  • Objectives: To determine predictors of repeat health service use in older veterans treated and released from the emergency department (ED).

    Design: Retrospective cohort study.

    Setting: Veterans Affairs Medical Center (VAMC) EDs.

    Participants: Nationally representative sample of veterans aged 65 and older treated and released from one of 102 VAMC EDs between October 1, 2007, and June 30, 2008.

    Measurements: Logistic regression models were used to examine the association between independent variables and primary outcomes (30-day repeat ED visits and hospital admissions).

    Results: In 31,206 older veterans, ED diagnoses were commonly related to chronic conditions (22.5%), injuries and acute musculoskeletal conditions (19%), and infections (13.5%). Within 30 days, 22% of older veterans had returned to the ED (n = 4,779) or been hospitalized (n = 2,005). In adjusted models, factors associated with greater odds of repeat ED visits than injury were homelessness (odds ratio (OR) = 1.6, 95% confidence interval (CI) = 1.3�2.1), previous ED visits (OR = 1.7, 95% CI = 1.6�1.8), previous hospitalization (OR = 1.3, 95% CI = 1.2�1.4), and index ED visit related to infection (1.2, 95% CI = 1.1�1.3). Odds of subsequent hospital admission were higher in veterans with previous hospitalization (OR = 2.5, 95% CI = 2.2�2.8), who were homeless (OR = 1.5, 95% CI = 1.1�2.0), who had aid and attendance benefits (OR = 1.5, 95% CI = 1.2�1.8), who were unmarried (OR = 1.2, 95% CI = 1.1�1.3), and who had an ED visit related to a chronic condition (OR = 1.4, 95% CI = 1.2�1.6) than in those with injury.

    Conclusion: A substantial proportion of older veterans treated and released from a VAMC ED returned to the ED or were hospitalized within 30 days. Intervening with high-risk older veterans after an ED visit may reduce unscheduled healthcare use.
