Abstract : 

Objectives: To evaluate the therapeutic adherence of patients with prevalent pathologies, identifying related factors. To quantify improvement in adherence achieved through professional pharmaceutical services (PPS). To establish satisfaction with the service.

Methods: Design: Phase 1: a single-center, descriptive, longitudinal study carried out between 3/18 and 4/10/2019. Phase 2: Quasi-experimental study with no control group, with educational intervention and PPS, medication use review (MUR) and Personalized Dosage System (PDS), October-November/2019.

Subjects: Elderly patients with dyslipidemia, high blood pressure or diabetes, who went to the pharmacy and agreed to participate. For the second phase, patients who were non-adherent in the first phase were selected.

Variables: adherence (measured with the Morisky-Green test), satisfaction with the service. Demographic variables.

Results: Phase 1: 101 patients, mean age 69 years. 50.5% male. The proportion of non-adherents was 55.4% 40 (71.4%) at some point forgot to take their medication. Adherence was not related to sex, age, companionship status, number of pathologies or level of education (p > 0.05).

Phase 2: MUR: The percentage of non-adherents decreased to 67%. PDS: Nine of the 10 patients were adherent at the end of the study. One patient was non-adherent due to sporadically forgetting to take the medication.

100% of the satisfaction survey respondents were “very satisfied,” and would continue to visit the pharmacy and recommend it.

Conclusions: ladherence to treatment was low, less than 50%. No relationship was found with the factors analyzed. 

Conducting an MUR and PDS improves adherence. The degree of satisfaction was 100%. All patients wanted to continue with the service.
