The article in the Journal of the American Geriatrics Society discusses the challenges of managing head trauma in older adults, who make up the majority of head injury cases in emergency departments. The study focuses on deriving a prediction model to identify which older adults with head injuries should undergo brain imaging in the emergency department. The Florida Geriatric Head Trauma CT Clinical Decision Rule is introduced as a tool to help avoid unnecessary brain imaging in older adults who have sustained head impacts, marking a significant advancement in geriatric medicine. The study emphasizes the importance of external validation and generalizability of the decision rule to diverse clinical populations. [Extracted from the article]

Background The relative contributions of long-term care (LTC) resident frailty and home-level characteristics on COVID-19 mortality has not been well studied. We examined the association between resident frailty and home-level characteristics with 30-day COVID-19 mortality before and after the availability of SARS-CoV-2 vaccination in LTC. Methods We conducted a population-based retrospective cohort study of LTC residents with confirmed SARS-CoV-2 infection in Ontario, Canada. We used multi-level multivariable logistic regression to examine associations between 30-day COVID-19 mortality, the Hubbard Frailty Index (FI), and resident and home-level characteristics. We compared explanatory models before and after vaccine availability. Results There were 11,179 and 3,655 COVID-19 cases in the pre- and post-vaccine period, respectively. The 30-day COVID-19 mortality was 25.9 and 20.0% during the same periods. The median odds ratios for 30-day COVID-19 mortality between LTC homes were 1.50 (95% credible interval [CrI]: 1.41–1.65) and 1.62 (95% CrI: 1.46–1.96), respectively. In the pre-vaccine period, 30-day COVID-19 mortality was higher for males and those of greater age. For every 0.1 increase in the Hubbard FI, the odds of death were 1.49 (95% CI: 1.42–1.56) times higher. The association between frailty and mortality remained consistent in the post-vaccine period, but sex and age were partly attenuated. Despite the substantial home-level variation, no home-level characteristic examined was significantly associated with 30-day COVID-19 mortality during either period. Interpretation Frailty is consistently associated with COVID-19 mortality before and after the availability of SARS-CoV-2 vaccination. Home-level characteristics previously attributed to COVID-19 outcomes do not explain significant home-to-home variation in COVID-19 mortality. [ABSTRACT FROM AUTHOR]

Introduction: While overdoses comprise the majority of opioid research, the comprehensive impact of the opioid crisis on emergency departments (EDs) and paramedic services has not been reported. We examined temporal changes in population-adjusted incidence rates of ED visits and paramedic transports due to opioid-related conditions. Materials and methods: We conducted a population-based cohort study of all ED visits in the National Ambulatory Care Reporting System from January 1, 2009 to December 31, 2019 in Ontario, Canada. We included all patients with a primary diagnosis naming opioids as the underlying cause for the visit, without any other drugs or substances. We clustered geographic regions using Local Health Integration Network boundaries. Descriptive statistics, incidence rate ratios (IRR) and 95% confidence intervals (CIs) were calculated to analyze population-adjusted temporal changes. Results: Overall, 86,403 ED visits were included in our study. Incidence of opioid-related ED visits increased by 165% in the study timeframe, with paramedic transported patients increasing by 429%. Per 100,000 residents, annual ED visits increased from 40.4 to 97.2, and paramedic transported patients from 12.1 to 67.9. The proportion of opioid-related ED visits transported by paramedics increased from 35.0% to 69.9%. The medical acuity of opioid-related ED visits increased throughout the years (IRR 6.8. 95% CI 5.9–7.7), though the proportion of discharges remained constant (~75%). The largest increases in ED visits and paramedic transports were concentrated to urbanized regions. Discussion: Opioid-related ED visits and paramedic transports increased substantially between 2009 and 2019. The proportion of ED visits transported by paramedics doubled. Our findings could provide valuable support to health stakeholders in implementing timely strategies aimed at safely reducing opioid-related ED visits. The increased use of paramedics followed by high rates of ED discharge calls for exploration of alternative care models within paramedic systems, such as direct transport to specialized substance abuse centres.

Background Little is known about the prognostic differences between older emergency department (ED) patients who present with different formal support requirements in the community. We set out to describe and compare the patient profiles and patterns of health service use among three older ED cohorts: home care clients, nursing home residents and those receiving no formal support. Methods We conducted a secondary analysis of the Canadian cohort from the interRAI multinational ED study. Data were collected using interRAI ED contact assessment on patients 75 years of age and older (n = 2,274), in eight ED sites across Canada. A series of descriptive statistics were reported. Adjusted associations were determined using logistic regression. Results Older adults receiving no formal support services were most stable. However, they were most likely to be hospitalized. Older home care clients were most likely to report depressive symptoms and distressed caregivers. They also had the greatest odds of frequent ED visitation post-discharge (OR=1.9; 95% CI=1.39-2.59). Older adults transferred from a nursing home were the frailest but had the lowest odds of hospital admission (OR=0.14; 95% CI=0.09-0.23). Conclusion We demonstrated the importance of inquiring about community-based formal support services and provide data to support decision-making in the ED. [ABSTRACT FROM AUTHOR]

A decline in physical function is commonly observed after patients transition to their homes following hospital admission; this is especially true for patients requiring mechanical ventilation in an intensive care unit (ICU).This meta-analysis examines characteristics and effects of home-based or outpatient+home-based interventions used to improve physical function post-discharge in patients who received mechanical ventilation in an ICU.PRISMA guidelines were utilized. The literature search was conducted with the assistance of a medical librarian. Study inclusion criteria were post-ICU adult patients receiving mechanical ventilation who then had home-based or outpatient+home-based care to improve physical function after discharge. Effect size (Hedges’ g) was calculated with random effects models.Our search yielded 11 studies that met the inclusion criteria. The majority were randomized controlled trials, with 1 quasi-experimental study. All studies included physical therapists, and 2 included nurses. The 11 studies reported results for 39 physical function measurements. The overall pooled intervention effect across the 4 studies that utilized the 6-minute walk test was 0.32 (95% confidence intervals [CI]: 0.05 to 0.58), for the 3 studies that utilized the Timed Up and Go test it was 1.38 (95% CI: −0.09 to 2.84), and for the 8 studies that used the SF-36 Physical Function subscale, it was 0.31 (95% CI: 0.09 to 0.52).This review’s findings show that patients may improve their physical function after participating in specific intervention programs that are home-based alone or outpatient+home-based care. However, the effect sizes are small, so it may be useful to explore how to maximize the gains in physical function. [ABSTRACT FROM AUTHOR]
