Paramedics are increasingly being subjected to violence, creating the potential for significant physical and psychological harm. Where a patient has a history of violent behavior, hazard flags—applied either to the individual, their residential address, or phone number—can alert paramedics to the possibility of violence, potentially reducing the risk of injury. Leveraging a novel violence reporting process embedded in the electronic patient care record, we reviewed violence reports filed over a thirteen-month period since its inception in February 2021 to assess the effectiveness of hazard flagging as a potential risk mitigation strategy. Upon reviewing a report, paramedic supervisors can generate a hazard flag if recurrent violent behavior from the patient is anticipated. In all, 502 violence reports were filed, for which paramedic supervisors generated hazard flags in 20% of cases (n = 99). In general, cases were not flagged either because the incident occurred at a location not amenable to flagging or because the supervisors felt that a hazard flag was not warranted based on the details in the report. Hazard flagging was associated with an increased risk of violence during subsequent paramedic attendance (Odds Ratio [OR] 6.21, p < 0.001). Nevertheless, the process appears to reliably identify persons who may be violent towards paramedics

Violence against paramedics is widely recognized as a serious, but underreported, problem. While injurious physical attacks on paramedics are generally reported, non-physical violence is less likely to be documented. Verbal abuse can be very distressing, particularly if the harassment targets personal or cultural identities, such as race, ethnicity, gender, or sexual orientation. Leveraging a novel, point-of-event reporting process, our objective was to estimate the prevalence of harassment on identity grounds against paramedics in a single paramedic service in Ontario, Canada, and assess its potentially differential impact on emotional distress. In an analysis of 502 reports filed between 1 February 2021 and 28 February 2022, two paramedic supervisors independently coded the free-text narrative descriptions of violent encounters for themes suggestive of sexism, racism, and homophobia. We achieved high inter-rater agreement across the dimensions (k = 0.73–0.83), and after resolving discrepant cases, we found that one in four violent reports documented abuse on at least one of the identity grounds. In these cases, paramedics were 60% more likely to indicate being emotionally distressed than for other forms of violence. Our findings offer unique insight into the type of vitriol paramedics experience over the course of their work and its potential for psychological harm.

Violence against paramedics is increasingly recognized as an important occupational health problem, but pervasive and institutionalized underreporting hinders efforts at risk mitigation. Earlier research has shown that the organizational culture within paramedicine may contribute to underreporting, and researchers have recommended involving paramedics in the development of violence prevention policies, including reporting systems. Eighteen months after the launch of a new violence reporting system in Peel Region, Ontario, Canada, we surveyed paramedics about their experiences reporting violent encounters. Our objectives were to assess their willingness to report violence and explore factors that influence their decisions to file a report. Between September and December 2022, a total of 204 (33% of eligible) paramedics chose to participate, of whom 67% (N = 137) had experienced violence since the launch of the new reporting process, with 83% (N = 114) reporting the incidents at least some of the time. After thematically analyzing free-text survey responses, we found that the participants cited the accessibility of the new reporting process and the desire to promote accountability among perpetrators while contributing to a safer workplace as motivating factors. Their decisions to file a report, however, could be influenced by the perceived 'volitionality' and severity of the violent encounters, particularly in the context of (un)supportive co-workers and supervisors. Ultimately, the participants' belief that the report would lead to meaningful change within the service was a key driver of reporting behavior.

Violence against paramedics has been described as a ‘serious public health problem’ but one that remains ‘vastly underreported’, owing to an organizational culture that stigmatizes reporting–hindering efforts at risk mitigation in addition to creating a gap in research. Leveraging a novel reporting process developed after extensive stakeholder consultation and embedded within the electronic patient care record, our objective was to provide a descriptive profile of violence against paramedics in a single paramedic service in Ontario, Canada. Between 1 February 2021 and 31 January 2023, a total of 374 paramedics in Peel Region (48% of the workforce) generated 941 violence reports, of which 40% documented physical (n = 364) or sexual (n = 19) assault. The violence was typically perpetrated by patients (78%) and primarily took place at the scene of the 9-1-1 call (47%); however, violent behavior frequently persisted or recurred while in transit to hospital and after arrival. Collectively, mental health, alcohol, or drug use were listed as contributing circumstances in 83% of the violence reports. In all, 81 paramedics were physically harmed because of an assault. On average, our data correspond to a paramedic filing a violence report every 18 h, being physically assaulted every 46 h, and injured every 9 days.

Introduction Violence against paramedics has been described as a “serious public health problem”, but one that remains “vastly underreported” - in part, owing to an organizational culture that encourages paramedics to ‘brush off’ violent interactions as ‘part of the job’. A lack of reliable reporting data hinders risk mitigation strategies. Following a lengthy stakeholder engagement process, our team developed a novel reporting tool embedded within the electronic Patient Care Record (ePCR) to capture data about violent incidents. Methods Our research is situated in the Region of Peel in Ontario and uses a convergent parallel mixed methods approach, leveraging a review of External Violence Incident Reports (EVIRs) combined with user experience data from a web-based survey distributed during continuing medical education. We used descriptive statistics and logistic regression modeling to build an epidemiological profile of violence against paramedics. To identify contributing circumstances, we analyzed the free-text narratives of completed EVIRs using qualitative content analysis. Finally, we used inductive thematic analysis of survey comments to identify factors that influence paramedics’ decisions to report. Results Between February 1, 2021 through January 31, 2023, a total of 352 (45% of active-duty) paramedics filed 918 EVIRs, of which 368 (40%) documented some form of physical or sexual assault. Violent acts were most commonly perpetrated by patients (83%) and typically occurred at a scene (74%). Expert coders identified 37% of EVIRs as describing violence on the basis of gender, race, or sexual orientation. In all, 65 (8%) paramedics were injured as a result of an assault. Preliminary unadjusted analyses point to mental health (Odds Ratio [OR] 12.18), drug or alcohol intoxication (OR 10.17), or altered mental status (OR 4.22) as presenting a high risk for assault on a paramedic. Among post-deployment survey participants (33% of paramedics), 83% who had experienced violence chose to use the new reporting process - often citing a desire to protect coworkers as reasons for filing a report. Conclusion A substantial portion of the paramedic workforce is impacted by violence. Our early analysis suggests gaps in the social safety net may contribute to violent interactions during 911 service calls.

... Despite the prevalence of threats and violence in emergency care, this issue remains inadequately addressed [2,15]. The prehospital literature acknowledges the severity of this issue and hints at mitigation strategies, such as hazard flagging, training programmes and training simulations, but further research is needed to explore the mechanisms and effectiveness of these interventions [8,16,17]. There is a need to deepen our understanding of ambulance clinicians' experiences of working under such conditions. ...

... Published literature on these innovations is limited, but similar concepts can be adapted from other settings or situations. For example, recent work studying paramedics practicing in the Canadian province of Ontario found astonishing prevalence rates of violence against paramedics, largely due to functional reporting infrastructure (Mausz et al., 2023). The practical reporting process for paramedics likely increased reporting compliance, tabulating evidence of frequent violence. ...

... Paramedic cultures often present strong collegial support and a sense of belonging and are perceived as a main social support resource [3,7,18,19]. However, a culture of hardiness [7] has also been recognized within paramedic work, where traditional preconceptions of 'making it through' and 'being tough enough' are still prevalent in actions and language [3,[20][21][22]. Such implications can have potentially negative impacts on newly graduated paramedics and the manageability of their daily work, if psychological safety within the professional culture is deemed lacking [3,7,23]. ...

... One potential solution may be to "flag" individuals with a history of violent behavior such that paramedics can be alerted ahead of time if responding to a patient known to have an increased risk of violence. Our service developed a novel, point-of-event violence reporting process embedded in the electronic Patient Care Record (ePCR) [7] alongside a suite of new violence prevention policies. Paramedics are encouraged under the policy to complete a violence report immediately following the 9-1-1 call if they encounter an abusive, threatening, or assaultive person during the call. ...
