4. The Study
Mixed-methods study examining the navigation
of uncertainty about policy decision making in
four cancer control scenarios:
Approval and funding of new drugs
Mammography screening for women aged 40 to
49 years
Prostate specific antigen (PSA) screening
HPV vaccination programs
4
5. Methods
Focus groups with
women about mammography screening (n = 46)
men about PSA screening (n = 47)
Key informant interviews with policy makers
(n = 29)
Development of a policy decision making aid
5
6. Methods – Drug Scenario
Qualitative interviews with officials (n = 16) who
influence or make decisions about cancer drug
policy in Canada:
cancer agencies (n = 7)
ministries of health (n = 4)
organizations that evaluate and recommend
drugs (n = 4)
patient advocacy organizations (n = 1)
Convergent interviewing technique

8. Evidence – Clinical (RCTs)
Priority reviews
Approvals on Phase II data only
Early trial closures
Crossover designs
Open-labeled (unblinded) trials
Surrogate outcome measures (e.g., Progression-
Free Survival, Quality of Life)
Does clinical efficacy predict real-world
effectiveness?
9. Evidence - Economic Analyses
Uncertainty not quantified
ICER thresholds are absent or not transparent
Not subjected to same rigour or scrutiny as
clinical evidence
Economic models built by drug manufacturers
Uncertainty in economic analyses are
compounded when clinical evidence is weak/
uncertain
10. Values
“Physicians give me the most trouble because they
wear different hats and the hat they are most
comfortable wearing is being their patient’s
advocate. They tend have a hard time putting on
the hat of ‘public funding for the societal
overview.’ If we have restricted funds, do we try to
do the best for everyone, or do we do exceptionally
for one group and leave others out in the cold?”
11. Values
“If it’s a mom who has a child who is going be
starting kindergarten in three months, is that
where you want to take her so she can see her
child go to kindergarten for the first time? Most
of us would say we’d spend however much money
to do that, but then are we taking away that
funding from somebody that you can extend their
life by five years with a drug that has better
survival benefits? It becomes really tricky
because you have a confined funding envelope.”

15. Focus on the Evidence
“We fund based on the best evidence we have at
a point in time.”
“Our reimbursement criteria needs to align with
what the evidence says.”
16. Evidence vs. Values
“We want evidence to inform, but evidence
doesn't make the decision. Any process like this
has various people's values and perspectives,
and we've tried to find systems that ensure fair
and equitable decisions are made.”
“We have a very strong evidence-based decision-
making framework that takes into consideration
the clinical and economic evidence, but it also
takes into consideration some of the patient
values as well.”
17. pCODR : Strengths
Many provinces didn’t have the internal expertise
to do their own evidence reviews
All provinces get the same recommendation at
the same time
Governments and cancer agencies are working
closer together
Comparatively transparent process
Provides clinician and patient input
18. pCODR: Some challenges
Recommendations aren’t rank-
ordered/prioritized
ICER threshold is not transparent
Provinces with internal expertise used to be able
to implement new drugs sooner pre-pCODR
19. Pricing Negotiations
Especially for drugs with poor cost-effectiveness
(i.e., marginal benefits and high costs)
pan-Canadian Pharmaceutical Alliance
Risk sharing/pooling with manufacturers and/or
private insurers
“pay-for-performance” agreements with
manufacturers (company rebates $ for patients
that don’t benefit)
20. Formulary Management
Approval only for very specific indications
Case-by-case approvals
Conditional approvals to allow for collection of
additional evidence to attempt to resolve
residual uncertainty
e.g., Coverage with Evidence Development
22. Any action is still a decision
“When you don't have enough information to
make a decision, it doesn’t mean you shouldn’t
make a decision. Life goes on. It's almost better
to make an educated decision—meaning you
weigh the information you have and then decide
to do something—than it is to sit and do
nothing.”
23. Next steps
Study limitations
Uncertainty Assessment and Navigation (U-ANT)
Multiple sclerosis (CCSVI/Liberation Therapy)
24. Conclusion: Managing Transparency
Insights from Risk Comm.
Transparency needs
contextualization
Need to be open about
the nature and type of
uncertainty
People can accept
evolving information
Need to build a culture of
flexible policy review ScienceCartoonsPlus.com
