Development of a discrete choice experiment questionnaire to elicit preferences by pregnant women and policymakers for the expansion of non-invasive prenatal screening.

ABSTRACT:

Objective

An instrument for measuring intervention preferences applicable to both patients and policymakers would make it possible to better confront the needs of the supply and demand sides of the health care system. This study aimed to develop a discrete choice experiments (DCE) questionnaire to elicit the preferences of patients and policymakers. The instrument was specifically developed to estimate preferences for new conditions to be added to a screening program for fetal chromosomal anomalies.

Methods

A DCE development study was conducted. The methods employed included a literature review, a qualitative study (based on individual semi-structured interviews, consultations, and a focus group discussion) with pregnant women and policymakers, and a pilot project with 33 pregnant women to validate the first version of the instrument and test the feasibility of its administration.

Results

An initial list of 10 attributes was built based on a literature review and the qualitative research components of the study. Five attributes were built based on the responses provided by the participants from both groups. Eight attributes were consensually retained. A pilot project performed on 33 pregnant women led to a final instrument containing seven attributes: 'conditions to be screened', 'test performance', 'moment at gestational age to obtain the test result', 'degree of test result certainty to the severity of the disability', 'test sufficiency', 'information provided from test result', and 'cost related to the test'.

Conclusion

It is possible to reach a consensus on the construction of a DCE instrument intended to be administered to pregnant women and policymakers. However, complete validation of the consensual instrument is limited because there are too few voting members of health technology assessment agencies committees to statistically ascertain the relevance of the attributes and their levels.

Project description:ObjectiveOur objective was to develop and test a discrete-choice experiment (DCE) survey to elicit adolescent and parent preferences for dental care for hypodontia (a developmental condition where one or more teeth fail to develop).MethodsThis was a mixed-methods study. Participants were adolescents (aged 12-16 years) with hypodontia and their parents and the dentists providing hypodontia care. Stage one entailed attribute development, as follows. (1) Attribute identification: systematic review of hypodontia literature; interviews with adolescents with hypodontia (n = 8) and parents (n = 8); observation of hypodontia clinical consultations (n = 5); environmental scan of hypodontia patient information resources (n = 30); and systematic analysis of social media posts (n = 176). (2) Attribute selection: stakeholder consultation to develop items for a questionnaire; rating and ranking questionnaire for adolescents with hypodontia and parents (n = 18); further stakeholder consultation. Stage two involved the development of the DCE survey, and stage three included the pre-testing using cognitive interviews with adolescents (n = 12) and parents (n = 8) to assess face and content validity.ResultsThe attribute long list included 27 attributes focusing on service delivery and treatment outcome, from which seven 'important' attributes were selected for pre-testing. Cognitive interviewing suggested adolescents found the DCE choice tasks challenging to understand; the survey was modified to enhance its acceptability. One attribute was excluded as it showed poor validity with adolescents. Pre-testing suggested DCE choice tasks encouraged thinking and discussion about preferences for treatment.ConclusionsIncluding the target respondent group in all stages of DCE development ensured the final DCE survey was valid and acceptable. DCE methods appear to be a useful tool for exploring joint decision making alongside conventional preference elicitation.

Project description:ObjectivesNoninvasive prenatal testing (NIPT) to screen for fetal aneuploidies by analysing cell-free DNA in maternal plasma is available to pregnant women worldwide. In the future, the scope of NIPT could potentially be expanded to the prediction of adverse pregnancy outcomes. The objective of this study was to assess and compare the preferences of pregnant women and obstetric healthcare professionals on this new test purpose of NIPT.DesignA discrete choice experiment was designed to assess participants' preferences on the use of NIPT to predict adverse pregnancy outcomes regarding three attributes on test characteristics: test accuracy rate, unnecessary intervention rate and false reassurance rate. A questionnaire assessed general attitudes towards using noninvasive prenatal testing to predict adverse pregnancy outcomes.SettingDutch prenatal healthcare system.ParticipantsPregnant women with singleton pregnancies and obstetric healthcare professionals.ResultsIn total, 1580 pregnant women and 308 obstetric healthcare professionals participated in the discrete choice experiment. Higher test accuracy, fewer unnecessary interventions and less false reassurance all had a statistically significant (p<0.05) impact on the preference for a test. For pregnant women, the most important test characteristic when choosing a preferred test was the test accuracy rate, while for obstetric healthcare professionals, the most important test characteristic was the unnecessary intervention rate. The false reassurance rate was the least important test characteristic for both groups. Overall, 74% (n=1181) of pregnant women (strongly) agreed that NIPT to predict adverse pregnancy outcomes should be offered to pregnant women compared with 49% (n=151) of obstetric healthcare professionals.ConclusionsMost pregnant women have a positive attitude towards using NIPT to predict adverse pregnancy outcomes compared with slightly less than half of the obstetric healthcare professionals. Pregnant women prioritise a prognostic test with higher test accuracy, while obstetric healthcare professionals prioritise a test that results in fewer unnecessary interventions.

Project description:BackgroundUnderstanding mental health treatment preferences of adolescents and youth is particularly important for interventions to be acceptable and successful. Person-centered care mandates empowering individuals to take charge of their own health rather than being passive recipients of services.MethodsWe conducted a discrete choice experiment to quantitatively measure adolescent treatment preferences for different care characteristics and explore tradeoffs between these. A total of 153 pregnant adolescents were recruited from two primary healthcare facilities in the informal urban settlement of Nairobi. We selected eight attributes of depression treatment option models drawn from literature review and previous qualitative work. Bayesian d-efficient design was used to identify main effects. A total of ten choice tasks were solicited per respondent. We evaluated mean preferences using mixed logit models to adjust for within subject correlation and account for unobserved heterogeneity.ResultsRespondents showed a positive preference that caregivers be provided with information sheets, as opposed to co-participation with caregivers. With regards to treatment options, the respondents showed a positive preference for 8 sessions as compared to 4 sessions. With regards to intervention delivery agents, the respondents had a positive preference for facility nurses as compared to community health volunteers. In terms of support, the respondents showed positive preference for parenting skills as compared to peer support. Our respondents expressed negative preferences of ANC service combined with older mothers as compared to adolescent friendly services and of being offered refreshments alone. A positive preference was revealed for combined refreshments and travel allowance over travel allowance or refreshments alone. A number of these suggestions were about enhancing their experience of maternity clinical care experience.ConclusionThis study highlights unique needs of this population. Pregnant adolescents' value responsive maternity and depression care services offered by nurses. Participants shared preference for longer psychotherapy sessions and their preference was to have adolescent centered maternal mental health and child health services within primary care.

Project description:BackgroundColorectal cancer (CRC) is the second most deadly form of cancer, inducing an estimated 1.9 million incidence cases and 0.9 million deaths worldwide in 2020. Despite the availability of screening tests, their uptake remains suboptimal. However, blood-based tests that look for signs of cancer-specific markers in the body are increasingly available as an alternative for more invasive tests for cancer. Compared with existing tests, the benefits of blood-based tests for CRC include not needing pretest preparation, stool handling, and dietary or medication restrictions.ObjectiveThis study aims to explore the population's preferences for CRC screening tests, with a focus on blood-based tests, and investigate the factors influencing test uptake.MethodsWe used a mixed methods approach, combining semistructured interviews and a discrete choice experiment (DCE) survey. Interviews were analyzed using thematic analysis to identify salient attributes for CRC screening tests. These attributes informed the design of the DCE survey. The DCE data were analyzed using mixed logit and mixed-mixed multinomial logit models.ResultsQualitative findings from 30 participants revealed that participants preferred blood-based tests due to their perceived low risk, minimal pain, and ease of sample collection. However, concerns about the test's lower accuracy were also expressed. The DCE survey was completed by 1189 participants. In the mixed logit model, participants demonstrated a stronger preference for blood-based tests over a 2-day stool-based test. The mixed-mixed multinomial logit model identified 2 classes, strong supporters and weak supporters, for CRC screening. Weak supporters, but not strong supporters, had a higher preference for blood-based tests. Women, ethnic Chinese, and people aged 40 to 60 years were more likely to be weak supporters. Both models highlighted the high influence of cost and test sensitivity on participants' preferences. Transitioning from a 2-day stool-based test to a blood-based test, assuming a national screening program at a base price of Singapore $5 (US $3.75), was estimated to have the potential to increase the relative uptake by 5.9% (95% CI 3.6%-8.2%).ConclusionsThese findings contribute to our understanding of CRC screening preferences and provide insights into the factors driving test uptake. This study highlights the perceived advantages of blood-based tests and identifies areas of concern regarding their accuracy. Further research is needed to determine the actual increase in uptake rate when blood-based tests are made available.

Project description:OBJECTIVES:It is desirable that public preferences are established and incorporated in emergency healthcare reforms. The aim of this study was to investigate preferences for local versus centralised provision of all emergency medical services (EMS) and explore what individuals think are important considerations for EMS delivery. DESIGN:A discrete choice experiment was conducted. The attributes used in the choice scenarios were: travel time to the hospital, waiting time to be seen, length of stay in the hospital, risks of dying, readmission and opportunity for outpatient care after emergency treatment at a local hospital. SETTING:North East England. PARTICIPANTS:Participants were a randomly sampled general population, aged 16 years or above recruited from Healthwatch Northumberland network database of lay members and from clinical contact with Northumbria Healthcare National Health Service Foundation Trust via Patient Experience Team. PRIMARY AND SECONDARY OUTCOME MEASURES:Analysis used logistic regression modelling techniques to determine the preference of each attribute. Marginal rates of substitution between attributes were estimated to understand the trade-offs individuals were willing to make. RESULTS:Responses were obtained from 148 people (62 completed a web and 86 a postal version). Respondents preferred shorter travel time to hospital, shorter waiting time, fewer number of days in hospital, low risk of death, low risk of readmission and outpatient follow-up care in their local hospital. However, individuals were willing to trade off increased travel time and waiting time for high-quality centralised care. Individuals were willing to travel 9 min more for a 1-day reduction in length of stay in the hospital, 38 min for a 1% reduction in risk of death and 112 min for having outpatient follow-up care at their local hospital. CONCLUSIONS:People value centralised EMS if it provides higher quality care and are willing to travel further and wait longer.

Project description:BackgroundPsychiatric nurses are instrumental in enhancing accessibility to care and addressing the mental health care needs of individuals. However, the field faces a significant shortage of nurses coupled with a high turnover rate. Developing policies to attract or retain psychiatric nurses is imperative, but little is known about the preferences of psychiatric nurses regarding the economic and non-economic attributes of work. Here, a discrete choice experiment (DCE) was used to explore psychiatric nurses' job preferences.MethodsA survey instrument was developed adhering to the design-principles of DCE. Psychiatric nurses were surveyed nationwide based on convenience sampling. A mixed logit model was used to estimate the psychiatric nurses' preferences. Willingness to pay was calculated and the change in the probability of psychiatric nurses accepting a job when attribute levels changed was simulated.ResultsThe attribute level most valued by respondents was 'violent coping strategies-impeccable' (coefficient = 1.002, p < 0.01) and willingness to pay for it is 4476.5323 CNY. The most important attribute level for psychiatric nurses living in cities was 'respect-high' (coefficient = 0.505, p < 0.01), and for psychiatric nurses living in town is 'study assistance for children-thorough' (coefficient = 0.620, p < 0.01). Notably, psychiatric nurses with less than ten years of work experience exhibited significant preferences for 'opportunity to upgrade-sufficient' (coefficient = 0.417, p < 0.01), whereas this preference was insignificant among those with ten years or more of experience (p > 0.05). Changing 'violence coping strategies' from 'without' to 'impeccable' increased the probability of psychiatric nurses accepting the job by 37.04%. The optimal job increased the probability of psychiatric nurses accepting the job by 86.06%.ConclusionPsychiatric nurses would prefer jobs with higher income, more respect, better coping strategies with violence, better opportunities for promotion, and a good working atmosphere. Psychiatric nurses with different seniority and residence had different preferences.

Project description:Choosing hypodontia treatment requires young people and parents to consider a large amount of information, identify what is important to them, and make trade-offs between options. This study aimed to examine young people and parents' preferences for hypodontia treatment using discrete choice experiment (DCE). This was a cross-sectional survey of young people (12-16 y) with hypodontia of any severity, at any stage of treatment, and their parents. Participants were recruited from NHS Hospitals in England and Wales. A bespoke DCE questionnaire was developed to measure preferences for 6 attributes of hypodontia treatment (waiting time, treatment time, problems during treatment, discomfort during treatment, bite, appearance). The questionnaire was completed 1) online by young people and parents, individually or together, and 2) by child-parent dyads under observation. Preferences were analyzed using regression models. In total, 204 participants (122 young people, 56 parents, 26 dyads) completed the online questionnaire and 15 child-parent dyads completed the questionnaire under observation. The most important attribute in hypodontia treatment was improvement in appearance, but significant heterogeneity was found in preferences. Four distinct groups of participants were found: group 1 (39%): severe discomfort and problems were most important; group 2 (31%): most concerned about improvement in appearance of teeth and improvement in bite; group 3 (22%): appearance 3 times more important than any other attribute; and group 4 (9%): preferences difficult to interpret. There was variation in how child-parent dyads approached decision-making, with some negotiating joint preferences, while for others, one individual dominated. Making trade-offs in DCE tasks helped some people think about treatment and identify their preferences. Appearance is an important outcome from hypodontia treatment, but preferences vary and potential risks and functional outcome are also important to some people. There is a notable level of uncertainty in decision-making, which suggests further shared decision support would be valuable.
