Unattractive choices/trade-offs are sometimes the only
chance for a patient to survive, live longer or die a less
awful death

Patient preference studies are important for us as
advocates because they enable us to influence key health
system decisions in the interest of patients
Although it is still very limited and doesn’t happen in a systematic way, there is an increasing interest
in incorporating patient preferences into decision making processes.
Therefore, we as advocates need to understand:
What patient preference studies are
What we can achieve for our patients through them
How we can develop them
How and when in the process we can have the highest impact, where we need it the most

Preferences vary a lot depending on who expresses them
In the following example:
Drug A:
• 50% of patients will be alive in 3
years
• all patients will be dead in 8 years
Drug B:
• 85% of patients will be dead in 2
years
• 15% patients with long-term survival
From a regulatory perspective, drug A
might be better because more patients
respond longer
However, some patients may prefer
treatment B because of the rare chance
of surviving

They vary from one stakeholder to another, from one
disease to another, and even within one single disease
Needs and preferences have historically been captured
in general as “the patient voice”
However, there are clear subgroups within single
diseases with very different preferences and risk
attitudes
In this example:
• Considerable heterogeneity
• Severe toxicity ranked higher among younger,
working, and looking after dependent family
members and who had more frequently
experienced severe toxicity

No-one could or should decide on behalf of individual or
subgroups of patients, which of these nasty options they prefer!
Patient preferences tell us what certain subgroups of
patients value the most when it comes to their treatment
WHAT outcomes of a medical product
patients value the most
HOW MUCH these outcomes are valued by
patients

Our role as advocates…
Provide knowledge of the disease pathway and direct
interaction with patients
Work on protocol to make sure it reflects the core
questions and what is acceptable to patients
• Survey acceptability (length, complexity)
• Sensitivity (e.g. survival questions)
Recruit patients from within our membership
Utilise findings for external engagement of patient
organisations with industry, regulators, payers and
policy-makers
Help involved stakeholders understand how to
determine what an acceptable risk is and
whether an unknown risk is acceptable

benefit-risk attributes of MM treatments
To quantify the value of benefit-risk

Survey
To identify patient-relevant benefit-risk attributes
• To quantify value of attributes
• To compare preferences elicited by two different preference methods
• To understand how preferences vary with patient characteristics
Conclusions
Patient Preferences vary from one stakeholder to another, from one disease to
another, but also within one single disease, forming sub-groups with
preferences that are clearly different
Patients know best what to trade between the bad and the ugly, and
whether they prefer an unknown risk to a known unsatisfying outcome
• No stakeholder should express patient preferences on their behalf
• Data not directly gathered from patients should not have the same weight
Patient preferences are becoming a key element of the decision-making
process
Patient advocates need to understand patient preference studies well and
have a clear strategy on how to become involved in generating these data

But for cancer patients this looks a bit different. Unattractive choices are sometimes the only chance
Therefore, it is really important that these preferences are captured accurately to inform important health system decisions.
Patient preferences are increasingly incorporated by decision-makers. But still not systematic.
Therefore, advocates need to understand how it works
Expressing a preference is a value judgement, and therefore it is only natural that every stakeholder has a different preference depending on their objectives and environment
So whose preferences should decision-makers take into account?
Perspectives not only vary from one stakeholder to another, from one disease to another, but also within one disease from one patient or subgroup of patients to another
Patient perspectives are very unique. No other person could or should decide what a patient prefers –not even advocates or carers.
So what do patient preferences actually tell us?
We need to make sure the results have an impact. For this, external expertise might be necessary/useful
Who should set the framework of what patients should decide on
Who decides whether a risk is sufficiently clear to ask a patient about their preference
Who decides whether choosing a totally unknown risk over a known shitty benefit is a valid choice
Who decides whether patients need to be protected against their own “desperation”. And who decides what is a “desperate” choice or an informed and conscious choice
Is a desperate choice not a legitimate one when all other options are awful?
DCE: discrete choice experiment
SW: Multiple criteria decision analysis swing weighting
Increasing the quality of the study protocol:
Understanding the clinical context of the disease
Identification of patient-relevant attributes
Feasibility of qualitative and quantitative method
Amount and type of information given to patients
Understandability of questions and attributes
Organizational:
Patient recruitment
Identifying clinical partners
Increasing the quality of the interpretation of the results:
Interpretation of the results (workshop): what do they mean, why are they there?
Disseminating study results back to patient community
