In the UNICEF’s recent Narrowing the Gap II study, a group of over 50 countries was included; one of the key areas of analysis was the measurement of changes in supply, demand and quality bottlenecks for these 50+ countries over a period of around 5 years. This allowed to identify the best results found among these countries in reducing each of bottlenecks analysed. This has thus provided us with a benchmark of “good practices” that serve us as realistic benchmarks of what is feasibly within a medium-term scenario.
“Operational coverage frontiers” for the most disadvantaged quintiles is the change in effective coverage of evidence based high impact interventions (health, nutrition and WASH, HIV etc.) that is considered feasible if their bottlenecks are reduced with the same proportion as observed recently in the most disadvantaged quintiles in best- performing countries. This represents a medium term benchmark based on “best practices” in reducing bottlenecks.
