Standards for Reporting of Diagnostic Accuracy using Intraoperative Neurophysiological Monitoring (STARD-IONM) Objective Intraoperative neurophysiological monitoring (IONM) plays a critical role in preserving functional integrity during surgery, yet it is challenging to compare studies due to methodological heterogeneity and inconsistent reporting. We developed the STARD-IONM extension to improve the transparency, completeness, and comparability of IONM studies. Methods The STARD-IONM initiative followed a three-phase consensus. Phase 1 convened a IONM expert panel to discuss and define the rationale and scope. Phase 2 involved structured item-level review of existing STARD items in the context of IONM, applied to published studies with iterative feedback. Phase 3 will include broader community engagement via preprints, outreach to professional societies, and public commentary. Results A systematically selected review of IONM studies revealed the underreporting of at key methodological items such as handling missing data (7%), adverse events (11%), and blinding of test and outcomes (22%). A STARD-IONM checklist with recommendations for reporting IONM studies with IONM specific examples were developed. Community feedback emphasized challenges unique to IONM, including the classification of reversible IONM changes, and variability in reference standards. Conclusions The STARD-IONM framework addresses critical gaps in the reporting of diagnostic accuracy studies involving IONM. It represents an application of the STARD criteria, wherein the original checklist has been adapted and supplemented with guidelines for IONM studies. Significance Standardized reporting will facilitate enhanced adherence to methodological standards, increase reproducibility and strengthen the evidence base for the safe and effective use of IONM, which is expected to improve clinical decision-making.
