Characterizing Gaps in Delirium Prevention: A Multicentre Cross-Sectional Analysis of Nurse-Reported Screening, Barriers, and ICU--Ward Practice Differences
This multicentre cross-sectional study of 234 nurses in Türkiye reveals critical gaps in routine delirium-risk assessment and monitoring while highlighting distinct, setting-specific implementation patterns where ICU nurses excel in pain management and transfer avoidance, whereas ward nurses more frequently report environmental, family, and restraint-related preventive practices.

Imagine the human brain as a high-performance computer that usually runs on a steady operating system. Sometimes, however, a sudden storm hits the server room, causing the screen to flicker, the cursor to jump, and the user to forget how to type. In the medical world, this chaotic state is called delirium. It's not just "being confused"; it's a sudden, acute disturbance where a person loses their grip on attention, awareness, and clear thinking. It often happens when people are sick in the hospital, especially if they are in pain, can't sleep, or are surrounded by too much noise.
The good news is that we know how to keep this "computer" running smoothly. Doctors and nurses have a playbook of non-medicine tricks to prevent delirium: making sure the patient gets enough sleep, turning down the noise, letting family visit, helping them move around, and keeping them oriented to the time and place. But just because you have a playbook doesn't mean everyone is playing the game the same way. The big question researchers ask is: Are hospitals actually using these tricks? And does the way they play change depending on whether the patient is in the super-high-tech Intensive Care Unit (ICU) or a regular hospital ward? This is where our story begins.
The Great Hospital Detective Hunt
A team of researchers decided to play detective in five big training hospitals in Istanbul, Turkey. They didn't look at patient medical charts; instead, they asked 234 nurses to spill the beans on how they actually handle delirium prevention. They wanted to know: Do you check for delirium risk when a patient walks in? Do you keep an eye on the high-risk ones? And what stops you from doing the things you know you should?
The results were a bit like finding out that while everyone has the same instruction manual, nobody is actually reading the first page.
The Missing Checklist
Here is the shocking part: Not a single nurse (0 out of 234) reported that they routinely check for delirium risk for every new patient walking through the door. It's as if a security guard at a concert never checks the tickets of the people entering, even though the rules say they should. When the researchers asked why, the nurses pointed to three main culprits:
- No easy tool: They didn't have a quick, simple checklist to use.
- Too busy: The workload was so heavy there was no time.
- No bossy orders: The hospital didn't strictly expect them to do it.
Even for the patients who were already known to be at high risk, only 44 nurses (about 19%) said they monitored them regularly. And here's the kicker: those who did monitor them weren't using fancy, scientific tools. They were just watching to see if the patient could follow a command or if they were acting agitated. It was a "gut feeling" approach rather than a structured one.
The ICU vs. The Ward: A Tale of Two Worlds
The study then split the nurses into two groups: those working in the Intensive Care Unit (ICU) and those in the general wards. They compared how often each group performed 18 different prevention tasks, like giving pain relief, reducing noise, or letting family visit.
The results showed that the two environments have very different "superpowers" and different "weaknesses." It's not that one group is better; they just have different jobs.
Where the ICU Nurses Shined:
The ICU nurses were the champions of pain relief and keeping patients in one place. They reported doing these things more often than ward nurses.
- The Analogy: Think of the ICU as a high-security vault. Once a patient is inside, they are rarely moved, and the staff is hyper-focused on keeping them comfortable and stable. The nurses there are experts at "locking down" the patient's environment to prevent unnecessary changes.
Where the Ward Nurses Shined:
The general ward nurses, however, were the masters of the environment and the human touch. They reported doing the following much more often than ICU nurses:
Helping patients get good sleep.
Reducing noise (turning down the volume).
Letting family and friends visit regularly.
Making sure the lighting was adequate.
Avoiding unnecessary catheters (tubes).
Avoiding physical restraints (tying patients down).
The Analogy: Think of the general ward as a bustling community center. It's easier to bring in family, keep the lights on a warm setting, and let people walk around. The ICU, by contrast, is a sterile, noisy, high-tech zone where family visits might be restricted, lights are often harsh, and patients are tethered to machines, making it harder to create a "sleepy, calm" atmosphere.
The Numbers Don't Lie
The researchers ran the numbers through a special statistical filter to make sure these differences weren't just luck. They found that 8 out of 14 of these comparisons were statistically significant.
- ICU nurses were 2.18 times more likely to report frequent pain relief.
- ICU nurses were 2.29 times more likely to avoid moving patients to different rooms.
- Conversely, ward nurses were much more likely to report doing the "sleep and family" stuff. For example, the odds of ICU nurses reporting they avoided physical restraints were much lower (0.28 times) than ward nurses, meaning restraints were used more often in the ICU.
What This Means (And What It Doesn't)
The study suggests that hospitals aren't failing because nurses don't know what to do; they are failing because the system makes it hard. The barriers—like lack of time, lack of tools, and lack of clear expectations—are the same in both places.
The paper doesn't say one unit is "better" than the other. Instead, it suggests that the ICU is great at pain management and stability but needs to work harder on sleep, noise, and family connection. The wards are great at creating a human-friendly environment but might need to focus more on pain management and keeping patients from being shuffled around unnecessarily.
The Bottom Line
This research is a snapshot in time (from 2018–2019) of what nurses say they do. It suggests that to stop delirium, hospitals need to stop treating all wards the same. They need to give ICU nurses the tools to create a quieter, sleep-friendly zone, and give ward nurses the support to manage pain and keep patients put. It's not about blaming the nurses; it's about fixing the game board so everyone can play their best.
