Correlates of non-technical skills in surgery: a prospective study

Communication 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.

We 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.

We 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.

Miscommunications and interruptions impact on team NTS performance.
