Pediatric Critical Care Medicine Fellowship


“We believe in the spirit and resiliency of the children entrusted to our care, and we will relentlessly push the field of critical care forward to ensure we find even better ways to treat them"



The Section of Pediatric Critical Care Medicine (PCCM) and the Department of Pediatrics at the University of Colorado School of Medicine (CU SOM) offer a fully accredited pediatric critical care fellowship for up to 9 fellows at a time (average 3 per year) designed for board-eligible pediatricians planning a career devoted to the care of the critically ill child.  Our program mission is to train the future leaders of pediatric critical care, who will provide compassionate and high-quality care and contribute to the advancement of critical care medicine.  To achieve this mission, we have the following:


Program Aims

  1. To prepare physicians to provide high quality, patient-centered, and comprehensive care for critically ill pediatric patients and their families using an interdisciplinary team approach.
  2. To provide outstanding opportunities to engage in a range of scholarly activities that promote lifelong learning, reflective practice, critical thinking, and discovery, advancing the field of pediatric critical care medicine. 
  3.  To develop effective educators of learners with variable backgrounds and needs, including patients and families. 
  4. To promote longevity within PCCM practice by teaching strategies to maintain wellness, build resilience, and minimize burnout.   

The PCCM fellowship program offers broad-based training in both the practice of pediatric critical care medicine and the advancement of scholarship related to pediatric critical care. The section of PCCM consists of 20 faculty, all board certified or board eligible in pediatric critical care medicine, with two dual-boarded in pediatric pulmonology, four full-time PhD investigators and 16 advanced practice practitioners (PA/NP). In addition, several members of the Departments of Pediatric Pulmonology, Cardiology, and Anesthesiology provide key roles in the education and training of the fellows.


The primary clinical training site for the fellowship is the Children's Hospital Colorado, a free-standing children's hospital affiliated with the University of Colorado School of Medicine.  The 32-bed Pediatric Intensive Care Unit (PICU) admits approximately 2,600 patients per year from the Denver metro area and surrounding Rocky Mountain Region, serving active programs in pediatric general surgery, trauma surgery, solid organ and bone marrow transplantation, ENT, and orthopedic surgery.  In addition, there is a separate Cardiac Intensive Care Unit (CICU) providing care to cardiology and cardiac surgery patients.  PCCM fellows participate actively in the multidisciplinary teams responsible for the care of every patient in the PICU and the CICU.


Clinical Education


First Year

The first year is designed to provide the fellow trainee with the necessary experience to become an excellent clinician and teacher in the field of critical care medicine. The year is fully structured and almost entirely clinical. The required clinical rotations include:

  • Seven months of clinical service in the ICU, on both the pediatric ICU (5 months) and cardiac ICU (2 months) services. Fellows are primarily responsible for all medical patients in the PICU, and they co-manage all surgical patients.

    One month of pediatric anesthesiology in the first half of the year; this is designed to teach airway management, intubation, vascular access, and sedation skills.

    One month on the pediatric pulmonary medicine service at Children's Colorado. Fellows gain bronchoscopy experience during this month, as well as a broader view of pediatric pulmonary disease.


    Second and Third Years

    The educational goal of the second and third year clinical rotations is to solidify the knowledge and skills attained during the first year, and to develop their leadership, team management and supervisory skills.  The expectation is that fellows will have increasing independence through these years. The required rotations during the second and third years include:

    • 3 – 4 months of clinical service in the ICU, on both the pediatric ICU (2 – 3 months) and cardiac ICU (1 month).


    All Years

    In addition to the clinical rotations, the PCCM fellows at the University of Colorado receive the following educational opportunities:

    • Multi-disciplinary high-fidelity simulation experiences through the CHCO simulation center
    • Ultrasound-guided point of care procedure training
    • Weekly divisional educational conferences
    • Monthly Evidence-Based Medicine conference
    • Monthly Morbidity & Mortality and Quality, Safety and Practice Council conferences
    • Departmental Fellows Core curriculum, which covers topics relevant to all pediatric fellows, including Evidence-Based Medicine, Quality Improvement and Safety, Ethics, Communication, Teaching, Mentoring, Scientific Writing and Career Development

    Fellows participate in Children's Hospital Emergency Transport Service and manage, with supervision from the ICU attending, transports and admissions to the PICU.  Night call is taken in-house and averages every 5-6 nights.  At least one PICU attending is in-house 24 hours a day, 7 days a week, to ensure a safe balance between clinical demands and educational needs of the fellows.


    Clinical Electives


    PCCM fellows at the University of Colorado School of Medicine have the additional opportunity to participate in two structured clinical electives during their second or third year:

    An international cardiac intensive care elective with one of our PCCM faculty, Dr. Vohwinkel, through the International Children’s Heart Foundation

    An elective at Denver Health Pediatric Intensive Care Unit, affiliated with the University of Colorado, which offers the opportunity to practice in a smaller community-based PICU under the supervision of board-certified PICU faculty.



    Research/Scholarly Activity


    Numerous funded academic and research opportunities are available to critical care fellows. This includes but is not limited to basic science and translational research in pulmonary vascular disease, developmental lung biology, oxygen radical-induced injury, biomechanical engineering, and neuro-trauma. Clinical research is supported through an active and growing critical care research program, and outcomes-based research and quality improvement projects are also available to interested fellows.

    The research portion of the Pediatric Critical Care Medicine Fellowship occurs all three years, with 2 months in the first year and 7 – 8 months the second and third years. During this time, fellows will be expected to engage in scholarly projects that require critical thinking and to acquire the knowledge and skills for advancing the field of critical care.  The scholarly activity will be performed under the guidance of a research mentor and team, who will be identified during the first year of fellowship. Fellows will be expected to disseminate their findings at national scientific meetings and within peer-reviewed journals.

    The Application Process

    Nationally, Pediatric Critical Care Fellowship programs use the ERAS application system.  For our program the application period will begin July 15, 2018.  Completed ERAS applications are screened and selected applicants are invited to travel to Denver to meet with faculty, fellows and tour our facilities.  The selection criteria are based on prior academic performance, the strength of clinical training and performance, and scholarly interests and pursuits.  Letters of support from PCCM supervising physicians are strongly recommended.  Our interview season begins in August and ends in November of 2019.

    Fellow selection is accomplished by participation in the National Residency Matching Program Match service, which occurs in the fall each year. Applicants must be eligible for a Colorado medical license. International medical graduates must have a valid ECFMG (see below)
