Setting: Primary Care

 

 

- The aims of this study were to determine prevalence and predictive

factors of initial medication nonadherence (IMNA)- defined as not obtaining a medication the first time it is prescribed in the Catalan health system

(Spain)

- 1.6 million patients with 2.9 million prescriptions were included

- Total IMNA prevalence was

17.6% of prescriptions - Predictors of IMNA are younger age, American nationality, having pain-related or mental disorder and being treated by a substitute/resident general practitioner in a resident training center.

- Attempts to strengthen trust in resident general practitioners and improve motivation to initiate a needed medication in the general young and older immigrant population should be addressed in Catalan PC. Aznar-Lou I et al. (2017)
