RESUMEN
OBJECTIVE: To understand the preferences of healthcare providers (HCPs) in Switzerland for pediatric hexavalent vaccine attributes. METHODS: A discrete-choice experiment included a series of choices between 2 hypothetical pediatric hexavalent vaccines with varying attributes: device type (including preparation time and risk of dosage errors), proportion of infants seroprotected against Haemophilus influenzae type b (Hib) at 11-12 months (pre-booster), packaging size, years on the market, and the thermostability at room temperature. Odds ratios (ORs) and conditional relative attribute importance (CRAI) were calculated using random-parameters logit. RESULTS: HCPs (150 pediatricians and 40 nursing staff) in Switzerland were unlikely to choose a vaccine conferring 50% (OR 0.00; 95% CI 0.00-0.00) or 70% (OR 0.01; 95% CI 0.00-0.01) of infants with Hib seroprotection at 11-12 months (pre-booster) compared with a vaccine conferring 90% seroprotection. The odds of choosing a vaccine available on the market for more than 3 years were nearly 5 times the odds of choosing a vaccine available on the market for less than 1 year (OR 4.76; 95% CI 1.87-7.65). The odds of choosing a vaccine in a prefilled syringe were nearly 3 times the odds of choosing a reconstituted vaccine (OR 2.77; 95% CI 1.39-4.15), and the odds of choosing a vaccine with a smaller package size were nearly 2 times the odds of choosing a vaccine with larger package size (OR 1.89; 95% CI 1.23-2.55). HCPs were equally likely to choose vaccines that can stay at room temperature for 6 versus 3 days (OR 1.07; 95% CI 0.73-1.42). According to CRAI, the most important attribute was Hib seroprotection, followed by years on the market, device type, and packaging size. CONCLUSION: Hib seroprotection at 11-12 months was the most important hexavalent vaccine attribute to HCPs in this study.

Study purpose: New treatments for atopic dermatitis (AD) are emerging; however, little is known about the treatment preferences of patients with mild-to-moderate AD. To measure patients' preferences, a cross-sectional, web-based discrete choice experiment (DCE) survey was developed and administered to 300 adults in the United States with a self-reported physician diagnosis of mild-to-moderate AD.Materials and methods: In the DCE, respondents evaluated pairs of hypothetical AD treatment profiles defined by efficacy, risk, and mode and frequency of administration attributes. The DCE data were analyzed using a random parameters logit model. Subgroup analysis was used to investigate preference heterogeneity.Results: The results revealed achieving clear or almost clear skin within 3-4 months of treatment was the most important attribute relative to all other study attributes. The results indicated that a topical cream applied twice daily was preferred to systemic treatments. Subgroup analysis revealed that respondents with lower self-assessed disease burden were more likely to choose topical over systemic treatments and less averse to the risk of pain, burning, and/or stinging from the medicine (all other treatment features remaining equal) than respondents with higher self-assessed disease burden.Conclusion: The results of this study can help inform shared decision-making to manage mild-to-moderate AD.

Aim: To describe development of a shared decision making (SDM) aid in treating primary immunodeficiency diseases (PID) with immunoglobulin replacement therapy (IGRT). Materials & methods: Expert engagement and qualitative formative research informed development. IGRT administration features were prioritized using object-case best-worst scaling (BWS) methodology. The aid was assessed by US adults self-reporting PID and revised following interviews/mock treatment-choice discussions with immunologists. Results: Patients participating in interviews (n = 19) and mock treatment-choice discussions (n = 5) deemed the aid useful/accessible and supported the utility of BWS, with content and BWS exercises refined following participant feedback. Conclusion: Formative research led to an improved SDM aid/BWS exercise, and illustrated how the aid may improve treatment decision making. The aid may help less-experienced patients and facilitate efficient SDM.
Shared decision making and developing a decision aid Shared decision making happens when patients and doctors work together to choose treatment options based on a patient's concerns, preferences, goals and values, as well as medical information. The aim of this project was to develop a decision aid to help patients with primary immunodeficiency diseases (PID), in which part of the body's immune system is missing or doesn't function correctly. This will allow patients to better understand and communicate with the healthcare team on their preferences about immunoglobulin treatments, which fight infection by boosting antibody (protein) levels in the blood. The authors talked to experts and reviewed existing information to decide what treatment features the aid should consider. Patients with PID then tested the aid, and changes were made based on their feedback. Doctors specializing in treating PID also provided their feedback. The final aid was judged to be helpful and easy to use by the participants. With further research, this aid could be used to help inexperienced patients better understand what immunoglobulin treatment features are most important to them, and support shared decision-making between patients and their doctors.

OBJECTIVES: To adapt a patient-reported outcome (PRO) measure, the Western Ontario McMaster Universities Osteoarthritis Index (WOMAC), into efficacy attributes for a discrete choice experiment (DCE) survey designed to quantify the relative importance of endpoints commonly used in knee osteoarthritis (KOA) trials. METHODS: The adaptation comprised four steps: (1) selecting domains of interest; (2) determining presentation and framing of selected attributes; (3) determining attribute levels; and (4) developing choice tasks. This process involved input from multiple stakeholders, including regulators, health preference researchers, and patients. Pretesting was conducted to evaluate if patients comprehended the adapted survey attributes and could make trade-offs among them. RESULTS: The WOMAC pain and function domains were selected for adaption to two efficacy attributes. Two versions of the discrete choice experiment (DCE) instrument were created to compare efficacy using (1) total domain scores and (2) item scores for "walking on a flat surface." Both attributes were presented as improvement from baseline scores by levels of 0%, 30%, 50%, and 100%. Twenty-six participants were interviewed in a pretest of the instrument (average age 60 years; 58% female; 62% had KOA for ≥ 5 years). The participants found both versions of attributes meaningful and relevant for treatment decision-making. They demonstrated willingness and ability to tradeoff improvements in pain and function separately, though many perceived them as inter-related. CONCLUSIONS: This study adds to the growing literature regarding adapting PRO measures for patient preference studies. Such adaptation is important for designing a preference study that can incorporate a clinical trial's outcomes with PRO endpoints.

BACKGROUND: Physicians' preferences for attributes of medical treatments for endometriosis-associated pain have not previously been quantified. METHODS: US obstetrician-gynecologists completed an online discrete-choice experiment survey. In a series of questions, physicians chose a medical treatment for a hypothetical patient with endometriosis experiencing severe, persistent dysmenorrhea, nonmenstrual pelvic pain, and/or dyspareunia. Each question presented two hypothetical medical treatments for endometriosis-associated pain, defined by seven attributes with varying levels. Preferences weights and conditional relative importance (CRI) were calculated using a random-parameters logit model. RESULTS: Respondents (N = 250) had an average age of 53 years; 36% were female. The most important attribute, conditional on the attributes and levels evaluated, was risk of moderate-to-severe hot flashes (CRI, 3.34). In descending order of importance, the CRIs of the other attributes were 2.13 for improvement in nonmenstrual pelvic pain, 2.04 for improvement in dyspareunia, 1.88 for improvement in dysmenorrhea, 1.16 for risk of pregnancy-related complications if pregnancy occurs during treatment, 0.62 for increased risk of bone fracture later in life, and 0.48 for mode of administration. CONCLUSIONS: In addition to valuing pain reduction, respondents prioritized avoiding moderate-to-severe hot flashes, followed by less common and less immediate risks of pregnancy-related complications and bone fracture.

BACKGROUND: Discrete choice experiment is a survey method used to understand how individuals make decisions and to quantify the relative importance of features. Using discrete choice experiment methods, we quantified patient benefit-risk preferences for hypertension treatments, including pharmaceutical and interventional treatments, like renal denervation. METHODS: Respondents from the United States with physician-confirmed uncontrolled hypertension selected between treatments involving a procedure or pills, using a structured survey. Treatment features included interventional, noninterventional, or no hypertension treatment; number of daily blood pressure (BP) pills; expected reduction in office systolic BP; duration of effect; and risks of drug side effects, access site pain, or vascular injury. The results of a random-parameters logit model were used to estimate the importance of each treatment attribute. RESULTS: Among 400 patients completing the survey between 2020 and 2021, demographics included: 52% women, mean age 59.2±13.0 years, systolic BP 155.1±12.3 mm Hg, and 1.8±0.9 prescribed antihypertensive medications. Reduction in office systolic BP was the most important treatment attribute. The remaining attributes, in decreasing order, were duration of effect, whether treatment was interventional, number of daily pills, risk of vascular injury, and risk of drug side effects. Risk of access site pain did not influence choice. In general, respondents preferred noninterventional over interventional treatments, yet only a 2.3 mm Hg reduction in office systolic BP was required to offset this preference. Small reductions in office systolic BP would offset risks of vascular injury or drug side effects. At least a 20% risk of vascular injury or drug side effects would be tolerated in exchange for improved BP. CONCLUSIONS: Reduction in systolic BP was identified as the most important driver of patient treatment preference, while treatment-related risks had less influence. The results indicate that respondents would accept interventional treatments in exchange for modest reductions in systolic BP compared with those observed in renal denervation trials.

BACKGROUND: This study aimed to quantify preferences and risk tolerance for a tick-borne encephalitis (TBE) vaccination. RESEARCH DESIGN AND METHODS: A stated-preference survey instrument was administered to international travelers living in the United States to elicit preferences for a no-cost TBE vaccine when planning an international trip, conditional upon four different qualitative levels of endemic TBE risk. RESULTS: The likelihood of choosing the vaccine increased with a destination's level of endemic risk. Most respondents (94%) would choose to receive the vaccine at the highest risk level presented in the survey (i.e. when multiple TBE cases among humans are reported year after year); 6% of the sample would choose not to receive the vaccine at any risk level. Respondents who engage in outdoor activities were twice as likely as the average respondent to choose vaccination rather than opting out of vaccination, and were one-third more likely than the average respondent to choose to receive the vaccine at the lowest risk level. CONCLUSIONS: Respondents were highly interested in a TBE vaccine, assuming no cost, and most were willing to be vaccinated at all qualitative TBE risk levels. Respondents who participated in outdoor activities were more likely than the average respondent to choose the vaccine.

BACKGROUND: Biologic psoriasis treatments are differentiated by efficacy, side effects, and other attributes. OBJECTIVE: Determine attributes of biologic psoriasis treatments that drive patients' treatment choices. METHODS: Respondents (USA: n = 300; Germany: n = 300) with moderate-to-severe psoriasis completed a discrete-choice-experiment survey, choosing between hypothetical treatments characterized by attributes with varying levels: chance of clear skin after 1 year, number of first-year treatments, first-year risks of mild-to-moderate injection site reaction (ISR) and serious infection, and years of proven efficacy/safety. RESULTS: U.S. respondents most valued clear skin (conditional relative importance, 1.88; p < .05). While other attributes were of generally equivalent importance, ISR risk outweighed serious-infection risk (1.06 vs. 0.70; p < .05). German respondents placed greatest importance on ISR risk (1.61; p < .05) and clear skin (1.49; p < .05). LIMITATIONS: Respondents evaluated hypothetical treatments and were recruited from web panels. CONCLUSIONS: Clear skin and ISR risk are stronger drivers of treatment choice than injection frequency and infection risk.

BACKGROUND: Most adults, and disproportionately fewer African-Americans, have not received herpes zoster (HZ) vaccination despite current recommendations. This study (GSK study identifiers: 208677/HO-17-18066) assessed HZ vaccination preferences among adults aged ≥ 50 years. RESEARCH DESIGN AND METHODS: In this discrete choice experiment, respondents chose among a 'no vaccine' option and two HZ vaccine profiles, characterized by seven attributes, in a series of choice questions. Random-parameters logit results were used to predict likely vaccine uptake. Subgroup and latent class analysis of African-American's preferences were performed. RESULTS: The preference weight for choosing HZ vaccines over no vaccine was statistically significant among the 1,454 respondents (71.9% whites; 25.2% African-Americans). Out-of-pocket (OOP) cost and vaccine effectiveness (VE) were the most important attributes. The African-American and the non-African-American subgroups had statistically significant differences in preferences (χ2 = 59.91, p < 0.001), mainly driven by OOP cost and VE. Latent class analysis identified three groups of African-American respondents with systematically different preferences; two comprised likely-vaccinators, with one being more cost sensitive at lower price thresholds, and one likely non-vaccinators. CONCLUSIONS: For all respondents, HZ vaccine choices were most sensitive to total OOP cost, followed by VE.
PLAIN LANGUAGE SUMMARYWhat is the context?Herpes zoster, or shingles, is a viral disease characterized by a painful, localized skin rash. It affects approximately 32% of US citizens at least once in their lifetime.The risk of contracting shingles increases with age.Most American adults over 50 years have not received the shingles vaccine, and vaccination rates are especially low for African-Americans. What is new?This is the first study to evaluate what drives shingles vaccination decisions among US adults ≥ 50 years of age. We also assessed the differences between African-American and non-African-American adults, and inside the African-American group.In this choice experiment, 1,454 people ≥ 50 years completed a survey of 8 choice questions, as well as questions on their previous experiences with vaccines, socioeconomic, and demographic characteristics. Seven factors were evaluated.We found that American adults preferred to get vaccinated, and the most influential factors were costs and vaccine effectiveness while location of vaccination was the least important. There were differences in preferences between African-American and non-African-American adults, mainly driven by costs and vaccine effectiveness. 3 different groups of African-American adults with systematically different preferences could be identified; two were likely to vaccinate, with one being more cost sensitive at lower price thresholds, and the third was unlikely to vaccinate.What is the impact?Decisions on shingles vaccination appear to be mostly driven by costs, which could be a barrier to those who do not have appropriate insurance, especially among some African-Americans.However, healthcare professionals should continue to educate patients on other vaccine characteristics, as they also influence vaccination decisions.

INTRODUCTION: We evaluated elagolix and leuprolide from the patient's perspective for the treatment of endometriosis-related pain. AREA COVERED: Preference weights from a published discrete choice experiment were used to evaluate preferences for treatment profiles simulating elagolix (150 mg/day and 200 mg/twice-daily dosages) and leuprolide for the treatment of moderate to severe endometriosis-related pain. Sensitivity analyses were conducted by varying the range of risk for pregnancy-related problems, moderate to severe hot flashes, and bone fracture across scenarios. EXPERT OPINION: The 200 mg twice daily dosage of elagolix is more likely to be preferred over leuprolide by patients with moderate to severe endometriosis-related pain in all scenarios explored in the evaluation and sensitivity analyses. The probability that an average respondent would select a treatment was sensitive to increases in risk of moderate to severe hot flashes for leuprolide and possible variations in the risk of pregnancy-related problems for both treatments but was not influenced by an increased risk of bone fracture. CONCLUSIONS: Patients' preferences for treatment of endometriosis-related pain should be evaluated using the benefits and risks of each pharmacological option. Respondents were more likely to prefer the treatment profile similar to 200 mg twice daily elagolix over that of leuprolide in all scenarios.

INTRODUCTION/OBJECTIVES: Multiple modes of administration are available for systemic lupus erythematosus (SLE) treatments. This study examined patient and physician characteristics associated with the choice of weekly subcutaneous (SC) injection or monthly intravenous (IV) infusion for an unspecified SLE treatment. METHODS: This was a cross-sectional, US web-based survey using a direct elicitation, stated-preference methodology (HO-16-16706). Two hundred patients and 200 physicians were asked to choose between IV or SC administration in a hypothetical scenario. Pairwise and multivariate analyses estimated the odds ratio (OR) for the likelihood of choosing SC over IV for respondent characteristics. RESULTS: Among patients, taking non-steroidal anti-inflammatory drugs increased the likelihood of choosing SC injection (OR 3.884), whilst having SLE-related skin problems, a fear of needles or self-injection, and never needing help around the house decreased the likelihood (OR 0.28, 0.13, 0.12, respectively; all p ≤ 0.05). Among physicians, > 95% recommended SC injection for patients who live or work far from an infusion center, prefer SC administration, and never or rarely miss medication doses. Physician characteristics including age and treatment practice also influenced choice. CONCLUSIONS: Patient and physician characteristics influence choice of SC versus IV therapy for SLE. These findings might inform shared decision-making, which could lead to improved patient outcomes. Key Points ⢠Data regarding patient and physician preference for different modes of administration of SLE therapy are sparse. ⢠This cross-sectional, US web-based study showed that patient and physician characteristics influence choice of SC versus IV therapy for SLE. ⢠A degree of disconnect exists between how factors influence patients' choice and how those characteristics influence physicians' choice of SLE treatment mode of administration. ⢠The findings from this study might inform shared decision-making, which could improve alignment between treatment choice and patient preferences, treatment satisfaction, adherence, and improved patient outcomes.

OBJECTIVE: To assess heterogeneity in patient and physician preferences for multiple sclerosis treatment features and outcomes via a discrete-choice experiment. METHOD: Patients with self-reported multiple sclerosis and treating physicians participated in an online discrete-choice experiment. Patients, each considering a better or worse reference condition, and physicians, each considering two patient profiles, chose between hypothetical treatment profiles defined by seven attributes with varying levels: years until disability progression, number of relapses in the decade, mode of administration, dosing frequency, and risks of mild, moderate, and severe side effects. Latent class analysis was used to measure respondent preferences and identify potential subgroups with distinct preferences. RESULTS: Distinct treatment preferences emerged among subgroups of patients (n = 301) and physicians (n = 308). Patients in class 1 (43% of sample) were most concerned about side effects; chief concerns of class 2 patients (57%) were delaying disability progression and avoiding severe side-effect risks. The most important attributes for physicians (by class) were delaying disability (class 1, 45%), avoiding severe side-effect risks and (class 2, 33%), and avoiding all side-effect risks (class 3, 22%). CONCLUSION: Patients and physicians have diverse preferences for multiple sclerosis treatments, reflecting heterogeneity in the disease course and available therapies and the need for shared decision making.
RESUMEN
INTRODUCTION: In 2014, the Advisory Committee on Immunization Practices (ACIP) of the US Centers for Disease Control and Prevention (CDC) recommended 13-valent pneumococcal conjugate vaccine (PCV13) followed by 23-valent pneumococcal polysaccharide vaccine (PPSV23) for all adults aged ≥ 65 years, with a commitment to revisit the recommendation for PCV13 because of declining vaccine-type disease. The Evidence-to-Recommendation framework used by the ACIP includes review of evidence regarding feasibility and stakeholder acceptability, but no surveys of vaccinator preferences have been published in the literature. METHODS: Physicians (N = 700), physician assistants (N = 100), pharmacists (N = 100), and nurse practitioners (N = 100) who recently prescribed, administered, or recommended adult pneumococcal vaccine were surveyed in March 2018. Object-case best-worst scaling was used to assess preferences among potential recommendation scenarios: retaining the then-current 2014 recommendation without a scheduled re-evaluation, retaining with a scheduled re-evaluation, revising PCV13 to Category B (retaining PPSV23 as Category A), removing PCV13 (retaining PPSV23 as Category A), and removing both PCV13 and PPSV23. RESULTS: Providers' most preferred recommendations were retaining the 2014 recommendation with another planned re-evaluation (52.6%) and retaining the then-current recommendation without planned re-evaluation (40.0%). Few preferred changing PCV13 to Category B (3.2%), removing PCV13 (3.7%), or removing both pneumococcal vaccines (0.5%). CONCLUSIONS: The majority of vaccinators surveyed preferred to retain the 2014 recommendation, either with another scheduled reassessment or indefinitely. FUNDING: Pfizer, Inc.
RESUMEN
OBJECTIVES: To quantify patient preferences for endometriosis-associated pain treatments and risk tolerance in exchange for pain reduction and to explore whether preferences vary on the basis of patient characteristics. METHODS: US women with a self-reported physician diagnosis of endometriosis and moderate to severe dysmenorrhea and nonmenstrual pelvic pain (NMPP) completed an online discrete choice experiment survey. Each choice question had a pair of hypothetical treatments characterized by attributes with varying levels: improvements in severe dysmenorrhea, severe NMPP, and severe dyspareunia; mode of administration; and treatment-related risks of pregnancy-related problems, bone fracture later in life, and moderate to severe hot flashes. A random-parameters logit model was used to quantify preferences and the attributes' conditional relative importance. RESULTS: A total of 250 women (mean age 34 years) completed the survey. The conditional relative importance of attributes was 3.66 for risk of moderate to severe hot flashes among respondents with and 3.58 among respondents without experience with moderate to severe hot flashes; 1.70, 1.49, and 1.48 for improvements in dyspareunia, NMPP, and dysmenorrhea, respectively; 0.60 for risk of pregnancy-related problems; 0.53 for mode of administration; and 0.49 for bone fracture risk. Preference weights for bone fracture risk levels were not statistically significantly different. In exchange for a greater improvement in dysmenorrhea from severe to mild (vs moderate), respondents without a history of hot flashes accepted a greater increase in the risk of moderate to severe hot flashes (38%) than did respondents with this history (16%). CONCLUSIONS: Respondents placed the greatest weight on risk of hot flashes, followed by improvements in dyspareunia, NMPP, dysmenorrhea. Bone fracture risk did not drive preferences.

OBJECTIVES: Adherence to injectable disease-modifying treatments in patients with multiple sclerosis (MS) impacts outcomes and can be influenced by perceptions of treatment efficacy, side effects, injection frequency, and the duration of injection. This study aimed to quantify preferences for selected attributes of injectable treatments among individuals with MS in the United Kingdom and France. METHODS: Respondents with a self-reported diagnosis of MS completed an online discrete-choice-experiment survey, consisting of a series of treatment-choice questions. Each choice question presented two hypothetical treatments, each with six attributes (years until disability progression, relapses in the next 4 years, injection time, injection frequency, flu-like symptoms (FLS), and injection-site reactions), each with various levels. Mixed-logit regression analysis was used to estimate preference weights for attribute levels and to calculate the relative importance of changes in treatment attributes (vertical distance between preference weights). Minimum acceptable efficacy estimates indicate improvement in efficacy that respondents would require in exchange for worsening injection frequency and FLS. RESULTS: In both countries, 100 respondents completed the survey. In the United Kingdom and France, respectively, improving the time until disability progression from 2 to 4 years, reducing injection frequency from "daily" to "every 2 weeks", and reducing FLS from 3 days after every injection to none had a relative importance of 2.9 and 2.6, 3.0 and 3.5, and 2.5 and 3.1. Given the ranges included in the study, changes in these attributes were more important than most changes in other attributes assessed. CONCLUSIONS: Reductions in the injection frequency of MS treatments and FLS can be as important to patients as improvements in treatment efficacy.

PURPOSE: Although the World Health Organization recommends universal rotavirus immunization, uptake of the vaccine is low in Poland and Hungary, where it is not covered by the National Immunization Program. This study aimed to quantify mothers' preferences for vaccines preventing children's diarrheal illness and to examine whether willingness to vaccinate varies with working status. METHODS: Mothers of children aged <3â¯years living in Poland and Hungary completed an online discrete-choice experiment survey. In each of 9 choice questions, respondents indicated whether they preferred no vaccination or one of two hypothetical vaccine profiles described in terms of 6 features. Vaccine preference parameters were estimated for working and non-working mothers using a random-parameter logit model and were used to calculate the relative importance of changes in vaccine features. RESULTS: 350 mothers in Poland and 350 mothers in Hungary were surveyed. Of the attributes evaluated, changes in vaccine cost were most important in both countries, followed by changes in severity of illness prevented, vaccine effectiveness, mode of administration, duration of illness prevented, and number of doses. Mothers in both countries had a strong preference for vaccination versus no vaccination, which was more pronounced among working mothers. In Poland, working mothers placed less weight on effectiveness, illness severity, and cost than non-working mothers and were more likely to rate disruptions in work, child care, and routines as important reasons to vaccinate. In Hungary, working mothers were statistically significantly less likely to opt out of vaccination than non-working mothers. Preference for vaccination itself, relative to improving vaccine effectiveness (from 50% to 90% effective), was 7 times greater among working than among non-working mothers in Poland but was not considerably different between working and non-working mothers in Hungary. CONCLUSIONS: Polish and Hungarian working mothers are more likely to vaccinate children against diarrheal illness than non-working mothers.

BACKGROUND: Many travelers to regions with endemic infectious diseases do not follow health authorities' recommendations regarding vaccination against vaccine-preventable infectious diseases, before traveling. The determinants of individual travelers' decisions to vaccinate before traveling are largely unknown. This study aimed to provide this information using a discrete choice experiment (DCE) administered to four types of German travelers: (1) business travelers; (2) travelers visiting friends and relatives (VFR); (3) leisure travelers; and (4) backpackers. METHODS: A DCE survey was developed, pretested and administered online. It included a series of choice questions in which respondents chose between two hypothetical vaccines, each characterized by four disease attributes with varying levels describing the of risk, health impact, curability and transmissibility of the disease they would prevent (described with four disease attributes with varying levels of risk, health impact, curability and transmissibility), and varying levels of four vaccine attributes (duration of protection, number of doses required, time required for vaccination, and vaccine cost). A random-parameters logit model was used to estimate the importance weights each traveler type placed on the various attribute levels. These weights were used to calculate mean monetary equivalents (MMEs) of changes in each attribute (holding all others constant) and of hypothetical disease-vaccine combinations. RESULTS: All traveler types' choices indicated that they attached the greatest importance to the risk and health impact of disease and to the vaccine cost whereas the other disease and vaccine attributes were less important for their decisions about travel vaccines. An option of not choosing any of the vaccine-pairs presented was rarely selected indicating that travelers' generally prefer to be vaccinated rather than not. The MMEs of changes in vaccine attributes indicated a very high variability between the individual travelers within each type. CONCLUSIONS: The travelers' responses indicated strong preferences for selecting vaccination rather than opting out of vaccination, and disease risk, health impact and vaccine cost were the most important features for vaccine choice.

INTRODUCTION: Understanding patient preferences for attributes of type 2 diabetes mellitus (T2DM) medications may help explain how the attributes differentially affect patient perceptions and behaviors. In this survey, we quantified the relative preferences among patients in Germany and Spain in separate analyses. METHODS: A stated-preference, discrete-choice experiment (DCE) survey was designed to elicit preferences for T2DM treatment attributes among patients with self-reported T2DM and who reported being prescribed T2DM medication for > 2 years. Patients recruited from an online national consumer panel completed an online survey. The survey presented choices between eight pairs of hypothetical T2DM treatments defined by seven attributes: chance of reaching target hemoglobin A1c (HbA1c) level; reduced risk of serious heart attack or stroke; frequency of hypoglycemia; risk of gastrointestinal (GI) problems; weight change; mode of administration (oral or injectable); dosing frequency. Data were analyzed using random-parameters logit. Minimum acceptable benefit (MAB) was defined as the minimum increase in the probability of reaching target HbA1c for which respondents would accept less desirable levels of other attributes. RESULTS: In Germany and Spain, 474 and 401 respondents completed the survey, respectively. DCE analysis showed that risk of GI problems was most important to German respondents. MAB analysis found that respondents would require a 56 percentage point increase in the probability of reaching their HbA1c target to offset a change from 0% to 30% risk of GI problems. For Spanish respondents, mode of administration was the most important attribute. These respondents would require a 59 percentage point increase in the probability of reaching their HbA1c target to offset moving from oral to injectable medications. CONCLUSIONS: Respondents in Germany and Spain were willing to trade efficacy for improvements in side effects and mode of administration. Given the variety of T2DM medications currently available, the results suggest that careful discussion about patient preferences could help improve patient satisfaction with T2DM treatment.
RESUMEN
BACKGROUND: This study aimed to assess the influence of disease- and patient-related factors on surgeons' decisions to refer patients with early-stage breast cancer (EBC) for neoadjuvant systemic therapy (NST). METHODS: An online survey of United States surgeons evaluated the influence of selected disease- and patient-related factors on surgeons' decisions, rated their influence (individually and in combination), and provided a relative ranking of jointly considered factors using best-worst scaling. RESULTS: The participants in this study were 100 licensed surgeons. The surgeons referred approximately 25 % of EBC patients for NST to improve surgical management. Approximately 75 % of the surgeons agreed that NST is important for EBC, if only to improve surgical management. More than half were "very likely" to refer EBC patients for NST based on anatomicopathologic factors. Less than 50 % were "very likely" to do so when considering tumor phenotype factors. Tumor size and lymph node status were ranked highest in hypothetical patient scenarios. Regarding combinations of factors, the importance of any single factor varied according to the combinations presented. Less than half of the respondents were "very familiar," and half were "somewhat familiar" with NST guidelines for breast cancer. More than half of the respondents were unaware that findings have shown achievement of pathologic complete response (pCR) after NST to be associated with improved survival. CONCLUSIONS: Surgeons' decision to refer for NST is strongly driven by surgical management goals. Anatomicopathologic factors are more influential than tumor phenotype. However, no single disease or patient factor consistently drives the decision to refer for NST. Surgeons' awareness of the association between pCR achievement and longer survival could be improved.
