Thinnes R, Swanson MB, Wetjen K, Harland KK, Mohr NM. Preferences for emergency medical service transport after childhood injury: An emergency department-based multi-methods study. Injury 2020; 51:1961-1969. [PMID: 32507453 PMCID: PMC7508417 DOI: 10.1016/j.injury.2020.04.036] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2020] [Revised: 04/09/2020] [Accepted: 04/24/2020] [Indexed: 02/02/2023]
Abstract
BACKGROUND Pre-hospital emergency medical services (EMS) transport can be associated with benefits following pediatric injury. However, many pediatric trauma patients do not use EMS. The objective of this study was to elucidate guardians' decision factors for pre-hospital transport for children after injury. METHODS This is a multi-methods study of pediatric trauma patients (≤14 years) and their guardians presenting to the ED of a Level I Pediatric Trauma Center via both EMS and non-EMS modalities. Demographic information and injury characteristics were collected. Semi-structured interviews were conducted, and qualitative codes were identified and assigned into themes. RESULTS (Quantitative): Of the 29 child-guardian pairs, five participants initially presented by EMS, 18 were admitted, and the majority (66%) sustained mild injuries. Guardians' assessment of their child's injury severity did not correlate with Injury Severity Score (ISS). Neither EMS status (did or did not use EMS to transport to first hospital) nor rurality status of participants' place of residence were associated with disparate management in any of the three scenarios. (QUALITATIVE) Five themes emerged, which informed guardians' transport decisions: Factors Related to the Nature of the Patient's Injury, Guardian Attributes and Prior Experiences, Access and Availability of EMS, Perceived Risks and Benefits of EMS and Hospital, and Collaborative Decision-Making. Injury characteristics and contextual factors, like perceived EMS response times and advice from family or medical providers, were considered in choices about EMS utilization and hospital selection. Despite the view that EMS response times were important in determining what to do following injury, both EMS and non-EMS users were largely unfamiliar with the capabilities of EMS in their area. Finally, guardians described cost to be a theoretical risk of EMS use, and a few cited this as a factor contributing to their decision-making. CONCLUSIONS Guardians used a variety of considerations to make transport decisions, including the five themes identified above. Future studies could explore modalities to disseminate information about pre-hospital decision-making for guardians and determine the relationship between EMS utilization and patient outcomes.

Abstract
Objective: This analysis identified the rate of transfers and averted transfers and their associated costs across multiple emergency department telemedicine (teleED) networks. Methods: This study is a prospective cohort analysis in six teleED networks operating in 65 hospitals in 11 states across the United States. Each submitted uniform data on all teleED encounters for a 26-month period to a data co-ordinating center. Averted transfers were identified if an encounter met specific criteria. Cost savings from averted transfers were estimated from hospital-specific costs of transferred patients. Results: A total of 4,324 teleED encounters were reported. Excluding patients who died, 1,934 (46.2%) were transferred to another inpatient facility. Records of the remaining 2,248 teleED patients were examined and 882 (39.2% of nontransfers; 20.4% of all teleED cases) teleED patients met the criteria for an averted transfer. Of the averted transfer cases, 53.3% were admitted to the local inpatient facility, and 43.5% were discharged. Patients who averted transfer had lower levels of severity and less billed services than those who were transferred. Transport savings for averted transfers were estimated to total $1,074,663 annually across the six teleED networks. Average estimated transport savings were $2,673 for each averted transfer. Conclusions: In a large cohort of teleED cases, 39% of nontransfer cases were averted transfers (20% of all teleED cases). Importantly, 43% of these patients were routinely discharged rather than being transferred. Averted transfers saved on average $2,673 in avoidable transport costs per patient, with 63.6% of these cost savings accruing to public insurance.

Abstract
PURPOSE Early recognition and prompt prehospital care is a cornerstone of acute stroke treatment. Residents of rural areas have worse access to stroke services than urban residents. The purpose of this study was to (1) describe US trends in rural-urban stroke mortality and (2) identify possible factors associated with rural-urban stroke case-fatality disparities. METHODS This study was a nationwide retrospective cohort study of stroke admissions. The primary exposure was rurality of patient's residence. The primary outcome was death during hospital encounter. The secondary outcome was discharge to a care facility or home healthcare. Univariable and multivariable logistic regressions estimated the odds of mortality by subject rurality among stroke subjects. FINDINGS Rural stroke subjects had higher mortality than nonrural counterparts (18.6% rural vs 16.9% nonrural). After adjustment for patient and hospital factors, patient rurality was associated with increased odds of mortality (aOR = 1.11; 95% CI: 1.06-1.15; P < .001). For the secondary outcome of discharge to home, rural stroke subjects were less likely to be discharged to a care facility than nonrural stroke visits (aOR 0.94; 95% CI: 0.91-0.97; P < .001). Results were similar after adjusting for thrombolytics administration and transfer status. CONCLUSIONS Rural stroke patients have higher mortality than their urban counterparts likely due to their increased burden of chronic disease, lower health literacy, and reduced access to prompt prehospital care. There may be an opportunity for emergency medical services systems to assist in increasing stroke awareness for both patients and clinicians and to establish response patterns to expedite emergency care.

Abstract
OBJECTIVES Emergency department boarding is the practice of caring for admitted patients in the emergency department after hospital admission, and boarding has been a growing problem in the United States. Boarding of the critically ill has achieved specific attention because of its association with poor clinical outcomes. Accordingly, the Society of Critical Care Medicine and the American College of Emergency Physicians convened a Task Force to understand the implications of emergency department boarding of the critically ill. The objective of this article is to review the U.S. literature on (1) the frequency of emergency department boarding among the critically ill, (2) the outcomes associated with critical care patient boarding, and (3) local strategies developed to mitigate the impact of emergency department critical care boarding on patient outcomes. DATA SOURCES AND STUDY SELECTION Review article. DATA EXTRACTION AND DATA SYNTHESIS Emergency department-based boarding of the critically ill patient is common, but no nationally representative frequency estimates has been reported. Boarding literature is limited by variation in the definitions used for boarding and variation in the facilities studied (boarding ranges from 2% to 88% of ICU admissions). Prolonged boarding in the emergency department has been associated with longer duration of mechanical ventilation, longer ICU and hospital length of stay, and higher mortality. Health systems have developed multiple mitigation strategies to address emergency department boarding of critically ill patients, including emergency department-based interventions, hospital-based interventions, and emergency department-based resuscitation care units. CONCLUSIONS Emergency department boarding of critically ill patients was common and was associated with worse clinical outcomes. Health systems have generated a number of strategies to mitigate these effects. A definition for emergency department boarding is proposed. Future work should establish formal criteria for analysis and benchmarking of emergency department-based boarding overall, with subsequent efforts focused on developing and reporting innovative strategies that improve clinical outcomes of critically ill patients boarded in the emergency department.

Abstract
Introduction Interfacility transfers from rural emergency departments (EDs) are an important means of access to timely and specialized care. Methods Our goal was to identify and explore facilitators and barriers in transfer processes and their implications for emergency rural care and access. Semi-structured interviews with ED staff at five rural and two urban Veterans Health Administration (VHA) hospitals were recorded, transcribed, coded, and analyzed using an iterative inductive-deductive approach to identify themes and construct a conceptual framework. Results From 81 interviews with clinical and administrative staff between March–June 2018, four themes in the interfacility transfer process emerged: 1) patient factors; 2) system resources; and 3) processes and communication for transfers, which culminate in 4) the location decision. Current and anticipated resource limitations were highly influential in transfer processes, which were described as burdensome and diverting resources from clinical care for emergency patients. Location decision was highly influenced by complexity of the transfer process, while perceived quality at the receiving location or patient preferences were not reported in interviews as being primary drivers of location decision. Transfers were described as burdensome for patients and their families. Finally, patients with mental health conditions epitomized challenges of emergency transfers. Conclusion Interfacility transfers from rural EDs are multifaceted, resource-driven processes that require complex coordination. Anticipated resource needs and the transfer process itself are important determinants in the location decision, while quality of care or patient preferences were not reported as key determinants by interviewees. These findings identify potential benefits from tracking transfer boarding as an operational measure, directed feedback regarding outcomes of transferred patients, and simplified transfer processes.

Abstract
Background: The low volume and the intermittent nature of serious emergencies presenting to rural emergency departments (EDs) make it difficult to plan and deliver pertinent professional training. Telemedicine provides multiple avenues for training rural ED clinicians. This study examines how telemedicine contributes to professional training in rural EDs through both structured and unstructured approaches. Methods: This qualitative study examined training experiences in 18 hospitals located in 6 Midwest states in the United States, which participated in a single hub-and-spoke telemedicine network. Twenty-eight interviews were conducted with 7 physicians, 10 advanced practice providers, and 11 nurses. Standard, inductive qualitative analysis was used to identify key themes related to experiences with telemedicine-based training and its impact on rural ED practice. Results: For structured formal training, rural ED clinicians used asynchronous sessions more often than live sessions. It was reported that the formal training program may not have been fully utilized due to time and workload constraints. Rural clinicians strongly valued unstructured real-time training during telemedicine consultations. It was perceived consistently across professional groups that real-time training occurred frequently and its spontaneous nature was beneficial. Hub providers offering suggestions respectfully and explaining the rationale behind recommendations facilitated real-time learning. Rural providers and nurses perceived several effects of real-time training, including keeping rural practice up to date, instilling confidence, and improving performance. Discussion: Our research shows that telemedicine provided rural ED providers and nurses both formal training and real-time training opportunities. Real-time training occurred frequently, complemented formal training, and was perceived to have many advantages.

Abstract
Introduction: Acute myocardial infarction (AMI) is a time-sensitive condition. Meeting guideline-recommended time metrics for these patients can be challenging in rural emergency departments (EDs). Telemedicine has been shown to improve the quality and timeliness of emergency care in rural areas. The objective of this study was to evaluate the impact of telemedicine on the timeliness of emergency AMI care for patients presenting to rural EDs with chest pain. Methods: A prospective cohort study, conducted in six telemedicine networks, identified ED patients presenting with chest pain from November 2015 through December 2017. Primary exposure was telemedicine consultation during the ED visit. The primary outcome was time-to-electrocardiogram (ECG). For eligible AMI patients, secondary outcomes included: (1) fibrinolysis administered and (2) time-to-fibrinolysis. Analyses for multivariable models were conducted by using logistic regression, clustered at the hospital level. Results: Overall, 1,220 patients presenting with chest pain were included in the study cohort (27.1% received telemedicine). Time-to-ECG was, on average, 0.39 times (95% confidence interval [CI] -0.26 to -0.52) faster for telemedicine cases. Among eligible patients, telemedicine was associated with higher odds of fibrinolysis administration (adjusted odds ratio 7.17, 95% CI 2.48-20.49). In a sensitivity analysis excluding patients with cardiac arrest, time-to-fibrinolysis administration did not differ when telemedicine was used. Discussion: In telemedicine networks, telemedicine consultation during the ED visit was associated with improved timeliness of ECG evaluation and increased use of fibrinolytic reperfusion therapy for rural AMI patients. Future work should focus on the impact of telemedicine consultation on patient-centered outcomes.

Abstract
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.

Abstract
BACKGROUND Inter-facility transfer is an important strategy for improving access to specialized health services, but transfers are complicated by over-triage, under-triage, travel burdens, and costs. The purpose of this study is to describe ED-based inter-facility transfer practices within the Veterans Health Administration (VHA) and to estimate the proportion of potentially avoidable transfers. METHODS This observational cohort study included all patients treated in VHA EDs between 2012 and 2014 who were transferred to another VHA hospital. Potentially avoidable transfers were defined as patients who were either discharged from the receiving ED or admitted to the receiving hospital for ≤1 day without having an invasive procedure performed. We conducted facility- and diagnosis-level analyses to identify subgroups of patients for whom potentially avoidable transfers had increased prevalence. RESULTS Of 6,173,189 ED visits during the 3-year study period, 18,852 (0.3%) were transferred from one VHA ED to another VHA facility. Rural residents were transferred three times as often as urban residents (0.6% vs. 0.2%, p < 0.001), and 22.8% of all VHA-to-VHA transfers were potentially avoidable transfers. The 3 disease categories most commonly associated with inter-facility transfer were mental health (34%), cardiac (12%), and digestive diagnoses (9%). CONCLUSIONS VHA inter-facility transfer is commonly performed for mental health and cardiac evaluation, particularly for patients in rural settings. The proportion that are potentially avoidable is small. Future work should focus on improving capabilities to provide specialty evaluation locally for these conditions, possibly using telehealth solutions.

Abstract
INTRODUCTION Sepsis is a life-threatening emergency. Together, early recognition and intervention decreases mortality. Protocol-based resuscitation in the emergency department (ED) has improved survival in sepsis patients, but guideline-adherent care is less common in low-volume EDs. This study examined the association between provider-to-provider telemedicine and adherence with sepsis bundle components in rural community hospitals. METHODS This is a prospective cohort study of adults presenting with sepsis or septic shock in community EDs participating in rural telemedicine networks. The primary outcome was adherence to four sepsis bundle requirements: lactate measurement within 3 hours, blood culture before antibiotics, broad-spectrum antibiotics, and adequate fluid resuscitation. Multivariable generalized estimating equations estimated the association between telemedicine and adherence. RESULTS In this cohort (n = 655), 5.6% of subjects received ED telemedicine consults. The telemedicine group was more likely to be male and have a higher severity of illness. After adjusting for severity and chief complaint, total sepsis bundle adherence was higher in the telemedicine group compared with the non-telemedicine group (aOR 17.27 [95%CI 6.64-44.90], p < 0.001). Telemedicine consultation was associated with higher adherence with three of the individual bundle components: lactate, antibiotics, and fluid resuscitation. DISCUSSION Telemedicine patients were more likely to receive initial blood lactate measurement, timely broad-spectrum antibiotics, and adequate fluid resuscitation. In rural, community EDs, telemedicine may improve sepsis care and potentially reduce disparities in sepsis outcomes at low-volume facilities. Future work should identify specific components of telemedicine-augmented care that improve performance with sepsis quality indicators.

Abstract
OBJECTIVE Delirium is acute disorder of attention and cognition. We conducted an observational study using a hospital-wide database to validate three delirium prediction models that were developed to predict prevalent delirium within the first day of hospitalization after ED visit. METHODS This was a retrospective cohort study at the academic medical center to evaluate the predictive ability of three previously developed prediction models for delirium from 2014 to 2017. We included patients aged 65 years and older who were hospitalized from ED. Nurses used the Delirium Observation Screening Scale (DOSS) twice daily while hospitalized. We extracted variables to examine the three prediction models with a positive DOSS screen within the first day of admission. The predictive ability was summarized using the area under the curve (AUC). RESULTS We identified 2582 visits with a positive DOSS screen and 877 visits with a diagnosis of delirium from ICD9/10 codes among 12,082 encounters. The AUC of these prediction models ranged from 0.71 to 0.80 when predicting a positive DOSS screen, and 0.68 to 0.72 when predicting a ICD9/10 diagnosis of delirium. In our cohort, the delirium risk score which uses the cutoff of positive or negative predicted DOSS positive delirium with the AUC of 0.8 (p < .0001). The model demonstrated the sensitivity and the specificity of 91.2 (95% CI 90.0-92.3) and 50.3 (95% CI 49.3-51.3). CONCLUSION In this study, the delirium risk score had the highest predictive ability for prevalent delirium defined by a positive DOSS within the first day of hospitalization.

Abstract
INTRODUCTION Telemedicine can improve access to emergency stroke care in rural areas, but the benefit of telemedicine across different types and models of telemedicine networks is unknown. The objectives of this study were to (a) identify the impact of telemedicine on emergency department (ED) stroke care, (b) identify if telemedicine impact varied by network and (c) describe the variation in process outcomes by telemedicine across EDs. METHODS A prospective cohort study identified stroke patients in four telemedicine networks between November 2015 and December 2017. Primary exposure was telemedicine consultation during ED evaluation. Outcomes included: (a) interpretation of computed tomography (CT) of the head within 45 minutes and (b) time to administer tissue plasminogen activator (tPA). An interaction term tested for differences in telemedicine effect on stroke care by network and hospital. RESULTS Of the 932 stroke subjects, 36% received telemedicine consults. For subjects with a last known well time within two hours of ED arrival (27.9%), recommended CT interpretation within 45 minutes was met for 66.8%. Telemedicine was associated with higher odds of timely head CT interpretation (adjusted odds ratio = 3.03; 95% confidence interval (CI) 1.69-5.46). The magnitude of the association between telemedicine and time to interpret a CT of the head differed between telemedicine networks (interaction term p = 0.033). Among eligible patients, telemedicine was associated with faster time to administer tPA (adjusted hazard ratio = 1.81; 95% CI 1.31-2.50). DISCUSSION Telemedicine consultation during the ED encounter decreased the time to interpret at CT of the head among stroke patients, with differing magnitudes of benefit across telemedicine networks. The effect of heterogeneity of telestroke affects across different networks should be explored in future analyses.

Abstract
OBJECTIVE The purpose of this study was to evaluate the impact of telemedicine in clinical management and patient outcomes of patients presenting to rural critical access hospital emergency departments (EDs) with suicidal ideation or attempt. METHODS Retrospective propensity-matched cohort study of patients treated for suicidal attempt and ideation in 13 rural critical access hospital EDs participating in a telemedicine network. Patients for whom telemedicine was used were matched 1:1 to those who did not have telemedicine as an exposure (n=139 TM+, n=139 TM-) using optimal matching of propensity scores based on administrative data. Our primary outcome was ED length-of-stay (LOS), and secondary outcomes included admission proportion, use of chemical or physical restraint, 30 day ED return, involuntary detention orders, treatment/follow-up plan and 6-month mortality. Analyses for multivariable models were conducted using conditional linear and logistic regression clustered on matched pairs with purposeful selection of covariates. RESULTS Mean ED LOS was not associated with telemedicine consultation among all patients, but was associated with a 29.3% decrease in transferred patients (95% CI 11.1 to 47.5). The adjusted odds of hospital admission (either local or through transfer) was 2.35 (95% CI 1.10 to 5.00) times greater among TM+ patients compared with TM- patients. Involuntary hold placement was lower in those exposed to telemedicine (adjusted odds ratio (aOR): 0.48; 95% CI 0.23 to 0.97). We did not observe significant differences in other outcomes. CONCLUSION The role of telemedicine in influencing access, quality and efficiency of care in underserved rural hospitals is critically important as these networks become more prevalent in rural healthcare environments.

Abstract
INTRODUCTION Awareness with paralysis is a complication with potentially devastating psychological consequences for mechanically ventilated patients. While rigorous investigation into awareness has occurred for operating room patients, little attention has been paid outside of this domain. Mechanically ventilated patients in the emergency department (ED) have been historically managed in a way that predisposes them to awareness events: high incidence of neuromuscular blockade use, underdosing of analgesia and sedation, delayed administration of analgesia and sedation after intubation, and a lack of monitoring of sedation targets and depth. These practice patterns are discordant to recommendations for reducing the incidence of awareness, suggesting there is significant rationale to examine awareness in the ED population. METHODS AND ANALYSIS This is a single centre, prospective cohort study examining the incidence of awareness in mechanically ventilated ED patients. A cohort of 383 mechanically ventilated ED patients will be included. The primary outcome is awareness with paralysis. Qualitative reports of all awareness events will be provided. Recognising the potential problem with conventional multivariable analysis arising from a small number of events (expected less than 10-phenomenon of separation), Firth penalised method, exact logistic regression model or penalised maximum likelihood estimation shrinkage (Ridge, LASSO) will be used to assess for predictors of awareness. ETHICS AND DISSEMINATION Approval of the study by the Human Research Protection Office has been obtained. This work will be disseminated by publication of peer-reviewed manuscripts, presentation in abstract form at scientific meetings and data sharing with other investigators through academically established means.

Abstract
Background: Access to specialized medical care is often limited in rural emergency departments (EDs). Specialist consultation through telemedicine services could help increase access in low-resource areas. Introduction: The objective of this study was to better understand providers' perceptions of the anticipated impact of telemedicine in rural Midwestern EDs. The secondary objective was to understand differences in the perception of rural and academic providers in their views of the utility of telemedicine. Materials and Methods: We conducted a survey of medical providers including physicians, physician assistants, and nurse practitioners at five rural Midwestern critical access hospitals and within six departments at a university medical center in the same region. The survey addressed opinions on telemedicine, including how often it would be used and the potential to improve patient care and reduce transfers. Results: Specialties of high perceived utility to rural providers include psychiatry, cardiology, and neurology; whereas academic providers viewed services in psychiatry, pediatric critical care, and neurology to be of the most potential value. Academic and rural providers have differing opinions on the anticipated frequency of telemedicine use (p < 0.001) and prevention of inter-hospital transfers (p = 0.023). There were significant differences in perceived value by specialty. Conclusion: There is a high demand for telemedicine consultation services in rural Midwestern hospitals, particularly in psychiatry, cardiology, and neurology. Overall, academic providers view telemedicine services as more valuable within their specialty than do rural providers. Further research should be done to investigate individualization of telehealth services based on regional needs and how disparate opinions predict telemedicine utilization.

Concurrent Proximal Fractures Are Rare in Distal Forearm Fractures: A National Cross-sectional Study. West J Emerg Med 2019; 20:747-759. [PMID: 31539332 PMCID: PMC6754191 DOI: 10.5811/westjem.2019.5.42952] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2019] [Revised: 08/06/2019] [Accepted: 05/30/2019] [Indexed: 11/18/2022] Open
Abstract
INTRODUCTION Distal forearm fractures (DFF) account for 1.5% of emergency department (ED) visits in the United States. Clinicians frequently obtain imaging above/below the location of injury to rule out additional injuries. We sought to determine the incidence of associated proximal fractures (APF) in the setting of DFF and to evaluate the imaging practices in a nationally representative sample of EDs. METHODS We queried the 2013 National Emergency Department Sample using International Classification of Diseases, 9th edition, diagnostic codes for DFF and APF. Current Procedural Technology codes identified associated imaging studies. We calculated national estimates using a weighted analysis of patient and hospital-level characteristics associated with APF and imaging practices. An analysis of costs estimated the financial impact of additional imaging in patients with DFF using Medicare reimbursement to approximate costs according to the 2018 Medicare Physician Fee Schedule. RESULTS In 2013, an estimated 297,755 ED visits (weighted) were associated with a DFF, of which 1.6% (4836 cases) had an APF. The incidence of APF was lower among females (odds ratio [OR] (0.76); 95% confidence interval [CI], 0.64-0.91) but higher in metropolitan teaching hospitals compared to metropolitan non-teaching hospitals (OR [2.39]; 95% CI, 1.43-3.99) and Level 1 trauma centers (OR [3.9]; 95%, 1.91-7.96) compared to non-trauma centers. Approximately 40% (n = 117,948) of those with only DFF received non-wrist radiographs and 19% (n = 55,236) underwent non-wrist/non-forearm imaging. Factors independently associated with additional imaging included gender, payer, patient and hospital rurality, hospital region, teaching status, ownership, and trauma center level. Nearly $3.6 million (2018 U.S. dollars) was spent on the aforementioned additional imaging. CONCLUSION Despite the frequency of proximal imaging in patients with DFF, the incidence of APF was low. Further study to identify risk factors for APF based on mechanism and physical examination factors may result in reduced imaging and decreased avoidable healthcare spending.

The Association Between Telemedicine and Emergency Department (ED) Disposition: A Stepped Wedge Design of an ED-Based Telemedicine Program in Critical Access Hospitals. J Rural Health 2019; 36:360-370. [PMID: 31013552 DOI: 10.1111/jrh.12370] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2018] [Revised: 02/17/2019] [Accepted: 03/11/2019] [Indexed: 11/29/2022]
Abstract
PURPOSE To study the relationship between the availability and activation of emergency department-based telemedicine (teleED) and patient disposition in Critical Access Hospitals (CAHs). METHODS A non randomized stepped wedge design examined 133,396 ED visits in 15 CAHs that subscribe to a single teleED provider. Data were available for at least 12 months prior to teleED implementation and at least 12 months of post-implementation. Primary analyses were conducted using multinomial logistic regression models with teleED availability (indicator of post-teleED implementation period) and activation (indicator of utilization of teleED service) predicting discharge disposition adjusting for age, sex, and clinical diagnosis. RESULTS Patients for whom teleED was activated were more likely to be transferred [adjusted odds ratio (aOR) = 12.04; 95% confidence interval (CI), 10.97-13.21] and more likely to be admitted to the local hospital (aOR = 3.23; 95% CI, 2.84-3.67) than to be routinely discharged. This pattern was confirmed for patients presenting with chest pain, mental illness, and injury/poisoning. However, in the period following teleED implementation, patients presenting to EDs after telemedicine was available, but not necessarily utilized, were less likely to be admitted to the local hospital (aOR = 0.79; 95% CI, 0.76-0.82) than to be routinely discharged. CONCLUSIONS Telemedicine availability in CAH EDs is associated with a higher likelihood of routine discharges from the ED possibly due to changes in care associated with teleED implementation. The relationship between teleED use and disposition may be related to selection in activating teleED for cases more likely to require hospital inpatient care.

Abstract
PURPOSE This study aimed to describe the care provide by Emergency Medical Services (EMS) to severe sepsis patients being transferred between acute care hospitals and identify how that care contributes to sepsis care goals. METHODS This was a single-center retrospective cohort study conducted at a 60,000-visit Midwestern academic emergency department, using run reports from 13 ambulance services transferring from 9 hospitals. RESULTS 39 patients were included in the final cohort, transferred by 13 ambulance services from 9 hospitals. Included patients were adults with severe sepsis transferred by ambulance between 2009 and 2014. Thirty-nine patients were included in this cohort. 41% (n = 12) of patients received an adequate fluid bolus of 30 mL/kg (median 42.9 mL/kg crystalloid fluid, IQR 8.0 mL/kg) prior to tertiary care arrival. Seventeen percent (n = 2) of patients completed the adequate bolus during transfer time. Broad-spectrum antibiotics were initiated during transfer in 2 patients. CONCLUSIONS EMS sepsis care during transfer was limited. EMS crews primarily continued treatments previously initiated and did not take additional steps toward resuscitation targets. Data suggests the inter-emergency department transfer period may provide an opportunity to continue working toward treatment targets, though the time is currently underutilized.

Abstract
Introduction Procedural sedation and analgesia (PSA) provides safe and effective relief for pain, anxiety and discomfort during procedures performed in the emergency department (ED). Our objective was to identify hospital-level factors associated with routine PSA capnography use in the ED. Methods This study was a cross-sectional telephone survey of ED nurse managers and designees in a Midwestern state. Respondents identified information about hospital infrastructure, physician staffing, family practice (FP) physicians only, board-certified emergency physicians (EPs) only (or both), and critical intervention capabilities. Additional characteristics including ED volume and hospital designation (i.e., rural-urban classification) were obtained from the Centers for Medicare and Medicaid Services and the state hospital association database, respectively. The primary outcome was reported use of PSA capnography. We conducted univariate analyses (relative risks, 95% confidence interval [CI]) to identify associations between hospital-level characteristics and PSA capnography use. Results We had an overall response rate of 98% (n=118 participating hospitals). The majority of EDs were in rural settings (78%), with a median of 5,057 visits per year (interquartile range 2,823-14,322). Nearly half of the EDs were staffed by FP physicians only, while 16% had board-certified EPs only. Nearly all hospitals (n=114, 97%), reported using continuous capnography for ventilated patients, and 74% reported use of capnography during PSA. Urban hospitals were more likely to use PSA capnography than critical access hospitals (relative risk 1.45; 95% CI, 1.22-1.73), and PSA capnography use increased with each ED volume quartile. Facilities with only EPs were 1.46 (95% CI, 1.15-1.87) times more likely to use PSA capnography than facilities with FP physicians only. Conclusion Continuous capnography was available in nearly all EDs, independent of size, location or patient volume. The implementation of capnography during PSA was less penetrant. Smaller, rural departments were less likely than their larger, urban counterparts to implement these national guidelines. Rurality and hospital size may be potential institutional barriers to capnography implementation.

Abstract
Health informatics is a vital technology that holds great promise in the healthcare setting. We describe two prominent health informatics tools relevant to emergency care, as well as the historical background and the current state of informatics. We also identify recent research findings and practice changes. The recent advances in machine learning and natural language processing (NLP) are a prominent development in health informatics overall and relevant in emergency medicine (EM). A basic comprehension of machine-learning algorithms is the key to understand the recent usage of artificial intelligence in healthcare. We are using NLP more in clinical use for documentation. NLP has started to be used in research to identify clinically important diseases and conditions. Health informatics has the potential to benefit both healthcare providers and patients. We cover two powerful tools from health informatics for EM clinicians and researchers by describing the previous successes and challenges and conclude with their implications to emergency care.

Abstract
INTRODUCTION In mechanically ventilated patients, sedation strategies are a major determinant of outcome. The emergency department (ED) is the earliest exposure to mechanical ventilation for hundreds of thousands of patients annually in the USA. The one retrospective study that exists regarding ED sedation for mechanically ventilated patients showed a strong association between deep sedation in the ED and worse clinical outcomes. This finding suggests that the ED may be an optimal location to study the impact of early sedation on outcome, yet a lack of prospective studies represents a knowledge gap in this arena. This protocol describes a prospective observational study aimed at further characterising ED sedation practices and assessing the relationship between ED sedation and clinical outcomes. An association between ED sedation and clinical outcomes across multiple sites would suggest the need for changes in the current sedation strategies used in the ED, and provide evidence for future interventional studies in this field. METHODS AND ANALYSIS This is a multicentre, prospective cohort study testing the hypothesis that deep sedation in the ED is associated with worse clinical outcomes. A cohort of over 300 mechanically ventilated ED patients will be included. The primary outcome is ventilator-free days, and secondary outcomes include hospital mortality, incidence of acute brain dysfunction and lengths of stay. Multivariable linear regression will test the hypothesis that deep sedation in the ED is associated with a decrease in ventilator-free days. ETHICS AND DISSEMINATION Approval of the study by the Institutional Review Board (IRB) at each participating site has been obtained prior to data collection on the first patient. This work will be disseminated by publication of peer-reviewed manuscripts, presentation in abstract form at scientific meetings and data sharing with other investigators through academically established means.

Abstract
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.
