- 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.
Minimum standards for the certification of patient decision
support interventions: Feasibility and application.

Theoretical Rationales, Current Evidence, and Emerging Issues"
series that appeared in the 2013 November Supplement in BMC Medical Informatics and Decision Making.
- 2013 November Supplement in BMC Medical Informatics and Decision Making.
- The International Patient Decision Aid Standards (IPDAS) Collaboration’s Quality Dimensions:
Theoretical Rationales, Current Evidence, and Emerging Issues.
This 2013 series begins with a paper describing
a) the ten-year evolution of the IPDAS Collaboration itself and
b) IPDAS's 12 core dimensions for assessing the quality of patient decision aids.
Next, 12 papers present an updated theoretical rationale, the current empirical evidence, and
the emerging issues underlying each of these core evaluative dimensions.
Finally, the series closes with a systematic review of the implementation of patient decision support
interventions into routine clinical practice.
A total of 102 authors from 10 countries contributed to this supplement.
- 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.

- 2013 Update of the IPDAS Story
- An update to the overview of the activities of the International Patient Decision Aid Standards (IPDAS) Collaboration
originally presented at the 2011 International Shared Decision Making Conference held in Maastricht, Netherlands.
- 2013 IPDAS email list
- The IPDAS email list, IPDAS@listserv.dartmouth.edu, will be used:
To be added, ask a current member to introduce you by citing your interest and expertise relevant to IPDAS.
If you don’t know a member, see the Who’s Involved? page.
- as a membership register,
- to communicate,
- to agree on a process to convene a Steering Group (vote for chair/members),
- for future research / development of the criteria.

- 2009 IPDASi Assessment
The IPDAS instrument of 47 items was developed to rate the IPDAS criteria
on a 4 point scale from strongly agree to strongly disagree.
IPDASi raters were trained and calibrated to conduct these assessments.

- 2006 Original IPDAS Checklist
- The 64 item Checklist
can be used to rate the IPDAS criteria as present or absent.
Note that some of the 74 individual criteria were combined
(e.g., identical criterion for patients and practitioners).
The small numbers after each item refer back to the original criteria that were voted on.
- The 2-stage Delphi process resulted in 74 of 83 criteria
being retained based on having an importance ranking of 7 or higher on a 1 to 9 scale.

- 2005 Second Round Voting Document [377KB PDF]
- This revised voting document also includes:
- A summary of the 1st round results for the 12 broad criteria
- The equimedian score for each of the 80 criteria in the 1st round of voting. Equimedians were calculated to equalise the effect of the different voter numbers in the 4 key stakeholder groups (policy maker / health plan administrators, patients / consumer representatives, health practitioners, decision aid developers/researchers)
- The frequency counts of the 1 to 9 ratings for each of the 80 criteria in the 1st round of voting
- This document was used to revise the voting website and as a PDF document available on the voting website for those preferring to vote on paper.
- Voters were asked consider the results from the 1st round of voting when re-voting on the importance of each criterion for judging the quality of a patient decision aid.
- 2005 First Round Voting Document [313KB PDF]
- A collection of summary statements for each of the 12 broad criteria with a total of 80 voting items.
- This document was used to create the voting website at Baylor College of Medicine (B Volk and colleagues) and was available as a PDF on the voting website for those preferring to vote on paper.
- Voters were asked to vote on the importance of each criterion when judging the quality of a patient decision aid.
- 2005 Original IPDAS Collaboration Background Document [414KB PDF]
- A summary of the definitions as well as theoretical and empirical links between each of the 12 broad quality criteria and decision quality.
- The 12 broad criteria include: systematic development process, information on options, presenting probabilities, clarifying values, patient stories, disclosing conflicts of interest, delivering decision aids on the Internet, balanced presentation of options, using plain language, information based on scientific evidence, establishing effectiveness.
- The primary evidence sources were the Cochrane Review of 34 randomized controlled trials evaluating patient decision aids with real patients facing health decisions (2003 update) and fundamental studies.
- This document was used to inform the summary statements for each of the 12 broad categories and the identification of the original set of voting criteria.
- It was available during the voting process for voters interested in learning more about the 12 broad criteria.
Very useful for training students.
I ask them to "vote using the 1st round document,
then give them feedback using 2nd round document results."
As well, students developing patient decision aids find the background document very useful.
A O'Connor PhD, Professor at the University of Ottawa (June 2005)
I teach a research course about the theories, study designs,
and methods used to study patients' decision making.
The course includes, but isn't confined to,
the topic of Shared Decision Making/Patients' Decision Aids (SDM/PtDAs).
The individual sections of the IPDAS Collaboration Background Document
are rich reading resources for the students, as we move through the different topic areas
of the course. For example, the principles outlined in Section B
(providing information about therapeutic options)
and in Section C (presenting probabilities) are highly relevant to problems outside
the SDM/PtDA context, such as developing ways to measure the
Minimal Clinically Important Difference that patients would want from a new
therapy that's going to be assessed in a clinical trial.
