Part 9: How does CNA work on real problems? · Module 20
A conjunctural road to low DTP3
What Drives Low DTP3 Coverage?
Suppose you study low DTP3 coverage with four gap conditions: untrained staff, recent stockout, broken cold chain, and no supervision. A common CNA result is a single bundle, where low coverage needs several gaps to gang up at once.
Interpretation: DTP3 collapses where a stockout, a broken cold chain, and absent supervision all land in the same place. No single gap is the villain. This is conjunctivity, the gangs-up idea, showing its face in a real coverage indicator. It also tells you that fixing only one of the three may not be enough on its own.
What You Will Be Able to Do
- Frame a low-DTP3 question for CNA.
- Read a single-pathway (conjunctural) solution.
- Explain why no one condition in the bundle is enough alone.
