Effectiveness of Using Personal Health Records to Improve Recommended Breast Cancer Screening and Reduce Racial and Geographic Disparities Among Women.

This paper examines the effectiveness of using personal health records (PHRs), which contains detailed health information to improve the use of recommended screening mammography among women at potential risk for breast cancer. It also explores the potential of PHR in reducing disparities in recommended mammography use experienced by minority and underserved women. The primary data used for this study were obtained from the 2015 Health Information National Trends Survey, and they were supplemented by the 2016 Area Health Resource Files. The study sample included women aged 40-75 years with no prior diagnosis of cancer. Because the use of PHRs as a key predictor of breast cancer screening may be endogenously determined, we used the instrumental variable (IV) approach to correct for estimation bias. We found a significant and positive association between the use of PHRs and recommended mammography use among women, with the likelihood of mammography screening increasing with more frequent use of PHRs. Furthermore, the effects of PHR use on mammography screening were found to be greater among Hispanic and Black women and those living in non-metropolitan areas compared with White women and those living in metropolitan areas, respectively. The use of PHRs for health information seeking can empower women at potential risk for breast cancer to participate in recommended screening mammography, particularly among those underserved and racial/ethnic minorities. Policymakers should consider developing policies and programs that can promote PHR use by women, especially medically underserved and minority women.
