Neonatal-Perinatal Fellowship Program

The Neonatal-Perinatal Fellowship Program at Children's Hospital of Philadelphia is a comprehensive three-year fellowship aimed at developing outstanding clinicians with solid background in physiology, pathophysiology and evidence-based practices in neonatology; providing a high-quality scholarly experience; and promoting an academic career in neonatology.

The history, expertise and compassion that make Children’s Hospital of Philadelphia unique are also what makes it the best place for medical trainees.

Clinical training environments

Neonatal fellows train in a number of clinical environments across three institutions, giving them the opportunity to learn not only from a large faculty of neonatologists but also from the subspecialists involved in the care of neonatal patients. See below for brief descriptions of the clinical sites where fellows rotate.

CHOP Newborn/Infant Intensive Care Unit (N/IICU)

The Harriet and Ronald Lassin Newborn/Infant Intensive Care Unit (N/IICU) at CHOP is a 100-bed level 4 neonatal/infant ICU with an average daily census of 100. We also have a 10-bed step-down unit for convalescing neonates and infants. We have over 1300 admissions a year which includes neonates with known congenital anomalies born in the Special Delivery Unit at CHOP, referrals from regional NICUs, and admissions from the emergency department. Patient complexity and acuity is extremely high with an average of 35-40 patients on invasive ventilation daily and over 30 ECMO patients a year. Our neonatal ECMO program has one of the highest volumes in the nation.

The medical teams provide care to a wide variety of patients with complex medical needs, each team caring for 12-16 patients. Our Chronic Lung Disease Program provides multidisciplinary care to patients with the most severe form of this neonatal morbidity. Additionally, we have a large population of patients with primary surgical disease cared for by the Neosurgery Team – a longstanding collaboration between neonatologists and surgeons that has an average census of 30.

The N/IICU is organized into 6 medical teams. Each team has a dedicated social worker, discharge planner, and dietician. The teams have access to an outstanding group of clinical pharmacists, psychologists, physical therapists, and speech therapists. We also benefit from the existence of a number of collaborative programs for subspecialty care featuring unique expertise and a remarkable array of technical and diagnostic capabilities. These include the Neonatal Craniofacial Program, the Neonatal Airway Program, and the Neonatal Neurocritical Care Program. Our unit provides training to pediatric residents, neonatology fellows, pediatric surgical fellows, nurse practitioner students, and hosts one of the only neonatal physician assistant residencies in the country.

Neonatal Follow-up Clinic

Neonatal fellows will spend a minimum of one month of their fellowship training in the Neonatal Follow-up Clinic on the main campus at CHOP. During this time, they will see graduates of the CHOP N/IICU and HUP Intensive Care Unit as well as other patients at high risk for neurodevelopmental delay. The clinic sees patients from early childhood through to school age (0-5 years). Fellows rotating in this transdisciplinary clinic work closely with neonatologists focused on follow-up care, developmental pediatricians, physical/ occupational therapists, and psychologists. They will observe psychological testing and gain an understanding of the ways in which neonatal outcomes are evaluated both clinically and in the conduct of randomized trials, which inform evolving clinical care. This experience will also give fellows insight into what life is like for families after discharge from the NICU, improving their ability to understand the life-course of NICU graduates and counsel families before and during NICU admissions. For fellows intending a career integrating follow-up, clinical time can be modified to include more time in the follow-up clinic, and many prior fellows have pursued quality improvement and research projects focused on neonatal follow-up.

Special Delivery Unit / Center For Fetal Diagnosis And Therapy (SDU/ CFDT)

The Garbose Family Special Delivery Unit (SDU) is the world’s first birth facility in a pediatric hospital specifically designed for healthy mothers carrying babies with known birth defects. Located within the Children’s Hospital's Richard D. Wood Center for Fetal Diagnosis and Therapy (CFDT), neonates are immediately resuscitated and transferred to either the  N/IICU or the  Cardiac Intensive Care Unit for ongoing care.

Over 500 deliveries occur in the SDU each year, where fellows have the opportunity to work with and learn from maternal fetal medicine specialists, fetal and pediatric surgeons, fetal cardiologists, and neonatologists. Fellows are involved in the resuscitation of neonates born with congenital defects including congenital diaphragmatic hernia (CDH), congenital heart disease, omphalocele, gastroschisis, myelomeningocele, sacrococcygeal teratoma, lower urinary tract obstruction, and congenital pulmonary airway malformation, among various other diagnoses. The CFDT also has a busy perinatal palliative care program. Fellows are involved in the prenatal consultations and delivery room plans with a perinatal psychologist.

The CFDT is a world leader in ex utero intrapartum treatment (EXIT) procedures and fetal surgery including fetal myelomeningocele repair, lung lesion resection, FETO (fetal tracheal occlusion for CDH), sacrococcygeal teratoma resection, and fetoscopic selective laser ablation for twin-to-twin transfusion syndrome. Following delivery, fellows have the opportunity to care for neonates with primarily surgical diagnoses on the Neonatal Surgical Team, jointly managed by neonatologists and pediatric and fetal surgeons. The CDH Frontier program has allowed for exciting advances in both the clinical care of babies with CDH and research. Our unit cares for roughly 40-50 infants with CDH per year. Fellows actively participate in the surgical plans and procedures and gain exposure to a high volume of extracorporeal membrane oxygenation (ECMO). This unique population also provides ample opportunities for research and mentorship. 

Cardiac Intensive Care Unit (CICU)

The Daniel M Tabas Cardiac Intensive Care Unit (CICU) has 32 beds with an average census of 28 patients/day, and approximately 900 cardiothoracic surgeries are performed each year. The patients are divided into 3 teams supervised by cardiac care intensivists and cardiothoracic surgeons. Front line care is provided by PICU, cardiology, and NICU fellows, nurse practitioners, physician assistants, and hospitalists. Patient care is coordinated with a multidisciplinary team consisting of nurses, dieticians, pharmacists, social workers, case managers and other subspecialists. NPM fellows will spend 4 weeks in the CICU and will have exposure to preoperative and postoperative management of congenital heart disease, acute and chronic heart failure, arrhythmias, myocarditis/cardiomyopathy, mechanical circulatory support, and heart/lung transplantation.

Hospital Of The University Of Pennsylvania Intensive Care Nursery (ICN)

The Hospital of the University of Pennsylvania (HUP) is located adjacent to CHOP in University City. HUP has an average of 4200 deliveries a year, with an active Maternal Fetal Medicine program. The Intensive Care Nursery (ICN) is a level IIIB NICU and admits, on average, 700 infants per year, including 120 very low birth weight infants, with an ICN average daily census of 36. Fellows rotate here during all three years of their fellowship and gain an invaluable experience in bread and butter neonatology, delivery room management, and the teaching and supervision of trainees.

Teams consist of neonatologists, pediatric residents, neonatal nurse practitioners, physician assistants, medical students, nurses, respiratory therapists, pharmacists, dieticians, occupational and speech therapists, and social workers. The ICN provides comprehensive care for a wide variety of complex infants including those requiring therapeutic hypothermia and video EEG, echocardiography, all modes of radiographic assessment, and ophthalmologic intervention. The ICN supports infants who need ventilation with high frequency oscillatory and jet ventilation, as well as inhaled nitric oxide. On-site subspecialty consultation is provided by CHOP subspecialists.

NICU fellows at HUP have the opportunity to provide prenatal consultation, to lead a multidisciplinary team on rounds and in the delivery room, all with close support of the attending physician. In the HUP ICN the NICU fellow gets a graduated level of autonomy in patient care as he/she progresses through fellowship, and leadership skills are cultivated here. There is a robust Quality Improvement program at HUP that encourages fellow involvement, as well as many opportunities to be involved in resident education, simulation, and perinatal research.

Pennsylvania Hospital Intensive Care Nursery (ICN)

Pennsylvania Hospital, the oldest hospital in the United States, is located in Center City Philadelphia, 2.5 miles east of CHOP. It features a 50-bed level 3B NICU staffed by physicians, nurse practitioners and physician assistants. Pennsylvania Hospital has an average of ~5000 deliveries a year, ~1000 admissions a year to the ICN, and an ICN average daily census of 35. Senior fellows rotate here during their second year, when they are able to solidify their skills in the care of preterm infants and gain valuable experience leading an interprofessional team at a high-volume delivery center.

Teams consist of neonatologists, front-line care providers, nurses, respiratory therapists, pharmacists, dieticians, occupational and physical therapists, psychologists, and social workers. The ICN provides comprehensive care for a wide variety of complex infants including those requiring therapeutic hypothermia, echocardiography, all modes of radiographic assessment, interventional radiology, and ophthalmologic intervention. On-site subspecialty consultation is provided by CHOP/Penn Endocrinology, Genetics, Neurology, Cardiology, Orthopedics, ENT, Plastic Surgery and Ophthalmology.

In addition to NICU fellows, medical students, NNP students, physician assistant residents, pediatric residents, and CHOP Hospitalist Medicine fellows can all opt to rotate through the Pennsylvania Hospital ICN. The rotation offers NICU fellows the opportunity to train in a third clinical environment to increase the exposure fellows have to various neonatology practice models and patient populations. Fellows participate in prenatal consultations, delivery room resuscitations, and patient care in the ICN while gaining valuable leadership skills, working side-by-side with the ICN staff.

Scholarship pathways and research education

Research education is a major focus of the Neonatal-Perinatal Medicine Fellowship Program. Fellows have ample protected time throughout their fellowship to participate in rich and rewarding academic experiences.

There are many ways to shape a productive, academic career. A career as an independently funded physician scientist (bench or clinical) has historically been the most traditional path for an academic neonatologist. However, we recognize that there are many additional paths to build a successful and rewarding academic career. To ensure fellows get the most out of their time in fellowship and start building the tools necessary to embark on a career within their chosen academic focus, our fellows participate in Scholarship Pathways to promote individualized professional development. Tailored to meet every fellow’s unique scholarly interests, these pathways can accommodate fellows interested in Basic Science, Clinical Research, Translational Research, Bioethics, Medical Education, NICU Follow-Up, NICU Administration, QI/Patient Safety/Implementation Science, Bioinformatics, and Clinical Programmatic Development. Each pathway will provide individual fellows with unique opportunities to develop skills and expertise within a given academic niche. Specific mentors within the Division of Neonatology will oversee a fellow’s professional development and progress along his/her chosen scholarship pathway. Regardless of what pathway is chosen, all fellows complete a high quality, in-depth scholarly activity that furthers a fellow's career development and aligns with their scholarly interests.

While fellows pursue individualized research projects, all participate in a comprehensive research education program that consists of guided tutorials, journal clubs, and exposure to world-class researchers both on campus and from outside our institution. This ensures all fellows who graduate from this program have an ability to critically evaluate and engage emerging research findings and apply them to their clinical practice throughout their careers.

Research orientation program

Orientation to research methodology and options are focused into a common research block for all first-year fellows during the fall of the first year.

In addition to overviews of research options within the Division of Neonatology, Department of Pediatrics and Perelman School of Medicine at the University of Pennsylvania, fellows receive introductory seminars in biostatistics, epidemiology, study design, and developing a research hypothesis.

Ample time is given to fellows to participate in short research rotations with research mentors during the first year, which can help fellows determine their scholarly pursuits based on early experiences and evolving interests.

Scholarly project

All fellows propose and design (with the assistance of mentors) a comprehensive scholarly project. Beginning with project proposal and navigating oversight processes, data collection, and analysis, fellow projects culminate in a peer-reviewed publication. Almost all fellows present their work at regional and national conferences. As a result, our graduates are well positioned to compete for academic faculty positions, extramural funding, and pursue impactful academic careers.

Fellows enjoy the opportunity to pursue projects with the benefit of mentoring not only within the division of neonatology but also across the Perelman School of Medicine and the University of Pennsylvania. All fellows are guided in assembling a Scholarship Oversight Committee (SOC) comprised of intramural and extramural experts to mentor them through their scholarly projects  and provide guidance around other experiences that will contribute to their chosen scholarship focus.

The research curriculum can be supplemented with additional classes in biostatistics, epidemiology, molecular biology, etc. as determined by the fellow and research mentor(s)/ SOC. Fellows are encouraged to apply for both internal and external funding for research projects and can also apply to have their fellowship activities funded by T32 training grants.

Additional training and research opportunities

Advanced degree programs

Multiple advanced degree programs are available for fellows who successfully apply for funding. Each program consists of coursework and a thesis or practicum, requiring two years to complete. Further information is provided for each program below.

While there are additional graduate degree programs available at the University of Pennsylvania that some fellows have pursued, funding to support these degrees is more challenging. Fellows who have very strong motivation for pursuing this additional training have been supported, but this requires clear connection with future career goals and there are likely to be financial obligations borne by the fellow.

Certificate in Clinical Research

For trainees interested in clinical research, but who are not planning on pursuing a career as an independent physician-scientist, the Center for Clinical Epidemiology and Biostatistics offers a certificate program. This program consists of 5 courses, many of which are offered in short summer courses, and provides comprehensive training in epidemiology and biostatistics. Learn more.

Pediatric-Scientist Development Program

The Pediatric-Scientist Development Program (PSDP) is an NIH-sponsored program designed to provide research training relevant to specialty areas of pediatrics and to prepare entry-level faculty for research careers in academic pediatrics.

Physicians currently in a pediatric residency — who wish to train in basic, translational or clinical research with an established investigator/mentor — are encouraged to apply. Candidates seeking training in epidemiology/statistics, informatics, health services or health policy, are also encouraged to apply.

A commitment to an investigative academic career is essential and a strong background in research is required. The Neonatology Fellowship Training Program at CHOP has a strong history of fellows supported through this program. To learn more about this unique opportunity, contact program leadership.

Quality improvement training

The Accreditation Council for Graduate Medical Education (ACGME) incorporated quality improvement training into its Practice-Based Learning and Improvement (PBLI) and Systems-Based Practice (SBP) competencies.

Fellows are taught quality improvement (QI) and implementation science methods and participate in a QI project during fellowship. The QI project will be mentored by the Division of Neonatology’s QI Leadership Team.

Scheduled educational seminars

Clinical and research rotations for the Neonatal-Perinatal Medicine Fellowship Program are supplemented by a rich series of educational experiences. Every Wednesday afternoon, fellows are relieved of their clinical and research responsibilities to attend educational seminars. These seminars rotate on a 4-week schedule.

Week 1:

  1. Fellowship Meeting with Program Leadership
  2. Fellows Physiology Conference
  3. Neonatology Board Review or Review of Current Neonatology Literature

Week 2:

  1. Neonatology Radiology Rounds
  2. Journal Club

Week 3:

  1. Cardiology Case Discussion
  2. Neosurgery or Maternal Fetal Medicine Case Discussion
  3. Professionalism, Ethics and Communication seminar

Week 4:

  1. Point of Care Ultrasound training
  2. Simulation

The components of this schedule include:

Fellows Physiology Conference — This is a three-year curriculum of fetal and neonatal physiology and pathophysiology taught by neonatology and other subspecialty attendings from CHOP and the Perelman School of Medicine at the University of Pennsylvania (Penn). Topics include developmental anatomy, genetics, immunology and cardiorespiratory physiology. 

Cardiology Case Discussion — Cardiac intensivists participate in a monthly discussion of relevant cases in the NICU or the Cardiac Intensive Care Unit. Pathophysiology, cardiac anatomy, cardiac catheterization and echocardiogram results are reviewed and therapeutics discussed.

Neosurgery Case Discussion — Surgery and neonatology attendings participate in discussions of relevant cases in the NICU. Embryology, clinical presentation, and surgical and medical management are reviewed.

Maternal Fetal Medicine Case Discussion – Maternal Fetal Medicine, obstetric, and neonatology attendings participate in discussions of maternal fetal medicine physiology and pathophysiology and its impact on the fetus and neonate. Embryology, clinical presentation, and maternal and fetal management are reviewed.

Neonatal Radiology Rounds — Pediatric radiologists at CHOP participate in a monthly discussion of radiologic techniques and how they can be used to aid in the diagnosis and management of neonates and infants. Interesting cases are also reviewed.

Simulation — Fellows participate in multidisciplinary simulation education consisting of procedural training, neonatal and infant resuscitation in both the delivery room and NICU, and non-technical skills training (communication, teamwork, leadership, crisis resource management). Fellows will learn how to facilitate and debrief simulations, running mock codes for the pediatric residents.

Point of Care Ultrasound Training – First year fellows participate in both didactic and hands-on ultrasound training from the division’s ultrasound-trained faculty, learning to use POCUS for procedural guidance and diagnostics. Senior fellows have the option to continue POCUS training through one-on-one sessions with augmented reality ultrasound simulators, hands-on practice with patients, and through individual feedback from faculty.

Neonatology Board Review — Every other month fellows participate in neonatology board review sessions that focus on high-yield reviews of topics covered by the American Board of Pediatrics subspecialty examination in Neonatal-Perinatal Medicine. An audience response system is employed to engage the fellows in test-taking techniques.

Review of current neonatology literature — Every other month fellows divide up the current neonatology literature and present a short summary of newly published reports and findings. In this way, the fellows collaborate with one another to keep the entire group up-to-date on the latest research in neonatology.

Journal Club — The Journal Club is a monthly seminar that supports the acquisition of biostatistical and epidemiologic tools necessary to complete a research project, and promotes an evidence-based approach to clinical care. Led by faculty with advanced training in clinical research methodology, this seminar provides didactic and practical experience in biostatistics, clinical epidemiology and clinical study design. To reinforce concepts, the group reviews a neonatology-focused paper in clinical research each session.

Professionalism, Ethics, Communication, Etc (PECx)  — Fellows receive instruction in topics relating to professionalism and bioethics. Fellows also participate in communication training using evidence-based approaches and standardized patients to enhance communication skills in areas such as perinatal counseling, giving difficult news and medical error disclosure. This training is partnered with a variety of non-clinical topics in the practice of medicine. The topics covered in this “Etc” series have included:

  • Life as a N/IICU director
  • Medicolegal topics for neonatology attendings
  • NICU care, billing and collections: How are they connected?
  • So you want to be a neonatology program director?
  • Work-life integration
  • Teaching in a clinical setting

Career development curriculum

Because teaching and written and oral communication are integral parts of a career in academic neonatology, we require fellows to participate in seminars designed to foster these skills that are offered by the Offices of Faculty and Professional Development at CHOP and the Perelman School of Medicine at the University of Pennsylvania.

Each fellow is encouraged to take at least one seminar focused on writing a grant, clinical manuscript, or basic science manuscript. Other seminars are chosen based on each individual fellow's strengths, weaknesses and professional development needs, and can include:

  • Providing feedback in a clinical setting
  • Conducting an effective Q & A session
  • Developing effective presentations
  • Abstract preparation
  • Effective poster and platform presentations
  • Introduction to advanced PowerPoint

Divisional and departmental conferences

Clinical conferences at CHOP and HUP

Fellow-led clinical conferences are held weekly and alternate between HUP and CHOP. Each site holds a Morbidity and Mortality Conference monthly.

Topics at HUP have an emphasis on maternal-fetal medicine and routine neonatology patients. Topics at CHOP relate to the management of patients in a quaternary care NICU and often include surgical care, ECMO therapy, and transport issues.

Neonatology Research Seminar Series

Neonatology Research Seminar is a weekly seminar serving as an official forum for fellows, neonatal faculty, and visiting lecturers to present their research. Each fellow will present the final results of his/her research project to the Division of Neonatology during their final year of training.

Department of Pediatrics Fellows’ Core Curriculum

The Department of Pediatrics currently has over 50 subspecialty fellowship programs, over 200 fellow trainees and a plethora of talented educators. Despite the diversity of subspecialties represented, there are many common educational requirements across our various training programs. The CHOP Fellow Core Curriculum has two main goals; to provide educational content required for all pediatric subspecialty fellows in an engaging, innovative format and to build a sense of community across the fellowship training programs at CHOP. 

The Fellow Core Curriculum will provide pediatric fellows additional training opportunities in several ways:

Content specific sessions focused on a single topic area.  For example, quality improvement curriculum was identified as a need by program directors.  An introduction to QI workshop, advanced QI skills sessions, and a patient safety session for fellows are offered throughout the year.

“Developmentally” focused sessions will cover a variety of topics that are relevant to fellows during particular stages of their training including:

  • Quality Improvement Methodology
  • Half day retreats by year of training
  • Orientation First Year: Time management, Fatigue mitigation, Introduction to CHOP and Penn, Wellbeing, Tips and Tricks to Success as a Fellow, Diversity and Inclusion
  • Spring First Year: Grant funding, Mentee-Mentor Relationship, Research Design, Advanced library skills
  • Second Year: Leadership, Communication skills, Presentation, Health Care Disparities, Teaching skills
  • Fall Third Year – Success in the Job Search: Job search overview, interview skills, CV and Cover letter workshop,
  • Spring Third Year – Transition to Attending: Leadership skills, Work-life integration, Time management, Billing, Life-long learning, Personal Finance

We will continue to build a Fellow Core Curriculum program that is varied in both content and structure to engage as many fellows as possible across our training programs over the next several years. Additionally, we’ve constructed a new online library of Fellow Core Curriculum content for our fellows on the updated internal GME website.

Pediatric Grand Rounds

Departmental Ground Rounds occur every Wednesday morning.

Clinical consensus

Four to five times a year, a group of fellows and faculty members present a controversial topic in patient management. Participation of nursing, front-line care providers, and ancillary staff is encouraged. The group works to build a consensus statement through iterative review for adoption as a practice guideline for the division. All fellows are required to participate in at least one clinical consensus during fellowship.
