Immediate Past President
John Christensen, MD FAAEM

Dr. Christensen entered Oakland University in Rochester, MI at the end of his high school junior year and received a B.S. degree in Engineering Science, with Student of Distinction Honors. He then attended medical school at the University of Michigan, where he received his M.D. degree and worked as an engineering research assistant at U of M’s Highway Safety Research Institute. He completed an Internal Medicine Residency at University of Michigan Hospitals.

Dr. Christensen moved to Santa Cruz, CA in 1976 and received an appointment as an Assistant Professor of Community and Family Medicine at UCSF’s Family Practice Residency in Salinas, where he was an attending physician in an ED staffed by one of the original EM contract management groups in the state. Sensing an unfair business arrangement, he approached the Monterey County Controller for financial information on the ED contract, sought legal advise on the restrictive covenant protecting the contract and was ultimately able to convince the County’s General Counsel that an independent EM group could do a better job than the contract management group (CMG) that he believed was managing its affairs in a manner that was detrimental to the ED physicians. Thus was born the first independent EM group in California where a democratically oriented local group of physicians was able to defeat a large CMG and establish an entity based on fair business practices.

With the experience gained in Salinas, Dr. Christensen joined with other EPs in 1983 to staff a large community hospital in Santa Cruz. The group incorporated as Santa Cruz Emergency Physicians (SCEP) in 1992 and became recognized as a model for fairness-based governance and operations. In 1991, newly minted Catholic Healthcare West (CHW) acquired the hospital served by SCEP. CHW expanded rapidly to become the eighth largest hospital system in the country, and in 1997attempted to launch a plan with the potential to place over 500 emergency physicians and ultimately several thousand hospital-based physicians into a vertically integrated, corporate-controlled fee splitting arrangement. Dr. Christensen led the 4-year strategic planning and forensic financial analysis that drove the largest legal action in emergency medicine’s history centering on the fair market value of emergency medicine management services. AAEM played a vital role in supporting the California Medical Association (CMA) amicus curiae brief (available on the AAEM website) that tipped the balance and led to the dissolution of the management scheme at the heart of the fee-splitting arrangement targeted by the historic declaratory relief action. The CMA brief represented the California Medical Association, the California Society of Anesthesiologists, the California Radiology Society, AAEM, CAL/AAEM and the California Society of Pathologists. Hospital Based Physicians’ income and professional autonomy have been preserved at CHW sites across the state to this day, and other hospital systems were probably dissuaded from attempting similar arrangements. In 2003, AAEM gave Dr. Christensen the James Keaney Leadership Award for his role in the complex legal action.

Through years of arduous, high-risk battles to preserve fairness and due process, Dr. Christensen is deeply committed to advancing AAEM’s Mission. Dr. Christensen has proposed the formation of an AAEM Business Practice Valuation Council that establishes AAEM as the Trustee of Fairness in the Business of EM. Dr. Christensen has recently completed the draft version of an EM Practice Valuation Toolkit that will be available to all AAEM Members to inform their critical decisions on employment arrangements and other business matters.

At-Large Board Member
Scott D. Reiter, MD FAAEM

Emergency Medicine and S.D.R.: “The In-A-Nutshell” - I grew up in a rough suburb of Newark where I learned to fight and became very familiar with my local emergency department. That is what drew me into emergency medicine initially. If I was going to spend so much time in the ER, I really should be getting paid for it.

After four years undergraduate at Johns Hopkins University, I went to my state medical school which was UMDNJ-Rutgers Medical School in Piscataway and New Brunswick, currently Rutgers – Robert Wood Johnson Medical School. I was lucky to do an eight week externship at MIEMS – Adult Shock Trauma at the end of 1978 after being invited there by R Adams Cowley, M.D., a thoracic surgeon I had written to amazed by his approach and results. He lowered the mortality from 80% to 20% in multi-organ trauma including patients in neurological and systemic shock. I stayed an additional eight weeks in Baltimore with J. Alex Haller, a skilled pediatric thoracic surgeon who recently died. His team treated the region’s pediatric trauma at Johns Hopkins Hospital’s Harriet Lane via the Pediatric ER.

When I applied for an Internal Medicine Residency at LAC/USC Med Ctr, there was no ABMS recognized specialty of Emergency Medicine or Board Exam. I did an extra (chief resident) year with 6+ months of electives more useful for emergency practice while moonlighting in all the emergency areas including 1350 MAR, 1060 surgical walk-in and 1050 med walk-in. After completing my extra year of residency, I stayed on at LAC/USC accepting staff assignments in these same areas.

Meanwhile, I became the Base Station Director and Paramedic Liason Physician at Beverly Hospital in L.A. and Attending Emergency Physician at Hollywood Presbyterian (One of the busiest private trauma centers in L.A. from 1984 to 1987). I have worked many settings including an eight year part-time stint at Kaiser Permanent ER in W.L.A., the ER in Marina del Rey, University of CA – L.A. starting as a Visiting Instructor in Emergency Medicine in 1987 to just recently, a nine year stint part-time at Olive View – U.C.L.A. Med Ctr and others. At age 65, I have paired down my Emergency Shifts and find myself more concerned with helping the practicing Emergentologist than the patient in the E.D. Helping with physician wellness can have an amplified ripple effect that helps many times the number of patients that I could manage. I have gone from gaining satisfaction as a “rescuer” to a more rewarding “rescuing the rescuer”. I hope that my role on the CAL/AAEM Board of Directors can help. I want anyone to feel free to write me and join me on my quest to make Emergency Practice Great Again. <- Just Kidding. But we need to ensure that ER Docs rights don’t erode, and the practice environment is optimized for patient care, not profits. Healthy Emergency Physicians practice better and longer. We deserve to practice in environments where we thrive. Patients are the ultimate benefactors.
