Predicted utilization of emergency medical services telemedicine in decreasing ambulance transports

Clinician and Caregiver Determinations of Acuity for Children Transported by Emergency Medical Services: A Prospective Observational Study

STUDY OBJECTIVE

Many Emergency Medical Services (EMS) agencies have developed alternative disposition processes for patients with nonemergency problems, but there is a lack of evidence demonstrating EMS clinicians can accurately determine acuity in pediatric patients. Our study objective was to determine EMS and other stakeholders' ability to identify low acuity pediatric EMS patients.

METHODS

We conducted a prospective, observational study of children transported to a pediatric emergency department (ED) by EMS. Acuity was defined using a composite measure that included data from the patient's vital signs and examination, resources used (laboratory results, radiographs, etc), and disposition. For each patient, an EMS clinician, patient caregiver, ED nurse, and ED provider completed a survey as soon as possible after the patient's arrival at the ED. The survey asked respondents 2 questions: to state their level of agreement that a patient was low acuity and could the patient have been managed by various alternative dispositions. For each respondent group, we calculated the sensitivity, specificity, and positive and negative predictive values for low acuity versus the composite measure.

RESULTS

From August 2020 through September 2021, we approached 1,015 caregivers, of whom 996 (99.8%) agreed to participate and completed the survey. Survey completion varied between 78.7% and 84.1% for EMS and ED nurses and providers. The mean patient age was 7 years, 62.6% were non-Hispanic Black, and 60% were enrolled in public insurance programs. Of the 996 patient encounters, 33% were determined to be low acuity by the composite measure. The positive predictive value for EMS clinicians when identifying low acuity children was 0.60 (95% confidence intervals [CI], 0.58 to 0.67). The positive predictive value for ED nurses and providers was 0.67 (95% CI, 0.61 to 0.72) and 0.68 (95% CI, 0.63 to 0.74) respectively. The negative predictive value for EMS clinicians when identifying not low acuity children was 0.62 (95% CI, 0.58 to 0.67). The negative predictive value for ED nurses and providers was 0.72 (95% CI, 0.68 to 0.76) and 0.73 (95% CI, 0.70 to 0.77) respectively. Caregivers had the lowest positive predictive value 0.34 (95% CI, 0.30 to 0.40) but the highest negative predictive value 0.82 (95% CI, 0.79 to 0.85). The EMS clinicians, ED nurses and providers were more likely than caregivers to think that a child with a low acuity complaint could have been safely managed by alternative disposition.

CONCLUSION

All 4 groups studied had a limited ability to identify which children transported by EMS would have no emergency resource needs, and support for alternative disposition was limited. For children to be included in alternative disposition processes, novel triage tools, training, and oversight will be required to prevent undertriage.

Novel Use of Telemedicine by Hurricane Evacuation Shelters

Introduction: Hurricane Florence made landfall in North Carolina as a Category 1 hurricane on September 14, 2018 causing catastrophic flooding throughout much of eastern North Carolina. Large numbers of evacuees were housed in evacuation shelters established by state emergency management and county governments. The purpose of this study was to evaluate the implementation of a telemedicine service in evacuation shelters to determine whether the presence of telemedicine could alter EMS and ED utilization. Methods: We conducted a cross-sectional study that described the EMS and Emergency Department utilization of patients housed in disaster shelters during a 12 day period following Hurricane Florence. Subjects were those shelter residents in Wake or Orange counties utilizing emergency services. Data were collected from Wake County EMS, Orange County EMS, and RelyMD, the telemedicine service utilized in the shelters. Data included subject demographics, chief complaint, case disposition, telemedicine processing times, and an after-call survey to assess satisfaction and emergency department avoidance rates. De-identified data were compiled into Excel spread sheets. Results: There were a total of 194 combined telemedicine and EMS patient encounters, including 63 EMS transports, 25 refusals, 13 referrals (Wake County EMS), and 93 telemedicine patient encounters. Of the telemedicine encounters, 64 evaluations took place in Wake County shelters and 29 evaluations in the Orange County shelter. Average patient age was 49 years old; 67% were female. Forty three patients (46%) utilized the telemedicine service for obtaining medication refills, of whom 19 (44%) indicated they would have otherwise utilized an ED to refill their medication. Forty patients (43%) indicated they would have otherwise gone to an ED for care had the service not been provided, with the needs of 33 (83%) of these patients successfully managed without evaluation in an ED. Only 9 (9.7%) patients were referred by the telemedicine service to an ED for an evaluation, with 3 (3.2%) being admitted. Conclusion: Our descriptive findings suggest telemedicine can be effectively utilized in a general population evacuation shelter to reduce EMS and ED utilization and address the medical needs of the population. Further studies should be performed to assess applicability to other disaster settings.

[Tele-emergency physician : New care concept in emergency medicine]

BACKGROUND

Telemedical concepts, already successfully established in various clinical areas, such as radiology, are increasingly being implemented in the preclinical setting throughout Germany (tele-emergency physician).

OBJECTIVE

The aim of the article is to present the objectives and requirements as well as the practical implementation and the potential indications for a telemedical emergency system in the preclinical situation.

MATERIAL AND METHODS

Discussion of scientific facts and expert recommendations, specifically from experiences of the tele-emergency physician (Telenotarzt) project in an urban environment (City of Aachen). In addition, reference is made to a second pilot project in a rural region (Straubing, Bavaria).

RESULTS

The successful implementation of a prehospital telemedical emergency system requires a specific framework, in particular of a legal and technical nature. In order to achieve optimal process quality it is important to establish a comprehensive concept that takes aspects of patient safety into account. The entire dispatch process in the control center as well as the training of all involved personnel must also be taken into consideration.

CONCLUSION

With its special structures and processes, the overall concept of the telemedical emergency physician meets the changing challenges in the preclinical healthcare system and opens up new possibilities for patient care that meet the current requirements.

The Association Between Telemedicine and Emergency Department (ED) Disposition: A Stepped Wedge Design of an ED-Based Telemedicine Program in Critical Access Hospitals

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.

Efficacy and Safety of Pediatric Critical Care Physician Telemedicine Involvement in Rapid Response Team and Code Response in a Satellite Facility

OBJECTIVES

Satellite inpatient facilities of larger children's hospitals often do not have on-site intensivist support. In-house rapid response teams and code teams may be difficult to operationalize in such facilities. We developed a system using telemedicine to provide pediatric intensivist involvement in rapid response team and code teams at the satellite facility of our children's hospital. Herein, we compare this model with our in-person model at our main campus.

DESIGN

Cross-sectional.

SETTING

A tertiary pediatric center and its satellite facility.

PATIENTS

Patients admitted to the satellite facility.

INTERVENTIONS

Implementation of a rapid response team and code team model at a satellite facility using telemedicine to provide intensivist support.

MEASUREMENTS AND MAIN RESULTS

We evaluated the success of the telemedicine model through three a priori outcomes: 1) reliability: involvement of intensivist on telemedicine rapid response teams and codes, 2) efficiency: time from rapid response team and code call until intensivist response, and 3) outcomes: disposition of telemedicine rapid response team or code calls. We compared each metric from our telemedicine model with our established main campus model.

MAIN RESULTS

Critical care was involved in satellite campus rapid response team activations reliably (94.6% of the time). The process was efficient (median response time 7 min; mean 8.44 min) and effective (54.5 % patients transferred to PICU, similar to the 45-55% monthly rate at main campus). For code activations, the critical care telemedicine response rate was 100% (6/6), with a fast response time (median 1.5 min). We found no additional risk to patients, with no patients transferred from the satellite campus requiring a rapid escalation of care defined as initiation of vasoactive support, greater than 60 mL/kg in fluid resuscitation, or endotracheal intubation.

CONCLUSIONS

Telemedicine can provide reliable, timely, and effective critical care involvement in rapid response team and Code Teams at satellite facilities.

A systematic review of prehospital telehealth utilization

Objective There has been moderate evidence of telehealth utilization in the field of emergency medicine, but less is known about telehealth in prehospital emergency medical services (EMS). The objective of this study is to explore the extent, focus, and utilization of telehealth for prehospital emergency care through the analysis of published research. Methods The authors conducted a systematic literature review by extracting data from multiple research databases (including MEDLINE/PubMed, CINAHL Complete, and Google Scholar) published since 2000. We used consistent key search terms to identify clinical interventions and feasibility studies involving telehealth and EMS, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Results We identified 68 articles focused specifically on telehealth interventions in prehospital care. The majority (54%) of the studies involved stroke and acute cardiovascular care, while only 7% of these (4) focused on telehealth for primary care. The two most common delivery methods were real-time video-conferencing capabilities (38%) and store and forward (25%); and this variation was based upon the clinical focus. There has been a significant and positive trend towards greater telehealth utilization. European telehealth programs were most common (51% of the studies), while 38% were from the United States. Discussion and Conclusions Despite positive trends, telehealth utilization in prehospital emergency care is fairly limited given the sheer number of EMS agencies worldwide. The results of this study suggest there are significant opportunities for wider diffusion in prehospital care. Future work should examine barriers and incentives for telehealth adoption in EMS.

Telehealth-Enabled Emergency Medical Services Program Reduces Ambulance Transport to Urban Emergency Departments

INTRODUCTION

Emergency medical services (EMS) agencies transport a significant majority of patients with low acuity and non-emergent conditions to local emergency departments (ED), affecting the entire emergency care system's capacity and performance. Opportunities exist for alternative models that integrate technology, telehealth, and more appropriately aligned patient navigation. While a limited number of programs have evolved recently, no empirical evidence exists for their efficacy. This research describes the development and comparative effectiveness of one large urban program.

METHODS

The Houston Fire Department initiated the Emergency Telehealth and Navigation (ETHAN) program in 2014. ETHAN combines telehealth, social services, and alternative transportation to navigate primary care-related patients away from the ED where possible. Using a case-control study design, we describe the program and compare differences in effectiveness measures relative to the control group.

RESULTS

During the first 12 months, 5,570 patients participated in the telehealth-enabled program, which were compared against the same size control group. We found a 56% absolute reduction in ambulance transports to the ED with the intervention compared to the control group (18% vs. 74%, P<.001). EMS productivity (median time from EMS notification to unit back in service) was 44 minutes faster for the ETHAN group (39 vs. 83 minutes, median). There were no statistically significant differences in mortality or patient satisfaction.

CONCLUSION

We found that mobile technology-driven delivery models are effective at reducing unnecessary ED ambulance transports and increasing EMS unit productivity. This provides support for broader EMS mobile integrated health programs in other regions.

Telemedicine in the intensive care unit: its role in emergencies and disaster management

Disasters and emergencies lead to an overburdened health care system after the event, so additional telemedicine support can improve patient outcomes. If telemedicine is going to become an integral part of disaster response, there needs to be improved preparation for the use of telemedicine technologies. Telemedicine can improve patient triage, monitoring, access to specialists, health care provider burnout, and disaster recovery. However, the evidence for telemedicine and tele-intensive care in the disaster setting is limited, and it should be further studied to identify situations in which it is the most clinically effective and cost-effective.

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.

Alternatives to Traditional EMS Dispatch and Transport: A Scoping Review of Reported Outcomes

Objectives

Emergency medical services (EMS) programs, which provide an alternative to traditional EMS dispatch or transport to the emergency department (ED), are becoming widely implemented. This scoping review identified and catalogued all outcomes used to measure such alternative EMS programs.

Data Source

Broad systematized bibliographic and grey literature searches were conducted.

Study Selection

Inclusion criteria were 911 callers/EMS patients, reported on alternatives to traditional EMS dispatch OR traditional EMS transport to the ED, and reported an outcome measure.

Data Extraction

The reports were categorized as either alternative to dispatch or to EMS transport, and outcome measures were categorized and described.

Data Synthesis

The bibliographic search retrieved 13,215 records, of which 34 articles met the inclusion criteria, with an additional 10 added from reference list hand-searching (n=44 included). In the grey literature search, 31 websites were identified, from which four met criteria and were retrieved (n=4 included). Fifteen reports (16 studies) described alternatives to EMS dispatch, and 33 reports described alternatives to EMS transport. The most common outcomes reported in the alternatives to EMS dispatch reports were service utilization and decision accuracy. Twenty-four different specific outcomes were reported. The most common outcomes reported in the alternatives to EMS transport reports were service utilization and safety, and 50 different specific outcomes were reported.

Conclusions

Numerous outcome measures were identified in reports of alternative EMS programs, which were catalogued and described. Researchers and program leaders should achieve consensus on uniform outcome measures, to allow benchmarking and improve comparison across programs.

Appropriateness of disposition following telemedicine consultations in rural emergency departments

OBJECTIVES

To compare the appropriateness of hospital admission in eight rural emergency departments among a cohort of acutely ill and injured children who receive telemedicine consultations from pediatric critical care physicians to a cohort of similar children who receive telephone consultations from the same group of physicians.

DESIGN

Retrospective cohort study between January 2003 and May 2012.

SETTING

Eight rural emergency departments in Northern California.

PATIENTS

Acutely ill and injured children triaged to the highest-level triage category who received either telemedicine or telephone consultations.

INTERVENTIONS

Telemedicine and telephone consultations.

MEASUREMENTS AND MAIN RESULTS

We compared the overall and stratified observed-to-expected hospital admission ratios between telemedicine and telephone cohorts by calculating the risk of admission using the second generation of Pediatric Risk of Admission score and the Revised Pediatric Emergency Assessment Tool. A total of 138 charts were reviewed; 74 children received telemedicine consultations and 64 received telephone consultations. The telemedicine cohort had fewer hospital admissions compared with the telephone cohort (59.5% vs 87.5%; p < 0.05). Although the telemedicine cohort had lower observed-to-expected admission ratios than the telephone cohort, these differences were not statistically different (Pediatric Risk of Admission II, 2.36 vs 2.58; Revised Pediatric Emergency Assessment Tool, 2.34 vs 2.57). This result did not change when the cohorts were stratified into low (below median) and high (above median) risk of admission cohorts, using either Pediatric Risk of Admission II (low risk, 18.25 vs 22.81; high risk, 1.40 vs 1.54) or Revised Pediatric Emergency Assessment Tool (low risk, 5.35 vs 5.94; high risk, 1.51 vs 1.81).

CONCLUSIONS

Although the overall admission rate among patients receiving telemedicine consultations was lower than that among patients receiving telephone consultations, there were no statistically significant differences between the observed-to-expected admission ratios using Pediatric Risk of Admission II and Revised Pediatric Emergency Assessment Tool. Our findings may be reassuring in the context of previous research, suggesting that telemedicine specialty consultations can aid in the delivery of more appropriate, safer, and higher quality of care.

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.

The role of the pediatrician in rural emergency medical services for children

In rural America, pediatricians can play a key role in the development, implementation, and ongoing supervision of emergency medical services for children (EMSC). Pediatricians may represent the only source of pediatric expertise for a large region and are a vital resource for rural physicians (eg, general and family practice, emergency medicine) and other rural health care professionals (physician assistants, nurse practitioners, and emergency medical technicians), providing education about management and prevention of pediatric illness and injury; appropriate equipment for the acutely ill or injured child; and acute, chronic, and rehabilitative care. In addition to providing clinical expertise, the pediatrician may be involved in quality assurance, clinical protocol development, and advocacy, and may serve as a liaison between emergency medical services and other entities working with children (eg, school nurses, child care centers, athletic programs, and programs for children with special health care needs).

The Role of Telemedicine in Treating the Critically Ill

Telemedicine use has been increasing exponentially and is expected to become a common tool in remote emergency departments, inpatient wards, and ICUs for acute care. Telemedicine involves real-time, live interactive high-definition video and audio communication that allows critical care physicians to have a virtual presence at the bedside of any critically ill patient. There is increasing data to support new care models that incorporate telemedicine in caring for the critically ill, resulting in higher care quality; more efficient resource use with improved cost-effectiveness; and higher patient, family, and remote provider satisfaction. As further research is conducted, the best use of telemedicine will be better defined and will result in increased access to critical care expertise to a larger population of patients requiring ICU services.

Use of telehealth for patients referred to a retrieval service: timing, destination, mode of transport, escort level and patient care

We examined the utility of telehealth in assisting the decision-making processes of aeromedical coordinators, with particular focus on the timing, destination, mode of transport and escort level. Medical coordinators from the Northern Operations site of the Queensland emergency retrieval service were asked to complete a survey form about the changes that telehealth made to their retrieval decision-making process. Information was collected in six areas: diagnosis, severity, priority, crew, mode of transport and destination. During a 12-month period, there were 403 emergency referrals from the five participating sites. There were 136 eligible patient referrals for analysis, of which 90 did not have teleconsultations performed; the most common reasons were that the medical coordinator was too busy with other work or the new procedure was forgotten ( n = 39, 43%). The remaining 46 patients had a teleconsultation during the trial and 44 data sheets were available for analysis. In 21 cases some component of the decision-making process was altered by the use of telehealth, with decisions being significantly altered in nine cases. Most alterations were for severity of patient condition, then diagnosis and priority of transfer. The use of telehealth was thought to be beneficial in confirming the original decision in 30 cases. Telehealth was not of assistance in seven cases. Telehealth appears to assist in accurate decision-making during the medical coordination of aeromedical retrievals.

EMS provider determinations of necessity for transport and reimbursement for EMS response, medical care, and transport: combined resource document for the National Association of EMS Physicians position statements

With increasing demands for emergency medical services (EMS), many EMS jurisdictions are utilizing EMS provider-initiated nontransport policies as a method to offload potentially nonemergent patients from the EMS system. EMS provider determination of medical necessity, resulting in nontransport of patients, has the potential to avert unnecessary emergency department visits. However, EMS systems that utilize these policies must have additional education for the providers, a quality improvement process, and active physician oversight. In addition, EMS provider determination of nontransport for a specific situation should be supported by evidence in the peer-reviewed literature that the practice is safe. Further, EMS systems that do not utilize these programs should not be financially penalized. Payment for EMS services should be based on the prudent layperson standard. EMS systems that do utilize nontransport policies should be appropriately reimbursed, as this represents potential cost savings to the health care system.

Paramedic determinations of medical necessity: a meta-analysis

INTRODUCTION

Reducing unnecessary ambulance transports may have operational and economic benefits for emergency medical services (EMS) agencies and receiving emergency departments. However, no consensus exists on the ability of paramedics to accurately and safely identify patients who do not require ambulance transport. Objective. This systematic review and meta-analysis evaluated studies reporting U.S. paramedics' ability to determine medical necessity of ambulance transport.

METHODS

PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Cochrane Library databases were searched using Cochrane Prehospital and Emergency Care Field search terms combined with the Medical Subject Headings (MeSH) terms "triage"; "utilization review"; "health services misuse"; "severity of illness index," and "trauma severity indices." Two reviewers independently evaluated each title to identify relevant studies; each abstract then underwent independent review to identify studies requiring full appraisal. Inclusion criteria were original research; emergency responses; determinations of medical necessity by U.S. paramedics; and a reference standard comparison. The primary outcome measure of interest was the negative predictive value (NPV) of paramedic determinations. For studies reporting sufficient data, agreement between paramedic and reference standard determinations was measured using kappa; sensitivity, specificity, and positive predictive value (PPV) were also calculated.

RESULTS

From 9,752 identified titles, 214 abstracts were evaluated, with 61 studies selected for full review. Five studies met the inclusion criteria (interrater reliability, kappa = 0.75). Reference standards included physician opinion (n = 3), hospital admission (n = 1), and a composite of physician opinion and patient clinical circumstances (n = 1). The NPV ranged from 0.610 to 0.997. Results lacked homogeneity across studies; meta-analysis using a random-effects model produced an aggregate NPV of 0.912 (95% confidence interval: 0.707-0.978). Only two studies reported complete 2 x 2 data: kappa was 0.105 and 0.427; sensitivity was 0.992 and 0.841; specificity was 0.356 and 0.581; and PPV was 0.158 and 0.823.

CONCLUSION

The results of the few studies evaluating U.S. paramedic determinations of medical necessity for ambulance transport vary considerably, and only two studies report complete data. The aggregate NPV of the paramedic determinations is 0.91, with a lower confidence limit of 0.71. These data do not support the practice of paramedics' determining whether patients require ambulance transport. These findings have implications for EMS systems, emergency departments, and third-party payers.

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.

The effectiveness of video-telemedicine for screening of patients requesting emergency air medical transport (EAMT)

BACKGROUND

Demand for emergency air medical transport (EAMT) services have increased in recent years. However, the high costs of these services have raised questions on the benefit to patient outcomes. In this study, we evaluate the effectiveness of video-telemedicine for the preflight screening of patients for air medical transports.

METHOD

A prospective cohort study. Medical records of patients transported from the Penghu Islands to Taiwan were retrospectively collected from November 1999 to October 2002 (stage 1). In addition, we collected medical records of patients who were preflight-screened by physicians using video Web cameras from November 1, 2002 through August 30, 2003 (stage 2). The intervention in stage 2 included a set of protocols and screening criteria for EAMT implemented by the National Aeromedical Consultation Center (NACC). In stage 1, there were no standardized protocols or screening guidelines for EAMT. The EAMT system before implementing preflight screening and telemedicine was mostly based on patient's requests and their health condition determined by the treating medical officers (TMO).

RESULTS

A total of 822 transfers were included in this study. Patient demographic backgrounds in the two groups were similar on gender, age, disease classification, and types of illnesses. Patients in stage 2 were significantly older than those in stage 1. In a comparison of flight frequencies between the two stages, the results revealed a 36.2% reduction of EAMT applications in stage 2. The flight approval rate was 91.2%. The intervention in stage 2 also presented a significant reduction in cross-zone transport (16.1% to 0.1% to the northern Taiwan region). Within-zone transfers increased from 74.9% to 88.3%. Cost analysis showed that physician triage in stage 2 resulted in a total annual savings on EAMTs of US 448,986 dollars.

CONCLUSIONS

This study demonstrates the physician-assisted preflight screening using video-telemedicine significantly reduced the frequency of unnecessary air medical transports and consequently led to reduced costs. Video-telemedicine can be an essential tool to support physicians in decision-making for patient screening.

Regional Air Transport of Burn Patients: A Case for Telemedicine?

BACKGROUND

Air transport of burn patients is plagued by frequent "overtriage." We examined the use of air transport and the feasibility of using alternative methods such as telemedicine to assist in evaluation and treatment of burn patients within our region.

METHODS

We reviewed all burn patients transported by air during 2000 to 2001. Each patient was classified as being most appropriate for air, ground, or family transport. In addition, a decision was made regarding whether telemedicine evaluation of the patient before transport could have significantly altered initial treatment decisions.

RESULTS

Two hundred twenty-five acutely burned patients were transferred from referring hospitals in nine states, at a mean distance of 246 air miles. Mean burn size calculated by burn center physicians was 19.7% total body surface area, whereas referring physicians' mean estimate was 29% total body surface area. In 92 cases, over- or underestimation of burn size by referring physicians of as much as 560% or decisions regarding performance of endotracheal intubation suggested that telemedicine evaluation before transport might have significantly altered transport decisions or care. Air transport charges exceeded hospital charges in 21 cases.

CONCLUSION

Frequent discrepancies in burn assessment contribute to overuse of air transport. The ability to evaluate burn patients by telemedicine may have the potential to assist decisions regarding transfer, avoid errors in initial care, and reduce costs. We are currently attempting to develop and test such a system.

The success of emergency telemedicine at the State University of New York at Buffalo

The Telemedicine Program at the State University of New York at Buffalo, School of Medicine, and the Erie County Medical Center (UB/ECMC) represents a "quiet success story" for telemedicine development. Though a relatively young program starting in 1992, it demonstrates steady and consistent progress in the areas of clinical services, education and research as it continues to develop as a comprehensive university telemedicine program. The Emergency Telemedicine program provided 2,294 consultations in 2001. Other services included clinics in Gastroenterology, Infectious Disease (HIV/AIDS), Psychiatry, Orthopedic Hand Surgery, Dermatology, and Neurology. The UB/ECMC program has sponsored regular education activities with a focus on internet protocol (IP) videoconferencing for grand rounds in emergency medicine and traffic injury research, nursing education, distance precepting of nurse practitioner students on clinical rotations, Megaconference I and II presentations, and the continuing exploration of advanced tools for educational presentation over the internet. The program's research activities have focused on portable, roll-about telemedicine systems and virtual palpation using a data glove.
