Background: Palliative Care (PC) has been shown to improve quality of life in lung cancer patients, and ASCO recommends it as an adjunct to standard oncologic care. Data regarding the use of PC in other cancers and in disadvantaged populations is scant. We studied the patterns of use of PC in patients with metastatic breast cancer (MBC) at a safety net hospital. Methods: Electronic health records (EHR) of 234 patients who were diagnosed with MBC from 2010 to 2016 at Parkland Health and Hospital System (PHHS) were reviewed, and data on demographics, diagnostics, treatments, and palliative care elements were collected. Results: 105 of 234 (44.8%) patients with MBC were referred to PC, either as outpatients, inpatients, or both. The average time from the first visit with medical oncology to placement of an outpatient referral to PC was 390 days. Of the 79 patients with outpatient referrals to palliative care, we have hormone receptor status on 50. 12 of these patients had triple negative breast cancer; 30 had hormone receptor positive breast cancer. 77 (32% of all patients) patients had formal documentation of advanced directives (AD) in the EHR. Of these, 69 (89.6%) had seen PC. 133 patients have died, and 37 (27.8% of expired patients) died at the Parkland Hospital. Among the 96 patients who did not die in the hospital, 73 (76%) patients had some discussion of hospice prior to death. Conclusions: Less than half of patients with MBC at PHHS were referred to PC, and among those who are, referrals are placed late in the disease course, on average, more than one year after the first medical oncology visit. Lack of a sustained relationship with PC results in truncated goals of care discussions. As a result, most patients do not have formal documentation of AD in the EHR. Furthermore, they do not benefit from discussions with PC that could guide the management of their malignancy while they still have therapeutic options. Instead, patients discuss hospice with their providers toward the end of life, only when they are no longer candidates for cancer directed therapies. Although the use of PC resources at PHHS does not meet clinical guidelines, it is consistent with data from other studies showing inadequate use of PC resources among patients with advanced cancer.
