Abstract: The author reviews the national and international literature on medical errors and adverse events. Contributing factors are identified, such as organisational culture, the myth of infallibility, and a one size fits all approach to health care. Conflict and communication difficulties between different health professionals is discussed in detail, as is the issue of disruptive behaviour, which includes intimidation, humiliation, undermining, domination and bullying. Some strategies for addressing these issues are proposed, such as promoting a no-blame culture, and addressing conflict between health professionals.
