The development and measurement properties of the trauma NOn-TECHnical skills (T-NOTECHS) scale: A scoping review

Purpose: Conduct a scoping review to critically appraise the development and summarize the evidence on the measurement properties of T-NOTECHS including sensibility, reliability, and validity.

Methods: A literature search was performed using Pubmed and Ovid databases. Studies that described the development process of T-NOTECHS and primary studies that presented evidence of reliability and validity were identified and included. Measurement properties of T-NOTECHS was assessed and summarized under the following: scale development, sensibility, reliability, and validity.

Results: The literature search yielded 245 articles with 24 studies meeting inclusion criteria. The T-NOTECHS was developed with an acceptable robust methodology. It has good sensibility with adequate content, face validity, and feasibility. It is a reliable measure of non-technical skills in the setting of trauma video review, which improves with expert raters or extensive training. The T-NOTECHS is a valid discriminative and evaluative instrument that measures non-technical skills of multidisciplinary trauma teams.

Conclusions: T-NOTECHS provides reliable and valid measurements of non-technical skills of trauma teams, particularly when assessing trauma video review and non-technical skills training interventions by expert raters.
