Objective: South Korea made a list of potentially inappropriate medications (PIMs) for elderly patients in 2015 and has prompted medical professionals to prescribe proper medication by using the drug utilization review (DUR) system. It has been three years since the system was introduced, but related studies have rarely been conducted. This study aimed to evaluate the effect of the DUR system on the prescription of PIMs for elderly patients. Methods: The data on the prescription of PIMs for elderly patients (${\geq}65$ years) who received medical treatment between March 1st and May 31st in 2015 (before introduction of the DUR system) and who received medical treatment between March 1st and May 31st in 2018 (after introduction of the DUR system) were retrospectively collected from electronic medical records. Results: The prescriptions of PIMs decreased from 3,716 (7.7%) to 3,857 (6.9%) (p < 0.001). The prescription of escitalopram and paroxetine, among selective serotonin reuptake inhibitors, increased significantly, and that of short-acting benzodiazepines also increased significantly from 454 (0.93%) to 624 (1.2%). Conclusion: Prescription of PIMs for elderly patients significantly decreased (p < 0.001) after the DUR system was introduced. Further expanded studies of PIMs need to be conducted for the safety of elderly patients.

Background: Serotonin syndrome is a life-threatening disease if not appropriately treated. This study aimed to investigate the prescription status of contraindicated drug combinations that cause serotonin syndrome and identify the related factors. Methods: A cross-sectional study was conducted using nationwide claims data. Adult patients taking serotonergic drugs with Parkinson's disease or mental disorders were selected. Based on international medical databases (MDBs) and the Korean Drug Utilization Review (DUR), the status of prescribing contraindicated drug combinations that induce serotonin syndrome, the related factors, and the difference between international MDBs and the Korean DUR were analyzed. Results: Of the 49,773 study subjects, 163 (0.3%) were prescribed contraindicated serotonergic drug combinations based on international MDBs, and among them, only 105 (64.4%) were contraindicated by the Korean DUR. Positive influencing factors for prescribing contraindicated drug combinations include patient age between 65 and 74 and physician's specialties (neurologists, and orthopedists). Negative influencing factors were physician's specialty (internists) and medical institution (primary institutions). Conclusion: Despite the implementation of DUR, 3 out of 1,000 study subjects received contraindicated drug combinations that caused serotonin syndrome. Hence, it is necessary to comply with the DUR and improve it in accordance with international MDBs.

The computerized prospective Drug Utilization Review (DUR) program supported by the Korean government has provided alerts to physicians and pharmacists since December 2010. This study aims to propose and apply the tiering system in "drug combinations to avoid (DCA)" and "age-precaution" alerts based on severity to improve the compliance of users. To propose the severity and clinical importance of 647 DCA alerts and 140 age precautions, a Delphi evaluation survey was conducted. An expert panel comprising 5 clinical pharmacists and 5 physicians were participated in mail surveys. Based on the results of Delphi survey, DCA pairs were classified into 3 groups; group 1 (70.6%), 2 (26.9%), and 3 (2.8%). Drug-age precaution ingredients were also classified into three groups; group 1 (53.6%), group 2 (40.7%), and group 3 (5.7%). When this grouping was applied to claim data from 2011 to 2013, the majority of alerts had occurred in the groups of high severity. Presenting DUR alerts with severity level is expected to improve the compliance of clinicians. The implementation of tiering system in DUR criteria should be considered.

This study was to determine the inappropriate drug use in pediatric outpatients who received 2 or more prescriptions on the same day. Retrospective drug utilization reviews (DURs) were implemented to samples obtained from national health insurance claims data during December 2008 to February 2009, using 5 DUR criteria (duplication, drug-drug interaction, drug-disease interaction, drug-age contraindication, incorrect dosage) established in the Drug Information Framework (DIF)-$Korea^{TM}$, DUR program. Among 38,451 claims analyzed in the study, 74.7% had more than one conflicts in the 5 DUR modules. Among 16,472 patients analyzed, 49.6% had conflicts with duplication criteria composing of ingredient duplication (23.3%) and therapeutic class duplication (39.6%). Incorrect dosages were found in 73.6% of patients and under-dosage conflicts accounted for 59.9%, which was higher than over-dosage conflicts (38.3%). In this study, inappropriate drug prescriptions such as under-dose, pediatric contraindication and therapeutic duplication were prevalent in pediatric outpatient settings, suggesting much more awareness to the society, to prevent drug related problems in a vulnerable pediatric group.

의약품을 사용할 때 나타나는 부작용은 국민의 건강을 크게 위협할 수 있다. 현재 의약품 부작용에 대한 보고가 매우 미흡한 것이 현실이다. 이에 현재 약국에서 사용하고 있는 의약품 사용평가(DUR:Drug Utilization Review)에 의약품 부작용 보고를 연계하게 된다면 활성화될 수 있다. 의약품 사용평가가 활성화되어 있는 미국 의약품 관리 체계 연구를 통해 의약품 부작용 보고 활성화 방안을 찾을 수 있다. 약국에서 의약품 관리 프로그램으로 사용되는 'Pharm IT 3000'에서 의약품 부작용 보고의 활성화 방안을 연구해 보았다. 문헌연구와 실제 프로그램 운영 방식 연구를 통해 Pharm IT 3000 처방 조제 현황 항목에 의약품 사용평가를 연동시켜 부작용 보고가 편리하게 되는 방안을 찾게 되었다.

Objective: The objective of the present study was to evaluate the effects of implementing a systematic Drug Utilization Review (DUR) system on contraindicated drug use and pharmaceutical expenditures in Korea. Methods: A literature search was conducted using search engines such as PubMed, EMBASE, NDSL, and RISS for relevant systematic studies. The database search was performed and updated in April 2018. Two independent reviewers evaluated the abstracts to find potentially eligible articles. Results: In total, 1433 potentially eligible studies were selected, and 11 articles were eventually shortlisted for inclusion in the present review system. The outcome showed that contraindicated drug use decreased after implementation of the DUR system in Korea. The analysis also showed that the DUR system contributed to a reduction in pharmaceutical expenditures. Conclusions: Our study showed that implementing the DUR system reduced both contraindicated drug use and pharmaceutical expenditures in Korea.
