Abstract

Objective: To describe the clinical-epidemiological characteristics of patients hospitalized in an intensive care unit (ICU) in Brazil over a 12-month period. Materials and Methods: Cross-sectional, prospective study, nested within a cohort, carried out in the adult intensive care unit of a university hospital. Data was collected using data from the electronic medical records via the Health Care Management System of the Unified Health System to monitor admissions and outcomes of patients hospitalized during the defined period. Data were obtained on variables such as sex, race/color, age group, municipality of residence, place of origin, need for surgery, use of vasoactive drugs, presence of acute infections, presence of certain comorbidities, lifestyle habits, systemic impairment and clinical evolution. The data were analyzed by means of simple descriptive statistics using the R software. Results: Of the 252 patients, the majority were male (59.13%) and their ages ranged from 18 to 94 years (?=58.6), with 134 of
them over 60 years of age. The majority of patients were white (62.70%), and there was a predominance of admissions from communities in the region near the city of Maringá (52.38%), 96 patients denied engaging in any practice harmful to their health. The reason for admission or the human body system most affected by admission to the ICU was the pulmonary system (22.22%). Conclusions: The highest prevalence of admissions to the intensive care unit was due to male individuals, aged between 41 and 59 years, coming from emergency care, requiring surgery, having comorbidities, being smokers and being discharged home.
