Andrew J Lloyd,1 Beenish Nafees,1 Eddy Ziani,2 Laurence Nicolas,2 Beth Alice Fordham,1 Benoit Soubeyrand,2 Christoph Bornhöft3 1Patient Reported Outcomes, ICON Plc, Oxford, UK; 2Medical Affairs, Sanofi Pasteur MSD, Lyon, France; 3Practice for Pediatric and Adolescent Medicine, Bensheim, Germany Abstract: Diphtheria, tetanus and acellular pertussis (DTaP) based combined vaccines have led to significant reduction in incidence of several serious pediatric infectious diseases. A new, fully liquid combined hexavalent vaccine has been introduced and has been shown to reduce administration time. This fully liquid vaccine may also be simpler to administer and could reduce handling errors. The present study was designed to understand the value that health care providers (HCPs) place on aspects of injection devices for combined hexavalent vaccine programs in Germany. A discrete choice experiment (DCE) was designed to elicit the views of HCPs regarding hexavalent vaccines. The key attributes of injection devices were identified through a focused literature search and interviews with HCPs. Five key attributes, each with two or three levels were described which included: type of device, experience of this hexavalent vaccine on the German market, preparation time, probability of handling errors, and dosage errors. Physicians (n=150) and nurses (n=150) who administered hexavalent vaccines in Germany completed the survey. Choice data were analyzed using the conditional logit procedure. All attributes were significant and important independent influences on physicians’ and nurses’ choices. Reducing any “probability of dosage errors” was the most important attribute. Both physicians and nurses had a strong preference to reduce preparation time. All other things equal both groups also significantly preferred a fully liquid hexavalent vaccine. They also preferred vaccines that had been on the market for a few years compared to ones that had not (especially the physicians). Additional analyses explored participants’ preferences in more detail through interaction terms. The DCE choice data provide useful insights into how HCPs view each aspect of the vaccination device. Overall, the HCPs preferred fully liquid vaccines. The survey also highlighted the importance of handling and dosage errors, reducing preparation time, and also experience of the HCPs with the use of a vaccine. The survey work included physicians and nurses and explored their views separately. Keywords: hexavalent vaccines, fully liquid vaccines, preferences, handling errors, dosage errors

- Abstract
Objective: Treatment options for psoriasis offer trade-offs in terms of efficacy, convenience, and risk of adverse events. We evaluated patients' preferences with respect to benefit-risk in the treatment of psoriasis., Methods: A discrete choice experiment was conducted in adults from the UK with moderate-to-severe psoriasis using an orthogonal design with 32 hypothetical choice sets. Participants were randomly assigned to one of two surveys with 16 choice sets. Patients' preferences were investigated with respect to the following attributes: reduction in body surface area affected by psoriasis, treatment administration (frequency and mode of delivery), short-term diarrhea or nausea risk, and 10-year risk of developing melanoma or nonmelanoma skin cancer, tuberculosis, or serious infections. A mixed effects logistic regression model generated relative preferences between treatment profiles., Results: Participants (N=292) had a strong preference to avoid increased risk of melanoma or nonmelanoma skin cancer (odds ratio [OR]: 0.44 per 5% increased 10-year risk) and increased risks of tuberculosis and serious infections (both ORs: 0.73 per 5% increased 10-year risk) and preferred once-weekly to twice-daily tablets (OR: 0.76) and weekly (OR: 0.56) or fortnightly (OR: 0.65) injections. Participants preferred avoiding treatments that may cause diarrhea or nausea in the first 2 weeks (OR: 0.87 per 5% increase) and preferred treatments that effectively resolved plaque lesions (OR: 0.93 for each palm area still affected)., Conclusion: All attributes were significant predictors of choice. Patients' preference research complements clinical trial data by providing insight regarding the relative weight of efficacy, tolerability, and other factors for patients when making treatment choices., Competing Interests: Disclosure FM is an employee of Celgene Ltd. AK was an employee of Celgene Corporation at the time of the study. LE, APB, KMJ, CP, and AJL report no conflicts of interest in this work.

- Abstract
Purpose: The aim of this study was to elicit utilities for radioactive iodine-refractory differentiated thyroid cancer (RR-DTC) and evaluate the impact of treatment response and toxicities on quality of life., Patients and Methods: RR-DTC health states were developed based on data from a previous qualitative study and iterative review by clinical experts. Following piloting, health states underwent valuation by 100 members of the UK public during time trade-off interviews. Mean utilities and descriptive distribution statistics were calculated, and a logistic regression analysis was conducted., Results: The demographic characteristics of the study sample were generally reflective of the UK population. Clear differentiation in valuation between health states was observed. No response/stable disease had an adjusted utility value of 0.87, with a corresponding gain of +0.04 following a treatment response and a decline of -0.35 for disease progression. Adverse events were associated with utility decrements between -0.47 (grade III diarrhea) and -0.05 (grade I/II alopecia)., Conclusion: The trade-off interviews derived utility weights show clear differentiation between RR-DTC health states in response to treatment. The values reported in this study are suitable for cost-effectiveness evaluations for new treatments in RR-DTC.

- Abstract
Background: Intermittent catheterization is the gold standard for bladder management in Europe in people with spinal cord injuries. The aim of the present study was to identify and investigate individuals' preferences regarding intermittent self-catheterization (ISC) devices and furthermore investigate the willingness to pay for attributes in ISC devices in the UK, France, and the Netherlands., Methods: A discrete choice experiment survey was conducted to evaluate the patients' perceived value of catheter features. Attributes were selected based upon a literature review of the most important characteristics of catheters and the survey was developed and validated with input from patients and medical experts. Data were analyzed using the conditional logit model whereby the coefficients obtained from the model provided an estimate of the (log) odds ratios of preference for attributes. Willingness to pay was estimated for all levels of the attributes., Results: Two-hundred and eighty-three participants completed the questionnaire and were included in data analysis. Risk of infection had the highest odds ratios as preferred important attribute for all three countries followed by ease of insertion. "Pre-coated catheters" was found to be valued as the most preferred coating technology across all countries. Out of pocket cost was a significant influence on patients' choice., Conclusion: Users of ISC perceive the value of convenience (size of catheter), ease of insertion, and reduced risk of infection as the most important features attached to an intermittent catheter. These results are applicable both for the "classic" ISC user as well as for another broad group of catheter dependent individuals.
