Acute Care for the Elderly (ACE) units have successfully decreased length of stay, hospital costs, and readmission rates. Furthermore, patients return home with increased functional capacity and improved satisfaction with their hospital stay. The ACE unit concept was geared toward patients returning to independent living, but the average hospitalized geriatric patient is increasingly more frail, vulnerable, and dependent. The purpose of this study is 2-fold: (1) to determine if the ACE unit continues to offer the same benefit to the frail, often bedbound elderly, and (2) to determine if such a unit is able to maintain standard hospital quality indicators. A total of 1096 cases discharged from the Memorial-Hermann ACE unit between July 2008 and June 2010 were compared to a sample of 383 patients with similar illness severity who were discharged between July 2007 and June 2008. Metrics measured include: average length of stay (ALOS), case mix index (CMI), case mix adjusted average length of stay (CMI adj ALOS), average direct costs per case, and readmission rate. Patient satisfaction was measured using Hospital Consumer Assessment of Healthcare Providers and Systems and Press-Ganey surveys; quality and safety data were provided by Memorial-Hermann's Quality and Safety Department. The ACE unit resulted in a statistically significant decrease in ALOS and CMI adj LOS with a simultaneous increase in Health Care Financing Administration CMI, indicating that the unit was serving a sicker, more frail population. The readmission rate was 11.95%. The decrease in length of stay, readmission rate, and direct cost translates into a decrease in cost per case. Furthermore, the ACE unit successfully met hospital quality indicators. |
