Parada cardiorrespiratória intra-hospitalar precoce em um hospital do Nordeste do Brasil: perfil clínico-epidemiológico

Abstract

Introduction: In-hospital cardiac arrest (IHCA) within the first 24 hours of admission is a critical event, associated with high morbidity and mortality. Analyzing its clinical and epidemiological profile is essential to optimize early recognition protocols and rapid response strategies. Objective: To describe the clinical and epidemiological profile of adult patients who experienced IHCA within 24 hours of hospitalization at the University Hospital of Lagarto (HUL) between January 2020 and December 2023, and to investigate possible associations between demographic, clinical, arrest rhythm, and location variables. Methods: A quantitative, retrospective, and cross-sectional study was conducted based on medical records and death certificates. Variables were recorded using REDCap® and analyzed with GraphPad Prism® version 10. Fisher’s exact test and the Mann-Whitney test were applied, adopting a significance level of 5% (p<0.05). Results: The analysis revealed a high prevalence of multimorbidity, particularly systemic arterial hypertension and diabetes mellitus, along with a predominance of non-shockable rhythms. Conclusion: These findings highlight the importance of rigorous clinical monitoring during the first hours of hospitalization and rapid interventions to improve prevention and management of IHCA.
