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. 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. 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. 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. •T-NOTECHS was developed with an acceptable robust methodology.•The tool has good sensibility with adequate content, face validity, & feasibility.•Synthesis of evidence supports T-NOTECHS′ use as a discriminative & evaluative tool.•Ideal rater has clinical expertise in trauma care & simulation-based teaching.•Ideal setting to utilize T-NOTECHS is with trauma video review.

A modified nontechnical skills (NOTECHS) scale for trauma (T-NOTECHS) was developed to teach and assess teamwork skills of multidisciplinary trauma resuscitation teams. In this study, T-NOTECHS was evaluated for reliability and correlation with clinical performance. Interrater reliability (intraclass correlation coefficient) and correlation with the speed and completeness of resuscitation tasks were assessed during simulation-based teamwork training and during actual trauma resuscitations. For T-NOTECHS ratings done in real time, intraclass correlation coefficients were .44 for simulated and .48 for actual resuscitations. Reliability was higher (intraclass correlation coefficient = .71) for video review of resuscitations. Better T-NOTECHS scores were correlated with better performance during simulations, evidenced by a greater number of completed resuscitation tasks ( r = .50, P < .01) and faster time to completion ( r = −.38, P < .05) In actual resuscitations, T-NOTECHS ratings improved after teamwork training ( P < .001). Higher T-NOTECHS scores were correlated with better clinical performance, evidenced by faster resuscitation ( r = −.13, P < .05) and fewer unreported resuscitation tasks ( r = −.16, P < .05). Improvement in T-NOTECHS scores after teamwork training, and correlation with clinical parameters in simulated and actual trauma resuscitations, suggest its clinical relevance. Further evaluation, aiming to improve reliability, may be warranted.

Recent developments in the surgical literature highlight the need for assessment of nontechnical skills in surgery. We report a revision of the NOn-TECHnical Skills (NOTECHS) scale of the aviation industry for use in surgery and detailed analysis on its reliability. The original NOTECHS scale assesses (1) Cooperation, (2) Leadership and Managerial Skills, (3) Situation Awareness and Vigilance, and (4) Decision Making. We added a Communication and Interaction dimension and adapted all subscales for use in surgical context. Reliability was assessed in simulation-based training for trainee clinicians. Satisfactory reliability (Cronbach's α) was obtained (1) across professional groups and trainers and trainees, (2) in separate analyses for trainers and trainees, (3) in successive administrations of the scale, and (4) in surgical, anaesthetic and nursing groups analyzed separately. In the operating department practitioners group, Situation Awareness and Vigilance and Cooperation and Team Skills exhibited lower reliability. Assessment of surgical nontechnical skills is becoming a training priority. The present evidence suggests that the revised NOTECHS scale exhibits good reliability. Further empirical research should assess the validity of the scale.

Background and importance Use of video review in medicine is established in contexts such as surgery. Although not widely used in the emergency department (ED), some centres use it to evaluate non-technical skills (NTS) to support teaching and quality improvement. Objective There is no consensus on assessment of NTS using video review in the ED and the purpose of this review was to identify tools used in this context. Design, setting and participants Studies were identified using Embase, Medline, CINAHL and Google Scholar. Inclusion criterion for the review was NTS of resuscitation teams working within the ED were assessed using video review. A systematic search method was used, and results were synthesised after search criteria was checked by two independent reviewers. Authors settled on the same 9 studies eligible for inclusion. Outcome measures and analysis Reliability and validity of tools identified for use in this context. Due to the heterogeneity of studies, no meta-analysis occurred. Main results There are 9 studies included in the review. The review was registered with PROSPERO (Ref No: CRD42022306129). Four unique tools were identified – 6 studies used T-NOTECHS, 1 used TTCA-24, 1 used CALM and 1 used the Communication tool. T-NOTECHS is validated in the literature for use in this context. Conclusion T-NOTECHS is the tool of choice for assessing ED teams in this context.

PurposeNon-technical skills have gained attention, since enhancement of these skills is presumed to improve the process of trauma resuscitation. However, the reliability of assessing non-technical skills is underexposed, especially when using video analysis. Therefore, our primary aim was to assess the reliability of the Trauma Non-Technical Skills (T-NOTECHS) tool by video analysis. Secondarily, we investigated to what extent reliability increased when the T-NOTECHS was assessed by three assessors [average intra-class correlation (ICC)] instead of one (individual ICC).MethodsAs calculated by a pre-study power analysis, 18 videos were reviewed by three research assistants using the T-NOTECHS tool. Average and individual degree of agreement of the assessors was calculated using a two-way mixed model ICC.ResultsAverage ICC was ‘excellent’ for the overall score and all five domains. Individual ICC was classified as ‘excellent’ for the overall score. Of the five domains, only one was classified as ‘excellent’, two as ‘good’ and two were even only ‘fair’.ConclusionsAssessment of non-technical skills using the T-NOTECHS is reliable using video analysis and has an excellent reliability for the overall T-NOTECHS score. Assessment by three raters further improve the reliability, resulting in an excellent reliability for all individual domains.

BackgroundCommunication and teamwork failures have frequently been identified as the root cause of adverse events and complications in surgery. Few studies have examined contextual factors that influence teams’ non-technical skills (NTS) in surgery. The purpose of this prospective study was to identify and describe correlates of NTS.MethodsWe assessed NTS of teams and professional role at 2 hospitals using the revised 23-item Non-TECHnical Skills (NOTECHS) and its subscales (communication, situational awareness, team skills, leadership and decision-making). Over 6 months, 2 trained observers evaluated teams’ NTS using a structured form. Interobserver agreement across hospitals ranged from 86% to 95%. Multiple regression models were developed to describe associations between operative time, team membership, miscommunications, interruptions, and total NOTECHS and subscale scores.ResultsWe observed 161 surgical procedures across 8 teams. The total amount of explained variance in NOTECHS and its 5 subscales ranged from 14% (adjusted R2 0.12, p<0.001) to 24% (adjusted R2 0.22, p<0.001). In all models, inverse relationships between the total number of miscommunications and total number of interruptions and teams’ NTS were observed.ConclusionsMiscommunications and interruptions impact on team NTS performance.

Background The 5-item non-technical skills scale for trauma (T-NOTECHS) with five response categories is developed to assess non-technical skills in trauma team resuscitations. This validated instrument assesses behavioral aspects in teamwork. Outcome instruments should undergo a robust adaptation process followed by psychometric validation to maintain their measurement properties when translated into different languages. The translatability of the T-NOTECHS into a non-Anglo-Saxon language has not been thus far unraveled. The authors aimed to assess whether the T-NOTECHS would be translatable into a non-Anglo-Saxon language and to investigate its psychometric properties for simulated multi-professional trauma team resuscitations. Methods The T-NOTECHS (scores: 1 = poor; 5 = excellent) was translated and cross-culturally adapted into Finnish. Data was derived from 61 real hospital trauma team resuscitation simulations with 193 multi-professional participants. Floor-ceiling effects, internal consistency, and inter-rater reliability were analyzed. An exploratory factor analysis was conducted to test construct validity. Results After pre-testing, minor changes were made to the Finnish translation of the T-NOTECHS. Mean scores of two raters were 3.76 and 4.01, respectively. The T-NOTECHS instrument showed no floor-effect either in single items or in the total score. The total score of the T-NOTECHS instrument showed a percentage of maximum scores of 1.6 and 4.9% by the Raters 1 and 2, respectively. Internal consistency (Cronbach’s alpha) was 0.70 with inter-item correlation of 0.54. The intraclass correlation coefficient was 0.54 and coefficient of repeatability 1.53. The T-NOTECHS loaded on one factor. Conclusions The T-NOTECHS translated well into a difficult non-Anglo-Saxon language. The rigorous adaptation process used here can be recommended in the translation of observational performance assessment instruments. The translated version demonstrated fair reliability and good construct validity for assessing team performance in simulated multi-professional trauma team resuscitations. The translated T-NOTECHS instrument can be used to assess the efficacy of simulated in-situ trauma team resuscitations allowing benchmarking and international collaboration.

Trauma care requires coordinating an interprofessional team, with formative feedback on teamwork skills. We hypothesized nurses and surgeons have different perceptions regarding roles during resuscitation; that nurses' teamwork self-assessment differs from experts', and that video debriefing might improve accuracy of self-assessment. Trauma nurses and surgeons were surveyed regarding resuscitation responsibilities. Subsequently, nurses joined interprofessional teams in simulated trauma resuscitations. After each resuscitation, nurses and teamwork experts independently scored teamwork (T-NOTECHS). After video debriefing, nurses repeated T-NOTECHS self-assessment. Nurses and surgeons assumed significantly more responsibility by their own profession for 71% of resuscitation tasks. Nurses' overall T-NOTECHS ratings were slightly higher than experts'. This was evident in all T-NOTECHS subdomains except “leadership,” but despite statistical significance the difference was small and clinically irrelevant. Video debriefing did not improve the accuracy of self-assessment. Nurses and physicians demonstrated discordant perceptions of responsibilities. Nurses' self-assessment of teamwork was statistically, but not clinically significantly, higher than experts' in all domains except physician leadership.

The influence of atmospheric corrosion inhibitors NOTECh, N-M-1, and FMT and phosphating primer VL-02 on the electrochemical properties of anticorrosion coatings based on a new modification of OS-51-03M organosilicate composition is considered. For corrosion tests using the method of potentiodynamic polarization, plates made of carbon steel grade St3sp5 were used, on which coatings were applied by the paint and varnish method. It was found that the NOTECh aqueous phosphating composition and the N‑M-1 corrosion inhibitor significantly increase the corrosion resistance of organosilicate coatings in an aggressive environment—3% NaCl solution. For these coatings, it is impossible to register the current and corrosion potential after 1 month of exposure of the coatings in a corrosive environment. Under similar measurement conditions, the electrochemical parameters of steel plates with an unmodified organosilicate coating were determined: the corrosion current density is 8 × 10–9 A/m2; the corrosion potential is –144 mV. It was found that the VL-02 phosphating primer has little effect on increasing the duration of anticorrosive protection of the organosilicate coating system. The type of inhibitory protection of atmospheric corrosion inhibitors is determined.

Das Buch „To err is human“ 1999 begann, das Risikomanagement in der Medizin für immer zu verändern. Nach der „Harvard Medical Practice Study“ 1991, der ersten großen Publikation, in der alle wesentlichen Aspekte vermeidbaren Schadens in der Medizin beschrieben wurden, rückten vermeidbare Fehler zunehmend in den Fokus. Auch in der medizinischen Welt ist heute weitgehend akzeptiert, dass der menschliche Fehler, hervorgerufen durch entsprechende Rahmenbedingungen, zu 70% die Hauptursache aller Unfälle darstellt. Helmreich, Luftfahrtpsychologe und Pionier in Sachen Fehlermanagement, schrieb: „Fehler sind die Folge der Überschreitung physiologischer und psychologischer Leistungsgrenzen der Menschen. Fehlerursachen umfassen Müdigkeit, Arbeitslast und Angst, genauso wie Informationsüberflutung, schlechte Kommunikation, ungenügende Informationsverarbeitung und falsche Entscheidungsfindung.“ Effektives Fehlermanagement basiert auf dem Verständnis der Entstehung menschlicher Fehler. Leider lösen Fehlerfolgen noch immer Reaktionen aus, die sich gegen Einzelne richtet (Sündenbockkultur). Ärzte/Pflegepersonal am Ende der Fehlerkette werden häufig als Schuldige hingestellt. Während medizinische Fähigkeiten weiterhin die unbedingte Basis für den klinischen Erfolg darstellen, sind es die NOTECHS (nicht technischen Fähigkeiten), die helfen, Katastrophen, die auf den „menschlichen Faktor“ zurückzuführen sind, zu verhindern. Dargestellt werden die wirksamsten Strategien zum Risikomanagement. Sie müssen implementiert und mit dem Kreissaalpersonal trainiert werden, wenn Schaden am Patienten nachhaltig und wirksam reduziert werden soll.
