Abstract
e24083 Background: Palliative care is a resource that is utilized for patients with serious illnesses to focus on symptom management, quality of life, and goals of care for patients and their families. It can be initiated at any point in illness course with benefit beginning as early as the time of diagnosis. This study's objective is to evaluate trends in inpatient palliative care utilization and associated factors in patients with ovarian cancer. Methods: We performed a retrospective cohort study using the National Inpatient Sample (NIS) from 2010-2020. Patients with ovarian, fallopian tube, and primary peritoneal cancer and palliative care (PC) utilization were identified using ICD-10 codes. Chi square and t tests were used to evaluate differences between patients who received PC versus patients who did not. Multivariate and multinomial logistic regression was utilized to determine factors associated with PC use. Results: A total of 479,169 patients with a diagnosis of ovarian cancer were included, of which 58,970 (12.3%) utilized inpatient PC. Between 2010 and 2020, there was a significant upwards trend in PC usage in patients hospitalized with a diagnosis of ovarian cancer from 6.9% to 18.1%. Median age of patients using PC was 67 compared to 65 among those not using PC (p < 0.001). PC utilization was more prevalent among patients with a diagnosis of depression (8.7% v 6.4%; p < 0.001), Black race (12.4% v 10.3%; p < 0.001), in urban environments (94.0% v 92.2%; p < 0.001), and those at hospitals designated as teaching status (72.4% v 66.8%; p < 0.001). In a multivariate regression analysis, the odds of palliative care utilization were 1.59times higher (p < 0.001) for patients with moderate loss of function compared to patients with minor loss of function. Patients with hospital stays 0-3 days were more likely to utilize palliative care compared to 4-7 days (p < 0.001) Multinomial logistic regression for disposition among patients using palliative care to additional care versus routine care was 1.59 times higher in patients with 8+ days hospital stay compared to 4-7 days. For those with shorter stays of 1-3 days versus 4-7 days patients were 1.65 times more likely to die versus routine care. Conclusions: The use of inpatient PC for patients with ovarian cancer increased over time. Palliative care utilization was associated with older age, Black race, depression, and treatment in urban environments or in teaching hospitals. The utilization of inpatient palliative care was higher in patients with more extreme losses of function. These patients were more likely to have shorter lengths of stay due to a higher disposition of death over routine care. Given these findings, patients receiving palliative care may be sicker and closer to the end of life than those who do not. Although there have been higher rates of inpatient palliative care over time, there is still room for earlier implementation.
