Technical and Scale Efficiency of Secondary-Level Hospitals in Ethiopia: A Data Envelopment Analysis
A Data Envelopment Analysis of 12 secondary-level hospitals in Ethiopia reveals widespread technical and scale inefficiencies, indicating that these facilities could reduce inputs by 34% and increase outputs by 85% without compromising service levels, potentially saving 192.5 million ETB through targeted improvements in human resources and medical supply management.

Imagine Ethiopia's health system as a massive, bustling relay race. For years, the runners at the starting line (the small health centers) and the middle of the track (primary hospitals) have been studied to see how fast they run. But the runners at the crucial second-to-last leg—the secondary hospitals—have been running in the dark. No one had ever checked their stopwatch or measured their stride until now.
This study decided to shine a bright light on 12 of these secondary hospitals, which are designed to serve huge crowds of 1 to 1.5 million people each. The researchers acted like efficiency detectives, using a mathematical tool called Data Envelopment Analysis (DEA). Think of DEA as a super-smart coach who looks at every team's equipment (money, staff, medicine) and their race results (patients treated) to figure out who is wasting energy and who is running perfectly.
The Big Reveal: Most Teams Are Wasting Fuel
The results were a bit of a shocker. Out of the 12 hospitals studied, only 2 (17%) were running with perfect efficiency. They were the gold-medal winners, getting the maximum possible output from their resources.
The other 10 hospitals? They were running with the brakes on.
- The Average Score: The typical hospital scored 0.66 on technical efficiency.
- What that means: Imagine a car that uses 10 gallons of gas to drive 100 miles. These hospitals could have driven that same 100 miles using only 6.6 gallons. In plain English, the average inefficient hospital could have cut its spending on staff, medicine, and equipment by 34% without treating a single patient less!
The "Under-Utilized" Problem
Here is the twist: The problem wasn't just that they were wasting fuel; it was that they were driving empty buses on a highway meant for full ones.
- The study found that almost all the inefficient hospitals were operating under "Increasing Returns to Scale."
- The Analogy: Imagine a bakery that only bakes 10 loaves of bread a day but has a giant industrial oven and 20 bakers. It's a waste of space and staff! If that bakery baked 100 loaves, the cost per loaf would plummet.
- The data showed a scale efficiency score of 0.15. This suggests these hospitals have the capacity to increase their output (treat more people) by 85% right now, using the exact same amount of money and staff they currently have. They aren't too small in physical size; they are just under-utilized.
The Money Trail: Where the Savings Hide
If we could fix these 10 inefficient hospitals, how much money would we save? The study calculated a potential saving of approximately 192.5 million Ethiopian Birr (ETB). That is a massive pile of cash that could be redirected to help more people.
Where would this money come from?
- Human Resources: The biggest chunk of savings (62.3 million ETB) comes from better managing staff.
- Drugs and Supplies: The second biggest chunk (49.9 million ETB) comes from smarter use of medicine and medical tools.
- Together, these two categories make up more than half of the total potential savings.
What the Study Does NOT Say
It is important to know what this study doesn't tell us, so we don't get the wrong idea.
- It does not say the hospitals are failing at their job. The study explicitly states that these hospitals could treat more people without needing more money. The issue is not a lack of funding, but a lack of utilization.
- It does not suggest closing hospitals. Because the hospitals are "under-sized" (operating below optimal scale), the solution is to get more people through the doors, not to shut the doors.
- It does not measure quality. The study looked at numbers (costs and visit counts), not how happy the patients were or how well the doctors cured them. The authors admit this is a limitation; a hospital could be efficient at treating many people poorly, but this study didn't check for that.
- It is a snapshot, not a movie. The data is from one specific year (Ethiopian Fiscal Year 2009). It tells us how things looked then, but it doesn't prove how they will look next year or if these trends are permanent.
The Takeaway
The authors suggest that the path forward isn't necessarily asking for more money from donors or the government. Instead, the "win" lies in efficiency. By managing staff better, stopping waste in the supply room, and finding ways to get more community members to use these hospitals (perhaps by improving how people are referred there), Ethiopia could unlock huge amounts of value.
The study concludes that while the current situation shows significant waste, the potential to fix it is real. It's not a magic trick, but a clear roadmap: stop wasting the fuel you already have, and fill the empty seats on the bus.
