Occupational specific factors of improvement after implementation of name tagging in the OR. Columns are illustrated in accordance with the occupational specific colour of the name tags (except for ‘others’). Appreciation (a) did not change significantly between the professional groups. Although, the atmosphere in the OR was enhanced for ‘OR nurses’ compared to ‘anaesthetic nurses’ (b). Communication shows significant amelioration on part of the surgical department (c) whereas the delegation of tasks does not seem to differ between professional fields (d). ns = not significant, *P < 0.05; Fisher's exact test
