Abstract 360: A Simplified Post-Discharge Telephone Intervention To Reduce Hospital Readmission for Patients with Cardiovascular Disease.
Background: Readmission rates are high for patients with cardiovascular disease, particularly heart failure (HF) and acute coronary syndrome (ACS). Telephone calls by clinical staff have had mixed effects. We aim to evaluate the degree of implementation and the effect of a quality improvement initiative using a simplified post-discharge phone call by administrative assistants. Methods: Clinical data were retrospectively reviewed at a single urban public hospital. From January through October 2012 all patient discharged home from inpatient cardiology services (intervention group, n=1034 discharges) were identified. Within 7 days, administrative assistants contacted patients via telephone and queried regarding (1) medication compliance, (2) awareness of follow-up appointments and (3) if clinician contact is requested. Outcome events were defined as readmissions (for any cause) within 30 days to the same hospital and are reported as patients experiencing readmission, and total readmissions. A comparison group of all patients discharged home from inpatient cardiology services from January through October 2010 (n=746) were selected as controls (no phone calls). Categorical data were compared in a univariate fashion using the Chi Square test. Statistical significance is defined as p<.05. Results: Of the 1034 discharge events in the intervention group, 620 (60.0%) had phone calls attempted. Of those, 419 (67.6%) were directly contacted. Patients were statistically different with respect to language, ethnicity and insurance status. Of the patients called, 48 (7.7%) reported medication abnormalities, 13 (2.1%) did not understand their follow-up and 38 (6.1%) had a question for a clinician. The rates of patients experiencing events was not statistically different (132 [17.7%] vs. 156 [15.1%], OR 0.85, p=.14). Total readmissions were significantly reduced (157[21.0%] vs. 179 [17.3%], OR 0.82, p=.047). Pre-specified subgroups of ACS and HF patients showed a trend towards decreased re-admissions but were not statistically significant. Conclusion: A simplified post-discharge telephone call strategy is associated with a trend towards reduced hospital readmissions for cardiology patients. Further refinements are needed to improve program implementation.
