At the time of hospital discharge, communication between inpatient and outpatient physicians is poor. Multiple studies demonstrate that discharge summaries, a means of improving information exchange between inpatient and outpatient providers, are frequently not available to the outpatient provider at the time of the post discharge visit. We have constructed a web-based solution for generating discharge summaries, SignOut Discharge Summary System (SDSS) which uses the workflow byproduct of SignOut data to pre-populate summaries, a post-discharge preparation module to ensure quality, a discharge edit module to designate accurate discharge summary assignment, and integration with HIM. SDSS had 1130 unique users in a recent period and captured signout information for 75% of hospitalized patients. The system has generated 78740 D/C summaries for 17 specialties since going live July 2005. Overall SDSS is responsible for 69% of all hospital discharge summaries and SDSS discharge summaries on average are available 1.91 days after discharge.
