Everything there is to know about our research

<aside>

Purpose:

This section brings together what we know about IMPALA's impact: the main results, an independent assessment, what one ward is expected to deliver, and the studies behind it. We show the limits of the evidence alongside the results.

What one standard paediatric ward is expected to deliver per year and over five years, on both the observed and the independently discounted effect.
