Evaluating the correlation between the HUESAD and OSATS scores: Concurrent validity study

Background: The aim of this study was to determine whether a correlation exists between the HUESAD and both the OSATS checklist and the global rating score. Material and methods: Fourteen participants were recruited, ranging from residents to consultants. The HUESAD measured three different parameters: Visual spatial ability, smoothness and accuracy. The OSTAS measured the endoscopic surgical skills by the checklist and the global rating score. Results: A significant relationship was thus identified between the OSATS checklist (p < 0.0001), the OSATS global rating score (p < 0.05) and the HUESAD assessment in the evaluation of visual-spatial ability. In terms of smoothness, there was also a significant relationship between the OSATS checklist (p < 0.05), the OSATS global rating score (p < 0.05) and the HUESAD assessment. Moreover, there was a significant relationship between the OSATS checklist (p < 0.05), the OSATS global rating score (p < 0.05) and the HUESAD assessment for accuracy. Conclusions: There was strong correlation between the motion analysis in the HUESAD assessment and OSATS checklist and the global rating score. Moreover, the visual spatial ability, smoothness and accuracy analyzed by the HUESAD were reliable parameters when assessing the endoscopic surgical skills.
