Abstract

Introduction Data are limited on whether the causes of Emergency Department (ED) attendance and clinical outcomes vary by frailty status. Methods Using data from the Nationwide Emergency Department Sample, all ED attendances from 2016 to 2018 were stratified by the cause of attendance and Hospital Frailty Risk Score (HFRS) category. Logistic regression was used to determine adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) of ED and overall mortality. Results A total of 155,497,048 ED attendances were included, of which 125,809,960 (80.9%) had a low HFRS (<5), 27,205,257 (17.5%) had an intermediate HFRS (5–15) and 2,481,831 (1.6%) had a high HFRS (>15). The most common cause of ED attendance in the high HFRS group was infectious diseases (43.0%), followed by cardiovascular diseases (CVD) (24.0%) and respiratory diseases (10.2%). Musculoskeletal diseases were the most common cause of admission for the low HFRS group (21.2%), followed by respiratory diseases (20.6%), and gastrointestinal diseases (18.5%). On adjusted analysis, high HFRS patients had increased overall mortality (combined ED and in-hospital) across most attendance causes, compared to their low HFRS counterparts (p < 0.001). High HFRS patients with infectious diseases (aOR 23.88 95% CI 23.42–24.34), CVD (aOR 2.58 95% CI 2.55–2.61) and respiratory diseases (aOR 36.90 95% CI 36.18–37.62) had an increased risk of overall mortality, compared to their low-risk counterparts (p < 0.001). Conclusions A significant proportion of patients attending the ED are frail, with the cause of attendance varying by frailty status. Frailty is associated with increased overall mortality across most attendance causes.
