1. “But WHAT did they actually do?” Poor reporting of interventions: a remediable barrier to research translation Associate Professor Tammy Hoffmann @Tammy_Hoffmann thoffmann@bond.edu.au

2. Waste in Research >85% of research is wasted due to: Chalmers, I. & Glasziou, P., 2009. Avoidable waste in the production and reporting of research evidence. Lancet, 374(9683), pp.86–9.

3. Reporting guidelines Although ultimate responsibility lies with researchers, editors “should take all reasonable steps to ensure the quality of the material they publish”. Guidelines for reporting health research are important tools to facilitate this.

4. Reporting Guidelines Specify a minimum set of items needed for a complete and clear account of study methods and funding. Adherence to guidelines improves the accuracy and transparency of publications. Some journals refer authors to guidelines in ‘Instructions to Authors’ – has much less impact on reporting quality than requiring authors to adhere to them

5. EQUATOR Network www.equator-network.org/ A guide for promoting the use of reporting guidelines in your journal: http://www.equator-network.org/wp- content/uploads/2012/12/Reporting-guidelines-in-journals-August- 2013.pdf

6. Most frequently used guidelines CONSORT – for reporting of randomised controlled trials (RCTs) - currently >23 000 trials in PEDro PRISMA – for systematic reviews and meta-analyses STARD – for diagnostic accuracy studies STROBE – for observational studies in epidemiology

7. Without a complete description of an intervention… other researchers cannot replicate or build on research findings for effective interventions, clinicians, patients, and other decision makers are left unclear about how to reliably implement the intervention

8. Do journals provide sufficient instructions to authors? Audit of ‘Instructions to Authors’ for 106 journals 58% mentioned the CONSORT statement + 6% also mentioned the CONSORT extension statements Only 15 (14%) specifically mentioned the reporting of interventions Of these, nearly all provided non-specific instructions e.g. “Describe study procedures, including any interventions…” Hoffmann, T.C., English, T. & Glasziou Paul, P., 2014. Reporting of interventions in randomised controlled trials: an audit of journal Instructions to Authors. Trials, 15(20).

9. How big is the problem?

10. Individual checklist items and overall rating of completeness of the intervention description % of interventions rated as adequately described Hoffmann, T., Erueti, C., & Glasziou, P. (2013). BMJ. 347:f3755

11. Aim of TIDieR To improve the completeness of reporting, and ultimately the replicability, of interventions  emphasis is on trials, but the guidance is intended to apply across all evaluative study designs http://www.bmj.com/content/348/bmj.g1687.long

12. TIDieR development process Literature review Potential checklist items were generated from: – Existing checklists – Forward and backward citation searching of each published checklist – Research analysing the quality of intervention reporting in trials and related literature Two round modified Delphi consensus survey Face-to-face consensus meeting
