Team climate
Scores per dimension were generated in percentages, with a higher value
representing greater team climate (range, 0–100%). Scores per
subdimension depended on the number of questions related to that
specific subdimension. If, for example, the subdimension entailed three
questions, the maximum score for that subdimension was 3 × 5 (5-point
Likert scale) = 15 points. The score was then calculated as: first
dimension score/15 × 100%. The dimension score is the mean of all
according subdimension scores. The overall TCI score comprises the mean
scores of all four dimensions. A linear mixed model was used to measure
changes in the TCI scores in 2016 and 2019 compared with 2014
(baseline). We adjusted for clustering of surgical teams. If this model
provided no fit of the data, we omitted the random effect for teams. A
p-value of ≤0.05 was regarded as statistically significant. The
statistical software IBM SPSS V.25 was used for all statistical analyses
and data processing.
