Institutional, therapeutic, and individual factors associated with 30-day mortality after COVID-19 diagnosis in Canadian long-term care facilities.

ABSTRACT:

Background

Canadian long-term care facility (LTCF) residents experienced higher death rates compared to other countries during the first wave of the COVID-19 pandemic. This cohort study analyzes the individual, therapeutic, and institutional factors associated with death in LTCFs.

Methods

Institutional data for 17 LTCFs in Montreal, Canada were obtained from local administrative registries. Individual data for 1197 residents infected by SARS-CoV-2 between February 23 and July 11, 2020 were obtained through chart reviews. A multivariable modified Poisson regression model, which accounted for LTCF clustering, was used to identify resident and facility covariates associated with 30-day mortality after COVID-19 diagnosis.

Results

Severe shortage of licensed practical nurses (RR 2.60 95% CI 1.20-5.61) and medium-sized facilities compared to smaller-sized facilities (RR 2.73 95% CI 1.23-6.07) were associated with 30-day mortality. Later COVID-19 diagnosis (RR 0.98 95% CI 0.97-0.99 per additional day) was associated with survival. Individual risk factors for death included age (RR 1.33 95% CI 1.23-1.45 per additional 10 years), male sex (RR 1.46 95% CI 1.24-1.71), functional impairment (RR 1.08 95% CI 1.04-1.12 per unit increase of SMAF), as well as a diagnosis of congestive heart failure (RR 1.31 95% CI 1.04-1.66) and neurocognitive disorder (RR 1.31 95% CI 1.01-1.70). Among severe cases, anticoagulation was associated with survival (RR 0.70 95% CI 0.51-0.96).

Conclusions

This study identified practical nurse shortages and facility size as institutional risk factors for COVID-19 death. Anticoagulation was associated with survival among severe cases.

Project description:ImportanceLong-term care (LTC) residents may be susceptible to social isolation if living in facilities located in neighborhoods lacking social connection.ObjectiveTo characterize the social isolation of residents living in LTC facilities in the US.Design, setting, and participantsThis cross-sectional study included 730 524 LTC residents from 14 224 LTC facilities in 8652 zip code tabulation areas (ZCTAs) in the US in 2011. A nationwide LTC database with ZCTA data was linked to population-level geographic data from the US Census Bureau. Statistical analysis was performed from January 2019 to December 2020.ExposuresThe primary variable of interest was the social isolation of LTC neighborhoods defined as the percentage of households in the ZCTA with individuals aged 65 years or older who lived alone and categorized into quartiles of social isolation.Main outcomes and measuresMaps were generated to illustrate geographic variation of LTC facilities at the ZCTA level by the quartile of socially isolated neighborhoods. Generalized estimating equations were used to estimate the adjusted likelihood that LTC facilities were located in areas of highest social isolation. We also used multilevel logistic regression models to assess the association between the social isolation of neighborhoods of LTC facilities and 30-day all-cause mortality after LTC admission. Subgroup analyses were conducted by race and ethnicity.ResultsAmong 33 120 ZCTAs in the US, 8652 (26.1%) had at least 1 LTC facility. Among the 730 524 LTC residents included in the study's 14 224 LTC facilities, 458 136 (62.71%) were female, 610 802 (83.61%) were non-Hispanic White, and 419 654 (57.45%) were aged 80 years or older. Location of LTC facilities was associated with increasing levels of social isolation (quartile 1 = 9.72% [n = 840]; quartile 2 = 18.60% [n = 1607]; quartile 3 = 32.23% [n = 2784]; quartile 4 = 39.45% [n = 3408]; P < .001). In multivariate models, LTC facilities were 8 times more likely to be located in ZCTAs with the highest percentages of older adults residing in single-occupancy households (odds ratio [OR], 8.46; 95% CI, 7.44-9.65; P < .001), compared with ZCTAs with the lowest percentages. This association held across ZCTAs with a majority population of African American and Hispanic individuals, although it was strongest in ZCTAs with a majority population of White individuals. LTC residents entering facilities in neighborhoods with the highest levels of social isolation among older adults had a 17% higher risk of 30-day mortality (OR, 1.17; 95% CI, 1.10-1.25; P < .001) compared with those in neighborhoods with the lowest levels of social isolation among older adults.Conclusions and relevanceThis study found that LTC facilities were often located in socially isolated neighborhoods, suggesting the need for special attention and strategies to keep LTC residents connected to their family and friends for optimal health.

Project description:AimsSpontaneous coronary artery dissection (SCAD) was underdiagnosed and poorly understood for decades. It is increasingly recognized as an important cause of myocardial infarction (MI) in women. We aimed to assess the natural history of SCAD, which has not been adequately explored.Methods and resultsWe performed a multicentre, prospective, observational study of patients with non-atherosclerotic SCAD presenting acutely from 22 centres in North America. Institutional ethics approval and patient consents were obtained. We recorded baseline demographics, in-hospital characteristics, precipitating/predisposing conditions, angiographic features (assessed by core laboratory), in-hospital major adverse events (MAE), and 30-day major adverse cardiovascular events (MACE). We prospectively enrolled 750 SCAD patients from June 2014 to June 2018. Mean age was 51.8 ± 10.2 years, 88.5% were women (55.0% postmenopausal), 87.7% were Caucasian, and 33.9% had no cardiac risk factors. Emotional stress was reported in 50.3%, and physical stress in 28.9% (9.8% lifting >50 pounds). Predisposing conditions included fibromuscular dysplasia 31.1% (45.2% had no/incomplete screening), systemic inflammatory diseases 4.7%, peripartum 4.5%, and connective tissue disorders 3.6%. Most were treated conservatively (84.3%), but 14.1% underwent percutaneous coronary intervention and 0.7% coronary artery bypass surgery. In-hospital composite MAE was 8.8%; peripartum SCAD patients had higher in-hospital MAE (20.6% vs. 8.2%, P = 0.023). Overall 30-day MACE was 8.8%. Peripartum SCAD and connective tissue disease were independent predictors of 30-day MACE.ConclusionSpontaneous coronary artery dissection predominantly affects women and presents with MI. Despite majority of patients being treated conservatively, survival was good. However, significant cardiovascular complications occurred within 30 days. Long-term follow-up and further investigations on management are warranted.

Project description:ObjectivesThe risk of short-term mortality after an emergency department (ED) visit for syncope is poorly understood, resulting in prognostic uncertainty and frequent hospital admission. The authors determined patterns and risk factors for short-term mortality after a diagnosis of syncope or near syncope to aid in medical decision-making.MethodsA retrospective cohort study was performed of adult members of Kaiser Permanente Southern California seen at 11 EDs from 2002 to 2006 with a primary discharge diagnosis of syncope or near syncope (International Classification of Diseases, Ninth Revision [ICD-9] 780.2). The outcome was 30-day mortality. Proportional hazards time-to-event regression models were used to identify risk factors.ResultsThere were 22,189 participants with 23,951 ED visits, resulting in 307 deaths by 30 days. A relatively lower risk of death was reached within 2 weeks for ages 18 to 59 years, but not until 3 months or more for ages 60 and older. Preexisting comorbidities associated with increased mortality included heart failure (hazard ratio [HR] = 14.3 in ages 18 to 59 years, HR = 3.09 in ages 60 to 79 years, HR = 2.34 in ages 80 years plus; all p < 0.001), diabetes (HR = 1.49, p = 0.002), seizure (HR = 1.65, p = 0.016), and dementia (HR = 1.41, p = 0.034). If the index visit followed one or more visits for syncope in the previous 30 days, it was associated with increased mortality (HR = 1.86, p = 0.024). Absolute risk of death at 30 days was under 0.2% in those under 60 years without heart failure and more than 2.5% across all ages in those with heart failure.ConclusionsThe low risk of death after an ED visit for syncope or near syncope in patients younger than 60 years old without heart failure may be helpful when deciding who to admit for inpatient evaluation. The presence of one or more comorbidities that predict death and a prior visit for syncope should be considered in clinical decisions and risk stratification tools for patients with syncope. Close clinical follow-up seems advisable in patients 60 years and older due to a prolonged risk of death.

Project description:PurposeThe 30-day mortality rate after hip fracture surgery has been considered as an indirect indicator of the quality of care. The aim of this work is to analyse preoperative and postoperative factors potentially related to early 30-day mortality in patients over 65 undergoing hip fracture surgery.MethodsProspective cohort study including all consecutive primary hip fracture patients over 65 admitted to Trauma and Orthopaedics department from January 1, 2018 to December 31, 2019. Bed-ridden, non- surgically treated patients, and high energy trauma or tumoral aetiology fractures were excluded. A total of 943 patients were eligible (attrition rate: 2.1%). Follow-up included 30-days after discharge. We noted the 30-day mortality after hip fracture surgery, analysing 130 potentially related variables including biodemographic, fracture-related, preoperative, and postoperative clinical factors. Qualitative variables were assessed by χ2, and quantitative variables by non-parametric tests. Odds ratio determined by binary logistic regression. We selected preventable candidate variables for multivariate risk assessment by logistic regression.ResultsA total of 923 patients were enrolled (mean age 86.22±6.8, 72.9% women). The 30-day mortality rate was 6.0%. We noted significant increased mortality on men (OR = 2.381[1.371-4.136], p = 0.002), ageing patients (ORyear = 1.073[1.025-1.122], p = 0.002), and longer time to surgery (ORday = 1.183[1.039-1146], p<0.001), on other 20 preoperative clinical variables, like lymphopenia (lymphocyte count <103/μl, OR = 1.842[1.063-3.191], p = 0.029), hypoalbuminemia (≤3.5g/dl, OR = 2.474[1.316-4.643], p = 0.005), and oral anticoagulant intake (OR = 2.499[1.415-4.415], p = 0.002), and on 25 postoperative clinical variables, like arrhythmia (OR = 13.937[6.263-31.017], p<0.001), respiratory insufficiency (OR = 7.002[3.947-12.419], p<0.001), hyperkalaemia (OR = 10.378[3.909-27.555], p<0.001), nutritional supply requirement (OR = 3.576[1.894-6.752], p = 0.021), or early arthroplasty dislocation (OR = 6.557[1.206-35.640], p = 0.029). We developed a predictive model for early mortality after hip fracture surgery based on postoperative factors with 96.0% sensitivity and 60.7% specificity (AUC = 0.863).ConclusionWe revealed that not only preoperative, but also postoperative factors have a great impact after hip fracture surgery. The influence of post-operative factors on 30-day mortality has a logical basis, albeit so far they have not been identified or quantified before. Our results provide an advantageous picture of the 30-day mortality after hip fracture surgery.
