  • 4. Introduction Background Mongolia is considered to be one of the countries with a sufficient supply of health professionals in terms of proportion to the size of the population, especially in urban areas. However, the problem of dense population in urban areas and internal migration has deteriorated the quality, accessibility, and load of healthcare services. In this situation, it is claimed that the stress and depression driven by over workload of health professionals has somewhat negatively influenced their attitude towards work and job satisfaction. Other factors, such as the number of the patients, duration of medical checkups, procedures, consultations, and other additional functions, like serving patients with special needs, can lead to significant job stress. Significance There was no study dealing with job stress and job satisfaction for health professionals in Mongolia 4

  • 13. Introduction Background Medication errors are increasing The Clinical Decision Support System (CDSS) for drug prescriptions was developed by integrating the computerized physician order entry (CPOE) system to support doctors and pharmacists in making correct decisions on prescribing drugs in line with the prescription guidelines by the Health Insurance Review Agency (HIRA) Significance This is the first attempt to evaluate effectiveness of CDSS for drug prescription in Korea Use of DeLoneand McFarlanmodel for performance evaluation of CDSS 13
  • 14. Objectives The purpose of this paper is to analyze the performance of the CDSS with respect to system quality, information quality, and user satisfaction to reduce prescription error Specific objectives are: To identify the factors influencing CDSS performance To analyze association between quality measures and user satisfaction 14
  • 15. Subjects A questionnaire was designed by structuring primary evaluation areas first and then more detailed sub-areas in each primary area. The survey was conducted by mail or by visit for 6 weeks from April 20 to May 29, 2009, for the pharmacists from 38 hospitals using the CDSS. Hospitals were selected by stratified random sampling Research design is cross-sectional design A total of 84 questionnaires were returned from 22 users (response rate of 58%). Of them, 77 were used for the analysis, excluding 7 that were found unusable for statistical analysis. 15
  • 16. Model and Statistical Analysis Based on the Deloneand McLean framework, we evaluated the success of the CDSS by using two quality measures (system quality and information quality) as independent variables; and three performance measures (user satisfaction and organizational impact) as dependent variables for the multiple regression analysis (Figure 1). Chi-square analysis with cross-tabulation was performed to analyze the specific associations among two quality measures and three measures of user satisfaction (information satisfaction, system satisfaction, and willingness to recommend to others). We also analyzed the associations between two quality measures and improvements in drug safety as a performance measure of organizational impact by using Chi-square 16
