WHAT IS KNOWN AND OBJECTIVE: This study aimed to investigate the prevalence and the type of drug-related problems (DRPs) in ambulatory patients and identify factors that may be associated with risk of DRPs. METHODS: Consecutive patients were enrolled from pharmacist outpatient clinics between January 2018 and June 2019. The pharmacists performed a comprehensive assessment of the patient's drug therapy. The DRPs and recommendations were evaluated using the DOCUMENT classification system. RESULTS AND DISCUSSION: The study population consisted of 248 patients with a mean age of 72.55 ± 6.29. The patients had a mean of 7.55 ± 4.72 ongoing medications during patients' routine clinic visits. A total of 1188 DRPs were identified during the study period. An average of 4.79 DRPs per patient was detected. Sixty-two different traditional Chinese patent medicines (TCPMs) contributed to 102 DRPs. Drug selection (24.9%) was the most common DRP followed by under treated (24.2%) and monitoring needed (24.2%). The number of medications taken was the significant factor for DRPs. Pharmacists made 1092 recommendations to address the DRPs (an average 0.92 recommendations per DRP). A change in therapy was the most common recommendation (43.6%), followed by the category 'monitoring' (28.6%). The overall acceptance rate of clinical pharmacist recommendations was 88.7%. More than a half (51.6%) of all interventions were assigned a moderate level of clinical significance. WHAT IS NEW AND CONCLUSION: Drug-related problems were commonly observed among ambulatory Chinese patients. Clinical pharmacists had a valuable role to play in identifying and solving the DRPs.
