Evidenced based public Health
Imagine you are working in a health department in a country of your choosing. In your work, you have been asked to consider the applicability of the findings of a Cochrane review for your health
The background for this request is that a new policy is being developed to improve vaccination rates and the head of the Vaccination Section needs information about the effectiveness of various
interventions in order to decide where investment should happen.
It is not your job to make a recommendation – only to consider the applicability of the interventions to your context, health system and society.
First, select which country you are in. It is sensible to choose a country and health system you know well or where you can get reliable information about vaccination. This can be from grey
literature, that is, in government reports or articles which provide data on what is happening in your country.
The five questions are:
1. Were the studies included in the systematic review conducted in the same setting or were the findings consistent across settings or time periods? 2. Are there important differences in on-the-ground realities and constraints that might substantially alter the feasibility and acceptability of an option? 3. Are there important differences in health system arrangements that may mean an option could not work in the same way? 4. Are there important differences in the baseline conditions that might yield different absolute effects even if the relative effectiveness was the same? 5. What insights can be drawn about options, implementation, and monitoring and evaluation?
