National Assessment of Quality Programs in Emergency Medical Services

Setting an agenda for a national pediatric trauma system: Operationalization of the Pediatric Trauma State Assessment Score

ABSTRACT

Pediatric trauma system development is essential to public health infrastructure and pediatric health systems. Currently, trauma systems are managed at the state level, with significant variation in consideration of pediatric needs. A recently developed Pediatric Trauma System Assessment Score (PTSAS) demonstrated that states with lower PTSAS have increased pediatric mortality from trauma. Critical gaps are identified within six PTSAS domains: Legislation and Funding, Access to Care, Injury Prevention and Recognition, Disaster, Quality Improvement and Trauma Registry, and Pediatric Readiness. For each gap, a recommendation is provided regarding the necessary steps to address these challenges. Existing national organizations, including governmental, professional, and advocacy, highlight the potential partnerships that could be fostered to support efforts to address existing gaps. The organizations created under the US administration are described to highlight the ongoing efforts to support the development of pediatric emergency health systems.It is no longer sufficient to describe the disparities in pediatric trauma outcomes without taking action to ensure that the health system is equipped to manage injured children. By capitalizing on organizations that intersect with trauma and emergency systems to address known gaps, we can reduce the impact of injury on all children across the United States.

A National Assessment of EMS Performance at the Response and Agency Level

BACKGROUND

In 2019, the National EMS Quality Alliance (NEMSQA) established a suite of 11 evidence-based EMS quality measures, yet little is known regarding EMS performance on a national level. Our objective was to describe EMS performance at a response and agency level using the National EMS Information System (NEMSIS) dataset.

METHODS

The 2019 NEMSIS research dataset of all EMS 9-1-1 responses in the United States was utilized to calculate 10 of 11 NEMSQA quality measures. Measure criteria and pseudocode was implemented to calculate the proportion meeting measure criteria and 95% confidence intervals across all encounters and for each anonymized agency. We omitted Pediatrics-03b because the NEMSIS national dataset does not report patient weight. Agency level analysis was subsequently stratified by call volume and urbanicity.

RESULTS

Records from 9,679 agencies responding to 26,502,968 9-1-1 events were analyzed. Run-level average performance ranged from 12% for Safety-01 (encounter documented as initial response without the use of lights and siren to 82% for Pediatrics-02 (documented respiratory assessment in pediatric patients with respiratory distress) At the agency level, significant variation in measure performance existed by agency size and by urbanicity. At the individual agency performance analysis, Trauma-04 (trauma patients transported to trauma center) had the lowest agency-level performance with 47% of agencies reporting 0% of eligible runs with documented transport to a trauma center.

CONCLUSION

There is a wide range of performance in key EMS quality measures across the United States that demonstrate a need to identify strategies to improve quality and equity of care in the prehospital environment, system performance and data collection.

Emergency Medical Services Compliance With Prehospital Stroke Quality Metrics Is Associated With Faster Stroke Evaluation and Treatment

BACKGROUND

Emergency medical services (EMS) is an important link in the stroke chain of recovery. Various prehospital quality metrics have been proposed for prehospital stroke care, but their individual impact is uncertain. We sought to measure associations between EMS quality metrics and downstream stroke care.

METHODS

This is a retrospective analysis of a cohort of EMS-transported stroke patients assembled through a linkage between Michigan's EMS and stroke registries. We used multivariable regression to quantify the independent associations between EMS quality metric compliance (dispatch within 90 seconds of 911 call, prehospital stroke screen documentation [Prehospital stroke scale], glucose check, last known well time, maintenance of scene times ≤15 minutes, hospital prenotification, and intravenous line placement) and shorter door-to-CT times (door-to-CT ≤25), accounting for EMS recognition, age, sex, race, stroke subtype, severity, and duration of symptoms. We then developed a simple EMS quality score based on metrics associated with early CT and examined its associations with hospital stroke evaluation times, treatment, and patient outcomes.

RESULTS

Five thousand seven hundred seven EMS-transported stroke cases were linked to prehospital records from January 2018 through June 2019. In multivariable analysis, prehospital stroke scale documentation (adjusted odds ratio, 1.4 [1.2-1.6]), glucose check (1.3 [1.1-1.6]), on-scene time ≤15 minutes (1.6 [1.4-1.9]), hospital prenotification ([2.0 [1.4-2.9]), and intravenous line placement (1.8 [1.5-2.1]) were independently associated with a door-to-CT ≤25 minutes. A 5-point quality score (1 point for each element) was therefore developed. In multivariable analysis, a 1-point higher EMS quality score was associated with a shorter time from EMS contact to CT (-9.2 [-10.6 to -7.8] minutes; P<0.001) and thrombolysis (-4.3 [-6.4 to -2.2] minutes; P<0.001), and higher odds of discharge to home (adjusted odds ratio, 1.1 [1.0-1.2]; P=0.002).

CONCLUSIONS

Five EMS actions recommended by national guidelines were associated with rapid CT imaging. A simple quality score derived from these measures was also associated with faster stroke evaluation, greater odds of reperfusion treatment, and discharge to home.

Barriers and facilitators for developing a prehospital emergency care system evaluation tool (PEC-SET) for low-resource settings: a qualitative analysis

OBJECTIVES

Strengthening of emergency care systems, including prehospital systems, can reduce death and disability. We aimed to identify perspectives on barriers and facilitators relating to the development and implementation of a prehospital emergency care system assessment tool (PEC-SET) from prehospital providers representing several South and Southeast (SE) Asian countries.

DESIGN

We conducted a qualitative study using focus group discussions (FGD) informed by the Consolidated Framework for Implementation Research (CFIR). FGDs were conducted in English, audioconferencing/videoconferencing was recorded, transcribed verbatim and coded using an inductive and deductive approach. Participants suggested specific elements to be measured within three main 'pillars' of disease conditions proposed by the research team of the tool being developed (cardiovascular, trauma and perinatal emergencies).

SETTING

We explored the perspectives of medical directors in six low-income and middle-income countries (LMICs) in South and SE Asia.

PARTICIPANTS

A total of 16 participants were interviewed (1 Vietnam, 4 Philippines, 4 Thailand, 5 Malaysia, 1 Indonesia and 1 Pakistan) as a part of 4 focus groups.

RESULTS

Themes identified within the four CFIR constructs included: (1) Intervention characteristics: importance of developing an contextually specific tool, need for generalisability, trialling in one geographical area or with one pillar before expanding; (2) Inner setting: data transfer barriers, workforce shortages; (3) Outer setting: underdevelopment of EMS nationally; need for further EMS system development prior to implementing a tool and (4) Individual characteristics: lack of buy-in by prehospital personnel. Elements proposed by participants included both process and outcome measures.

CONCLUSIONS

Through the CFIR framework, we identified several themes which can provide a basis for codeveloping a PEC-SET for LMICs with local stakeholders. This work may inform development of quality improvement tools in LMIC PEC systems.

How do current police practices impact trauma care in the prehospital setting? A scoping review

Objective

In the United States, police are often important co-responders to 911 calls with emergency medical services for medical emergencies. To date, there remains a lack of a comprehensive understanding of the mechanisms by which police response modifies time to in-hospital medical care for traumatically injured patients. Further, it remains unclear if differentials exist within or between communities. A scoping review was performed to identify studies evaluating prehospital transport of traumatically injured patients and the role or impact of police involvement.

Methods

PubMed, SCOPUS, and Criminal Justice Abstracts databases were utilized to identify articles. English-language, US-based, peer-reviewed articles published on or prior to March 30, 2022 were eligible for inclusion.

Results

Of 19,437 articles initially identified, 70 articles were selected for full review and 17 for final inclusion. Key findings included (1) current law enforcement practices involving scene clearance introduce the potential for delayed patient transport but to date there is little research quantifying delays; (2) police transport protocols may decrease transport times; and (3) there are no studies examining the potential impact of scene clearance practices at the patient or community level.

Conclusions

Our results highlight that police are often the first on scene when responding to traumatic injuries and have an active role via scene clearance or, in some systems, patient transport. Despite the significant potential for impact on patient well-being, there remains a paucity of data examining and driving current practices.

Regionalization of EMS Medical Direction for Naval Medical Forces Pacific

INTRODUCTION

Medical direction has been the cornerstone to safe and effective prehospital and enroute care since the establishment of emergency medical services (EMS). Medical oversight by a physician has been shown to improve clinical outcomes in both settings. When the Navy Regional Office of the EMS Medical Director was established in 2016, it brought additional resources, including the addition of a paramedic and nurse EMS analyst and recruitment of additional local medical directors (LMDs). This, combined with the engagement of military leadership, allowed for expansion and improvement of medical direction in our prehospital and enroute care system and the establishment of a continuous quality improvement (CQI) program.

MATERIALS AND METHODS

In 2017, a database was created to collect total run volume, acuity of calls, number of certain time-sensitive conditions, and CQI performance. A retrospective review of this database was conducted. This project was deemed institutional review board exempt.

RESULTS

LMD reports that submission went from 17% for 2017 to 64% for 2018, 91% for 2019, and 79% for 2020. In 2019, 67% of the sites had verifiable CQI programs and, in 2020, this improved to 80% of sites. The review also revealed insight into levels of acuity seen by prehospital and enroute care providers.

CONCLUSION

Our results demonstrate that improvement in medical oversight in a large regional prehospital system can be achieved through persistence and engagement of nonmedical leadership.

Peripheral intravenous catheter and intraosseous device insertions reported from the 1st July 2016 to 30th June 2017 in an Australian state ambulance service: An observational study

OBJECTIVE

To overcome the lack of larger, population-based studies reporting the prevalence of insertion of PIVCs and IO devices, and to describe the patient-related and service-related characteristics of these devices, inserted by paramedics, in an Australian state ambulance service.

METHODS

A retrospective analysis of the electronic Ambulance Report Form (medical record) and Computer Aided Dispatch system from the 1st July 2016 until 30th June 2017.

RESULTS

709,217 events were analysed. Of these, 20.4% involved at least one successful PIVC insertion and 0.07% involved at least one successful IO device insertion; most of the time on first attempt (89% and 86.4% respectively). Most PIVCs were inserted into the right antecubital fossa or dorsum of the right hand while IO devices were inserted into the proximal tibia. Of male patients, 21.4% received PIVCs while 19.5% of female patients received PIVCs. Very low numbers of both male and female patients received IOs (0.1%). Medical, non-traumatic presentations were the most common presentation and received the most insertions of both devices, followed by trauma presentations. Advanced Care Paramedics inserted 84.0% of PIVCs while Critical Care Paramedics inserted 94.4% of IO devices. Time treating and transporting patients generally increased with number of attempts at vascular access undertaken.

CONCLUSIONS

Queensland paramedic practices relating to insertion of PIVCs, and IO devices appears consistent with documented practice internationally. Further study is required to determine whether the antecubital fossa and dorsum of the hand insertions are clinically necessary in this population as areas of flexion and distal extremities are generally to be avoided for PIVC insertion.

Quality Management of Prehospital Airway Programs: An NAEMSP Position Statement and Resource Document

Prehospital airway management encompasses a multitude of complex decision-making processes, techniques, and interventions. Quality management (encompassing quality assurance and quality improvement activities) in EMS is dynamic, evidence-based, and most of all, patient-centric. Long a mainstay of the EMS clinician skillset, airway management deserves specific focus and attention and dedicated quality management processes to ensure the delivery of high-quality clinical care.It is the position of NAEMSP that:All EMS agencies should dedicate sufficient resources to patient-centric, comprehensive prehospital airway quality management program. These quality management programs should consist of prospective, concurrent, and retrospective activities. Quality management programs should be developed and operated with the close involvement of the medical director.Quality improvement and quality assurance efforts should operate in an educational, non-disciplinary, non-punitive, evidence-based medicine culture focused on patient safety. The highest quality of care is only achieved when the quality management program rewards those who identify and seek to prevent errors before they occur.Information evaluated in prehospital airway quality management programs should include both subjective and objective data elements with uniform reporting and operational definitions.EMS systems should regularly measure and report process, outcome, and balancing airway management measures.Quality management activities require large-scale bidirectional information sharing between EMS agencies and receiving facilities. Hospital outcome information should be shared with agencies and the involved EMS clinicians.Findings from quality management programs should be used to guide and develop initial education and continued training.Quality improvement programs must continually undergo evaluation and assessment to identify strengths and shortcomings with a focus on continuous improvement.

Novel Technologies and Techniques for Prehospital Airway Management: An NAEMSP Position Statement and Resource Document

Novel technologies and techniques can influence airway management execution as well as procedural and clinical outcomes. While conventional wisdom underscores the need for rigorous scientific data as a foundation before implementation, high-quality supporting evidence is frequently not available for the prehospital setting. Therefore, implementation decisions are often based upon preliminary or evolving data, or pragmatic information from clinical use. When considering novel technologies and techniques. NAEMSP recommends:Prior to implementing a novel technology or technique, a thorough assessment using the best available scientific data should be conducted on the technical details of the novel approach, as well as the potential effects on operations and outcomes.The decision and degree of effort to adopt, implement, and monitor a novel technology or technique in the prehospital setting will vary by the quality of the best available scientific and clinical information:• Routine use - Technologies and techniques with ample observational but limited or no interventional clinical trial data, or with strong supporting in-hospital data. These techniques may be reasonably adopted in the prehospital setting. This includes video laryngoscopy and bougie-assisted intubation. • Limited use - Technologies and techniques with ample pragmatic clinical use information but limited supporting scientific data. These techniques may be considered in the prehospital setting. This includes suction-assisted laryngoscopy and airway decontamination and cognitive aids. • Rare use - Technologies and techniques with minimal clinical use information. Use of these techniques should be limited in the prehospital setting until evidence exists from more stable clinical environments. This includes intubation boxes.The use of novel technologies and techniques must be accompanied by systematic collection and assessment of data for the purposes of quality improvement, including linkages to patient clinical outcomes.EMS leaders should clearly identify the pathways needed to generate high-quality supporting scientific evidence for novel technologies and techniques.

Understanding quality systems in the South African prehospital emergency medical services: a multiple exploratory case study

Introduction

In South Africa (SA), prehospital emergency care is delivered by emergency medical services (EMS) across the country. Within these services, quality systems are in their infancy, and issues regarding transparency, reliability and contextual relevance have been cited as common concerns, exacerbated by poor communication, and ineffective leadership. As a result, we undertook a study to assess the current state of quality systems in EMS in SA, so as to determine priorities for initial focus regarding their development.

Methods

A multiple exploratory case study design was used that employed the Institute for Healthcare Improvement’s 18-point Quality Program Assessment Tool as both a formative assessment and semistructured interview guide using four provincial government EMS and one national private service.

Results

Services generally scored higher for structure and planning. Measurement and improvement were found to be more dependent on utilisation and perceived mandate. There was a relatively strong focus on clinical quality assessment within the private service, whereas in the provincial systems, measures were exclusively restricted to call times with little focus on clinical care. Staff engagement and programme evaluation were generally among the lowest scores. A multitude of contextual factors were identified that affected the effectiveness of quality systems, centred around leadership, vision and mission, and quality system infrastructure and capacity, guided by the need for comprehensive yet pragmatic strategic policies and standards.

Conclusion

Understanding and accounting for these factors will be key to ensuring both successful implementation and ongoing utilisation of healthcare quality systems in emergency care. The result will not only provide a more efficient and effective service, but also positively impact patient safety and quality of care of the services delivered.

Teaching improvement science to paramedicine students: protocol for a systematic scoping review

BACKGROUND

It is now more important than ever to equip paramedic students, the likely future managers and leaders of ambulance services, with the knowledge and skills of improvement science. Effective teaching requires a range of teaching methods that will engage students actively in learning. Although the array and effectiveness of methods used for teaching improvement science to clinicians and healthcare students has been systematically reviewed, the evidence regarding the specific sub-group of paramedicine students has yet to be fully explored and synthesized in the literature. The aim of this scoping review is to systematically explore and critically appraise the current state of evidence regarding strategies to teach improvement science to paramedicine students.

METHODS

A number of electronic databases (i.e., PubMed, CINAHL, Embase, Scopus, and ERIC) and gray literature (i.e., ProQuest Dissertations and Theses, Open Thesis, and Networked Digital Library of Theses and Dissertations) will be searched for published and unpublished evidence regarding teaching improvement science to paramedicine students. Included studies will undergo narrative synthesis to examine similarities and differences and to identify patterns, themes, and relationships (e.g., how and why certain teaching strategies or methods have worked in achieving desired learning outcomes (or not) and factors that might have influenced this).

DISCUSSION

To the knowledge of the authors, this is the first review that will systematically explore and critically appraise the current state of research evidence regarding strategies to teach improvement science specifically to paramedicine students. It is anticipated that the findings of this review will help to inform academics, developers of paramedicine teaching curricula, and researchers who are planning projects in this area.

SYSTEMATIC REVIEW REGISTRATION

Scoping reviews are currently not eligible for registration on the international prospective register of systematic reviews (i.e., PROSPERO).

Emergency medical systems education may improve knowledge of pre-hospital stroke triage protocols

Background

Following the results of randomized clinical trials supporting the use of mechanical thrombectomy (MT) with tissue plasminogen activator for emergent large vessel occlusion (ELVO), our state Stroke Task Force convened to: update legislation to recognize differences between Primary Stroke Centers (PSCs) and Comprehensive Stroke Centers (CSCs); and update Emergency Medical Services (EMS) protocols to triage direct transport of suspected ELVO patients to CSCs.

Purpose

We developed a single-session training curriculum for EMS personnel focused on the Los Angeles Motor Scale (LAMS) score, its use to correctly triage patients as CSC-appropriate in the field, and our state-wide EMS stroke protocol. We assessed the effect of our training on EMS knowledge.

Methods

We assembled a focus group to develop a training curriculum and assessment questions that would mimic real-life conditions under which EMS personnel operate. Ten questions were formulated to assess content knowledge before and after training, and scores were compared using generalized mixed models.

Results

Training was provided for 179 EMS providers throughout the state.

Average pre-test score was 52.4% (95% CI 49% to 56%). Average post-test score was 85.6% (83%–88%, P<0.0001). Each of the 10 questions was individually assessed and all showed significant gains in EMS knowledge after training (P<0.0001).

Conclusions

A brief educational intervention results in substantial improvements in EMS knowledge of prehospital stroke severity scales and severity-based field triage protocols. Further study is needed to establish whether these gains in knowledge result in improved real-world performance.
