OBJECTIVES: The objective of this study is to assess descriptively the characteristics and health care resource utilization of patients diagnosed with ovarian cancer. METHODS: A large US administrative retrospective claims database was used to identify patients diagnosed with ovarian cancer and were taking treatment from January 2001 to December 2013 were included in the study. All patients were ≥ 18 years of age and continuously enrolled in the same health plan at least for a year. Descriptive statistics and chi-square tests were performed on the data. RESULTS: There were a total of 2,562 patients that met the study inclusion criteria. There were 1,718 (67.10%) patients <65 years of age (adult) and 844 (32.90%) ≥65 years of age (geriatric). There was a significant difference (p<0.05) between the mean ages of two groups (52.48±9.76 vs 73.08±6.62 years). The mean length of stay of adult patients was lower than (p<0.05) geriatric patients (1.23±1.57 vs 1.45±2.67 days). There were more patients in adult group in the East (23.5% vs 21.0%) and MidWest (30.3% vs 27.6%) regions but no significant difference was found (p>0.05). On average, patients were continuously enrolled in the same health plan for 62.00±37.03 vs 66.64±35.21 months and submitted 567.10±574.49 vs 740.58±629.71 claims with a significant difference (p<0.05) between the two groups. Patients on average were charged by the provider $533.62±2232.26 vs $492.09±2123.24 for their ovarian cancer treatment (p<0.05) during the study period. However, the actual paid amount by the health plan was $225.25±1215.97 vs $136.79±962.99 with a significant difference between the groups (p<0.05). CONCLUSIONS: The majority of the patients were <65 years of age and were paid higher amount by the health plan for the treatment of ovarian cancer.
