Thank you to the British Journal of General Practice for pointing me in this direction. HANDI is a project launched by the Royal Australian College of General Practitioners in 2013, to promote effective non-drug treatments. Now the RCGP is partnering with the RACGP to bring this approach to the UK.
The HANDI resource collects evidence based non-drug interventions relevent to and practical for GPs. Many of the interventions on the webpage are common-sense, and practical. Many of them are treatments I already use or prescribe, like the Epley manoevere, or wet combing for headlice. There are other recommendations that I had previously dismissed, not realising that there was an evidence base.
Delivering non drug interventions in practice promotes health literacy and reduces clinical dependence; for these interventions to be effective, patients and families will need to understand how they will help, and can apply the learning in the future.
