Users’ Perceptions of Access to and Quality of Public Health Services in Brazil: A Cross-Sectional Study in Metropolitan Rio de Janeiro, Including Pharmaceutical Services

Background: This study evaluates one of the five regions of the state of Rio de Janeiro, Brazil, as part of a broader research project examining users&rsquo: perceptions of the Unified Health System (SUS), which has already generated publications in previous phases. The aim was to assess users&rsquo: perceptions of the SUS regarding access to and the quality of public health services, including pharmaceutical services, in the Metropolitan Region of Rio de Janeiro State. Method: A cross-sectional study was conducted between January and August 2024 with 200 participants, using a 66-item survey addressing access to and the quality of SUS services, appointment scheduling, medication acquisition, and the pharmacist&rsquo:s role. Associations between variables were investigated using the Pearson Chi-Square Test in R software. Results: Frequent SUS users rated access as very good/good (p = 0.002) and overall quality as very good/good (p = 0.045). Reported challenges included the need for improved infrastructure (48.5%), better professional qualifications (30.6%), and easier access to medicines (16.8%). Higher ratings were given by those who used the SUS more frequently, and, in general, there was a tendency for participants with lower socioeconomic conditions to provide more favorable assessments of access to public health services (p = 0.024). Conclusions: A universal health system should cover diverse regions with unique needs. However, 49.4% of participants stated they never received information on how to store their medicines, and 42.3% reported never encountering a pharmacist in public pharmacies. Further ongoing studies assessing user perceptions are essential to ensure users play a central role in health decision-making, contributing to the system&rsquo:s strengthening and improvement.
