We evaluated health services utilization among elderly men with stage IV PCa with (M1) and without (M0) distant metastasis during the year following diagnosis. Methods: We evaluated patients aged 66 and older with incident stage IV PCa during 2005–2007 using linked Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Measures included skilled nursing facility (SNF) stay, hospice stay, and hospitalization. Multivariable logistic regression models were estimated to determine the association between M1 PCa and each health service. Poisson regression was used to assess hospital length of stay. Results: The final sample included 3379 patients (20% M0; 80% M1). In the year following diagnosis, M1 patients had greater use of SNF (M0: 8%; M1: 22%), hospice (M0: 5%; M1: 20%), and hospitalization (M0: 43%; M1: 61%). Compared to M0 patients, M1 patients had statistically significantly higher adjusted odds of SNF use (OR = 1.89; 95% CI = 1.38–2.59), hospice use (OR = 3.22; 95% CI = 2.19–4.72), and hospitalization (OR = 1.45; 95% CI = 1.20– 1.75). Among those hospitalized, M1 patients had 24% longer length of stay (p < 0.01). Conclusions: There is 2- to 3-fold greater use of SNF and hospice, and higher hospitalization among M1 compared to M0 patients. Elderly patients with advanced PCa face significant clinical burden within the first year after their diagnosis. Greater understanding of the relationship between clinical disease burden and health services utilization can improve healthcare delivery in this population. © 2014 Elsevier Ltd. All rights reserved.
