Preferences of people with Type 2 diabetes for diabetes care: a discrete choice experiment

The Evolving Landscape of Discrete Choice Experiments in Health Economics: A Systematic Review

INTRODUCTION

Stakeholder preference evaluations are increasingly emphasized in healthcare policy and health technology assessment. Discrete choice experiments (DCEs) are the most common method for quantifying preferences among patients, the public, and healthcare professionals. While prior reviews (1990-2017) have examined DCE trends, no comprehensive synthesis exists for studies published since 2018. This updated review (2018-2023) provides critical insights into evolving methodologies and global trends in health-related DCEs.

METHODS

A systematic search (2018-2023) of Medline, Embase, and Web of Science identified relevant studies. Studies were screened for inclusion and data were extracted, including details on DCE design and analysis. To enable trend comparisons, the search strategy and extraction items aligned with previous reviews.

RESULTS

Of 2663 identified papers, 1279 met the inclusion criteria, reflecting a significant rise in published DCEs over time. DCEs were conducted globally, with a remarkable increase in publications from Asia and Africa compared with previous reviews. Experimental designs and econometric models have advanced, continuing prior trends. Notably, most recent DCEs were administered online.

DISCUSSION

The rapid growth of DCE applications underscores their importance in health research. While the methodology is advancing rapidly, it is crucial that researchers provide full transparency in reporting their methods, particularly in detailing experimental designs and validity tests, which are too often overlooked. Key recommendations include improving reporting of experimental designs, applying validity tests, following good practices for presenting benefit-risk attributes, and adopting open science practices. Ensuring methodological rigor will maximize the impact and reproducibility of DCE research in health economics.

Powerful together with diabetes, a group-based self-management intervention for patients with type 2 diabetes from lower educational groups: study protocol for a hybrid type 2 evaluation

INTRODUCTION

Type 2 diabetes mellitus (T2DM) is a major burden on public health worldwide. To reduce adverse events and complications, effective T2DM self-management is required. Self-management and glycaemic control are generally poorer in lower educated people compared with higher educated people. This study aims to assess the (cost-)effectiveness and to conduct a process evaluation of a diabetes self-management programme, 'Powerful Together With Diabetes' (PTWD), which is specifically developed for patients from lower educational groups.

METHODS AND ANALYSIS

The PTWD programme is focused on attaining basic knowledge and skills for effective diabetes self-management. In a previous study (the Diabetes in Social Context (DISC) study), lower-educated participants enjoyed the PTWD programme as well as improved their T2DM-related behaviours. The design of the study is an effectiveness-implementation hybrid type 2 trial. We will conduct mixed methods effectiveness, process and economic evaluations. To investigate the (cost-)effectiveness, a two-arm quasi-experimental trial will be conducted with a parallel mixed method process evaluation. The primary outcome of the study is change in haemoglobin A1c levels from baseline to 12 months. Secondary outcomes include use of primary and secondary care, medication use, blood biomarkers, T2DM self-management health behaviours, anthropometrics, and quality of life. Data will be collected with questionnaires, physical activity trackers and registration data from general practitioner registries. To see if the results are maintained, we will also measure the outcomes 24 months after baseline. Study participants are patients from lower educational groups living with T2DM between 35 and 70 years old. Participants will be recruited through general practices, and the intervention will be held in community centres. Our aim is to include 114 participants in the intervention group and 570 participants in the control group.

ETHICS AND DISSEMINATION

This study has been approved by the Medical Ethics Committee of the Academic Medical Center in Amsterdam (#2021_222). Participants will sign an informed consent form prior to enrolment. Manuscripts with the results of the effectiveness, economic and process evaluations will be published in peer-reviewed journals.

TRIAL REGISTRATION NUMBER

Preferences of continuous care service options for patients with venous leg ulcer development of attributes for discrete choice experiments

BACKGROUND

Patients suffering from lower extremity venous ulcers typically undergo prolonged dressing changes, entailing extended treatment cycles and significant costs, creating an urgent need for effective continuous care. There is scarce literature reporting on the preferences and requirements for wound care within continuous care services for such conditions. Discrete choice experiments serve as an innovative method to elicit patient preferences, where the development of attributes and levels is a critically important process.

OBJECTIVE

To identify attributes and levels patients with venous leg ulcers consider when making decisions about continued care services for venous leg ulcers.

METHODS

In this study, we employed four steps to devise service features (i.e., attributes) and their potential manifestations (i.e., levels). Firstly, we conducted a systematic literature search with articles screened and content compiled by two researchers to identify possible service attributes. Secondly, we conducted in-depth interviews with patients suffering from venous leg ulcers to gather personal experiences and expectations for quality care, and used Nvivo11.0 for data management. Thirdly, focus group discussions were held to assess general viewpoints from various perspectives. Finally, expert meetings were organized to refine our research tools further. To narrow down the attributes to a manageable number for the discrete choice experiment, focus groups and expert meetings performed ranking exercises, calculating the average importance scores by dividing the total score by the number of participants and ranking attributes from highest to lowest average scores.

RESULTS

Through literature reviews, qualitative data acquisition, expert meetings, and ranking exercises, a total of six attributes were finalized, each with two to three levels. The attributes included: 1) service cost (Ave score: 4.7); 2) Mode of service delivery (Ave score: 4.5); 3) Service type (Ave score: 4.4); 4) Consistency of caregiver (Ave score: 4.4); 5) Category of service providers (Ave score: 4.3); and 6) Appointment scheduling (Ave score: 4.3). These attributes encompassed key aspects related to wound care in the continuous care services for patients with venous leg ulcers.

CONCLUSIONS

The mixed-methods approach adopted in this study has proven particularly suitable for identifying, refining, and selecting attributes and levels for discrete choice experiments. By leveraging the advantages and limitations of the four steps, and especially through qualitative data analysis, a more profound and comprehensive understanding of the attributes and levels was achieved. This approach has facilitated the practicality and accuracy in attribute construction, enhancing the overall efficacy of the DCE design.

Latent classes of learners in people with type 2 diabetes, stratified by educational status: A cross-sectional study

OBJECTIVE

Research suggests that people with type 2 diabetes (PWT2D) exhibit different approaches to learning about disease-management. This study's aims to identify distinct learner groups among PWT2D and stratify them by educational status (ES).

METHODS

Cross-sectional data from 227 PWT2D, collected through 46 Likert-scale questions on learning behaviors, preferences, and attitudes, were analyzed using latent class analysis, to identify learner groups. Participants were recruited via healthcare practices in central Germany and a countrywide online survey. Group membership was displayed according to low, medium, and high ES, defined by years of schooling.

RESULTS

Four learner groups were identified: casual, versatile, insecure, and theorist learners. Insecure learners accounted for almost half of all respondents in the low ES group (46 %), casual learners were most prevalent among PWT2D with a medium (27 %), versatile (34 %) and theorist (29 %) learners among those with a high ES.

CONCLUSION

This study sheds light on learner groups among PWT2D, which differ by ES, suggesting social disparities in diabetes care. Further research is needed to validate these findings.

PRACTICE IMPLICATIONS

Understanding individual learning preferences and motivations is crucial for developing effective diabetes self-management trainings, which may involve providing additional background material for theorists and practical applications for insecure learners.

Preferences of people with diabetes for diabetes care in Germany: a discrete choice experiment

OBJECTIVES

The objective of this study is to elicit health care preferences of people with diabetes and identify classes of people with different preferences.

METHODS

A discrete choice experiment was conducted among people with diabetes in Germany comprising attributes of role division in daily diabetes care planning, type of lifestyle education, support for correct medication intake, consultation frequency, emotional support, and time spent on self-management. A conditional logit model and a latent class model were used to elicit preferences toward diabetes care and analyze preference heterogeneity.

RESULTS

A total of 76 people with diabetes, recruited in two specialized diabetes care centers in Germany (mean age 51.9 years, 37.3% women, 49.1% type 2 diabetes mellitus, 50.9% type 1 diabetes mellitus), completed the discrete choice experiment. The most important attributes were consultation frequency, division in daily diabetes care planning, and correct medication intake. The latent class model detected preference heterogeneity by identifying two latent classes which differ mainly with respect to lifestyle education and medication intake.

CONCLUSION

While the majority of people with diabetes showed preferences in line with current health care provision in Germany, a relevant subgroup wished to strengthen lifestyle education and medication intake support with an aid or website.

Patient perspectives about treatment preferences for obesity with complications

Objective

Obesity and many of its comorbidities can be improved by nutritional therapy, lifestyle modification, pharmacotherapy, and surgical intervention. Relatively little is known about patients' preferences for the range of obesity treatments. The present study was undertaken to identify factors that may influence these preferences. By evaluating patient-preferred treatment options and factors influencing patients, treatment adherence and efficacy may be improved. Our objective was to identify factors that influence patient preferences and subsequent choice of obesity treatment among those seeking treatment for obesity-related complications.

Methods

Participatory action research, using purposeful sampling, was used to recruit 33 patients with obesity complications. Recruitment took place in specialist clinics for non-alcoholic fatty liver disease, diabetes, hypertension, and chronic kidney disease. Sixteen males and 17 females aged 18-70 years with a BMI>35 kg/m2 were recruited. Prior to the interview, participants watched a 60-min video explaining nutritional therapies, pharmacotherapies, and surgical therapies in equipoise. Data were collected in one-to-one semi-structured interviews using zoom or the telephone; reflective thematic analysis was used.

Results

Four themes emerged: 1) structural factors, 2) autonomy, 3) interaction with formal care, and 4) the emotional and physical consequences of obesity. 39% of participants preferred nutritional therapy with support from medical professionals. 27% chose bariatric surgery. 24% chose pharmacotherapy alone, while 6% chose pharmacotherapy combined with nutritional therapy, 3% of participants wanted no intervention.

Conclusion

The challenges can be addressed by increasing support for healthcare professionals toward enhancing both their knowledge and the health literacy of patients. Future research should focus on improving access to treatment pathways for patients as well as developing health literacy programs and educational programs for healthcare professionals.

Identifying patient preferences for diabetes care: A protocol for implementing a discrete choice experiment in Samoa

In Samoa, adult Type 2 diabetes prevalence has increased within the past 30 years. Patient preferences for care are factors known to influence treatment adherence and are associated with reduced disease progression and severity. However, patient preferences for diabetes care, generally, are understudied, and other patient-centered factors such as willingness-to-pay (WTP) for diabetes treatment have never been explored in this setting. Discrete Choice Experiments (DCE) are useful tools to elicit preferences and WTP for healthcare. DCEs present patients with hypothetical scenarios composed of a series of multi-alternative choice profiles made up of attributes and levels. Patients choose a profile based on which attributes and levels may be preferable for them, thereby quantifying and identifying locally relevant patient-centered preferences. This paper presents the protocol for the design, piloting, and implementation of a DCE identifying patient preferences for diabetes care, in Samoa. Using an exploratory sequential mixed methods design, formative data from a literature review and semi-structured interviews with n = 20 Samoan adults living with Type 2 diabetes was used to design a Best-Best DCE instrument. Experimental design procedures were used to reduce the number of choice-sets and balance the instrument. Following pilot testing, the DCE is being administered to n = 450 Samoan adults living with diabetes, along with associated questionnaires, and anthropometrics. Subsequently, we will also be assessing longitudinally how preferences for care change over time. Data will be analyzed using progressive mixed Rank Order Logit models. The results will identify which diabetes care attributes are important to patients (p < 0.05), examine associations between participant characteristics and preference, illuminate the trade-offs participants are willing to make, and the probability of uptake, and WTP for specific attributes and levels. The results from this study will provide integral data useful for designing and adapting efficacious diabetes intervention and treatment approaches in this setting.

Supporting professionals to implement integrated, person-centered care for people with chronic conditions: the TARGET pilot study

OBJECTIVE

The TARGET program for integrated, person-centered care for people with chronic conditions offers primary care (PC) professionals a set of tools and trainings to actively engage in population segmentation and person-centered needs assessments (PCNAs). A pilot study was conducted to gain insight into the program's feasibility and acceptability, and identify preconditions for successful implementation.

DESIGN AND SETTING

Seven Dutch PC practices participated in a half-year pilot study starting in August 2020. We performed a review of the population segmentation tool, observed four training sessions and 15 PCNAs, and interviewed 15 professionals and 12 patients.

RESULTS

Regarding feasibility and acceptability, we found that the tools and trainings provided professionals with skills to use the segmentation tool and take a more coaching role in the well-appreciated PCNAs. Concerning implementation preconditions, we found that team commitment and network connections need improvement, although work pleasure increased and professionals generally wanted the program to continue.

CONCLUSIONS

While the content of the TARGET program is supported by its users, the implementation process, for instance team commitment to the program, needs more attention in future upscaling efforts.

Feasibility and acceptability of 'low-intensity mental health support via a telehealth-enabled network' for adults with type 1 and type 2 diabetes: the LISTEN pilot study

BACKGROUND

This study examined the feasibility and acceptability of the low-intensity mental health support via telehealth-enabled network (LISTEN) intervention, for adults with diabetes, facilitated by diabetes health professionals (HPs).

METHODS

LISTEN training. Three HPs participated in three half-day online workshops and applied their learnings during training cases (maximum four). Competency was assessed with a validated tool and achieved 'satisfactory' ratings for three consecutive sessions. LISTEN pilot. A single-group, pre-post study (up to four LISTEN sessions) with online assessments at baseline, post-intervention, and 4-week follow-up. Eligible participants were adults with type 1 or type 2 diabetes, with diabetes distress, but excluded if they had moderate/severe depressive and/or anxiety symptoms. Feasibility was assessed via recruitment and session completion rates. Acceptability was assessed with post-intervention self-report data. Changes in diabetes distress and general emotional well-being from baseline (T1) were explored at post-intervention (T2) and at 4-week follow-up (T3).

RESULTS

Two HPs achieved competency (median training case sessions required: 7) and progressed to deliver LISTEN in the pilot study. In the pilot, N = 16 adults (Med [IQR] age: 60 [37-73] years; 13 women) with diabetes participated (median sessions per participant: 2). Twelve participants (75%) completed the post-intervention assessment (T2): 92% endorsed the number of sessions offered as 'just right', 75% felt comfortable talking with the HP, and 67% were satisfied with LISTEN. Perceived limitations were the structured format and narrow scope of problems addressed. Diabetes distress scores were lower post-intervention.

CONCLUSIONS

This pilot demonstrates the feasibility of training HPs to deliver LISTEN, and the acceptability and potential benefits of LISTEN for adults with diabetes. The findings highlight adaptations that may enhance the delivery of, and satisfaction with, LISTEN that will be tested in a hybrid type 1 effectiveness-implementation trial.

DiaFocus: A Personal Health Technology for Adaptive Assessment in Long-Term Management of Type 2 Diabetes

Type 2 diabetes (T2D) is a large disease burden worldwide and represents an increasing and complex challenge for all societies. For the individual, T2D is a complex, multi-dimensional, and long-term challenge to manage, and it is challenging to establish and maintain good communication between the patient and healthcare professionals. This article presents DiaFocus, which is a mobile health sensing application for long-term ambulatory management of T2D. DiaFocus supports an adaptive collection of physiological, behavioral, and contextual data in combination with ecological assessments of psycho-social factors. This data is used for improving patient-clinician communication during consultations. DiaFocus is built using a generic data collection framework for mobile and wearable sensing and is highly extensible and customizable. We deployed DiaFocus in a 6-week feasibility study involving 12 patients with T2D. The patients found the DiaFocus approach and system useful and usable for diabetes management. Most patients would use such a system, if available as part of their treatment. Analysis of the collected data shows that mobile sensing is feasible for longitudinal ambulatory assessment of T2D, and helped identify the most appropriate target users being early diagnosed and technically literate T2D patients.

People with type 2 diabetes' experiences of emotional support in Australian general practice: a qualitative study

BACKGROUND

Diabetes distress, experienced by up to 40% of people with type 2 diabetes (T2D), is the negative emotional response to the burden of living with and managing diabetes. It is associated with suboptimal glycaemia and diabetes self-management. Research indicates that people with diabetes do not recall being asked about emotional distress by healthcare professionals.

AIM

To explore the experiences, needs, and expectations of people with T2D regarding emotional support received in Australian general practice.

DESIGN & SETTING

Exploratory qualitative study in Victoria, Australia.

METHOD

Semi-structured interviews were undertaken to explore emotional health and support received in general practice in 12 adults with T2D who primarily attend general practice. Interviews were audio-recorded, transcribed verbatim, and analysed using the framework approach.

RESULTS

The following three major themes were identified: (1) Beneath the surface of diabetes care; (2) Importance of GP-patient relationship; and (3) Communication counts. Participants experienced diabetes care as focused primarily on medical management rather than the emotional aspects of living with T2D. While people's experiences of diabetes care in general practice primarily focused on physical health, the GP care beyond the presenting complaint has an essential role in identifying emotional issues and enabling support. Emotional issues were more likely to be discussed and acknowledged by the GP where there was a long-standing relationship between GP and patient.

CONCLUSION

Pre-existing positive GP-patient relationships and supportive communication enable people with 2TD to raise emotional issues as part of diabetes care.

Investigating patients' preferences for new anti-diabetic drugs to inform public health insurance coverage decisions: a discrete choice experiment in China

Background

Diabetes is a major public health concern with a considerable impact on healthcare expenditures. Deciding on health insurance coverage for new drugs that meet patient needs is a challenge facing policymakers. Our study aimed to assess patients’ preferences for public health insurance coverage of new anti-diabetic drugs in China.

Methods

We identified six attributes of new anti-diabetic drugs and used the Bayesian-efficient design to generate choice sets for a discrete choice experiment (DCE). The DCE was conducted in consecutive samples of type 2 diabetes patients in Jiangsu Province. The mixed logit regression model was applied to estimate patient-reported preferences for each attribute. The interaction model was used to investigate preference heterogeneity.

Results

Data from 639 patients were available for analysis. On average, the most valued attribute was the improvement in health-related quality of life (HRQoL) (β = 1.383, p < 0.001), followed by positive effects on extending life years (β = 0.787, p < 0.001), and well-controlled glycated haemoglobin (β = 0.724, p < 0.001). The out-of-pocket cost was a negative predictor of their preferences (β = -0.138, p < 0.001). Elderly patients showed stronger preferences for drugs with a lower incidence of serious side effects (p < 0.01) and less out-of-pocket costs (p < 0.01). Patients with diabetes complications favored more in the length of extended life (p < 0.01), improvement in HRQoL (p < 0.05), and less out-of-pocket costs (p < 0.001).

Conclusion

The new anti-diabetic drugs with significant clinical effectiveness and long-term health benefits should become the priority for public health insurance. The findings also highlight the value of accounting for preference heterogeneity in insurance policy-making.

Preferences of oral nutritional supplement therapy among postoperative patients with gastric cancer: Attributes development for a discrete choice experiment

Background

Adherence to oral nutritional supplement therapy among postoperative patients with gastric cancer is low. There is little knowledge about patients’ priorities and needs regarding oral nutritional supplement therapy. The discrete choice experiment is an innovative method used to elicit patients’ preferences. Good practice guidelines emphasize that the development of attributes and levels is a fundamentally important process.

Objective

To comprehensively describe the identification, refinement, and selection of attributes and levels for a discrete choice experiment.

Methods

A mixed-methods approach, consisting of three consecutive steps: a literature review, in-depth interviews, and focus groups. First, the literature review allowed quick identification of attributes and levels. Then, 15 in-depth interviews were conducted to gather a rich description of the experience of patients taking oral nutritional supplements after gastrectomy and to verify and enrich the attributes and levels list. Finally, four focus group participants discussed the wording of the attributes and levels and reduced the number of attributes to manageable numbers through voting ranking methods.

Results

Following the literature review and qualitative data collection, eight attributes were finally generated, each with two to three levels. The following attributes were included: 1) information provider; 2) health guidance approach; 3) adverse reactions; 4) flavor; 5) follow-up method; 6) follow-up frequency; 7) psychological support; 8) cost. These attributes covered the important attributes of nutritional preparations and health guidance included in ONS therapy that were relevant to patients.

Conclusions

This study’s mixed-methods approach has been found highly suitable to identify, refine and select attributes and levels for a discrete choice experiment. The three methods have pros and cons, and they complement each other, especially the analysis of qualitative data led to a deeper and broader understanding of attributes and levels.

Preferences for oral nutritional supplement therapy among postoperative patients with gastric cancer: a discrete choice experiment

Purposes

Patients after gastrectomy have poor compliance with oral nutritional supplement (ONS) therapy. Incorporating patient preferences into treatment decisions allows possible product improvements or treatment focus adjustments. The purpose of this research was to investigate the preferences for ONS therapy among postoperative patients with gastric cancer, and to provide person-centered oral nutrition management strategies.

Methods

A discrete choice experiment was designed and implemented within a Chinese cancer population. The survey was administered via paper-based questionnaires during face-to-face interviews with assistance from health professionals. A mixed logit model was used to estimate respondents’ preferences for different levels of nutrition therapy attributes.

Results

One hundred ninety respondents valued “Adverse reactions-almost none” (β 3.43 [SE, 0.28]) the most, followed by “Flavor-good taste” (β 0.68 [SE, 0.13]) and “Follow-up frequency-once every 2 weeks” (β 0.52 [SE, 0.13]), and were willing to pay more for these attribute levels. Respondents would be 93.73% more likely to accept a nutrition therapy program if there were almost no adverse reactions compared to the frequent adverse reactions.

Conclusions

Health professionals should pay attention to the management and prevention of adverse reactions when prescribing nutritional products, and provide diversified ONS products when necessary to meet patient preferences. When formulating intervention strategies, health professionals should also consider the different characteristics of patients, acknowledge the importance of the role of nurse specialists in a novel model of multidisciplinary nutritional care, standardize ONS information, follow up regularly, and encourage patients’ families to participate in daily nutrition care.

From the United Kingdom to Australia-Adapting a Web-Based Self-management Education Program to Support the Management of Type 2 Diabetes: Tutorial

Diabetes self-management education and support can improve outcomes in people with diabetes. Providing health interventions via digital modes of delivery can extend the reach of programs delivered through traditional means. The web-based version of the Diabetes Education and Self-Management for Ongoing and Newly Diagnosed (MyDESMOND) is a digital diabetes education and support program for people with type 2 diabetes. The program was originally developed in the United Kingdom and is evidence-based, grounded in behavioral theory, and designed through a rigorous process of intervention mapping. As such, MyDESMOND was considered an ideal candidate for adaptation to the Australian setting. Program content and the digital platform were modified to suit the local context to increase the likelihood that the revised version of MyDESMOND will deliver similar outcomes to the original program. The aim of this paper is to describe the systematic processes undertaken to adapt the digital MyDESMOND diabetes education and support program for people with type 2 diabetes to the Australian setting. The adaptation involved a multidisciplinary group with a diverse range of skills and expertise-a governance structure was established, a skilled project team was appointed, and stakeholder engagement was strategically planned. The adaptation of the program content included modifications to the clinical recommendations, the inclusion of local resources, practical changes, and revisions to optimize readability. A 2-stage independent review of the modified content was enacted. Digital adaptations were informed by relevant standards, local legislative requirements, and considerations of data sovereignty. The digital platform was extensively tested before deployment to the production setting. MyDESMOND is the first evidence-based digital diabetes education and support program for Australians with type 2 diabetes. This paper provides a road map for the adaptation of digital health interventions to new contexts.

Q-Methodology and Psychological Phenotyping to Design Patient-Centered Diabetes Education for Persons With Type 2 Diabetes on Insulin Therapy

PURPOSE

The purpose of this study was to identify the psychological phenotypes of persons with type 2 diabetes (T2D) on insulin therapy to better inform personalized diabetes education strategies to improve self-management behaviors.

METHODS

Q-methodology, a research approach combining the quantitative rigor of statistical analysis with qualitative data on perception of diabetes self-management by persons with T2D on insulin therapy, was used. The Summary of Diabetes Self-Care Activity measure and A1C in the past 6 months were used to further describe self-management behaviors of each P-sample, Q-sorter. Of 160 statements, 33 Q-sample statements were selected as Q-set. Then, 37 P-samples (24 men; 13 women) were recruited from a university-affiliated diabetes clinic in South Korea. Data obtained from each P-sample with a Q-set and a Q-sorting table, a forced-choice normal distribution table, were analyzed using varimax rotation.

RESULTS

Forty-one percent of the variance was explained with 5 factors represented by 27 Q-sorters, explaining variance ranging from 5% to 17% for each factor: Factor A (n = 6): those showing self-management education need but possessing inadequate health literacy; Factor B (n = 4): those valuing lifestyle modification to control diabetes; Factor C (n = 5): those valuing antidiabetic medication to control diabetes; Factor D (n = 6): carpe diem, accepting diabetes as destiny; and Factor E (n = 6): those overestimating their competencies to control diabetes. Ten Q-sorters fell into either confounded or nonsignificant.

CONCLUSIONS

Tailoring messages and educational approaches based on patients' psychological phenotypes are necessary to promote optimal self-management behaviors.

Pharmacists' preferences for the provision of services to improve medication adherence among patients with diabetes in Indonesia: Results of a discrete choice experiment

Little is known about pharmacists' preferences for services to improve medication adherence in patients with diabetes in Indonesia. Identification of such preferences can provide valuable insights on suitable services from a pharmacist's perspective. This study elicits pharmacists' preferences for services to improve medication adherence among their patients. A discrete choice experiment (DCE) method was used to survey pharmacists in all community health centres and three hospitals in Surabaya, Indonesia. Four attributes of consultation, namely duration of consultation, place of consultation, access to a pharmacist and patient copayment, and two attributes on additional services (educational and behavioural-based services) were included. The 16 profiles generated for DCE were partially balanced and partially without overlap. A random-effect logistic regression was used in the analysis. In total, 99 pharmacists completed the questionnaire, but only 80 were included in the study based on a consistency check. All attributes were found to determine preferences for a pharmacist service package. Pharmacists preferred a consultation with a shorter duration accompanied by flexible access to the pharmacist as well as a private consultation room and a lower patient copayment. Providing the patient with a brochure/leaflet was the most preferred additional service to help improve medication adherence. Patient group discussion and medication review were also preferred in combination with a consultation. Pharmacists' socio-demographic background characteristics influence preferences. These findings can be considered in evaluating current practice and designing pharmacist services to help improve medication adherence among patients with diabetes.

'Water dripping on a stone': a feasibility study of a healthy weight management conversation approach in routine general practice consultations

BACKGROUND

Primary health care has an important role to play in the management of weight and yet discussions of healthy weight management do not occur optimally, indicating a need for simple tools and training in brief weight counselling. The 'FABS' approach (focusing on four topic areas: Food, Activity, Behaviour and Support) was developed to address this.

OBJECTIVES

To explore the feasibility of the 'FABS' approach within routine general practice consultations and its effectiveness in facilitating healthy weight conversations.

METHOD

The FABS approach was run for a trial period in five New Zealand general practices. The approach entailed staff training, the addition to the practice patient management system of a template outlining potential topics for discussion and a patient handout. GPs were asked to use the approach with any adult patient with a body mass index of over 28 kg/m2. A descriptive analysis of anonymized quantitative practice data was conducted, with limited qualitative data from an online clinician questionnaire and interviews with GPs and patients.

RESULTS

Over 4 months, the template was opened 862 times by 27 clinicians in 830 patient consultations. All FABS topics were raised at least once. Physical activity was raised most frequently, followed by two food-related topics. There was variation between practices and between GPs. GPs tended to raise more topics within a single consultation than the training recommended. The limited clinician survey results and patient interviews also indicated positive responses to the approach.

CONCLUSIONS

It is possible to provide an infrastructure for healthy weight conversation approaches within general practice so that patients receive supportive and consistent messages on a regular basis. General practice is an appropriate setting for this due to the ongoing relationships with patients and team-based approach, but there is a need for effective training and education to ensure appropriate and effectively delivery.

Preferences of people with Type 2 diabetes for diabetes care: a discrete choice experiment

AIMS

Limited knowledge exists on the preferences of people with Type 2 diabetes towards diabetes care. Consequently, these care preferences cannot yet be considered in the development of tailored diabetes care approaches. Therefore, this study aimed to assess care preferences and their determinants in people with Type 2 diabetes.

METHODS

A discrete choice experiment was conducted to elicit people's preferences. People with Type 2 diabetes, treated in 30 Dutch primary care practices, were asked to choose repeatedly between two hypothetical diabetes care packages, which differed in six attributes: role division in daily diabetes care planning, lifestyle education method, type of medication management support, consultation frequency, emotional support and time spend on self-management. A mixed-logit model was used to estimate the relative importance of the included attributes. Preference heterogeneity among people with different person- and disease-related characteristics was investigated.

RESULTS

In total, 288 participants completed the experiment. They preferred to plan their daily diabetes care together with a healthcare provider, to receive individual lifestyle education, medication and emotional support from a healthcare provider, one consultation visit every 3 months and to spend less time on self-management. Participants did not prefer to receive emotional support from a psychologist. Heterogeneity in preferences could partly be explained by differences in sex, education level and glucose-lowering drug use.

CONCLUSION

People with Type 2 diabetes show a preference for traditional care models. Emotional support was identified by participants as the most important attribute. It is therefore important to adequately guide them when changes in diabetes care organization are implemented.

Understanding Reasons for Treatment Discontinuation, Attitudes and Education Needs Among People Who Discontinue Type 2 Diabetes Treatment: Results from an Online Patient Survey in the USA and UK

INTRODUCTION

Type 2 diabetes mellitus (T2DM) requires long-term treatment to achieve and maintain glycaemic control; however, up to 50% of people with T2DM discontinue treatment by 1 year. It is therefore important to understand the patient perspective of therapeutic adherence and persistence.

METHODS

An online questionnaire was presented to people with T2DM in the USA and UK on PatientLive®, a platform of Carenity, an online patient community. Those who discontinued at least one T2DM treatment within the last 6 months answered open-ended questions aimed to assess the reasons for discontinuation, how discontinuation could have been prevented, and what would have improved the experience with the discontinued treatment. Thematic qualitative analysis was performed on respondents' answers to these questions.

RESULTS

Oral antidiabetics were the most commonly discontinued treatments (93/161), followed by insulin (40/161) and glucagon-like peptide 1 receptor agonists (13/161). Main reasons for treatment discontinuation overall were side effects (57/161), mostly gastrointestinal side effects and weight gain. The second most reported reason was drug efficacy issues (42/161). Key factors stated to prevent discontinuation were an improved care pathway (45/161) and more efficacious treatments with fewer side effects (41/161). In the USA, treatment cost played an important role in discontinuation (14/89) and discontinuation prevention (12/89). More information about T2DM and associated treatments (56/161), help with T2DM management (24/161), and increased and informative patient-physician interaction (12/161) would have been helpful for many respondents in both countries, while some patients noted that no additional information would have been useful to improve their understanding and experience with their T2DM treatment (64/161).

CONCLUSIONS

These results emphasise the need for focused medical education and improved communication to enhance patient experience and prevent treatment discontinuation. Understanding of attributes preferred by people with T2DM can help improve therapeutic adherence and outcomes with current medications, and guide development of future therapies.

Using discrete choice experiments to develop and deliver patient-centered psychological interventions: a systematic review

Developing and/or tailoring psychological interventions to align with patient preferences is a critical component of patient-centered care and has the potential to improve patient engagement and treatment outcomes. Discrete choice experiments (DCEs) are a quantitative method of assessing patient preferences that offer numerous strengths (i.e., ability to account for trade-offs), but are not routinely incorporated into health psychology coursework, likely leaving many unaware of the potential benefits of this methodology. To highlight the potential applications of DCEs within health psychology, this systematic review synthesises previous efforts to utilise DCEs to inform the design of patient-centered psychological care, defined as interventions targeting psychological (e.g., depression, anxiety) or behavioural health (e.g., pain management, adherence) concerns. Literature searches were conducted in March 2017 and November 2019 for articles reporting on DCEs using the terms 'discrete choice', 'conjoint', or 'stated preference'. Thirty-nine articles met all inclusion criteria and used DCEs to understand patient preferences regarding psychosocial clinical services (n = 12), lifestyle behaviour change interventions (n = 11), HIV prevention and/or intervention services (n = 10), disease self-management programmes (n = 4), or other interventions (n = 2). Clinical implications as well as limitations and directions for future research are discussed.

Integrating behaviour change counselling into chronic disease management: a square peg in a round hole? A system-level exploration in primary health care

OBJECTIVES

The objective of this study is to evaluate the uptake of competency-based behaviour change counselling training within a primary healthcare setting. Specific questions concerning provider readiness for training, perceived importance of training in the context of service demands and perceptions of competence after training were addressed.

STUDY DESIGN

A process-focused study which adopted a complex systems approach to implementation. Each step was evaluated before the next step was developed. The design was guided by the RE-AIM (reach, effectiveness, adoption, implementation, maintenance) framework.

METHODS

Four specific primary care services were identified and behaviour change counselling training tailored to each service was provided, based on a model of training built around competencies in establishing change-based relationships, assessing and promoting readiness to change, using evidence-based behaviour modification skills when ready and addressing psychosocial determinants of behaviour within scope of practice. Before training, a manager's readiness to facilitate training and identification of peer leaders to support ongoing practice of skills were completed.

RESULTS

Two programs negotiated 8 h of formal training, one program received 10 h and one program received 12 h. All programs engaged in peer support activities. Despite willingness to support training, 90% of managers were ambivalent about training activities, relative to one half of healthcare providers (HCPs). Few HCPs and no managers self-identified as ready without ambivalence. Furthermore, HCPs were reluctant to be evaluated by an expert and preferred self-evaluation methods. In contrast, HCPs uniformly endorsed the relevance, value and professional commitment to all component skills of the behaviour change counselling model. At the end of the training, over 75% of staff reported receiving formal training (reach). Almost 80% of staff reported using change-based relationship skills daily, with less frequent use of skills associated with addressing psychosocial issues. The degree of corrective feedback was generally low, however. An index of competency based on formal training, frequent use and receiving corrective feedback indicated that most HCPs did not meet these criteria.

CONCLUSION

Training in behaviour change counselling competencies was successfully implemented in this project. The vast majority of HCPs received training, despite ambivalence. Furthermore, HCPs strongly valued these skills and used them frequently. However, they were reluctant to accept corrective feedback. Future research is needed to evaluate innovative strategies to overcome obstacles to receiving corrective feedback in the use of behaviour change counselling skills.
