[Impact of a short stay unit in a tertiary hospital]

To analyze the health care activity indicators of a short-stay unit (SSU) and compare them with those of other services in a Conventional Hospital.

A descriptive, retrospective study was conducted of the patients admitted to SSU during 2003-2007. Number of admissions, mean stay (MS), mortality and destination were analyzed. Mean stay and number of admissions of the main diagnosis-related groups (DRGs) in the SSU were compared with other services of conventional hospitalization.

A total of 15.3% of the patients who came to the Emergency Service were admitted to the SSU. Mean stay was significantly lower in the SSU than in the rest of the hospital (year 2003, SSU 3.2 days, rest of the hospital 10.2 days; year 2007, SSU 3.3 days, rest of the hospital 8.6 days). The 4 most common DRGs (71.3% of all those admitted to the SSU) were COPD, respiratory infection/bronchitis, simple pneumonia/pleuritis and heart failure/shock. Mean stay for the 4 DRGs in the SSU was significantly lower (p<0.01) than in Internal Medicine, Pneumology and Cardiology (heart failure/shock).

The SSU handles its most prevalent diseases with greater agility compared to other conventional hospitalization services.
