Executive Summary of the 2023 Adult Position Development Conference of the International Society for Clinical Densitometry: DXA Reporting, Follow-up BMD Testing and Trabecular Bone Score Application and Reporting.

After 15 months of preparation by task force chairs and teams, ISCD's 9th Position Development Conference (PDC) convened in Northbrook, IL, USA on March 28th and 29th, 2023 to approve new ISCD Official Positions in the topic areas of DXA Reporting, Follow-up BMD Testing and TBS Application and Reporting. Three teams of participants work to bring the PDC to fruition: the Steering Committee, Task Forces and Chairs, and the Expert Panel. To reach agreement on draft Official Positions, the PDC follows a scripted process with the UCLA/RAND Appropriateness Method (UCLA/RAM) as its foundation. Multiple rounds of data review, public debate and voting resulted in 32 new or modified Official Positions. Six companion position papers are also published along with this Executive Summary, serving as the detailed substantiation for the Official Positions. This Executive Summary reviews the personnel groups, activities and products of the 2023 PDC, with the entirety of the updated 2023 Official Positions presented in Appendix A.
