Memphis Researchers Examined Gender Difference in Cost-Related Non Adherence of Medication among Patients with Cardiovascular Conditions

A study led by Dr. Soumitra Bhuyan, an assistant professor of health systems management and policy at The University of Memphis School of Public Health, published a study that examined the effect of gender on three types of cost-related non-adherence (CRN) of medication (skipped medication doses to save money, took less medication to save money, and delayed prescription filling to save money). After adjusting for the confounding factors, the study found significant gender disparities in CRN among cardiovascular patients.

Dr. Satish Kedia, a professor at Memphis and a co-author of this study, reported that in this nationally representative sample of individuals with a CVD condition, who were prescribed at least one medication in the last 12 months, “women with CVD were more likely to experience CRN compared to men”. A concern brought up in this study was that having health insurance did not decrease the problem or risk of CRN. Dr. Cyril Chang, a professor of economics at the Fogelman College of Business and Economics, stated that future research needs to “evolve beyond having health insurance and better income and to other to sociodemographic-related and behavioral risk factors and/or psychosocial reasons for CRN.”

The authors contend that continued monitoring in women with CVD and individuals with poor health are needed as part of the development and improvement of patient-centered interventions. The results indicated that the higher rates of CRN in women might explain gender-related disparities in health outcomes, which should be examined further. To improve medication adherence, additional support should be provided to these disadvantaged groups. The current programs intended to address adherence issues in women should account for cost-related barriers to improve adherence in this patient population.  This study is a collaboration between the University of Memphis, University of Wisconsin, University of Nebraska Medical Center, and London School of Hygiene and Tropical Medicine. The study used most recent data (2011-2014) US National Health Interview Survey (NHIS) maintained by the National Center for Health Statistics.

The findings from this study were published in January-February Issue 2017 in the Journal of Women’s Health Issues Volume 27 Issue 1. To read more, click:
