Using IPDAS

Presented in a number of different ways, the criteria of the International Patient Decision Aid Standards (IPDAS) can be used for assessing the quality of patient decision aids.

2015 – Feasibility and Application of Proposed Certification Criteria
  • Specifying minimum standards for patient decision support interventions is a feasible development. However, it remains unclear whether the minimum standards can be applied to interventions designed for use within clinical encounters and to those that target screening and diagnostic tests.
  • Reference: Minimum standards for the certification of patient decision support interventions: Feasibility and application. Durand MA, Witt J, Joseph-Williams N, Newcombe RG, Politi MC, Sivell S, Elwyn G. Patient Educ Couns. 2014 Dec 31. pii: S0738-3991(14)00531-X. doi: 10.1016/j.pec.2014.12.009.
2013 – Proposed Certification Criteria
  • A 44 item subset of the original checklist was proposed with criteria classified as qualifying (n=6), certifying (n=10), and quality (n=28). The subset were chosen using a 2 stage Delphi process with participants asked if the omission of an IPDAS criteria would lead to a risk of harmful bias and potential negative impact on patients' decision making.

Joseph-Williams N, Newcombe R, Politi M, Durand MA, Sivell S, Stacey D, O'Connor A, Volk RJ, Edwards A, Bennett C, Pignone M, Thomson R, Elwyn G. Medical Decision Making. 2013 Aug 20;34(6):699-710.
2009 – IPDASi Assessment
  • Based on the original IPDAS checklist, an instrument was developed to rate the IPDAS criteria on a 4 point scale from strongly agree to strongly disagree. IPDASi raters have been trained and calibrated to conduct these assessments.
  • Reference: Assessing the quality of decision support technologies using the International Patient Decision Aid Standards instrument (IPDASi).

PLoS One. 2009;4(3):e4705.
2007 – IPDAS Checklist used in the Decision Aid Library Inventory (DALI)
  • A 30 item subset of the original checklist (rated as yes, no, unknown or not applicable) included only the items that scored highest (9 out of 9) during voting. Developers can register their patient decision aids in DALI and as part of the process they are prompted to use the checklist. The A to Z Inventory of publicly available patient decision aids shows the checklist results. Before being included in the A to Z Inventory, there is an administrative review and approval.
