Wilderness Medical Society Clinical Practice Guidelines for Spinal Cord Protection: 2024 Update.

The Wilderness Medical Society reconvened an expert panel to update best practice guidelines for spinal cord protection during trauma management. This panel, with membership updated in 2023, was charged with the development of evidence-based guidelines for management of the injured or potentially injured spine in wilderness environments. Recommendations are made regarding several parameters related to spinal cord protection. These recommendations are graded based on the quality of supporting evidence and balance the benefits and risks/burdens for each parameter according to American College of Chest Physicians methodology. Key recommendations include the concept that interventions should be goal-oriented (spinal cord/column protection in the context of overall patient and provider safety) rather than technique-oriented (immobilization). An evidence-based, goal-oriented approach excludes the immobilization of suspected spinal injuries via rigid collars or backboards.

Wilderness Medical Society Clinical Practice Guidelines for Medical Direction of Search and Rescue Teams.

The Wilderness Medical Society convened a panel to review available evidence supporting practices for medical direction of search and rescue teams. This panel included of members of the Wilderness Medical Society Search and Rescue Committee, the National Association of EMS Physicians Wilderness Committee, and leadership of the Mountain Rescue Association. Literature about definitions and terminology, epidemiology, currently accepted best practices, and regulatory and legal considerations was reviewed. The panel graded available evidence supporting practices according to the American College of Chest Physicians criteria and then made recommendations based on that evidence. Recommendations were based on the panel's collective clinical experience and judgment when published evidence was lacking.

Wilderness Medical Society Clinical Practice Guidelines for the Treatment and Prevention of Drowning: 2024 Update.

The Wilderness Medical Society convened a panel to review available evidence supporting practices for acute management of drowning in out-of-hospital and emergency care settings. Literature about definitions and terminology, epidemiology, rescue, resuscitation, acute clinical management, disposition, and drowning prevention was reviewed. The panel graded available evidence supporting practices according to the American College of Chest Physicians criteria and then made recommendations based on that evidence. Recommendations were based on the panel's collective clinical experience and judgment when published evidence was lacking. This is the second update to the original practice guidelines published in 2016 and updated in 2019.

Wilderness Paramedic-A Practice Analysis.

Emergency medical services (EMS) has existed in its modern form for over 50 years. EMS has become a critical public safety net and access point to the larger health care system. Mature EMS systems are in place in most urban areas. However, EMS systems are not as developed in wilderness areas. A barrier to further development of these systems is the lack of an agreed-upon standard of minimum competence and validation of specialized practice. A practice analysis was completed to create such standards. The practice analysis was completed using a multi-step process. A group of subject matter experts constructed a survey of tasks and knowledge needed for wilderness EMS (WEMS) specialty practice. The tasks and knowledge were validated through an industry survey. A total of 947 surveys were submitted for analysis. Of these, 196 were at least 55% complete and used for analysis. North America was heavily represented as a primary practice location with 177 (90.3%) responses out of the 196 total. Of these 177 responses, 164 (92.7%) were from the United States and 12 (6.8%) were from Canada. One hundred seven of the 116 tasks identified by the subject matter expert group were passed by the survey group, and 164 of the 175 knowledge statements were passed by the survey group. An index of agreement (IOA) was calculated and found to be greater than 0.9 for each task and knowledge statement across all subgroups. A content coverage rating was also calculated and the results indicate survey participants felt the content was "adequate" to "well" covered. The survey results were used to construct a pilot examination. Beta testing of the pilot examination was performed. The beta test results were analyzed and a cut score was determined using the Angoff method with a Beuk compromise. The final product of this process is a defensible exam that will certify candidates' cognitive knowledge of the specialty of WEMS. Completion of this practice analysis solidifies WEMS as distinct subspecialty of out-of-hospital medicine. Additionally, it establishes a consensus definition of wilderness paramedicine and standards that may be used by WEMS systems and regulatory entities.

Use of Ultrasound for Joint Dislocation Reduction in an Austere Wilderness Setting: A Case Report.

Point-of-care ultrasound has been shown to have a demonstrable impact in the austere/out-of-hospital environment. As ultrasounds become more affordable and portable, a myriad of uses in austere environments are becoming recognized. We present a case of a stranded hiker with an ultrasound-confirmed glenohumeral joint dislocation who underwent ultrasound-guided intra-articular lidocaine injection and ultrasound-confirmed reduction. This procedure allowed the patient to hike out under his own power, avoiding the potential dangers of extrication to both patient and rescuers. We believe this case demonstrates the feasibility and utility of ultrasound in the out-of-hospital environment both procedurally and diagnostically.

This panel, with membership updated in 2018, was charged with the development of evidence-based guidelines for management of the injured or potentially injured spine in wilderness environments. Recommendations are made regarding several parameters related to spinal cord protection. These recommendations are graded based on the quality of supporting evidence and balance the benefits and risks/burdens for each parameter according to the methodology stipulated by the American College of Chest Physicians.

Medical Oversight, Educational Core Content, and Proposed Scopes of Practice of Wilderness EMS Providers: A Joint Project Developed by Wilderness EMS Educators, Medical Directors, and Regulators Using a Delphi Approach.

INTRODUCTION: A disparity exists between the skills needed to manage patients in wilderness EMS environments and the scopes of practice that are traditionally approved by state EMS regulators. In response, the National Association of EMS Physicians Wilderness EMS Committee led a project to define the educational core content supporting scopes of practice of wilderness EMS providers and the conditions when wilderness EMS providers should be required to have medical oversight. METHODS: Using a Delphi process, a group of experts in wilderness EMS, representing educators, medical directors, and regulators, developed model educational core content. This core content is a foundation for wilderness EMS provider scopes of practice and builds on both the National EMS Education Standards and the National EMS Scope of Practice Model. These experts also identified the conditions when oversight is needed for wilderness EMS providers. RESULTS: By consensus, this group of experts identified the educational core content for four unique levels of wilderness EMS providers: Wilderness Emergency Medical Responder (WEMR), Wilderness Emergency Medical Technician (WEMT), Wilderness Advanced Emergency Medical Technician (WAEMT), and Wilderness Paramedic (WParamedic). These levels include specialized skills and techniques pertinent to the operational environment. The skills and techniques increase in complexity with more advanced certification levels, and address the unique circumstances of providing care to patients in the wilderness environment. Furthermore, this group identified that providers having a defined duty to act should be functioning with medical oversight. CONCLUSION: This group of experts defined the educational core content supporting the specific scopes of practice that each certification level of wilderness EMS provider should have when providing patient care in the wilderness setting. Wilderness EMS providers are, indeed, providing health care and should thus function within defined scopes of practice and with physician medical director oversight.

Extreme event medicine: considerations for the organisation of out-of-hospital care during obstacle, adventure and endurance competitions.

Obstacle, adventure and endurance competitions in challenging or remote settings are increasing in popularity. A literature search indicates a dearth of evidence-based research on the organisation of medical care for wilderness competitions. The organisation of medical care for each event is best tailored to specific race components, participant characteristics, geography, risk assessments, legal requirements, and the availability of both local and outside resources. Considering the health risks and logistical complexities inherent in these events, there is a compelling need for guiding principles that bridge the fields of wilderness medicine and sports medicine in providing a framework for the organisation of medical care delivery during wilderness and remote obstacle, adventure and endurance competitions. This narrative review, authored by experts in wilderness and operational medicine, provides such a framework. The primary goal is to assist organisers and medical providers in planning for sporting events in which participants are in situations or locations that exceed the capacity of local emergency medical services resources.

Participation of iatrogenically coagulopathic patients in wilderness activities.

An increasing number of patients routinely undergo long-term anticoagulation with warfarin or other pharmacological agents. There is little evidence and no consensus documents in the literature regarding the appropriateness and relative risk of their participation in wilderness activities. We present a case report, conduct an analysis of the limited literature that is available, and make recommendations for wilderness medicine practitioners and screening personnel.

Retrieval of additional epinephrine from auto-injectors.

Anaphylaxis is a challenging condition for any austere environment. It is unpredictable, has sudden onset and a high fatality rate, and is responsive only to epinephrine, a prescription medication. The Wilderness Medical Society has formally recommended that non-medical providers working in austere environments be trained to administer epinephrine. Medical providers frequently prescribe auto-injectors for this purpose due to their ease of use by nonmedical providers. However, auto-injectors have limitations in the wilderness environment, particularly due to their single-dose (or at most 2-dose) design. This paper describes an austere environment technique for obtaining multiple additional doses of epinephrine from auto-injectors that have already been used as designed.

Medical direction of wilderness and other operational emergency medical services programs.

Within a healthcare system, operational emergency medical services (EMS) programs provide prehospital emergency care to patients in austere and resource-limited settings. Some of these programs are additionally considered to be wilderness EMS programs, a specialized type of operational EMS program, as they primarily function in a wilderness setting (eg, wilderness search and rescue, ski patrols, water rescue, beach patrols, and cave rescue). Other operational EMS programs include urban search and rescue, air medical support, and tactical law enforcement response. The medical director will help to ensure that the care provided follows protocols that are in accordance with local and state prehospital standards, while accounting for the unique demands and needs of the environment. The operational EMS medical director should be as qualified as possible for the specific team that is being supervised. The medical director should train and operate with the team frequently to be effective. Adequate provision for compensation, liability, and equipment needs to be addressed for an optimal relationship between the medical director and the team.

Evolution of the literature identifying physicians' roles in leadership, clinical development, and practice of the subspecialty of emergency medical services.

PURPOSE: The 2007 Institute of Medicine report entitled Emergency Medical Services at the Crossroads identified a need for the establishment of physician subspecialty certification in emergency medical services (EMS). The purpose of this study was to identify and explore the evolution of publications that define the role of the physician in EMS systems in the United States. METHODS: Three comprehensive searches were undertaken to identify articles that define the physician's role in the leadership, clinical development, and practice of EMS. Independent reviewers then evaluated these articles to further determine whether the articles identified the physician's role in EMS. Then, identified articles were classified by the type of publication in order to evaluate the transition from a non-peer reviewed to peer-reviewed literature base and an analysis was performed on the differences in the growth between these two groups. In addition, for the peer-reviewed articles, an analysis was performed to identify the proportion of articles that were quantitative versus qualitative in nature. RESULTS: The comprehensive review identified 1,504 articles. Ninety articles were excluded due to lack of relevance to the US. The remaining 1,414 articles were reviewed, and 194 papers that address the physician's role within EMS systems were identified; 72 additional articles were identified by hand search of references for a total of 266 articles. The percentage of peer-reviewed articles has increased steadily over the past three decades. In addition, the percentage of quantitative articles increased from the first decade to the second and third decades. CONCLUSIONS: This comprehensive review demonstrates that over the past 30 years an evidence base addressing the role of the physician in EMS has developed. This evidence base has steadily evolved to include a greater proportion of peer-reviewed, quantitative literature.

Advanced wilderness life support education using high-technology patient simulation.

OBJECTIVE: (1) To determine if, after using the simulation mannequin SimMan in a wilderness "megacode" exercise, participants believe high-tech simulators are an effective tool for learning wilderness medicine skills. (2) To determine if participants believe high-tech simulation mannequins should be used with more or less frequency in future wilderness medicine exercises. METHODS: After completing a basic training session outlining the capabilities of SimMan and completing a wilderness megacode (defined as a series of progressive conditions that accumulate over time) using SimMan, participants were surveyed to ascertain whether they perceived SimMan to be an effective teaching tool for wilderness medical skills and to determine if they would like SimMan to be used with greater frequency at future wilderness medicine courses. The data were compiled and analyzed using Microsoft Excel. RESULTS: Participants found the wilderness SimMan experience to be an effective tool with an average score of 3.15 on a scale where 4 is most effective and 1 is least effective. Participants also desired to see high-tech simulation more frequently in wilderness courses with a score of 3, on a scale where 4 is more frequently and 1 is less frequently. There was little difference in responses based on previous experience with simulation. CONCLUSIONS: High-tech simulation is an underused tool for wilderness medicine education. Currently, several barriers exist to its implementation in wilderness medicine. Participants in wilderness courses feel it is an effective tool and would like to see it used more frequently.

Emergency management of chronic pain and drug-seeking behavior: an alternate perspective.

Pain is one of the most prevalent conditions treated by Emergency Physicians, although it remains contested how to interpret, measure, and treat this condition. In particular, there is controversy over how to identify and treat patients with chronic under-treated pain and those who are potentially malingering (drug-seeking). This article discusses currently accepted paradigms for treating potentially malingering patients, difficulties some communities may have when these paradigms are applied, and the results of implementing pain treatment guidelines that limit opioid use. Systematically limiting opioids via these guidelines was not associated with a decrease in overall patient satisfaction, patient satisfaction with pain management, overall volume, or volume of patients with potential drug-seeking diagnoses. Emergency Physicians' perception of quality of care delivered, as well as job satisfaction, increased after implementation of the guidelines.
