Achieving Equity in EMS Care and Patient Outcomes Through Quality Management Systems: A Position Statement.

Improving health and safety in our communities requires deliberate focus and commitment to equity. Inequities are differences in access, treatment, and outcomes between individuals and across populations that are systemic, avoidable, and unjust. Within health care in general, and Emergency Medical Services (EMS) in particular, there are demonstrated inequities in the quality of care provided to patients based on a number of characteristics linked to discrimination, exclusion, or bias. Given the critical role that EMS plays within the health care system, it is imperative that EMS systems reduce inequities by delivering evidence-based, high-quality care for the communities and patients we serve. To achieve equity in EMS care delivery and patient outcomes, the National Association of EMS Physicians recommends that EMS systems and agencies: make health equity a strategic priority and commit to improving equity at all levels.assess and monitor clinical and safety quality measures through the lens of inequities as an integrated part of the quality management process.ensure that data elements are structured to enable equity analysis at every level and routinely evaluate data for limitations hindering equity analysis and improvement.involve patients and community stakeholders in determining data ownership and stewardship to ensure its ongoing evolution and fitness for use for measuring care inequities.address biases as they translate into the quality of care and standards of respect for patients.pursue equity through a framework rooted in the principles of improvement science.

Social Determinants of Health in EMS Records: A Mixed-methods Analysis Using Natural Language Processing and Qualitative Content Analysis.

Introduction: Social determinants of health (SDoH) are known to impact the health and well-being of patients. However, information regarding them is not always collected in healthcare interactions, and healthcare professionals are not always well-trained or equipped to address them. Emergency medical services (EMS) professionals are uniquely positioned to observe and attend to SDoH because of their presence in patients' environments; however, the transmission of that information may be lost during transitions of care. Documentation of SDoH in EMS records may be helpful in identifying and addressing patients' insecurities and improving their health outcomes. Our objective in this study was to determine the presence of SDoH information in adult EMS records and understand how such information is referenced, appraised, and linked to other determinants by EMS personnel. Methods: Using EMS records for adult patients in the 2019 ESO Data Collaborative public-use research dataset using a natural language processing (NLP) algorithm, we identified free-text narratives containing documentation of at least one SDoH from categories associated with food, housing, employment, insurance, financial, and social support insecurities. From the NLP corpus, we randomly selected 100 records from each of the SDoH categories for qualitative content analysis using grounded theory. Results: Of the 5,665,229 records analyzed by the NLP algorithm, 175,378 (3.1%) were identified as containing at least one reference to SDoH. References to those SDoH were centered around the social topics of accessibility, mental health, physical health, and substance use. There were infrequent explicit references to other SDoH in the EMS records, but some relationships between categories could be inferred from contexts. Appraisals of patients' employment, food, and housing insecurities were mostly negative. Narratives including social support and financial insecurities were less negatively appraised, while those regarding insurance insecurities were mostly neutral and related to EMS operations and procedures. Conclusion: The social determinants of health are infrequently documented in EMS records. When they are included, they are infrequently explicitly linked to other SDoH categories and are often negatively appraised by EMS professionals. Given their unique position to observe and share patients' SDoH information, EMS professionals should be trained to understand, document, and address SDoH in their practice.

A Qualitative Analysis of the Experiences of EMS Clinicians in Recognizing and Treating Witnessed Cardiac Arrests.

BACKGROUND: Survival from out of hospital cardiac arrest (OHCA) increases when effective cardiopulmonary resuscitation (CPR) and defibrillation are performed early. Patients who suffer OHCA in front of emergency medical services (EMS) clinicians have greater likelihood of survival, but little is known about how EMS clinicians think about and experience those events. We sought to understand how EMS clinicians assessed patients who devolved to cardiac arrest in their presence and uncover the perceived barriers and facilitators associated with recognizing and treating witnessed OHCAs. METHODS: EMS clinicians who had attended an EMS-witnessed OHCA and consented to participate were interviewed within 72 hours of the index case. Transcripts of the interviews were coded through the consolidated framework for implementation research to understand enabling and constraining factors involved and the predictability and anticipation of OHCA and subsequent management of patient care. Utstein data points, interventions, and associated times were extracted from the medical records. RESULTS: We interviewed 29 EMS clinicians who attended 27 EMS-witnessed OHCAs. Twenty-six (96.3%) of the EMS-witnessed OHCAs were preceded by prodromal symptoms and were classified as predictable. Of the predictable cases, clinicians anticipated 53.8% of them and attributed the prodromes of other cases to serious but not peri-arrest etiologies. Participants described various environmental, crew, and intrapersonal enabling and constraining factors associated with recognizing and treating EMS-witnessed OHCAs. Environmental elements included issues of safety and physical locations, crew elements included familiarity with their partners and working with them in the past, and intrapersonal elements included abilities to collect information and stress associated with responding to and managing the calls. CONCLUSION: Recognition and treatment of EMS-witnessed OHCAs are influenced by numerous environmental, crew, and intrapersonal factors. Future training and education on OHCA should include diverse locations, situations, and crew make-up, along with nontraditional patient complaints to broaden experiences associated with cardiac arrest management.

A Change from a Spinal Immobilization to a Spinal Motion Restriction Protocol was Not Associated with an Increase in Disabling Spinal Cord Injuries.

BACKGROUND: Over the past decade, Emergency Medical Service (EMS) systems decreased backboard use as they transition from spinal immobilization (SI) protocols to spinal motion restriction (SMR) protocols. Since this change, no study has examined its effect on the neurologic outcomes of patients with spine injuries. OBJECTIVES: The object of this study is to determine if a state-wide protocol change from an SI to an SMR protocol had an effect on the incidence of disabling spinal cord injuries. METHODS: This was a retrospective review of patients in a single Level I trauma center before and after a change in spinal injury protocols. A two-step review of the record was used to classify spinal cord injuries as disabling or not disabling. A binary logistic regression was used to determine the effects of protocol, gender, age, level of injury, and mechanism of injury (MOI) on the incidence of significant disability from a spinal cord injury. RESULTS: A total of 549 patients in the SI period and 623 patients in the SMR period were included in the analysis. In the logistic regression, the change from an SI protocol to an SMR protocol did not demonstrate a significant effect on the incidence of disabling spinal injuries (OR: 0.78; 95% CI, 0.44 - 1.36). CONCLUSION: This study did not demonstrate an increase in disabling spinal cord injuries after a shift from an SI protocol to an SMR protocol. This finding, in addition to existing literature, supports the introduction of SMR protocols and the decreased use of the backboard.

Changes in Field Termination of Resuscitation and Survival Rates After an Educational Intervention to Promote on Scene Resuscitation for Out-of-Hospital Cardiac Arrest.

BACKGROUND: Emergency medical services (EMS) agencies with higher field termination-of-resuscitation (TOR) rates tend to have higher survival rates from out-of-hospital cardiac arrest (OHCA). Whether EMS agencies can improve survival rates through efforts to focus on resuscitation on scene and optimize TOR rates is unknown. OBJECTIVE: The goal of this study was to determine if an EMS agency's efforts to enhance on-scene resuscitation were associated with increased TOR and OHCA survival with favorable neurologic outcome. METHODS: A single-city, retrospective analysis of prospectively collected 2017 quality assurance data was conducted. Patient demographics, process, and outcome measures were compared before and after an educational intervention to increase field TOR. The primary outcome measure was survival to hospital discharge with favorable neurologic status. RESULTS: There were 320 cases that met inclusion criteria. No differences in age, gender, location, witnessed arrest, bystander cardiopulmonary resuscitation, initial shockable rhythm, or presumed cardiac etiology were found. After the intervention, overall TOR rate increased from 39.6% to 51.1% (p = 0.06). Among subjects transported without return of spontaneous circulation (ROSC), average time on scene increased from 26.4 to 34.2 min (p = 0.02). Rates of sustained ROSC and survival to hospital admission were similar between periods. After intervention, there was a trend toward increased survival to hospital discharge rate (relative risk [RR] 2.09; 95% confidence interval [CI] 0.74-5.91) and an increase in survival with favorable neurologic status rate (RR 5.96; 95% CI 0.80-44.47). CONCLUSION: This study described the association between an educational intervention focusing on optimization of resuscitation on scene and OHCA process and outcome measures. Field termination has the potential to serve as a surrogate marker for aggressively treating OHCA patients on scene.

Compulsory Use of the Backboard is Associated with Increased Frequency of Thoracolumbar Imaging.

BACKGROUND: Backboards have been shown to cause pain in uninjured patients. This may alter physical exam findings, leading emergency department (ED) providers to suspect a spinal injury when none exists resulting in additional imaging of the thoracolumbar spine. New York had previously employed a "Spinal Immobilization" protocol that included compulsory backboard application for all patients with suspected spinal injuries. In 2015, New York instituted a new "Spinal Motion Restriction" protocol that made backboard use optional for these patients. The objective of this study was to determine if this protocol change was associated with decreased backboard utilization and ED thoracolumbar spine imaging. METHODS: This was a retrospective before-and-after chart review of subjects transported by a single emergency medical services (EMS) agency to one of four EDs for emergency calls dispatched as motor vehicle collisions (MVC). EMS and ED data were included for all calls within a 6-month interval before and after the protocol change. The protocol change was implemented in the second half of 2015. Subject demographics, backboard use, and spine imaging were reviewed for the intervals January-June 2015 and January-June 2016. RESULTS: There were 818 subjects in the before period and 796 subjects in the after period. Subjects were similar in terms of gender, age and type of MVC in both periods. A backboard was utilized for 440 (54%) subjects in the before period and 92 (12%) subjects in the after period (p < 0.001). ED thoracic spine imaging was performed on 285 (35%) subjects in the before period, and 235 (30%) subjects in the after period (p = 0.02). ED lumbar spine imaging was performed for 335 (41%) subjects in the before period, and 281 (35%) subjects in the after period (p = 0.02). CONCLUSION: A shift from a spinal immobilization protocol to a spinal motion restriction protocol was associated with a decrease in backboard utilization by EMS providers and a decrease in thoracolumbar spine imaging by ED providers.

Intravenous vs. intraosseous access and return of spontaneous circulation during out of hospital cardiac arrest.

INTRODUCTION: Guidelines endorse intravenous (IV) and intraosseous (IO) medication administration for cardiac arrest treatment. Limited clinical evidence supports this recommendation. A multiagency, retrospective study was performed to determine the association between parenteral access type and return of spontaneous circulation (ROSC) in out of hospital cardiac arrest. METHODS: This was a structured, retrospective chart review of emergency medical services (EMS) records from three agencies. Data was analyzed from adults who suffered OHCA and received epinephrine through EMS established IV or IO access during the 18-month study period. Per regional EMS protocols, choice of parenteral access type was at the provider's discretion. Non-inferiority analysis was performed comparing the association between first access type attempted and ROSC at time of emergency department arrival. RESULTS: 1310 subjects met inclusion criteria and were included in the analysis. Providers first attempted parenteral access via IV route in 788 (60.15%) subjects. Providers first attempted parenteral access via IO route in 552 (39.85%) subjects. Rates of ROSC at time of ED arrival were 19.67% when IV access was attempted first and 19.92% when IO access was attempted first. An IO first approach was non-inferior to an IV first approach based on the primary end point ROSC at time of emergency department arrival (p=0.01). CONCLUSION: An IO first approach was non-inferior to an IV first approach based on the end point ROSC at time of emergency department arrival.
