Background:
In Germany up-to-date data within community settings about factors influencing length of stay in acute hospitals are lacking. We, therefore, identified predictors for length of stay in acute hospital after ischemic stroke in a pooled analysis of large German stroke registers.
Methods:
Ischemic stroke patients admitted to hospitals cooperating within the German Stroke Registers Study Group (ADSR) between January 1, 2000 and December 31, 2000 were analysed. The influence of patients' demographic and clinical characteristics as well as the characteristics of the treating hospitals on length of stay were analysed by multivariate linear regression.
Results:
Overall, 13 440 patients after ischemic stroke were included in the analyses. Their mean age was 70 years, 53 % were men. Median length of stay in acute hospitals was 12 days. In multivariate analyses younger age, an increasing number of co-morbidities, and an increasing number of neurological deficits were identified as predictors of prolonged stay in hospital. Patients were more likely to stay longer in an acute hospital if they were to be discharged to a rehabilitation unit or to a nursing home. Length of stay was independently decreased for patients treated in hospitals providing acute stroke unit services and for hospitals treating more than 250 stroke patients per year.
Conclusion:
In addition to patients' demographic and clinical characteristics, length of stay in hospital was influenced by the hospitals' characteristics. Especially the volume of treated patients and the organisation of services within the hospital may play the key role.
