Introducing case management to a general medicine ward team of a teaching hospital

Abstract

Purpose: To introduce case management to a general medicine ward team of a teaching hospital to improve patient care and ensure comprehensive longitudinal care.

Method: The Department of Veterans Affairs Medical Center is one of four hospitals used by University of Oklahoma School of Medicine residents. There are five medicine teams, each comprising a second- or third-year resident, one or two interns, two medical students, and a faculty physician. The case-management program was initiated in November 1994. No attempt was made to limit the residents assigned to the case-managed team (i.e., many residents who worked with the case-managed team subsequently rotated through the other teams). Patients were assigned to the teams by rotation, and no attempt was made to adjust for the severity of illness among admissions. The teams were separated as follows: pre-case-management teams (all five teams prior to the case-management program), non-case-management teams (the four teams without case managers after the program's initiation), and the case-management team. The study periods were January-July 1994 (pre-case management) and January-July 1995 (after case management).

Results: The numbers of patients treated by the three groups were 1,305, 1,139, and 289, respectively. The median length of stay for pre-case-management patients was 5 days (interquartile range, 3-9 days); for non-case-management patients, 5 days (range, 3-8 days); and for case-management patients, 5 days (range, 3-7 days). The cumulative distribution of lengths of stay for case-management patients was significantly different from those of the other study groups by the Kolmogorov-Smirnov test (p = .02). More case-management patients were discharged by day 7. Rates of readmission were not significantly different between the teams.

Conclusion: In this study a case-management program was effectively implemented in a teaching hospital, resulting in reduced lengths of stay for patients. As academic health centers become more concerned with efficiency and cost, case management should be seriously considered as a way to deal with such issues.
