Trends, Sociodemographic and Hospital-Level Factors Associated With Palliative Care Utilization Among Multiple Myeloma Patients Using the National Inpatient Sample (2016-2018)

Background Several factors are reported to be associated with palliative care utilization among patients with various cancers, but literature is lacking on multiple myeloma (MM) specific factors. MM patients have a high symptom burden and early involvement of palliative could increase their quality of life. We examined factors associated with palliative care utilization among MM patients and explored prevalence trends in palliative care utilization among patients with MM. Methods Cross-sectional analyses were conducted using the National Inpatient Sample data collected between 2016 and 2018. Descriptive analyses were used to explore prevalence trends in palliative care utilization over time. Multivariable logistic regression models were used to examine sociodemographic and hospital-level factors associated with palliative care utilization in MM patients. Results Overall prevalence of palliative care utilization in our population was 7.7% with a trend of increasing use of palliative care from 7.3% in 2016 to 8.2% in 2018. MM patients aged 70 years and above had 1.30 times higher odds (95% CI: 1.20-1.42) of receiving palliative care relative to those younger than 70 years. Compared to non-Hispanic whites, non-Hispanic blacks (Adjusted odds ratio (AOR): 0.86; 95% CI: 0.79-0.94) were less likely to utilize palliative care. Patients on Medicaid (AOR: 1.27; 95% CI: 1.08-1.49), private insurance (AOR: 1.27; 95% CI: 1.16-1.39) and other insurance types (AOR: 2.10; 95% CI: 1.79-2.47) had significantly higher odds of receiving palliative care when compared to those on Medicare. Other factors identified were hospital region, location, patient disposition, admission type, length of stay, and number of comorbidities. Conclusion Our findings highlight the urgent need for education of hospital physicians on the need for early palliative care involvement in the care of hospitalized MM patients. Messaging interventions such as the delivery of pop-up messages in electronic medical records to serve as reminders for physicians can be explored as a potential way to increase palliative care consultations for patients who need them.
