Childsmile Evaluation

Lead Contacts: Professor Lorna Macpherson

Overview

Childsmile is the national child oral health improvement programme for Scotland. 
It was developed as pilot studies from 2006/7, building on an established national supervised toothbrushing programme in nursery schools. By 2011, an integrated programme was in place in all NHS Boards across the country.

An integrated theory-based evaluation led by the University of Glasgow, funded by the Scottish Government, has been an important feature of the programme from its outset.

Since August 2013, the Childsmile approach has been adopted in Chile, England, Israel, Malawi, the Netherlands, countries of Southeastern Europe and Vanuatu.
In 2019, the European Commission recognised the Childsmile methodology as public health best practice 


Evaluation approaches

Aims
To understand and tackle the social determinants of childs oral health and reduce child oral health inequalities. 

Process evaluation
The in-depth, mixed-methods process evaluation assesses how closely the programme is operating according to how it was envisioned initially, ie whether the anticipated changes in service provision and behaviours, necessary for child oral health improvement, have occurred. This includes, for example: activity levels for fluoride varnish applications in education and dental practice settings; dental registration and attendance rates; toothbrushing activity; DHSW and other community-based early years’ activity. Where necessary, research is conducted to investigate the barriers and facilitators for the implementation of component parts of the programme. Identification of these factors can facilitate ongoing refinement to enhance programme delivery still further.

Outcomes
Outcomes from the programme are being investigated mainly via a pioneering big data linkage project. This involves linking multiple routine administrative national health and education datasets to create a birth cohort to evaluate the complex multiple interventions of Childsmile with a range of health and education outcomes.
An economic evaluation, investigating the cost-effectiveness of the programme and its components, accompanies this work. Furthermore, an embedded, randomized control trial of the nursery fluoride varnish programme – Protecting Teeth @ 3 trial10 – has recently been completed.
