine if weight status modifies these associations. METHODS: This is a prospective cohort study of healthy weight and overweight Canadian youth. In 2003-2005, 723 youth (8.6 ± 0.5 years; 34.0% asthma, 55.9% boys) were recruited from the 1995 Manitoba Prospective Cohort Study. In 2008-2010, 489 returned for follow-up measures (30.9% asthma, 56.6% boys). The primary exposure variables were parent-reported physical activity and screen time at 8-10 years of age. The primary outcome measures were pediatric allergist-defined asthma and AHR defined as the provocative concentration of methacholine required to induce a 20% fall in forced expiratory volume in 1 second (FEV(1)). RESULTS: Low physical activity (≤2 times weekly) was not associated with asthma or AHR. However, high screen time (≥1 hour/day) was associated with a greater odds of asthma at baseline (odds ratio (OR) = 2.01, 95% confidence interval (CI) = 1.20-3.37, p < .01) and follow-up (OR = 2.11, 95% CI = 1.14-3.89, p < .02) versus low screen time. This association was more pronounced among overweight youth (baseline: OR = 3.95, 95% CI = 1.70-9.12, p < .0001; follow-up: OR = 3.22, 95% CI = 1.17-8.86, p < .02). Screen time was not associated with AHR at baseline or follow-up. CONCLUSIONS: High screen time increases the risk of asthma, particularly among overweight youth. Screen time, in addition to physical activity, should be included in clinical assessments of youth with asthma.

"Asthma isn't an excuse, it's just a condition": youths' perceptions of physical activity and screen time.

OBJECTIVE: During puberty, physical activity patterns begin to decline, while sedentary time increases. These changes may be confounded by asthma. The purpose of this study was to gain insight into youths' perceptions of screen time and physical activity by asthma status. METHODS: Four interviews and seven focus groups with boys only or girls only were conducted with 15- to 16-year-old youth enrolled in either of two asthma-focused cohorts in Manitoba, Canada. Using a semi-structured interview guide, youth were asked about their perceptions of physical activity and screen time such as texting, watching television, electronic games, and Internet chatting and about their perceptions of the influence that asthma has on these behaviors. Data were analyzed using thematic coding. RESULTS: Two themes were common to youth with asthma and without asthma: (1) sports are an integral part of youths' lives and (2) screen time is important to youth. Two themes were identified among youth with asthma only: (1) physical activity used to be more difficult and (2) being active and living with asthma. Youth with asthma described physical activity as neither a hindrance to activity nor an excuse for inactivity, although asthma may still present some challenges. They also acknowledged their reliance on screen time for communication and for entertainment. CONCLUSIONS: Youth with asthma believe that physical activity has become increasingly easier as they become older and that being active with asthma, despite its challenges, is a key part of their lives.

Ventilator management for hypoxemic respiratory failure attributable to H1N1 novel swine origin influenza virus.

Novel H1N1 swine origin influenza virus has led to a worldwide pandemic. During the pandemic, a significant number of patients became critically ill primarily because of respiratory failure. Most of these patients required intubation and mechanical ventilation and were treated with conventional modes of mechanical ventilation using a lung-protective strategy with low tidal volumes, plateau pressures <30 to 35 cm H2O, and optimal positive end-expiratory pressure. In some patients with persistent hypoxemia, alternative modes of ventilation, such as high-frequency oscillatory ventilation and airway pressure release ventilation, were used. We review the ventilatory management, recruitment maneuvers, prone positioning, and goals of ventilatory therapy for hypoxemic respiratory failure in general, as well as lessons learned in the management of H1N1-related respiratory failure.

Assessing Symptoms, Concerns, and Quality of Life in Noncancer Patients at End of Life: How Concordant Are Patients and Family Proxy Members?

CONTEXT: It has become commonplace to use family caregivers as proxy responders where patients are unable to provide information about their symptoms and concerns to health care providers. OBJECTIVES: The objective of this study was to determine the degree of concordance between patients' and family members' reports of patient symptoms and concerns at end of life. METHODS: Sample dyads included a mix of patients residing at home, in a nursing home, in a long-term care facility, or in hospice. Diagnoses included patients with amyotrophic lateral sclerosis (n = 75), chronic obstructive pulmonary disease (n = 52), end-stage renal disease (n = 42), and institutionalized, cognitively intact frail elderly (n = 49). Dyads completed the Patient Dignity Inventory (PDI), the modified Structured Interview Assessment of Symptoms and Concerns in Palliative Care, and Graham and Longman's two-item Quality of Life Scale. RESULTS: Concordance was less than 70% for seven of the 25 PDI items, with the lowest concordance (65.1%) for the item "not being able to continue with my usual routines." For all but one PDI item, discordance was in the direction of family members reporting that the patient was worse off than the patient had indicated. Where discordance was observed on the Structured Interview Assessment of Symptoms and Concerns in Palliative Care and Quality of Life Scales, the trend toward family members overreporting patient distress and poor quality of life continued. CONCLUSION: Understanding discordance between patients and family member reports of symptoms and concerns is a valuable step toward minimizing patient and family burden at end of life.

Health-care use among Puerto Rican and African-American children with asthma.

STUDY OBJECTIVES: To compare the rates of emergency department (ED) visits, hospitalizations, hospital days, and outpatient clinic visits for asthma among children in two ethnic minority groups that are disproportionately affected by asthma (Puerto Ricans and African Americans). STUDY DESIGN: This cross-sectional study was part of an asthma intervention program in Hartford, CT, in which 6,554 children were screened for asthma by primary care providers using a parental survey. Medicaid and the supplementary State Children's Health Insurance Plan data about health-care utilization for asthma were obtained for each child for the 12 months preceding completion of the screening survey. RESULTS: Among 2,304 children in whom asthma had been diagnosed, Puerto Ricans had more severe asthma than African Americans. In analyses adjusted for asthma severity and other potential confounders, Puerto Rican children had more clinic visits for asthma (rate ratio [RR], 1.31; 95% confidence interval [CI], 1.12 to 1.53) but spent fewer days in the hospital for asthma (RR, 0.36; 95% CI, 0.24 to 0.53) than African-American children. There were no differences in the rates of ED visits or hospitalizations between the two groups. CONCLUSIONS: Puerto Rican children had more severe asthma but were less likely than African-American children to have prolonged hospitalizations for asthma. This finding may be due to the frequent clinic visits for asthma made by Puerto Rican children. Further research is needed to understand the cultural factors that contribute to different approaches to health-care utilization among ethnic minorities.

Dignity and Distress towards the End of Life across Four Non-Cancer Populations.

OBJECTIVE: The purpose of this study was to identify four non-cancer populations that might benefit from a palliative approach; and describe and compare the prevalence and patterns of dignity related distress across these diverse clinical populations. DESIGN: A prospective, multi-site approach was used. SETTING: Outpatient clinics, inpatient facilities or personal care homes, located in Winnipeg, Manitoba and Edmonton, Alberta, Canada. PARTICIPANTS: Patients with advanced Amyotrophic Lateral Sclerosis (ALS), Chronic Obstructive Pulmonary Disease (COPD), End Stage Renal Disease (ESRD); and the institutionalized alert frail elderly. MAIN OUTCOME MEASURE: In addition to standardized measures of physical, psychological and spiritual aspects of patient experience, the Patient Dignity Inventory (PDI). RESULTS: Between February 2009 and December 2012, 404 participants were recruited (ALS, 101; COPD, 100; ESRD, 101; and frail elderly, 102). Depending on group designation, 35% to 58% died within one year of taking part in the study. While moderate to severe loss of sense of dignity did not differ significantly across the four study populations (4-11%), the number of PDI items reported as problematic was significantly different i.e. ALS 6.2 (5.2), COPD 5.6 (5.9), frail elderly 3.0 (4.4) and ESRD 2.3 (3.9) [p < .0001]. Each of the study populations also revealed unique and distinct patterns of physical, psychological and existential distress. CONCLUSION: People with ALS, COPD, ESRD and the frail elderly face unique challenges as they move towards the end of life. Knowing the intricacies of distress and how they differ across these groups broadens our understanding of end-of-life experience within non-cancer populations and how best to meet their palliative care needs.

Predictors of disease severity in children with asthma in Hartford, Connecticut.

Childhood asthma is a major public health problem in the United States, particularly among minority populations. The aim of our study was to examine the relationship among ethnicity, allergen sensitization, spirometric measures, and asthma severity in children with mild to severe asthma who received their medical care in Hartford, Connecticut. Four hundred thirty-eight children aged 4-18 years who were enrolled in an asthma care program (Easy Breathing) in Hartford and who were referred for spirometry and allergy skin testing participated in this cross-sectional study. Risk factors for increased asthma severity as defined by National Asthma Education and Prevention Program (NAEPP) guidelines were determined using multinomial logistic regression. Of 438 children, 383 (87.4%) had mild to moderate asthma, and 292 (66.7%) had at least one positive skin test to allergens. Forced expiratory volume in 1 sec/forced vital capacity (FEV1/FVC) was significantly decreased in children with severe vs. mild asthma (80.7 vs. 87.3, respectively). In a multivariate analysis, predictors of severe asthma included African-American ethnicity (odds ratio (OR)=3.70, 95% confidence interval (CI)=1.10-12.42), Puerto Rican ethnicity (OR=3.55, 95% CI=1.18-10.67), sensitization to cockroach allergen (OR=4.34, 95% CI=1.73-10.86), and decreased FEV1/FVC (OR for every 1% decrease in FEV1/FVC=1.06, 95% CI=1.02-1.11). In conclusion, among children with asthma in Hartford and its surrounding communities, predictors of disease severity included African-American ethnicity, Puerto Rican ethnicity, sensitization to cockroach allergen, and decreased FEV1/FVC. Our findings suggest that FEV1/FVC is a useful indicator of asthma severity in children.

A population-based observational study of intensive care unit-related outcomes. With emphasis on post-hospital outcomes.

RATIONALE: Many studies of critical illness outcomes have been restricted to short-term outcomes, selected diagnoses, and patients in one or a few intensive care units (ICUs). OBJECTIVES: Evaluate a range of relevant outcomes in a population-based cohort of patients admitted to ICUs. METHODS: Among all adult residents of the Canadian province of Manitoba admitted to ICUs over a 9-year period, we assessed ICU, hospital, 30-day, and 180-day mortality rates; ICU and hospital lengths-of-stay; Post-hospital use of hospital care, ICU care, outpatient physician care, medications, and home care; and Post-hospital residence location. We explored data stratified by age, sex, and separate categories of geocoded income for urban and rural residents. For Post-hospital use variables we compared ICU patients with those admitted to hospitals without the need for ICU care. MEASUREMENTS AND MAIN RESULTS: After ICU admission there was a high initial death rate, which declined between 30 and 180 days and thereafter remained at the lower value. Hospital mortality was 19.0%, with 21.7% dying within 6 months of ICU admission. Women had higher hospital mortality than men (20.8 vs. 17.8%; P = 0.0008). Among urban residents there was a steady gradient of declining hospital mortality with rising income (P < 0.0001). Mean ICU length of stay was 3.96 days, increasing 0.11 d/yr over the study period (P = 0.001); median ICU length of stay was 2.33 days and did not change over time. In the year after ICU care, 41% were rehospitalized, 10% were readmitted to an ICU, 98% had outpatient physician visits, 96% used prescription medications, and 27% used home care services. Although most of these parameters were statistically higher than for hospitalizations not requiring ICU care, differences were generally small. Among hospital survivors, 2.7% were discharged to chronic care facilities, with 2.5% living in such facilities 3 months later. CONCLUSIONS: Post-hospital medical resource use among ICU survivors is substantial, although similar to that after non-ICU hospitalization. Although the fraction of survivors unable to live independently was small, a larger fraction required home care services. Identifying Post-hospital supports needed by ICU survivors can be useful for policy makers and others responsible for healthcare planning.
