Impact of Physical and Functional Limitations on Health Care Utilization in Older Cancer Survivors: A Medicare Current Beneficiary Survey

Abstract

Objective: This study examines effects of physical and functional limitations on health care utilization among older cancer survivors, compared with those without cancer and without physical and functional limitations. Method: Medicare Current Beneficiary Survey data from 2008 to 2011 were used. Physical limitations (PL), activities of daily living (ADL), and instrumental activities of daily living (IADL) were measured on a 5-point scale. Propensity score weighting was developed using logistic regressions. Results: Older cancer survivors with physical and functional limitations had higher rate of emergency department visits than those without limitations (PL: 21.8% vs.17%, adjusted odds ratio [aOR]:1.72, 95% confidence interval [CI]: [1.26, 2.35], p < .05; ADL: 25.8% vs.17.4%, aOR: 2.68, 95% CI: [1.86, 3.86], p < .001), and higher cost of hospitalization (IADL: M = US$24,916, SD: 3,877.1). Conclusion: Older cancer survivors with physical and functional limitations had higher health care utilization compared with those without cancer. Addressing complex and unique health care needs in this population will help reduce excess burden on the health care system.
