The transfer of care at hospital discharge is complex and requires the transmission of large amounts of data between inpatient physicians (hospitalists) and outpatient physicians (PCPs), including information about pending tests. Frequently, laboratory and radiology tests are not finalized until after a patient is discharged, and when the responsibility for these pending results is not clearly defined, they can be missed. Our project aims to define the problem of these post-discharge results and to study the implementation of an EMR-based system (Hospitalist Results Manager, HRM) for tracking these results on the hospitalist services at Brigham and Women’s Hospital (BWH) and Massachusetts General Hospital (MGH). The project consists of two phases: a cross-sectional study before intervention to define the epidemiology of post-discharge results, and a randomized trial of HRM to determine its effect on physician awareness of these results.
