Disparities in hospitalized cancer patients receiving palliative care consultation.

Abstract

7 Background: Racial and ethnic disparities in healthcare have been well documented among minority groups with respect to access to care, receipt of care, and quality of care. As a result, minority populations are diagnosed with late stage cancer and have inferior outcomes likely leading to increased suffering. Little is known, however, about disparities in access to and outcomes of patients receiving specialty palliative care (PC). Methods: We used data from the Palliative Care for Cancer Patients (PC4C) study, a multisite observational study of the effect of inpatient PC on patient health outcomes and health services use among advanced cancer patients. We limited our sample to patients that received PC from established, interdisciplinary consult teams. We used univariate analyses and multiple regression analyses to compare differences in outcomes among minority (black and Hispanic) and non-minority patients receiving PC. Results: 583 (19%) patients received a PC consult. Of those, 166 (28%) were minorities and 418 (72%) non-minorities. Mean days to a palliative care consult was 4.4 vs. 3.2 in non-minorities and minorities, respectively (p=0.65). At baseline, minority patients reported a higher burden of symptoms as measured by the condensed memorial symptom assessment scale (CMSAS). Similarly, they were less likely to have talked about their wishes with their doctor (p=0.04); less likely to have completed a living will (p<0.001), or have a proxy (p<0.001); had no difference in pain but were less likely to be taking pain medications (p<0.001) or report relief from pain medicines (p=0.05). After PC consult all CMSAS symptoms improved for minority patients (except worry; p=0.03). Additionally, after PC consult there were no longer any significant differences among minorities with respect to discussing their wishes (p=0.27), DNR completion (p=0.72), proxy assignment (p=0.22) and taking pain medications (p=0.22) when compared to non-minorities. Conclusions: PC is associated with improvements in symptom control and discussions of care goals among minority patients who have worse baseline health assessments. Future efforts need to focus on increasing the availability and use of specialty PC for this at-risk population.
