The Impact of Reproductive Issues on Preferences of Women with Relapsing Multiple Sclerosis for Disease-Modifying Treatments

Decision Making About Disease-Modifying Treatments for Relapsing-Remitting Multiple Sclerosis: Stated Preferences and Real-World Choices

BACKGROUND

People with relapsing-remitting multiple sclerosis can benefit from disease-modifying treatments (DMTs). Several DMTs are available that vary in their efficacy, side-effect profile and mode of administration.

OBJECTIVE

We aimed to measure the preferences of people with relapsing-remitting multiple sclerosis for DMTs using a discrete choice experiment and to assess which stated preference attributes correlate with the attributes of the DMTs they take in the real world.

METHODS

Discrete choice experiment attributes were developed from literature reviews, interviews and focus groups. In a discrete choice experiment, participants were shown two hypothetical DMTs, then chose whether they preferred one of the DMTs or no treatment. A mixed logit model was estimated from responses and individual-level estimates of participants' preferences conditional on their discrete choice experiment choices calculated. Logit models were estimated with stated preferences predicting current real-world on-treatment status, DMT mode of administration and current DMT.

RESULTS

A stated intrinsic preference for taking a DMT was correlated with currently taking a DMT, and stated preferences for mode of administration were correlated with the modes of administration of the DMTs participants were currently taking. Stated preferences for treatment effectiveness and adverse effects were not correlated with real-world behaviour.

CONCLUSIONS

There was variation in which discrete choice experiment attributes correlated with participants' real-world DMT choices. This may indicate patient preferences for treatment efficacy/risk are not adequately taken account of in prescribing. Treatment guidelines must ensure they take into consideration patients' preferences and improve communication around treatment efficacy/risk.

Individual Differences in the Patient Experience of Relapsing Multiple Sclerosis (RMS): A Multi-Country Qualitative Exploration of Drivers of Treatment Preferences Among People Living with RMS

AIMS

The aim of this study was to explore the experiences, values and preferences of people living with relapsing multiple sclerosis (PLwRMS) focusing on their treatments and what drives their treatment preferences.

METHODS

In-depth, semi-structured, qualitative telephone interviews were conducted using a purposive sampling approach with 72 PLwRMS and 12 health care professionals (HCPs, MS specialist neurologists and nurses) from the United Kingdom, United States, Australia and Canada. Concept elicitation questioning was used to elicit PLwRMS' attitudes, beliefs and preferences towards features of disease-modifying treatments. Interviews with HCPs were conducted to inform on HCPs' experiences of treating PLwRMS. Responses were audio recorded and transcribed verbatim and then subjected to thematic analysis.

RESULTS

Participants discussed numerous concepts that were important to them when making treatment decisions. Levels of importance participants placed on each concept, as well as reasons underpinning importance, varied substantially. The concepts with the greatest variability in terms of how much PLwRMS found them to be important in their decision-making process were mode of administration, speed of treatment effect, impact on reproduction and parenthood, impact on work and social life, patient engagement in decision making, and cost of treatment to the participant. Findings also demonstrated high variability in what participants described as their ideal treatment and the most important features a treatment should have. HCP findings provided clinical context for the treatment decision-making process and supported patient findings.

CONCLUSIONS

Building upon previous stated preference research, this study highlighted the importance of qualitative research in understanding what drives patient preferences. Characterized by the heterogeneity of the RMS patient experience, findings indicate the nature of treatment decisions in RMS to be highly individualized, and the subjective relative importance placed on different treatment factors by PLwRMS to vary. Such qualitative patient preference evidence could offer valuable and supplementary insights, alongside quantitative data, to inform decision making related to RMS treatment.

"I'm walking into the unknown": Qualitative insights into how emotions and lived experience related to multiple sclerosis diagnosis impact on decisions to pursue disease modifying treatment

INTRODUCTION

People with Relapsing Remitting Multiple Sclerosis (RRMS) are increasingly included as active participants in shared decision making around their treatment options. Choosing a first disease modifying treatment (DMT) is a complex process that often takes place soon after a diagnosis has been given. Patients therefore are often required to make difficult decisions at a time when they are still coming to terms with their illness. This study investigated the views and experiences of recently diagnosed patients with RRMS when they were making their initial DMT choice.

METHOD

This was a qualitative study involving in-depth semi-structured interviews with patients with RRMS in a National Health Service (NHS) setting in the United Kingdom. Data were collected from 6 patients and analysis was guided by an Interpretive Phenomenological Analysis (IPA) approach.

RESULTS

Initial reactions to diagnosis were characterized by strong emotions and a feeling of despair and hopelessness. Subsequently the DMT decision was shaped by multiple considerations around maintaining normality, and restoring hope and control over one's life whilst reconciling uncertainty around efficacy. Considering the future with a DMT elicited reflections around employment and family planning.

CONCLUSION

Emotions and lived experience related to recent MS diagnosis can impact on the initial DMT decision in number of ways. Health care professionals need to understand the lived experience of patients making DMT decisions soon after diagnosis when engaging in shared decision making.

Incorporating patients' preferences in the value assessment of disease-modifying therapies for multiple sclerosis: a narrative review

Introduction: Despite the increasing role of patients in the US healthcare system, patients have yet been engaged in the value assessment of their treatments, including disease-modifying therapies (DMTs) for multiple sclerosis (MS). The objectives of this review were therefore to summarize existing studies on cost-effectiveness analysis (CEA) with quality-adjusted life years (QALYs) and patients' preferences of DMTs for MS, and to discuss how to incorporate patients' preferences into the value assessment of DMTs.Area covered: We reviewed previous systematic reviews and conducted further search until November 2020 for studies on CEA with QALYs and patients' preferences of DMTs for MS. We identified the outcomes that were assessed or valued in the CEA studies and the DMT attributes that were important to patients with MS.Expert opinion: Our literature review showed that the studies using CEA with QALYs failed to capture some important DMT attributes, e.g., route and frequency of administration, identified in the studies on the patients' preferences. Various approaches were available for incorporating the patients' preferences in the value assessment of DMTs for MS. We supported this incorporation, which subsequently would increase patient access to preferred DMTs.

High-Efficacy Disease-Modifying Therapies in People with Relapsing-Remitting Multiple Sclerosis: The Role of Risk Attitude in Treatment Decisions

BACKGROUND

Risk attitude is defined as the willingness to tolerate risk to achieve a greater expected return. Limited information is available on how relapsing-remitting multiple sclerosis people's perceptions about disease trajectory and risk attitude may influence treatment choices.

METHODS

A non-interventional study applying principles of behavioral economics was conducted to assess willingness to receive unwarranted high-efficacy disease-modifying therapy (DMT) according to best-practice guidelines. People with relapsing-remitting multiple sclerosis (PwRRMS) according to 2010 McDonald criteria completed a survey on symptom severity, risk preferences, and management of simulated case scenarios mimicking the current treatment landscape. PwRRMS's choice for high-efficacy agents was established as the participant's selection of monoclonal antibodies for case scenarios with at least 2 years of clinical and radiological stability.

RESULTS

A total of 211 PwRRMS were studied (mean age 39.1 ± 9.5 years, 70.1% female, mean Expanded Disability Status Scale score 1.8 ± 1.1). Almost 50% (n = 96) opted for a high-efficacy DMT despite the lack of evidence of disease activity. Younger age and risk-seeking behavior were associated with an increased likelihood of selecting unwarranted high-efficacy DMT [odds ratio (OR) 2.00, 95% confidence interval (CI) 1.02-3.93, p = 0.043, and OR 2.17, 95% CI 1.09-4.30, p = 0.027, respectively]. Clinical characteristics or subjective perception of symptom severity had no influence on participants' treatment choices.

CONCLUSION

Identifying PwRRMS with risk-seeking behavior would be crucial to implementing specific educational strategies to manage information on disease prognosis, treatment expectations, and safety risk knowledge.
