GRADE Guidance: Update on Developing Good Practice Statements in Guidelines.

Despite published guidance by the GRADE (Grading of Recommendations Assessment, Development and Evaluation) Working Group on the use of good practice statements (GPSs), their appropriate development remains challenging. This article provides updated guidance with nuanced operationalization. The updated guidance was developed on the basis of examples and iterative discussions. The lead authors refined the approach according to the feedback from GRADE Working Group meetings and presented the summary of the results to all attendees of the GRADE Working Group meeting for feedback in September 2023 and for final approval in September 2024. The 5 signaling questions from the original guidance were leveraged, and the authors recommend that guideline developers select relevant Evidence to Decision criteria to assess the potential downstream consequences of implementing the statement. They have updated the definition of a GPS, classifying GPSs into the following 3 categories: those grounded in ethics and human rights; those grounded in essential principles, practices, and protocols; and those grounded in established scientific evidence. Practical examples accompany the steps as they relate to each type of GPS. In addition, the authors introduce a tool to streamline GPS development and enhance the reporting process. This GRADE guidance article provides an update on when and how to develop a GPS. Adherence to the guidance will add to the trustworthiness of guidelines and may facilitate reducing the inappropriate use or overuse of the GPS.
