Without a complete published description of interventions, clinicians and patients cannot reliably implement interventions that are shown to be useful, and other researchers cannot replicate or build on research findings. The quality of description of interventions in publications, however, is remarkably poor. It is problem for both drug interventions and non-drug interventions, although more of a problem for non-drug interventions, with less than half of trials containing enough information to make them replicable.

To improve the completeness of reporting, and ultimately the replicability, of interventions, an international group of experts and stakeholders developed the Template for Intervention Description and Replication (TIDieR) checklist and guide. The process involved a literature review for relevant checklists and research, a Delphi survey of an international panel of experts to guide item selection, and a face to face panel meeting.

The resultant 12 item TIDieR checklist is an extension of the CONSORT 2010 statement (item 5) and the SPIRIT 2013 statement (item 11). For authors of reports of randomised trials, it is recommended that TIDieR is used in conjunction with the CONSORT checklist: when authors complete item 5 of the CONSORT checklist, they should insert “refer to TIDieR checklist” and provide a separate completed TIDieR checklist. Similarly, for authors submitting protocols of trials, the TIDieR checklist can be referred to when dealing with item 11 of the SPIRIT 2013 checklist (although TIDieR items 10 and 12 are not applicable to protocols as they cannot be completed until the study is complete).

The TIDieR guide provides, for each item, an explanation, elaboration, and examples of good reporting.
