Análise da morbidade e mortalidade de crianças e adolescentes internados na Unidade de Terapia Intensiva do Hospital Infantil Nossa Senhora da Glória Vitória-ES em 2006

Abstract

This study was aimed to assess the morbidity, mortality and costs related to children and adolescents admissions to the Pediatric Intensive Care Unit (PICU) of the Hospital Nossa Senhora da Glória/Vitória-ES from November, 2005 to November, 2006, and to evalute the performance of the Pediatric Index of Mortality 2(PIM2) in this PICU. The categorical variables were gathered into the following groups: identification, socioeconomic status, clinical conditions and nosocomial infection. Admissions of two hundred and seventy-six children were studied. The mortality rate was 14,13%, the efficiency of admission was 0,88%, the mean age was 42,22 months, the predominant gender was male 60,1%, the emergency service was responsable for 48,91% of admissions, length of stay was 6,43 5,23 days (mean), and the clinical admissions accounted for 72,46% of all admissions. Significant statistical differences were detected in the following variables: source of admissions (emergency department, surgical and medical wards and other hospitals; p=0,0380), nutricional condition (p=0,0360), mechanic ventilation (p=0,0320), central venous catheter (p=0,0020), clinical admission (p=0,0260), length of stay (p=0,0580), 2 or more antibiotics (p=0,0040). The costs of the internations in the PICU of 87% of patients accounted for 54,76% of global hospital costs related to these admissions. The analysis of the performance of PIM2, as for calibration, showed 2=12,2686 (p=0,1396) in the Hosmer-Lemeshow test, and a standardized mortality ratio of 1,0. The discrimination related to the area under the receiver operating characteristic curve was 0,778, providing a satifactory performance to the score.
