Trends and Disparities in Inpatient Palliative Care Use in Metastatic Renal Cell Carcinoma Patients Receiving Critical Care Therapy.

Purpose: Temporal trends in and predictors of inpatient palliative care use in patients with metastatic renal cell carcinoma (mRCC) undergoing critical care therapy are unknown.

Methods: Relying on the National Inpatient Sample (2008-2019), we identified mRCC patients undergoing critical care therapy, namely invasive mechanical ventilation, percutaneous endoscopic gastrostomy tube insertion, dialysis for acute kidney failure, total parenteral nutrition, or tracheostomy. Estimated annual percentage changes (EAPC) analyses and multivariable logistic regression models addressed inpatient palliative care use.

Results: Of 3802 mRCC patients undergoing critical care therapy, 817 (21.5%) received inpatient palliative care. Overall, inpatient palliative care use increased from 4.9% to 31.5% between 2008 and 2019 (EAPC +9.2%). In subgroup analyses, the highest increase in inpatient palliative care use was observed in the Midwest (EAPC: +11.9%), in the South (EAPC +10.4%), and in teaching hospitals (EAPC +9.0%; all P ≤ .004). In logistic regression models, teaching hospital status (odds ratio [OR] 1.41) and contemporary year interval (OR 2.12; all P < .001) independently predicted higher inpatient palliative care rates. Conversely, hospital admission in the Northeast (OR 0.53) or in the South (OR 0.79; all P ≤ .03) was associated with lower inpatient palliative care rates than in the West.

Conclusion: In mRCC patients, inpatient palliative care rates have improved over time, with the highest increase in hospitals in the Midwest and in the South. Moreover, admission to teaching hospitals or in the West is associated with higher inpatient palliative care rates. In consequence, regional disparities, as well as differences according to teaching hospital status represent targets to achieve comprehensive inpatient palliative care coverage in mRCC patients receiving critical care therapy.
