The Role of Pharmacy and Inventory Management in Reducing Medication Waste: A Comparative Analysis of the "Sharek" Platform in Saudi Arabia

Imagine a massive, high-tech library where the books aren't stories, but life-saving medicines. In this library, there's a tricky problem: sometimes, a shelf gets overfilled with books that nobody is reading right now, while other shelves are empty. If those extra books sit too long, they get "expired"—they become useless and have to be thrown away. This isn't just a waste of paper; in the real world, it's a waste of money and a tragedy because people who need those medicines might not get them. This is the world of pharmacy and inventory management, a field dedicated to making sure the right medicine is in the right place at the right time, without letting anything rot on the shelf. The big question researchers ask is: How do we stop throwing away perfectly good medicine just because it's sitting in the wrong building?

This paper dives into a specific solution used in Saudi Arabia called the "Sharek" platform. Think of "Sharek" as a super-smart, digital "bring-and-buy" market for hospitals. Instead of letting medicine expire in one hospital's basement, the system lets them "share" it with another hospital that needs it right now. The authors, a team affiliated with the Security Forces Hospital Program in Dammam, looked at the records of this platform to see if it actually works. They didn't just guess; they counted the actual medicine that was saved. Their main finding is that the platform successfully moved 37,466 medication units that were about to expire to places where they could be used. They suggest that this system, combined with sharp-eyed pharmacists who watch the shelves, can cut down the amount of wasted medicine by about 70% to 75%.

The Story of the "Sharek" Platform

To understand why this matters, let's look at the problem first. Medicines have expiration dates, like milk in a fridge. If a hospital orders too much, or if a patient's needs change, that medicine might sit on a shelf until it goes bad. When that happens, it's a double loss: the hospital loses the money they spent buying it, and the environment suffers from the waste. In Saudi Arabia, there are many different types of hospitals—some run by the government, some by the military, and some by universities. Before the "Sharek" platform, these groups didn't really talk to each other about their extra stock. It was like having five different kitchens in the same house, where one kitchen is throwing away fresh bread while the next kitchen is baking its own, even though they could have just shared.

The "Sharek" platform, managed by the National Unified Procurement Company (NUPCO), changed the game. It acts like a central hub where hospitals can list their extra medicine and see what others need. The researchers in this paper decided to investigate how well this digital hub performed. They looked at 30 specific transactions that happened between 2023 and 2024. They didn't just look at the numbers; they looked at what was being shared.

The results were quite lively. The platform helped move 37,466 medication units away from the trash can and into the hands of patients. Who got the medicine? Mostly hospitals run by the Ministry of Defense (18,430 units) and the Ministry of Health (14,728 units). But it wasn't just one type of drug. The "Sharek" platform moved everything from heart medicines like Irbesartan and Nifedipine to painkillers, antibiotics, and even drugs for mental health. It was a true mix-and-match success story.

The Magic of Timing and Tracking

One of the coolest parts of the study is how it measured the "before and after" of using the platform. Before "Sharek," the researchers estimated that hospitals were losing between 800 and 1,200 units of medicine every month to expiration. That's like throwing away a whole crate of fresh fruit every single month! After the platform started working, that number dropped to just 150–300 units. That's a massive drop, suggesting a 70–75% reduction in waste.

In terms of money, this is huge. Before the platform, hospitals were losing an estimated $15,000 to $22,000 every month on expired stock. Afterward, that loss shrank to $3,000 to $6,000. The authors calculate that this could save the system between $180,000 and $264,000 every single year.

But the paper also highlights a subtle but important change: the timing of the transfers. Before, when hospitals did swap medicine, it was often a last-minute scramble, happening only 2–3 months before the drug expired. With "Sharek," the system allows for transfers much earlier, giving the receiving hospital 6–12 months to use the medicine. This is like swapping a banana that's about to turn brown for one that's still perfectly yellow, giving you plenty of time to eat it before it spoils.

The Human Element: The Pharmacists as Guardians

The paper makes it clear that technology alone isn't a magic wand. The "Sharek" platform is just the tool; the real heroes are the pharmacists. These are the people who act as the guardians of the medicine shelves. The authors explain that pharmacists play a critical role by:

• Watching the clock: They constantly check expiration dates.
• Predicting the future: They try to guess how much medicine will be needed so they don't order too much in the first place.
• Spotting the extras: They are the ones who say, "Hey, we have too much of this, let's list it on Sharek!"

Without these vigilant humans, the digital platform would be empty. The study suggests that when pharmacists are trained to use these systems and are given good inventory tools (like computers that send alerts when a drug is getting close to expiring), the whole system works much better.

What's Next?

The authors are careful not to say the problem is completely solved. They point out that there are still hurdles, like making sure all the different hospitals can talk to each other smoothly and getting everyone to follow the same rules. They suggest that in the future, we could use even smarter technology, like Artificial Intelligence, to predict exactly how much medicine is needed so that overstocking doesn't happen in the first place.

In short, this paper tells a story of how a simple idea—sharing what you have with someone who needs it—can save a lot of money and a lot of medicine. By using the "Sharek" platform and empowering pharmacists to be proactive, Saudi Arabia is showing that with a little bit of organization and a lot of teamwork, we can stop throwing away the things that could save lives. It's a reminder that sometimes, the best way to solve a big problem is just to start sharing.
