Background: Data on hospital readmission after stroke, which reflects burden of disease, are limited. Our aim was to evaluate readmission and readmission diagnosis within one year after stroke. Methods: We studied administrative claims data of a randomly sampled cohort (n = 200,000) of National Health Insurance beneficiaries in Taiwan. Patients aged >= 18 years and admitted with stroke (International Classification of Diseases, 9th revision, Clinical Modification codes 430 to 438) as principal (first-listed) discharge diagnosis in 2000 were selected for analysis. Each patient's data from January 2000 to December 2001 were obtained. Data analysis was undertaken using descriptive statistics and logistic regression. Results: Among 515 patients identified, 50.1% were ischemic, 20.4% hemorrhagic, 18.3% ill-defined, 10.3% TIA and 1.0% the remainder. Neurologists were admitting physicians for 45.2% of patients. Patients died in hospital (n = 11) and those who were presumed dead during study period (n = 29) or without sufficient follow-up data (n = 7) were excluded. Within one year following discharge from the index admission, approximately half of the patients (232 of 468) were readmitted. The most frequently reported readmission diagnosis was stroke (26.3%), followed by infection (15.1%). Multivariable regression analysis showed that factors significantly associated with increased risk of readmission included age, length of stay of the index admission, medical specialty of admission other than neurology/neurosurgery, and level of hospital, after adjustment for sex, Charlson comorbidity index score, and primary discharge diagnosis (ischemic/hemorrhagic stroke versus others). Conclusions: Stroke patients who were admitted to disciplines other than neurology/neurosurgery seemed to have higher risk of readmission. (C) 2009 Elsevier B. V. All rights reserved.
