The Wilderness Medical Society (WMS) convened an expert panel in 2011 to develop a set of evidence-based guidelines for the recognition, prevention, and treatment heat illness. current retained 5 original members welcomed 2 new members, all whom collaborated remotely provide updated review classifications, pathophysiology, planning preventive measures, recommendations field- hospital-based therapeutic management These are graded based on quality supporting evidence balance between benefits...
The purpose of the study was to evaluate prevalence acute kidney injury (AKI) during a multi-stage ultramarathon foot race. A prospective observational taken Gobi 2008; Sahara and Namibia 2009 RacingThePlanet 7-day, 6-stage, 150-mile ultramarathons. Blood analyzed before, immediately after stage 1 (25 miles), 3 (75 5 (140 miles). Creatinine (Cr), glomerular filtration rate (GFR), incidence AKI were calculated defined by RIFLE criteria. Thirty participants (76% male, mean age 40 + 11 years)...
Background Despite concerns that non-steroidal anti-inflammatory drugs (NSAIDs) contribute to acute kidney injury (AKI), up 75% of ultramarathon runners ingest these during competition. The effect NSAID on AKI incidence in is unclear. Methods Multisite randomised double-blind placebo-controlled trial the Gobi, Atacama, Ecuador and Sri Lankan deserts determine whether ibuprofen (400 mg every 4 hours) would be non-inferior placebo a 50-mile (80 km) foot race. primary outcome was defined as...
Introduction: Mandated patient surveys have become an integral part of Medicare remuneration, putting hundreds millions dollars in funding at risk. The Centers for & Medicaid Services (CMS) recently announced a experience survey the emergency department (ED). Development ED Fast Track, where lower acuity patients are rapidly seen, has been shown to improve many metrics that CMS examines. This is first study examining if Track implementation affects Press-Ganey scores satisfaction.Methods: We...
Determine prevalence, incidence, and risk factors of acute kidney injury (AKI) during multistage ultramarathons.Prospective observational cohort study.Jordanian Desert 2012; Atacama Desert, Chile 2012 2013; Gobi 2013 RacingThePlanet 250 km, 6-stage, ultramarathons.One hundred twenty-eight participants (384 measurements) from the Jordan (25, 19.5%), (35, 27.3%), (24, 18.8%), (44, 34.4%) races.Blood samples weights were gathered analyzed immediately after stage 1 (40 km), 3 (120 5 (225...
Objectives Elevated optic nerve sheath diameter on sonography is known to correlate with increased intracranial pressure and observed in acute mountain sickness. This study aimed determine whether changes ascent high altitude are associated sickness incidence. Methods Eighty‐six healthy adults enrolled at 1240 m (4100 ft), drove 3545 (11,700 ft) then hiked slept 3810 (12,500 ft). Lake Louise Questionnaire scores measurements were taken before, the evening of, morning after ascent. Results...
Background: Acetazolamide is the most common medication used for prevention of acute mountain sickness (AMS), usually administered day or night before ascent. The objective this study was to evaluate efficacy ascent dosing acetazolamide AMS prevention. Methods: Double-blind, randomized, controlled noninferiority trial 125 mg twice daily beginning either morning Healthy low altitude adults ascended from 1240 m (4100 ft) 3810 (12,570 during summer 2018 on White Mountain, California.

Wilderness medicine is the practice of resource-limited under austere conditions. In 2003, first wilderness fellowship was established, and as March 2013, a total 12 fellowships exist. 2009 American College Emergency Physicians Medicine Section created Fellowship Subcommittee Taskforce to bring together directors, associate other interested stakeholders research develop standardized curriculum core content for emergency (EM)-based fellowships. This paper describes process results what became...
