Adult, adolescent, and caregiver preferences for attributes of topical treatments for mild-to-moderate atopic dermatitis: a discrete-choice experiment.

Purpose: Topical treatments for mild-to-moderate (MM) atopic dermatitis (AD) include emollients, corticosteroids, calcineurin inhibitors, a Janus kinase inhibitor, and a phosphodiesterase 4 inhibitor, which differ in multiple ways. This study aimed to quantify the conditional relative importance (CRI) of attributes of topical treatments for MM AD among adult and adolescent patients and caregivers of children with MM AD.Materials and methods: A discrete-choice experiment (DCE) survey was administered to US adults and adolescents with MM AD and caregivers of children with MM AD. Each choice task comprised 2 hypothetical topical treatments characterized by efficacy, adverse events, vehicle, and application frequency. Data were analyzed using a random-parameters logit model to calculate the CRI of each attribute.Results and conclusions: 300 adults, 331 adolescents, and 330 caregivers completed the DCE. Avoiding changes in skin color (CRI 29.0) and time until itch improves (26.6) were most important to adults, followed by time until clear/almost clear skin (17.8). Application frequency (3.0) did not have a statistically significant impact on adults' choices. Adolescents were less concerned about changes in skin color than adults or caregivers; caregivers were less concerned about time until clear/almost clear skin than patients. Physicians should consider age-relevant aspects of preferences in treatment discussions with patients and caregivers.

Patient and caregiver preferences for haemophilia treatments: A discrete-choice experiment.

INTRODUCTION: An evolving haemophilia treatment landscape provides new possibilities for previously unattainable lifestyles. AIM: We sought to understand how people with haemophilia (PwH) and their caregivers value the potential benefits of novel prophylactic treatments. We conducted a discrete-choice experiment (DCE) to quantify preferences for features of haemophilia treatments among adults and caregivers of children with haemophilia. A best-worst scaling (BWS) exercise measured the perceived burden of treatment administration features. METHODS: A cross-sectional, web-based survey was administered to male adults (≥18 years) and caregivers of male children (≤17 years) living with haemophilia in the United States. Respondents evaluated eight pairs of hypothetical haemophilia treatment profiles defined by six attributes in the DCE and 15 features in the BWS. RESULTS: In the DCE, both adults with haemophilia (n = 151) and caregivers (n = 151) prioritised avoiding the risk of developing inhibitor/ anti-drug antibodies and treatments that allowed for a more active life. They placed a lower priority on reducing the number of spontaneous bleeding episodes, route and frequency of administration, and avoiding the risk of hospitalisation due to adverse events. The BWS documented the burdensomeness of IV infusions and medications that require mixing and refrigeration. CONCLUSION: PwH and caregivers prefer treatments that enable a more active lifestyle with a lower risk of inhibitor development. Both groups valued the ability to lead an active life over reducing spontaneous bleeding, with caregivers placing the most weight on this attribute. As new treatments expand possibilities, healthcare professionals and PwH should continue to share decision-making, incorporating clinical judgment and individual preferences.

Patients' Preferences for Adjunctive Parkinson's Disease Treatments: A Discrete-Choice Experiment.

Background: Several adjunctive medications are available to reduce OFF time between levodopa/carbidopa (LD/CD) doses for people with Parkinson's disease (PD). Objective: To explore how individuals with PD balance benefits and burdens when considering adjunctive medications. Methods: US adults (30-83 years) with self-reported PD, currently treated with LD/CD, who experienced OFF episodes were recruited through the Fox Insight study to complete a discrete-choice experiment survey. Respondents selected among experimentally designed profiles for hypothetical adjunctive PD treatments that varied in efficacy (additional ON time), potential adverse effects (troublesome dyskinesia, risk of diarrhea, risk of change in bodily fluid color), and dosing frequency or the option "No additional medicine". Data were analyzed with random-parameters logit models. Results: Respondents (N=480) would require ≥60 additional minutes of daily ON time to accept either a 40% risk of change in bodily fluid color or 10 additional minutes with troublesome dyskinesia daily. Respondents would require 40 additional minutes of daily ON time to accept a 10% risk of diarrhea and 22 additional minutes of daily ON time to switch from 1 additional pill each day to 1 pill with each LD/CD dose. On average, respondents preferred adjunctive PD medication over no additional medication. Results predicted that 59.1% of respondents would select a hypothetical treatment profile similar to opicapone, followed by no additional medication (27.5%) and a hypothetical treatment profile similar to entacapone (13.4%). Limitations: The data collected were based on responses to hypothetical choice profiles in the survey questions. The attributes and levels selected for this study were intended to reflect the characteristics of opicapone and entacapone; attributes associated with other adjunctive therapies were not evaluated. Conclusion: Patients with PD expressed interest in adjunctive treatment to increase ON time and would accept reduced ON time to avoid adverse effects.

A discrete-choice experiment study of physicians' prioritization of attributes of medical treatments for endometriosis-associated pain.

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.

Experiences and Treatment Preferences in Patients With Psoriatic Arthritis: A Cross-Sectional Study in the ArthritisPower Registry.

INTRODUCTION: Despite recent advances in treatment for psoriatic arthritis (PsA), many patients experience inadequate response or intolerance to therapy, indicating that unmet treatment-related needs remain. To further characterize these unmet needs, we evaluated patients' experiences regarding the burden of PsA symptoms and disease impacts, and patients' preferences for treatment. METHODS: Patients from ArthritisPower, a rheumatology research registry, completed a web-based survey. Object case best-worst scaling (BWS) was used to evaluate the relative burden of 11 PsA-related symptoms and the relative importance of improvement in nine PsA-related disease impacts. BWS data were analyzed using a random-parameters logit model. Patient demographics, preferences for mode and frequency of therapy, and preferences for methotrexate were analyzed descriptively. RESULTS: Among the 332 participants, most were White (94%), female (80%), with mean age of 54 years (SD 11.4). In the BWS, joint pain was the most bothersome symptom, followed by other musculoskeletal pain and fatigue. The BWS for disease impacts found that improvements in the ability to perform physical activities were most important, followed by improvements in the ability to function independently, sleep quality, and the ability to perform daily activities. The most burdensome symptoms and desired disease impact improvements were similar in patients regardless of their experience with biologic disease-modifying antirheumatic drugs. The most preferred mode and frequency of treatment administration was oral, once-daily medication (preferred by 38% of respondents), and 74% prioritized therapies that significantly improved joint-related symptoms versus psoriasis-related symptoms. The majority of respondents (65%) preferred PsA treatment regimens that did not include methotrexate. CONCLUSIONS: Patients with PsA from a rheumatology registry found musculoskeletal pain symptoms to be the most bothersome and prioritized improvements to functional impacts of their disease. These findings can better inform development of new therapies and guide shared patient-provider treatment decision-making.

Exploring Decisional Conflict With Measures of Numeracy and Optimism in a Stated Preference Survey.

OBJECTIVES: Low optimism and low numeracy are associated with difficulty or lack of participation in making treatment-related health care decisions. We investigated whether low optimism and low self-reported numeracy scores could help uncover evidence of decisional conflict in a discrete-choice experiment (DCE). METHODS: Preferences for a treatment to delay type 1 diabetes were elicited using a DCE among 1501 parents in the United States. Respondents chose between two hypothetical treatments or they could choose no treatment (opt out) in a series of choice questions. The survey included a measure of optimism and a measure of subjective numeracy. We used latent class analyses where membership probability was predicted by optimism and numeracy scores. RESULTS: Respondents with lower optimism scores had a higher probability of membership in a class with disordered preferences (P value for optimism coefficient = 0.032). Those with lower self-reported numeracy scores were more likely to be in a class with a strong preference for opting out and disordered preferences (P = 0.000) or a class with a preference for opting out and avoiding serious treatment-related risks (P = 0.015). CONCLUSIONS: If respondents with lower optimism and numeracy scores are more likely to choose to opt out or have disordered preferences in a DCE, it may indicate that they have difficulty completing choice tasks.

Patient Preferences for Treating "OFF" Episodes in Parkinson's Disease: A Discrete Choice Experiment.

INTRODUCTION: Several on-demand treatments are available for management of "OFF" episodes in patients with Parkinson's disease (PD). We evaluated patients' preferences for features of theoretical on-demand treatment options. METHODS: In a discrete choice experiment, US adults with self-reported PD of ≥5 years, or <5 years with "OFF" episodes, taking oral carbidopa/levodopa, selected between pairs of theoretical on-demand treatments that varied by mode of administration (with and without mode-specific adverse events [AEs]), time to FULL "ON," duration of "ON," and out-of-pocket cost for a 30-day supply. Data were analyzed with a random parameters logit model; results were used to calculate relative importance of treatment attributes, preference shares, and willingness to pay. RESULTS: Among 300 respondents, 98% had "OFF" episodes. Across the range of attribute levels included in the survey, avoiding $90 cost was most important to respondents, followed by a preferable mode of administration with associated AEs and decreasing time to FULL "ON." Duration of "ON" was relatively less important. On average, respondents preferred a theoretical dissolvable sublingual film versus other theoretical treatments with alternative modes of administration. Respondents were willing to pay $28-$52 US dollars to switch from least- to more-preferred mode of administration with associated AEs, $58 to reach FULL "ON" in 15 versus 60 min, and $9 to increase duration of FULL "ON" from 1 to 2 h. CONCLUSION: Respondents with PD valued lower out-of-pocket cost and a sublingual mode of administration with its associated AEs when choosing an on-demand treatment for "OFF" episodes.
