Identifying an association between socio-demographic factors and breast cancer screening adherence in a federally qualified health centre sample in the United States. A retrospective, cross-sectional study.

Federally Qualified Health Centres (FQHC) are community-based centres in the United States, intended to fill a gap in care for underserved populations, including Medicaid patients and the homeless. Because of the Affordable Care Act, passed into law in 2010, there was a 29% increase in Medicaid enrolees nationally. One service offered at FQHCs is breast cancer screening. Breast cancer screening has been shown to have the lowest adherence levels among low-income women and homeless women. As they serve patients with socio-economic barriers, FQHCs are a vital resource in ensuring access to such screening. This study aimed to identity an association between socio-demographic factors and breast cancer screening adherence in FQHC patients that included the homeless. This exploratory, cross-sectional, retrospective study looked at encounter level data from a FQHC in a major metropolitan (Chicago, IL) area from January 1st, 2017 through December 31st, 2018. Data were collected in January of 2019. This was a convenience sample. Association was tested through bivariate chi-square tests and multivariate logistic regression analysis, investigating the association between socio-demographic characteristics and compliance (Yes/No) for breast cancer screening. Results showed age (55-59; 65-69) and homeless status (doubling-up, transitional) showed a positive association with breast cancer screening, while insurance status (self-pay) had a negative association. Age, homeless status and insurance type were significantly associated with adherence. Demographic characteristics in the homeless population can be used to identify nonadherence.
