Assessing Efficiency in a Static-Based 9-1-1 Ambulance Service: An Analysis of Operational Performance Metrics.

OBJECTIVES: This study sought to evaluate performance indicators to assist a static-based 9-1-1 agency in defining its response efficiency. METHODS: Initial assessment of three metrics-unit hour utilization (UHU), fractile response intervals, and level 0 frequency (occurrence when no ambulances are available to respond)-suggested the agency's response over its four coverage zones was inefficient, so an operational change was implemented: an ambulance was relocated from one service area to another to improve the overall response productivity. A 2-year retrospective analysis was performed to determine the impact ambulance relocation had on the three targeted measurements. RESULTS: The operational change resulted in a statistically significant change in unit hour utilization, a non-significant increase in fractile response intervals, and a statistically significant reduction in level 0 frequency from pre- to post-operational change times. CONCLUSIONS: These findings suggest a way to evaluate the efficiency of static-based ambulance deployment and potentially identify strategies for redeployment.

Evaluation of medications used for opioid use disorder in emergency departments: A cross-sectional analysis of the 2020 National Hospital Ambulatory Medical Care Survey.

INTRODUCTION: Opioid use disorder (OUD) is a significant health issue impacting millions in the United States (US). Medications used for OUD (MOUD) (e.g., buprenorphine, methadone, naltrexone) and medications for overdose and symptom management (e.g., naloxone, clonidine) have been shown to be safe and effective tools in clinical management. MOUD therapy in Emergency Departments (EDs) improves patient outcomes and enhances engagement with formal addiction treatment; however, provider factors and institutional barriers have created hurdles to ED-based MOUD treatment and heterogeneity in ED based OUD care. We used a nationally representative dataset, the National Hospital Ambulatory Medical Care Survey (NHAMCS) to characterize MOUD prescribing practices across patient demographics, geographic regions, payers, providers, and comorbidities in EDs. METHODS: NHAMCS is a survey conducted by the US Census Bureau assessing utilization of ambulatory healthcare services nationally. Survey staff compile encounter records from a nationally representative sample of EDs. We conducted a cross-sectional study using this data to assess visits in 2020 among patients aged 18-64 presenting with an opioid overdose or OUD. We estimated the proportion of patients who had any MOUD, clonidine, or naloxone treatment and 95% confidence intervals (CI). We modeled the association between patient demographic, location, comorbidities, and provider characteristics with receipt of MOUD treatment as unadjusted odds ratios (OR) and 95% CI. RESULTS: There was a weighted frequency of 469,434 patients who were discharged from EDs after being seen for OUD or overdose. Naloxone, clonidine, and buprenorphine were the most frequent treatments administered and/or prescribed for OUDs or overdose. Overall, 54,123 (11.5%, 95%CI 0-128,977) patients who were discharged from the ED for OUDs or overdose received at least one type of MOUD. Hispanic race, (OR 17.9, 95%CI 1.33-241.90) and Western region (OR43.77, 95%CI 2.97-645.27) were associated with increased odds of receiving MOUDs, while arrival by ambulance was associated with decreased odds of receiving MOUDs (OR0.01, 95%CI 0.001-0.19). Being seen by an APP or physician assistant was associated with MOUD treatment (OR 16.68, 95%CI: 1.41-152.33; OR: 13.84, 95%CI: 3.58-53.51, respectively). CONCLUSION: Our study findings suggest that MOUD and other medications for opioid overdose are infrequently used in the ED setting. This finding was especially notable in race, geographic region, mode of arrival, and those seen by APP, underscoring the need for further study into the root causes of these disparities. Our study provides a foundational understanding of MOUD patterns, guiding future research as the landscape of OUD treatment continues to shift.

Telehealth Use and Health Equity for Mental Health and Substance Use Disorder During the COVID-19 Pandemic: A Systematic Review.

Background: As a result of the COVID-19 public health emergency (PHE), telehealth utilization accelerated to facilitate health care management and minimize risk. However, those with mental health conditions and substance use disorders (SUD)-who represent a vulnerable population, and members of underrepresented minorities (e.g., rural, racial/ethnic minorities, the elderly)-may not benefit from telehealth equally. Objective: To evaluate health equality in clinical effectiveness and utilization measures associated with telehealth for clinical management of mental health disorders and SUD to identify emerging patterns for underrepresented groups stratified by race/ethnicity, gender, age, rural status, insurance, sexual minorities, and social vulnerability. Methods: We performed a systematic review in PubMed, Embase, Cochrane Central Register of Controlled Trials, and CINAHL through November 2022. Studies included those with telehealth, COVID-19, health equity, and mental health or SUD treatment/care concepts. Our outcomes included general clinical measures, mental health or SUD clinical measures, and operational measures. Results: Of the 2,740 studies screened, 25 met eligibility criteria. The majority of studies (n = 20) evaluated telehealth for mental health conditions, while the remaining five studies evaluated telehealth for opioid use disorder/dependence. The most common study outcomes were utilization measures (n = 19) or demographic predictors of telehealth utilization (n = 3). Groups that consistently demonstrated less telehealth utilization during the PHE included rural residents, older populations, and Black/African American minorities. Conclusions: We observed evidence of inequities in telehealth utilization among several underrepresented groups. Future efforts should focus on measuring the contribution of utilization disparities on outcomes and strategies to mitigate disparities in implementation.

Chronic Disease Management through Clinical Video Telehealth on Health Care Utilization, and Mortality in the Veterans Health Administration: A Retrospective Cohort Study.

Background: Chronic health diseases such as congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), and diabetes mellitus (DM) affect 6 in 10 Americans and contribute to 90% of the $4.1 trillion health care expenditures. The objective of this study was to measure the effect of clinical video telehealth (CVT) on health care utilization and mortality. A retrospective cohort study of Veterans ≥65 years with CHF, COPD, or DM was conducted. Measures: Veterans using CVT were matched 1:3 on demographic characteristics to Veterans who did not use CVT. Outcomes included 1-year incidence of ED visits, inpatient admissions, and mortality, reported as adjusted odds ratios (aORs) and 95% confidence intervals (CIs). Results: Final analytical cohorts included 22,280 Veterans with CHF, 51,872 Veterans with COPD, and 170,605 Veterans with DM. CVT utilization was associated with increased ED visits for CHF (aOR: 1.24; 95% CI: 1.15-1.34), COPD (aOR: 1.20; 95% CI: 1.14-1.26), and DM (aOR: 1.07; 95% CI: 1.00-1.10). For CHF, there was no difference between CVT utilization and inpatient admissions (aOR: 0.98; 95% CI 0.91-1.05) or mortality (aOR: 1.03; 95% CI: 0.93-1.15). For COPD, CVT was associated with increased inpatient admissions (aOR: 1.08; 95% CI: 1.02-1.13) and mortality (aOR: 1.36; 95% CI: 1.25-1.48). For DM, CVT utilization was associated with lower risk of inpatient admissions (aOR: 0.83; 95% CI: 0.80-0.86) and mortality (aOR: 0.89; 95% CI: 0.84-0.95). Conclusions: CVT use as an alternative care site might serve as an early warning system, such that this mechanism may indicate when an in-person assessment is needed for potential exacerbation of conditions. Although inpatient and mortality varied, ED utilization was higher with CVT. Exploring pathways accessing clinical care through CVT, and how CVT is directly or indirectly associated with immediate and long-term clinical outcomes would be valuable.

Effect of Chronic Disease Home Telehealth Monitoring in the Veterans Health Administration on Healthcare Utilization and Mortality.

BACKGROUND: The high prevalence of chronic diseases, including congestive heart failure (CHF), chronic obstructive pulmonary disease (COPD), and diabetes mellitus (DM), accounts for a large burden of cost and poor health outcomes in US hospitals, and home telehealth (HT) monitoring has been proposed to improve outcomes. OBJECTIVE: To measure the association between HT initiation and 12-month inpatient hospitalizations, emergency department (ED) visits, and mortality in veterans with CHF, COPD, or DM. DESIGN: Comparative effectiveness matched cohort study. PATIENTS: Veterans aged 65 years and older treated for CHF, COPD, or DM. MAIN MEASURES: We matched veterans initiating HT with veterans with similar demographics who did not use HT (1:3). Our outcome measures included a 12-month risk of inpatient hospitalization, ED visits, and all-cause mortality. KEY RESULTS: A total of 139,790 veterans with CHF, 65,966 with COPD, and 192,633 with DM were included in this study. In the year after HT initiation, the risk of hospitalization was not different in those with CHF (adjusted odds ratio [aOR] 1.01, 95% confidence interval [95%CI] 0.98-1.05) or DM (aOR 1.00, 95%CI 0.97-1.03), but it was higher in those with COPD (aOR 1.15, 95%CI 1.09-1.21). The risk of ED visits was higher among HT users with CHF (aOR 1.09, 95%CI 1.05-1.13), COPD (1.24, 95%CI 1.18-1.31), and DM (aOR 1.03, 95%CI 1.00-1.06). All-cause 12-month mortality was lower in those initiating HT monitoring with CHF (aOR 0.70, 95%CI 0.67-0.73) and DM (aOR 0.79, 95%CI 0.75-0.83), but higher in COPD (aOR 1.08, 95%CI 1.00-1.16). CONCLUSIONS: The initiation of HT was associated with increased ED visits, no change in hospitalizations, and lower all-cause mortality in patients with CHF or DM, while those with COPD had both higher healthcare utilization and all-cause mortality.

Inpatient boarding definitions and mitigation strategies: A cross-sectional survey of academic emergency departments in the United States.

OBJECTIVE: Conceptually, inpatient boarding is a result in the delay of admitting patients from the Emergency Department (ED) to inpatient units, but there is no consistent definition across academic EDs. The purpose of this study was to evaluate the definition of boarding across academic EDs, and to identify mitigation strategies used by EDs to alleviate crowd management. METHODS: This was a cross-sectional survey of boarding-related questions (i.e., boarding definitions and practices) that were embedded into the annual benchmarking survey conducted by the Academy of Academic Administrators of Emergency Medicine and the Association of Academic Chairs of Emergency Medicine. Results were descriptively assessed and tabulated. RESULTS: Of the 130 eligible institutions, 68 participated in the survey. Approximately 70% of institutions reported starting the boarding clock at the time of ED admission, while 19% reported that the clock started with the completion of inpatient orders. Approximately 35% of institutions considered patients boarded within 2 h, while 34% considered patients boarded >4 h after admission decision. In response to ED overcrowding brought on by inpatient boarding, 35% reported using hallway beds for patient care. Surge capacity measures reported included having a high census/surge capacity plan (81%), going on ambulance diversion (54%), and institutional use of a discharge lounge (49%). CONCLUSIONS: We found that definitions for boarding varied widely. Inpatient boarding has serious consequences to patient care and well-being, suggesting the need for standardized definitions to describe inpatient boarding.

Evaluation of Telepsychiatry Services Implementation in Medical and Psychiatric Inpatient Settings: A Mixed-Methods Study.

Introduction: Telepsychiatry consultation for rural providers may help address local staffing needs while ensuring timely and appropriate care from behavioral health experts. The purpose of this study was to assess the implementation of a telepsychiatry consultation service within medical and psychiatry inpatient units of hospitals serving predominantly rural areas. Methods: A mixed-methods study with qualitative interviews of site personnel and quantitative assessment of electronic health record data was conducted across 6 facilities in 3 U.S. states between June 2019 and May 2021. We interviewed 15 health care professionals 6 months after telepsychiatry was implemented, and we identified emerging themes related to the inpatient telepsychiatry service implementation and utilization through an inductive qualitative analysis approach. We then applied the themes emerging from this study to existing implementation science theoretical frameworks. Results: Telepsychiatry consultation was utilized for 437 medical inpatient cases and 531 psychiatric inpatient units. Average encounters by site ranged from 1 to 20 per month. The three main domains from the qualitative assessment included the impact on the care process (the partnership between inpatient units and the telehealth hub, and logistical dynamics), the care provider (resource availability in inpatient units and changes in inpatient units' capability), and the patient (impact on patient safety and care). Discussion: Implementation of a telepsychiatry service in the inpatient setting holds the promise of being beneficial to the patient, local hospital, and the rural community. In this study, we found that implementing this telepsychiatry service improved the clinical care processes, while addressing both the providers' and patients' needs.

Telehealth Utilization Is Associated with Lower Risk of Discontinuation of Buprenorphine: a Retrospective Cohort Study of US Veterans.

OBJECTIVE: Treatment for opioid use disorder (OUD) may include a combination of pharmacotherapies (such as buprenorphine) with counseling services if clinically indicated. Medication management or engagement with in-person counseling services may be hindered by logistical and financial barriers. Telehealth may provide an alternative mechanism for continued engagement. This study aimed to evaluate the association between telehealth encounters and time to discontinuation of buprenorphine treatment when compared to traditional in-person visits and to evaluate potential effect modification by rural-urban designation and in-person and telehealth combination treatment. METHODS: A retrospective cohort study of Veterans diagnosed with OUD and treated with buprenorphine across all facilities within the Veterans Health Administration (VHA) between 2008 and 2017. Exposures were telehealth and in-person encounters for substance use disorder (SUD) and mental health, treated as time-varying covariates. The primary outcome was treatment discontinuation, evaluated as 14 days of absence of medication from initiation through 1 year. RESULTS: Compared to in-person encounters, treatment discontinuation was lower for telehealth for SUD (aHR: 0.69; 95%CI: 0.60, 0.78) and mental health (aHR: 0.69; 95%CI: 0.62, 0.76). There was no evidence of effect modification by rural-urban designation. Risk of treatment discontinuation appeared to be lower among those with telehealth only compared to in-person only for both SUD (aHR: 0.48, 95%CI: 0.37, 0.62) and for mental health (aHR: 0.46; 95%CI: 0.33, 0.65). CONCLUSIONS: As telehealth demonstrated improved treatment retention compared to in-person visits, it may be a suitable option for engagement for patients in OUD management. Efforts to expand services may improve treatment retention and health outcomes for VHA and other health care systems.

Telepsychiatry services across an emergency department network: A mixed methods study of the implementation process.

BACKGROUND: Due to limited community resources for mental health and long travel distances, emergency departments (EDs) serve as the safety net for many rural residents facing crisis mental health care. In 2019, The Leona M. and Harry B. Helmsley Charitable Trust funded a project to establish and implement an ED-based telepsychiatry service for patients with mental health issues in underserved areas. The purpose of this study was to evaluate the implementation of this novel ED-based telepsychiatry service. METHODS: This was a mixed-methods study evaluating the new ED-based telepsychiatry consult service implemented in five EDs across three rural states that participated within a mature hub-and-spoke telemedicine network between June 2019 and December 2020. Quantitative evaluation in this study included characteristics of the telehealth encounters and the patient population for whom this service was used. For qualitative assessments, we identified key themes from interviews with key informants at the ED spokes to assess overall facilitators, barriers, and impact. Integrating the quantitative and qualitative findings, we explored emergent phenomena and identified insights to provide a comprehensive perspective of the implementation process. RESULTS: There were 4130 encounters for 3932 patients from the EDs during the evaluation period. Approximately 54% of encounters involved female patients. The majority of patients seen were white (51%) or Native American (44%) reflecting the population of the communities where the EDs were located. Among the indications for the telepsychiatry consult, the most frequently identified were depression (28%), suicide/self-harm (17%), and schizophrenia (12%). Across sites, 99% of clinician-to-clinician consults were by phone, and 99% of clinical assessments/evaluations were by video. The distribution of encounters varied by the day of the week and the time of day. Facilitators for the service included increasing need, a supportive infrastructure, a straightforward process, familiarity with telemedicine, and a collaborative relationship. Barriers identified by respondents at the sites included the lack of clarity of process and technical limitations. The themes emerging from the impact of the telepsychiatry consultation in the ED included workforce improvement, care improvement, patient satisfaction, cost-benefit, facilitating COVID care, and access improvement. CONCLUSIONS: Implementation of a telepsychiatry service in ED settings may be beneficial to the patient, local ED, and the underserved community. In this study, we found that implementing this service alleviated the burden of care during the COVID-19 pandemic, enhanced local site capability, and improved local ability to provide quality and effective care.

Substance use history is associated with lower opioid use for emergency department pain management.

INTRODUCTION: In the current national opioid crisis, where 10% of the US population has or has had a substance use disorder (SUD), emergency department (ED) clinicians are challenged when treating pain in the ED and when prescribing pain medications to these patients on discharge as there is concern for contributing to the cycle of addiction. The objective of this study was to examine whether acute pain is treated differently in patients with and without current or past SUD by quantifying the amount of opioid analgesia given in the ED and prescribed on discharge. METHODS: Retrospective cohort study of patients presenting to a 60,000-visit tertiary referral ED with acute fracture between January 1, 2016 and June 30, 2019. The primary exposure was indication of SUD (SUD+) versus those without SUD (SUD-). The primary outcome was receipt of opioids in the ED, and the secondary outcome was opioids prescribed at discharge. RESULTS: 117 matched pairs (n = 234) were included in the sample. Overall, 53.4% and 62.4% of patients received opioids in the ED or a prescription for opioids, respectively. Opioid receipt in the ED was lower among SUD+ patients compared to SUD- patients (48.7% and 58.1%, respectively; aOR: 0.33; 95%CI: 0.14, 0.77). Similarly, receipt of a prescription for opioids was lower among SUD+ patients compared to SUD- patients (56.4% and 68.4%, respectively; aOR: 0.50; 95%CI: 0.26, 0.95). CONCLUSIONS: Overall, ED clinicians gave opioids less frequently to SUD+ patients in the ED and on discharge from the ED compared to SUD- patients with acute pain secondary to acute fracture.

Sedation Depth is Associated with Increased Hospital Length of Stay in Mechanically Ventilated Air Medical Transport Patients: A Cohort Study.

Background: Analgesics, sedatives, and neuromuscular blockers are commonly used medications for mechanically ventilated air medical transport patients. Prior research in the emergency department (ED) and intensive care unit (ICU) has demonstrated that depth of sedation is associated with increased mechanical ventilation duration, delirium, increased hospital length-of-stay (LOS), and decreased survival. The objectives of this study were to evaluate current sedation practices in the prehospital setting and to determine the impact on clinical outcomes. Methods: A retrospective cohort study of mechanically ventilated patients transferred by air ambulance to a single 812-bed Midwestern academic medical center from July 2013 to May 2018 was conducted. Prehospital sedation medications and depth of sedation [Richmond Agitation-Sedation Scale score (RASS)] were measured. Primary outcome was hospital LOS. Secondary outcomes were delirium, length of mechanical ventilation, in-hospital mortality, and need for neurosurgical procedures. Univariate analyses were used to measure the association between sedatives, sedation depth, and clinical outcomes. Multivariable models adjusted for potentially confounding covariates to measure the impact of predictors on clinical outcomes. Results: Three hundred twenty-seven patients were included. Among those patients, 79.2% of patients received sedatives, with 41% of these patients achieving deep sedation (RASS = -4). Among patients receiving sedation, 58.3% received at least one dose of benzodiazepines. Moderate and deep sedation was associated with an increase in LOS of 59% (aRR: 1.59; 95% CI: 1.40-1.81) and 24% (aRR: 1.24; 95% CI: 1.10-1.40), respectively. Benzodiazepines were associated with a mean increase of 2.9 days in the hospital (95% CI, 0.7-5.1). No association existed between either specific medications or depth of sedation and the development of delirium. Conclusions: Prehospital moderate and deep sedation, as well as benzodiazepine administration, is associated with increased hospital LOS. Our findings point toward sedation being a modifiable risk factor and suggest an important need for further research of sedation practices in the prehospital setting.

State-level teen dating violence education laws and teen dating violence victimisation in the USA: a cross-sectional analysis of 36 states.

BACKGROUND: Approximately 10% of teens report experiencing sexual dating violence (SDV) or physical dating violence (PDV), collectively represented as teen dating violence (TDV). This study examines the association between laws incorporating TDV education in schools on TDV prevalence. METHODS: TDV prevalence was estimated using data contributed by 36 states that participated in the 2015 Youth Risk Behavioral Surveillance Survey (YRBS). Presence of TDV laws was determined using Westlaw, a legal search engine. The adjusted odds of TDV victimisation was estimated by the presence or absence of a state law and length of time the law was in effect using hierarchical regression modelling, clustering on state, controlling for individual-level and state-level covariates and incorporating the YRBS-weighted survey design. RESULTS: After controlling for individual-level and state-level covariates, the presence of a law was not associated with TDV (adjusted OR (aOR) 0.97; 95% CI 0.88 to 1.06), PDV (aOR 1.12; 95% CI 0.95 to 1.33) or SDV (aOR 0.99; 95% CI 0.91 to 1.08). These odds did not differ across the length of time the policies were in effect. CONCLUSIONS: This study suggest that just the presence of a law incorporating TDV education in schools is not associated with reduced TDV victimisation but further research is needed to understand the association of the content of these laws and their implementation on TDV victimisation.

Central Venous Access Capability and Critical Care Telemedicine Decreases Inter-Hospital Transfer Among Severe Sepsis Patients: A Mixed Methods Design.

OBJECTIVES: Severe sepsis is a complex, resource intensive, and potentially lethal condition and rural patients have worse outcomes than urban patients. Early identification and treatment are important to improving outcomes. The objective of this study was to identify hospital-specific factors associated with inter-hospital transfer. DESIGN: Mixed method study integrating data from a telephone survey and retrospective cohort study of state administrative claims. SETTING AND SUBJECTS: Survey of Iowa emergency department administrators between May 2017 and June 2017 and cohort of adults seen in Iowa emergency departments for severe sepsis and septic shock between January 2005 and December 2013. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Multivariable logistic regression was used to identify independent predictors of inter-hospital transfer. We included 114 institutions that provided data (response rate = 99%), and responses were linked to a total of 150,845 visits for severe sepsis/septic shock. In our adjusted model, having the capability to place central venous catheters or having a subscription to a tele-ICU service was independently associated with lower odds of inter-hospital transfer (adjusted odds ratio, 0.69; 95% CI, 0.54-0.86 and adjusted odds ratio, 0.69; 95% CI, 0.54-0.88, respectively). A facility's participation in a sepsis-specific quality improvement initiative was associated with 62% higher odds of transfer (adjusted odds ratio, 1.62; 95% CI, 1.10-2.39). CONCLUSIONS: The insertion of central venous catheters and access to a critical care physician during sepsis treatment are important capabilities in hospitals that transfer fewer sepsis patients. In the future, hospital-specific capabilities may be used to identify institutions as regional sepsis centers.

Telemedicine Use Decreases Rural Emergency Department Length of Stay for Transferred North Dakota Trauma Patients.

BACKGROUND: Telemedicine has been proposed as one strategy to improve local trauma care and decrease disparities between rural and urban trauma outcomes. OBJECTIVES: This study was conducted to describe the effect of telemedicine on management and clinical outcomes for trauma patients in North Dakota. METHODS: Cohort study of adult (age ≥18 years) trauma patients treated in North Dakota Critical Access Hospital (CAH) Emergency Departments (EDs) from 2008 to 2014. Records were linked to a telemedicine network's call records, indicating whether telemedicine was available and/or used at the institution at the time of the care. Multivariable generalized estimating equations were developed to identify associations between telemedicine consultation and availability and outcomes such as transfer, timeliness of care, trauma imaging, and mortality. RESULTS: Of the 7,500 North Dakota trauma patients seen in CAH, telemedicine was consulted for 11% of patients in telemedicine-capable EDs and 4% of total trauma patients. Telemedicine utilization was independently associated with decreased initial ED length of stay (LOS) (30 min, 95% confidence interval [CI] 14-45 min) for transferred patients. Telemedicine availability was associated with an increase in the probability of interhospital transfer (adjusted odds ratio [aOR] 1.2, 95% CI 1.1-1.4). Telemedicine availability was associated with increased total ED LOS (15 min, 95% CI 10-21 min), and computed tomography scans (aOR 1.6, 95% CI 1.3-1.9). CONCLUSIONS: ED-based telemedicine consultation is requested for the most severely injured rural trauma patients. Telemedicine consultation was associated with more rapid interhospital transfer, and telemedicine availability is associated with increased radiography use and transfer. Future work should evaluate how telemedicine could target patients likely to benefit from telemedicine consultation.

Telemedicine Physical Examination Utilizing a Consumer Device Demonstrates Poor Concordance with In-Person Physical Examination in Emergency Department Patients with Sore Throat: A Prospective Blinded Study.

BACKGROUND: Telemedicine allows patients to connect with healthcare providers remotely. It has recently expanded to evaluate low-acuity illnesses such as pharyngitis by using patients' personal communication devices. The purpose of our study was to compare the telemedicine-facilitated physical examination with an in-person examination in emergency department (ED) patients with sore throat. MATERIALS AND METHODS: This was a prospective, observational, blinded diagnostic concordance study of patients being seen for sore throat in a 60,000-visit Midwestern academic ED. A telemedicine and a face-to-face examination were performed independently by two advanced practice providers (APP), blinded to the results of the other evaluator. The primary outcome was agreement on pharyngeal redness between the evaluators, with secondary outcomes of agreement and inter-rater reliability on 14 other aspects of the pharyngeal physical examination. We also conducted a survey of patients and providers to evaluate perceptions and preferences for sore throat evaluation using telemedicine. RESULTS: Sixty-two patients were enrolled, with a median tonsil size of 1.0. Inter-rater agreement (kappa) for tonsil size was 0.394, which was worse than our predetermined concordance threshold. Other kappa values ranged from 0 to 0.434, and telemedicine was best for detecting abnormal coloration of the palate and tender superficial cervical lymph nodes (anterior structures), but poor for detecting abnormal submandibular lymph nodes or asymmetry of the posterior pharynx (posterior structures). In survey responses, telemedicine was judged easier to use and more comfortable for providers than patients; however, neither patients nor providers preferred in-person to telemedicine evaluation. CONCLUSION: Telemedicine exhibited poor agreement with the in-person physical examination on the primary outcome of tonsil size, but exhibited moderate agreement on coloration of the palate and cervical lymphadenopathy. Future work should better characterize the importance of the physical examination in treatment decisions for patients with sore throat and the use of telemedicine in avoiding in-person healthcare visits.

Epidemiologic Trends in Loperamide Abuse and Misuse.

STUDY OBJECTIVE: Loperamide abuse has been increasing in the United States as a potential alternative to manage opioid withdrawal symptoms or to achieve euphoric effects of opioid use. In June 2016, the Food and Drug Administration warned health care providers and the general public about potential serious adverse outcomes, including cardiac dysrhythmias and death. The purpose of this study is to determine recent trends in intentional loperamide abuse and misuse, reported clinical effects and management, and medical outcomes as reported to poison centers across the United States. METHODS: Loperamide exposures reported to the National Poison Data System indicating intentional misuse, abuse, and suspected suicide between January 1, 2010, and December 31, 2015, were assessed. Demographic and temporal trends, as well as reported clinical effects, medical management, and health outcomes, were analyzed. RESULTS: There was a 91% increase in reported exposures from 2010 to 2015, of which half were single-agent loperamide use only. Loperamide exposures reported to the National Poison Data System increased at approximately 38 cases per year (95% confidence interval [CI] 32.5 to 42.9; P<0.0001). Fifteen deaths were reported during this time frame, of which 8 involved single-agent loperamide abuse. CONCLUSION: Loperamide abuse and misuse are projected to increase in the absence of any methods to reduce exposure or curb abuse. Health care providers should consider the potential for loperamide toxicity when managing patients with opioidlike toxicity.

Negative predictive value of excluding an embedded snake foreign body by ultrasonography.

OBJECTIVE: Numerous reputable sources for healthcare providers advocate routine imaging to rule out an embedded tooth or fang after a snake bite. The objective of this study was to determine whether these foreign bodies can be reliably excluded by bedside ultrasonography. METHODS: All emergency medicine (EM) residents and faculty at a single institution were invited to participate. Two sets of 5 ultrasound gel phantoms were prepared using a method previously validated to have the same density as human tissue. In the first set of 5 phantoms, 1 snake fang was embedded to simulate a retained foreign body. Similarly, in the second set of 5 phantoms, 1 snake tooth was also embedded. Participants were asked to identify the presence or absence of a foreign body in each phantom using bedside ultrasonography. Year of training and confidence in excluding a snake foreign body were also recorded. RESULTS: Each participant (n=27) performed ultrasound imaging on 10 phantoms for a total of 270 samples. Range of experience included postgraduate year 1 (25.9%), postgraduate year 2 (29.6%), postgraduate year 3 (33.3%), and graduates of EM residency (11.1%). The sensitivity and negative predictive value for ruling out an embedded fang was 92.6% and 98.1%, respectively. The sensitivity and negative predictive value for ruling out an embedded tooth was 77.8% and 93.7%, respectively. Among all the phantoms, there was a sensitivity of 85.2% and a negative predictive value of 96%. CONCLUSION: Bedside ultrasonography performed by an EM physician is a feasible option to rule out embedded foreign bodies after a snake bite if imaging is warranted.

Lyme Disease: What the Wilderness Provider Needs to Know.

Lyme disease is a multisystem tickborne illness caused by the spirochete Borrelia burgdorferi and is the most common vectorborne disease in the United States. Prognosis after initiation of appropriate antibiotic therapy is typically good if treated early. Wilderness providers caring for patients who live in or travel to high-incidence Lyme disease areas should be aware of the basic biology, epidemiology, clinical manifestations, and treatment of Lyme disease.

The association between county ordinances allowing off-road vehicles on public roads and crash rates.

BACKGROUND: Legislative bodies across the country have increasingly allowed off-road vehicles (ORVs) including all-terrain vehicles (ATVs) and utility task vehicles (UTVs) on public roads, an environment for which they are not designed. In 2004, Iowa gave individual counties the discretion to pass ordinances allowing ORVs on public roadways. The objective of this study was to evaluate the relationship between the passage of ORV ordinances and ORV crash rates, especially on public roads. METHODS: An Iowa ORV roadway ordinance database and an Iowa ORV crash database (2002-2018) for all 99 counties were compiled. Crashes for which county location could not be determined were excluded. Utilizing a zero-inflated Poisson model, correcting for background crash frequency trends and population, investigators compared the relative rates of crashes after ordinance passage to time points before ordinance implementation and to counties without such ordinances. Sub-analyses, including that focused on more recent years (2008-2018), were also performed. RESULTS: Forty-five county ORV roadway ordinances went into effect between 2011 and 2018 and 2,347 crashes (69%) met inclusion criteria. Adjusted for year, there was a 58% greater ORV crash rate in counties after passing an ORV roadway ordinance (incidence rate ratio (IRR) 1.58, 95% CI 1.32-1.90). Roadway crashes (n = 834) increased 48% after ordinance passage (IRR 1.48, 95% CI 1.14-1.94). This roadway crash association remained statistically significant when analysis was limited to the years 2008-2018 (IRR 1.39, CI 1.06-1.83, n = 544); to ATV crashes only (IRR 1.70, CI 1.20-2.40, n = 683); and to ATV crashes excluding counties with UTV-only ordinances (IRR 1.74, CI 1.40-2.15, n = 2,011). CONCLUSIONS: ORV roadway and total crashes increased significantly after implementation of county ordinances allowing ORVs on public roadways and when compared to counties without such ordinances. It is likely that these increased crashes have resulted in more injuries and possibly deaths. Results from this study may help inform policymakers as they consider legislation regarding ORV usage on public roads.

The role of increasing synchronous telehealth use during the COVID-19 pandemic on disparities in access to healthcare: A systematic review.

INTRODUCTION: The COVID-19 public health emergency led to an unprecedented rapid increase in telehealth use, but the role of telehealth in reducing disparities in access to care has been questioned. The objective of this study was to conduct a systematic review to summarize the available evidence on how telehealth during the COVID-19 pandemic was associated with telehealth utilization for minority groups and its role in health disparities. METHODS: We conducted a systematic review focused on health equity and access to care by searching for interventional and observational studies using the following four search domains: telehealth, COVID-19, health equity, and access to care. We searched PubMed, Embase, Cochrane CENTRAL, CINAHL, telehealth.hhs.gov, and the Rural Health Research Gateway, and included any study that reported quantitative results with a control group. RESULTS: Our initial search yielded 1970 studies, and we included 48 in our final review. The most common dimensions of health equity studied were race/ethnicity, rurality, insurance status, language, and socioeconomic status, and the telehealth applications studied were diverse. Included studies had a moderate risk of bias. In aggregate, most studies reported increased telehealth use during the pandemic, with the greatest increase in non-minority populations, including White, younger, English-speaking people from urban areas. DISCUSSION: We found that despite rapid adoption and increased telehealth use during the public health emergency, telehealth did not reduce existing disparities in access to care. We recommend that future work measuring the impact of telehealth focus on equity so that features of telehealth innovation can reduce disparities in health outcomes.
