Background and purpose: Ischemic stroke is one of the most common neurological diseases that leads to disability in many cases. The aim of this study was to investigate the factors affecting the duration of hospitalization in patients with ischemic stroke undergoing thrombolytic therapy. Materials and methods: This retrospective descriptive-analytical study was performed in consecutive adult patients with ischemic stroke who underwent thrombolytic treatment in Neurology Department of Sari Bu Ali Sina Hospital 2016-2018. Factors associated with duration of hospitalization were investigated. Results: The records of 173 patients (54.9% males) were studied and the mean age of patients was 68.5 ± 12.3 years. During hospitalization, pneumonia, urinary tract infection, and other infections were seen in 19.7%, 9.8%, and 1.2%, respectively. Among the patients, 12.7% experienced hemorrhagic complications. Duration of hospitalization was <7 days in 52.6% and ≥7 days in 47.4% of the patients. Length of hospitalization was significantly associated with hyperlipidemia (P=0.005), stroke severity (P=0.02), large vessel stroke (P<0.001), hemorrhagic complications (P=0.004), and nosocomial infections (P
