Cost-effectiveness of seizure detection devices for high-risk night-time epileptic seizures: study protocol of a pre-post clinical trial in Dutch long term care facilities (KANS-project)
The KANS-project is a pre-post clinical trial protocol designed to evaluate the clinical effectiveness, user experience, and cost-effectiveness of NightWatch and Epi-Care Free seizure detection devices for high-risk night-time epileptic seizures among 44 residents in Dutch long-term care facilities over a 12-month period.

Imagine your brain is a bustling city where billions of tiny messengers run around delivering notes. Usually, they follow the rules, but sometimes, a whole neighborhood gets a sudden, chaotic power surge. This is an epileptic seizure. For most people, these surges are rare or manageable, but for some, they happen often and can be dangerous, especially when they occur while sleeping. The biggest fear in these quiet hours is a rare but tragic event called SUDEP (Sudden Unexpected Death in Epilepsy), which happens more often when no one is awake to notice the trouble.
To keep people safe, we have "night watch" systems. Right now, many care homes use simple audio monitors that listen for loud noises or bed sensors that feel for shaking. But here's the catch: not all seizures make noise, and some don't shake the bed hard enough to trigger an alarm. It's like trying to hear a whisper in a storm or feeling a cat walk across a mattress. Because of this, scientists are testing high-tech "smart watches" and wristbands designed to spot these invisible surges. The big question isn't just "do they work?" but "are they worth the money?" If these gadgets save lives and prevent injuries, does the cost make sense for the healthcare system? This is the puzzle a new study called the KANS-project is trying to solve.
The Night Watch Mission: A Study in Dutch Care Homes
This paper is a study protocol, which is basically a detailed recipe for a scientific experiment that hasn't been cooked yet. The authors, a team from Maastricht University and other Dutch medical centers, are planning a "pre-post" clinical trial. Think of it like a time-travel experiment where 44 adults living in long-term care facilities (mostly those with intellectual disabilities) will act as their own time travelers.
First, the team will observe these participants for three months using the "old way" of doing things: standard care with no special seizure-detecting gadgets. This is the "baseline." Then, for the next 12 months, each person will wear one of two high-tech devices: either a NightWatch or an Epi-Care Free. These aren't just fancy fitness trackers; they are medical devices approved to detect specific types of seizures, particularly the big, shaking ones known as generalized tonic-clonic seizures.
The Detective Work: How They'll Measure Success
To see if the gadgets are actually helping, the researchers are playing a high-stakes game of "spot the difference." For the first six months of the study (the last three months of the old way and the first three months of the new way), they will set up video cameras in the participants' rooms. These cameras will watch the beds all night, but with a privacy cover that caregivers can pull down if they need to.
The video footage will be the ultimate referee. The team will look at every seizure caught on tape and ask: "Did a healthcare worker come to help within five minutes?"
- Correct Visit: The worker arrived in time.
- Missed Visit: The worker didn't show up, meaning the seizure went unnoticed.
By comparing the "missed" rates from the old days to the "missed" rates with the new gadgets, they hope to prove that the devices wake up the staff faster. They will also count how many injuries or complications happen during seizures and ask the staff and patients how they feel about wearing and using the devices.
The Money Question: Is It Worth the Price Tag?
The study isn't just about safety; it's about the wallet, too. The researchers will perform a "cost-effectiveness analysis." Imagine a scale. On one side, they put the cost of buying and using these devices for a whole year. On the other side, they put the value of the benefits: fewer missed seizures, fewer injuries, and better quality of life for the patients.
They will use a special questionnaire called the PWE-ID-SUS to track exactly how much time and money is spent on care. They want to know if the extra cost of the gadgets is balanced out by saving money on hospital visits or preventing serious accidents. In the Netherlands, they have a specific "price tag" they are willing to pay for a year of healthy life (called a QALY), and they will see if these devices fit within that budget.
Why This Matters (And What It's Not)
The authors are very clear about what they are not doing. They are not trying to prove that one gadget is better than the other; they are just testing if any good gadget is better than having no gadget at all. They also aren't using the "gold standard" of brain-scanning machines (video-EEG) because it's too expensive and impractical to run for a whole year in a home setting. Instead, they are relying on video and caregiver reports, which is a realistic test for how these devices would work in the real world.
The team expects to find that these devices will catch more seizures and wake up the staff faster, but they are careful to say this is a plan to find out, not a finished result. They chose a "pre-post" design (testing the same people before and after) instead of a random control group because they felt it would be unethical to keep some people without these safety tools if they chose to join the study.
By the end of this year-long adventure, the KANS-project hopes to give Dutch health insurers a clear answer: Are these seizure-detecting devices a smart investment that saves lives and money, or are they just a nice-to-have gadget? If the numbers add up, it could mean that more people in care homes get to sleep safely, knowing that if the city of their brain has a power surge, someone will be there to help.
