One-year Versus Five-year Hospital Readmission after Ischemic Stroke and TIA [post]

2019 unpublished
The burden of readmission after stroke is substantial, but little knowledge exists on factors associated with long-term readmission after stroke. In a cohort composing patients with ischemic stroke and transient ischemic attack (TIA), we examined and compared factors associated with readmission within 1 year and first readmission during year 2-5. Methods: Patients with ischemic stroke or TIA who were discharged alive between July 2007 and October 2012, were followed for five years by review of

Cox regression was used to identify independent risk factors for readmission within 1 year and first readmission during year 2-5 after discharge. Results: The cohort included 1453 patients, of whom 568 (39.1%) were readmitted within 1 year. Of the 830 patients that were alive and without readmission 1 year after discharge, 439 (52.9%) were readmitted within 5 years. Patients readmitted within 1 year were older, had more severe strokes, poorer functional outcome, and a higher occurrence of complications during index admission than patients readmitted during years 2-5. Cardiovascular comorbidity did not differ between the two groups of readmitted patients. Higher age, poorer functional outcome, coronary artery disease and hypertension were independently associated with first readmission within both 1 year and during year 2-5. Peripheral artery disease was independently associated with readmission within 1 year, and atrial fibrillation was associated with first readmission during year 2-5. Conclusions: More than half of all patients who survived the first year after stroke without any readmissions were readmitted within 5 years. Patients readmitted within 1 year and between years 2-5 shared many risk factors for readmission, but they differed in age, functional outcome and occurrence of complications during the index admission. Background Stroke survivors carries a high risk of new diseases due to functional disability, neurological deficits, and pre-existing cardiovascular risk factors and comorbidity. [1] Readmissions after stroke are frequent, particularly during the first 3 months after stroke when more than half of all patients readmitted within 1 year presents.[2-4] The neurological and functional impairments often improve
