WMed Provides Medical Control to America’s First National Park

Yellowstone National Park was established in 1872 as the world’s first national park. At over 3,400 square miles, Yellowstone has an area larger than the states of Rhode Island and Delaware combined. Yellowstone’s beauty and unique geology includes 290 waterfalls, more than 500 active geysers, more than 10,000 hydrothermal features, and over 1,000 miles of backcountry trails coupled with extensive wildlife, including bears, moose, elk, bison and wolves. The park typically attracts 4 million visitors per year. Considering the park’s size, large number of visitors, and unique and common health hazards, the need for an effective EMS system is immense.

Yellowstone EMS is a complex, high performing system that includes both basic and advanced life support (ALS) National Park Service personnel. The park maintains 10 ALS ambulances and two non-transporting ALS units, with essentially all law enforcement rangers carrying either BLS or ALS equipment. Yellowstone EMS responds to more than 1,000 EMS incidents annually involving a wide variety of typical and unusual clinical conditions. The latter include trauma from thermal features, wildlife encounters, and backcountry injuries along with complex search-and-rescue operations. Because of the remote location of the park, one of the many challenges is long transport distances to definitive medical care facilities. For example, ground transport from the five park entrances to the nearest Level 2 trauma centers range from 109 to 175 miles, or two to three hours. Despite this, Yellowstone EMS is able to provide high-performing pre-hospital care, achieving excellent patient outcomes that rival many urban EMS systems.

In 2020, leaders from the Division of EMS and Disaster Medicine at WMed began working collaboratively with Will Selde, MD, who completed his Emergency Medicine residency training at WMed in 2013, to provide EMS medical control and direction for Yellowstone. Dr. Selde is a fellowship-trained EMS physician, a clinical assistant professor of Emergency Medicine at WMed and is board certified in Emergency Medicine and EMS. Dr. Selde now practices in Wyoming but continues to regularly return to Kalamazoo to teach WMed students, residents, and fellows and to collaborate with other faculty on EMS research. Dr. Selde serves as the primary Medical Director to Yellowstone and works in collaboration with WMed faculty, fellows, and residents from the Department of Emergency Medicine to provide 24/7 medical control consultations and direction, assist with on-site continuing education, and participate in a robust quality improvement program.

Dr. Tim Schiller, a third-year Emergency Medicine resident, recently completed the Yellowstone elective.

WMed is uniquely positioned to provide high-quality EMS medical control services to Yellowstone, despite the distance. WMed is one of only two Emergency Medicine residency programs in the nation to maintain a 24/7/365 on-call Emergency Medicine resident physician or EMS fellow who provides medical control to EMS units. Our residents and fellows are supervised by on-call Emergency Medicine faculty. Medical control consultations from Yellowstone are routed to the on-call EMS physician through our county/regional MEDCOM Center, operated by West Michigan Air Care. A newly acquired, sophisticated recording system allows for effective case reviews of communications between EMS field personnel and medical control physicians.

As our relationship with Yellowstone develops, we are excited about the potential to develop additional educational and research opportunities for WMed students, residents, and fellows. 

The WMed Division of EMS and Disaster Medicine is honored to be entrusted with the responsibility of providing medical control and supporting the efforts of National Park Service EMS personnel  to deliver high-quality emergency medical care to the visitors and residents of America’s oldest national park.


  • Why did you choose to participate in the Yellowstone elective?
    • I chose to participate in Yellowstone because of my Interest in EMS, wilderness medicine and of course because it's Yellowstone. - Tim Schiller, MD (PGY-3)
    • I chose to participate in the elective because of my interest in EMS and wilderness medicine. Plus, who wouldn't want to spend a couple weeks in Yellowstone National Park?! - Alexandra Dinello, MD (PGY-3)
    • I chose to participate in the Yellowstone elective because of my interest in the outdoors as well as EMS. It requires many skills we learn in Emergency Medicine to be applied in austere environments. It also provides for a once in a lifetime experience and is an elective that lets you get “outside” of the hospital and do something unique while in residency. - Charles Brauchla, MD (PGY-3)
  • What was your favorite thing about the experience?
    • Working with the park rangers daily was great, and being able to take EMS calls at any time was exciting. Other great thing is there is always time to explore the park both while working. - Tim Schiller, MD (PGY-3)
    • My favorite thing about this experience was getting to know all of the amazing people at YNP. I got to spend a lot of time with Joe Beuter who is a ranger/paramedic/firefighter/LE officer who is possibly one of the most interesting (and hilarious) people I have had the privilege to work with. - Alexandra Dinello, MD (PGY-3) 
    • Being able to apply EM skills outside of the hospital and work with the rangers on a daily basis was great. Responding to calls whenever you want is similar to being on MSU-1, our physician response vehicle, but in a much more remote area. Having plenty of time to explore the park is certainly a perk as well. - Charles Brauchla, MD (PGY-3)
  • Were you involved in any especially interesting calls?
    • I went on a couple medical transports (acute abdominal pain and respiratory distress) from Mammoth to the local hospital in Livingston and responded to a scene call where a car had driven off a cliff (amazingly, no injuries!). You do carry around a radio and pager and can respond to pretty much anything that interests you. While I was there was a thermal burn in the Old Faithful area and an active SAR effort elsewhere in the park. - Alexandra Dinello, MD (PGY-3) 
    • I had a few typical MVC’s, a heart block, and there was a cardiac arrest as well. After I left there were a few thermal burns within the next couple of weeks that I wasn’t able to experience. - Charles Brauchla, MD (PGY-3)
  • What education did this provide that was not possible to receive in Kalamazoo?
    • Being part of a very rural EMS system was very educational, it's always hard to imagine what EMS is going through prior to reaching the hospital, but to be with a group that is with a potentially critical patient for hours at a time was very eye opening. - Tim Schiller, MD (PGY-3)
    • The Yellowstone elective is a unique opportunity in that you get to see how the National Park Service operates. There are some opportunities for technical SAR training (such as high angle rescue) depending on what time of the year you go. The rangers and other medical personnel are happy to have us there and have no shortage of stories and expertise to share. - Alexandra Dinello, MD (PGY-3) 
    • In the majority of populated areas in the United States, transport times for EMS are quite short. Experiencing a rural EMS system where transport times are often measured in hours, not minutes, allows us to be with patients for much longer periods of time. It requires learning about when helicopter transports are necessary in these rural areas. It also allows us to work with much more limited resources than in large tertiary care centers where EM residencies are located. - Charles Brauchla, MD (PGY-3)
