Periodic Health Examination and Prevention Guidelines for Koreans were first proposed since 1988. Based on that guideline, clinical preventive services has been applied to clinic population in a few University Hospitals since 1991. In 1995, LHMP development committee in Korean Academy of Family Physician Society first published evidence based clinical practice guidelines and updated the guidelines in 2003. Lifetime Health Maintenance Program (LHMP) commitee represents efforts to take a more updated evidence-based approach to the development of the third updated clinical practice guideline in 2009. We focused on approaches that can reliably assess the extent of updating required, a model of limited literature searches with modest expert involvement to reduce the cost and time.
