|The objective of this study was to develop computer program for evaluating and detecting high alert drugs (HAD) prescribing errors in inpatients. The efficacy of the program in prescribing error detection was compared with the routine prescribing error detection of the pharmacy department by using the retrospective data of 693 HAD orders of 583 patients admitted to 2 medical wards and 2 surgical wards during 1st July to 30th September 2007.
The results showed that the computer program could detect 122 HAD prescribing errors; meanwhile, the pharmacy routine method found only 1 HAD prescribing error which was significantly different (p-value <0.001). The study of the feasibility of using the computer program in actual practice was determined by order processing time and user satisfaction evaluation. The study found an average of 2.14 minutes per the evaluation of one order. The opinions on user satisfaction of 12 pharmacists who used the computer program indicated that the level of satisfaction was high for the topics of the precision of the data and the appropriateness of the drug information database used, the precision and completion of the evaluated topics, the capacity of the computer program to detect prescribing errors in HAD orders before they reach the patients and the overall advantage of using the program. The level of satisfaction was moderate for the pattern and aesthetic property of the program, the appropriateness of operation time, complexity in operation and practicality. The results suggested that the program should be developed further for practicality in future use.
