The innovation and evaluation cross-cutting theme is a collaboration between public health consultants, academic public health, and the Public Health England Knowledge and Intelligence Team. The theme builds on the successful public health theme of CLAHRC CP that has provided commissioners and researchers with advice on research-based service evaluation and population health. We aim to support high quality systematic reviews with international impact, data modelling and evaluation of complex interventions, and will provide research support the EAHSN’s ‘implementation of innovation’ role.
