Denver is considered one of the best places to live according to U.S. News & World Report. The following links provide information on local attractions, restaurants, outdoor activities, and sporting events:

University of Colorado Denver (UCD)

The UCD-Anschutz Medical Campus includes the Schools of Medicine, Public Health, Dentistry, Pharmacy, and Nursing, and a Graduate School with doctoral training programs in Basic Sciences, Analytic Health Sciences, and Clinical Sciences. In 2013, UCD researchers received over 500 grants from the National Institutes of Health (NIH) amounting to more than $184 million, making it one of the top ten public universities with NIH support.


Children’s Hospital Colorado (CHCO)

Children's Hospital Colorado is a national leader, ranked 9th in the nation in 2016 by U.S. News and World Report. The main hospital is located on the Anschutz Medical Campus in Aurora with 15 additional community or Network-of-Care affiliations throughout Colorado.  CHCO receives referrals from seven surrounding states. As of 2015, there were 479 beds, ~17,500 admissions, and ~164,000 ER and urgent care visits. The Department of Pediatrics has 724 faculty members with $67 million in external grant funding, including $43 million in NIH funding.

CHCO was awarded the 2015 American Hospital Association-McKesson Quest for Quality Award, for nursing excellence by the Magnet Recognition Program in 2015, and as one of the “10 Best Children’s Hospitals” by Parents magazine.


Fellows will receive comprehensive training and guidance in clinical care, academic scholarship, and education in Pediatric Hospital Medicine. At completion, Fellows will be primed to begin a career in Pediatric Hospital Medicine in academic and/or community settings. Structure and allocation of time for clinical and scholarly pursuits in each year are outlined in the table below, though there is some flexibility depending on the Fellow’s interests. Time allocated to various activities may change as ACGME requirements emerge.

Clinical Care

Fellows receive comprehensive inpatient clinical experience at both our tertiary care and community hospitals. This experience includes attending on the general medical services at Children’s Hospital Colorado and at one or more of the Network of Care sites, which include well newborn and level II NICU management. In addition, Fellows may perform procedural sedation, metabolic lumbar punctures, consultations for surgical patients, and co-management of complex surgical spine patients. Responsibilities include taking call from home and working very few overnight shifts each year.

Fellows will have the opportunity to explore specific areas of interest through clinical electives, including but not limited to:

  • Neonatology & Well Newborn Nursery
  • Anesthesia
  • Intensive Care
  • Pulmonology
  • Gastroenterology
  • Infectious Diseases
  • Acute Pain Service
  • Palliative Care

A supportive faculty will ensure that Fellows thrive throughout their training. The degree of clinical supervision will balance the Fellow’s comfort level, need for autonomy, and patient safety.


Academic Scholarship 

Fellows will have substantial time allocated to developing academic scholarship. Opportunities exist for projects in clinical effectiveness, medical education, translational research, health services research, patent safety, and Quality Improvement (QI).  Our Section of Hospital Medicine has highly qualified mentors with varied interests and expertise (see Mentorship tab). The Section is supported by research coordinators, an epidemiologist, and a survey methodologist.

UCD has additional research support infrastructure, including:


Fellows will be expected to participate in one or more quality improvement initiatives, submit abstracts to conferences, write small grant applications, and begin to submit manuscripts to peer-reviewed journals. Fellows interested in QI have access to Hospital leadership and Process Improvement specialists through the Quality and Patient Safety Department .

To support the development of their academic skills, Fellows can participate in formal training programs. These include the Master’s in Clinical Sciences (MSCS) Program and the Institute for Healthcare Quality, Safety and Efficiency (IQHSE) Certificate Training Program. These programs will be supplemented with a monthly Section of PHM lectures series led by faculty, workshops through the Center for Faculty Development, GME Fellowship Education retreats, monthly work-in-progress sessions, and University-based learning opportunities through the CCTSI. Fellows will be able to attend and present at national conferences, including Children’s Colorado Clinical Concepts & Conundrums in Pediatric Hospital Medicine, Pediatric Academic Societies’ annual meeting, and the Pediatric Hospital Medicine annual meeting. 


Medical Education

Our educational mission is to develop leaders skilled in the education of trainees, patients, families, and the community at large. Fellows will teach a variety of learners while conducting Rounds at CHCO and our community hospitals. They will receive training and support to design educational curricula, present didactic lectures in their areas of interest, and help create clinical pathways. Educational learning opportunities at UCD include:


Fellows can hone their teaching skills through other forums in the Section of Pediatric Hospital Medicine and the Department of Pediatrics:

  • Work-in-Progress Sessions
  • Morbidity and Mortality conference
  • Journal Club
  • Section of Pediatric Hospital Medicine meetings
  • Morning Report
  • Noon Conference
  • Section of Pediatric Hospital Medicine Lecture Series


Department of Pediatrics Fellowship Educational Series: This series was recently developed to address areas of scholarly interest common to all pediatric core fellowships.  Fellows attend 5-6 half-day seminars spread across their Fellowship. In addition to providing core educational material, these sessions allow trainees in different disciplines throughout the department to meet and interact with one another in an informal and collegial environment. Topics for this curriculum: Department of Pediatrics Fellowship Educational Series.

In addition, the Pediatric Educational Excellence across the Continuum and the Council on Medical Student Education in Pediatrics (COMSEP) annual meetings may be of particular interest for rising Medical Educators! 


Administration and Leadership

Trainees in PHM Fellowships are the hospital leaders of tomorrow. Our Fellows will gain experience through leading process improvement teams, collaborating on hospital committees, participating in community outreach programs, and developing clinical pathways. Within the PHM Section, there are notable leaders in administration, medical education, research, and Quality Improvement who will guide Fellows to develop leadership skills and competence (see Mentors tab). Formal avenues of training include People Development at CHCO, which focuses on leadership style and effectiveness, personal evaluation, crucial conversations and communication models; the IQHSE Certificate Training Program; and the Academy of Medical Educators Faculty Development Program.
