Blended E-Learning and Virtual Reality Refresher for Postgraduate Procedural Training: a Mixed-Methods Feasibility Study

Imagine the medical world as a high-stakes video game where players must perform life-saving moves, like inserting a tube into a chest to help someone breathe or threading a tiny wire into a major vein to deliver medicine. These aren't just simple button presses; they are complex, physical skills that require a steady hand, deep knowledge, and the ability to stay calm under pressure. In the real world, doctors-in-training usually learn these moves by practicing on fake patients (manikins) in a classroom. But here's the catch: just like a musician who stops practicing their instrument, doctors can forget these tricky skills if they don't use them often. The problem is that finding a teacher, a fake patient, and a room to practice in is like trying to schedule a meeting with three different celebrities at the same time—it's hard to do, so practice sessions often get cancelled or skipped.

To solve this, scientists are exploring a new kind of training mix, called "blended learning." Think of it like a video game that combines a strategy guide (reading and watching videos on a computer) with a virtual reality (VR) headset that lets you actually "play" the procedure in a digital world. This paper asks a simple but important question: Can we use this mix of online learning and VR to help doctors-in-training refresh their skills without needing a teacher standing over their shoulder every single time? It's like asking if a pilot can keep their flying skills sharp by using a flight simulator at home, rather than only practicing in a real cockpit with an instructor.

The Experiment: A Digital Do-Over

In this study, researchers at McGill University in Canada set up a digital training camp for postgraduate medical learners—basically, doctors who have already finished medical school and are now specializing in fields like surgery, anesthesia, or family medicine. They wanted to see if a "booster shot" of training could work using a two-step process. First, the doctors read interactive e-learning modules on their computers, which were like digital textbooks with videos and quizzes about chest tube insertion and central venous catheterization (a fancy name for putting a line in a big vein). Second, they put on a VR headset (Meta Quest 3) and practiced the procedures in a simulated operating room, getting instant feedback from the computer on how well they did.

The study wasn't a massive trial; it was a "feasibility study," which is a fancy way of saying, "Let's see if this idea actually works in the real world before we build a whole factory for it." They invited 13 doctors to try it out. In the end, 7 of them completed the full journey, choosing to practice either the chest tube procedure, the vein line procedure, or both.

What They Found: The Good, The Bad, and The Scheduling Struggle

The results were a mix of "awesome" and "a bit tricky."

First, the doctors loved the idea. They rated the learning materials as very clear and well-organized, giving them a top score of 5 out of 5. They felt the VR practice was practical and helpful. In fact, the overall satisfaction was sky-high, with a median score of 5 out of 5. It seems that for these busy medical learners, having a flexible, self-paced way to review their skills was a hit.

When it came to what they actually learned, the results depended on which procedure they practiced. For the chest tube insertion, the doctors' knowledge jumped significantly. Before the training, they got about 60% of the quiz questions right. After the e-learning and VR practice, that number soared to 93%. This suggests that for skills they hadn't used in a while, this digital refresher was a powerful tool to get their brains back in the game.

However, for the central venous catheterization (the vein line), the story was different. The doctors started with very high knowledge scores (around 90%) and ended with even higher ones (95%), but the change wasn't statistically significant. The researchers suspect this is because these doctors were already experts in this specific area; they were so good to begin with that there was almost no room to get better. It's like trying to teach a professional basketball player how to shoot a free throw when they are already hitting 90% of them; there's a "ceiling" where it's hard to show improvement because they were already near the top.

Confidence levels also went up slightly (from a median of 4 to 5 on a 5-point scale), but the change wasn't big enough to be considered a guaranteed statistical win. The authors suggest that confidence might need more than just one quick digital session to truly solidify.

The Hurdle: Finding Time in the Calendar

While the learning part worked well, the logistics had a snag. The biggest complaint from the participants was scheduling. The VR sessions had to happen during regular business hours at the simulation center. For doctors who are already working long shifts in hospitals, finding a free hour during the day is like finding a needle in a haystack. Several participants noted that they struggled to book a time that didn't clash with their clinical duties. One even suggested that if the sessions were available after hours, it would be much easier to fit in. This tells us that while the technology works, the schedule needs to be more flexible to fit into the chaotic lives of real doctors.

The Bottom Line

This study suggests that blending e-learning with immersive VR is a promising way to help doctors keep their procedural skills sharp. It works well for refreshing knowledge, especially for skills that aren't used every day, and the doctors who tried it really liked it. However, the paper doesn't claim this is a perfect, solved solution yet. The sample size was small, and the study only looked at what the doctors knew and felt about their skills, not whether they could actually perform the procedure perfectly on a real patient later.

The authors conclude that this approach is feasible and accepted by trainees, but they warn that we need bigger studies to see if this digital practice actually translates to better performance in the real operating room. They also highlight that for this to truly work in the future, the system needs to be more flexible with time, allowing doctors to practice when they are actually free, not just when the simulation center is open. It's a solid first step toward a future where doctors can keep their skills sharp with a quick VR session, but the journey to making it a standard part of medical training is just beginning.
