Objectives: There are health disparities and inequities in the outcomes of critical illness survivors related to the influence of social determinants of health on recovery. The purpose of this study was to describe the relationship between critical illness recovery and the intermediary social determinants of health in the Canadian context. Because Canadian healthcare is provided within a universal publicly funded system, this analysis sheds light on the role of social determinants of health in the context of universal health services and a relatively robust social safety net., Design: In this qualitative interpretive description study, data from semi-structured interviews with intensive care unit survivors, family caregivers and healthcare providers were analysed using thematic and constant comparative methods., Setting: Western Canadian Hospital serving a population of 900 000 people., Participants: The 74 study participants included 30 patients (mean age 58 years, 18 men and 12 women) and 25 family caregivers (mean age 55 years, 8 men and 17 women), representing 37 cases, as well as 19 healthcare providers., Results: Challenges with employment and finances, home set-up, transportation, food and nutrition, medications and social support complicated and hindered critical illness recovery. Critical illness sequelae also altered these social determinants of health, suggesting a reciprocal relationship. Furthermore, individuals experiencing socioeconomic disadvantage before critical illness described being at a greater disadvantage following their critical illness, which interfered with their recovery and suggests an accumulation of risk for some., Conclusions: Our findings underscore the significant influence of social determinants of health on critical illness recovery, highlighting the importance of creating and evaluating comprehensive approaches to health and well-being that address health inequities., Competing Interests: Competing interests: RCA has received honoraria from Edwards Lifesciences and HLS Therapeutics.

Objective: To evaluate the association between provider religion and religiosity and consensus about end-of-life care and explore if geographical and institutional factors contribute to variability in practice., Methods: Using a modified Delphi method 22 end-of-life issues consisting of 35 definitions and 46 statements were evaluated in 32 countries in North America, South America, Eastern Europe, Western Europe, Asia, Australia and South Africa. A multidisciplinary, expert group from specialties treating patients at the end-of-life within each participating institution assessed the association between 7 key statements and geography, religion, religiosity and institutional factors likely influencing the development of consensus., Results: Of 3049 participants, 1366 (45%) responded. Mean age of respondents was 45 ± 9 years and 55% were females. Following 2 Delphi rounds, consensus was obtained for 77 (95%) of 81 definitions and statements. There was a significant difference in responses across geographical regions. South African and North American respondents were more likely to encourage patients to write advance directives. Fewer Eastern European and Asian respondents agreed with withdrawing life-sustaining treatments without consent of patients or surrogates. While respondent's religion, years in practice or institution did not affect their agreement, religiosity, physician specialty and responsibility for end-of-life decisions did., Conclusions: Variability in agreement with key consensus statements about end-of-life care is related primarily to differences among providers, with provider-level variations related to differences in religiosity and specialty. Geography also plays a role in influencing some end-of-life practices. This information may help understanding ethical dilemmas and developing culturally sensitive end-of-life care strategies., 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.

Objectives: To investigate how the accumulation of deficits traditionally related and not traditionally related to dementia predicts dementia and mortality., Design: A retrospective cohort study with up to 9 years of follow-up., Setting and Participants: Long-term care residents aged ≥65 with or without dementia., Methods: Frailty indices based on health deficit accumulation were constructed. The FI-t consisted of 27 deficits traditionally related to dementia; the FI-n consisted of 27 deficits not traditionally related to dementia; the FI-a consisted of all 54 deficits taken from the FI-t and the FI-n., Results: In this long-term care sample (n = 29,758; mean age = 84.6 ± 8.0; 63.8% female), 91% of the residents had at least 1 impairment in activities of daily living, 61% had a diagnosis of dementia, and the vast majority were frail (53% had FI-a > 0.2). Residents with dementia had a higher FI-t compared with those without dementia (0.278 ± 0.110 vs. 0.272 ± 0.108), whereas residents without dementia had a higher FI-n (0.143 ± 0.082 vs. 0.136 ± 0.079). Within 9 years, 97% of the sample had died; a 0.01 increase of the FI-a was associated with a 4% increase of the mortality risk, adjusting for age, sex, admission year, stay length, and dementia type. Residents who developed dementia after admission to long-term care had higher baseline FI-t and FI-a (P's < .003) than those who remained without dementia., Conclusions and Implications: Frailty is highly prevalent in older adults living in long-term care, irrespective of the presence or absence of dementia. Accumulation of deficits, either traditionally related or unrelated to dementia, is associated with risks of death and dementia, and more deficits increases the probability. Our findings have implications for improving the quality of care of older adults in long-term care, by monitoring the degree of frailty at admission, managing distinct needs in relation to dementia, and enhancing frailty level-informed care and services., Competing Interests: Disclosure The authors declare no conflicts of interest., (Copyright © 2024 The Authors.

Objective: Associations between low socioeconomic status (SES) and poor health outcomes have been demonstrated in a variety of conditions. However, the relationship in patients with sepsis is not well described. We investigated the association of lower household income with in-hospital mortality in patients with sepsis across the United States., Methods: Retrospective nationwide cohort analysis utilizing the Nationwide Inpatient Sample (NIS) from 2011. Patients aged 18 years or older with sepsis were included. Socioeconomic status was approximated by the median household income of the zip code in which the patient resided. Multivariate logistic modeling incorporating a validated illness severity score for sepsis in administrative data was performed., Results: A total of 8 023 590 admissions from the 2011 NIS were examined. A total of 671 858 patients with sepsis were included in the analysis. The lowest income residents compared to the highest were younger (66.9 years, standard deviation [SD] = 16.5 vs 71.4 years, SD = 16.1, P < .01), more likely to be female (53.5% vs 51.9%, P < .01), less likely to be white (54.6% vs 76.6%, P < .01), as well as less likely to have health insurance coverage (92.8% vs 95.9%, P < .01). After controlling for severity of sepsis, residing in the lowest income quartile compared to the highest quartile was associated with a higher risk of mortality (odds ratio [OR]: 1.06, 95% confidence interval [CI]: 1.03-1.08, P < .01). There was no association seen between the second (OR: 1.02, 95% CI: 0.99-1.05, P = .14) and third (OR: 0.99, 95% CI: 0.97-1.01, P = .40) quartiles compared to the highest., Conclusion: After adjustment for severity of illness, patients with sepsis who live in the lowest median income quartile had a higher risk of mortality compared to residents of the highest income quartile. The association between SES and mortality in sepsis warrants further investigation with more comprehensive measures of SES.

Background: Palliative care is recommended for advanced heart failure (HF) by several major societies, though prior studies indicate that it is underutilized., Aim: To investigate patterns of palliative care referral for patients admitted with HF exacerbations, as well as to examine patient and hospital factors associated with different rates of palliative care referral., Design: Retrospective nationwide cohort analysis utilizing the National Inpatient Sample from 2006 to 2012. Patients referred to palliative care were compared to those who were not., Setting/participants: Patients ≥18 years of age with a primary diagnosis of HF requiring mechanical ventilation (MV) were included. A cohort of non-HF patients with metastatic cancer was created for temporal comparison., Results: Between 2006 and 2012, 74 824 patients underwent MV for HF. A referral to palliative care was made in 2903 (3.9%) patients. The rate of referral for palliative care in HF increased from 0.8% in 2006 to 6.4% in 2012 ( P < .01). In comparison, rate of palliative care referral in patients with cancer increased from 2.9% in 2006 to 11.9% in 2012 ( P < .01). In a multivariate logistic regression model, higher socioeconomic status (SES) was associated with increased access to palliative care ( P < .01). Racial differences were also observed in rates of referral to palliative care., Conclusion: The use of palliative care for patients with advanced HF increased during the study period; however, palliative care remains underutilized in this setting. Patient factors such as race and SES affect access to palliative care.

The impact of chronic exposure to air pollution and outcomes in the acute respiratory distress syndrome (ARDS) is unknown. The Nationwide Inpatient Sample (NIS) from 2011 was utilized for this analysis. The NIS is a national database that captures 20% of all US in-patient hospitalizations from 47 states. Patients with ARDS who underwent mechanical ventilation from the highest 15 ozone pollution cities were compared with the rest of the country. Secondary analyses assessed outcomes of ARDS patients for ozone pollution and particulate matter pollution on a continuous scale by county of residence. A total of 8,023,590 hospital admissions from the 2011 NIS sample were analyzed. There were 93,950 patients who underwent mechanical ventilation for ARDS included in the study. Patients treated in high ozone regions had significantly higher unadjusted hospital mortality (34.9% versus 30.8%, p < 0.01) than patients in cities with control levels of ozone. After controlling for all variables in the model, treatment in a hospital located in a high ozone pollution area was associated with an increased odds of in-hospital mortality (OR 1.11, 95% CI 1.08-1.15, p < 0.01). After adjustment for all variables in the model, for each increase in ozone exposure by 0.01 ppm the OR for death was 1.07 (95% CI 1.06-1.08, p < 0.01). Similarly, for each increase in particulate matter exposure by 10 μg/m 3 , the OR for death was 1.08 (95% CI 1.02-1.16, p < 0.01). Chronic exposure to both ozone and particulate matter pollution is associated with higher rates of mortality in ARDS. These preliminary findings need to be confirmed by further detailed studies., (Copyright © 2017 Elsevier Ltd. All rights reserved.)

Objective: To estimate the rate of acute respiratory distress syndrome (ARDS) in pregnant patients as well as to investigate clinical conditions associated with mortality., Methods: We used the Nationwide Inpatient Sample from 2006 to 2012 to identify a cohort of pregnant patients who underwent mechanical ventilation for ARDS. A multivariate model predicting in-hospital mortality was created., Results: A total of 55,208,382 hospitalizations from the 2006-2012 Nationwide Inpatient Samples were analyzed. There were 2,808 pregnant patients with ARDS who underwent mechanical ventilation included in the cohort. The overall mortality rate for the cohort was 9%. The rate of ARDS requiring mechanical ventilation increased from 36.5 cases (95% confidence interval [CI] 33.1-39.8) per 100,000 live births in 2006 to 59.6 cases (95% CI 57.7-61.4) per 100,000 live births in 2012. Factors associated with a higher risk of death were prolonged mechanical ventilation (adjusted odds ratio [OR] 1.69, 95% CI 1.25-2.28), renal failure requiring hemodialysis (adjusted OR 3.40, 95% CI 2.11-5.47), liver failure (adjusted OR 1.71, 95% CI 1.09-2.68), amniotic fluid embolism (adjusted OR 2.31, 95% CI 1.16-4.59), influenza infection (OR 2.26, 95% CI 1.28-4.00), septic obstetric emboli (adjusted OR 2.15, 95% CI 1.17-3.96), and puerperal infection (adjusted OR 1.86, 95% CI 1.28-2.70). Factors associated with a lower risk of death were: insurance coverage (adjusted OR 0.56, 95% CI 0.37-0.85), tobacco use (adjusted OR 0.53, 95% CI 0.31-0.90), and pneumonia (adjusted OR 0.70, 95% CI 0.50-0.98)., Conclusion: In this nationwide study, the overall mortality rate for pregnant patients mechanically ventilated for ARDS was 9%. The rate of ARDS requiring mechanical ventilation increased from 36.5 cases (95% CI 33.5-41.8) per 100,000 live births in 2006 to 59.6 cases (95% CI 54.3-65.3) per 100,000 live births in 2012.

Objective: There have been suggestions that patients with subarachnoid hemorrhage (SAH) have a better outcome when treated in high-volume centers. Much of the published literature on the subject is limited by an inability to control for severity of SAH., Methods: This is a nationwide retrospective cohort analysis using the Nationwide Inpatient Sample (NIS). The NIS Subarachnoid Severity Scale was used to adjust for severity of SAH in multivariate logistic regression modeling., Results: The records of 47 911 414 hospital admissions from the 2006-2011 NIS samples were examined. There were 11 607 patients who met inclusion criteria for the study. Of these, 7787 (67.0%) were treated at a high-volume center compared with 3820 (32.9%) treated at a low-volume center. Patients treated at high-volume centers compared with low-volume centers were more likely to receive endovascular aneurysm control (58.5% vs 51.2%, P=.04), be transferred from another hospital (35.4% vs 19.7%, P<.01), be treated in a teaching facility (97.3% vs 72.9%, P<.01), and have a longer length of stay (14.9 days [interquartile range 10.3-21.7] vs 13.9 days [interquartile range, 8.9-20.1], P<.01). After adjustment for all baseline covariates, including severity of SAH, treatment in a high-volume center was associated with an odds ratio for death of 0.82 (95% confidence interval, 0.72-0.95; P<.01) and a higher odds of a good functional outcome (odds ratio, 1.16; 95% confidence interval, 1.04-1.28; P<.01)., Conclusion: After adjustment for severity of SAH, treatment in a high-volume center was associated with a lower risk of in-hospital mortality and a higher odds of a good functional outcome., (Copyright © 2016 Elsevier Inc.

Background: To investigate the use of palliative care (PC) in patients with end-stage COPD receiving home oxygen hospitalized for an exacerbation., Methods: A retrospective nationwide cohort analysis was performed, using the Nationwide Inpatient Sample. All patients ≥ 18 years of age with a diagnosis of COPD, receiving home oxygen, and admitted for an exacerbation were included., Results: A total of 55,208,382 hospitalizations from the 2006-2012 Nationwide Inpatient Sample were examined. There were 181,689 patients with COPD, receiving home oxygen, and admitted for an exacerbation; 3,145 patients (1.7%) also had a PC contact. There was a 4.5-fold relative increase in PC referral from 2006 (0.45%) to 2012 (2.56%) (P < .01). Patients receiving PC consultations compared with those who did not were older (75.0 years [SD 10.9] vs 70.6 years [SD 9.7]; P < .01), had longer hospitalizations (4.9 days [interquartile range, 2.6-8.2] vs 3.5 days [interquartile range, 2.1-5.6]), and more likely to die in hospital (32.1% vs 1.5%; P < .01). Race was significantly associated with referral to palliative care, with white patients referred more often than minorities (P < .01). Factors associated with PC referral included age (OR, 1.03; 95% CI, 1.02-1.04; P < .01), metastatic cancer (OR, 2.40; 95% CI, 2.02-2.87; P < .01), nonmetastatic cancer (OR, 2.75; 95% CI, 2.43-3.11; P < .01), invasive mechanical ventilation (OR, 4.89; 95% CI, 4.31-5.55; P < .01), noninvasive mechanical ventilation (OR, 2.84; 95% CI, 2.58-3.12; P < .01), and Do Not Resuscitate status (OR, 7.95; 95% CI, 7.29-8.67; P < .01)., Conclusions: The use of PC increased dramatically during the study period; however, PC contact occurs only in a minority of patients with end-stage COPD admitted with an exacerbation., (Copyright © 2016 American College of Chest Physicians.

Background: Frailty is a multidimensional syndrome characterized by loss of physiologic and cognitive reserve that heightens vulnerability. Frailty has been well described among elderly patients (i.e., 65 years of age or older), but few studies have evaluated frailty in nonelderly patients with critical illness. We aimed to describe the prevalence, correlates, and outcomes associated with frailty among younger critically ill patients., Methods: We conducted a prospective cohort study of 197 consecutive critically ill patients aged 50-64.9 years admitted to intensive care units (ICUs) at six hospitals across Alberta, Canada. Frailty was defined as a score ≥5 on the Clinical Frailty Scale before hospitalization. Multivariable analyses were used to evaluate factors independently associated with frailty before ICU admission and the independent association between frailty and outcome., Results: In the 197 patients in the study, mean (SD) age was 58.5 (4.1) years, 37 % were female, 73 % had three or more comorbid illnesses, and 28 % (n = 55; 95 % CI 22-35) were frail. Factors independently associated with frailty included not being completely independent (adjusted OR [aOR] 4.4, 95 % CI 1.8-11.1), connective tissue disease (aOR 6.0, 95 % CI 2.1-17.0), and hospitalization within the preceding year (aOR 3.3, 95 % CI 1.3-8.1). There were no significant differences between frail and nonfrail patients in reason for admission, Acute Physiology and Chronic Health Evaluation II score, preference for life support, or treatment intensity. Younger frail patients did not have significantly longer (median [interquartile range]) hospital stay (26 [9-68] days vs. 19 [10-43] days; p = 0.4), but they had greater 1-year rehospitalization rates (61 % vs. 40 %; p = 0.02) and higher 1-year mortality (33 % vs. 20 %; adjusted HR 1.8, 95 % CI 1.0-3.3; p = 0.039)., Conclusions: Prehospital frailty is common among younger critically ill patients, and in this study it was associated with higher rates of mortality at 1 year and with rehospitalization. Our data suggest that frailty should be considered in younger adults admitted to the ICU, not just in the elderly. Additional research is needed to further characterize frailty in younger critically ill patients, along with the ideal instruments for identification.

Burn injury introduces unique clinical challenges that make it difficult to extrapolate mechanical ventilator (MV) practices designed for the management of general critical care patients to the burn population. We hypothesize that no consensus exists among North American burn centers with regard to optimal ventilator practices. The purpose of this study is to examine various MV practice patterns in the burn population and to identify potential opportunities for future research. A researcher designed, 24-item survey was sent electronically to 129 burn centers. The χ, Fisher's exact, and Cochran-Mantel-Haenszel tests were used to determine if there were significant differences in practice patterns. We analyzed 46 questionnaires for a 36% response rate. More than 95% of the burn centers reported greater than 100 annual admissions. Pressure support and volume assist control were the most common initial MV modes used with or without inhalation injury. In the setting of Berlin defined mild acute respiratory distress syndrome (ARDS), ARDSNet protocol and optimal positive end-expiratory pressure were the top ventilator choices, along with fluid restriction/diuresis as a nonventilator adjunct. For severe ARDS, airway pressure release ventilation and neuromuscular blockade were the most popular. The most frequently reported time frame for mechanical ventilation before tracheostomy was 2 weeks (25 of 45, 55%); however, all respondents reported in the affirmative that there are certain clinical situations where early tracheostomy is warranted. Wide variations in clinical practice exist among North American burn centers. No single ventilator mode or adjunct prevails in the management of burn patients regardless of pulmonary insult. Movement toward American Burn Association-supported, multicenter studies to determine best practices and guidelines for ventilator management in burn patients is prudent in light of these findings.

Purpose of Review: The purpose of this article is to review recent findings regarding the comorbidity of bipolar disorder with borderline personality disorder (BPD). The conceptualization of the comorbid condition is explored in the context of complexity theory., Recent Findings: Recent studies highlight distinguishing features between the two disorders. The course of illness of the comorbid condition is generally considered to be more debilitating than bipolar disorder alone., Summary: Some of the differentiating features of bipolar disorder and BPD are highlighted. It is also crucial to consider a co-morbid diagnosis as worse outcomes may be anticipated than for bipolar disorder alone. The concept of 'emotional frailty' is introduced and the comorbid bipolar disorder-BPD condition is considered an expression of this syndrome.

Objective: Frailty is a multidimensional syndrome characterized by loss of physiologic reserve that gives rise to vulnerability to poor outcomes. We aimed to examine the association between frailty and long-term health-related quality of life among survivors of critical illness., Design: Prospective multicenter observational cohort study., Setting: ICUs in six hospitals from across Alberta, Canada., Patients: Four hundred twenty-one critically ill patients who were 50 years or older., Interventions: None., Measurements and Main Results: Frailty was operationalized by a score of more than 4 on the Clinical Frailty Scale. Health-related quality of life was measured by the EuroQol Health Questionnaire and Short-Form 12 Physical and Mental Component Scores at 6 and 12 months. Multiple logistic and linear regression with generalized estimating equations was used to explore the association between frailty and health-related quality of life. In total, frailty was diagnosed in 33% (95% CI, 28-38). Frail patients were older, had more comorbidities, and higher illness severity. EuroQol-visual analogue scale scores were lower for frail compared with not frail patients at 6 months (52.2 ± 22.5 vs 64.6 ± 19.4; p < 0.001) and 12 months (54.4 ± 23.1 vs 68.0 ± 17.8; p < 0.001). Frail patients reported greater problems with mobility (71% vs 45%; odds ratio, 3.1 [1.6-6.1]; p = 0.001), self-care (49% vs 15%; odds ratio, 5.8 [2.9-11.7]; p < 0.001), usual activities (80% vs 52%; odds ratio, 3.9 [1.8-8.2]; p < 0.001), pain/discomfort (68% vs 47%; odds ratio, 2.0 [1.1-3.8]; p = 0.03), and anxiety/depression (51% vs 27%; odds ratio, 2.8 [1.5-5.3]; p = 0.001) compared with not frail patients. Frail patients described lower health-related quality of life on both physical component score (34.7 ± 7.8 vs 37.8 ± 6.7; p = 0.012) and mental component score (33.8 ± 7.0 vs 38.6 ± 7.7; p < 0.001) at 12 months., Conclusions: Frail survivors of critical illness experienced greater impairment in health-related quality of life, functional dependence, and disability compared with those not frail. The systematic assessment of frailty may assist in better informing patients and families on the complexities of survivorship and recovery.
