A geriatric re-evaluation clinic is associated with fewer unplanned returns in the Emergency Department: an observational case-control study

Purpose The increasing share of older adults is associated with heavier Emergency Health Services utilization. In this context, a significant problem is the rate of unplanned revisits of geriatric patients after discharge from the Emergency Department (ED). We aimed to evaluate whether the referral to a dedicated Geriatric Revaluation Clinic (GRC) after discharge from the ED is associated with fewer early unplanned returns. Methods We conducted an observational, retrospective, case-control study comparing patients 65 years or older evaluated in a GRC after an ED visit and a control group of same age subjects accessing the ED during the study period and discharged with one of the ICD-9-CM diagnoses used for the cases, for whom defined post-ED assessment was not arranged. The intervention at the GRC consisted of a comprehensive geriatric evaluation. We calculated unadjusted and adjusted OR for unplanned ED revisits within 30 days from ED discharge using two logistic regression models including the variables with statistically significant differences among study groups at univariate analysis. Results During the study period, 121 eligible patients were evaluated at the GRC and were matched to 242 subjects included in the control group. The median age of the study population was 85 years. The adjusted OR for unplanned return after ED discharge and unplanned hospital admission after ED discharge were 0.44 (CI 0.20-0.89) and 0.52 (CI 95% 0.18-1.74), respectively. Conclusions In a population of older patients discharged from the ED, the referral to a GRC is associated with fewer early unplanned revisits.
