Enabling Conditions and Sequencing for Sustainable Prosthetic and Orthotic Care: Development of the ROOTS Framework through Realist Evaluation in Post-Conflict Sierra Leone
Through a realist evaluation of a prosthetic and orthotic care initiative in post-conflict Sierra Leone, this study develops the ROOTS framework, which establishes that sustainable outcomes depend on a specific, non-shortcuttable sequence of foundational local capacity conditions—infrastructure, supply chain reliability, workforce development, and technical quality assurance—rather than prioritizing patient volume alone.

The Big Problem: Building a House Without a Foundation
Imagine trying to build a beautiful, sturdy house. But instead of starting with a solid concrete foundation, you start by painting the walls and buying fancy furniture. You might have a nice-looking house for a few weeks, but the moment a storm hits (or the people who brought the furniture leave), the whole thing collapses.
This is exactly what has been happening with prosthetic and orthotic (P&O) care (artificial limbs and braces) in places like Sierra Leone. For decades, international groups have flown in, donated equipment, trained local doctors, and fitted patients with limbs. They counted their success by how many limbs they delivered.
But once the foreign groups left, the system fell apart. Why? Because they skipped the "foundation." They tried to run a high-tech clinic without reliable electricity, without a steady supply of materials, and without a local team that had been properly trained on standard equipment.
The New Approach: The "ROOTS" Framework
The authors of this paper (a team from MIT and the Sierra Leone Ministry of Health) realized they needed a new way to think about this. They didn't just want to count how many limbs were made; they wanted to build a system that lasts.
They used a method called Realist Evaluation, which is like being a detective trying to figure out: "What conditions had to be true first for the next step to work?"
They developed a framework called ROOTS. Think of it like planting a real tree. You can't just drop a seed in the air and expect a tree. You have to follow a specific order:
- Readiness Assessment (Checking the soil)
- Ordering by Dependency (Planting in the right order)
- Ongoing Vetting (Checking the quality of the water and nutrients)
- Threshold Recognition (Knowing when the roots are strong enough)
- Sustainable Trajectory (The tree standing on its own)
The Four Steps They Took (The "Sequencing")
The paper found that you cannot do these things all at once. You must do them in a specific order, like a chain reaction. If you skip a link, the chain breaks.
1. Fix the "Workshop" (Infrastructure)
- The Problem: Before they could do anything else, the clinic had broken machines, no running water, and unreliable electricity. It was like trying to bake a cake in a kitchen with no oven.
- The Fix: They fixed the building and equipment first.
- The Result: Only after the workshop was functional could they reliably make new limbs.
2. Secure the "Grocery Store" (Supply Chain)
- The Problem: Even with a working kitchen, you can't bake if you don't have flour. For 14 years, the clinic had no reliable way to get materials. They had to use scraps or wait for random donations.
- The Fix: They established a reliable supply chain so materials arrived on time and were the right quality.
- The Result: Now, students could learn to make limbs using standard materials, not random scraps. This made their training actually useful.
3. Train the "Chefs" (Workforce/Education)
- The Problem: You can't have a great restaurant without trained chefs. Before, there were almost no local experts, and the few who existed were retiring with no one to replace them.
- The Fix: Once the kitchen worked and the ingredients were there, they started a formal, accredited training program.
- The Result: They trained 11 new local clinicians who knew how to use the standard tools and materials.
4. The "Quality Control" Team (Vetting)
- The Problem: Sometimes, well-meaning outsiders bring "help" that is actually bad (e.g., equipment that doesn't work in local conditions or materials that are unsafe).
- The Fix: They set up a team to check everything that came into the country before it was used.
- The Result: They stopped bad equipment from entering the clinic, ensuring safety and quality.
The "Magic" Moment: Standing Up for Themselves
The most surprising finding in the paper happened at the very end.
For years, the clinic had been so desperate for help that they accepted anything offered by outsiders, even if it was low-quality or unsustainable. They felt they had no choice.
But once they built their foundation, supply chain, and trained their own team, something changed. A foreign organization came in with a plan that the local team knew was flawed and unsustainable.
The local team said "No."
Without being told to do so by their foreign partners, the local doctors and engineers evaluated the offer, realized it was substandard, and politely declined it. This is what the authors call "Self-Protection."
It's like a child who, once they have learned to cook and buy their own groceries, stops eating food that is spoiled because a neighbor gave it to them. They have the power to say, "We don't need that; we have our own standards now."
The Bottom Line
The paper concludes that you cannot measure success by how many limbs you give out today. If you don't build the foundation first (Infrastructure -> Supply Chain -> Training -> Quality Control), those limbs won't last, and the system will remain dependent on outsiders forever.
The ROOTS framework is a guide for governments and donors: Don't rush the volume. Follow the dependency order. Build the roots first, and the tree will eventually stand tall on its own.
