Abstract

Objective: To identify predictors of 30-day emergency department (ED) return visits in patients age 65–79 years and age ≥ 80 years. Methods: This was a cohort study of older adults who presented to the ED over a 1-year period. A mixed-effects logistic regression model was used to identify predictors for returning to the ED within 30 days. We stratified the cohort into those aged 65–79 years and aged ≥80 years. Adjusted odds ratios (aORs) with 95% confidence intervals (CI) were reported. This study adhered to the STROBE reporting guidelines. Results: A total of 21,460 ED visits representing 14,528 unique patients were included. The overall return rate was 15% (1998/13,300 visits) for age 65–79 years, and 16% (1306/8160 visits) for age ≥ 80 years. A history of congestive heart failure (CHF), dementia, or prior hospitalization within 2 years were associated with increased odds of returning in both age groups (for age 65–79: CHF aOR 1.36 [CI 1.16–1.59], dementia aOR 1.27 [CI 1.07–1.49], prior hospitalization aOR 1.36 [CI 1.19–1.56]; for age ≥ 80: CHF aOR 1.32 [CI 1.13–1.55], dementia aOR 1.22 [CI 1.04–1.42], and prior hospitalization aOR 1.27 [CI 1.09–1.47]). Being admitted from the ED was associated with decreased odds of returning to the ED within 30 days (aOR 0.72 [CI 0.64–0.80] for age 65–79 years and 0.72 [CI 0.63–0.82] for age ≥ 80). Conclusion: Age alone was not an independent predictor of return visits. Prior hospitalization, dementia and CHF were predictors of 30-day ED return. The identification of predictors of return visits may help to optimize care transition in the ED.
