What Do Patients Really Want?-Eliciting preferences case study-
SICK OR TREAT SESSIONS, OCTOBER 2015
![Page 2: 'What do patients want?' by Dr. Simon Fifer - Sick or Treat Sessions](https://reader035.fdocuments.net/reader035/viewer/2022062904/587ed5421a28abdb198b5eff/html5/thumbnails/2.jpg)
How do we elicit patient preferences ?
Discrete Choice Experiments

Discrete Choice Experiments (DCEs) requires decision makers to select their preferred option from a set of competing
alternatives (which collectively form choice tasks)
Broadband Choice
![Page 4: 'What do patients want?' by Dr. Simon Fifer - Sick or Treat Sessions](https://reader035.fdocuments.net/reader035/viewer/2022062904/587ed5421a28abdb198b5eff/html5/thumbnails/4.jpg)

Respondents are shown multiple choice tasks, over which the features of the alternatives are
systematically varied, allowing for a determination of how each of the features impacts upon the
preferences of a sampled population.
Student Choice

DCEs are now used by many fields to understand and model the trade-offs and preferences revealed
by the choices that people make.

Case Study:Chronic Lymphocytic Leukaemia (CLL)
Approx. 1,300 people diagnosed each year most common type of leukaemia generally a rare disease - 0.8% of all cancer mortality rate 375 / year

Our approach
This research seeks to outline a methodological approach to elicit and quantify patient values in a
systematic way for the purpose of treatment evaluation

Sampling
• Currently recruited 65 patients – 25% through Healthcare team (mainly specialists) – 75% through advertising

CLL Disease Burden: Emotional and Physical Impact
CLL symptoms*: tiredness / fatigue [particularly leading up to requiring treatment; when immune system is low; when patient has low oxygen levels – this can lead to patient having to cease physical activity and hobbies (e.g. exercise / sport); patients commonly require more sleep
Co-morbid conditions: including high temperature and pneumonia (attributed to a depleted immune system) – this can lead to hospitalisation for antibiotic treatment and monitoring (mentions of 3 days- 6 weeks hospital stay)
Side effects: with chemotherapy (particularly nausea) – a high dependence on caregiver during this time)
Inability / reduced capacity to work: can cause financial stress and can change family dynamics (i.e. wife has to work)
Physical Impact Frustration: due to CLL being a chronic
condition, currently no cure, prior therapy unsuccessful, impact on daily life (i.e. inability to participate in activities; e.g. play sport)
Concern / worry: CLL described as a ‘mental challenge’ (future is uncertain – reluctance to make plans; patients can never feel ‘free’); concerns about dying and impact of this on family, an unpredictable condition (can flare up unexpectedly)
Paranoia: patients are vulnerable to infections and are concerned about visiting places where they may be ‘at additional risk’ (e.g. hospitals; shops)
Disappointment: discouraging blood tests results (i.e. residual leukaemia cells)
Anxiety / nervousness: particularly when obtaining blood test results
Shock: initially, upon diagnosis Lack of motivation: a reduction in ‘drive’ -
more so when undergoing chemotherapy treatment
Emotional Impact

CLL Disease Burden: Social and Financial Impact
Financial impact of CLL has been variable for patients
A few patients reported a low impact (due to financial security, part-time employment, Medicare, private health insurance)
A couple of patients reported a high financial burden due to:
Inability to work Attempting to find a cure
(experimenting with alternative medicine has been costly)
Substantial costs incurred by carer (based in rural location) when visiting patient in hospital (i.e. travel; accommodation, meals, laundry)
Financial Impact Unable / less able to socialise: too
unwell during periods of treatment (i.e. chemotherapy), tiredness / fatigue due to CLL
Some social withdrawal: one patient reported feeling defined by their CLL (change in personality - have become more subdued); preference for one to one vs. group situations (one report of feelings of alienation in larger social settings; preference for socialising only with family /and close friends)
Nutritional demands can affect type of socialising: e.g. avoid going to restaurants (preference for home cooked meals); very limited alcohol intake
Social Impact

FDA Study – Weight Loss Device
Patient preferences considered for the first time in FDA decision to approve first-of-kind obesity device
N=540 United States adults with body mass index (BMI) e30 kg/m(2) evaluated trade-offs among effectiveness, safety, and other attributes of weight-loss devices in a
scientific survey.
DCEs were used to quantify the importance of safety, effectiveness, and other attributes of weight-loss
devices to obese respondents.

FDA Study – Weight Loss Device
Developed a tool to estimate the minimum weight loss acceptable by a patient to receive a device with a given risk profile and the maximum mortality risk tolerable in
exchange for a given weight loss
