The feasibility of using the EQ-5D-3L with adults with mild to moderate learning disabilities within a randomized control trial: a qualitative evaluation

Quality-of-life measurement in randomised controlled trials of mental health interventions for autistic adults: A systematic review

Autistic people are more likely to have co-occurring mental health conditions compared to the general population, and mental health interventions have been identified as a top research priority by autistic people and the wider autism community. Autistic adults have also communicated that quality of life is the outcome that matters most to them in relation to mental health research and that they want to be involved more actively in the research process. Our systematic review aimed to determine the extent and nature of (1) quality of life measurement in randomised controlled trials of mental health interventions for autistic adults and (2) community involvement taking place within identified randomised controlled trials. We searched Medline, Embase, APA PsycInfo, Web of Science and grey literature sources. After screening over 10,000 records, 19 studies were eligible and five of those studies measured quality of life as an outcome. Of those five, three included community involvement and two did not report on community involvement. We conclude there is a need for increased use of quality of life measurement when trialling mental health interventions, including the use of measures validated for autistic adults - which would be facilitated by greater autistic involvement in the research process.Lay AbstractAutistic people are more likely to have health problems than the general population. They, and people who care about them, have said mental health research is very important, and some autistic adults have said quality of life is the most helpful area to research when focusing on mental health. Autistic people should also be more deeply involved in making decisions in research. Our review aimed to find out if and how quality of life is being measured when mental health treatments are being tested, and how autistic people and the wider autism community are involved in these studies. We searched four databases and other sources and found over 10,000 records. But just 19 research studies were testing mental health treatments for autistic adults, and only five of those measured quality of life. When they did measure quality of life, it was measured in different ways and there was not much information given on how communities were involved. We suggest mental health research should measure quality of life more often and in ways that are more helpful for autistic people. Our analysis found that mental health research needs to include a wider variety of autistic people, and autistic people should be more involved in the various parts of research.

Adapting the EQ-5D-3L for adults with mild to moderate learning disabilities

BACKGROUND

Approximately 1.5 million adults in the UK have a learning disability. The difference between age at death for this group and the general population is 26 years for females and 22 years for males. The NHS Long Term Plan (January 2019) recognises learning disabilities as a clinical priority area. People with a learning disability are often excluded from research by design or lack of reasonable adjustments, and self-reported health status/health-related quality of life questionnaires such as the EQ-5D are often not appropriate for this population. Here, we systematically examine the EQ-5D-3L (its wording, content, and format) using qualitative methods to inform the adaption of the measure for use with adults with mild to moderate learning disabilities.

METHODS

Think-aloud interviews with carers/advocates of learning-disabled adults were undertaken to explore the difficulties with completing the EQ-5D-3L. Alternative wording, language, structure, and images were developed using focus groups, stakeholder reference groups, and an expert panel. Data analysis followed a framework method.

RESULTS

The dimensions and levels within the EQ-5D-3L were deemed appropriate for adults with mild to moderate learning disabilities. Consensus on wording, structure, and images was reached through an iterative process, and an adapted version of the EQ-5D-3L was finalised.

CONCLUSION

The EQ-5D-3L adapted for adults with mild to moderate intellectual/learning disabilities can facilitate measurement of self-reported health status. Research is underway to assess the potential use of the adaptation for economic evaluation.

How Well Does the EQ-5D-Y-5L Describe Children With Intellectual Disability?: "There's a Lot More to My Child Than That She Can't Wash or Dress Herself."

OBJECTIVES

The EQ-5D-5L is a generic health utility instrument for measuring health-related quality of life (HRQoL), with self-report and proxy report versions for children (EQ-5D-Y-5L). Children with intellectual disability (ID) are a heterogeneous population whose impairments and comorbidities place them at risk of poor HRQoL. This study aimed to describe the content validity and suitability for children with ID of a proxy report version of the EQ-5D-Y-5L as seen by their caregivers.

METHODS

A proxy report EQ-5D-Y-5L was administered to caregivers of children with ID. Using cognitive think-aloud interviewing, participants were encouraged to provide the reasoning for their choices, assess the questions' relevance, comprehensibility, and comprehensiveness, and comment on the tool's strengths and weaknesses. Qualitative content analysis used both directed (deductive) and conventional (inductive) methods.

RESULTS

There were 28 interviews with 30 caregivers of children with ID (aged 8-22 years, 17 boys, with autism spectrum disorder, cerebral palsy, Down syndrome, and rare genetic disorders). The EQ-5D-Y-5L was considered clear, concise, and largely relevant, but insufficiently comprehensive for this population. Interviewees sought clarification of the definition of HRQoL, whether it included unchanging impairments (vs fluctuating health states), and what basis of comparison to use (child or peer). Many interviewees suggested inclusion of questions for other domains, including communication and social engagement, equipment and human supports required, and a wider range of mental health questions.

CONCLUSIONS

The study suggests that further work is required to ensure accurate responses to the EQ-5D-Y-5L from caregivers of children with ID and to describe these children adequately.

Using mobile health to encourage physical activity in individuals with intellectual disability: a pilot mixed methods feasibility study

Background

Many individuals with intellectual disability (ID) have a sedentary lifestyle. Few interventions aimed at increasing their level of physical activity (PA) have shown lasting effects.

Aim

To assess the feasibility and acceptability of a pilot intervention study using innovative mobile health (mHealth) support systems to encourage PA in individuals with ID.

Methods

Nine individuals with ID and a low level of PA, aged 16-36 years, were included in the present convergent triangulation mixed method design. Two mHealth support systems (apps) were developed and tested. PA was measured with a Fitbit smartwatch, accelerometer, the International Physical Activity Questionnaire-Short Form (IPAQ-S), and Goal attainment scaling. Data were collected through online pre-, mid- (4 weeks), and post-intervention (12 weeks) questionnaires and activity trackers. Semi-structured qualitative interviews with participants and/or a family or staff member were held after the 12-week follow-up. Data were analyzed using conventional nonparametric statistics and thematic analyses.

Results

The response rate and retention to the trial were 16% and 100%, respectively. Data quality was high, except for missing data from Fitbit activity trackers of approximately 30% from the 4- and 12-week follow-up stages. The feasibility challenges with activity trackers include rashes, size, non-acceptance, and loss of motivation. Participants and family members/staff reported interest in the study theme and were pleased with the data collection method. All but one participant achieved their PA goals. Most participants reported being satisfied with the apps as they were enjoyable or provided a reminder for performing physical and other activities. Social support for PA among family members also increased. However, app support from staff and family members was needed, and apps were not used regularly. Two of nine participants (22%) had increased their PA measured as steps per day with Fitbit at the 12-week follow-up.

Conclusions

The acceptability and feasibility of using tailored mobile applications in natural settings to increase PA among adults with ID are promising. This study aligns with previous studies in showing the challenges to increasing PA, which requires the inclusion of family members, staff, and stakeholders. The intervention requires modifications before a randomized controlled trial can be conducted.

Outcome measures for economic evaluations and cost-effectiveness analyses of interventions for people with intellectual disabilities: A methodological systematic review

BACKGROUND

Mainstream economic evaluations methods may not be appropriate to capture the range of effects triggered by interventions for people with intellectual disabilities. In this systematic review, we aimed to identify, assess and synthesise the arguments in the literature on how the effects of interventions for people with intellectual disabilities could be measured in economic evaluations.

METHOD

We searched for studies providing relevant arguments by running multi-database, backward, forward citation and grey literature searches. Following title/abstract and full-text screening, the arguments extracted from the included studies were summarised and qualitatively assessed in a narrative synthesis.

RESULTS

Our final analysis included three studies, with their arguments summarised in different methodological areas.

CONCLUSIONS

Based on the evidence, we suggest the use of techniques more attuned to the population with intellectual disabilities, such sensitive preference-based instruments to collect health states data, and mapping algorithms to obtain utility values.

The Development, Content Validation, and Pilot Testing of the Paraphilic Interests and Disorders Scale

The prevalence rates of paraphilic interests and disorders in the general population have been understudied, in large part due to the lack of a standardized assessment measure. As a result, the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 provides little information regarding the prevalence of paraphilic disorders. The present study involved the development of a self-report measure, Paraphilic Interests and Disorders Scale (PIDS), that can be used to assess for the eight paraphilic interests/disorders in the DSM-5 for use with general population samples. Study 1 established the content validity of the PIDS using feedback from 22 experts in the field, and recommendations from these experts were utilized to modify the measure. In Study 2, the PIDS was piloted on 100 individuals in the general population, which supported the feasibility of implementation and its limited-efficacy. While the PIDS requires further psychometric support, the current research suggests the PIDS is a promising tool to gather self-report, population-based data on DSM-5 paraphilic interests and disorders.

Multimorbidities and quality of life in adult cerebral palsy over 40 years

AIM

This study aimed to describe the most common combinations of comorbidities and their relationship to quality of life in a sample of adults over 40 years of age with cerebral palsy.

METHODS

Patients who are 40 years or older and admitted to the hospital in the last 5 years and were diagnosed with cerebral palsy were included. Demographic data and comorbidities were both questioned through the Patient Information Management System and confirmed by asking the individual about their diseases. The patients' quality of life was evaluated with the EQ-5D-3L Telephone interview version. Principal component analysis was used to determine comorbidity combinations for multiple morbidity.

RESULTS

Comorbidity was found in 72.1% of the participants and multimorbidity was found in 47.5%. The 5 most common comorbidities were musculoskeletal diseases (34.4%), psychiatric diseases (21.3%), essential hypertension (21.3%), osteoporosis (18%) and hyperlipidemia (18%). As a result of principal component analysis, a total of five components are formed and this most common comorbidity combinations in the sample explained 66.78% of the total variance.

CONCLUSIONS

New combinations of comorbidities have been demonstrated that may perhaps serve as a starting point for identifying new association of pathways. Future efforts are needed to identify modifiable factors for early intervention and prevention of chronic health problems in this population.

Cost-effectiveness analysis of extended extracorporeal membrane oxygenation duration in newborns with congenital diaphragmatic hernia in the United States

BACKGROUND

The duration of extracorporeal membrane oxygenation (ECMO) has been historically confined in many centers to two weeks. We evaluated the cost-effectiveness of additional weeks on ECMO beyond two weeks for newborns with congenital diaphragmatic hernia (CDH) who may require longer stays to maximize survival potential.

METHODS

We modeled lifetime outcomes using a decision tree from the US societal perspective. Survival at discharge, probability of long-term sequelae, direct medical costs, indirect costs, and quality-adjusted life years (QALY) for long-term disability were considered. Considering the nature of severity of CDH, we used $200,000 per QALY as the willingness-to-pay threshold in the base case.

RESULTS

The lifetime costs per CDH infant generated from staying on ECMO for ≤2 weeks, 2-3 weeks, and >3 weeks are $473,334, $654,771, $1,007,476, respectively (2018 USD), and the total QALYs gained from each treatment arm are 1.83, 3.6, and 5.05. In the base case, the net monetary benefits are -$108,034 for ECMO ≤2 weeks, $64,258 for 2-3 weeks, and $2955 for >3 weeks. In probabilistic simulations, a duration of ≤2 weeks is dominated by a duration of 2-3 weeks in 65.3% of cases and dominated by > 3 weeks in 60.2% of cases. A duration of 2-3 weeks is more cost-effective than >3 weeks in 68.6% of simulations.

CONCLUSION

Our findings suggest that 2-3 weeks of ECMO may be the most cost-effective for CDH infants that are unable to wean off at 2 weeks from the US societal perspective. Regardless of ECMO duration, ECMO use generates positive incremental NMB at WTP of $200,000 if the survival probability is greater than 0.3. Future research must be conducted to evaluate the long-term outcomes and sequelae of CDH patients post-discharge to better inform the clinical decision-making in neonatal intensive care unit.

A manualised weight management programme for adults with mild-moderate intellectual disabilities affected by excess weight: A randomised controlled feasibility trial (Shape Up-LD)

BACKGROUND

The aim was to pilot an adapted manualised weight management programme for persons with mild-moderate intellectual disabilities affected by overweight or obesity ('Shape Up-LD').

METHOD

Adults with intellectual disabilities were enrolled in a 6-month trial (3-month active intervention and 3-month follow-up) and were individually randomised to Shape Up-LD or a usual care control. Feasibility outcomes included recruitment, retention, initial effectiveness and cost.

RESULTS

Fifty people were enrolled. Follow-up rates were 78% at 3 months and 74% at 6 months. At 3 and 6 months, controlling for baseline weight, no difference was observed between groups (3 months: β: -0.34, 95% confidence interval [CI]: -2.38, 1.69, 6 months: β: -0.55, 95%CI -4.34, 3.24).

CONCLUSION

It may be possible to carry out a trial of Shape Up-LD, although barriers to recruitment, carer engagement and questionnaire completion need to be addressed, alongside refinements to the intervention.

Access to health care for older people with intellectual disability: a modelling study to explore the cost-effectiveness of health checks

Background

Whilst people with intellectual disability grow older, evidence has emerged internationally about the largely unmet health needs of this specific ageing population. Health checks have been implemented in some countries to address those health inequalities. Evaluations have focused on measuring process outcomes due to challenges measuring quality of life outcomes. In addition, the cost-effectiveness is currently unknown. As part of a national guideline for this population we sought to explore the likely cost-effectiveness of annual health checks in England.

Methods

Decision-analytical Markov modelling was used to estimate the cost-effectiveness of a strategy, in which health checks were provided for older people with intellectual disability, when compared with standard care. The approach we took was explorative. Individual models were developed for a selected range of health conditions, which had an expected high economic impact and for which sufficient evidence was available for the modelling. In each of the models, hypothetical cohorts were followed from 40 yrs. of age until death. The outcome measure was cost per quality-adjusted life-year (QALY) gained. Incremental cost-effectiveness ratios (ICER) were calculated. Costs were assessed from a health provider perspective and expressed in 2016 GBP. Costs and QALYs were discounted at 3.5%. We carried out probabilistic sensitivity analysis. Data from published studies as well as expert opinion informed parameters.

Results

Health checks led to a mean QALY gain of 0.074 (95% CI 0.072 to 0.119); and mean incremental costs of £4787 (CI 95% 4773 to 5017). For a threshold of £30,000 per QALY, health checks were not cost-effective (mean ICER £85,632; 95% CI 82,762 to 131,944). Costs of intervention needed to reduce from £258 to under £100 per year in order for health checks to be cost-effective.

Conclusion

Whilst findings need to be considered with caution as the model was exploratory in that it was based on assumptions to overcome evidence gaps, they suggest that the way health systems deliver care for vulnerable populations might need to be re-examined. The work was carried out as part of a national guideline and informed recommendations about system changes to achieve more equal health care provisions.
