Abstract 260: COMPASS-CP for HF: An Electronic Application to Capture Patient-Reported Outcomes of Individuals with Heart Failure

Purpose: Heart failure (HF) admission variance is significantly influenced by functional, social, and behavioral health determinants. The Institute of Medicine and Centers for Medicare/Medicaid Services now recommend that these determinants be captured in the electronic health record (EHR) for personalized, value-based care and population health management. However, mechanisms for doing so within clinical workflow have not been fully developed. The purpose of this pilot project was to capture and evaluate patient-reported outcomes (PROs) prior to hospital discharge using a HF-specific version of Comprehensive Acute Care Services-Care Plan (COMPASS-CP) (Duncan et al, Circ Cardiovasc Qual Outcomes 2018), a web-based application that integrates PROs into clinical care to generate personalized electronic care plans.

Methods: Consecutively sampled patients with HF admitted to Wake Forest Baptist Medical Center Cardiology Service were assessed by a Cardiac Wellness Educator or Research Coordinator (RC) using the COMPASS-CP for HF application. The RC performed 30-day post-discharge phone calls to collect PROs and healthcare utilization.

Results: Seventy-six patients (mean 65yrs, 35% female, 31% black, 95% living at home) provided COMPASS-CP PROs. The COMPASS-CP PROs revealed 47% with fair/poor health ratings and deficits in physical function included 63% unable to walk 6 min without difficulty, 59% unable to negotiate 10 steps independently, and 24% with at least one fall within 3 months of hospital admission. Deficits in health management included 25% unable to purchase meds, 27% forgot to take meds often or sometimes, 30% without a caregiver, and 64% lacked a living will. Only 51% properly identified at least one HF risk factor and only 26% knew HF symptoms that warrant contacting their provider. Strikingly, deficits in psycho-cognitive function indicated 41% screened depression positive yet only 21% had depression listed in the EHR and 53% failed 5 minute 3-word recall. Forty-seven patients (62% of original sample, mean 62yrs, 23% female, 43% black, 93% living at home) provided 30-day PROs. The 30-day PROs revealed low Global PROMIS-10 scores (mean 30.6 on 10-50 scale), 60% with fair/poor physical health ratings, 66% with moderate to severe difficulty in everyday ADLs, 77% with moderate to severe fatigue, and 30% with ED visits and/or readmissions.

Conclusion: COMPASS-CP for HF detected global deficits known to drive all-cause healthcare utilization. This tool can aid in the generation of personalized care plans, based on PROs and availability of community services, to improve health outcomes among individuals with HF.

ACES (Accelerated Chest Pain Evaluation With Stress Imaging) Protocols Eliminate Testing Disparities in Patients With Chest Pain

BACKGROUND

Patients from racial and ethnic minority groups presenting to the Emergency Department (ED) with chest pain experience lower odds of receiving stress testing compared with nonminorities. Studies have demonstrated that care pathways administered within the ED can reduce health disparities, but this has yet to be studied as a strategy to increase stress testing equity.

METHODS

A secondary analysis from 3 randomized clinical trials involving ED patients with acute chest pain was performed to determine whether a care pathway, ACES (Accelerated Chest pain Evaluation with Stress imaging), reduces the racial disparity in index visit cardiac testing between African American (AA) and White patients. Three hundred thirty-four participants with symptoms and findings indicating intermediate to high risk for acute coronary syndrome were enrolled in 3 clinical trials. Major exclusions were ST-segment elevation, initial troponin elevation, and hemodynamic instability. Participants were randomly assigned to receive usual inpatient care, or ACES. The ACES care pathway includes placement in observation for serial cardiac markers, with an expectation for stress imaging. The primary outcome was index visit objective cardiac testing, compared among AA and White participants.

RESULTS

AA participants represented 111/329 (34%) of the study population, 80/220 (36%) of the ACES group and 31/109 (28%) of the usual care group. In usual care, objective testing occurred less frequently among AA (22/31, 71%) than among White (69/78, 88%, P = 0.027) participants, primarily driven by cardiac catheterization (3% vs. 24%; P = 0.012). In ACES, testing rates did not differ by race [AA 78/80 (98%) vs. White 138/140 (99%); P = 0.623]. At 90 days, death, MI, and revascularization did not differ in either group between AA and White participants.

CONCLUSIONS

A care pathway with the expectation for stress imaging eliminates the racial disparity among AA and White participants with chest pain in the acquisition of index-visit cardiovascular testing.

The HEART Pathway Randomized Controlled Trial One-year Outcomes

OBJECTIVE

The objective was to determine the impact of the HEART Pathway on health care utilization and safety outcomes at 1 year in patients with acute chest pain.

METHODS

Adult emergency department (ED) patients with chest pain (N = 282) were randomized to the HEART Pathway or usual care. In the HEART Pathway arm, ED providers used the HEART score and troponin measures (0 and 3 hours) to risk stratify patients. Usual care was based on American College of Cardiology/American Heart Association guidelines. Major adverse cardiac events (MACE-cardiac death, myocardial infarction [MI], or coronary revascularization), objective testing (stress testing or coronary angiography), and cardiac hospitalizations and ED visits were assessed at 1 year. Randomization arm outcomes were compared using Fisher's exact tests.

RESULTS

A total of 282 patients were enrolled, with 141 randomized to each arm. MACE at 1 year occurred in 10.6% (30/282): 9.9% in the HEART Pathway arm (14/141; 10 MIs, four revascularizations without MI) versus 11.3% in usual care (16/141; one cardiac death, 13 MIs, two revascularizations without MI; p = 0.85). Among low-risk HEART Pathway patients, 0% (0/66) had MACE, with a negative predictive value (NPV) of 100% (95% confidence interval = 93%-100%). Objective testing through 1 year occurred in 63.1% (89/141) of HEART Pathway patients compared to 71.6% (101/141) in usual care (p = 0.16). Nonindex cardiac-related hospitalizations and ED visits occurred in 14.9% (21/141) and 21.3% (30/141) of patients in the HEART Pathway versus 10.6% (15/141) and 16.3% (23/141) in usual care (p = 0.37, p = 0.36).

CONCLUSIONS

The HEART Pathway had a 100% NPV for 1-year safety outcomes (MACE) without increasing downstream hospitalizations or ED visits. Reduction in 1-year objective testing was not significant.

Monocyte Chemoattractant Protein-1 as a Predictor of Coronary Atherosclerosis in Patients Receiving Coronary Angiography

BACKGROUND

Animal studies suggest that monocyte chemoattractant protein-1 (MCP-1) is a promising biomarker for coronary artery atherosclerosis (CAA), but human studies have been inconclusive.

OBJECTIVE

To determine potential relationships between plasma MCP-1 and CAA in patients with acute chest pain.

METHODS

A secondary analysis of 150 patients enrolled in emergency department chest pain risk stratification clinical investigations was conducted. Participants with stored blood and known coronary phenotypes (determined by coronary angiography) were selected using stratified randomization such that 50 patients were included into 3 groups: (1) no angiographic evidence of CAA, (2) nonobstructive CAA, and (3) obstructive CAA (stenosis ≥ 70%). Plasma MCP-1 levels were determined by enzyme-linked immunosorbent assay. The association between MCP-1 and obstructive CAA or any CAA was modeled using logistic regression. Variables in the unreduced model included age, sex, race, prior diagnosis of CAA or acute coronary syndrome, hyperlipidemia, hypertension, diabetes, smoking, and cardiac troponin I measurement.

RESULTS

Among the 150 participants, 65.3% (98/150) had invasive coronary angiography and 34.7% (52/150) had coronary computed tomographic angiography. Myocardial infarction occurred in 27.3% (41/150) and coronary revascularization occurred in 26% (39/150) of the participants. Each 10 pg/mL increase in MCP-1 measurement was associated with an odds ratio of 1.12 (95% confidence interval, 1.06-1.19) for obstructive CAA. MCP-1 remained a significant predictor of obstructive CAA and any CAA after adjustment for age, sex, race, traditional cardiac risk factors, and cardiac troponin I.

CONCLUSIONS

MCP-1 is independently associated with CAA among emergency department patients with chest pain.

Baby Shampoo to Relieve the Discomfort of Tear Gas and Pepper Spray Exposure: A Randomized Controlled Trial

Introduction

Oleoresin capsicum (OC) or pepper spray, and tear gas (CS) are used by police and the military and produce severe discomfort. Some have proposed that washing with baby shampoo helps reduce this discomfort.

Methods

We conducted a prospective, randomized, controlled study to determine if baby shampoo is effective in reducing the severity and duration of these effects. Study subjects included volunteers undergoing OC or CS exposure as part of their police or military training. After standardized exposure to OC or CS all subjects were allowed to irrigate their eyes and skin ad lib with water. Those randomized to the intervention group were provided with baby shampoo for application to their head, neck, and face. Participants rated their subjective discomfort in two domains on a scale of 0–10 at 0, 3, 5, 10, and 15 minutes. We performed statistical analysis using a two-tailed Mann-Whitney Test.

Results

There were 58 participants. Of 40 subjects in the OC arm of the study, there were no significant differences in the ocular or respiratory discomfort at any of the time points between control (n=19) and intervention (n=21) groups. Of 18 subjects in the CS arm, there were no significant differences in the ocular or skin discomfort at any of the time points between control (n=8) and intervention (n=10) groups.

Conclusion

Irrigation with water and baby shampoo provides no better relief from OC- or CS-induced discomfort than irrigation with water alone.

Validation of the No Objective Testing Rule and Comparison to the HEART Pathway

BACKGROUND

The no objective testing rule (NOTR) is a decision aid designed to safely identify emergency department (ED) patients with chest pain who do not require objective testing for coronary artery disease.

OBJECTIVES

The objective was to validate the NOTR in a cohort of U.S. ED patients with acute chest pain and compare its performance to the HEART Pathway.

METHODS

A secondary analysis of 282 participants enrolled in the HEART Pathway randomized controlled trial was conducted. Each patient was classified as low risk or at risk by the NOTR. Sensitivity for major adverse cardiac events (MACE) at 30 days was calculated in the entire study population. NOTR and HEART Pathways were compared among patients randomized to the HEART Pathway in the parent trial using McNemar's test and the net reclassification improvement (NRI).

RESULTS

Major adverse cardiac events occurred in 22/282 (7.8%) participants, including no deaths, 16/282 (5.6%) with myocardial infarction (MI), and 6/282 (2.1%) with coronary revascularization without MI. NOTR was 100% (95% confidence interval [CI] = 84.6%-100%) sensitive for MACE and identified 78/282 patients (27.7%, 95% = CI 22.5-33.3%) as low risk. In the HEART Pathway arm (n = 141), both NOTR and HEART Pathway identified all patients with MACE as at risk. Compared to NOTR, the HEART Pathway was able to correctly reclassify 27 patients without MACE as low risk, yielding a NRI of 20.8% (95% CI = 11.3%-30.2%).

CONCLUSIONS

Within a U.S. cohort of ED patients with chest pain, the NOTR and HEART Pathway were 100% sensitive for MACE at 30 days. However, the HEART Pathway identified more patients suitable for early discharge than the NOTR.

Pediatric Needle Cricothyrotomy: A Case for Simulation in Prehospital Medicine

INTRODUCTION

A patient that cannot be oxygenated or ventilated requires immediate and effective assessment, treatment, and transportation. Pediatric needle cricothyrotomy is used infrequently, therefore providers have a tendency to lose proficiency. Simulation training and evaluation are valuable tools to improve provider experience and skill.

METHODS

A case was designed involving a 3-year-old male with a peanut allergy that presents with rash, swelling, and severe respiratory distress. The patient's respiratory distress and swelling worsens despite treatment with epinephrine and other allergic reaction medications. The patient then becomes unresponsive and impossible to oxygenate or ventilate. The primary objective of this case is airway management with needle cricothyrotomy in the pediatric population. A secondary objective is appropriate postprocedure management including appropriate ventilation rates and emergency medical transportation methods.

RESULTS

This case was initially presented to 45 paramedics. Provider comfort with managing airway emergencies in young children improved from 47% to 89%. Confidence in performing pediatric needle cricothyrotomy improved from 16% to 87%. All providers felt the exercise was valuable and 98% felt the simulation provided appropriate realism.

DISCUSSION

This scenario provides an outstanding opportunity for paramedic evaluation and training in pediatric needle cricothyrotomy and significantly improved the comfort level of providers' management of a failed pediatric airway. As we reflected on the use of this module, it was apparent that this was a very beneficial opportunity to spend one-on-one time between participants and their medical director. The training staff also benefited from the repeated emphasis of good assessment and treatment of a complex patient scenario.

Abstract WP266: EMS/Hospital Combined Education Decreased Primary Stroke Center Bypass

Introduction: Historically, community hospitals have had few options for meaningful treatment of patients presenting with acute stroke. As expertise grows in the administration of thrombolytics, primary stroke centers (PSC) fulfill an important role in the reduction of morbidity and mortality related to stroke. It is important for the PSC to partner with Emergency Medical Services (EMS) to change historical perceptions of the quality of PSC care. Education may improve teamwork and increase awareness of the PSC, thereby increasing their utilization in EMS disposition decisions.

Objective: The objective of this study is to report the impact of an education intervention on PSC bypass decisions.

Methods: The electronic patient care record database from a North Carolina county EMS system was queried as a quality improvement analysis from January 1, 2012 to February 28, 2016. This included 19 months prior to the education intervention, the year during the education intervention, and 19 months after the education intervention. All primary patient transports with Stroke/CVA, or suspected TIA as the primary or secondary impression were included. Interfacility transports were excluded. The recorded call location was determined to either be inside or outside the PSC service area. The hospital the patient was transported to was also recorded.

Results: During the pre-intervention phase 222 patients were identified, 48 of which originated in the PSC service area. Of those 48 patients, 16 bypassed the PSC (33.3%). In the post-intervention phase, 94 of 269 total patients were in PSC service area. Only 12 bypasses occurred (12.8%) which is a reduction of 61.7% in PSC bypass compared to the pre-intervention phase.

Conclusion: The period following a combined hospital/EMS educational intervention showed significant reduction in PSC bypass.

Use of the HEART Pathway with high sensitivity cardiac troponins: A secondary analysis

OBJECTIVES

The HEART Pathway combines a decision aid and serial contemporary cardiac troponin I (cTnI) measures to achieve >99% sensitivity for major adverse cardiac events (MACE) at 30days and early discharge rates >20%. However, the impact of integrating high-sensitivity troponin (hs-cTn) measures into the HEART Pathway has yet to be determined. In this analysis we compare test characteristics of the HEART Pathway using hs-cTnI, hs-cTnT, or cTnI.

DESIGN & METHODS

A secondary analysis of participants enrolled in the HEART Pathway RCT was conducted. Each patient was risk stratified by the cTn-HEART Pathway (Siemens TnI-Ultra at 0- and 3-h) and a hs-cTn-HEART Pathway using hs-cTnI (Abbott) or hs-cTnT (Roche) at 3-h. The early discharge rate, sensitivity, specificity, and negative predictive value (NPV) for MACE (death, myocardial infarction, or coronary revascularization) at 30days were calculated.

RESULTS

hs-cTnI measures were available on 133 patients. MACE occurred in 11/133 (8%) of these patients. Test characteristics for the HEART Pathway using serial cTnI vs 3hour hs-cTnI were the same: sensitivity (100%, 95%CI: 72-100%), specificity (49%, 95%CI: 40-58%), NPV (100%, 95%CI: 94-100%), and early discharge rate (45%, 95%CI: 37-54%). The HEART Pathway using hs-cTnT missed one MACE event (myocardial infarction): sensitivity (91%, 95%CI: 59-100%), specificity (48%, 95%CI: 39-57%), NPV (98%, 95%CI: 91-100%), and early discharge rate (45%, 95%CI: 37-54%).

CONCLUSIONS

There was no difference in the test characteristics of the HEART Pathway whether using cTnI or hs-cTnI, with both achieving 100% sensitivity and NPV. Use of hs-cTnT with the HEART Pathway was associated with one missed MACE.

Impact of a "Team-focused CPR" Protocol on Out-of-hospital Cardiac Arrest Survival in a Rural EMS System

BACKGROUND

More than 300,000 persons in the United States experience an out-of-hospital cardiac arrest every year. The American Heart Association emphasizes on the rapid, effective delivery of cardiac arrest interventions by bystanders and emergency medical services (EMS) on scene. In July 2013, the EMS of Randolph County, a rural county in central North Carolina, implemented a team-focused cardiopulmonary resuscitation(CPR) protocol. The protocol emphasized early chest compressions and resuscitation on scene until the return of spontaneous circulation (ROSC) or until efforts were deemed futile.

METHODS

Data were collected on all cardiac out-of-hospital cardiac arrest cases from June 30, 2012 to June 30, 2014. Outcomes for the year before the institution of the team-focused CPR protocol were compared with rates for the year following implementation.

RESULTS

A significantly higher proportion of patients achieved ROSC after protocol implementation: 25/38 [66%, 95% confidence interval (CI), 49%-80%] versus 19/67 (28%; 95% CI, 18-41%, P < 0.001). More patients survived to hospital admission in the team-focused CPR group (16/38, 42.1%, 95% CI, 26%-59%) versus the preprotocol period (10/67, 14.9%, 95% CI, 7.4%-26%, P = 0.004). Although survival to discharge was higher in the team-focused protocol period (6/38, 15.8%, 95% CI, 6.0%-31%) than the preprotocol period (4/67, 6.0%, 95% CI, 1.7%-14.6%), this did not meet statistical significance (P = 0.16).

CONCLUSION

The introduction of a team-focused CPR protocol in a single rural county-based EMS system dramatically improved ROSC and hospital admission rates, but not survival to discharge. Continued surveillance, as well as evaluation and optimization of inpatient care, is warranted.

A TASER conducted electrical weapon with cardiac biomonitoring capability: Proof of concept and initial human trial

INTRODUCTION

Despite research demonstrating the overall safety of Conducted Electrical Weapons (CEWs), commonly known by the brand name TASER(®), concerns remain regarding cardiac safety. The addition of cardiac biomonitoring capability to a CEW could prove useful and even lifesaving in the rare event of a medical crisis by detecting and analyzing cardiac rhythms during the period immediately after CEW discharge.

OBJECTIVE

To combine an electrocardiogram (ECG) device with a CEW to detect and store ECG signals while still allowing the CEW to perform its primary function of delivering an incapacitating electrical discharge.

METHODS

This work was performed in three phases. In Phase 1 standard law enforcement issue CEW cartridges were modified to demonstrate transmission of ECG signals. In Phase 2, a miniaturized ECG recorder was combined with a standard issue CEW and tested. In Phase 3, a prototype CEW with on-board cardiac biomonitoring was tested on human volunteers to assess its ability to perform its primary function of electrical incapacitation.

RESULTS

Bench testing demonstrated that slightly modified CEW cartridge wires transmitted simulated ECG signals produced by an ECG rhythm generator and from a human volunteer. Ultimately, a modified CEW incorporating ECG monitoring successfully delivered incapacitating current to human volunteers and successfully recorded ECG signals from subcutaneous CEW probes after firing.

CONCLUSION

An ECG recording device was successfully incorporated into a standard issue CEW without impeding the functioning of the device. This serves as proof-of-concept that safety measures such as cardiac biomonitoring can be incorporated into CEWs and possibly other law enforcement devices.

Medical Provider Ballistic Protection at Active Shooter Events

There is some controversy about whether ballistic protective equipment (body armor) is required for medical responders who may be called to respond to active shooter mass casualty incidents. In this article, we describe the ongoing evolution of recommendations to optimize medical care to injured victims at such an incident. We propose that body armor is not mandatory for medical responders participating in a rapid-response capacity, in keeping with the Hartford Consensus and Arlington Rescue Task Force models. However, we acknowledge that the development and implementation of these programs may benefit from the availability of such equipment as one component of risk mitigation. Many police agencies regularly retire body armor on a defined time schedule before the end of its effective service life. Coordination with law enforcement may allow such retired body armor to be available to other public safety agencies, such as fire and emergency medical services, providing some degree of ballistic protection to medical responders at little or no cost during the rare mass casualty incident. To provide visual demonstration of this concept, we tested three "retired" ballistic vests with ages ranging from 6 to 27 years. The vests were shot at close range using police-issue 9mm, .40 caliber, .45 caliber, and 12-gauge shotgun rounds. Photographs demonstrate that the vests maintained their ballistic protection and defeated all of these rounds.

North Carolina College of Emergency Physicians' Guidance Document on Emergency Medical Services

The North Carolina College of Emergency Physicians (NCCEP) Emergency Medical Services (EMS) Committee uses an evidence-based approach in writing its protocols and procedures. The most recent revision of the NCCEP document, which was started in late 2010, lasted for more than 1 year and utilized committee members from across the state. Four meetings were held at locations across North Carolina. In addition, 2 surveys were sent to get input from EMS providers. Since 2010, the document has been updated on an ongoing basis, aligning it with the latest evidence-based medicine.
