Evolving Extremely Preterm Population Care Models: Implications for Fellowship Training, Workforce Readiness, and Educational Equity.
This study of 97 U.S. Neonatal-Perinatal Medicine fellowship programs reveals that while fellows remain integral to extremely preterm patient care, evolving team structures dominated by advanced practice providers necessitate clearer role definitions and graduated autonomy to balance educational goals with clinical demands.

Imagine the most delicate, tiny humans on Earth: babies born so early that they are smaller than a loaf of bread and need a high-tech life-support system just to breathe. These are the "extremely preterm" infants. Caring for them is like trying to pilot a spaceship while it's still being built; every decision matters, and the margin for error is microscopic. To handle this, hospitals have special units called Neonatal Intensive Care Units (NICUs), staffed by a dream team of experts. But there's a twist: the doctors who will eventually lead these teams are still in training. They are called "fellows," and they are like the senior apprentices in a high-stakes culinary school, learning to cook the most complex, fragile meals imaginable. The big question isn't just if these trainees get to cook, but how they fit into a kitchen that is already full of other highly skilled chefs, like nurse practitioners and physician assistants, who are there to do the heavy lifting every single day.
This paper is a massive check-in with the entire United States to see how these training kitchens are organized. The researchers surveyed nearly every Neonatal-Perinatal Medicine fellowship program in the country—97 of them, which is about 91% of the total—to ask a simple but tricky question: How do you balance teaching the future doctors with actually taking care of the tiniest, most vulnerable babies? They wanted to know who is doing the work, who is watching, and where the bumps in the road are.
Here is what they found. First, almost every single program is taking care of these tiny patients, and more than half (56%) have set up special, dedicated teams just for them. It's like having a specific "Tiny Baby Wing" in the hospital. But who is actually at the bedside? Surprisingly, the most common frontline workers are Advanced Practice Providers (APPs)—highly trained nurse practitioners and physician assistants—who handle about 85% of the direct care. Fellows are right behind them, doing frontline work 60% of the time, followed by residents (43%) and hospitalists (10%).
The role of the fellow is a bit like a video game where you start on "Easy Mode" and work your way up to "Hard Mode." In many programs, fellows start as the main hands-on doctors, then slowly shift into a "supervisor" role as they get smarter and more skilled, eventually acting like a "pre-doctor" who guides the whole team. They do everything from counseling parents before the baby is even born, to rushing into the delivery room to help the baby take its first breath, to performing delicate procedures.
However, the paper suggests that this setup isn't always smooth sailing. The authors found several "traffic jams" in the training process. One major issue is confusion over who is the captain of the ship. Sometimes, the roles aren't clear, leading to awkward moments where the fellow isn't sure if they should be making a decision or just watching. There is also a "procedural tug-of-war," where fellows and APPs might be competing for the chance to perform specific, hands-on tasks, like inserting a tube or managing the airway. If the fellow doesn't get enough practice because the APP is doing it all, the fellow might graduate without the necessary skills.
Another hurdle is communication. If the APPs or nurses are making all the decisions before the fellow walks into the room, the fellow misses out on the chance to learn how to solve problems. The paper notes that some fellows feel left out of the loop, which can make them feel less valuable and slow down their growth as leaders.
The researchers also pointed out a changing landscape: because there are fewer residents (the doctors-in-training who come before fellows) spending time in the NICU, many fellows are arriving at their training with less experience than before. This means the fellow programs might need to work harder to give these trainees enough "frontline time" to get comfortable with the tiny babies.
In short, the paper suggests that while fellows are still a crucial part of the team, the current way many hospitals are organized might be making it harder for them to learn everything they need to know. The authors propose that if programs create clearer rules about who does what, make sure everyone talks to each other effectively, and give fellows a structured path to take on more responsibility as they learn, everyone wins. The babies get safer care, and the future doctors graduate ready to lead their own teams. It's a call to tidy up the training kitchen so the next generation of neonatal heroes can step up to the stove with confidence.
