Development of a Decision Support Tool for Acute Appendicitis

TLDR: In this paper, the authors describe the development of a new decisions support tool (DST) for acute appendicitis and place it in the context of international guidelines for decision aid development.

Abstract: Background: Multiple randomized controlled trials have shown that it is safe and effective to treat appendicitis with antibiotics or surgery. There are no tools available to assist surgeons and their patients in choosing the optimal treatment for each individual patient. Here we describe the development of a new decisions support tool (DST) for acute appendicitis and place it in the context of international guidelines for decision aid development. Methods: The stakeholder engagement and development process for the DST is described. The DST and its development process are placed in the context of the International Patient Decision Aid Standards (IPDAS) and the DEVELOPTOOLS checklist for a user-centered design process. Results: A diverse group of over 60 stakeholders were involved in the needs-assessment, development, and evaluation of the DST. The development process met 11/11 of the scored items on the DEVELOPTOOLS checklist. Of the 34 applicable IPDAS items, the current version of the DST meets 31 of them including 6/6 qualifying criteria, 6/6 certification criteria, and 18/22 quality criteria. Conclusions: The novel appendicitis DST was developed with the input of multiple stakeholders. The development process and the tool itself complies with best practices recommended by the IPDAS.
