Abstract

Objective: to evaluate the clinical outcome of elderly patients admitted to intensive care units who had nosocomial infection, correlating the findings with sociodemographic and clinical variables.

Method: descriptive research, performed with 308 elderly patients. The collection was made from medical records and covers the years 2012 to 2015. Uni-/bivariate analyses were performed.

Results: a statistical association was found between the clinical outcome types and the variables age, length of stay, presence of previous comorbidities, main diagnosis, respiratory and urinary tract infections, use of central venous and indwelling urinary catheters, mechanical ventilation, and tracheostomy. The survival curve showed higher mortality among the elderly from the age of 80 on.

Conclusion: the clinical outcome of the elderly who acquire infection in the intensive care unit is influenced by sociodemographic and clinical variables that increase mortality rates.

Objetivo: avaliar o desfecho clínico de idosos que adquiriram infecção hospitalar hospitalizados em Unidades de Terapia Intensiva, correlacionando os achados com variáveis sociodemográficas e clinicas.

Método: pesquisa descritiva, realizada com 308 pacientes idosos. A coleta deu-se em prontuários e contempla os anos de 2012 a 2015. Realizaram-se análises uni-/bivariadas.

Resultados: registrou-se associação estatística entre os tipos de desfechos clínicos e as variáveis: faixa etária, tempo de internação, presença de comorbidades prévias, diagnóstico principal, infecção do trato respiratório e urinário, uso de cateteres vesical de demora e venoso central, ventilação mecânica e traqueostomia. A curva de sobrevivência evidenciou maior mortalidade entre idosos a partir de 80 anos.

Conclusão: o desfecho clínico de idosos que adquirem infecção na Unidade de Terapia Intensiva é influenciado por variáveis sociodemográficas e clínicas, que incrementam as taxas de mortalidade.
