It is not always about gains: utilities and disutilities associated with treatment features in patients with moderate-to-severe psoriasis

The importance of understanding patient and physician preferences for psoriasis treatment characteristics: a systematic review of discrete-choice experiments

Introduction: Treatment adherence continues to be a major challenge in psoriasis. Patient preference studies, especially discrete-choice experiments, are gaining popularity to gather insights into patient reported treatment outcomes. This systematic literature review aimed to critically assess all discrete choice experiments exploring patients' and physicians' preferences for psoriasis treatment characteristics.Methods: PubMed and EMBASE databases were searched using keywords "psoriasis" and "preferences" to identify relevant literature. Discrete-choice experiments conducted in French or English from the year 2000 onwards, that focused on evaluating psoriasis treatment preferences in patients and/or physicians, were included. The relative importance of treatment attributes was assessed and studies were critically appraised using validated checklists.Results: Out of 987 articles identified, 25 articles fulfilled the inclusion criteria. Overall, patients and physicians prioritize efficacy-specific outcomes. Patients are shown to place greater importance to process attributes when compared to physicians, especially route and location of administration. Physicians focus primarily of efficacy attributes, however when the top two attributes are considered, safety outcomes increasingly become considered important. Of the studies, 60% conducted subgroup analysis, of which many reported associations between specific patient characteristics and preferences. Factors such as age, disease severity, and duration of condition significantly affected preferences for treatment attributes.Conclusions: This review provides insight into the types of attributes that patients and physicians value most, and therefore can help improve shared decision-making. The findings of this study also encourage regulatory agencies to continue integrating patient preferences in their decision-making.

Toward improving respectful maternity care: a discrete choice experiment with rural women in northeast Nigeria

Introduction

There is a limited understanding of the importance of respectful maternity care on utilisation of maternal and newborn health services. This study aimed to determine how specific hypothetical facility birth experience of care attributes influenced rural Nigerian women’s stated preferences for hypothetical place of delivery.

Methods

Attributes were identified through a comprehensive review of the literature. These attributes and their respective levels were further investigated in a qualitative study. We then developed and implemented a cross-sectional discrete choice experiment with a random sample of 426 women who had facility-based childbirth to elicit their stated preferences for facility birth experience of care attributes. Women were asked to choose between two hypothetical health facilities or home birth for future delivery. Choice data were analysed using multinomial logit and mixed multinomial logit models.

Results

Complete data for the discrete choice experiment were available for 425 of 426 women. The majority belonged to Fulani ethnic group (60%) and were married (95%). Almost half (45%) had no formal education. Parameter estimates were all of expected signs suggesting internal validity. The most important influence on choice of place of delivery was good health system condition, followed by absence of sexual abuse, then absence of physical and verbal abuse. Poor facility culture, including an unclean birth environment with no privacy and unclear user fee, was associated with the most disutility and had the most negative impact on preferences for facility-based childbirth.

Conclusion

The likelihood of poor facility birth experiences had a significant impact on stated preferences for place of delivery among rural women in northeast Nigeria. The study findings further underline the important relationship between facility birth experience and utilisation. Achieving universal health coverage would require efforts toward addressing poor facility birth experiences and promoting respectful maternity care, to ensure women want to access the services available.

Shared Decision Making in Psoriasis: A Systematic Review of Quantitative and Qualitative Studies

BACKGROUND

Patients with psoriasis face numerous treatment and self-management decisions. Shared decision making is a novel approach where patients' preferences and values are considered in cooperation with healthcare professionals before making treatment decisions.

OBJECTIVE

The objective of this systematic review was to explore what is illuminated in psoriasis research regarding shared decision making, and to estimate the effects of shared decision-making interventions in this context.

METHODS

Qualitative, quantitative, and mixed-methods studies were eligible for inclusion. We searched six electronic databases up to January 2018. Two reviewers independently applied inclusion and quality criteria. The SPIDER framework was used to identify eligibility criteria for study inclusion. Narrative and thematic syntheses were utilized to identify prominent themes emerging from the data.

RESULTS

A total of 23 studies were included in the review. Of these, we included 18 studies (19 papers) to describe what was illuminated with regard to shared decision making in psoriasis research. Four major themes emerged: interpersonal communication; exchange of competence and knowledge; different world view; and involvement and preference, organized under two analytical themes; "Co-creation of decisions" and "Organization of treatment and treatment needs". For shared decision-making effects, we included four controlled studies. These varied in scope and interventional length and showed limited use of shared decision making-specific outcome measures, reflecting the early stage of the literature. Because of study heterogeneity, a meta-synthesis was not justified.

CONCLUSIONS

There appears to be a need to strengthen the relationship between medical doctors and patients with psoriasis. The evident lack of knowledge about each other's competence and the lack of self-efficacy for both patients and providers challenges the basic principles of shared decision making. The effects of shared decision making in psoriasis are inconclusive, and more research appears necessary to determine the possible benefits of shared decision-making interventions.

Relative Importance of Mode of Administration in Treatment Preferences among Plaque Psoriasis Patients in the United States

Background: Some aspects of psoriasis treatments can negatively influence patients' quality of life. There is evidence from previous preference-elicitation research in psoriasis that administration characteristics are at least as important as treatment outcomes to patients. Objectives: Our objective was to test the hypothesis that patients' preferences for reduced disease and treatment burden are as important as preferences around treatment efficacy. We evaluated patient preferences for attributes of psoriasis treatments, including efficacy, tolerability, and mode and frequency of administration. Methods: Adult patients in the United States with a self-reported physician diagnosis of psoriasis completed an online discrete-choice experiment survey. The survey included eight choice questions, each asking respondents to choose between pairs of hypothetical psoriasis medications defined by attributes including efficacy, adverse reactions, and mode and frequency of administration. A random-parameters logit regression model was used to model the preference data. Results from this model were used to calculate respondents' willingness to trade efficacy for reduced treatment burden. Results: A total of 397 respondents, with a mean self-assessed Psoriasis Activity and Severity Index score of 8.2 (SD, 9.8), provided data for analysis. Improvements in treatment efficacy were more important than improvements in speed of onset and were more important than most increases in the chance of treatment side effects. The maximum possible improvement in treatment efficacy offered in the study was not enough to match the improvements in well being associated with some changes in mode of administration. For example, respondents were willing to accept a reduction in the percentage of patients who achieve clear or almost-clear skin after treatment from approximately 70% to 40% to avoid injections at home and use a topical treatment. Topical treatments were the most preferred option of administration followed by oral agents and intravenous infusion. Conclusions: Psoriasis patients had well-defined preferences for changes in the treatment attributes considered. Avoiding injections in favor of oral or topical treatment was more important to patients than some improvements in efficacy. These findings support previous research regarding the importance of treatment burden relative to outcomes in psoriasis and emphasize the importance of individual patient preferences in determining treatment strategy.

Adherence, satisfaction and preferences for treatment in patients with psoriasis in the European Union: a systematic review of the literature

BACKGROUND AND OBJECTIVE

Adherence to treatment in patients with psoriasis is often poor. An investigation of patient preferences and satisfaction with treatment may be important, based on the expected correlation with therapy compliance. This paper aims to examine and describe the current literature on patient preferences, satisfaction and adherence to treatment for psoriasis in the European Union (EU).

METHODS

Electronic searches were conducted using PubMed, ISI Web of Knowledge, Scopus, Spanish databases and Google Scholar. European studies published in English or Spanish between January 1, 2009 and December 31, 2014 regarding patient-reported outcomes in psoriatic patients were included. Studies conducted in non-EU countries, letters to the editor, editorials, experts' opinions, case studies, congress proceedings, publications that did not differentiate between patients with psoriasis and psoriatic arthritis or studies related to specific treatment were excluded.

RESULTS

A total of 1,769 titles were identified, of which 1,636 were excluded as they were duplicates or did not provide any relevant information. After a full-text reading and application of the inclusion/exclusion criteria, 46 publications were included. This paper will describe publications on adherence (n=4), preferences (n=5) and satisfaction with treatment (n=7). Results related to health-related quality of life articles (n=30) have been published elsewhere. Adherence rates are generally low in psoriasis patients regardless of the type of treatment, severity of disease or methods used to measure adherence. Biologic therapy is associated with greater clinical improvement. There is a direct association between physician recommendations, patient preferences and several domains of treatment satisfaction.

CONCLUSION

The results of this review support the conclusion that adherence rates in patients with psoriasis are suboptimal and highlight the need to improve patient compliance and satisfaction with treatment. Patients' preferences should be taken into account in the treatment decision-making process in order to improve patients' clinical outcomes by ensuring satisfaction and adherence.

A patient-centred approach to biological treatment decision making for psoriasis: an expert consensus

Background

Each individual psoriasis patient has different expectations and goals for biological treatment, which may differ from those of the clinician. As such, a patient‐centred approach to treatment goals remains an unmet need in psoriasis.

Objective

The aim of this study was to review available data on patients’ and physicians’ decision criteria and expectations of biological treatment for moderate‐to‐severe psoriasis with the aim of developing a core set of questions for clinicians to ask patients routinely to understand what is important to them and thus better align physicians’ and patients’ expectations of treatment with biologics and its outcomes.

Methods

A literature search was conducted to identify key themes and data gaps. Aspects of treatment relevant when choosing a biological agent for an individual patient were identified and compared to an existing validated instrument. A series of questions aimed at helping the physician to identify the particular aspects of treatment that are recognised as important to individual psoriasis patients was developed.

Results

Key findings of the literature search were grouped under themes of adherence, decision‐making, quality of life, patient/physician goals, communication, patient‐reported outcomes, satisfaction and patient benefit index. Several aspects of treatment were identified as being relevant when choosing a biological agent for an individual patient.

The questionnaire is devised in two parts. The first part asks questions about patients’ experience of psoriasis and satisfaction with previous treatments. The second part aims to identify the treatment attributes patients consider to be important and may as such affect their preference for a particular biological treatment. The questionnaire results will allow the physician to understand the key factors that can be influenced by biological drug choice that are of importance to the patient. This information can be used be the physician in clinical decision making.

Conclusion

The questionnaire has been developed to provide a new tool to better understand and align patients’ and physicians’ preferences and goals for biological treatment of psoriasis.

Audiologists' preferences for patient-centredness: a cross-sectional questionnaire study of cross-cultural differences and similarities among professionals in Portugal, India and Iran

OBJECTIVE

Patient-centredness has become an important aspect of health service delivery; however, there are a limited number of studies that focus on this concept in the domain of hearing healthcare. The objective of this study was to examine and compare audiologists' preferences for patient-centredness in Portugal, India and Iran.

DESIGN

The study used a cross-sectional survey design with audiologists recruited from three different countries.

PARTICIPANTS

A total of 191 fully-completed responses were included in the analysis (55 from Portugal, 78 from India and 58 from Iran).

MAIN OUTCOME MEASURE

The Patient-Practitioner Orientation Scale (PPOS).

RESULTS

PPOS mean scores suggest that audiologists have a preference for patient-centredness (ie, mean of 3.6 in a 5-point scale). However, marked differences were observed between specific PPOS items suggesting these preferences vary across clinical situations. A significant level of difference (p<0.001) was found between audiologists' preferences for patient-centredness in three countries. Audiologists in Portugal had a greater preference for patient-centredness when compared to audiologists in India and Iran, although no significant differences were found in terms of age and duration of experience among these sample populations.

CONCLUSIONS

There are differences and similarities in audiologists' preferences for patient-centredness among countries. These findings may have implications for the training of professionals and also for clinical practice in terms of optimising hearing healthcare across countries.

A psychophysical account of patient non-adherence to medical prescriptions. The case of insulin dose adjustment

AIM

Diabetic patients often do not adjust their insulin doses using the algorithms that they have been taught. While this behavior may intuitively have a number of causes, such as the complexity of the decision or the fear of hypoglycaemia, we propose in this article a more general, "psychophysical", explanation based on behavioral economics concepts used to describe decisions made under uncertainty and risk. The concepts discussed herein may not be familiar to clinicians, who will find here an introduction to theories that may be helpful in understanding some aspects of non-adherence to medical prescriptions.

RESULTS

1) The Prospect Theory of Kahneman and Tversky proposes that choices made in the context of risk are subject to loss aversion. 2) Decisions under uncertainty use mental short cuts called "heuristics", which can lead to biases; for instance, overestimating the probability of the risk. 3) To understand the very concept of risk, emotions must be considered with a special focus on anticipated regret. 4) Finally, selection difficulty is an important determinant of the preference for the status quo.

CONCLUSION

These concepts may be relevant for understanding a preference for the status quo in decisions made in a context of uncertainty and risk, such as insulin dose adjustment. We suggest that these mental mechanisms may also be involved in other aspects of patients' non-adherence. As other common human behaviors, non-adherence may actually often be a consequence of biases resulting from our ways of thinking, being both cognitive and emotional, and, according to Kahneman, more often "fast" than "slow". Empirical studies are needed to support this hypothesis.
