Abstract

Introduction: Stroke is among the leading causes of morbidity and mortality in the population Objective: To describe the length of hospital stay of stroke patients and verify related factors. Methodology: Retrospective cohort study; between 2017 and 2020 with age ≥18 years. Sociodemographic, health, clinical, and care-related variables were used, as well as complications and outcome. Descriptive statistics were performed, the incidence of the dependent variable (mean 10-day hospital stay) with 95% confidence interval (95% CI) was calculated and the difference according to the predictor variables (complications, time of symptom onset, comorbidities and Glasgow) was verified by employing the chi-square test. Results: Sample composed of n of 708, majority of the sample is male (51.5%), age ≤59 years (30.1%), white (92.7%) and coming from a municipality disparate from the Specialized Center (56.3%). The most common form was ischemic (88.8%) and the mean hospital stay was 10.48 (±9.85) days, being 10.49 (±10.06) for CVAi and 10.94 (±8.49) for CVAh. Of the total, 67% (95% CI 64-71) were hospitalized for up to 10 days. The presence of some type of complication, infectious or cardiovascular complications and low Glasgow, are the main predictors of longer hospital stay. The lethality rate was 13.7%. Conclusions: The average length of hospital stay is among the lowest in the literature and the main predictors of longer hospital stay are similar to those described by other authors, as well as the lethality, which is close to the state average.
