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' perceptions of the Unified Health System (SUS), which has already generated publications in previous phases. The aim was to assess users' 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'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's strengthening and improvement.
