Adherence to the Women's Preventive Services Guidelines in the Affordable Care Act.

Objective: To assess the adherence of women's health providers in New Mexico to the Women's Preventive Services Guidelines and to examine how providers' knowledge, attitudes, and external barriers are associated with adherence.

Design: Cross-sectional, descriptive survey.

Setting: New Mexico.

Participants: Women's health providers in New Mexico, including nurse practitioners, certified nurse-midwives, and family practice and obstetrician-gynecologist physicians.

Methods: Participants completed a self-administered survey to measure knowledge, attitudes, external barriers, and adherence to each of the eight guidelines. Adherence was defined as following a guideline more than 90% of the time.

Results: The response rate was 22% (399/1,798). Among the eight guidelines, participant adherence ranged from 17.2% to 88.4%. Only 39.7% of participants indicated adherence to most of the guidelines (four or more). Overall, provider adherence was directly associated with familiarity with the guidelines (odds ratio = 3.69; 95% confidence interval [1.96, 6.96]), self-efficacy to implement them (odds ratio = 4.25; 95% confidence interval [2.21, 8.20]), and younger age (odds ratio = 0.97; 95% confidence interval [0.94, 1.00]).

Conclusion: Adherence to the Women's Preventive Services Guidelines by providers in New Mexico is variable and, for many recommended practices, less than optimal. New targeted implementation strategies are needed to address barriers to adherence.
