Introduction to methodology for the development of an integrative medical service model

BACKGROUND: The purpose of this article was to present a valid and reliable theoretical framework and method for the development of an integrated medical service model for the four major diseases. METHODS: Methodologies for each process were presented based on three theoretical frameworks. The three theories were the double diamond process model, the Donabedian model, and the International Classification of Functioning, Disability, and Health model. Based on this, in the process of problem finding, a literature review, service user questionnaire, and interview methods were applied. For problem definition and solution, expert focus group interview and expert Delphi methods were applied. The subjects of the study were mainly selected from experts for each disease and users of medical services. For literature review, systematic literature review and subject range literature review were conducted, and for analysis, a meta-analysis was carried out. In the case of focus group interview and Delphi, the validity and reliability of domain derivation and sub-items were analyzed by applying the qualitative analysis method. RESULTS: To develop an integrative medical service model, a theoretical framework and a systematic methodology were needed, and case studies were performed to prove its validity and reliability. This showed that the development of a medical service model needs to follow a scientific procedure. CONCLUSIONS: By introducing methodological approaches and procedures for the development of an integrated medical service model for the four major diseases, the researchers provided basic information on model development.
