Exploring individual and work organizational peculiarities of working in emergency medical communication centers in Norway- a qualitative study

Can video streaming improve first aid for injured patients? A prospective observational study from Norway

BACKGROUND

Video streaming in emergency medical communication centers (EMCC) from caller to medical dispatcher has recently been introduced in some countries. Death by trauma is a leading cause of death and injuries are a frequent reason to contact EMCC. We aimed to investigate if video streaming is associated with recognition of a need for first aid during calls regarding injured patients and improve quality of bystander first aid.

METHODS

A prospective observational study including patients from three health regions in Norway, from November 2021 to February 2023 (registered in clinical trials 10/25/2021, NCT05121649). Cases where video streaming had been used as a supplement during the medical emergency call were compared to cases where video streaming was not used during the call. Patients were included by ambulance personnel on the scene of accident if they met the following criteria: 1. Ambulance personnel arrived at a patient who had an injury, 2. One or more bystanders had been present before their arrival, 3. One or more of the following first aid measures had been performed by bystander or should have been performed: airway management, control of external bleeding, recovery position, and hypothermia prevention. Ambulance personnel assessed quality of first aid performed by bystander, and information concerning use of video streaming and patient need for first aid measures recognized by dispatcher was collected through EMCC audio logs and patient charts. We present descriptive data and results from a logistic regression analysis.

RESULTS

Data was collected on 113 cases, and dispatchers used video streaming in addition to standard telephone communication in 12/113 (10%) of the cases. The odds for the dispatcher to recognize a need for first aid during a medical emergency call were more than five times higher when video streaming was used compared to no use of video streaming (OR 5.30, 95% CI 1.11-25.44). Overall quality of bystander first aid was rated as "high". The odds ratio for the patient receiving first aid of higher quality were 1.82 (p-value 0.46) when video streaming was used by dispatcher during the call.

CONCLUSION

Our findings show that video streaming is not frequently used by dispatchers in calls regarding patients with injuries, but that video streaming is associated with improved recognition of patients' first aid needs. We found no statistically significant difference in first aid quality comparing the calls where video streaming as a supplement were used with the calls with audio only.

The MeSH heading "Call Center" is due for an update: why we recommend the more precise heading "Emergency Medical Communication Center"

Call centers can be found in various industries. However as a Medical Subject Heading (MeSH) the term "Call centers" does not reflect the critical purpose of handling emergency calls. We recommend "emergency medical communication center(s)", as this provides clarity and precision regarding the primary function and purpose of the center.

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.

Situation awareness of emergency response centre personnel during chemical incidents: an interview study in a Swedish context

OBJECTIVES

If a chemical incident occurs, the emergency response centre (ERC) personnel are the first that are notified. They need to quickly attain situation awareness, based on the information from the caller, in order to dispatch the correct emergency units. The aim of this study is to examine the situation awareness of the personnel working at ERCs-how they perceive, comprehend, project and act during chemical incidents.

METHODS

Semi-structured individual interviews with 12 participants from the Swedish ERCs were performed. The interviews were analysed with qualitative content analysis.

RESULTS

Three categories of responses were identified. Responses focused on the complexity of identifying chemical incidents, the importance of ensuring the safety of citizens and personnel of emergency organisations and the situation-based dispatch of organisations.

CONCLUSIONS

The correct identification of the chemical incident and the involved chemical by the ERC personnel are necessary in order to notify, inform and dispatch the correct units, as well as to ensure the safety of citizens and emergency personnel. More research is needed about the dichotomies of the ERC personnel needing as much information as possible for everyone's safety versus their responsibility for the safety of the caller as well as between using emergency dispatch index interview guides and trusting their gut feeling.

Emergency medical dispatchers' experiences of managing emergency calls: a qualitative interview study

OBJECTIVES

To explore the emergency medical dispatchers (EMDs) experiences of managing emergency medical calls.

DESIGN

A qualitative interview study with an inductive approach. EMDs were interviewed individually using a semistructured interview guide. The verbatim transcripts were analysed using a qualitative content analysis.

SETTING

EMDs, without a professional background as registered nurses, were recruited from emergency medical communication centers (EMCCs) within Sweden.

PARTICIPANTS

To achieve a varied description of EMDs' experiences, participants were included from several EMCCs nationally, using a convenience sampling. Interviews were performed up until saturation of data, resulting in 13 EMDs from 7 EMCCs being interviewed. All the EMDs were women, ranging in age from 28 to 61 years (mean 42 years), and had worked in emergency medical dispatching between 1 and 13.5 years (mean 6.5 years).

RESULTS

The analysis revealed the main category-to attentively manage a multifaceted, interactive task-made up of three categories: utilize creativity to gather information, continuously process and assess complex information, and engage in the professional role. The content of each category was reflected in several subcategories further described and illustrated with representative quotes.

CONCLUSIONS

Managing emergency medical calls was experienced by EMDs to attentively manage a multifaceted interactive task. Core parts were described as: the ability to utilize creativity to gather information, continuously process and asses complex information, and engage in the professional role. Our results could be beneficial for emergency care managers when designing training programmes and organising EMD work and the EMD work environment, including further development of dispatch protocols and implementation of regular feedback sessions. Moreover, the results indicate that aspects such as self-awareness and emotional challenges encountered during EMD work could be important matters to discuss during staff evaluations.

Evaluating a training intervention for improving alignment between emergency medical telephone operators and callers: a pilot study of communication behaviours

Background

Calls to emergency medical lines are an essential component in the chain of survival. Operators make critical decisions based on information they elicit from callers. Although smooth cooperation is necessary, the field lacks evidence-based guidelines for how to achieve it while adhering to strict parameters of index-driven questioning. We aimed to evaluate the effect of a training intervention for emergency medical operators at a call centre in Tønsberg, Norway. The course was designed to enhance operators’ communication skills for smoothing cooperation with callers.

Methods

Calls were analyzed using inductively developed coding based on the course rationale and content. To evaluate whether the course generated consolidated behavioral change in everyday practice, the independent analyst evaluated 32 calls, selected randomly from eight operators, two calls before and two after course completion. To measure whether skill attainment delayed decision making, we compared the time to the first decision logged by intervention operators to eight control operators. Analysis included 3034 calls: 1375 to intervention operators (T1 = 815; T2 = 560) and 1659 to control operators (T1 = 683; T2 = 976).

Results

Operators demonstrated improved behaviours on how they greeted the caller (p < .001), acknowledged the caller (p < .001), and displayed empathy (p = 0.015). No change was found in the use of open-ended questions and agreeing with the caller. Contrary to expectations, operators who took the course logged first decisions more quickly than the control group (p < .001).

Conclusions

This pilot study demonstrated that the training intervention generated behavioural change in these operators, providing justification for scaling up the intervention.

Registered nurses' understandings of emergency medical dispatch center work: A qualitative phenomenographic interview study

Non-urgent and urgent telephone nursing services are increasing globally, and phenomenographic research has shown that how work is understood may influence work performance. This descriptive study makes a qualitative inductive investigation of understandings of emergency medical dispatch center work among registered nurses. Twenty-four registered nurses at three mid Swedish emergency medical dispatch centers were interviewed. Analysis based on phenomenographic principles identified five categories in the interviews: (i) Assess, prioritize, direct, or refer; (ii) Facilitate ambulance nursing work; (iii) Perform nursing care; (iv) Always be available for the public; and (v) Have the person behind the patient in mind. The first constitutes the basis of the work. The second emphasizes cooperation with and support for the ambulance staff. The third entails remotely providing nursing care, whilst the fourth stresses serving the entire population. The fifth and most comprehensive way of understanding work involves having a holistic view of the person in need, including person-centered care. Provision of high-quality emergency medical dispatch center work involves all categories. Combined, they constitute a "work map," valuable for reflection, competence development, and introduction of new staff.
