The STROCSS 2024 guideline: strengthening the reporting of cohort, cross-sectional, and case-control studies in surgery

Abstract

INTRODUCTION: First released in 2017, the STROCSS guidelines have become integral for promoting high-quality reporting of observational research in surgery. However, regular updates are essential to ensure they remain relevant and of value to surgeons. Building on the 2021 updates, the authors have developed the STROCSS 2024 guidelines. This timely revision aims to address residual reporting gaps, assimilate recent advances, and further strengthen observational study quality across all surgical disciplines. METHODS: A core steering committee compiled proposed changes to update the STROCSS 2021 guidelines based on identified gaps in prior iterations. An expert panel of surgical research leaders then evaluated the proposed changes for inclusion. A Delphi consensus exercise was used. Proposals that scored between 7-9 on a nine-point Likert agreement scale, by ≥70% of Delphi participants, were integrated into the STROCSS 2024 checklist. RESULTS: In total, 46 of 56 invited participants (82%) completed the Delphi survey and hence participated in the development of STROCSS 2024. All suggested amendments met the criteria for inclusion, indicating a high level of agreement among the Delphi group. All proposed items were therefore integrated into the final revised checklist. CONCLUSION: The authors present the updated STROCSS 2024 guidelines, which have been developed through expert consensus to further enhance the transparency and reporting quality of observational research in surgery.
