Aim: Creation of a single indicator of access to medicines. Methods: Data collection was performed with individuals who obtained their medication from either public and/or private pharmacies. A Likert scale was used to measure the importance and satisfaction in relation to various access dimensions. Results: A total of 580 individuals were interviewed. Overall, participants attributed very similar importance scores to the dimensions of access to medicines. The results of the mean score of each dimension showed a statistically significant difference according to the type of pharmacy that the participant visited. Conclusion: This developed indicator will enable a review of access to medicines, making comparisons possible as well as improving decision making about public policies in the field of Pharmaceutical Services.
