Teamwork The results of the focus group interviews showed that the three professional groups strived to ensure the quality of handover by cooperating within teams. The nurse anaesthetists also wanted to achieve a shared understanding of handovers between the OT team and PACU team (Paper IV). Teamwork is an essential component of achieving high reliability in healthcare organisations,31, 128 as a shared understanding and working atmosphere are factors of importance for the quality of handover.129 SBAR has been suggested to reduce the barriers that a hierarchical structure may lead to.16 However, implementation of the communication tool SBAR did not impact the teamwork climate (Paper II).
