Understanding drivers of antibiotic misuse in Senegal and Tanzania: Implications for antimicrobial stewardship

This study identifies that antibiotic misuse in Senegal and Tanzania is primarily driven by systemic barriers such as long wait times, high costs, and limited diagnostics, necessitating multi-faceted stewardship interventions that address these financial and access frictions alongside behavioral factors.

Imagine a world where the tiny, invisible soldiers we call antibiotics—the medicines that help us fight off bacterial infections like strep throat or a bad ear infection—are losing their superpowers. This isn't a sci-fi movie; it's a real crisis called antimicrobial resistance (AMR). Think of bacteria like a group of mischievous pranksters. When we use antibiotics correctly, we zap them. But if we use them too much, or use them when we don't need them, the pranksters learn how to dodge the zap. They evolve into "superbugs" that regular medicines can't kill. This is a huge problem because, without working antibiotics, simple infections could become deadly again.

To stop this, experts use something called "Antimicrobial Stewardship." You can think of this as a strict rulebook for a game. The rulebook says: "First, check if the enemy is actually there (diagnosis). Then, pick the right weapon (prescription). Finally, hand it over only if you have the right ticket (pharmacy)." The goal is to make sure antibiotics are used only when absolutely necessary, so the superbugs don't get a chance to evolve. But in many places, the game is being played by a different set of rules, and that's exactly what this story is about.


The Great Antibiotic Detour: A Tale of Two Cities

Researchers from PATH, a global health organization, decided to investigate why people in Senegal and Tanzania were skipping the "rulebook" and taking shortcuts with antibiotics. They didn't just look at doctors; they followed the entire journey of a sick person, from the moment they feel a symptom to the moment they swallow a pill. They called this the "antibiotic delivery pathway," which is a fancy way of saying: "The path you take to get better."

They found that the path is full of potholes, detours, and speed bumps that force people to break the rules. Here is what they discovered, step-by-step.

Step 1: The "Pharmacy-First" Shortcut
Imagine you have a stomach ache. The rulebook says you should go to a doctor first. But the researchers found that about 50% of the patients they asked said, "Nah, I'll just go to the pharmacy." Why? Because the hospital felt like a maze.
In the public hospitals, the wait was brutal. In Senegal, 30.8% of patients waited more than 60 minutes, and in Tanzania, 18.5% waited that long. Meanwhile, private clinics were faster, but they cost more. The public hospitals were also far away. Patients in Senegal traveled 25.1 km to get to public care, compared to just 5.63 km for private care. In Tanzania, the gap was 14.5 km versus 5.5 km.
When the wait time gets too long or the bus fare too high, people decide the "pharmacy-first" shortcut is the only way to survive the day.

Step 2: The Pharmacy Gatekeepers
So, you go to the pharmacy. The pharmacist is supposed to be the gatekeeper, checking your ticket (prescription) before letting you buy the medicine. But the study found that the gate is often left wide open.
Only 6% of pharmacists said they frequently sent people without prescriptions back to a doctor. In fact, 20.6% said they never sent them back. Even though 69.2% of pharmacists believed patients would listen if told to go see a doctor, the reality was different. When researchers asked patients at pharmacies, only 2 out of 56 said they would actually go see a doctor if told to.
Pharmacists admitted they were stuck. They knew they shouldn't sell antibiotics without a prescription, but they also knew that if they didn't, they'd lose customers and money. In the private sector, 100% of pharmacists said they often get asked for antibiotics without a prescription.

Step 3: The Doctor's Dilemma
Even when people do go to the doctor, the "diagnosis" part of the rulebook often gets skipped. The rulebook says: "Test first, then prescribe." But 86.2% of doctors admitted they prescribed antibiotics before getting test results.
Why? Because patients often refuse the tests. In Tanzania, 73.3% of doctors said patients refused diagnostic tests, usually because the tests were too expensive or took too long. Only 43.2% of patients actually expected to be tested before getting medicine.
It's a vicious cycle: Patients don't want to wait or pay for a test, so doctors just guess what's wrong and hand out the medicine.

Step 4: The Lab and the Prescription
The researchers also looked at the labs. They found that 74.3% of lab technicians said patients asked for tests without a doctor's referral. In the private sector, this jumped to 87.5%. Sometimes, the technicians even gave advice on which antibiotics to take, stepping into the doctor's shoes because the doctors were hard to reach.
When doctors did write prescriptions, they often faced pressure from patients to give them the "strongest" or "best" antibiotics, even if they weren't the right ones. Nearly 90% of doctors said patients asked for specific antibiotics that didn't match the official guidelines.
In Tanzania's private sector, only 38% of the antibiotics prescribed were the "Access" category (the basic, first-line drugs recommended by the World Health Organization). This is way below the target of 60%, meaning doctors were handing out stronger, more expensive drugs way too often.

Step 5: The Final Handoff
Finally, the patient gets the medicine. In Senegal, 66.2% of people leaving pharmacies had a prescription. In Tanzania, that number dropped to 35.8%.
The study also found that pharmacists often doubted the doctors' handwriting or dosage instructions. In Tanzania's private sector, it took pharmacists an average of 46.7 minutes to raise a concern about a bad prescription, compared to just 16.25 minutes in public facilities. This delay meant that sometimes, the wrong medicine got through just to keep the line moving.

The Big Picture: Why the Rules Break

The main takeaway from this paper is that antibiotic misuse isn't just about people being ignorant or doctors being constrained by system limitations. It's about the system being broken.
The researchers suggest that the "pharmacy-first" culture and the skipping of tests aren't because people hate science; it's because the health system is too slow, too far away, and too expensive. When the "official" path is a marathon of waiting and paying, people naturally choose the "shortcut" path, even if it's risky.

The study concludes that you can't just train doctors to follow the rules better. You have to fix the road. To stop the misuse of antibiotics, we need to fix the wait times, lower the costs, make tests easier to get, and make sure pharmacists feel safe sending people back to the doctor without losing their customers. Until then, the shortcut will remain the most popular route, and the superbugs will keep getting stronger.
