How to use evidence

Good research evidence – from multiple, high-quality trials – is the best way to gauge the effectiveness of an intervention with a specific population or in a specific set of circumstances.

But that’s only part of the picture.

To make a truly evidence-based decision, the intervention also needs to meet the requirements or expectations of the population or clients you aim to help. And it must be appropriate for the resources you have available, including the knowledge and skills of the people who will be delivering the intervention.

In other words, evidence of effectiveness from trials is not enough – an intervention needs to make sense within your context and organisation, and with your target population.
