Methodology of revision of Korean national cancer screening guideline.

Abstract

The National Cancer Screening Program (NCSP) was established to provide cancer screening services for low-income Medicaid recipients in 1999. Since then, the NCSP has expanded its target population to include National Health Insurance beneficiaries. Currently, the program targets the five most common types of cancer in Korea: stomach, liver, colorectal, breast, and cervical cancer. The National Cancer Center has been involved in developing and revising the practice guidelines for the NCSP in collaboration with the Ministry of Health and Welfare and related academic societies. The main methodological principles of development were determined as follows: an evidence-based approach to the development of recommendations on cancer screening was used, that the recommendation could be drawn by an adaptation process if evidence-based current reliable clinical practice guidelines were available, and that the level of evidence was assessed by methodologies. The process of recommendation development was divided into planning, development, and finalization steps. Planning tasks consisted of selection of clinical practice guideline topics, organization of a clinical practice guideline development group, reviewing the existing clinical practice guidelines, establishment of development plans, and definition of key questions. Development tasks consisted of steps including searching the literature evidence base, assessment of the quality of evidence, integration of evidence, and formulation of recommendations and deciding on the recommendation grade. The finalization tasks included external review, up-dating of the plan, and publication of the clinical practice guidelines.
