Stroke epidemiology and in-hospital mortality in a Mexico City hospital: a prospective two-years study

Abstract

Objective: To describe patient characteristics, case fatality rate, and assess predictors of in-hospital acute ischemic (IS) or hemorrhagic stroke (HS) mortality. Method: Adult patients with confirmed stroke were recruited from January 1st, 2018 to December 31st, 2019. Data collect included: demographic and laboratory characteristics, risk factors, and clinical outcome. A binary logistic regression model with relative risk and 95% confidence interval was performed. Results: A total of 172 patients were recruited; IS was present in 78.5% of patients. The mean of age was 75.27 ± 11.44 years in IS group and 71.62 ± 11.72 years in HS group. Hypertension was present in > 70% of patients in both groups; the in-hospital case fatality rate was 15.5% for IS and 21.5% for HS. Severe NIHSS score (> 13) was significantly associated with in-hospital mortality in both stroke types. Conclusions: Hypertension was the most common risk factor in patients with stroke. The in-hospital case fatality rate was lower to previously reported in Mexico. Nevertheless, it remains high compared to reported in developed countries. NIHSS scale was the strongest predictor of mortality. There is a need to develop more effective stroke management services in Mexico.
