What makes an incident critical for ambulance workers? Emotional outcomes and implications for intervention.

Abstract Ambulance workers use the term “critical incident” to refer to a category of workplace stressor. Developing an evidence-based approach to critical incident stress begins with identifying what makes incidents critical. The aim of this qualitative study was to characterize critical incidents as well as elicit suggestions for interventions. We interviewed 60 ambulance-based workers, both front-line and supervisors, and analysed interview transcripts. Having presented their suggestions for interventions more fully elsewhere (Halpern et al, 2009), here we characterize the incidents that emerged as critical and the emotional responses evoked by them. We found they suffered considerable distress from critical incidents and would welcome interventions. Incidents that were identified as critical commonly involved patient death, often combined with poignancy. These events appeared to evoke vulnerable feelings of inability to help and intense compassion, which led to further emotional, cognitive, and behavioural responses. Difficulty in acknowledging distress and fear of stigma presented significant barriers to accessing support. These barriers may be overcome by educating both ambulance personnel and their supervisors to recognize and tolerate the vulnerable feelings often evoked by critical incidents. While gender and length of service did not seem to impact on evoked emotions, recent recruits may be more open to this type of education.

Identifying risk of emotional sequelae after critical incidents

Background and purpose Ambulance workers could benefit from a method for early identification of incidents likely to result in long-term emotional sequelae. There is evidence that persistence of some measures of anxiety beyond the first week after an incident is associated with sequlae. In this study we test the hypothesis that persistence of self-identifiable components of the acute stress reaction as early as a few days post-incident is associated with sequelae. Method 228 ambulance workers volunteered to complete surveys on occurrence and persistence of physiological, behavioural and emotional responses to an index critical incident in the past, as well as symptoms of depression, post-traumatic stress, somatisation and burnout at the time of the survey. Data were analysed for associations between duration of each reaction and present symptoms. Using cut-off scores for the outcomes, we tested the RR of high scores in each of three situations: occurrence of the reaction, persistence of reaction beyond one night and persistence beyond 1 week. Results Prolonged duration of all five acute stress reaction components was associated with all four outcomes, with the strongest associations being with post-traumatic stress and depression symptoms. The occurrence of physical symptoms of arousal is an immediate predictor of long-term sequelae. Three other components—disturbed sleep, irritability and social withdrawal—provide potential indicators of long-term emotional sequelae as early as 2 days post-incident. Conclusion Four easily identifiable responses to a critical incident can potentially be used for early self-identification of risk of later emotional difficulties. These findings should be submitted to prospective testing.

Attachment Insecurity, Responses to Critical Incident Distress, and Current Emotional Symptoms in Ambulance Workers

Ambulance workers are exposed to critical incidents that may evoke intense distress and can result in long-term impairment. Individuals who can regulate distress may experience briefer post-incident distress and fewer long-term emotional difficulties. Attachment research has contributed to our understanding of individual differences in stress regulation, suggesting that secure attachment is associated with effective support-seeking and coping strategies, and fewer long-term difficulties. We tested the effect of attachment insecurity on emotional distress in ambulance workers, hypothesizing that (1) insecure attachment is associated with symptoms of current distress and (2) prolonged recovery from acute post-critical incident distress, coping strategies and supportive contact mediate this relationship. We measured (1) attachment insecurity, (2) acute distress, coping and social contact following an index critical incident and (3) current symptoms of post-traumatic stress, depression, somatization and burnout and tested the hypothesized associations. Fearful-avoidant insecure attachment was associated with all current symptoms, most strongly with depression (R=0.38, p<0.001). Fearful-avoidant attachment insecurity was also associated with maladaptive coping, reduced social support and slower recovery from social withdrawal and physical arousal following the critical incident, but these processes did not mediate the relationship between attachment insecurity and current symptoms. These findings are relevant for optimizing post-incident support for ambulance workers.

Downtime after Critical Incidents in Emergency Medical Technicians/Paramedics

Effective workplace-based interventions after critical incidents (CIs) are needed for emergency medical technicians (EMT)/paramedics. The evidence for a period out of service post-CI (downtime) is sparse; however it may prevent posttraumatic stress disorder (PTSD) and burnout symptoms. We examined the hypothesis that downtime post-CI is associated with fewer symptoms of four long-term emotional sequelae in EMT/paramedics: depression, PTSD, burnout, and stress-related emotional symptoms (accepted cut-offs defined high scores). Two hundred and one paramedics completed questionnaires concerning an index CI including downtime experience, acute distress, and current emotional symptoms. Nearly 75% received downtime; 59% found it helpful; 84% spent it with peers. Downtime was associated only with lower depression symptoms, not with other outcomes. The optimal period for downtime was between <30 minutes and end of shift, with >1 day being less effective. Planned testing of mediation of the association between downtime and depression by either calming acute post-CI distress or feeling helped by others was not performed because post-CI distress was not associated with downtime and perceived helpfulness was not associated with depression. These results suggest that outcomes of CIs follow different pathways and may require different interventions. A brief downtime is a relatively simple and effective strategy in preventing later depression symptoms.

The critical incident inventory: characteristics of incidents which affect emergency medical technicians and paramedics

BackgroundEmergency medical technicians (EMTs) and paramedics experience critical incidents which evoke distress and impaired functioning but it is unknown which aspects of incidents contribute to their impact. We sought to determine these specific characteristics by developing an inventory of critical incident characteristics and testing their relationship to protracted recovery from acute stress, and subsequent emotional symptoms.MethodsEMT/paramedics (n = 223) completed a retrospective survey of reactions to an index critical incident, and current depressive, posttraumatic and burnout symptoms. Thirty-six potential event characteristics were evaluated; 22 were associated with peritraumatic distress and were retained. We assigned inventory items to one of three domains: situational, systemic or personal characteristics. We tested the relationships between (a) endorsing any domain item and (b) outcomes of the critical incident (peritraumatic dissociation, recovery from components of the Acute Stress Reaction and depressive, posttraumatic, and burnout symptoms). Analyses were repeated for the number of items endorsed.ResultsPersonal and situational characteristics were most frequently endorsed. The personal domain had the strongest associations, particularly with peritraumatic dissociation, prolonged distressing feelings, and current posttraumatic symptoms. The situational domain was associated with peritraumatic dissociation, prolonged social withdrawal, and current posttraumatic symptoms. The systemic domain was associated with peritraumatic dissociation and prolonged irritability. Endorsing multiple characteristics was related to peritraumatic, acute stress, and current posttraumatic symptoms. Relationships with outcome variables were as strong for a 14-item inventory (situational and personal characteristics only) as the 22-item inventory.ConclusionsEmotional sequelae are associated most strongly with EMT/paramedics’ personal experience, and least with systemic characteristics. A14-item inventory identifies critical incident characteristics associated with emotional sequelae. This may be helpful in tailoring recovery support to individual provider needs.

Health of Palestinians and chronic humiliation

1206 www.thelancet.com Vol 383 April 5, 2014 police and security forces “cease using unnecessary and excessive force” against peaceful protesters. Furthermore, gender-based violence against women and girls, in the form of honour killings and domestic violence, continues to be reported in the Amnesty International annual reports on the Palestinian Authority; however, there are no such accounts in the reports on Israeli actions. Barber and colleagues do not help the Palestinians by ignoring political violence at the hands of their own governments.

Health in the occupied Palestinian territory

The use of the word “eternal” in the title of Richard Hortons piece “Occupied Palestine, an eternal alliance for health” (March 30, p 1084)1 is apt. It fits with his evangelical intentions “to put science in the service of social justice and selfdetermination.”2 However, Horton omits important data, leading to the spurious conclusion that President Obama, by disappointing the Palestinians, is failing to deliver peace or justice to them.
