Patient preferences for glucagon-like peptide-1 receptor-agonist treatment attributes
The importance of patient-centered care in the management of type 2 diabetes mellitus (T2DM) is widely advocated. Understanding the attributes of T2DM medications important to patients is thus essential for effective management, in order to limit disease progression. This literature review aimed to identify studies comparing patient preferences, based on process and outcome attributes, between GLP1-receptor agonist (RA) profiles and between GLP1 RA and insulin profiles. MEDLINE, Embase, PsycINFO, and the Cochrane Library (2005-present) were searched for studies in patients with T2DM or the general population that compared preferences for GLP1 RAs or GLP1 RAs versus insulin using contingent valuation, conjoint analysis (discrete-choice experiments [DCEs], willingness to pay), rating-based approaches of specific attributes, standard gamble, or time trade-off. Studies comparing drug A versus drug B without explicit attribute valuation were excluded. Ten records met eligibility criteria. Eight studies compared preferences for GLP1 RA- profile attributes, one compared GLP1 RA versus insulin glargine profiles, and one addressed both comparisons. Important attributes driving patient preferences in DCEs were dose frequency, type of device, needle size, change in glycated hemoglobin, and adverse-event profile. Time trade-off evaluations demonstrated that weekly GLP1 RA injection-device attributes (reconstitution, waiting during preparation, needle handling) had a measurable impact on preference. Willingness-to-pay analysis showed that patients were more willing to pay extra for attributes of once-daily liraglutide over twice-weekly exenatide or insulin. Direct preference elicitation in DCEs revealed that patients preferred medication profiles representing GLP1 RAs with less frequent dosing and preferred GLP1 RA profiles over insulin. Process and outcome attributes are important drivers of patient preference for GLP1 RAs. Findings from patient-preference studies can inform clinical decision-making and help align care with patient values, which has the potential to improve medication adherence and outcomes.
Willingness to Pay for Renewable Energy in Myanmar: Energy Source Preference
The increased use of renewable energy is imperative as a countermeasure to climate change. As with conventional electricity generation technologies, public acceptance of renewables is an important issue, and willingness to pay (WTP) is a widely used indicator to assess such public attitudes. Unfortunately, the literature to date mostly covers developed countries, with few WTP surveys in developing countries. Tackling climate change is an urgent issue for these developing countries; therefore, understanding of public attitudes toward renewables in developing countries is crucial. This study conducted the first survey on WTP for introducing renewable energy in Myanmar. Although Myanmar boasts abundant renewable energy resources, including solar power and biomass in addition to large-scale hydro plants, its resources are not being properly utilized to generate electricity. This study surveyed WTP for power generation by solar photovoltaics, small hydropower, and biomass facilities. The results showed the highest WTP for solar power (USD 1.92) with 10% share in the energy mix, and lower WTP for biomass and small hydropower electricity generations (USD 1.13 and USD 1.17, respectively). Careful public communication is thus crucial for expanding biomass and small-scale hydro power plants.
Factors Driving Patient Preferences for Growth Hormone Deficiency (GHD) Injection Regimen and Injection Device Features: A Discrete Choice Experiment
The daily injection burden of recombinant human growth hormone (r-hGH) replacement therapy to treat growth hormone deficiency (GHD) may reduce compliance and limit treatment benefit. Research is needed to evaluate patient preferences for GHD injection regimen and device features. Quantitatively evaluate factors driving preferences for r-hGH injection regimen and device features among pediatric (3-17 years, and caregivers) and adult (≥25 years) patients with GHD using a discrete choice experiment (DCE) approach. The DCE was part of a broader, cross-sectional observational field study to develop clinical outcome assessments (COAs) that assess the experience of patients taking r-hGH injections. Following ethics approval, discrete choice data were collected through an online questionnaire from consented participants recruited from eight sites in the United States. Participants were presented with 20 choice tasks, each comprising different combinations of two profiles. Participants were then shown the same set of three hypothetical device and injection profiles (ie, storage, preparation, injection type device, maintenance, dose setting, injection schedule) and asked whether they would choose each profile over their current device and schedule. Choice-based conjoint analyses were used to estimate the marginal utilities and values for treatment attributes. Subject preferences were estimated at individual and aggregate levels. Two hundred and twenty-four participants completed the DCE (n=75 adults, n=79 adolescent/caregiver dyads, n=70 child/caregiver dyads). Injection schedule was the strongest predictor of choice for the total sample and each patient group. Less frequent injection schedules were more likely to be chosen by participants. A \"ready to use\" injection was preferred, with no preference for auto-injector versus needle-free device. Most participants would choose the hypothetical injection devices and less frequent dosing over their current daily administered device schedule. Patients prefer a less frequent injection regimen for treating GHD. Addressing patient preferences may improve compliance, adherence, and ultimately, clinical outcomes.
Who Would Pay Higher Taxes for Better Mental Health? Results of a Large-Sample National Choice Experiment
Policy Points  Public funding for mental health programs must compete with other funding priorities in limited state budgets.  Valuing state‐funded mental health programs in a policy‐relevant context requires consideration of how much benefit from other programs the public is willing to forgo to increase mental health program benefits and how much the public is willing to be taxed for such program benefits.  Taxpayer resistance to increased taxes to pay for publicly funded mental health programs and perceived benefits of such programs vary with state population size.  In all states, taxpayers seem to support increased public funding for mental health programs such as state Medicaid services, suggesting such programs are underfunded from the perspective of the average taxpayer. Context The direct and indirect impacts of serious mental illness (SMI) on health care systems and communities represents a significant burden. However, the value that community members place on alleviating this burden is not known, and SMI treatment must compete with a long list of other publicly funded priorities. This study defines the value of public mental health interventions as what the public would accept, either in the form of higher taxes or in reductions in nonhealth programs, in return for increases in the number of mental health program beneficiaries. Methods We developed and fielded a best‐practice discrete‐choice experiment survey to quantify respondents’ willingness to be taxed for increased spending among several competing programs, including a program for treating severe mental health conditions. A realistic decision frame was used to elicit respondents’ willingness to support expanded state budgets for mental health programs if that expansion required either cuts in the competing publicly financed programs or tax increases. The survey was administered to a general population national sample of 10,000 respondents. Findings Nearly half the respondents in our sample either chose “no budget increase” for all budget scenarios or had preferences that were too disordered to estimate trade‐off values. Including zero values for those respondents, we found that the mean (median) amount that all respondents were willing to be taxed annually for public mental health programs ranged between$156 ($ 99) per year for large‐population states and$343 ($ 181) per year for small‐population states. Respondents would accept reductions of between 1.6 and 3.4 beneficiaries in other programs in return for 1 additional mental health program beneficiary. Conclusions Our results are consistent with findings that a substantial portion of the US public is unwilling to pay higher taxes. Nevertheless, even including the substantial number of respondents who opposed any tax increase, the willingness of both the mean and median respondent to be taxed for mental health program expansions implies that programs providing mental health services such as state Medicaid are underfunded.
Quantifying Preferences for CAR‐T Compared to Standard of Care as a First‐Line Treatment Among Patients With Multiple Myeloma
Background CAR‐T therapy is approved for the treatment of relapsed refractory multiple myeloma (MM) and is being studied for newly diagnosed MM (NDMM). The use of novel therapies in early‐line MM raises questions on the acceptability of upfront risks in exchange for extended relapse‐free periods without the treatment burden and limitations on daily activities associated with maintenance therapy. Methods A discrete‐choice experiment was designed to elicit adults' preferences for hypothetical NDMM treatments. Benefits included time to relapse and reduction of treatment impact on daily activities. Severe adverse events were included to better understand patient preferences for rare but significant events. Results On average, extending the time to relapse from 3 years (with moderate limitations on daily activities) to 5 years (without limitations) was three times more important than avoiding a 20% risk of hospitalization due to severe ICANS/CRS. Analysis revealed three latent preference classes: a benefit–risk trading class (65%), a class (28%) unwilling to accept increases in short‐term treatment‐related mortality, and a class (7%) that provided statistically uninformative data. For the trading class, for two additional relapse‐free years with minor limitations, all else equal, patients would accept up to a 30% risk of severe ICANS/CRS‐related hospitalization along with 0% risk of treatment‐related mortality. Alternatively, they would accept up to an 8% risk of treatment‐related mortality with a 0% risk of severe ICANS/CRS‐related hospitalization, or various combinations of lower AE risks. Conclusion These results reveal preference heterogeneity among MM patients and the importance of effective communication about the benefits and risks of novel therapies.
Preferences of patients and physicians in the United States for relapsed/refractory follicular lymphoma treatments
Background Patients with follicular lymphoma (FL) often relapse or become refractory to treatment (R/R). While the R/R FL treatment landscape evolves, little is known about the priorities of patients and physicians. This discrete‐choice experiment (DCE) study assessed patients' and physicians' treatment preferences, and the trade‐offs they would be willing to make between efficacy, tolerability, and administration. Methods An online survey was conducted in US‐based patients (≥18 years) with R/R FL and FL‐treating physicians. The DCE was informed by a targeted literature review, clinical data, expert oncologist input, and pilot interviews. Participants completed eight experimental choice tasks where they chose between two hypothetical treatment profiles defined by six attributes: progression‐free survival (PFS), administration/monitoring, risks of laboratory abnormalities requiring intervention, severe infections, diarrhea, and cytokine release syndrome (CRS). Relative attribute importance (RAI) and willingness to trade‐off between PFS and other attributes were estimated. Results Two‐hundred patients (mean age 63.5 years; median three prior lines of therapy) and 151 FL‐treating physicians participated. Increasing PFS was most important for both groups, although it was relatively less important to patients than physicians (RAI 35.2% vs. 45.7%). Administration/monitoring was three times more important to patients than physicians (RAI 28.8% vs. 9.5%); patients preferred oral treatment and would be willing to tolerate a significant reduction in PFS for oral administration over weekly intravenous infusions. Avoiding CRS was less important to patients than to physicians (RAI 7.7% vs. 15.8%). Both groups would accept shorter PFS for reduced risks of side effects (especially of laboratory abnormalities for patients and of CRS for physicians). Conclusion Although PFS was the most important attribute to patients and physicians, both would tolerate lower PFS for reduced side effects. Patients would also accept a substantial reduction in PFS for oral administration. Differences between the preferences/priorities of patients and physicians highlight the importance of shared decision‐making.
Feasibility of a best–worst scaling exercise to set priorities for autism research
Background The preferences of autism stakeholders regarding the top priorities for future autism research are largely unknown. Objective This study had two objectives: First, to examine what autism stakeholders think new research investments should be and the attributes of investment that they consider important, and second, to explore the feasibility, acceptability and outcomes of two prioritization exercises among autism stakeholders regarding their priorities for future research in autism. Design This was  a prospective stakeholder‐engaged iterative study consisting of best–worst scaling (BWS) and direct prioritization exercise. Setting and Participants A national snowball sample of 219 stakeholders was included: adults with autism, caregivers, service providers and researchers. Main Outcome Measures The main outcomes measures were attributes that participants value in future research investments, and priority research investments for future research. Results Two hundred and nineteen participants completed the exercises, of whom 11% were adults with autism, 58% were parents/family members, 37% were service providers and 21% were researchers. Among stakeholders, the BWS exercises were easier to understand than the direct prioritization, less frequently skipped and yielded more consistent results. The proportion of children with autism affected by the research was the most important attribute for all types of stakeholders. The top three priorities among future research investments were (1) evidence on which child, family and intervention characteristics lead to the best/worst outcomes; (2) evidence on how changes in one area of a child's life are related to changes in other areas; and (3) evidence on dietary interventions. Priorities were similar for all stakeholder types. Conclusions The values and priorities examined here provide a road map for investigators and funders to pursue autism research that matters to stakeholders. Patient or Public Contribution Stakeholders completed a BWS and direct prioritization exercise to inform us about their priorities for future autism research.
Preference for Immunotherapy with Tablets by People with Allergic Rhinitis
People with allergic rhinitis (AR) who are not controlled on conventional therapy can be treated using allergy immunotherapy (AIT) administered as tablets, injections or drops. In the US, the use of sublingual immunotherapy as tablets (SLIT-tablets) is limited in comparison to subcutaneous immunotherapy (SCIT). This study investigated patients' preference for SLIT-tablets vs monthly or weekly SCIT from a US patient perspective. We carried out a discrete choice experiment (DCE) consisting of two blocks with eight choice sets. Adults and caregivers of children with moderate-to-severe AR were included if they had not previously or were not currently receiving AIT. Three attributes were included in the design: the mode and frequency of administration, the risk of systemic reactions and the co-payment. A total of 724 adults with AR and 665 caregivers of children with AR were included in the study. Both adults and caregivers had a significant preference for SLIT-tablets compared with both weekly and monthly injections and for less risk of anaphylactic shock. Caregivers were more risk-averse than adults when choosing their treatment, and the younger the child, the more risk-averse the caregiver. The preference for SLIT-tablets was found for both monoallergic and polyallergic adults and caregivers of monoallergic and polyallergic children. Respondents not wanting AIT for free were more risk-averse than those indicating that they wanted AIT for free. Our findings suggest that SLIT-tablets is the preferred route of administration for AIT among adults and caregivers of children with AR.
Public preferences regarding data linkage for research: a discrete choice experiment comparing Scotland and Sweden
Background There are increasing examples of linking data on healthcare resource use and patient outcomes from different sectors of health and social care systems. Linked data are generally anonymised, meaning in most jurisdictions there are no legal restrictions to their use in research conducted by public or private organisations. Secondary use of anonymised linked data is contentious in some jurisdictions but other jurisdictions are known for their use of linked data. The publics’ perceptions of the acceptability of using linked data is likely to depend on a number of factors. This study aimed to quantify the preferences of the public to understand the factors that affected views about types of linked data and its use in two jurisdictions. Method An online discrete choice experiment (DCE) previously conducted in Scotland was adapted and replicated in Sweden. The DCE was designed, comprising five attributes, to elicit the preferences from a representative sample of the public in both jurisdictions. The five attributes (number of levels) were: type of researcher using linked data (four); type of data being linked (four); purpose of the research (three); use of profit from using linked data (four); who oversees the research (four). Each DCE contained 6 choice-sets asking respondents to select their preferred option from two scenarios or state neither were acceptable. Background questions included socio-demographics. DCE data were analysed using conditional and heteroskedastic conditional logit models to create forecasts of acceptability. Results The study sample comprised members of the public living in Scotland ( n  = 1004) and Sweden ( n  = 974). All five attributes were important in driving respondents’ choices. Swedish and Scottish preferences were mostly homogenous with the exception of ‘who oversees the research using linked data’, which had relatively less impact on the choices observed from Scotland. For a defined ‘typical’ linked data scenario, the probability (on average) of acceptance was 85.7% in Sweden and 82.4% in Scotland. Conclusion This study suggests that the public living in Scotland and Sweden are open to using anonymised linked data in certain scenarios for research purposes but some caution is advisable if the anonymised linked data joins health to non-health data.
For more than money: willingness of health professionals to stay in remote Senegal
Background Poor distribution of already inadequate numbers of health professionals seriously constrains equitable access to health services in low- and middle-income countries. The Senegalese Government is currently developing policy to encourage health professionals to remain in areas defined as ‘difficult’. Understanding health professional’s preferences is crucial for this policy development. Methods Working with the Senegalese Government, a choice experiment (CE) was developed to elicit the job preferences of physicians and non-physicians. Attributes were defined using a novel mixed-methods approach, combining interviews and best-worst scaling (Case 1). Six attributes were categorised as ‘individual (extrinsic) incentive’ attributes (‘type of contract’, ‘provision of training opportunities’, ‘provision of an allowance’ and ‘provision of accommodation’) or ‘functioning health system’ attributes (‘availability of basic equipment in health facilities’ and ‘provision of supportive supervision by health administrators’). Using face-to-face interviews, the CE was administered to 55 physicians (3909 observations) and 246 non-physicians (17 961 observations) randomly selected from those working in eight ‘difficult’ regions in Senegal. Conditional logit was used to analyse responses. This is the first CE to both explore the impact of contract type on rural retention and to estimate value of attributes in terms of willingness to stay (WTS) in current rural post. Results For both physicians and non-physicians, a permanent contract is the most important determinant of rural job retention, followed by availability of equipment and provision of training opportunities. Retention probabilities suggest that policy reform affecting only a single attribute is unlikely to encourage health professionals to remain in ‘difficult’ regions. The relative importance of an allowance is low; however, the level of such financial incentives requires further investigation. Conclusion Contract type is a key factor impacting on retention. This has led the Senegalese Health Ministry to introduce a new rural assignment policy that recruits permanent staff from the pool of annually contracted healthcare professionals on the condition that they take up rural posts. While this is a useful policy development, further efforts to retain rural health workers, considering both personal incentives and the functioning of health systems, are necessary to ensure health worker numbers are adequate to meet the needs of rural communities.
