지역병원에서의 중복처방경고시스템 개발을 통한 약품사용 안전성 개선방안

Abstract

Purpose: We desired to detect the cause of the duplicate prescriptions which occurrs in Cheong-ju St. Mary's hospital, and to develop effective warning program which can prevent the duplicate prescriptions. The purpose of this study is to reduce duplicate prescription, ultimately, to elevate the safety and appropriateness of drug use by this system. Methods: As preliminary research before developing a program, the duplicate prescriptions which transmitted with FAX from community pharmacies to the Cheongju St. Mary's Hospital were retrospectively analyzed. We developed warning program for the duplicate prescriptions. This warning program was operated from August 2006. The duplicate prescriptions retrospectively analyzed for the period of 2 months prior to and after the implementation of duplication warning program. After improving a program, data analysis was continued in 2007. Results: After warning system for the duplicate prescriptions was implemented, the average daily frequency of the duplicate prescription was reduced from 1.16 cases to 0.47 cases. The daily frequency of the duplication generated from different ambulatory clinics was decreased from 0.56 cases to 0.14 cases(75% reduction). The daily frequency of duplication generated from the single ambulatory clinic was decreased from 0.6 cases to 0.33 cases (45% reduction). The daily frequency of same-drug coded duplication decreased from 0.84 cases to 0.39 cases (53.6% reduction). Daily frequency of duplication in the drugs with similar medical effect was decreased from 0.08 cased to none. Conclusion: This warning program for the duplicate prescriptions reduces risk for drug duplication when a patient being treated at two or more ambulatory clinics or when prescribing the many kinds of drugs inside a prescription.
