Emanuel27 challenged studies showing cost savings with hospice care, noting that several methodological issues could invalidate the findings of cost savings for hospice care, such as selection bias, different time frames for assessing costs, fewer cost components evaluated, and generalizability of the studies. Since that 1996 report, the methodology for analyzing cost implications of hospice care has improved—for instance, more medical cost data are available for evaluation compared with the 1990s, when only Medicare Part A was available. Moreover, the author concluded that the use of hospice does not increase costs and does yield better quality of life and increased autonomy at the end of life.27 Of the inherent limitations to the use of retrospective claims data, our study’s main limitation was inability to obtain data on patient and provider preferences regarding hospice election. Another limitation is that the outcome variable examined was limited to survival time, which does not capture effects on quality of life; therefore, quality-adjusted life-years, the preferred measure in cost-effectiveness studies, cannot be estimated. This measure is of particular value for patients at the end of life. Hospice care aims to provide a better quality of life, and indeed, previous studies have shown better quality of life for patients who enroll in hospice care.28-30 However, that the survival time of patients enrolled in hospice was longer than that of patients not electing hospice remains notable. Another consideration is that patients who survived longer might have had more opportunity to use hospice care and for longer durations than those who survived for a shorter period of time. Finally, the years encompassed by our study predate the diffusion of targeted molecular agents such as vemurafenib and ipilimumab, which have recently been shown to improve outcomes for patients with metastatic melanoma. 31 Therefore, it remains to be seen whether continued treatment with newer lifeprolonging treatments such as those mentioned might mitigate the survival improvement associated with 4 or more days of hospice use observed in our study.
Our study showed a significantly longer median survival time for the patients diagnosed with metastatic melanoma who enrolled in 4 or more days of hospice care compared with those who had 0 to 3 days of hospice care, and this improved overall survival was accompanied by lower end-of-life costs. Our evaluation of the survival times and costs of care contributes to the understanding of the potential clinical and economic effects of hospice care on outcomes for patients with metastatic melanoma. Implications of our findings are that communication and education regarding the benefits of hospice care should be a particular priority for patients diagnosed with metastatic melanoma.
