Access to medicines in the Brazilian Unified Health System's primary health care: assessment of a public policy.

In 2008, the Programa Rede Farmácia de Minas (RFM, literally translated: 'Minas Gerais Pharmacy Network' program) was created as a strategy to expand access to medicines. Aim: Measure access to medicines in public pharmacies through comparison between municipalities that joined or not the RFM. Materials & methods: Cross-sectional, evaluative study, gathering information from a representative sample of the municipalities in Minas Gerais between July 2014 and May 2015. The Poisson regression results were obtained by calculating the prevalence ratios. Results: Adequate access to medicines in Minas Gerais was 69.9%, being 75.8% in municipalities with and 69.2% without the RFM. The municipalities with the RFM showed statistically higher percentages in the Availability, Adequacy/Accommodation, and Acceptability dimensions. Conclusion: RFM appears an efficient strategy for promoting access to medicines.
