Abstract 304: Characteristics of Acute Coronary Syndrome Patients Referred to the Bridge Transitional Care Clinic By Time to Readmission

Introduction: Prompt follow-up post-discharge is recommended by many readmission reduction initiatives. Identifying predictors of early readmission may inform discharge planning. We compared characteristics of acute coronary syndrome (ACS) patients (pts) based on time to readmission to determine factors associated with early readmission.

Methods: Pts referred to the BRIDGE transitional care clinic following index admission for ACS from 2008-2017 were eligible. Demographics and inpatient clinical characteristics were compared between pts readmitted early (0-7 days post-discharge) versus late (8-30 days post-discharge). Multivariable logistic regression models were created to identify independent predictors of early readmission.

Results: Of 1220 ACS pts, 198 were readmitted within 30 days; 70 (35.4%) were readmitted early, and 10.0% of these were readmitted for ACS. Early readmissions were more likely to be female, have an ED visit prior to readmission, and have an index ICU admission. Female sex [OR: 2.26, 95% CI: 1.23, 4.16] and ICU admission [OR: 2.20, 95% CI: 1.14, 4.24] were both independent predictors of early readmission.

Conclusion: Female sex and ICU admission during index were associated with roughly twice the odds of early readmission. Non-white pts were also more often readmitted early (p=0.05), suggesting potential care disparities in this population. Future studies to identify pts at increased risk of early readmission and efforts to reduce disparities are warranted.
