Differences in youngest-old, middle-old, and oldest-old patients who visit the emergency department

TLDR

Clinical characteristics of elderly patients in the ED vary with age as people age. The study examined age‑related differences among elderly patients (65+) in the ED by categorizing them into youngest‑old (65–74), middle‑old (75–84), and oldest‑old (≥85) groups over a two‑year period. Data were collected on demographics, visit reasons, transfers, treatments, admission types, departments, and length of stay for 11,236 patients aged 65 and older out of 64,287 ED visits. Older age groups had higher female proportions, more medical causes, higher admission rates, increased internal medicine and orthopedic surgery admissions, longer ED stays, lower discharge home rates, and higher mortality compared to younger‑old patients.

Abstract

As aging progresses, clinical characteristics of elderly patients in the emergency department (ED) vary by age. We aimed to study differences among elderly patients in the ED by age group.For 2 years, patients aged 65 and older were enrolled in the study and classified into three groups: youngest-old, ages 65 to 74 years; middle-old, 75 to 84 years; and oldest-old, ≥85 years. Participants' sex, reason for ED visit, transfer from another hospital, results of treatment, type of admission, admission department and length of stay were recorded.During the study period, a total 64,287 patients visited the ED; 11,236 (17.5%) were aged 65 and older, of whom 14.4% were 85 and older. With increased age, the female ratio (51.5% vs. 54.9% vs. 69.1%, P<0.001), medical causes (79.5% vs. 81.3% vs. 81.7%, P=0.045), and admission rate (35.3% vs. 42.8% vs. 48.5%, P<0.001) increased. Admissions to internal medicine (57.5% vs. 59.3% vs. 64.7%, P<0.001) and orthopedic surgery (8.5% vs. 11.6% vs. 13.8%, P< 0.001) also increased. The ratio of admission to intensive care unit showed no statistical significance (P=0.545). Patients over age 85 years had longer stays in the ED (330.9 vs. 378.9 vs. 407.2 minutes, P<0.001), were discharged home less (84.4% vs. 78.9% vs. 71.5%, P<0.001), and died more frequently (6.3% vs. 10.4% vs. 13.0%, P<0.001).With increased age, the proportion of female patients and medical causes increased. Rates of admission and death increased with age and older patients had longer ED and hospital stays.
