CheckPOINT: a simple tool to measure Surgical Safety Checklist implementation fidelity
Bibliographic record
Abstract
INTRODUCTION: The WHO Surgical Safety Checklist (SSC) is a communication tool that improves teamwork and patient outcomes. SSC effectiveness is dependent on implementation fidelity. Administrative audits fail to capture most aspects of SSC implementation fidelity (ie, team communication and engagement). Existing research tools assess behaviours during checklist performance, but were not designed for routine quality assurance and improvement. We aimed to create a simple tool to assess SSC implementation fidelity, and to test its reliability using video simulations, and usability in clinical practice. METHODS: The Checklist Performance Observation for Improvement (CheckPOINT) tool underwent two rounds of face validity testing with surgical safety experts, clinicians and quality improvement specialists. Four categories were developed: checklist adherence, communication effectiveness, attitude and engagement. We created a 90 min training programme, and four trained raters independently scored 37 video simulations using the tool. We calculated intraclass correlation coefficients (ICC) to assess inter-rater reliability (ICC>0.75 indicating excellent reliability). We then trained two observers, who tested the tool in the operating room. We interviewed the observers to determine tool usability. RESULTS: The CheckPOINT tool had excellent inter-rater reliability across SSC phases. The ICC was 0.83 (95% CI 0.67 to 0.98) for the sign-in, 0.77 (95% CI 0.63 to 0.92) for the time-out and 0.79 (95% CI 0.59 to 0.99) for the sign-out. During field testing, observers reported CheckPOINT was easy to use. In 98 operating room observations, the total median (IQR) score was 25 (23-28), checklist adherence was 7 (6-7), communication effectiveness was 6 (6-7), attitude was 6 (6-7) and engagement was 6 (5-7). CONCLUSIONS: CheckPOINT is a simple and reliable tool to assess SSC implementation fidelity and identify areas of focus for improvement efforts. Although CheckPOINT would benefit from further testing, it offers a low-resource alternative to existing research tools and captures elements of adherence and team behaviours.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
