Abstract

Purpose: The purpose of this study was to examine the impact of physical limitations, functional limitations and self-assessed health status on mortality and healthcare utilization among older cancer survivors.

Methods: National Medicare Current Beneficiary Survey (MCBS) cost and use data from 2008 to 2013 were used for analysis. Physical limitations, Activities of Daily Living (ADL), and Instrumental Activities of Daily Living (IADL) were assessed on multiple questions, and self-assessed health was measured on a five-point scale (1-5: Excellent-Poor). Multivariable logistic regression and Poisson regression models were used for hospitalization, re-hospitalization and mortality rates based on three follow up years.

Results: This study included 17,715 cancer patients with a mean age of 75 years and 57% females. Cancer survivors with poor self-assessed health had a higher rate of hospitalizations (adjusted Odds Ratio: aOR: 1.60, 95% Confidence Interval: CI: 1.47-1.72, p < 0.001) relative to non-cancer participants. Compared to participants with no history of cancer, cancer survivors with IADL (aOR: 1.41, 95% CI: 1.25-1.58, p < 0.001) or with poor self-assessed health (aOR: 1.39, 95% CI: 1.21-1.60, p < 0.001) were more likely to have a higher number of hospital readmissions within 30 days of a prior hospitalization. Three-year mortality rate was significantly higher among cancer survivors with poor self-assessed health (Hazard Ratio: 2.81, 95% CI: 2.81-2.82, p < 0.001).

Conclusion: Self-assessed health and physical and functional limitations significantly and independently impact healthcare utilization and mortality among older cancer survivors. Healthcare providers should incorporate formal assessments of both self-assessed health and functional status among older cancer survivors in their clinical practice.

Implication for cancer survivors: Self-reported health status is a valuable and independent predictor of healthcare utilization and mortality among cancer survivors.
