Fatores de risco associados à mortalidade em pacientes vasculopatas internados em hospital terciário

Abstract

Introduction: Patients with vascular disease are repeatedly hospitalized for surgical procedures or medical control of their chronic disease. Objective: Assess predictors factors of mortality in patients during hospitalization. Methods: One hundred and seventeen patients over 18 years admitted for the vascular surgery team in a tertiary hospital during 15 months were assessed for clinical parameters, comorbidities, demographic data, complications during hospitalization and nutritional status. Data were collected through interviews, the questionnaire Subjective Global Assessment (SGA), physical examination of patients, laboratory tests and medical record data. Patient data were recorded from admission until hospital discharge or death. Results: Through univariate analyzes, low serum albumin concentration (P = 0.006), the presence of infectious complications during hospitalization (P = 0.025), presence of heart disease (P = 0.009) and suspected malnutrition or malnutrition detected by SGA (P = 0.026) were factors associated with increased mortality during hospitalization in patients with vascular disease. Both the classification by SGA (OR 6.16, CI 1.09 to 34.74, P = 0.039) and the presence of heart disease (OR 8.51 CI 1.56 to 47.44 P = 0.015) were independent predictors of mortality in multivariate analysis. When the patient was classified as suspected of being malnourished or undernourished the chance of dying during hospitalization increased 6.16 times, while the presence of heart disease increased this chance about 8.51 times. Conclusion: Patients with vascular disease have two independent factors related to increased mortality during hospitalization: previous heart disease presence and condition of malnutrition or suspected malnutrition diagnosed by SGA.
