Improving length of stay on a trauma service

Background Reducing length of stay (LOS) is a major healthcare initiative. While LOS is closely linked to the diagnosis and procedure in elective surgery, many additional factors influence LOS on a trauma service. We hypothesized that more standardized patient management would lead to decreased LOS. Methods Retrospective analysis of Trauma Registry data compared LOS before (PRE) and after (POST) implementation of standardized processes on a trauma service. Patients were subdivided by age (over and under 65 years). Data were compared using unpaired t-test, chi(2) test and analysis of variance tests, where appropriate. Results 1613 PRE and 1590 POST patients were compared. Although age and Injury Severity Score were similar, median LOS decreased by 1 day for the group overall (p<0.0001), and for subgroups over and under the age of 65 years (p<0.0001). Older patients were discharged home 13% more often in POST, compared with 4% more for younger patients. Conclusions Improved standardization of processes on a trauma service reduced LOS in patients of all ages. A prospective study may identify specific factors associated with prolonged LOS, to allow further improvement. Study type Therapeutic/Care management.
