OBJECTIVES: To gather the perspectives of APS ACTION members regarding the strengths and limitations of Damage Index for Antiphospholipid Syndrome (DIAPS); and establish recommendations for the improvement of DIAPS. METHODS: APS ACTION members were invited to answer a survey regarding their satisfaction with DIAPS scoring system and individual items. The level of agreement (LoA) among members with the inclusion of individual items in DIAPS was calculated (LoA of <75% was considered disagreement). Respondents' open-ended comments about DIAPS limitations were also collected, which helped formulate our recommendations for DIAPS improvement. RESULTS: Forty-two APS ACTION members (58.3%) answered the survey. Of them, 26 (61.9%) were satisfied, 4 (9.5%) were neutral, and 12 (28.6%) were dissatisfied with the current DIAPS scoring system. Fifteen items (39.5%) presented a LoA <75% regarding the inclusion in DIAPS. Respondents provided comments that were grouped under six main categories related to concerns about: a) definitions and attribution of damage (including causality and temporal relationship); b) scoring system; c) overlapping items; d) specific items (exclusion of redundant items and inclusion of additional ones); e) the need to incorporate multiple events; and f) feasibility and practicality. Finally, the APS ACTION "Damage" Working Group developed 7 recommendations that should be considered for the next generation DIAPS. CONCLUSION: Approximately 60% of respondents were satisfied with DIAPS and its definitions; however, our survey demonstrated that there is substantial room to improve the current damage index for APS. Efforts for updating DIAPS should consider the APS ACTION "Damage" Working Group recommendations.
