Obstetric Referral Practices and Health System Factors in Public Health Centres of Addis Ababa, Ethiopia: A Mixed-Methods Study
This mixed-methods study of 50 public health centres in Addis Ababa reveals that while referral systems are largely functional, high obstetric referral rates—particularly in facilities lacking caesarean section services—are driven by limitations in labour monitoring tools, variable clinical skills, and risk-averse practices, suggesting a need for targeted interventions to reduce unnecessary referrals.

Imagine the healthcare system in Addis Ababa, Ethiopia, as a massive network of small neighborhood fire stations (Health Centres) and a few large, fully-equipped fire departments (Hospitals). When a fire starts, the neighborhood station tries to handle it. But if the fire gets too big or dangerous, they must call for backup and send the situation to the big department. This process is called a referral.
This study looked at how well these 50 neighborhood fire stations are set up to send emergencies to the big departments, and more importantly, how often they are actually sending them.
Here is the breakdown of what the researchers found, using simple analogies:
1. The Fire Stations Are Mostly Ready (The Hardware)
The researchers checked if the neighborhood stations had the right tools to make a call.
- The Good News: 80% of the stations were "functional." They had working phones, lists of which big department to call, and even ambulances (the fire trucks) 84% of the time.
- The Glitch: Just because the fire truck is parked in the garage doesn't mean it's ready to roll. Sometimes the trucks were shared with other stations, ran out of gas, or the driver wasn't available. Also, while the stations could send the patient away, they rarely got a "return receipt" or a call back from the big hospital to say, "Hey, we got them, and here is what happened." It was like sending a letter and never knowing if it was delivered or what was inside.
2. The "Over-Calling" Problem (The Stats)
The study found that 32% of all pregnant women coming to these neighborhood stations were sent to the big hospitals.
- The Expectation: Experts say only about 10–15% of pregnancies usually need that level of high-tech help (like a C-section).
- The Reality: The stations were sending women to the big hospitals more than double the expected amount.
- The Difference: Stations that didn't have their own C-section machines sent even more people away (39%) compared to the ones that did have the machines (21%). It's as if the stations without the big tools were panicking and sending everyone to the experts, even when they might have been able to handle it themselves.
3. Why Are They Sending So Many People Away? (The Human Factor)
The researchers interviewed the midwives and managers to find out why this was happening. They found three main reasons, which act like a perfect storm:
- The "Broken Compass" (The Partograph): Midwives use a chart called a "partograph" to track labor, kind of like a weather map for a storm. The study found this map was often misleading. It would show a "storm warning" (the action line), prompting the midwife to send the woman away, but when the woman arrived at the big hospital, the storm had actually passed, and she delivered normally. The tool wasn't predicting the danger accurately.
- The "Skill Gap": Some midwives felt unsure about their own skills, specifically in checking how open a woman's cervix was. If you aren't 100% sure you can measure the progress, it's safer to send the patient to the expert.
- The "Fear of Blame" (Accountability): This was the biggest driver. The midwives and managers said they were terrified of being blamed if a mother or baby died. The system was so strict about accountability that the safest choice for the worker was to send the patient away early, even if the risk was low. It's like a driver who sees a tiny crack in the windshield and immediately calls a tow truck, not because the car will crash, but because they are terrified of getting in trouble if it does crash later.
The Bottom Line
The study concludes that the neighborhood fire stations in Addis Ababa have the equipment (ambulances, phones, forms) to do their job, but they are over-using the emergency services.
The problem isn't that they can't call for help; it's that they are calling for help too often because:
- Their "weather maps" (charts) are outdated and give false alarms.
- They lack confidence in their own skills.
- They are playing it safe to avoid getting blamed for bad outcomes.
The authors suggest that to fix this, they need better maps (updated tools), better training (confidence), and a system where people aren't punished for honest mistakes, so they feel safe handling cases locally when they can.
