title: Effect of discharge summary availability during post-discharge visits on hospital readmission.
abstract: OBJECTIVE
  To determine if the delivery of hospital discharge summaries to follow-up physicians decreases the risk of hospital readmission.
  
  
  METHODS
  Eight hundred eighty-eight patients discharged from a single hospital following treatment for an acute medical illness.
  
  
  METHODS
  Teaching hospital in a universal health-care system.
  
  
  METHODS
  We determined the date that each patient's discharge summary was printed and the physicians to whom it was sent. Summary receipt was confirmed by survey and phoning each physician's office. Each patient's hospital chart was reviewed to determine their acute and chronic medical conditions as well as their course in hospital. Using population-based administrative databases, all post-hospitalization visits were identified. For each of these visits, we determined whether the summary was available.
  
  
  METHODS
  Time to nonelective hospital readmission during 3 months following discharge.
  
  
  RESULTS
  The discharge summary was available for only 568 of 4,639 outpatient visits (12.2%). Overall, 240 (27.0%) of patients were urgently readmitted to hospital. After adjusting for significant patient and hospitalization factors, we found a trend toward a decreased risk of readmission for patients who were seen in follow-up by a physician who had received a summary (relative risk 0.74, 95% confidence interval 0.50 to 1.11).
  
  
  CONCLUSIONS
  The risk of rehospitalization may decrease when patients are assessed following discharge by physicians who have received the discharge summary. Further research is required to determine if better continuity of patient information improves patient outcomes.
