Emergency Medicine - Fellowship



The primary focus of our training program is to provide comprehensive training in Pediatric Emergency Medicine (PEM) to allow the graduate to independently manage all problems that would fall under the purview of a Pediatric Emergency Medicine subspecialist.

Fellows rotate primarily through Children’s Hospital Colorado (Children's Colorado) located on the  Anschutz Medical Campus. Children's Colorado is the only free-standing, quaternary care pediatric hospital in Colorado and the only Level 1 Regional Pediatric Trauma Center  in the state with regional referrals from the surrounding 7 state region.  

Learning from direct patient care is augmented by numerous integrated longitudinal curricula involving research, critical appraisal of literature, quality, toxicology, and self-directed and facilitated learning activities.  Our fellows are required to participate in quality projects, lead a scholarship project, and participate in trainee education throughout their fellowship.

Program Aims

  • To produce physicians who are clinically proficient in the practice of pediatric emergency medicine, especially in the management of the acutely ill or injured child, in the setting of an emergency department (ED).
  • To produce physicians who are knowledgeable and have experience in clinical research and research methodology, quality improvement/patient safety, and skills in teaching and life-long learning.
  • To provide useful tools to combat burn-out and encourage wellness and resiliency among trainees, inform trainees of available departmental and institutional resources to address trainee needs.
  • To build and maintain an infrastructure to recruit diverse fellows and provide an inclusive learning environment that promotes and celebrates differences.

Clinical Training

The primary focus of our clinical training is to provide comprehensive training in Pediatric Emergency Medicine (PEM) to allow the graduate to independently manage all problems that would fall under the purview of a Pediatric Emergency Medicine subspecialist.


PEM Clinical


Fellows are directly supervised by Pediatric Emergency Medicine and Emergency Medicine faculty during their clinical ED rotations.  Under the supervision of a large and diverse faculty, trainees gain exposure to patients with a broad spectrum of clinical problems. To prepare trainees to function as effective Pediatric Emergency Medicine subspecialists upon completion of their fellowship, the fellows assume graduated responsibility for patient care over the course of three years.

First Year

During their first year, fellows function as direct care providers, focusing on honing clinical and procedural skills.  In the second half of the year, fellows will have some shifts in which they provide supervision of junior trainees and learn ED management/flow under the direct supervision of a PEM attending. 

The first year for pediatric-trained fellows includes:

For emergency medicine-trained fellows:

Second Year

During their second year, fellows begin the transition from caring for patients directly to becoming the supervising physician in charge of an ED team.  In their second year, the total amount of clinical time decreases compared to year I and fellows assume more teaching and supervisory responsibilities and dedicate more time to scholarship projects.  As part of their clinical requirement, fellows begin “Pre-tending Shifts” where he or she will gradually assume the responsibilities of the Attending ED physician. 

The second year for pediatric-trained fellows includes:

For emergency medicine-trained fellows:

  • Pediatric ED (2 blocks)
  • Research (7 blocks)
  • Elective (2 blocks)

Third Year

During their third year, fellows become proficient in running a large urban, Pediatric ED.  Fellows take primary responsibility for patients, trainees, and other providers on the ED team, referral and transfer calls, and are expected to maintain an effective working relationship and communication with the charge nurse, nursing and ancillary staff. 

The third year for pediatric-trained fellows includes:

  • Pediatric ED (4 blocks)
  • Research (6 blocks, during which fellows have decreased clinical shift load)
  • Adult Emergency Medicine and Trauma month at Denver Health Medical Center (DHMC)
  • Adult ED Point-of-Care Ultrasound at Denver Health (1 month)
  • Elective (1 block)

For emergency medicine-trained fellows:

  • Research (10 blocks)
  • Elective (2 blocks)

The program seeks to provide comprehensive scholarly training that prepares all trainees with the background and skills to compete for academic faculty positions at the completion of their fellowship.

The expectation of this fellowship program is that graduates will have completed a research or complex scholarly project during their three years including presentation of the project at a national meeting, such as the American Academy of Pediatrics fall meeting or the Pediatric Academic Societies spring meeting, and publication of a first author manuscript. Fellows are also required to be involved in QI.

Research Infrastructure

The Section has a full-time research coordinator and biostatistician who are available for assistance with study design, IRB applications, database management, statistical analysis, abstract, and manuscript submission.  Fellows have access to Professional Research Assistants (PRAs) who can help with their research projects by carrying out study enrollment and data collection in the Children’s ED.  PRA coverage averages 10-16 hours per day.

National Research Networks

The University of Colorado Denver/Children's Colorado is a member of PECARN, the Pediatric Emergency Care Applied Research Network. PECARN is a federally funded pediatric emergency medicine research network conducting multi-institutional research on the prevention and management of acute illness and injuries in children and youth of all ages. For more information: http://www.pecarn.org/

Several faculty are members of PEM CRC, the PEM Collaborative Research Committee, a subcommittee of the American Academy of Pediatrics Section on Emergency Medicine. PEM CRC is an unfunded volunteer effort which provides a framework for multicenter investigation. It provides a means of developing protocols and identifying interested co-investigators at over 40 member sites. For more information: http://www.pemcrc.org/ 

Local Research Support 

The Colorado Clinical and Translational Sciences Institute (CCTSI) is a collaborative enterprise between University of Colorado Denver, University of Colorado at Boulder, six affiliated Hospitals and health care organizations, and multiple community organizations with resources to promote research and training that will advance health care and improve the public health. Through the CCTSI, Clinical Translational Research Centers (CTRCs) have been established at several affiliated hospitals, including Children's Colorado, University of Colorado Hospital, and Denver Health Medical Center. The CTRC also offers biostatistical collaboration/consultation for study design, including sample size and power calculations, and data analysis. Children’s Hospital Research Institute also offered limited research support to fellows.


Learning from direct patient care is augmented by a comprehensive series of lectures and conferences focused on Pediatric Emergency Medicine, with the goal to expand clinical knowledge and fine-tune teaching skills.  Fellows have mandatory conference every Thursday that covers broad range of topics.

Introductory Training Program in Quality Improvement

Fellows have the opportunity to apply for an 8-hour session by The Institute for Healthcare Quality, Safety and Efficiency (IHQSE) that covers the importance of quality science in health care, basic tools for analyzing processes of care and identifying opportunities for improvement, fundamental data collection and analysis techniques to support quality improvement projects, methods for creating and testing potential changes, and tactics for implementing and spreading improvement ideas.

Graduate Coursework

Masters of Science in Clinical Sciences (MSCS) program is offered through the university and select fellows through the Department of Pediatrics may apply for limited funding support for this program if grants are available. A mini-certificate or a MPH degree may be obtained at the Colorado School of Public Health (collaboration between University of Colorado Denver, Colorado State University and the University of Northern Colorado). For more information: www.publichealth.ucdenver.edu  . The certificate program requires 15 hours of graduate work and the MPH requires 42 hours of graduate work. This requires extra time commitment as the clinical and elective requirements remain unchanged. Funding for trainee graduate coursework is not supported by the section of emergency medicine.

Scientific Meetings and Other Conferences

Pediatric Emergency Medicine fellows are encouraged to attend national scientific meetings throughout their fellowship. If funding is available, the Section supports travel to any national meeting for which the trainee has an abstract or platform presentation according to section rules, as well an additional career-focused conference for networking during their 2nd or 3rd fellowship year.

    Diversity / Equity / Inclusion


    We are committed to creating a diverse environment for students, residents, fellows, and faculty. We believe that an environment of inclusiveness and respect promotes excellence and that a setting where diversity is valued leads to the training of physicians who are prepared to practice culturally effective medicine and meet the needs of the various populations we serve. Visit our Diversity, Equity, and Inclusion webpage for more....

    Well-Being / Resilience

    Be well

    By embracing wellness and improving personal resiliency, physicians can reconnect with the meaning of their work and fend off stress. Reducing or eliminating burnout also has practical implications for the entire department such as improving patient safety, student advancement, and the overall campus environment.
