Occupational Sharps Injuries Among Healthcare Workers in Sub-Saharan Africa: Safety Practices, Risk Factors, and Professional Disparities at a Namibian Referral Hospital
A 2020 cross-sectional study at a Namibian referral hospital reveals that over half of healthcare workers experienced sharps injuries, with doctors reporting higher injury frequencies and lower safety compliance compared to nurses, highlighting the urgent need for targeted institutional interventions and improved workplace safety systems beyond mere awareness.

Imagine a hospital as a busy, high-stakes kitchen. In this kitchen, the chefs (doctors) and the servers (nurses) are constantly handling very sharp knives (needles and scalpels) while cooking meals for hundreds of hungry guests (patients). The goal is to feed everyone safely, but sometimes, the chefs or servers accidentally cut themselves. When they do, they risk getting sick from invisible germs on the knives, like HIV or Hepatitis.
This research paper is like a safety inspection report from a specific, very busy kitchen in Namibia called Intermediate Hospital Oshakati. Here is what the inspectors found, explained simply:
The Big Picture: A High-Risk Kitchen
The study looked at 490 kitchen workers (134 chefs and 356 servers). They found that more than half of them (54.7%) had cut themselves at least once while working. This is a lot higher than what you might see in wealthy countries, where safety rules are often stricter and the kitchen is better equipped.
In this Namibian kitchen, cuts aren't just one-time accidents. Many workers get cut repeatedly. About 38% of them get cut between one and three times a year, but some get cut ten or more times. It's like if a chef kept dropping a knife on their foot every week; eventually, they are going to get hurt.
The "Who" and "Where": Chefs vs. Servers
The study noticed some interesting differences between the two groups:
- The Chefs (Doctors): They worked in the most dangerous zones, like the "surgical station" (operating theatre) and the "delivery station" (obstetrics). Because they were doing the most intense, invasive work, they were more likely to get cut in the middle of the shift.
- The Servers (Nurses): They were everywhere, doing a lot of routine tasks like giving shots and drawing blood. While they got cut often, the study found that the chefs were actually more likely to blame their cuts on the environment.
Why Did the Cuts Happen? (The Root Causes)
The workers pointed fingers at several things that made the kitchen unsafe:
- Exhaustion: Many workers said they were working shifts longer than 10 hours. Imagine trying to juggle knives when you are so tired you can barely keep your eyes open. The study found that doctors were much more likely to say, "I got cut because I was working too long."
- Bad Lighting: Some areas were too dark. It's hard to see a tiny needle in the dark, making it easy to slip. Doctors specifically blamed poor lighting for their injuries.
- The "Knowledge vs. Action" Gap: This is a crucial finding. Most workers knew the safety rules (like "don't recap needles" or "wear gloves"). It's like everyone knowing that you shouldn't run with scissors, but doing it anyway because they are in a rush.
- The Surprise: Even though doctors have more education, they were actually less likely to follow the safety rules than the nurses. They were less likely to wear gloves properly and less likely to know exactly how to throw away the sharp trash.
The "Trash" Problem
One of the biggest dangers is what happens after the knife is used.
- The Right Way: Throw the sharp knife immediately into a special, puncture-proof box.
- The Wrong Way: Putting the knife in a regular trash bag (blue bag) or, even worse, sticking it in a pocket.
- The Finding: While most people used the right box, about 22% of workers still "recapped" the needles (putting the cap back on, which is like trying to put a lid on a moving knife).
- The Doctor Difference: Doctors were significantly more likely to throw the sharp knives into the wrong trash bags than the nurses were.
The Good News: Speaking Up
Despite the dangers, there was a bright spot. When someone got cut, 84% of them told the hospital bosses. This is important because it means the "safety culture" is working to some degree; people aren't hiding their injuries out of fear. Furthermore, 91% of those who got cut went to get medical help (called Post-Exposure Prophylaxis) to prevent getting sick. This shows the hospital has a system to help, even if the injuries keep happening.
The Conclusion: It's Not Just About "Knowing Better"
The main takeaway from this report is that you can't just tell people to "be careful." The workers already know the rules. The problem is that the kitchen itself is broken.
To stop the cuts, the hospital needs to:
- Fix the lights so people can see what they are doing.
- Stop overworking the staff so they aren't too tired to be careful.
- Give them better tools (like safety-engineered needles that retract).
- Make sure the "chefs" (doctors) are held to the same safety standards as the "servers" (nurses).
The paper concludes that until the hospital fixes the environment and the systems, simply telling workers to be safe won't stop the injuries. It's like telling a chef to stop cutting themselves while you keep giving them dull knives and turning off the lights.
