Survival Analysis and Factors Associated With Mortality Among Elderly in a Home Care Program

Abstract

Home care (HC) is directed at older people with high risk of mortality due to clinical, social, and functional vulnerability. The purpose of this study is to analyze the likelihood of survival in a 2-year follow-up of elderly in HC and determine associations between the patient outcome (death/survival) and baseline data. The medical records of 38 elderly in a HC program were analyzed with regard to sociodemographic and clinical data and by the Functional Independence Measure (FIM). After a 2-year period, the records were reanalyzed to determine the patient outcome (death/survival). To determine the mortality rate in the follow-up period, the Kaplan-Meier survival analysis model was used. The Chi square, Fisher exact tests, the Student t and Mann-Whitney tests were used to analyze associations between the baseline variables and program status. The probability of survival was 75.36% and 56.14%, after 1 and 2 years of HC follow-up, respectively. Age, gender, marital status and FIM had no influence on mortality. The elderly who died showed a shorter time of assistance in the HC program, greater number of comorbidities and skin diseases compared to the survivors. Frail and socially vulnerable elderly may benefit from early intervention that focuses on the maintenance of function and the control of clinical complications.
