-Patient and visitor violence adversely affects staff and organisations; however, there are few UK data about patient and visitor violence on medical wards. Therefore, we conducted a cross-sectional study using a validated tool (Survey of Violence Experienced by Staff ) in six medical wards in three North Wales district general hospitals to assess the prevalence of violence against healthcare staff. A total of 158 staff responded (12 men, 144 women, two not stated). We found that, within the previous 4 weeks, 83% of staff had experienced verbal aggression, 50% had been threatened and 63% had been physically assaulted. Of those assaulted, 56% sustained an injury, with three requiring medical assessment or treatment. Length of experience in the workplace correlated negatively with verbal abuse, but not with threats or assaults.
IntroductionHealthcare workers are one of the most likely groups to experience workplace aggression. 1 Although violence and aggression can occur in all health settings, the most extensive evidence comes from psychiatric wards. 2 The biggest single data set is the Annual National Audit of Violence conducted by the Royal College of Psychiatrists and funded by the British Healthcare Commission, whose final report was published in 2007 and contained information from 131 psychiatric wards across England and Wales. 3 In this report, 58% of nurses reported career incidents that were upsetting or distressing (n=1,809) and 72% had felt threatened or feel unsafe. In addition, 46% had been physically assaulted over the previous year. Fewer doctors and nonclinical staff reported such experiences. 3 Despite these results, a comparative international study showed that British psychiatric ward managers perceived violence and aggression to be a smaller problem on their wards compared with their Swiss and German counterparts. This was associated with the availability of control and restraint teams, regular training, clear protocols and, to a lesser degree, risk assessments, but not staffing levels. 4 Outside the psychiatric setting, the picture is less clear. Hahn et al, in a systematic review of patient and visitor violence (PVV), concluded that 'patient and visitor violence is a serious problem for healthcare staff in general hospitals, especially those working in medical and surgical units' . 5 Owing to the heterogeneity of the included studies, it was difficult to gauge a comprehensive picture of the true situation. However, the data showed patient or visitor violence was most often separated into three specific types of incident: verbal aggression, threats and physical assaults. With regards to patient violence, the percentage figures for verbal aggression ranged from 9% in a Swedish study to 97% in a Turkish study. The percentages for threats were equally variable, ranging from 5% in a Jamaican study to 70% in a US study. For physical assaults, the range was from 3% in an Israeli study to 58% in a US study. The prevalence figures for visitor aggression were generally smaller. However, one...
