Trends, sociodemographic and hospital-level factors associated with inpatient palliative care utilization among malignant melanoma patients: A 5-year National Inpatient Sample (NIS) study.

Abstract

e21526 Background: Palliative care improves the quality of life in cancer patients; however, there is no literature on specific factors that predict its use in patients with malignant melanoma. We explored the prevalence trends, and predictors of palliative care utilization among hospitalized patients with malignant melanoma. Methods: Retrospective analyses were conducted using the National Inpatient Sample (NIS) data collected between 2016 and 2020. Descriptive analyses and multivariable regression models were used to investigate the prevalence trends, and sociodemographic and hospital-level factors associated with palliative care utilization in hospitalized malignant melanoma patients. Results: Of the 9,760 hospitalizations with a diagnosis of malignant melanoma over the study duration, 14% utilized palliative care during their hospital stay. Overall, 9.2% of malignant melanoma patients used palliative care and were discharged alive. There was a stable trend of palliative care use over the 5-year period (14%). Compared to patients on Medicare, those on Medicaid were twice (adjusted odds ratio (AOR): 2.12; 95% confidence interval (CI): 1.26–3.64) more likely to utilize palliative care. Relative to other regions in the US, patients hospitalized in the West were 40% less likely to receive the service of the palliative team (AOR: 0.61; 95% CI: 0.38-0.96). Those admitted to teaching hospitals (AOR: 0.55; 95% CI: 0.40-0.77) had lower odds of having palliative care consultations when compared to non-teaching hospitals. Patients admitted to urban hospitals had 50% (AOR: 0.51; 95% CI: 0.27–0.98) lesser odds of getting palliative care when compared to their counterparts in rural hospitals. Individuals who were either discharged to a facility/with home health (AOR: 8.81; 95% CI: 5.88–13.23) or died during hospitalization (AOR: 128.42; 95% CI: 72.10–228.77) had higher odds of utilizing palliative care when compared to those with a routine discharge. Conclusions: The prevalence of palliative care utilization was low, and factors associated with utilization in our population were identified. Our findings emphasize the necessity to improve awareness among medical oncologists and primary inpatient teams on the importance of involving the palliative care service early in the management of hospitalized patients with malignant melanoma.
