Association of Palliative Care With Readmission and Resource Utilization in Patients With Ovarian Cancer: A National Perspective.

Objective: Palliative care (PC) utilization in cancer care has been shown to alleviate symptoms, increase goals of care discussions, and reduce invasive end of life measures. This study examined the association of inpatient PC consultation with readmission and hospitalization costs among patients with ovarian cancer.

Methods: All records for women (≥18 years) hospitalized with a diagnosis of ovarian cancer were tabulated from the 2010-2020 Nationwide Readmissions Database. Multivariable logistic, Poisson, and linear regressions were used to evaluate the association of PC consultation during index hospitalization with length of stay, rates of 30-day non-elective readmission, time to readmission, as well as overall number of readmissions and hospitalization costs.

Results: Of an estimated 285,487 patients included, 25,957 (9.0%) received a PC consultation, with an increase from 5.1 to 11.7% (P < 0.001) across the period. Factors associated with use of PC included: increasing age (AOR 1.03/yr, 95% CI 1.03-1.03, P < 0.001) and Elixhauser comorbidity index (AOR 1.19/point, 95% CI 1.17-1.21). PC was associated with lower risk adjusted rates of 30 day (11.63%, 95% CI 11.0-12.3 vs 20.25%, 95% CI 20.0-20.6) non-elective readmission (P < 0.001). The adjusted incident rate ratio of readmission after PC consultation was 0.41 [0.38-0.43], P < 0.001. Patients receiving PC additionally had less cost associated with their index hospital stay; -$2,407 [-$2,669.86- -$2,144.43], P < 0.001).

Conclusions: Inpatient PC consults appear to be associated with reduced medical readmissions for patients with ovarian cancer, as well as decreased hospital resource use, however disparities exist. Continued increase in access and early PC referral should be considered.
