Economic burden and treatment patterns of gynecologic cancers in the United States: evidence from the Medical Expenditure Panel Survey 2007–2014 / 부인종양

ABSTRACT

Objective@#This study estimated nationally representative medical expenditures of gynecologic cancers, described treatment patterns and assessed key risk factors associated with the economic burden in the United States. @*Methods@#A retrospective repeated measures design was used to estimate the effect of gynecologic cancers on medical expenditures and utilization among women. Data were extracted from the Medical Expenditure Panel Survey (weighted sample of 609,787 US adults) from 2007 to 2014. Using the behavioral model of health services utilization, characteristics of cancer patients were examined and compared among uterine, cervical, and ovarian cancer patients. Multivariable linear regression models were conducted on medical expenditure with a prior logarithmic transformation. @*Results@#The estimated annual medical expenditure attributed to gynecologic cancers was $3.8 billion, with an average cost of $6,293 per patient. The highest annual cost per person was ovarian cancer ($13,566), followed by uterine cancer ($6,852), and cervical cancer ($2,312). The major components of medical costs were hospital inpatient stays (53%, $2.03 billion), followed by office-based visits (15%, $559 million), and outpatient visits (13%, $487 million). Two key prescription expenditures were antineoplastic hormones (10.3%) and analgesics (9.2%). High expenditures were significantly associated with being a married woman (p<0.001), having private health insurance (p<0.001), being from a low- and middleincome family (p<0.001), or living in the Midwest or the South (p<0.001). @*Conclusion@#The key risk factors and components were well described for the economic burden of gynecologic cancers. With a growing population of cancer patients, efforts to reduce the burden of gynecologic cancers are warranted.
