Developing a Methodological Framework and a Dissemination Plan for Herb-drug Interactions-related Clinical Practice Guidelines

The goal of this observational study is to develop a methodological framework for clinical practice guidelines (CPGs) related to herb-drug interactions (HDIs). It will also learn barriers and facilitators of disseminating HDI-related CPGs and formulate a dissemination plan. The main questions it aims to answer are: 1. develop a methodological framework for HDI-related CPGs using a Delphi method; 2. identity barriers and facilitators of disseminating HDI-related CPGs through semi-structured interviews and formulate a theory-informed dissemination plan to promote the uptake of CPGs locally and internationally. * Participants in the Delphi survey will engage in a consensus development to determine the framework of HDI-related CPGs, including key characteristics and components of this framework. * Participants in the semi-structured interviews will be interviewed on the following topics: their experiences in searching for evidence and CPGs related to HDIs; barriers and facilitators encountered when obtaining information from existing CPGs; their views on the ideal platform for disseminating HDI-related CPGs.
