Drug Utilization Review (DUR) is known to play an important role to improve appropriateness of drug prescriptions. This retrospective, observational study was conducted to compare prescription patterns after installation of Computerized DUR Program (Drug Information Framework-$Korea^{TM}$) (Jan-Mar 2008; After) to before DUR program (Jan-Mar 2007: Before). 8 physicians affiliated in the S University Hospital were enrolled in the study and their 3 months' prescription data were analysed for drug prescription trends and DUR conflict events per 7 DUR screening modules (drugdrug interaction, therapeutic duplication, allergy, dosing, disease contra-indication, geriatric contra-indication, pediatric contra-indication). Average rate of DUR modules usage in 2008 (After) were 0.72. Average number of prescription drug per patient were reduced from 5.6 (Before) to 3.8 (After), and DUR program seemed to effect positively on physician's prescription related decision process. Overall DUR conflict events occurred by 8 physicians for 3 months were 17,923 Before and 20,057 After DUR program, and DUR conflict events per prescription were 2.8 Before and 2.9 After, respectively. Therapeutic duplication (37%), geriatric contra-indication (34%) and dosing (18%) were high ranked DUR conflicts. As the study was not sufficient to show a consistent trend to reduce DUR conflicts After, another study to confirm it's effectiveness would be recommended. This study would be of help to develop awareness of DUR program to healthcare providers.

Medical errors such as adverse drug event, improper transfusion, wrong-site surgery, mistaken patient identity and so on commonly occur at health care practice. Information technology, like Drug Utilization Review(DUR) system which reviews, analyzes, and interprets medication data when prescribing, can play a key role in reducing such medical errors and improving patient safety. Korean Government has guided all hospitals to implement concurrent DUR(cDUR) system, which is the first case worldwide in that all healthcare providers have to use cDUR system when prescribing. This paper introduced a case study that a tertiary hospital has integrated the cDUR system into its comprehensive Hospital Information System(HIS) and analyzed the whole prescription data during a week right after adoption of cDUR system. Considering technical strength and weakness, the cDUR system was integrated into the HIS, using Broker Servers for minimizing doctors' anxiety. As the quantitative analysis of the whole prescription data, DUR conflict events, which mainly included duplicate medications and contra-indicated drug interactions for outpatients, were 2.77%. Although only 0.7% is for the contra-indicated drug interactions, it will be greatly devoted to achieve the purpose of DUR such as improving patient safety.
