How Does a Caller’s Anger, Fear and Sadness Affect Operators’ Decisions in Emergency Calls?

Identifying patients at imminent risk of out-of-hospital cardiac arrest during the Emergency Medical call: The views of call-takers

Introduction

There is little research on the triage of patients who are not yet in cardiac arrest when the emergency call is initiated, but who deteriorate and suffer a cardiac arrest during the prehospital phase of care. The aim of this study was to investigate Emergency Operation Centre staff views on ways to improve the early identification of patients who are at imminent risk of cardiac arrest, and the barriers to achieving this.

Methods

A qualitative interview and focus group study was conducted in two large Emergency Medical Services in England, United Kingdom. Twelve semi-structured interviews and one focus group were completed with Emergency Operations Centre staff. Data were analysed using reflexive thematic analysis.

Results

Three main themes were identified: The dispatch protocol and call-taker audit; Identifying and responding to deteriorating patients; Education, knowledge and skills. Barriers to recognising patients at imminent risk of cardiac arrest include a restrictive dispatch protocol, limited opportunity to monitor a patient, compliance auditing and inadequate education. Clinician support is not always optimal, and a lack of patient outcome feedback restricts dispatcher learning and development. Suggested remedies include improvements in training and education (call-takers and the public), software, clinical support and patient outcome feedback.

Conclusions

Emergency Operation Centre staff identified a multitude of ways to improve the identification of patients who are at imminent risk of out-of-hospital cardiac arrest during the Emergency Medical Service call. Suggested areas for improvement include education, triage software, clinical support redesign and patient outcome feedback.

Emotions in telephone calls to emergency medical services involving out-of-hospital cardiac arrest: A scoping review

Aims

The purpose of this scoping review was to identify and synthesise existing research evidence on emotions in the context of emergency phone calls to emergency medical services (EMS) involving out-of-hospital cardiac arrest (OHCA). The specific objectives were to identify studies that (1) described emotions during emergency OHCA calls; (2) specified an instrument or method for measuring/assessing emotions; and (3) examined the relationship between emotions and call outcomes or patient outcomes.

Methods/Data sources

Five databases were searched on 18 November 2021: Medline, Embase, PsycInfo, CINAHL, and the Cochrane Review Database. Included studies required the following three concepts to be addressed: emotions in the context of EMS calls that involved OHCA. Calls also needed to be made by a ‘second-party’ caller; and each study needed to address at least one of the three specific objectives, as outlined above.

The review was conducted in accordance with the Joanna Briggs Institute guidelines for evidence synthesis for scoping reviews.

Results

Thirteen eligible studies were included for synthesis. All studies met Objective 1; six studies met Objective 2; and seven met Objective 3. One study reported patient fatality due to heightened emotions and ensuing ineffective communications between callers and call-takers.

Conclusion

The review highlights a significant gap in the evidence base of emotions in emergency OHCA-related calls, and the need for a more comprehensive and effective method in assessing and measuring emotions in this context. Relationships between emotions (their expressions and perceptions) and call outcomes (including patient outcomes) also need more rigorous investigation.

Mediating Role of Stress at Work in the Relationship of Alexithymia and PTSD among Emergency Call Operators

Aim: The main purpose of this research was to investigate the relationship between alexithymia, stress at work, and post-traumatic stress disorder (PTSD) in impact emergency call center operators working in Poland (province of Greater Poland). The risk of exposure to critical life events was also considered. Methods: Data were collected using self-report questionnaires administered after dispatchers’ shifts. The emergency call center operators (N = 66) completed the Impact of Event Scale—Revised, 20-item Toronto Alexithymia Scale, Workplace Perceived Stress Questionnaire, and a questionnaire measuring the frequency and intensity of potentially traumatic events faced by emergency operators (a questionnaire developed by the authors). Results: Twenty of the most frequent events (e.g., child sexual harassment, rape, etc.) were identified. Results indicated that post-traumatic stress positively correlated with (a) work-related stress and (b) one aspect of alexithymia: difficulty expressing feelings. Additionally, work-related stress was identified as a mediator for the relation between alexithymia and the intensity of post-traumatic stress. Conclusions: The results of this study confirm that emergency operators are a high-risk group for the development of PTSD. The study results suggest that performing the work of an emergency dispatcher is not only demanding but also inherently involves participation in potentially traumatic events (as encountered through emergency calls).
