Who is missing out on GP enrolment? Determinants of GP non-enrolment in the Netherlands and its impact on healthcare utilization and health
This study of Dutch residents from 2017–2023 reveals that individuals with non-Dutch origins, low incomes, and specific demographic characteristics are disproportionately unenrolled with general practitioners, a status associated with lower healthcare utilization but a significantly increased risk of mortality.

Imagine the Dutch healthcare system as a massive, well-organized library. In this library, the General Practitioner (GP) is the friendly librarian at the front desk. You don't need a ticket to walk in, and they know your reading history. They are the "gatekeepers" who can hand you a special pass to see the rare books in the back (hospitals) or help you manage a long-term reading project (chronic diseases).
However, to get that pass, you have to officially enroll with a specific librarian. You aren't forced to do it, but the library strongly suggests it.
This study is like a detective report trying to answer two big questions: Who is walking around this library without a librarian, and what happens to them?
1. Who is "Missing" from the Library?
The researchers looked at millions of records to find the people who didn't sign up with a librarian between 2017 and 2023. They found that the number of unenrolled people is growing (doubling from about 0.9% to nearly 2% of the population).
Who is most likely to be without a librarian?
- The Newcomers: People who just moved to the Netherlands (especially from other European countries) are the most likely to be lost in the stacks. It's like arriving in a new city and not knowing which bus stop to take.
- The Movers: People who just moved their house within the country often forget to update their address with the library.
- The "Solo" Readers: Men, particularly those aged 20 to 49, and people living alone are less likely to sign up.
- The Budget-Conscious: People with lower incomes and those living in neighborhoods with lots of rental apartments (rather than owned homes) face higher odds of being unenrolled.
- The City Dwellers: People in very crowded, urban areas are more likely to be without a GP than those in quiet, rural villages.
Interestingly, the study found that people with low education or those receiving government benefits were not necessarily more likely to be unenrolled. The barriers seem to be more about being new, moving, or being a young man in the city.
2. What Happens When You Don't Have a Librarian?
The researchers compared the "unenrolled" group to the "enrolled" group to see how their health and spending differed.
The Spending Paradox
- Less Spending: People without a GP spent significantly less money on healthcare (about 38% less). They visited the hospital less, bought fewer medicines, and used fewer services.
- The Catch: This wasn't because they were healthier. It was because the "gate" to the healthcare system was locked. Without a librarian to give them a referral, they couldn't easily get to the specialists or the hospital. It's like trying to buy a rare book but not having the key to the back room; you just end up buying nothing.
The Health Reality
- Higher Risk of Death: Despite spending less money, the unenrolled group had a sharply higher risk of dying in the following year. Their risk of death was more than double that of the enrolled group.
- Why? The causes of death were telling. While enrolled people mostly died from things like cancer (which are often detected early by GPs), the unenrolled group died more often from:
- Mental health issues (like dementia or addiction).
- Infections (which a GP could have treated early).
- External causes (accidents or violence).
The study suggests that without a GP to act as a guide and a gatekeeper, these individuals hit a wall. They can't get the care they need, leading to worse outcomes and, tragically, higher mortality.
The Bottom Line
This study reveals a hidden inequality in the Dutch healthcare system. Even though everyone has health insurance, a specific group of people—recent migrants, young men, the poor, and city dwellers—are falling through the cracks. They aren't getting the "librarian" they need to navigate the system.
The result is a dangerous cycle: they use less healthcare because they can't get in, and because they can't get in, their health suffers, leading to a much higher risk of death. The authors suggest that fixing this requires understanding these barriers so that targeted help can be given to get these "lost" people enrolled with a GP.
