Background Strategies to reduce readmissions have focused on transitions of care processes. Prior data suggest that early physician follow-up after hospitalization for heart failure may reduce readmissions. 1 Whether this strategy is effective for acute myocardial infarction (AMI) patients is unknown. 1 Hernandez, AF et al. JAMA. 2010;303:1716-1722
Objectives To characterize hospital variation in early physician follow-up after discharge for non-ST- segment elevation myocardial infarction (NSTEMI) To examine the relationship between rates of early physician follow-up and risk of readmission
Methods: Data sources and study population Clinical data from CRUSADE registry linked with longitudinal Medicare claims data from 2003-2006 NSTEMI pts ≥65 years surviving to hospital discharge (n= 42,568) Patients discharged home (n= 31,789) Transfer to acute care facility (n= 4,474) Transfer to skilled nursing facility/hospice (n= 6,305) Analysis population: n= 27,852 patients at 228 sites Non-index admissions (n= 949) Hospitals w/o PCI & CABG (n= 3,849) Hospitals with < 25 pts remaining (n= 927)
Methods: Definitions and outcome Early physician follow-up MD visit within 7 days of discharge Primary outcome: 30-day all-cause readmission
Methods: Statistical analyses Logistic regression with hospital as random effect to examine hospital-level early follow-up and 30-day readmission Adjustment models: 1) Patient demographic and clinical characteristics 2) #1 + hospital features (bed size, region, academic status) 3) #2 + treatment features (discharge medications, revascularization)

Study limitations Observational study - residual confounding No data regarding non-physician post- discharge medical contacts Limited to follow-up w/in 7 days and readmission w/in 30 days Hospital-level measure insensitive Low overall rates of early follow-up
Conclusions 1 in 5 older NSTEMI patient readmitted within 30 days of discharge Most patients not seen in follow-up by a physician within 7 days of discharge Overall hospital rate of early physician follow-up low but variable No association between early physician follow- up and 30-day readmission demonstrated
Future directions Prospective assessment of early physician follow-up and readmission Examination of other strategies to reduce readmission after AMI Effectiveness of early follow-up as part of bundled strategy rather than isolated intervention
