Exploring factors influencing time from dispatch to unit availability according to the transport decision in the pre-hospital setting: an exploratory study

BACKGROUND

Efficient resource distribution is important. Despite extensive research on response timings within ambulance services, nuances of time from unit dispatch to becoming available still need to be explored. This study aimed to identify the determinants of the duration between ambulance dispatch and readiness to respond to the next case according to the patients' transport decisions.

METHODS

Time from ambulance dispatch to availability (TDA) analysis according to the patients' transport decision (Transport versus Non-Transport) was conducted using R-Studio™ for a data set of 93,712 emergency calls managed by a Middle Eastern ambulance service from January to May 2023. Log-transformed Hazard Ratios (HR) were examined across diverse parameters. A Cox regression model was utilised to determine the influence of variables on TDA. Kaplan-Meier curves discerned potential variances in the time elapsed for both cohorts based on demographics and clinical indicators. A competing risk analysis assessed the probabilities of distinct outcomes occurring.

RESULTS

The median duration of elapsed TDA was 173 min for the transported patients and 73 min for those not transported. The HR unveiled Significant associations in various demographic variables. The Kaplan-Meier curves revealed variances in TDA across different nationalities and age categories. In the competing risk analysis, the 'Not Transported' group demonstrated a higher incidence of prolonged TDA than the 'Transported' group at specified time points.

CONCLUSIONS

Exploring TDA offers a novel perspective on ambulance services' efficiency. Though promising, the findings necessitate further exploration across diverse settings, ensuring broader applicability. Future research should consider a comprehensive range of variables to fully harness the utility of this period as a metric for healthcare excellence.

A Video-Based Study of Emergency Medical Services Handoffs to a Pediatric Emergency Department

BACKGROUND

Emergency medical services (EMS) to emergency department (ED) handoffs are important moments in patient care, but patient information is communicated inconsistently.

OBJECTIVE

The aim of this study was to describe the duration, completeness, and communication patterns of patient handoffs from EMS to pediatric ED clinicians.

METHODS

We conducted a video-based, prospective study in the resuscitation suite of an academic pediatric ED. All patients 25 years and younger transported via ground EMS from the scene were eligible. We completed a structured video review to assess frequency of transmission of handoff elements, handoff duration, and communication patterns. We compared outcomes between medical and trauma activations.

RESULTS

We included 156 of 164 eligible patient encounters from January to June 2022. Mean (SD) handoff duration was 76 (39) seconds. Chief symptom and mechanism of injury were included in 96% of handoffs. Most EMS clinicians communicated prehospital interventions (73%) and physical examination findings (85%). However, vital signs were reported for fewer than one-third of patients. EMS clinicians were more likely to communicate prehospital interventions and vital signs for medical compared with trauma activations (p < 0.05). Communication challenges between EMS clinicians and the ED were common; ED clinicians interrupted EMS or requested information already communicated by EMS in nearly one-half of handoffs.

CONCLUSIONS

EMS to pediatric ED handoffs take longer than recommended and frequently lack important patient information. ED clinicians engage in communication patterns that may hinder organized, efficient, and complete handoff. This study highlights the need for standardizing EMS handoff and ED clinician education regarding communication strategies to ensure active listening during EMS handoff.

Implementing the IMIST-AMBO tool for paramedic to trauma team handovers: a video review analysis

OBJECTIVE

Patient handover between paramedics and the trauma team is vulnerable to communication errors that may adversely affect patient care. This study assesses the feasibility of a handover tool, IMIST-AMBO (acronym of categories), implementation in the trauma bay and evaluates the degree to which it improves handover metrics.

METHODS

This is a prospective observational cohort study conducted at Canada's largest level-one trauma center. Feasibility of the tool implementation and improvement in handover metrics were assessed. Strategies for implementation included distribution of an educational video and posters, and point-of-care reminders in the trauma bay. Two reviewers independently assessed video recordings of handovers to evaluate handover metrics. Findings were compared to data obtained during a knowledge gap analysis conducted prior to the initiation of this study at the same institution.

RESULTS

Over 13 weeks (August to November 2020), 140 videos were recorded, of which 80 used the IMIST-AMBO tool (compliance of 57%). Paramedic adherence to the handover structure occurred in 70.4% of cases, with greater adherence to the IMIST (82.2%) compared to the AMBO (47.1%) section. The mean (± standard deviation) handover duration was shorter (1 min:58 s ± 0:44 s during implementation vs. 2 min:47 s ± 1:14 s pre-implementation, [p < 0.001]). Frequency of parallel conversations and informal handovers improved (61% to 30% and 65% to 13%, [p < 0.001], respectively). Interruptions during the handover decreased from 3.05 (± 1.95) to 1.5 (± 1.7), p < 0.001. The tool was received favorably among study participants.

CONCLUSION

The IMIST-AMBO tool reduced the frequency of interruptions, parallel conversations, and informal handovers during paramedic-trauma team handovers at our institution. The quality and amount of information communicated per handover improved, all with a decrease in handover duration. The IMIST-AMBO tool may be applied to other trauma centers across Canada, or more broadly on an international scale.

Pre-hospital assistance by ambulance in the context of coronavirus infections

OBJECTIVE

To reflect on the safe care exercised by the pre-hospital care team by emergency ambulance in times of coronavirus infection.

METHOD

A reflection and description of how to provide safe care to the patient and the professional during pre-hospital care in times of coronavirus infection.

RESULTS

To ensure the health of all those involved in the care, health professionals who work in pre-hospital care by emergency ambulance should use the recommended Personal Protective Equipment (PPE), such as the use of surgical masks and N95, N99, N100, PFF2 or PFF3, the use of an apron or overall, goggles and face shield, gloves and a hat. The entire team must receive training and demonstrate the ability to use PPE correctly and safely.

FINAL CONSIDERATIONS

The professional working in the pre-hospital care by ambulance is exposed to a series of occupational risks that need to be discussed and minimized through professional training.

Clinical handover from emergency medical services to the trauma team: A gap analysis

OBJECTIVES

There has been limited evaluation of handover from emergency medical services (EMS) to the trauma team. We sought to characterize these handover practices to identify areas of improvement and determine if handover standardization might be beneficial for trauma team performance.

METHODS

Data were prospectively collected over a nine-week period by a trained observer at a Canadian level one trauma centre. A randomized scheduled was used to capture a representative breadth of handovers. Data collected included outcome measures such as duration of handover, structure of the handover, and information shared, process measures such as questions and interruptions from the trauma team, and perceptions of the handover from nurses, trauma team leaders and EMS according to a bidirectional Likert scale.

RESULTS

79 formal verbal handovers were observed. Information was often missing regarding airway (present 22%), breathing (54%), medications (59%), and allergies (54%). Handover structure lacked consistency beyond the order of identification and mechanism of injury. Of all questions asked, 35% were questioning previously given information. The majority of handovers (61%) involved parallel conversations between team members while EMS was speaking. There was a statistically significant disparity between the self-evaluation of EMS handovers and the perceived quality determined by nurses and trauma team leaders.

CONCLUSIONS

We have identified the need to standardize handover due to poor information content, a lack of structure and active listening, information repetition, and discordant expectations between team members. These data will guide the development of a co-constructed framework integrating the perspectives of all team members.

Continuing Education for Prehospital Healthcare Providers in India - A Novel Course and Concept

BACKGROUND

Emergency medical services (EMS) in India face enormous challenges in providing care to a geographically expansive and diverse patient population. Over the last decade, the public-private-partnership GVK EMRI (Emergency Management and Research Institute) has trained over 100,000 emergency medical technicians (EMTs), with greater than 21,000 currently practicing, to address this critical gap in the healthcare workforce. With the rapid development and expansion of EMS, certain aspects of specialty development have lagged behind, including continuing education requirements. To date, there have been no substantial continuing education EMT skills and training efforts. We report lessons learned during development and implementation of a continuing education course (CEC) for EMTs in India.

METHODS

From 2014 to 2017, we employed an iterative process to design and launch a novel CEC focused on five core emergency competency areas (medicine and cardiology, obstetrics, trauma, pediatrics, and leadership and communication). Indian EMT instructors and providers partnered in design and content, and instructors were trained to independently deliver the CEC. Many challenges had to be overcome: scale (>21,000 EMTs), standardization (highly variable skill levels among providers and instructors), culture (educational emphasis on rote memorization rather than practical application), and translation (22 major languages and a few hundred local dialects spoken nationwide).

LESSONS LEARNED

During the assessment and development phases, we identified five key strategies for success: (1) use icon-based video instruction to ensure consistent quality and allow voice-over for easy translation; (2) incorporate workbooks during didactic videos and (3) employ low-cost simulation and case discussions to emphasize active learning; (4) focus on non-technical skills; (5) integrate a formal training-of-trainers prior to delivery of materials.

CONCLUSION

These key strategies can be combined with innovation and flexibility to address unique challenges of language, system resources, and cultural differences when developing impactful continuing educational initiatives in bourgeoning prehospital care systems in low- and middle-income countries.

Barriers to effective EMS to emergency department information transfer at patient handover: A systematic review

BACKGROUND

Handovers of care are necessary, yet a vulnerable time for patient safety. They can either reduce the risk of medical error during transitions of care or cause direct medical or financial harm to patients due to poor communication.

OBJECTIVE

To review (1) observational studies that quantify the frequency of transfer of specific data points or clinician retention of information provided in prehospital verbal handoff to assess the state of EMS-to-ED handoffs; (2) surveys and interviews of prehospital and ED staff perceptions of the handover process and any perceived barriers to optimal handover found therein; (3) interventional studies that have aimed to improve the quality of EMS to ED handoffs.

METHODS

A systematic review of the literature was performed using Pubmed, Web of Science, Google Scholar, and Cochrane Database of Systematic Reviews and by hand-searching references of relevant articles. Articles were selected that focused on verbal and/or written handover of patient care from EMS to ED providers and that addressed the above goals. Qualitative data was extracted from the articles and assessed using thematic synthesis.

RESULTS

78 articles were identified for full text review, 60 of which met inclusion criteria. Four categories of barriers emerged on thematic synthesis: educational, operational, cultural, and cognitive. Within these categories, 12 initial descriptive themes and 9 suggested interventions were identified.

CONCLUSIONS

Descriptive themes of disrespect & disinterest, environmental factors, redundancy, poor recall, conflicting goals and perspectives, technological issues, information degradation, information loss, lack of standardization, lack of training, delays, and lack of feedback were identified as barriers to effective EMS to ED handovers. Three categories of interventions were identified across the included interventional studies, namely technological, educational, and changes to cultural customs.

Is there a need for formal undergraduate patient handover training and could an educational workshop effectively provide this? A proof-of-concept study in a Scottish Medical School

BACKGROUND

Poor communication between healthcare professionals is recognised as accounting for a significant proportion of adverse patient outcomes. In the UK, the General Medical Council emphasises effective handover (handoff) as an essential outcome for medical graduates. Despite this, a significant proportion of medical schools do not teach the skill.

OBJECTIVES

This study had two aims: (1) demonstrate a need for formal handover training through assessing the pre-existing knowledge, skills and attitudes of medical students and (2) study the effectiveness of a pilot educational handover workshop on improving confidence and competence in structured handover skills.

DESIGN

Students underwent an Objective Structured Clinical Examination style handover competency assessment before and after attending a handover workshop underpinned by educational theory. Participants also completed questionnaires before and after the workshop. The tool used to measure competency was developed through a modified Delphi process.

SETTING

Medical education departments within National Health Service (NHS) Lanarkshire hospitals.

PARTICIPANTS

Forty-two undergraduate medical students rotating through their medical and surgical placements within NHS Lanarkshire enrolled in the study. Forty-one students completed all aspects.

MAIN OUTCOME MEASURES

Paired questionnaires, preworkshop and postworkshop, ascertained prior teaching and confidence in handover skills. The questionnaires also elicited the student's views on the importance of handover and the potential effects on patient safety. The assessment tool measured competency over 12 domains.

RESULTS

Eighty-three per cent of participants reported no previous handover teaching. There was a significant improvement, p<0.0001, in confidence in delivering handovers after attending the workshop. Student performance in the handover competency assessment showed a significant improvement (p<0.05) in 10 out of the 12 measured handover competency domains.

CONCLUSIONS

A simple, robust and reproducible intervention, underpinned by medical education theory, can significantly improve competence and confidence in medical handover. Further research is required to assess long-term outcomes as student's transition from undergraduate to postgraduate training.

Critcomms: a national cross-sectional questionnaire based study to investigate prehospital handover practices between ambulance clinicians and specialist prehospital teams in Scotland

BACKGROUND

Poor communication during patient handover is recognised internationally as a root cause of a significant proportion of preventable deaths. Improving the accuracy and quality of handover may reduce associated mortality and morbidity. Although the practice of handover between Ambulance and Emergency Department clinicians has received some attention over recent years there is little evidence to support handover best practice within the prehospital domain. Further research is therefore urgently required to understand the most appropriate way to deliver clinical information exchange in the pre-hospital environment. We aimed to investigate current clinical information exchange practices, perceived challenges and the preferred handover mnemonic for use during transfer of high acuity patients between ambulance clinicians and specialist prehospital teams.

METHODS

A national, cross-sectional questionnaire study. Participants were road based ambulance clinicians (RBAC) or active members of specialist prehospital teams (SPHT) based in Scotland.

RESULTS

Over a three month study period there were 247 prehospital incidents involving specialist teams. One hundred ninety individuals completed the questionnaire; 61% [n = 116] RBAC and 39% [n = 74] SPHT. Median length of prehospital experience was 10 years (IQR 5-18). Overall current prehospital handover practices were perceived as being effective (Mdn 4.00; IQR 3-4 [1 = very ineffective - 5 = very effective]) although SPHT clinicians rated handover effectiveness slightly lower than RBAC's (Mdn 3.00 vs 4.00, U = 1842.5, p = .03). 'ATMIST' (Age, Time of onset, Medical complaint/injury, Investigation, Signs and Treatment) was deemed the mnemonic of choice. The clinical variables perceived as essential for handover are not explicitly identified within the SBAR mnemonic. The most frequently reported method of recording and transferring information during handover was via memory (n = 112 and n = 120 respectively) and 'interruptions' were perceived as the most significant barrier to effective handover.

CONCLUSION

While, overall, current prehospital handover practice is perceived as effective this study has identified a number of areas for improvement. These include the development of a shared mental model through system standardisation, innovations to support information recording and delivery, and the clear identification at incidents of a handover lead. Mnemonics must be carefully selected to ensure they explicitly contain the perceived essential clinical variables required for prehospital handover; the mnemonic ATMIST meets these requirements. New theoretically informed, evidence-based interventions, must be developed and tested within existing systems of care to minimise information loss and risk to patients.
