The significance of telemedicine in a rural emergency department

Telehealth in emergency medicine: A consensus conference to map the intersection of telehealth and emergency medicine

INTRODUCTION

Telehealth has the potential to significantly change the specialty of emergency medicine (EM) and has rapidly expanded in EM during the COVID pandemic; however, it is unclear how EM should intersect with telehealth. The field lacks a unified research agenda with priorities for scientific questions on telehealth in EM.

METHODS

Through the 2020 Society for Academic Emergency Medicine's annual consensus conference, experts in EM and telehealth created a research agenda for the topic. The multiyear process used a modified Delphi technique to develop research questions related to telehealth in EM. Research questions were excluded from the final research agenda if they did not meet a threshold of at least 80% of votes indicating "important" or "very important."

RESULTS

Round 1 of voting included 94 research questions, expanded to 103 questions in round 2 and refined to 36 questions for the final vote. Consensus occurred with a final set of 24 important research questions spanning five breakout group topics. Each breakout group domain was represented in the final set of questions. Examples of the questions include: "Among underserved populations, what are mechanisms by which disparities in emergency care delivery may be exacerbated or ameliorated by telehealth" (health care access) and "In what situations should the quality and safety of telehealth be compared to in-person care and in what situations should it be compared to no care" (quality and safety).

CONCLUSION

The primary finding from the process was the breadth of gaps in the evidence for telehealth in EM and telehealth in general. Our consensus process identified priority research questions for the use of and evaluation of telehealth in EM to fill the current knowledge gaps. Support should be provided to answer the research questions to guide the evidenced-based development of telehealth in EM.

Addressing Barriers to Telemedicine Use in Rural Emergency Medicine: Leveraging In Situ Simulation

Background: Acute care telemedicine is a critical resource for rural and community Emergency Medicine (EM) providers. To address potential barriers and promote use of these services throughout our health system Emergency Departments (EDs), we embed telemedicine consultations within in situ simulations. Methods: Care teams in health system EDs participated in multidisciplinary in situ simulations that focused on Difficult Airway management or Obstetric Emergencies. Physicians in EM and Neonatology at the referral center were available for assistance via telemedicine consultation. Participants were then surveyed regarding their experience with the telemedicine consultation during the simulations. Results: Participants reported increased likelihood to use telemedicine as well as increased understanding of the technology, awareness of available consultation services, and comfort interacting with the consultant. Conclusions: Embedding telemedicine consultations into in situ EM simulations is an effective approach to address implementation barriers and may promote increased use of telemedicine services among rural and community EM providers.

Telehealth dashboard: leverage reporting functionality to increase awareness of high-acuity emergency department patients across an enterprise practice

BACKGROUND

Emergency Medicine Telehealth (TeleEM) represents an opportunity to work directly with referral centres, rural facilities and underserved areas to mitigate unnecessary testing, optimise resource utilisation and facilitate patient transfers across health systems. To optimise the impact of a TeleEM programme, a tool is needed to remotely monitor patient activity in multiple emergency department facilities, concurrently.

METHODS

After identifying data sources for activation criteria put forth by the TeleEM operations group, rules were constructed within the electronic health record to facilitate data checks and ultimately produce a yes/no response if the category's conditions were met. Responses were organised into a table, with functionality allowing end users to drill into the different sites to see patient-specific information for patients meeting activation criteria.

CONCLUSIONS

The TeleEM dashboard allows for proactive engagement by the TeleEM physician and strengthens the team-based approach of critically ill.

Perceptions and Perceived Utility of Rural Emergency Department Telemedicine Services: A Needs Assessment

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.

Real-time video telemedicine applications in the emergency department: a scoping review of literature

OBJECTIVES

To collect and synthesize the literature describing the use of real-time video-based technologies to provide support in the care of patients presenting to emergency departments.Data SourceSix electronic databases were searched, including Medline, CINAHL, Embase, the Cochrane Database, DARE, and PubMed for all publications since the earliest date available in each database to February 2016.Study SelectionSelected articles were full text articles addressing the use of telemedicine to support patient care in pre-hospital or emergency department settings. The search yielded 2976 articles for review with 11 studies eligible for inclusion after application of the inclusion and exclusion criteria. A scoping review of the selected articles was performed to better understand the different systems in place around the world and the current state of evidence supporting telemedicine use in the emergency department.

CONCLUSIONS

Telemedicine support for emergency department physicians is an application with significant potential but is still lacking evidence supporting improved patient outcomes. Advances in technology, combined with more attractive price-points have resulted in widespread interest and implementation around the world. Applications of this technology that are currently being studied include support for minor treatment centres, patient transfer decision-making, management of acutely ill patients and scheduled teleconsultations.

Use of telehealth in the management of non-critical emergencies in rural or remote emergency departments: A systematic review

BACKGROUND

Telehealth has been used extensively in emergency departments to improve healthcare provision. However, its impact on the management of non-critical emergency presentations within rural and remote emergency department settings has not been adequately explored. The objective of this systematic review is to identify how telehealth has been used to assist in the management of non-critical presentations in rural and remote emergency departments and the outcomes.

METHODS

Articles were identified through database searches of CINAHL, Cochrane, MEDLINE (OVID), Informit and SCOPUS, as well as the screening of relevant article reference and citation lists. To determine how telehealth can assist in the management of non-critical emergencies, information was extracted relating to telehealth programme model, the scope of service and participating health professionals. The outcomes of telehealth programmes were determined by analysing the uptake and usage of telehealth, the impact on altering a diagnosis or management plan as well as patient disposition including patient transfer, discharge, local hospital admission and rates of discharge against medical advice.

RESULTS

Of the 2532 identified records, 15 were found to match the eligibility criteria and were included in the review. Uptake and usage increased for telehealth programmes predominantly utilised by nursing staff with limited local medical support. Teleconsultation conservatively altered patient diagnosis or management in 18-66% of consultations. Although teleconsultation was associated with increased patient transfer rates, unnecessary transfers were reduced. Simultaneously, an increase in local hospital admission was noted and fewer patients were discharged home. Discharge against medical advice rates were low at 0.9-1.1%.

CONCLUSION

The most widely implemented hub-and-spoke telehealth model could be incorporated into existing referral frameworks. Telehealth programmes may assist in reducing unnecessary patient transfer and secondary overtriage, while increasing the capacity of emergency department staff to diagnose and manage patients locally, which may translate into increased local hospital admission and reduced discharge rates following teleconsultation.

The role of telemedicine in pediatric critical care

Telemedicine technologies involve real-time, live, interactive video and audio communication and allow pediatric critical care physicians to have a virtual presence at the bedsides of critically ill children. Telemedicine use is increasing and will be a common in remote emergency departments, inpatient wards, and intensive care units for pediatric care. Hospitals and physicians that use telemedicine technologies provide higher quality of care, are more efficient in resource use with improved cost-effectiveness, and have higher satisfaction among patients, parents, and remote providers. More research will result in improved access to pediatric critical care expertise.

Tele-emergency utilization: In what clinical situations is tele-emergency activated?

INTRODUCTION

Tele-emergency provides audio/visual communication between a central emergency care centre (tele-emergency hub) and a distant emergency department (remote ED) for real-time emergency care consultation. The purpose of this mixed methods study is to examine how often tele-emergency is activated in usual practice and in what circumstances it is used.

METHODS

Tele-emergency log data and merged electronic medical record data from Avera Health (Sioux Falls, SD) were analysed for 60,193 emergency department (ED) encounters presenting over a two-and-a-half year period at 21 critical access hospitals using the tele-emergency service. Of these, tele-emergency was activated for 1512 ED encounters.

RESULTS

Analyses indicated that patients presenting at rural EDs with circulatory, injury, mental and symptoms diagnoses were significantly more likely to have tele-emergency department services activated as were patients who were transferred to another hospital. Interviews conducted with 85 clinicians and administrators at 26 rural hospitals that used this service indicated that this pattern of utilization facilitated rapid transfers and followed recommended clinical protocols for patients needing serious and/or urgent attention (e.g. stroke symptoms, chest pain).

DISCUSSION

Although only used in 3.5% of ED encounters on average, our findings provide evidence that tele-emergency activation is well reasoned and related to those situations when extra expert assistance is particularly beneficial.

Lessons from tele-emergency: improving care quality and health outcomes by expanding support for rural care systems

Tele-emergency services provide immediate and synchronous audio/video connections, most commonly between rural low-volume hospitals and an urban "hub" emergency department. We performed a systematic literature review to identify tele-emergency models and outcomes. We then studied a large tele-emergency service in the upper Midwest. We sent a user survey to all seventy-one hospitals that used the service and received 292 replies. We also conducted telephone interviews and site visits with ninety clinicians and administrators at twenty-nine of these hospitals. Participants reported that tele-emergency improves clinical quality, expands the care team, increases resources during critical events, shortens time to care, improves care coordination, promotes patient-centered care, improves the recruitment of family physicians, and stabilizes the rural hospital patient base. However, inconsistent reimbursement policy, cross-state licensing barriers, and other regulations hinder tele-emergency implementation. New value-based payment systems have the potential to reduce these barriers and accelerate tele-emergency expansion.

The effectiveness of service delivery initiatives at improving patients' waiting times in clinical radiology departments: a systematic review

We reviewed the literature for the impact of service delivery initiatives (SDIs) on patients' waiting times within radiology departments. We searched MEDLINE, EMBASE, CINAHL, INSPEC and The Cochrane Library for relevant articles published between 1995 and February, 2013. The Cochrane EPOC risk of bias tool was used to assess the risk of bias on studies that met specified design criteria. Fifty-seven studies met the inclusion criteria. The types of SDI implemented included extended scope practice (ESP, three studies), quality management (12 studies), productivity-enhancing technologies (PETs, 29 studies), multiple interventions (11 studies), outsourcing and pay-for-performance (one study each). The uncontrolled pre- and post-intervention and the post-intervention designs were used in 54 (95%) of the studies. The reporting quality was poor: many of the studies did not test and/or report the statistical significance of their results. The studies were highly heterogeneous, therefore meta-analysis was inappropriate. The following type of SDIs showed promising results: extended scope practice; quality management methodologies including Six Sigma, Lean methodology, and continuous quality improvement; productivity-enhancing technologies including speech recognition reporting, teleradiology and computerised physician order entry systems. We have suggested improved study design and the mapping of the definitions of patient waiting times in radiology to generic timelines as a starting point for moving towards a situation where it becomes less restrictive to compare and/or pool the results of future studies in a meta-analysis.

Telemedicine in the pediatric intensive care unit

Telemedicine technologies involve real-time, live, interactive video and audio communication and allow pediatric critical care physicians to have a virtual presence at the bedside of any critically ill child. Telemedicine use is increasing and will be a common technology in remote emergency departments, inpatient wards, and pediatric intensive care units. There is mounting data that demonstrate that the use of telemedicine technologies can result in higher quality of care, more efficient resource use and improved cost-effectiveness, and higher satisfaction among patients, parents, and remote providers compared to current models of care.

Cooperative remote video consultation on demand for e-patients

With the advent of high-speed internet band-width consuming video conferencing applications will rapidly become attractive to e-patients seeking real-time video consultations from e-doctors. In a conventional system patients connect to a known server in a medical center of his choice. If the server (i.e. a server via which a medical consultant communicates with a patient) is busy, the patient must wait before the server becomes free. Such a system is not efficient as many patients in medical centers with busy servers may either have to wait long, or are simply turned away. Patients may also leave when they become impatient. Not only the patients suffer due to server unavailability, medical service providers also incur revenue losses due to lost patients. To counter these problems, we propose a distributed cooperative Video Consultation on Demand (VCoD) system where servers are located in many different medical centers in different neighbourhoods close to patient concentrations. In such a cooperative system if patients find their nearby servers under heavy load they are automatically directed to servers that are least loaded by using efficient server selection method (also called anycasting). Simple numerical analysis shows that this not only maximizes revenues for medical service providers by reducing number of lost patients, but also improves average response time for e-patients.

Delivering Diagnostic Quality Video over Mobile Wireless Networks for Telemedicine

In real-time remote diagnosis of emergency medical events, mobility can be enabled by wireless video communications. However, clinical use of this potential advance will depend on definitive and compelling demonstrations of the reliability of diagnostic quality video. Because the medical domain has its own fidelity criteria, it is important to incorporate diagnostic video quality criteria into any video compression system design. To this end, we used flexible algorithms for region-of-interest (ROI) video compression and obtained feedback from medical experts to develop criteria for diagnostically lossless (DL) quality. The design of the system occurred in three steps-measurement of bit rate at which DL quality is achieved through evaluation of videos by medical experts, incorporation of that information into a flexible video encoder through the notion of encoder states, and an encoder state update option based on a built-in quality criterion. Medical experts then evaluated our system for the diagnostic quality of the video, allowing us to verify that it is possible to realize DL quality in the ROI at practical communication data transfer rates, enabling mobile medical assessment over bit-rate limited wireless channels. This work lays the scientific foundation for additional validation through prototyped technology, field testing, and clinical trials.

The value of provider-to-provider telehealth

Telehealth has great potential to improve access to care, but its adoption in routine healthcare has been slow. The lack of clarity about the value of telehealth implementations has been one reason cited for this slow adoption. The Center for Information Technology Leadership has examined the value of telehealth encounters in which there is a provider both with the patient and at a distance from the patient. We considered three models of telehealth: store-and-forward, real-time video, and hybrid systems. Evidence from the literature was extrapolated using a computer simulation, which found that the hybrid model was the most cost effective. The simulation predicted savings of $4.3 billion per year if hybrid telehealth systems were implemented in emergency rooms, prisons, nursing home facilities, and physician offices across the United States. We also conducted a sensitivity analysis to determine which factors most influence costs and savings. Payers, providers, and policymakers should work together to remove the barriers to the adoption of telehealth so that this cost savings can be realized in the U.S. healthcare system.

A Computer Based Telemedicine Protocol to Predict Acute Coronary Syndrome in Patients With Chest Pain at Home

The decision to admit a patient to a coronary care unit for acute coronary syndrome (ACS) has serious medical and financial consequences. In this study, we aimed to develop a computer program to predict the existence of ACS in patients with chest pain at home; it is intended that patients will be able to access the program via the website to test its validity. This study proceeded in two phases. In the first phase, a computer-based decision protocol was developed using recursive-partitioning analysis to predict ACS in 250 patients with chest pain on the basis of their historical data. In the second phase, this protocol was tested in 115 patients for diagnosis of ACS prospectively. Thirty-two of the patients answered the algorithm questions on the website. All of the patients who visited the website of this study were advised to go to the emergency department. Although the algorithm showed the presence of ACS in 82 of 115 patients, 60 of 115 patients were diagnosed as having ACS in the emergency department (n = 55) or at follow-up. The agreement between the diagnosis of the algorithm and the true diagnosis was moderate and statistically significant (Kappa coefficient 0.61, P < 0.001). The sensitivity of the algorithm was 100%, although its specificity was 60%. The accuracy of the algorithm in diagnosing ACS was 81%. The algorithm diagnoses patients with ACS at a high ratio and decreases the number of patients being unnecessarily admitted to the emergency with non-ACS.

A simple and low-cost Internet-based teleconsultation system that could effectively solve the health care access problems in underserved areas of developing countries

In many developing countries including Turkey, telemedicine systems are not in wide use due to the high cost and complexity of the required technology. Lack of these systems however has serious implications on patients who live in rural areas. The objective of this paper is to present a simple and economically affordable alternative to the current systems that would allow experts to easily access the medical data of their remote patients over the Internet. The system is developed in client-server architecture with a user-friendly graphical interface and various services are implemented as dynamic web pages based on PHP. The other key features of the system are its powerful security features and platform independency. An academic prototype is implemented and presented to the evaluation of a group of physicians. The results reveal that the system could find acceptance from the medical community and it could be an effective means of providing quality health care in developing countries.
