The 'Tanahashi model' of health service coverage evaluates effectiveness of coverage through a cascade of sequential steps. Which of the following is the correct final step in this model?

• A Contact coverage
• B Accessible coverage
• C Acceptable coverage
• D Effective coverage ✓

Explanation

The Tanahashi model describes five sequential coverage steps: availability coverage, accessibility coverage, acceptability coverage, contact coverage, and finally effective coverage. Effective coverage is the proportion of the target population who receive a health intervention that has a proven effective impact. It is the most stringent measure and represents the ultimate goal of health service delivery.
