Austere, remote, and disaster medicine missions: an operational mnemonic can help organize a deployment.

Medical care in resource-limited environments (austere settings) can occur in the context of a disaster, wilderness, or a tactical field operation. Regardless of the type of environment, there are common organizational themes in most successful humanitarian missions that occur in harsh natural or manmade environmental conditions. These principles prioritize the initiation and execution of any given deployment in austere or remote settings, diverging from priorities that would occur in a situation in which change to the existing medical structure is intact and operating well. Attention to these priorities not only helps providers to deliver medical care to people in need during a period of resource limitations but it also can keep providers, teams, the public, and patients safe during and after a deployment.

Portable handheld ultrasound in austere environments: use in the Haiti disaster.

INTRODUCTION: A 7.0 magnitude earthquake struck Haiti on January 12, 2010, resulting in 222,000 deaths and 300,000 injuries. Three weeks after the initial quake, the New Mexico Disaster Medical Assistance Team (NM DMAT-1) was deployed to Haiti for ongoing medical relief. During this deployment, a portable handheld ultrasound machine was tested for usefulness in aiding with patient care decisions. OBJECTIVE: The utility of portable ultrasound to help with triage and patient management decisions in a major disaster setting was evaluated. METHODS: Retrospective observational non-blinded images were obtained on 51 patients voluntarily presenting to the Gheskio Field clinic at Port-au-Prince. Ultrasound was used for evaluation of undifferentiated hypotension, torso trauma, pregnancy, non-traumatic abdominal pain, deep venous thrombosis and pulmonary embolism, and dyspnea-chest pain, as well as for assisting with procedures. Scans were obtained using a Signos personal handheld ultrasound machine with images stored on a microSD card. Qualitative data were reviewed to identify whether ultrasound influenced management decisions, and results were categorized in terms of percent of scans that influenced management. RESULTS: Fifty-one ultrasound scans on 50 patients were performed, with 35% interpreted as positive, 41% as negative, and 24% as equivocal. The highest yields of information were for abdominal ultrasound and ultrasound related to pregnancy. Ultrasound influenced decisions on patient care in 70% of scans. Most of these decisions were reflected in the clinician's confidence in discharging a patient with or without non-emergent follow-up. CONCLUSION: The use of a handheld portable ultrasound machine was effective for patient management decisions in resource-poor settings, and decreased the need to triage selected patients to higher levels of care. Ultrasound was very useful for evaluation of non-traumatic abdominal pain. Dynamic capability is necessary for ultrasound evaluation of undifferentiated hypotension and cardiac and lung examinations. Ultrasound also was useful for guidance during procedural applications, and for aiding in the diagnosis of parasitic diseases.

AvaLife-A New Multi-Disciplinary Approach Supported by Accident and Field Test Data to Optimize Survival Chances in Rescue and First Aid of Avalanche Patients.

Snow sports in the backcountry have seen a steep increase in popularity, and therefore preparedness for efficient companion and organized rescue is important. While technical rescue skills are widely taught, there is a lack of knowledge regarding first aid for avalanche patients. The stressful and time-critical situation for first responders requires a rule-based decision support tool. AvaLife has been designed from scratch, applying mathematical and statistical approaches including Monte Carlo simulations. New analysis of retrospective data and large prospective field test datasets were used to develop evidence-based algorithms exclusively for the avalanche rescue environment. AvaLife differs from other algorithms as it is not just a general-purpose CPR algorithm which has been slightly adapted for the avalanche patient. The sequence of actions, inclusion of the ≥150 cm burial depth triage criterion, advice to limit CPR duration for normothermic patients to 6 min in case of multiple burials and shortage of resources, criteria for using recovered subjects as a resource in the ongoing rescue, the adapted definition of "injuries incompatible with life", reasoning behind the utmost importance of rescue breaths, as well as the updated BLS-iCPR algorithm make AvaLife useful in single and multiple burial rescue. AvaLife is available as a companion rescue basic life support (BLS) version for the recreational user and an advanced companion and organized rescue BLS version for guides, ski patrols and mountain rescuers. AvaLife allows seamless interoperability with advanced life support (ALS) qualified medical personnel arriving on site.

Comparison of emergency physicians' and juris doctors' opinions on emergency department patient restraints usage.

OBJECTIVES: Emergency physicians (EPs) and Juris Doctors (JDs) often disagree on the correct use of restraints for emergency department (ED) patients. The objective of the study was to compare EPs and JDs propensity to restrain patients given various scenarios. The study hypothesis was that EPs and JDs would agree on when to restrain emergency patients. METHODS: This was a prospective cross-sectional study. Twenty-two EPs and 27 JDs were asked to complete the Video Assessment of Propensity to use Emergency Restraints Scale (VAPERS). The VAPERS scale consists of 17 scenarios utilizing actors who were videotaped to produce a scale. Results obtained include overall likelihood to restrain and likelihood to restrain specific subgroups of patients such as those who are a danger to themselves, a danger to others, medically unstable, trauma patients, altered patients, belligerent patients, agitated patients, calm patients, and patients with normal mental status. A two-way mixed model average intraclass correlation coefficient (ICC) was used to determine scale reliability. Unpaired t-tests with confidence intervals (CI) were used to compare the two professions on VAPERS results and on individual scenarios. RESULTS: Overall, EPs were more likely to restrain patients than JDs (46% vs 37%), although this did not reach statistical significance. The statistically significant EP-JD disagreement, with EPs more likely to restrain patients, occurred if the patients were calm. Common themes in the differences emerged from evaluation of the two groups' comments. CONCLUSIONS: EPs and JDs disagree on restraint use. These EP-JD differences were statistically significant in patients who were calm.

Regional highlights in global emergency medicine development.

There are a number of notable trends in the development of EM that have been highlighted at the regional level globally. From the establishment of formal EM training as the standard of care to practice in an ED to the influence of transnational regulatory bodies and financing mechanisms on specialty development and the broad-based issues of health security that affect EM, the specialty continues to grow around the world. As practitioners in each of these regions struggle to respond effectively to the development issues and challenges presented here, they continue to advance EM as one of the more dynamic young specialties in medicine. The regions presented here are as distinctive as the people who practice our specialty; however, in many respects the highlights and challenges are universal. This recognition is perhaps what motivates the appeal for collaboration in international EM development.

Core content for wilderness medicine fellowship training of emergency medicine graduates.

Wilderness medicine is the practice of resource-limited medicine under austere conditions. In 2003, the first wilderness medicine fellowship was established, and as of March 2013, a total of 12 wilderness medicine fellowships exist. In 2009 the American College of Emergency Physicians Wilderness Medicine Section created a Fellowship Subcommittee and Taskforce to bring together fellowship directors, associate directors, and other interested stakeholders to research and develop a standardized curriculum and core content for emergency medicine (EM)-based wilderness medicine fellowships. This paper describes the process and results of what became a 4-year project to articulate a standardized curriculum for wilderness medicine fellowships. The final product specifies the minimum core content that should be covered during a 1-year wilderness medicine fellowship. It also describes the structure, length, site, and program requirements for a wilderness medicine fellowship.

Development of the Video Assessment of Propensity to Use Emergency Restraints Scale (VAPERS): results of the VAPERS Study Group.

BACKGROUND: Emergency physicians (EPs) may disagree on when or whether patients need restraints. There is no good objective measure of the likelihood of EPs to restrain patients. OBJECTIVES: To 1) develop a scale to determine the likelihood that an EP would restrain a patient, 2) develop subscale scoring, and 3) determine a shortened version that correlates highly with the full scale. METHODS: This was a prospective cross sectional study. The Video Assessment of Propensity to use Emergency Restraints Scale (VAPERS), consisting of 17 scenarios utilizing actors, was videotaped to produce a research video assessment tool. The VAPERS was designed by development experts to reflect the spectrum of patients who are considered for restraint in an emergency department. The VAPERS was piloted among a 22-member pilot panel of EPs (faculty and residents). The pilot panel was asked to determine the degree to which each video patient possessed the following patient characteristics: medical instability, trauma, belligerence, agitation, and altered mental status. Each "degree of characteristic" was measured on a separate 100-mm visual analog scale. Participants were then asked whether or not they would restrain each patient and whether the patient exhibited the potential to harm him- or herself or others. VAPERS subscales were developed for the likelihood to restrain patients with each of the patient characteristics. Spearman correlations were used for all comparisons. Linear regression was used to determine which patient characteristics were most related to likelihood to restrain and to develop a reduced scale to predict the overall likelihood to restrain. RESULTS: The overall VAPERS score ranged from 0 to 100, with a median of 50 (interquartile range [IQR], 24-88). The visual analog scale results of how likely each video patient possessed specific characteristics were as follows: medical instability ranged from 0 to 100 (median, 32; IQR, 12-64), trauma ranged from 0 to 69 (median, 0; IQR, 0-31), belligerence ranged from 20 to 93 (median, 28; IQR, 14-63), agitation ranged from 3 to 84 (median, 52; IQR, 23-72), and altered mental status ranged from 1 to 93 (median, 29; IQR, 16-69). Linear regression indicated that two characteristic variables (danger to self and degree of agitation) in the video scenarios were highly correlated (0.87) with overall likelihood to restrain. Based on the results, the authors developed a shortened video assessment tool consisting of five of the original videos that were highly correlated (R = 0.94) with the full VAPERS scale on overall likelihood to restrain. CONCLUSIONS: The VAPERS scale covers a wide range of important variables in emergency situations. It successfully measured likelihood to restrain in this pilot study for overall situations, and for subgroups, based on patient characteristics. A shortened five-video VAPERS also successfully measured the overall likelihood to restrain.

The management of open fractures.

This is a review of Medline and PubMed articles on open fractures published in the English literature between 1945 and April 2005. The emphasis of most published articles has been placed on definitive treatment of these injuries at sophisticated referral hospitals. The prehospital emphasis has been on rapid evacuation and referral to ensure that definitive treatment can be initiated as quickly as possible. Little has been discussed about the management of these injuries in remote settings where evacuation may consume considerably more time. Contemporary recommendations for management of these injuries are reviewed.

Development of a wilderness and travel medicine rotation in an academic setting.

Wilderness medicine courses tend to teach similar topics, but they can differ with respect to philosophy, teaching methods, and financing. Our not-for-profit course is academically based and is similar to other programs with regard to presentations of didactic material and outdoor training, but there are also important differences in teaching methodology that are not used by other programs to date. Innovative methods, such as problem-based learning and use of the human patient simulator, which are unique to our program, have been successful in our courses and may be of use to wilderness medical education. We hope that sharing information about our program will help make wilderness medicine training more standardized and uniform.
