Development and Application of a Reference Manual for Diagnosis and Rational Use of Antimicrobial Agents for Outpatient Primary Care (Digestive System Part): A Delphi Study.

Purpose: To establish a concise and easy-to-understand reference manual for outpatient primary care providers, promoting correct diagnosis of digestive system diseases and rational antimicrobial use. Methods: The establishment of the manual encompassed two processes: the development of a draft manual and the validation of the manual. The development process was based on a literature review and expert discussion. The manual comprises portions for disease diagnosis and rationality of antimicrobial use. The validation process employed a two-round Delphi technique, collecting consensus through paper-based or mail-based communications. The response of the Delphi group was assessed by the level of authority and commitment of the panelists and the degree of agreement among them. Furthermore, the manual was preliminarily applied among primary care physicians. Results: A total of 29 panelists completed the Delphi working process. They were authoritative in their professional fields with authority coefficients of 0.813 and 0.818 for the two portions of the manual, respectively. The level of commitment of the panelists was measured by response rates, which were 100.00% and 96.67% for Round 1 and 2. After two rounds, a consensus was achieved with the consensus rates for the two portions of the manual being greater than 65% and 70%, respectively. Kendall Conclusion: Based on a collective consensus of professionals, a reference manual has been established, to provide a concise and easy-to-understand guide specifically for physicians and pharmacists in outpatient primary care. It could facilitate rapid learning to improve the accuracy of diagnosis and treatment for digestive disorders.
