Healthcare utilization among cancer patients prior to hospice.
135 Background: The integration of palliative medicine in oncologic care has become increasingly recognized and supported. We have previously reported improved health system and quality of care outcomes for solid tumor patients admitted to our novel, fully-integrated palliative care (PC) and medical oncology inpatient service at Duke University Medical Center (DUMC). In this study, we explored healthcare utilization in patients specifically discharged to hospice pre- and post-PC integration. Methods: We conducted a retrospective cohort study of hospitalized patients on the solid tumor unit at DUMC who were discharged to hospice care between September 1, 2009-June 30, 2010 (pre-PC integration) and September 1, 2011-June 30, 2012 (post-PC integration). Cohorts were compared on the following outcome variables occurring within 30 days prior to discharge to hospice: number of hospitalizations, ICU days, ED visits, invasive procedures, subspecialty consultations, radiologic studies, medical oncology clinic visits, and use of chemotherapy or radiation. Wilcoxon rank-sum and Chi square tests were used for statistical analyses. Results: A total of 296 patients were included (133 pre-PC integration; 163 post-PC integration) in the analyses. Patient characteristics were well matched between cohorts. The overall mean age was 63 years (range 25-96), 62% were Caucasian, 51% were male, and 98% of patients had recurrent or metastatic disease. Of particular note, there were no significant differences noted between cohorts with regards to the resource utilization outcome variables assessed. Conclusions: Understanding healthcare utilization in this patient population is of great interest to clinical providers and policymakers alike. While we have previously demonstrated the benefit of integrating palliative care and medical oncology for reducing hospital readmissions and length of stay, this study shows no significant impact of an integrated approach on the utilization of healthcare resources measured within the 30 days prior to discharge to hospice. This may reflect the aggressive approach to management of symptoms for end-of-life patients, which often involves invasive procedures, use of imaging, and other resources to meet their needs.
