Development and user-testing of a web-based patient decision aid for self-management interventions

Towards the end of the COMPAR-EU project – after completing network meta-analysis, assessing the certainty of the evidence, selecting the most promising interventions for the four different chronic conditions, and formulating recommendations on these interventions – we are now in the process of developing interactive web-based decision aids tools including all of the above information.

COMPAR-EU decision-aids will assist patients to decide on which self-management intervention best suits them. They will help them to compare different intervention options (e.g., how important are the potential desirable and undesirable effects), and prepare them to participate with their health professional in making an optimally informed decision.

We relied on the work conducted by leaders in the field of shared decision-making, including the Ker Unit at Mayo Clinic, and other emerging groups like the MAGIC consortium to identify the main aspects that need to be included and considered in their development. We also reviewed research synthesis in this field, and existing decision aids tools. Finally, after an in-depth brainstorming, we developed a first prototype.

To ensure the usability and understandability, we gathered feedback from a Task Force, a multidisciplinary group including patients, clinicians, methodologists, and other relevant stakeholders. We also assembled an external group of patients who have been involved in previous steps of the COMPAR-EU project. With the Task Force, we held regular meetings in which we presented the tools and their progress, whereas with the patients’ group we conducted a workshop in which we presented the prototype. Finally, we conducted semi-structured interviews with patients. At the moment, we are currently working on making all the necessary changes in the decision aid web-based tools and have an optimal version ready to conduct – in collaboration with OptiMedis – user-testing with patients and health professionals.

This user-testing will allow us to identify errors and areas of improvement by asking both, patients and health professionals, about their experience navigating the web-based decision aid tool. With their feedback, we will finalize the web-based decision aid tools, translate them into six different languages (English, French, German, Spanish, Dutch and Greek) and make them available in the COMPAR-EU platform during 2022.

A review of methods for addressing components of interventions in meta-analysis

Now published: four lay summaries

A lay summary is a brief summary of a research project that is used to explain complex ideas and technical and scientific terms to people who do not have prior knowledge about the subject. They are important not only for patients but also for lay persons and non-specialist medical professionals.

The first four lay summaries are now published! Read more here:
