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.

Data mining-based clinical profiles of substance use-related emergency department utilizers.

OBJECTIVE: Substance-use is a prevalent presentation to the emergency department (ED); however, the clinical characterization of patients who are treated and discharged without admission for further treatment is under-investigated. The study aims to define and characterize the clinical profiles of this patient population. METHODS: Patients' presentations were examined by clinical data mining (chart review) of ED records of substance use-related events of individuals discharged without admission for further treatment. Records (N = 199) from three major hospitals in New York City from March and June 2017 were randomly sampled with primary diagnosis of alcohol, opioid-related and other psychoactive substance-use presentations. Qualitative thematic coding of clinical presentation with inter-rater reliability was performed. Quantitative distinctive validity tested independence through Pearson's chi-squared and analysis of variance using Fisher's F-test. RESULTS: Six distinct clinical profiles were identified, including, High Utilizers (chronically intoxicated with comorbid health conditions) (36.7%), Single Episode (20.1%), Service Request (14.1%), Altered Mental Status (13.6%), Overdose (9.0%), and Withdrawal (7.5%). The profiles differed (p < 0.05) in age, housing status, payor, mode of arrival, referral source, index visit time, prescribed treatment, triage acuity level, psychiatric history, and medical history. Differences (p < 0.05) between groups across clinical profiles in age and pain level at triage were observed. CONCLUSIONS: The identified clinical profiles represent the broad spectrum and complex nature of substance use-related ED utilization, highlighting critical factors of psychosocial and mental-health comorbidities. These findings provide a preliminary foundation to support person-centered interventions to decrease substance use-related ED utilization and to increase engagement/linkage of patients to addiction treatment.

AiRDose: Developing and Validating an Augmented Reality Smartphone Application for Weight Estimation and Dosing in Children.

OBJECTIVES: Inaccurate weight estimation is a contributing factor to medical error in pediatric emergencies, especially in the prehospital setting. Current American Heart Association guidelines recommend the use of length-based weight estimation tools such as the Broselow tape. We developed the AiRDose smartphone application that uses augmented reality to provide length-based weight estimates, as well as medication dosing, defibrillation energy, and equipment sizing recommendations; AiRDose was programmed to use Broselow conversions to obtain these estimates. The primary objective was to compare the length estimated by AiRDose with the actual length obtained by the standard tape measure. The secondary objectives were to compare the estimated weights and critical medication doses from AiRDose with current established methods. METHODS: In this prospective validation study, lengths and estimated weights were obtained for children presenting to 2 emergency departments using AiRDose, Broselow, and a standard tape measure; actual weight was recorded from the patient chart. Using the AiRDose estimated weights, hypothetical doses of epinephrine and lorazepam were calculated and compared with doses recommended via Broselow and to actual weight-based doses. Spearman rank correlation coefficients were calculated. We defined an acceptable difference of 20% between AiRDose and standard measurements as clinically relevant. RESULTS: Five hundred forty-nine children (mean age, 4.8 years; standard deviation [SD], 2.9 years) were recruited. There were 99.6% of AiRDose lengths within a 20% difference of tape-measure lengths. There was a significant correlation between AiRDose and tape-measure length measurements (r = 0.989, P < 0.0001), and between AiRDose and Broselow weights (r = 0.983, P < 0.0001) and AiRDose and actual weights (r = 0.886, P < 0.0001). AiRDose lorazepam and epinephrine doses correlated significantly with Broselow lorazepam (r = 0.963, P < 0.0001) and epinephrine (r = 0.966, P < 0.0001) doses. CONCLUSIONS: Anthropometric estimates and medication dose recommendations provided by AiRDose strongly correlate with established techniques. Further study will establish the feasibility of using AiRDose to accurately obtain weight estimates and medication doses for pediatric patients in the prehospital setting.

Retrospective Cohort Study of Rates of Return Emergency Department Visits Among Patients Transported Home by Ambulance.

BACKGROUND: Emergency Medical Services (EMS) is an important resource that interacts with our most vulnerable patients during transport home after hospital discharge. EMS providers may be appropriately situated to support the transition of care to the home environment. OBJECTIVES: This study aimed to determine whether patients transported home by ambulance experience higher rates of return emergency department (ED) visits and readmission compared with similar patients transported home by other means. METHODS: This was a retrospective cohort study conducted at a U.S. tertiary care academic hospital. Patients aged 65 years and over transported home via ambulance after hospital discharge between January and March 2012 were included. Rates of 72-h and 30-day ED revisits and 30-day hospital readmissions were calculated. Odds ratios were calculated and revisit rates between groups were compared. RESULTS: There were 207 patients aged 65 and over transported home by ambulance. Matched controls were found for 162 patients. Compared with the matched controls, the exposed group experienced a statistically significant higher rate of 30-day ED returns (18.519% vs. 10.494%; odds ratio [OR] 1.939; p = 0.043). The exposed group also experienced a higher rate of 72-h ED returns (2.469% vs. 0.617%; OR 4.076) and 30-day readmissions (12.346% vs. 6.173%; OR 2.141), though results did not reach statistical significance. CONCLUSION: The study findings suggest that transport home via ambulance after hospital discharge could be predictive of a high risk of recidivism independent of established readmission risk factors. Programs that expand the role of EMS to include post-transport interventions may warrant further exploration.

Correlation Between Paramedic Disaster Triage Accuracy in Screen-Based Simulations and Immersive Simulations.

Background: Disaster triage is an infrequent, high-stakes skill set used by emergency medical services (EMS) personnel. Screen-based simulation (SBS) provides easy access to asynchronous disaster triage education. However, it is unclear if the performance during a SBS correlates with immersive simulation performance. Methods: This was a nested cohort study within a randomized controlled trial (RCT). The RCT compared triage accuracy of paramedics and emergency medical technicians (EMTs) who completed an immersive simulation of a school shooting, interacted with an SBS for 13 weeks, and then completed the immersive simulation again. The participants were divided into two groups: those exposed vs. those not exposed to 60 Seconds to Survival© (60S), a disaster triage SBS. The aim of the study was to measure the correlation between SBS triage accuracy and immersive simulation triage accuracy. Improvements in triage accuracy were compared among participants in the nested study before and after interacting with 60S, and with improvements in triage accuracy in a previous study in which immersive simulations were used as an educational intervention. Results: Thirty-nine participants completed the SBS; 26 (67%) completed at least three game plays and were included in the evaluation of outcomes of interest. The mean number of plays was 8.5 (SD =7.4). Subjects correctly triaged 12.4% more patients in the immersive simulation at study completion (73.1% before, 85.8% after, P = 0.004). There was no correlation between the amount of improvement in overall SBS triage accuracy, instances of overtriage (P = 0.101), instances of undertriage (P = 0.523), and improvement in the second immersive simulation. A comparison of the pooled data from a previous immersive simulation study with the nested cohort data showed similar improvement in triage accuracy (P = 0.079). Conclusions: SBS education was associated with a significant increase in triage accuracy in an immersive simulation, although triage accuracy demonstrated in the SBS did not correlate with the performance in the immersive simulation. This improvement in accuracy was similar to the improvement seen when immersive simulation was used as the educational intervention in a previous study.

National Assessment of Quality Programs in Emergency Medical Services.

OBJECTIVE: This study aims to understand the adoption of clinical quality measurement throughout the United States on an EMS agency level, the features of agencies that do participate in quality measurement, and the level of physician involvement. It also aims to barriers to implementing quality improvement initiatives in EMS. METHODS: A 46-question survey was developed to gather agency level data on current quality improvement practices and measurement. The survey was distributed nationally via State EMS Offices to EMS agencies nation-wide using Surveymonkey©. A convenience sample of respondents was enrolled between August and November, 2015. Univariate, bivariate and multiple logistic regression analyses were conducted to describe demographics and relationships between outcomes of interest and their covariates using SAS 9.3©. RESULTS: A total of 1,733 surveys were initiated and 1,060 surveys had complete or near-complete responses. This includes agencies from 45 states representing over 6.23 million 9-1-1 responses annually. Totals of 70.5% (747) agencies reported dedicated QI personnel, 62.5% (663) follow clinical metrics and 33.3% (353) participate in outside quality or research program. Medical director hours varied, notably, 61.5% (649) of EMS agencies had <5 hours of medical director time per month. Presence of medical director time was correlated with tracking of QI measures. Air medical [OR 9.64 (1.13, 82.16)] and hospital-based EMS agencies [OR 2.49 (1.36, 4.59)] were more likely to track quality measures compared to fire-based agencies. Agencies in rural only environments were less likely to follow clinical quality metrics. (OR 0.47 CI 0.31 -0.72 p < 0.0004). For those that track QI measures, the most common are; Response Time (Emergency) (68.3%), On-Scene Time (66.4%), prehospital stroke screen (64.6%), aspirin administration (64.5%), and 12 lead ECG in chest pain patients (63.0%). CONCLUSIONS: EMS agencies in the United States have significant practice variability with regard to quality improvement resources, medical direction and specific clinical quality measures. More research is needed to understand the impact of this variation on patient care outcomes.

Supporting the on-call primary care physician with community paramedicine.

Prior to being referred to the emergency department (ED), patients such as the frail elderly often call their primary care physician. However, the on-call primary care physician or covering provider does not always have the tools to make an accurate and safe assessment over the phone or to treat patients remotely. This often results in preventable transport to an ED, avoidable admissions and iatrogenic events. An opportunity exists to reduce unnecessary ED referrals by enhancing the capabilities of the on-call primary care physician. In this communication, we describe the development of a community paramedicine programme that supports on-call primary care providers managing a high-risk patient population with the goal of reducing avoidable ED referrals.

Quantitative Analysis of the Content of EMS Handoff of Critically Ill and Injured Patients to the Emergency Department.

OBJECTIVES: Patient handoff occurs when responsibility for patient diagnosis, treatment, or ongoing care is transferred from one healthcare professional to another. Patient handoff is an integral component of quality patient care and is increasingly identified as a potential source of medical error. However, evaluation of handoff from field providers to ED personnel is limited. We here present a quantitative analysis of the information transferred from EMS providers to ED physicians during handoff of critically ill and injured patients. METHODS: This study was conducted at an urban academic medical center with an emergency department census of greater than 100,000 visits annually. All patients arriving to our institution by EMS and meeting predefined triage criteria are brought immediately to the ED resuscitation area upon EMS arrival. Handoff from EMS to ED providers occurring in the resuscitation area was observed and audio recorded by trained research assistants and subsequently coded for content. The emergency department team as well as EMS were blinded to study design. RESULTS: Ninety patient handoffs were evaluated. In 78% (95%CI = 70.0-86.7) of all handoffs, EMS provided a chief concern. In 58% (95%CI = 47.7-67.7) of handoffs EMS provided a description of the scene and in 57% (95%CI = 46.7-66.7) they provided a complete set of vital signs. In 47% (95%CI = 31.3-57.5) of handoffs pertinent physical exam findings were described. The EMS provider gave an overall assessment of the patient's clinical status in 31% (95%CI = 21.6-40.3) of cases. Significantly more paramedic handoffs included vital signs (70% vs. 37%, χ2 = 9.69, p = 0.002) and physical exam findings (63% vs. 23%, χ2 = 14.11, p < 0.001). Paramedics were more likely to provide an overall assessment (39% vs. 17%, χ2 = 4.71, p < 0.05). CONCLUSIONS: While patient handoff is a critical component of safe and effective patient care, our study confirms previous literature demonstrating poor quality handoff from EMS to ED providers in critically ill and injured patients. Our analysis demonstrates the need for further training in the provision of patient handoff.

Lesson From the New York City Out-of-Hospital Uncontrolled Donation After Circulatory Determination of Death Program.

STUDY OBJECTIVE: In 2006, the Institute of Medicine emphasized substantial potential to expand organ donation opportunities through uncontrolled donation after circulatory determination of death (uDCDD). We pilot an out-of-hospital uDCDD kidney program for New York City in partnership with communities that it was intended to benefit. We evaluate protocol process and outcomes while identifying barriers to success and means for improvement. METHODS: We conducted a prospective, participatory action research study in Manhattan from December 2010 to May 2011. Daily from 4 to 12 pm, our organ preservation unit monitored emergency medical services (EMS) frequencies for cardiac arrests occurring in private locations. After EMS providers independently ordered termination of resuscitation, organ preservation unit staff determined clinical eligibility and donor status. Authorized parties, persons authorized to make organ donation decisions, were approached about in vivo preservation. The study population included organ preservation unit staff, authorized parties, passersby, and other New York City agency personnel. Organ preservation unit staff independently documented shift activities with daily operations notes and teleconference summaries that we analyzed with mixed qualitative and quantitative methods. RESULTS: The organ preservation unit entered 9 private locations; all the deceased lacked previous registration, although 4 met clinical screening eligibility. No kidneys were recovered. We collected 837 notes from 35 organ preservation unit staff. Despite frequently recounting protocol breaches, most responses from passersby including New York City agencies were favorable. No authorized parties were offended by preservation requests, yielding a Bayesian posterior median 98% (95% credible interval 76% to 100%). CONCLUSION: In summary, the New York City out-of-hospital uDCDD program was not feasible. There were frequent protocol breaches and confusion in determining clinical eligibility. In the small sample of authorized persons we encountered during the immediate grieving period, negative reactions were infrequent.

Patient Perspectives on EMS Alternate Destination Models.

INTRODUCTION: Studies have shown that a large number of ambulance transports to emergency departments (ED) could have been safely treated in an alternative environment, prompting interest in the development of more patient-centered models for prehospital care. We examined patient attitudes, perspectives, and agreement/comfort with alternate destinations and other proposed innovations in Emergency Medical Services (EMS) care delivery and determined whether demographic, socioeconomic, acuity, and EMS utilization history factors impact levels of agreement. METHODS: We conducted a cross-sectional study on a convenience sample of patients and caregivers presenting to an urban academic ED between July 2012 and May 2013. Respondents were surveyed on levels of agreement with 13 statements corresponding to various aspects of a proposed patient-centered emergency response system including increased EMS access to healthcare records, shared decision making with the patient and/or primary care physician, transport to alternative destinations, and relative importance of EMS assessment versus transportation. Information on demographic and socioeconomic factors, level of acuity, and EMS utilization history were also determined via survey and chart review. Responses were analyzed descriptively and compared across patient characteristics using chi-square and regression analyses. RESULTS: A total of 621 patients were enrolled. The percentage of patients who agreed or strongly agreed with each of the 13 statements ranged from 48.2 to 93.8%. About 86% agreed with increased EMS access to healthcare records; approximately 72% agreed with coordinating disposition decisions with a primary physician; and about 58% supported transport to alternative destinations for low acuity conditions. No association was found between levels of agreement and the patient's level of acuity or EMS utilization history. Only Black or Hispanic race showed isolated associations with lower rates of agreement with some aspects of an innovative EMS care delivery model. CONCLUSION: A substantial proportion of patients surveyed in this cross sectional study agreed with a more patient-centered approach to prehospital care where a 9-1-1 call could be met with a variety of treatment and transportation options. Agreement was relatively consistent among a diverse group of patients with varying demographics, levels of acuity and EMS utilization history. MeSH Key words: emergency medical services; triage; telemedicine; surveys and questionnaires; transportation of patients.

Cardiopulmonary Resuscitation in Resource-limited Health Systems-Considerations for Training and Delivery.

In the past 50 years, cardiopulmonary resuscitation (CPR) has gained widespread recognition as a life-saving skill that can be taught successfully to the general public. Cardiopulmonary resuscitation can be considered a cost-effective intervention that requires minimal classroom training and low-cost equipment and supplies; it is commonly taught throughout much of the developed world. But, the simplicity of CPR training and its access for the general public may be misleading, as outcomes for patients in cardiopulmonary arrest are poor and survival is dependent upon a comprehensive "chain-of-survival," which is something not achieved easily in resource-limited health care settings. In addition to the significant financial and physical resources needed to both train and develop basic CPR capabilities within a community, there is a range of ethical questions that should also be considered. This report describes some of the financial and ethical challenges that might result from CPR training in low- and middle-income countries (LMICs). It is determined that for many health care systems, CPR training may have financial and ethically-deleterious, unintended consequences. Evidence shows Basic Life Support (BLS) skills training in a community is an effective intervention to improve public health. But, health care systems with limited resources should include CPR training only after considering the full implications of that intervention.

Uncontrolled organ donation after circulatory determination of death: US policy failures and call to action.

In the United States, more than 115,000 patients are wait-listed for organ transplants despite that there are 12,000 patients each year who die or become too ill for transplantation. One reason for the organ shortage is that candidates for donation must die in the hospital, not the emergency department (ED), either from neurologic or circulatory-respiratory death under controlled circumstances. Evidence from Spain and France suggests that a substantial number of deaths from cardiac arrest may qualify for organ donation using uncontrolled donation after circulatory determination of death (uDCDD) protocols that rapidly initiate organ preservation in out-of-hospital and ED settings. Despite its potential, uDCDD has been criticized by panels of experts that included neurologists, intensivists, attorneys, and ethicists who suggest that organ preservation strategies that reestablish oxygenated circulation to the brain retroactively negate previous death determination based on circulatory-respiratory criteria and hence violate the dead donor rule. In this article, we assert that in uDCDD, all efforts at saving lives are exhausted before organ donation is considered, and death is determined according to "irreversible cessation of circulatory and respiratory functions" evidenced by "persistent cessation of functions during an appropriate period of observation and/or trial of therapy." Therefore, postmortem in vivo organ preservation with chest compressions, mechanical ventilation, and extracorporeal membrane oxygenation is legally and ethically appropriate. As frontline providers for patients presenting with unexpected cardiac arrest, emergency medicine practitioners need be included in the uDCDD debate to advocate for patients and honor the wishes of the deceased.

A rationale in support of uncontrolled donation after circulatory determination of death.

In the United States, when people die unexpectedly, they are usually not considered as organ donors because of the difficulty of keeping organs viable when death occurs outside the hospital, in "uncontrolled" circumstances. New protocols to permit donation in these cases have renewed the debate about how we decide whether a person has died- and whether the moral imperative to help those in need of transplant should affect the determination of death.

Mobile Integrated Health Interventions for Older Adults: A Systematic Review.

Background and Objectives: Mobile integrated health (MIH) interventions have not been well described in older adult populations. The objective of this systematic review was to evaluate the characteristics and effectiveness of MIH programs on health-related outcomes among older adults. Research Design and Methods: We searched Ovid MEDLINE, Ovid EMBASE, CINAHL, AgeLine, Social Work Abstracts, and The Cochrane Library through June 2021 for randomized controlled trials or cohort studies evaluating MIH among adults aged 65 and older in the general community. Studies were screened for eligibility against predefined inclusion/exclusion criteria. Using at least 2 independent reviewers, quality was appraised using the Downs and Black checklist and study characteristics and findings were synthesized and evaluated for potential bias. Results: Screening of 2,160 records identified 15 studies. The mean age of participants was 67 years. The MIH interventions varied in their focus, community paramedic training, types of assessments and interventions delivered, physician oversight, use of telemedicine, and post-visit follow-up. Studies reported significant reductions in emergency call volume (5 studies) and immediate emergency department (ED) transports (3 studies). The 3 studies examining subsequent ED visits and 4 studies examining readmission rates reported mixed results. Studies reported low adverse event rates (5 studies), high patient and provider satisfaction (5 studies), and costs equivalent to or less than usual paramedic care (3 studies). Discussion and Implications: There is wide variability in MIH provider training, program coordination, and quality-based metrics, creating heterogeneity that make definitive conclusions challenging. Nonetheless, studies suggest MIH reduces emergency call volume and ED transport rates while improving patient experience and reducing overall health care costs.

Applications and User Perceptions of Smart Glasses in Emergency Medical Services: Semistructured Interview Study.

BACKGROUND: Smart glasses have been gaining momentum as a novel technology because of their advantages in enabling hands-free operation and see-what-I-see remote consultation. Researchers have primarily evaluated this technology in hospital settings; however, limited research has investigated its application in prehospital operations. OBJECTIVE: The aim of this study is to understand the potential of smart glasses to support the work practices of prehospital providers, such as emergency medical services (EMS) personnel. METHODS: We conducted semistructured interviews with 13 EMS providers recruited from 4 hospital-based EMS agencies in an urban area in the east coast region of the United States. The interview questions covered EMS workflow, challenges encountered, technology needs, and users' perceptions of smart glasses in supporting daily EMS work. During the interviews, we demonstrated a system prototype to elicit more accurate and comprehensive insights regarding smart glasses. Interviews were transcribed verbatim and analyzed using the open coding technique. RESULTS: We identified four potential application areas for smart glasses in EMS: enhancing teleconsultation between distributed prehospital and hospital providers, semiautomating patient data collection and documentation in real time, supporting decision-making and situation awareness, and augmenting quality assurance and training. Compared with the built-in touch pad, voice commands and hand gestures were indicated as the most preferred and suitable interaction mechanisms. EMS providers expressed positive attitudes toward using smart glasses during prehospital encounters. However, several potential barriers and user concerns need to be considered and addressed before implementing and deploying smart glasses in EMS practice. They are related to hardware limitations, human factors, reliability, workflow, interoperability, and privacy. CONCLUSIONS: Smart glasses can be a suitable technological means for supporting EMS work. We conclude this paper by discussing several design considerations for realizing the full potential of this hands-free technology.

Using Mobile Integrated Health and telehealth to support transitions of care among patients with heart failure (MIGHTy-Heart): protocol for a pragmatic randomised controlled trial.

INTRODUCTION: Nearly one-quarter of patients discharged from the hospital with heart failure (HF) are readmitted within 30 days, placing a significant burden on patients, families and health systems. The objective of the 'Using Mobile Integrated Health and Telehealth to support transitions of care among patients with Heart failure' (MIGHTy-Heart) study is to compare the effectiveness of two postdischarge interventions on healthcare utilisation, patient-reported outcomes and healthcare quality among patients with HF. METHODS AND ANALYSIS: The MIGHTy-Heart study is a pragmatic comparative effectiveness trial comparing two interventions demonstrated to improve the hospital to home transition for patients with HF: mobile integrated health (MIH) and transitions of care coordinators (TOCC). The MIH intervention bundles home visits from a community paramedic (CP) with telehealth video visits by emergency medicine physicians to support the management of acute symptoms and postdischarge care coordination. The TOCC intervention consists of follow-up phone calls from a registered nurse within 48-72 hours of discharge to assess a patient's clinical status, identify unmet clinical and social needs and reinforce patient education (eg, medication adherence and lifestyle changes). MIGHTy-Heart is enrolling and randomising (1:1) 2100 patients with HF who are discharged to home following a hospitalisation in two New York City (NY, USA) academic health systems. The coprimary study outcomes are all-cause 30-day hospital readmissions and quality of life measured with the Kansas City Cardiomyopathy Questionnaire 30 days after hospital discharge. The secondary endpoints are days at home, preventable emergency department visits, unplanned hospital admissions and patient-reported symptoms. Data sources for the study outcomes include patient surveys, electronic health records and claims submitted to Medicare and Medicaid. ETHICS AND DISSEMINATION: All participants provide written or verbal informed consent prior to randomisation in English, Spanish, French, Mandarin or Russian. Study findings are being disseminated to scientific audiences through peer-reviewed publications and presentations at national and international conferences. This study has been approved by: Biomedical Research Alliance of New York (BRANY #20-08-329-380), Weill Cornell Medicine Institutional Review Board (20-08022605) and Mt. Sinai Institutional Review Board (20-01901). TRIAL REGISTRATION NUMBER: Clinicaltrials.gov, NCT04662541.

Feasibility of the Transport PLUS intervention to improve the transitions of care for patients transported home by ambulance: a non-randomized pilot study.

BACKGROUND: The growing population of patients over the age of 65 faces particular vulnerability following discharge after hospitalization or an emergency room visit. Specific areas of concern include a high risk for falls and poor comprehension of discharge instructions. Emergency medical technicians (EMTs), who frequently transport these patients home from the hospital, are uniquely positioned to aid in mitigating transition of care risks and are both trained and utilized to do so using the Transport PLUS intervention. METHODS: Existing literature and focus groups of various stakeholders were utilized to develop two checklists: the fall safety assessment (FSA) and the discharge comprehension assessment (DCA). EMTs were trained to administer the intervention to eligible patients in the geriatric population. Using data from the checklists, follow-up phone calls, and electronic health records, we measured the presence of hazards, removal of hazards, the presence of discharge comprehension issues, and correction or reinforcement of comprehension. These results were validated during home visits by community health workers (CHWs). Feasibility outcomes included patient acceptance of the Transport PLUS intervention and accuracy of the EMT assessment. Qualitative feedback via focus groups was also obtained. Clinical outcomes measured included 3-day and 30-day readmission or ED revisit. RESULTS: One-hundred three EMTs were trained to administer the intervention and participated in 439 patient encounters. The intervention was determined to be feasible, and patients were highly amenable to the intervention, as evidenced by a 92% and 74% acceptance rate of the DCA and FSA, respectively. The majority of patients also reported that they found the intervention helpful (90%) and self-reported removing 40% of fall hazards; 85% of such changes were validated by CHWs. Readmission/revisit rates are also reported. CONCLUSIONS: The Transport PLUS intervention is a feasible, easily implemented tool in preventative community paramedicine with high levels of patient acceptance. Further study is merited to determine the effectiveness of the intervention in reducing rates of readmission or revisit. A randomized control trial has since begun utilizing the knowledge gained within this study.

Utilization of emergency medical services in a large urban area: description of call types and temporal trends.

BACKGROUND: Emergency medical services (EMS) systems are used by the public for a range of medically related problems. OBJECTIVE: To understand and analyze the patterns of EMS utilization and trends over time in a large urban EMS system so that we may better direct efforts toward improving those services. METHODS: The 63 call type designations from all New York City (NYC) 9-1-1 EMS calls between 1999 and 2007 were obtained and grouped into 10 broad and 30 specific medical categories. Aggregated numbers of total EMS calls and individual categories were divided by NYC resident population estimates to determine utilization rates. Temporal trends were evaluated for statistical significance with Spearman's rho (ρ). RESULTS: There were 9,916,904 EMS calls between 1999 and 2007, with an average of 1,101,878 calls/year. Utilization rates increased from 129.5 to 141.9 calls/1,000 residents/year over the study period (average annual rise of 1.16%). Among all medical/surgical call types (excluding trauma), there was an average annual increase of 1.8%/year. The most substantial increases were among "psychiatric/drug related" (+5.6%/year), "generalized illness" (+3.2%/year), and "environmental related" calls (+2.9%/year). The largest decrease was among "respiratory" calls (-1.2%/year), specifically for "asthma" (-5.0%/year). For trauma call types, there was an annual average decrease of 0.4%/year, with the category of "violence related" calls having the greatest decline (-3.3%/year). CONCLUSION: There was an increase in overall EMS utilization rates, though not all call types rose uniformly. Rather, a number of significant trends were identified reflecting either changing medical needs or changing patterns of EMS utilization in NYC's population.

Simulation-Based Orientation for Emergency Medicine Residents Participating in EMS Ride-Alongs.

Introduction: Emergency medicine resident physicians are required to complete observational ride-alongs with emergency medical services (EMS) units as part of their curriculum as per the ACGME. We created this curriculum to expose emergency medicine residents to the equipment they will encounter in the prehospital setting, discuss basic EMS operations and the challenges of working in the prehospital environment, and review the limitations that restrict care provided by EMS professionals. Methods: We created a series of five simulation cases for resident physicians participating in an EMS ride-along rotation. Each case was implemented with three to four residents at a time. A critical action checklist was used to assess participants during the scenarios. Following each simulation, a debriefing was conducted to discuss EMS operations and the impact on providers. At the conclusion of the session, participants completed a course evaluation survey. Results: Thirteen emergency medicine resident physicians took part in this curriculum from October 2020 through January 2021. Results indicated that the participants gained insight into the prehospital environment, felt more prepared to complete their ride-alongs, and were engaged and satisfied with the introduction to EMS program. Discussion: Simulation allowed emergency medicine residents to be exposed to the complex nature of prehospital care and prepared them for their ride-along sessions. The five cases provided significant breadth and depth of potential prehospital care issues, and the residents were able to discuss the medical, policy, and operational challenges presented as part of each case.
