Abstract

Background
Published literature provides an incomplete description of the palliative care needs of the hematologic malignancies (HM) population. We sought to compare characteristics of hospice patients with HM vs. those with solid tumors.

Methods
Patient data (2008-2012) were extracted from the electronic records of 10 hospices in the CHOICE network (Coalition of Hospices Organized to Investigate Comparative Effectiveness). We identified the subset with HM using ICD-9 codes, comparing them to the subset with all other neoplasias using bivariate analyses.

Results
Of the 48,147 cancer patients, 3,518 (7.3%) had a hematologic malignancy, with rates not changing substantially over the 5-year study period (Table 1). HM patients were somewhat older and more often male, with a slight, but significant tendency to be more often Caucasian (see Table 1). At time of admission, HM patients had worse physical functioning by Palliative Performance Scale (PPS) scores (32% vs. 24% were below 40; p<0.001) and were more likely to be admitted to an inpatient hospice or nursing home setting vs. home (OR 1.34, CI 1.16-1.56, and OR 1.54, CI 1.39-1.72; p<0.001). HM patients were more likely to have a hospice length of stay (LOS) of 1 day (OR 1.66, CI 1.49-1.86; p<0.001), or of less than 7 days (OR 1.68, CI 1.56-1.81; p<0.001). Patients with leukemia were more likely to have a LOS of 1 day compared to those with lymphoma (OR 1.31, CI 1.1-1.56; p=0.002), and were more likely to die during the study period (HR 1.23, CI 1.13-1.34; p<0.001). Patients with multiple myeloma or myelodysplastic syndrome were more likely than other HM patients to be taking an opioid at admission (OR 1.37, CI 1.12-1.67; p=0.002, and OR 1.29, CI 1.01-1.64; p =0.042). Patients with myelodysplasia were also more likely to have an advance directive or durable power of attorney in place at admission compared to other HM patients (OR 1.36, CI 1.07-1.72; p=0.012).

Conclusions
Patients with hematologic malignancies who are referred to hospice appear to be more seriously ill at time of admission, with worse physical functioning scores by PPS and shorter length of stay compared to other cancer patients. Targeted efforts to better understand the palliative care needs of the hematologic malignancies population are warranted.
