Johns Hopkins All Children's Hospital

Neonatal-Perinatal Medicine Fellowship Program

Johns Hopkins All Children’s Hospital’s Neonatal-Perinatal (NPM) Fellowship Program, a three-year, ACGME accredited program (National Resident Matching Program Fall match), offers a dynamic learning experience, within an innovative, collaborative and learner-centric environment.


Innovative Learning Environment

The Mission of the NPM fellowship program is to train the next generation of leaders in Neonatal-Perinatal Medicine, within an innovative, collaborative, personalized and learner-centric environment. Fellows will develop superior skills in delivering family-engaged patient care through a systems-based model, advocating for safety, quality and value-based care, and in advancing scientific research and investigation.

A dedicated simulation laboratory within the NICU is equipped with the most advanced technology available for simulation-based learning. Dedicated and specially trained simulation laboratory staff assist core teaching faculty with a wide spectrum of learning scenarios.

A personalized academic structure will allow the fellow to advance individual learning objectives and develop expertise in a specialized area of interest, facilitated by the institute’s patient-centered, cohort-based continuum of patient care model, beginning at delivery in Bayfront’s Baby Place, continuing through the hospital course in the 97-bed Level IV NICU, and extending through the Neonatal Follow-Up Clinic and Neonatal Medical Home.

Research and Investigation

The Johns Hopkins All Children’s Maternal, Fetal and Neonatal Institute and the NPM fellowship program provide the fellow a range of opportunities to pursue clinical, integrative basic science and translational research, as well as quality improvement. The program benefits from research collaboration with the Johns Hopkins Medicine campus in Baltimore and the multicenter MFNI-wide research patient population. The institute has committed to a state of the art “omics” approach to investigation, with emphasis on microbiota, microbiome, biomarkers and links to clinical outcomes.

The Johns Hopkins All Children’s Institute for Clinical and Translational Research includes the Research and Grant Administration Core, Study Design and Analysis Core, the Pediatric Biorepository, the Research Operations Core, the Database Design and Data Management Core, the Investigational Drug-Services Core, the Regulatory Affairs and Quality Assurance Core, and the Investigational New Drug/Investigational Device Exemption Core.

Maternal, Fetal & Neonatal Institute (MFNI)

The Johns Hopkins All Children’s Maternal, Fetal & Neonatal Institute seeks to improve outcomes for newborns through collaborative approaches to value-based care, beginning with the high-risk expectant mother, continuing through delivery and neonatal intensive care unit (NICU) admission, and extending beyond discharge through patient-centered cohort-based neonatal follow-up.

The institute works closely with Bayfront’s Baby Place, located within Johns Hopkins All Children’s Hospital. Baby Place averages 4,200 deliveries per year and is a state-approved Level III Regional Perinatal Intensive Care Center. The maternal-fetal specialists are Johns Hopkins All Children’s faculty, and their referrals originate from a large geographical area extending beyond the west coast of Florida to a growing number of national and international locations. Complex congenital anomalies and maternal complications are managed by a multidisciplinary team, including maternal-fetal medicine specialists, neonatologists, geneticists, cardiologists, surgeons and other diverse specialists, working together to offer a continuum of care that meets the needs of patients and families in a patient-centered Neonatal Medical Home model.

The institute’s mission is to disseminate clinical excellence, innovate through research and train the next generation of physicians to continue improving the short-and long-term health outcomes and needs of medically complex newborns. The MFNI provides neonatal and high-risk obstetrical clinical care at a number of community hospitals within the west coast of Florida.

The institute collaborates in clinical care, advocacy and research with Johns Hopkins All Children’s Hospital’s Heart Institute, Institute for Brain Protection Sciences and Cancer & Blood Disorders Institute, along with a full-spectrum of pediatric medicine subspecialty divisions.
