Knowledge, Attitude, and Practice Regarding Biomedical Waste Management Among Healthcare Workers in Aden, Yemen: A Multilevel Cross-Sectional Study
This multilevel cross-sectional study of 502 healthcare workers in Aden, Yemen, reveals a significant gap between favorable attitudes and poor biomedical waste management practices, identifying previous training and facility-level support as critical predictors of safe practices in conflict-affected settings.

Imagine a hospital as a busy kitchen. In a kitchen, you have raw meat, dirty dishes, and sharp knives. If you mix the raw chicken with the clean plates, or leave the knives lying around, someone gets hurt or sick. In a hospital, this "mess" is called Biomedical Waste (like used needles, infected bandages, or old medicine).
This study is like a big inspection of 15 different kitchens (hospitals and clinics) in Aden, Yemen, a city that has been through a lot of trouble due to war. The researchers wanted to know: Do the people working there know how to clean up safely, do they care about it, and are they actually doing it?
Here is the breakdown of what they found, using simple comparisons:
1. The Big Problem: Knowing vs. Doing
The researchers asked the workers three types of questions:
- Knowledge: "Do you know the rules?" (Like knowing that you must wash your hands).
- Attitude: "Do you think the rules matter?" (Like believing that washing hands prevents sickness).
- Practice: "Are you actually doing it?" (Like actually washing your hands).
The Result:
- Knowledge: Most workers knew the rules (55% were "good" at this). It was like a student who studied hard for the test.
- Attitude: Most workers cared deeply about safety (71% had "favorable" attitudes). They wanted to be safe.
- Practice: But when it came to actually doing the work, only 48% were doing a "good" job.
The Analogy: Imagine a driver who knows the traffic laws perfectly and loves driving safely, but still runs red lights because the car is broken or they are in a rush. There was a 23% gap between what they wanted to do and what they actually did. The paper calls this the "Attitude-Practice Gap."
2. The "Magic Key": Training
The study found one thing that made the biggest difference: Training.
- If a worker had been trained before, they were more than twice as likely to handle waste correctly compared to someone who hadn't.
- The Analogy: Think of training like giving someone a map and a compass. Without it, even a good driver gets lost. With it, they can navigate the messy roads of a war-torn city much better.
3. Who Was Doing Well? (The Surprises)
You might think doctors, being the bosses, would be the best at following safety rules. The study found the opposite:
- Doctors: Had the biggest gap between knowing the rules and following them. They knew the rules but were the least likely to follow them strictly.
- Pharmacists, Nurses, and Lab Techs: These groups were actually doing a better job than the doctors.
- Cleaning Staff: They were often the ones who knew the least and practiced the least, likely because they hadn't received enough training.
The Analogy: It's like a sports team where the Coach (Doctor) knows the playbook perfectly but forgets to wear the helmet, while the Assistant Coaches (Nurses/Pharmacists) are the ones actually wearing the gear and playing by the rules.
4. The "Kitchen" Matters (Facility Factors)
The study looked at whether the place where you work matters. It turns out, it matters a lot.
- 19% of the difference in how well people followed the rules was because of the hospital they worked in, not just the person.
- The Analogy: If you are a great chef, but your kitchen has no trash cans, no gloves, and no sink, you can't cook safely. The study found that if the hospital (the kitchen) didn't provide the tools (containers, gloves, boxes), the workers couldn't do their job, even if they wanted to.
5. Three Groups of Workers
The researchers used a computer to sort the workers into three "teams" based on how they acted:
- The High-Risk Team (27%): These workers didn't know the rules, didn't care much, and didn't follow them. They need basic training immediately.
- The "I Know But Can't" Team (33%): These workers knew the rules and wanted to follow them, but they couldn't. Usually, this was because the hospital didn't give them the right tools or they were too busy.
- The Champions (40%): These workers knew the rules, cared, and did them correctly. The study suggests these people should be the ones teaching the others.
6. The Hard Truths Found
- Needle Injuries: Almost 29% of workers said they had been pricked by a needle in the last year.
- Vaccines: Only about 45% of the workers had been vaccinated against Hepatitis B (a serious liver disease).
- Reporting: When workers got hurt, they often didn't report it (only 66% reported it). It's like a player getting hurt on the field but not telling the coach, so the coach can't fix the problem.
Summary
The paper concludes that in this difficult, war-affected setting, knowing the rules isn't enough. You need three things to fix the problem:
- Training: Teach the workers (especially the ones who haven't been taught yet).
- Tools: The hospitals must provide the trash cans, gloves, and boxes.
- Leadership: The "Champions" (the 40% doing a good job) should help teach the others, and the doctors need to step up and lead by example.
The study emphasizes that without fixing the "kitchen" (the hospital resources) and giving the "chefs" (the workers) the right training, the waste will keep piling up, putting everyone at risk.
