Healthcare Supply Chain Reverse Logistics in Public Hospitals of Dire Dawa, Ethiopia: Implementation Status and Associated Factors
This study reveals that while upstream processes like inspection and storage are relatively functional, the implementation of reverse logistics in public hospitals in Dire Dawa, Ethiopia, is suboptimal overall due to critical weaknesses in downstream transportation and disposal systems, which are significantly associated with poor infrastructure and limited technological support.

Imagine the healthcare supply chain as a giant, bustling river system. The "forward flow" is the main current: medicine is manufactured, shipped to warehouses, and delivered to hospitals to help sick people. This part is well-known and usually gets all the attention. But every river has a reverse current, too. This is reverse logistics: the journey of things going back the other way. It's what happens when a medicine expires, gets damaged, or is recalled. It's the path of returning unused stock or safely disposing of hazardous waste. Think of it as the river's way of cleaning up its own mess. If this reverse current is weak or blocked, toxic sludge (expired drugs and medical waste) can pile up, poisoning the environment and wasting precious money. In places with fewer resources, this cleanup crew is often understaffed and under-equipped, making the whole system risky. This study dives into that specific "cleanup crew" to see how well it's actually working.
The Story of the Upstream and Downstream River
Researchers Beyene Dereje Degefa and Asnakech Lechissa Debele decided to investigate the "reverse river" in two major public hospitals in Dire Dawa, Ethiopia: Dilchora Referral Hospital and Sabian General Hospital. They wanted to know: Is the system for handling returns and waste working, or is it clogged? They talked to 208 health professionals, from pharmacists to logistics officers, and looked at the rules and reality on the ground.
Here is what they found: The system is like a car with a brand-new engine but flat tires. The "upstream" parts of the process—where the hospital first checks, sorts, and stores the bad or expired medicines—are actually doing a pretty good job. The "downstream" parts—moving those items away and getting rid of them—are where the system breaks down.
The Strong Start: Sorting and Storing
When it comes to the beginning of the reverse journey, the hospitals are doing well. The staff are good at spotting unfit medicines, labeling them correctly, and keeping them in a secure, designated storage area.
- The average score for inspection and selection was 3.25 (on a scale where higher is better).
- The average score for storage was even higher at 3.86.
It's like having a very organized garage where you can easily find the broken toys and keep them locked away safely. The staff knows what to do with the items once they are identified.
The Weak Link: The Journey and the Trash Can
However, once the items need to leave the garage, things get messy. The study found that transportation is the weakest link, with a low average score of 2.18. The vehicles used to move these hazardous items often aren't suitable, and the conditions during the trip aren't safe. It's like trying to move a box of broken glass in a truck with no suspension and no cover; the risk of a spill or accident is high.
The disposal phase (getting rid of the waste for good) was also only "moderate," scoring 2.83. While the hospitals have committees and guidelines on paper, the actual execution is struggling. The biggest hurdles?
- No designated disposal areas: There isn't a specific, safe place to put the waste before it's destroyed.
- Long procedures: The paperwork and steps to get permission to dispose of waste take too long.
- Lack of technology: They don't have good digital systems to track these items as they move, making it hard to know where everything is.
What Makes the System Fail?
The researchers didn't just guess; they used math to figure out exactly what causes the system to fail. They found that if a hospital has poor transportation practices, it is 4.60 times more likely to have a broken reverse logistics system overall. If the storage systems are inadequate, the risk jumps 3.10 times. Weak disposal practices increase the risk by 2.50 times, and the absence of dedicated disposal areas makes failure 3.40 times more likely.
Interestingly, the study found that having more experienced staff or better initial inspection skills didn't automatically fix the problem if the trucks and trash bins weren't working. The physical infrastructure and the process of moving things out are the real bottlenecks.
The Human Side of the Story
Through interviews, the researchers heard stories that explained the numbers. Staff members said they often hear about "reverse logistics" in meetings, but they don't have clear training or guidelines on how to do it. One staff member noted, "There is a clear gap in managing surplus materials… some items expire while waiting for demand." Another pointed out that while they have committees to decide on disposal, coordinating with environmental offices is a nightmare, sometimes leading to waste sitting around because no one will take it.
The Bottom Line
The paper concludes that the reverse logistics system in these Ethiopian hospitals is "partially functional." It's strong at the start (sorting and storing) but collapses at the finish line (transporting and disposing). The authors suggest that to fix this, hospitals need to invest in better trucks, build proper disposal facilities, speed up the paperwork, and teach the staff how to use digital tracking systems. Without fixing the downstream flow, the hard work done upstream is wasted, leaving the healthcare system vulnerable to financial loss and environmental danger.
