Abstract
Purpose
It is generally known that health-related quality of life (HRQOL) predicts cause-specific mortality. Few studies have explored whether generic self-reported HRQOL, sociodemographic factors and illness variables are independently associated with mortality among cognitively intact nursing home (NH) residents with and without cancer. We hypothesized that sociodemographic factors and illness variables would be associated with mortality and that HRQOL, measured using the SF-36 Health Survey, would predict mortality among NH residents with and without cancer.
Methods
We followed a cohort of 227 cognitively intact (Clinical Dementia Rating scale score ≤0.5) older residents (60 with cancer and 167 without) from 30 NH from 2004–2005 to 2010. We collected data by face-to-face interview. We obtained sociodemographic variables and medical diagnoses from the records.
Results
Survival did not differ between residents with and without cancer (P = 0.31). Twenty percent of the residents with cancer and 13% without cancer were still alive. After adjustment for sociodemographic and illness variables, increasing age (P < 0.001), higher education (P = 0.009), comorbidity (P = 0.04) and the subdimension physical functioning (P = 0.009) predicted mortality. Bodily pain was only marginally associated with mortality (P = 0.08).
Conclusions
Independent of cancer, HRQOL and comorbidity predicted mortality among NH residents without cognitive impairment.
