Table 2. SQUIRE: Relevant elements

Assessing the Evidence for Context-Sensitive Effectiveness and Safety



Planning the intervention

  • Describes the intervention and its component parts in sufficient detail that others could reproduce it.
  • Indicates main factors that contributed to choice of the specific intervention (for example, analysis of causes of dysfunction; matching relevant improvement experience of others with the local situation).
  • Outlines initial plans for how the intervention was to be implemented: e.g., what was to be done (initial steps; functions to be accomplished by those steps; how tests of change would be used to modify intervention), and by whom (intended roles, qualifications, and training of staff).


  • Outcomes.
  • Explains the actual course of the intervention (for example, sequence of steps, events or phases; type and number of participants at key points), preferably using a time-line diagram or flow chart.
  • Documents degree of success in implementing intervention components.
  • Describes how and why the initial plan evolved and the most important lessons learned from that evolution, particularly the effects of internal feedback from tests of change (reflexiveness).
