Length of stay LOS is one of the most important quantitative indexes that measures health service utilization within a hospital. Many studies have examined the association of three major stroke categories with LOS. Our aim is to investigate the differences of LOS among ischemic stroke subtypes, results from which are helpful to healthcare providers and government agencies to improve health care delivery efficiency.

Methodology-Principal Findings

Using the Beijing Municipal Health Bureau’s hospitalization summary reports, we performed a retrospective study among first-ever in-hospital patients with ischemic stroke ICD-10 I63 in three general teaching hospitals in Beijing, China, from 2006 to 2010 with generalized linear model. In our study, 5,559 patients female, 36.0%; age, 64.4±12.9 years were included. The estimated mean LOS of ischemic stroke was 17.4±1.8 days. After adjusting for confounders, LOS of lacunar infarction 14.7 days; p<0.001 and LOS of small cerebral infarction 17.0 days; p = 0.393 were shorter than that of single cerebral infarction 17.9 days, p<0.001. LOS of multi-infarct 19.0 days; p = 0.028, brainstem infarction 19.3 days; p = 0.045, basal ganglia infarction 18.5 days; p = 0.452 and other subtypes of ischemic stroke 18.9 days; p = 0.327 were longer than that of single cerebral infarction.


LOS of ischemic stroke patient differes across single cerebral infarction, lacunar infarction, multi-infarct and brainstem infarction patients. The ascending order of LOS was lacunar infarction, small cerebral infarction, single cerebral infarction, basal ganglia infarction, other subtypes of ischemic stroke, multi-infarct and brainstem infarction.
