Manrriquez E, Mandelbaum A, Aguayo E, et al. - Researchers sought the factors linked with high-cost inpatient admissions for ovarian cancer. They defined admissions with high-cost as those sustaining ≥ 90th percentile of hospitalization costs each year, while the rest were assumed low-cost. Using the 2010–2017 National Inpatient Sample, they identified 58,454 patients for inclusion in this study. Among these, 5,827 patient admissions (9.98%) were categorized as high-cost. For this high-cost group, they recorded median hospitalization cost of $55,447 vs $16,464 for the low-cost group. This indicates that expanses afforded by the top 10% of operative hospitalizations for ovarian cancer patients are three times more than the remainder. Among patients with high-cost admissions, open or extended procedures were more frequent and non-elective admissions were more likely. Over the study period, decreasing inpatient costs were recorded, this may be due to fewer open and extended procedures with subsequently shorter lengths of stay. Clinical factors were shown to outweigh socioeconomic factors as cost drivers among patients largely covered by Medicare.
