Hospital challenges faced by frail patients with ovarian cancer and the adverse outcomes: A nationwide study.

5572 Background: Ovarian cancer is a leading cause of gynecological cancer-related deaths and one of the most common causes of cancer-related fatalities among women. Frailty has been identified as a predictor of unfavorable outcomes for cancer patients, but there is limited research on its impact on individuals with ovarian cancer. We examined the effects of Frailty in hospitalized ovarian cancer patients and the associated outcomes. Methods: National Inpatient Sample (NIS) 2020 was used to identify the patients with a primary diagnosis of ovarian cancer (local/regional and advanced metastatic) and was stratified into patients with and without Frailty. The primary outcome was mortality, and secondary outcomes included length of stay, the total cost of hospitalization, and other in-hospital adverse outcomes. Multivariate logistic regression analysis was used to calculate the outcomes after adjusting for confounding variables. Results: A total of 19790 patients were hospitalized with a primary diagnosis of Ovarian cancer, among which 3215 (16. 24%) patients had the concurrent diagnosis of Frailty. The mean age of patients with and without Frailty was 65. 76 (+/-13. 10) and 60 (+/-14. 45), p<0. 001, respectively. After adjusting for confounding variables, Frailty was associated with an increased risk of mortality in patients with ovarian cancer (OR=3. 01 (1. 83-4. 95) ; p<0. 001). Patients with Frailty were also at risk of increased length of stay (+3. 80 Days (3. 09-4. 50; p<0. 001) and total cost of hospitalization (+ 34662 (22973-46351) ; p<0. 001). Frail patients also had an increased likelihood of Acute respiratory failure (OR=1. 72 (1. 22-2. 42) ; p=0. 002), Acute kidney injury (OR=2. 40 (1. 88-3. 05) ; p<0. 001), Sepsis (OR=4. 97 (3. 19-7. 75) ; p<0. 001), ICU admission (OR=2. 23 (1. 44-3. 45) ; p<0. 001), Pneumonia (OR=2. 63 (1. 69-4. 10) ; p<0. 001), total parenteral nutrition (OR=14. 20 (7. 80-25. 83) ; p<0. 001) and Intubation (OR=2. 11 (1. 21-3. 69) ; p=0. 008). However, there was no difference in the risk of noninvasive mechanical ventilation (OR=2. 07 (0. 95-4. 52) ; p=0. 48) or enteral feeding (OR=32. 73 (0. 63-1696) ; p=0. 08). Conclusions: Frailty in ovarian cancer patients is considered an independent predictor of mortality. It is also associated with increased healthcare resource utilization and adverse in-hospital outcomes. Table: see text
