Popis: Pharmacotherapy is an essential strategy for the treatment of many medical conditions especially chronic disease and often involves multiple medications being used simultaneously. Increasing the use of medications may pose some challenges to safe and effective drug therapy and if not identified and prevented by the pharmacists eventually can lead to drug-related problems (DRPs). The present study aimed to examine the incidence of DRPs in Iranian patients and to evaluate patients' adherence to the clinical pharmacist interventions as well as the physicians' acceptance of these recommendations.This study was conducted in a university-affiliated outpatient pharmacotherapy clinic over a 22-month period. Patients aged 18 years and older with at least one chronic disease receiving at least four medications were included in the study. The patients were interviewed by a clinical pharmacist for comprehensive medication review. DRPs were identified using the DOCUMENT classification system. Recommendations were provided by the clinical pharmacist including interventions involving patient and/or physician to resolve DRPs. The patients were followed up after 2 weeks to evaluate their compliance and physician acceptance of clinical pharmacist recommendations.Two hundred patients were included in this study. Overall, 875 DRPs were identified with an average of 4.37 per patient. The most prevalent DRPs were related to patient education or information (22.8%), undertreated indications (17.4%) and patient compliance (17.2%). The most common drugs associated with DRPs were alimentary and metabolism (22.2% of DRPs) followed by the cardiovascular system (19.2%) and nervous system (9.6%) medications. The DRP incidence correlated with gender only and was higher in females (p = 0.019). The clinical pharmacist provided 912 interventions with an average of 4.56 and 1.04 interventions per patient and per DRPs respectively. Patient education (41.3%), medication initiation or discontinuation (24.5%), and non-pharmacological interventions (12.9%) were the most common clinical pharmacist interventions. Out of 912 interventions, 665 were followed up, out of which 427 were patient dependent and 228 involved physicians. The patient's compliance with clinical pharmacist recommendations was 81.2%. The physician acceptance rate of the recommendations was 44.1%.The study shows that especially designed services such as pharmacotherapy clinics running by clinical pharmacists are necessary to detect and resolve DRPs in an effective way. The high compliance rate of the patients indicates patients' confidence in the clinical pharmacist services provided in the pharmacotherapy clinic. The low acceptance rate of the physicians highlights the need to improve interprofessional collaboration between clinical pharmacists and physicians in an outpatient setting.
