Do rural cancer patients receive lower quality cancer care? Assessing the impact of rurality on oncology practice performance measures

166 Background: Rural residents are diagnosed at later stages of cancer compared to urban residents, have poorer survival, and face distinct barriers to receiving quality cancer care. ASCO has developed policy initiatives to address rural cancer care; however, little is known about quality of cancer care among patients residing in rural areas. This study examined the impact of rurality on performance metrics, controlling for socioeconomic status and insurance type. Methods: We linked Washington state cancer registry records from 2015-2017 with claims records for two large commercial insurers, Medicare, and Medicaid. Using claims from this database, we generated eight nationally recognized quality measures. Rurality was measured by the Rural-Urban Commuting Area Codes (RUCAs) categorized into 4 levels (Metro, Metro with commute, Micropolitan, Small Town/Rural). Process and outcome measures were adjusted for age, sex, race, comorbidity score, stage, cancer type, marital status, the Area Deprivation Index, and treatment factors where appropriate. Results were stratified by payer type. Results: The table below lists the effect of a patient’s rurality on the quality metric where significant (p
