A mixed-methods study of the causes and impact of poor teamwork between junior doctors and nurses.

<bold>Objectives: </bold>This study aimed to collect and analyse examples of poor teamwork between junior doctors and nurses; identify the teamwork failures contributing to poor team function; and ascertain if particular teamwork failures are associated with higher levels of risk to patients.<bold>Design: </bold>Critical Incident Technique interviews were carried out with junior doctors and nurses.<bold>Setting: </bold>Two teaching hospitals in the Republic of Ireland.<bold>Participants: </bold>Junior doctors (n = 28) and nurses (n = 8) provided descriptions of scenarios of poor teamwork. The interviews were coded against a theoretical framework of healthcare team function by three psychologists and were also rated for risk to patients by four doctors and three nurses.<bold>Results: </bold>A total of 33 of the scenarios met the inclusion criteria for analysis. A total of 63.6% (21/33) of the scenarios were attributed to 'poor quality of collaboration', 42.4% (14/33) to 'poor leadership' and 48.5% (16/33) to a 'lack of coordination'. A total of 16 scenarios were classified as high risk and 17 scenarios were classified as medium risk. Significantly more of the high-risk scenarios were associated with a 'lack of a shared mental model' (62.5%, 10/16) and 'poor communication' (50.0%, 8/16) than the medium-risk scenarios (17.6%, 3/17 and 11.8%, 2/17, respectively).<bold>Conclusion: </bold>Poor teamwork between junior doctors and nurses is common and places patients at considerable risk. Addressing this problem requires a well-designed complex intervention to develop the team skills of doctors and nurses and foster a clinical environment in which teamwork is supported.
