Drug-Related Problems Detected in Complex Chronic Patients by Community Pharmacists of Catalonia: Perception of the Person-Centred Approach Necessity

Community pharmacies are healthcare settings in which pharmacists are in an ideal position to carry out pharmaceutical care. The aim of this study was to analyse the number, type and groups of drugs that caused drug-related problems (DRPs) detected in complex chronic patients who are outpatients, the interventions and actions of community pharmacists and their impact on patient medication adherence. The study was designed as a secondary analysis of a multicentre study in the field of primary healthcare and community pharmacies in Catalonia (Spain). The patients who took part were divided into two groups by the primary care physician depending on whether or not they were considered likely to receive their medication through a monitored dosage system (MDS) based on pre-established criteria. Patients underwent 12 months of follow-up by community pharmacists. The prevalence of DRPs among the studied complex chronic patients was high (n = 689). The most identified DRP was nonadherence (31.20%). In the MDS group, results showed a statistically significant increase of 21% in the number of adherent patients with respect to the baseline visit (p-value = 0.0008). Community pharmacists can have an important role in addressing DRPs and optimizing the safety and effectiveness of medications for these patients and in involving them in their own health conditions.
