Re-shaping professional boundaries to scale-up HIV pre-exposure prophylaxis (PrEP) services: collaborative care and power dynamics in Belgium
This study reveals that scaling up HIV pre-exposure prophylaxis (PrEP) services in Belgium beyond specialized clinics is hindered not just by operational challenges, but primarily by structural power dynamics, reimbursement regulations, and professional jurisdictional boundaries that reinforce specialist dominance and limit general practitioner involvement.

Imagine the healthcare system as a massive, bustling city. In this city, different neighborhoods have their own rules, budgets, and local leaders. Some neighborhoods are specialized hubs, like a high-tech medical district, while others are the everyday community clinics where most people go for check-ups. Now, imagine a new, life-saving tool arrives in this city: a daily pill that stops a virus from taking hold before it ever starts. This is PrEP (pre-exposure prophylaxis), a powerful shield against HIV. The big question for the city planners isn't just "Do we have enough pills?" but "Who gets to hand them out?"
For a long time, handing out these special shields was like a VIP club event, managed only by the experts in the high-tech medical district. But to save more lives, the city needs to open up the distribution to the everyday community clinics too. This is where things get tricky. It's not just about training doctors; it's about power. Think of "competitive power" as a group of experts guarding their castle, saying, "Only we know how to do this safely," while "collaborative power" is the art of neighbors working together, sharing keys, and trusting each other to keep the whole city safe. This paper dives into the story of how these different groups in Belgium tried to figure out who should hold the keys to the PrEP castle, and why it's harder than just saying, "Let's all help."
The Battle for the Keys: Who Gets to Hand Out the HIV Shield?
In Belgium, the story of PrEP is a bit like a high-stakes game of musical chairs, but instead of chairs, everyone is fighting over who gets to prescribe the HIV prevention pill. The researchers, a team of curious detectives from universities in South Africa, the UK, and Belgium, wanted to understand why it's so hard to spread this life-saving service from the specialized HIV clinics (the "VIP castles") to the regular family doctors (the "neighborhood shops").
To solve the mystery, they didn't just look at medical charts. They went on a listening tour. They chatted with 36 people working inside the specialized HIV clinics—including doctors, nurses, and psychologists—and held 16 online group discussions with family doctors (GPs). They also talked to two representatives from community groups that help the most vulnerable people. They even read the official rulebooks that govern how the system is paid for. Their goal was to see how "power" works when different groups try to work together.
The Rules of the Game: The Castle Keepers
The researchers found that the official rules act like a giant gatekeeper. In Belgium, the government's funding rules say that only the specialists in the HIV clinics can officially start a patient on PrEP and handle the first few check-ups. It's like the rulebook says, "Only the knights in the castle can give out the magic swords."
Because the specialists get paid to run the clinics and the community doctors don't get paid to do this specific job, the specialists naturally feel like they own the territory. One specialist admitted it plainly: "Ideally, this should be done in the neighborhood, but the bottom line is, we earn less money if we send all these patients to their GP." This isn't just about being stubborn; it's about the system being set up to keep the power in one place. The rules create a "competitive power" dynamic where the specialists protect their territory, not because they are mean, but because the system tells them they are the only ones allowed to do it.
The Neighborhood Shopkeepers: "We Want to Help, But..."
On the other side of the fence, the family doctors (GPs) are saying, "We want to help, but we feel locked out." They feel like the system has deliberately bypassed them. One GP explained, "We are deliberately bypassed by the system... so naturally we lose contact with it."
The doctors feel they lack the experience because they haven't been allowed to practice. They worry they aren't "cool" enough or knowledgeable enough about the specific needs of the people who need PrEP, like the LGBTQ+ community. But the specialists worry too! They think, "If a GP only sees one person a month, how can they know the complex stuff about drugs, other infections, and mental health?" It's a standoff where both sides think the other isn't ready, but the rules prevent them from ever trying to prove they are.
The Helpers in the Middle: Nurses and Community Groups
While the doctors and specialists argue over who holds the keys, the nurses inside the clinics are actually doing a lot of the heavy lifting. The researchers found that inside the castle, there is a lot of "collaborative power." The doctors and nurses work together like a well-oiled machine. The nurses handle the follow-ups, the counseling, and the emotional support, while the doctors keep the final say on the prescription. It works well because they are in the same building, trust each other, and have a shared goal.
Then there are the community groups (CBOs). These are the friendly neighbors who know the people on the street. They act as bridges, helping vulnerable people get to the clinic. They even have informal deals with the doctors to help people who don't have insurance or legal status. But even here, the power dynamic is tricky. The community groups have to navigate the rules, sometimes bending them just enough to get help to people who need it, while the specialists keep a watchful eye to make sure everything stays "legal."
The Big Takeaway: It's Not Just About Training
So, what did the researchers learn? They found that the problem isn't that family doctors are lazy or that specialists are greedy. The problem is the system.
The paper suggests that you can't just train more doctors and expect the system to change. If the rules say "Only the castle can do this," then the castle will keep the keys, and the neighborhood shops will stay empty. The researchers argue that to really scale up PrEP and help more people, the city planners need to change the rules of the game. They need to:
- Rewrite the rulebook: Change the funding so that family doctors are actually paid and allowed to prescribe PrEP.
- Build better bridges: Create official ways for the castle and the neighborhood shops to talk to each other, rather than relying on random phone calls or personal friendships.
- Trust the team: Recognize that nurses and community groups are essential parts of the team, not just helpers.
The study doesn't say the current system is broken beyond repair, but it does suggest that without changing the deep-down rules about who gets paid and who has authority, the "VIP club" will stay closed, and the people who need the shield the most might never get it. It's a reminder that in healthcare, just like in a city, you can't fix traffic jams just by telling drivers to drive better; sometimes, you have to change the roads.
