Telephone Follow‐Up for Older Adults Discharged to Home from the Emergency Department: A Pragmatic Randomized Controlled Trial

BACKGROUND/OBJECTIVES: Telephone calls after discharge from the emergency department (ED) are increasingly used to reduce 30-day rates of return or readmission, but their effectiveness is not established. The objective was to determine whether a scripted telephone intervention by registered nurses from a hospital-based call center would decrease 30-day rates of return to the ED or hospital or of death. DESIGN: Randomized, controlled trial from 2013 to 2016. SETTING: Large, academic medical center in the southeast United States. PARTICIPANTS: Individuals aged 65 and older discharged from the ED were enrolled and randomized into intervention and control groups (N = 2,000). INTERVENTION: Intervention included a telephone call from a nurse using a scripted questionnaire to identify obstacles to elements of successful care transitions: medication acquisition, postdischarge instructions, and obtaining physician follow-up. Control subjects received a satisfaction survey only. MEASUREMENTS: Primary outcome was return to the ED, hospitalization, or death within 30 days of discharge from the ED. RESULTS: Rate of return to the ED or hospital or death within 30 days was 15.5% (95% confidence interval (CI) = 13.2-17.8%) in the intervention group and 15.2% (95% CI = 12.9-17.5%) in the control group (P = .86). Death was uncommon (intervention group, 0; control group, 5 (0.51%), 95% CI = 0.06-0.96%); 12.2% of intervention subjects (95% CI = 10.1-14.3%) and 12.5% of control subjects (95% CI = 10.4-14.6%) returned to the ED, and 9% of intervention subjects (95% CI = 7.2-10.8%) and 7.4% of control subjects (95% CI = 5.8-9.0%) were hospitalized within 30 days. CONCLUSION: A scripted telephone call from a trained nurse to an older adult after discharge from the ED did not reduce ED or hospital return rates or death within 30 days.
