an mcda-based patient decision aid for patients with bipolar disorder
DESCRIPTION
How can patients be enabled to participate in decisions concerning their health? How can decisions be improved, concordent with patient values? A new patient decision aid will capitalise on network meta-analysis and single subject research designs to foster better decisions.TRANSCRIPT

• Many personalisation technologies
• Very limited use of technologies

Why can´t I stop my medication?
It really bothers me. I would be much better
without!

was, but I do

Ok, lets try to find the best decision together
What are the benefits and harms you care about?
And how likely are they, with and without medication?

The goal
• Find - together
• the best decision
• for you
![Page 23: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/23.jpg)
And to achieve the goal…
• Find the:
• options
• attributes
• probabilities
• preferences

Four sources of knowledge
Electronic medical record
All the research in the world

Knowledge not tailored to decisions
• All options not directly comparable
• Not personalised
• Not always reliable
• Not always readable
• Tells nothing in itself, without preferences

Part 1 of the work
• Complete two network meta-analyses
![Page 33: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/33.jpg)

Knowledge not operational
• Information about the effects of medicines taken is
• not systematic
• not quantified
• (Often lacking)
• not structured
• not available to the patient
Electronic medical record
![Page 35: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/35.jpg)
A possible solution: An Annalisa decision aid
![Page 36: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/36.jpg)
Enabling continuous registration of attributes
• Example: depressive symptoms
• Patient registers level of depression weekly
• Feeds into the decision aid
• Assessment of the effect of the medication
• continuously and in retrospect

Part 2 of the work
• Developing the Annalisa decision aid
![Page 39: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/39.jpg)

How to evaluate a personalised intervention?
![Page 41: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/41.jpg)
The problem with group designs
• Take considerable time and resources
• No improvement of intervention on-the-fly
• Do not establish causality in the individual

A possible solution: single-subject design
![Page 43: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/43.jpg)
Single subject designs
• Extensive use within behavioural sciences
• Internal validity maintained
• Mimics and feasible within clinical practice
• Not the same as case studies!
![Page 44: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/44.jpg)
Benefits• Assesses effect in the individual patient
• Identifies causal relationships
• External validity comparable to group designs
• Determines efficacy in novel interventions
• Helps optimalise the intervention
• Design and intervention can be adjusted on the fly

3 novelties in this work
![Page 49: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/49.jpg)
Novelty 1:
Complete NMAs and feed the values into the desicion aid
![Page 50: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/50.jpg)
Novelty 2:
• Continuous registration of attributes important to the patient
• in a decision aid
engineered for
distributed decisions
![Page 51: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/51.jpg)
Novelty 3:
• Utilising a single subject research design…
• to evaluate a patient decision aid
![Page 52: An MCDA-based patient decision aid for patients with bipolar disorder](https://reader038.vdocuments.us/reader038/viewer/2022110307/555cb0d9d8b42ab2358b533b/html5/thumbnails/52.jpg)
Flexible yet rigorous
A personalisable:
• decision aid
• assessment tool
• study design
