title: Applying a multiple screening program aided by a guideline-driven computerized decision support system - a pilot experience in Yun-Lin, Taiwan.
abstract: OBJECTIVE
  Although preventive tools decrease morbidity and mortality and promote health, these services are often underutilized. The purpose of this study was to create a workflow for an outpatient setting that incorporated a computerized decision support system to implement preventive recommendations as well as to evaluate its impacts on facilitating preventive care.
  
  
  METHODS
  Subjects visiting National Taiwan University Hospital Yun-Lin Branch were evaluated by a questionnaire, which contained items to trigger production rules to check the eligibility of screening for high coronary risk, diabetes mellitus, lipid disorder, hypertension, obesity, tobacco use, depression, colorectal cancer, breast cancer, cervical cancer, and osteoporosis. Patients were given health information about the diseases they were at risk for and the merits of preventive measures, scheduled for a clinic visit, and arranged to have access to screening tools. Physicians were prompted with clinical reminders on the encounter. The over-all effectiveness of 11 components in this screening program was evaluated in terms of expected life saving. The cost-effectiveness ratio was represented in US dollars per life-year saved.
  
  
  RESULTS
  A total of 283 men and 199 women were identified to need one to six preventive interventions during a 2-month period. Preventive consultation was arranged and screening tools were performed. It was estimated that 412-1014 subjects would be needed to attend the program so as to save one life. The cost-effectiveness ratio ranged from 30,000 US dollars to 40,000 US dollars per life-year saved.
  
  
  CONCLUSIONS
  A computer-aided screening program driven by the US Preventive Services Task Force recommendations has been successfully implemented in Yun-Lin, Taiwan, and provided useful information about local epidemiology and implications for future health policy making.
