Overview and Mission
Division of Critical Care Medicine | Pediatric Critical Care Medicine Fellowship Program
Critical Care Medicine Graduation Ceremony, June 2024; Harvard Club, Boston, MA
Welcome from Program Director, Traci Wolbrink, MD, MPH
Welcome to the site for the Boston Children’s Hospital/Harvard Medical School Critical Care Fellowship Program.
We are currently an 18-fellow program representing a talented group of physicians from a diverse range of backgrounds.
The fellowship program was established in 1981 with the primary objective to prepare fellows for a successful academic career in pediatric critical care medicine. Comprehensive clinical skills are developed in the Medical-Surgical, Cardiac, and Medicine Intensive Care Units, complemented by rotations in anesthesiology, neurointensive care, transport medicine and extracorporeal membrane oxygenation (ECMO) therapy. Scholarly activity is also completed throughout all three years of training with guidance from the Scholarly Oversight Committee (SOC).
Our educational vision for fellows training in our program is comprised of the following:
- To acquire the knowledge, skills and experience to comprehensively care for the critically ill or injured child and to successfully execute this care in a multidisciplinary intensive care unit
- To develop teaching skills necessary to share knowledge and experience to a multidisciplinary and multilevel audience in a variety of formal and informal settings
- To establish and develop a unique academic focus that leads to scholarly productivity and opportunities to advance the field of pediatric critical care medicine
- To participate in and develop leadership and administrative skills in both the clinical and non-clinical settings
We are committed to providing fellows with the experience, mentorship and support needed to develop a successful career.

Curriculum and educational highlights
Educational Curriculum
Our critical care fellows develop a strong, broad-based foundation of knowledge and skills in pediatric critical care, academic medicine, and leadership. This is achieved both through clinical roles working together with faculty and other members of the multidisciplinary team to provide high-quality direct clinical care, and engagement in a diverse curriculum that utilizes a variety of educational approaches. We are fortunate to have many dedicated clinician-educators and unique resources that allow us to develop and deliver high-quality bedside, simulation-based and online learning experiences. All our critical care faculty are active participants in delivering the curriculum, many elements of which are exclusively provided for our fellows. Our fellows have an active role in the planning and delivery of the curriculum. Our fellows present at and lead Division conferences and provide teaching experiences for medical students from Harvard Medical School and pediatric residents from the Boston Combined Residency Program in Pediatrics.
Some of our core conferences noted below:
- Fellows’ colloquium lecture series
- Ultrasound Curriculum
- Fellow procedural curriculum
- Simulation curriculum series
- CICU lecture series
- MSICU Case Conference
- Neurocritical Conferences
- ECMO conference series
- Research and clinical protocols
- Evidence based medicine series
- Mortality conferences
- Morbidity conferences
- Topics in Anesthesia lecture series
Clinical experience for fellows
Clinical Experiences for Fellows
Fellows in their first year, undergo clinical training in all three intensive care units, the
operating room and subspecialty rotations to expose Fellows to the full range of critically ill
patients. First-year Fellows spend time in the operating room specifically to accumulate airway,
vascular access, procedural and perioperative experience. In the second and third years of
training, Fellows assume progressively more responsibility and autonomy, leading work
rounds and overseeing the function of the ICU throughout the day and night.
Scholarly activity and academic highlights
Scholarly Activity and Academic Highlights
Directly adjacent to the Boston Children’s Hospital main campus, Harvard Medical School
offers an incredible variety of research and service opportunities created by the unique
synergy between HMS, our many Boston-based affiliate institutions, MIT, and renowned
partner institutions around the world. The scientific environment at Boston Children’s Hospital is highly conducive to fostering successful physician-scientists.
Each year, our fellows are paired with mentors within and outside our division for their Scholarly activity for fellowship and hopefully for career-long working relationships. A map of their time with us is developed, and over the course of their fellowship, a research project is completed. Our fellows benefit from mentors who have experience in this particular role and are eager to help fellows reach their next research milestone.
Our fellows are overseen by multiple layers to ensure their academic success including our program director, Traci Wolbrink, our program associates for research, Jennifer Perez and Gregory Priebe, and their individual Scholarly Oversight Committee assigned to each fellow.
For more details on scholarly requirements for board eligibility, please see the American Board of Pediatrics General Criteria for Subspecialty Certification.
