Ischemic stroke hospital stay and discharge destination.
OBJECTIVE
Stroke hospitalizations are among the most expensive, with a mean length of stay (LOS) higher than other hospitalizations. This retrospective study assesses factors influencing ischemic stroke LOS taking into consideration the discharge destination of patients.


METHODS
Linked hospital separation records between July 1995 and December 1999 were extracted to determine the first admission for ischemic stroke in Western Australia. Multiple hospitalization records for the same patient were screened to obtain the total duration of hospitalization. Demographic characteristics, hospital type, and medical history of patients were also retrieved. In the presence of censoring and without prior assumption on the time-to-discharge distribution, the Cox's proportional hazards model was used to assess the factors affecting LOS.


RESULTS
During the study period, 6469 patients with a first-ever admission for ischemic stroke were identified, with average LOS being 28 days (95% CI, 26-30 days). Hospital stays were significantly longer for females and patients directly admitted to hospitals maintaining a specialist stroke unit, whereas patients residing in rural areas had shorter stays.


CONCLUSIONS
The impact of stroke severity and placement in nursing homes after discharge need to be understood to manage LOS and the cost of acute care. Accurate diagnosis upon initial presentation would benefit both the efficiency of hospitals and the outcomes of rural ischemic stroke patients.
