Evaluation of a pharmacist-led audit and feedback intervention to reduce Gentamicin prescribing errors at admission in neonatal inpatient care in Kenya: A controlled interrupted time series study
This controlled interrupted time series study in Kenya found that while a pharmacist-led audit and feedback intervention did not significantly reduce gentamicin prescribing errors in isolation, it was associated with a positive trend in reducing error rates relative to control hospitals that lacked pharmacist involvement.

The Big Picture: A Recipe for Mistakes
Imagine a busy hospital nursery (the Neonatal Unit) where sick newborns are treated. The doctors and nurses there have to give a very specific medicine called Gentamicin to fight infections. Think of this medicine like a very precise recipe: if you add too much, the baby could get poisoned; if you add too little, the infection won't go away.
In many hospitals in Kenya (and around the world), getting this "recipe" right is hard. The study found that about 15% of the time, the medicine was prescribed incorrectly. It was like a chef accidentally adding salt instead of sugar, or doubling the amount of flour by mistake.
The Experiment: The "Pharmacist Coach"
The researchers wanted to see if they could fix these mistakes. They set up a three-year experiment involving 22 hospitals.
- The Problem: In these hospitals, the people writing the prescriptions are often junior doctors or interns who rotate (switch jobs) every few months. They are like new drivers learning to drive a bus; they are busy, tired, and often lack a senior instructor right beside them.
- The Plan: The researchers tried a new approach called "Audit and Feedback."
- The Control Group (6 Hospitals): These hospitals got a standard monthly report, like a generic "scorecard" in the mail. It told them, "You made X mistakes this month."
- The Test Group (16 Hospitals): These hospitals got the same scorecard, but with a special twist: a Pharmacist (a medicine expert) became a "coach." This pharmacist didn't just send the report; they held meetings, gave training seminars, and tried to be a champion for getting the medicine right.
What Actually Happened? (The Twist)
The researchers hoped the "Pharmacist Coach" would act like a personal trainer, helping the team get fitter and stop making mistakes. However, the results were a bit surprising and complicated.
1. The "Coach" Didn't Show Up to Practice
The plan was for the pharmacists to be very hands-on, joining WhatsApp groups with the doctors and using a special smartphone app to give instant feedback.
- Reality Check: The pharmacists were already overwhelmed with their own heavy workload. They didn't join the WhatsApp groups, and almost no one downloaded the smartphone app. It was like hiring a personal trainer who promised to come to your house every day, but they never showed up, and you never opened the door. The "enhanced" coaching mostly just looked like the standard mail-in reports.
2. Mistakes Kept Rising Everywhere
When the researchers looked at the data, they found that mistakes were actually increasing in all hospitals, whether they had the "coach" or not.
- Imagine a classroom where the teacher tries a new method to stop students from spelling errors. Unfortunately, the number of spelling errors went up in every single class, regardless of the method used.
3. The Silver Lining: A Slower Rise
Here is the one small win. While mistakes went up everywhere, they went up slower in the hospitals with the Pharmacist Coach compared to the ones without.
- The Analogy: Imagine two cars driving down a hill with bad brakes (the rising error rate). Both cars are speeding up. However, the car with the Pharmacist Coach had slightly better brakes, so it didn't speed up quite as fast as the other car.
- The Data: Compared to the control group, the test group had about 7% fewer errors during the intervention and 8% fewer errors after it ended. It wasn't a total fix, but it was a difference.
Why Didn't It Work Better?
The paper explains a few reasons why the "Pharmacist Coach" couldn't save the day:
- Too Many New Drivers: The junior doctors rotate every 3 months. Just as a coach teaches a driver, the driver leaves and a new one arrives. The coach has to start over constantly.
- Not Enough Coaches: There was often only one pharmacist for the whole hospital, trying to watch over hundreds of babies. They simply didn't have enough time to check every single prescription personally.
- Confusing Rules: Sometimes the rules for calculating the dose were tricky (using birth weight vs. current weight), and the guidelines didn't always cover every complicated situation a sick baby might have.
The Bottom Line
The study concludes that simply adding a pharmacist to give feedback and training did not stop the mistakes from happening. In fact, mistakes continued to rise across the board.
However, the presence of the pharmacist did slow down the rate of mistakes compared to hospitals that just got a standard report. The researchers suggest that in places with high staff turnover and limited resources, you can't just "coach" your way out of a problem; the system itself needs to be stronger to handle the constant flow of new staff and sick babies.
In short: The "Pharmacist Coach" idea was a good try, but the system was too chaotic for it to work perfectly. It helped a little bit, but it didn't solve the problem.
