ObjectiveTo explore incidents of bullying and undermining among obstetrics and gynaecology (O&G) consultants in the UK, to add another dimension to previous research and assist in providing a more holistic understanding of the problem in medicine.DesignQuestionnaire survey.SettingRoyal College of Obstetricians and Gynaecologists (RCOG).ParticipantsO&G consultant members/fellows of the RCOG working in the UK.Main outcome measuresMeasures included a typology of 4 bullying and undermining consequences from major to coping.ResultsThere was a 28% (664) response rate of whom 44% (229) responded that they had been persistently bullied or undermined. Victims responded that bullying and undermining is carried out by those senior or at least close in the hierarchy. Of the 278 consultants who answered the question on ‘frequency of occurrence’, 50% stated that bullying and undermining occurs on half, or more, of all encounters with perpetrators and two-thirds reported that it had lasted more than 3 years. The reported impact on professional and personal life spans a wide spectrum from suicidal ideation, depression and sleep disturbance, and a loss of confidence. Over half reported problems that could compromise patient care. When victims were asked if the problem was being addressed, 73% of those that responded stated that it was not.ConclusionsSignificant numbers of consultants in O&G in the UK are victims of bullying and undermining behaviour that puts their own health and patient care at risk. New interventions to tackle the problem, rather than its consequences, are required urgently, together with greater commitment to supporting such interventions.
