Understanding Canadian stakeholders' views on measuring and valuing health for children and adolescents: a qualitative study.

OBJECTIVE: Valuing child health is critical to assessing the value of healthcare interventions for children. However, there remain important methodological and normative issues. This qualitative study aimed to understand the views of Canadian stakeholders on these issues. METHODS: Stakeholders from health technology assessment (HTA) agencies, pharmaceutical industry representatives, healthcare providers, and academic researchers/scholars were invited to attend an online interview. Semi-structured interviews were designed to focus on: (1) comparing the 3-level and 5-level versions of the EQ-5D-Y; (2) source of preferences for valuation (adults vs. children); (3) perspective of valuation tasks; and (4) methods for valuation (discrete choice experiment [DCE] and its variants versus time trade-off [TTO]). Participants were probed to consider HTA guidelines, cognitive capacity, and potential ethical concerns. All interviews were recorded and transcribed verbatim. Framework analysis with the incidence density method was used to analyze the data. RESULTS: Fifteen interviews were conducted between May and September 2022. 66.7% (N = 10) of participants had experience with economic evaluations, and 86.7% (N = 13) were parents. Eleven participants preferred the EQ-5D-Y-5L. 12 participants suggested that adolescents should be directly involved in child health valuation from their own perspective. The participants were split on the ethical concerns. Eight participants did not think that there was ethical concern. 11 participants preferred DCE to TTO. Among the DCE variants, 6 participants preferred the DCE with duration to the DCE with death. CONCLUSIONS: Most Canadian stakeholders supported eliciting the preferences of adolescents directly from their own perspective for child health valuation. DCE was preferred if adolescents are directly involved.

The use of EQ-5D-5L as a patient-reported outcome measure in evaluating community rehabilitation services in Alberta, Canada.

BACKGROUND: The purpose of this study was to describe the characteristics and health-related quality of life (HRQL) of patients accessing community rehabilitation services in Alberta, Canada, using routinely collected EQ-5D-5L data, and explore factors associated with the impact of these services. METHODS: A retrospective, longitudinal, observational design was used. Patients completed the EQ-5D-5L and demographic questions at intake and end of rehabilitation care. Change in EQ-5D-5L dimensions from intake until end of rehabilitation was examined using the Pareto Classification of Health Change. Change scores were calculated for the EQ-5D-5L index, VAS, and total sum scores. Change groups in the EQ-5D-5L index and VAS scores, were defined by minimally important differences of 0.04 and 7.0, respectively. One level change was considered important for the total sum score. Effect size of the change in index, VAS, and total sum scores was also examined. Chi-squared tests were conducted to examine whether change in EQ-5D-5L varied by age, gender, region, and having anxiety/depression at intake. RESULTS: Three service programs were examined; pulmonary rehabilitation (n = 542), group-based community exercise (n = 463), and physiotherapy for bone and joint care (n = 391). At intake, HRQL in all programs was lower than that of the general Alberta population norms and improved by end of rehabilitation. The mean (SD) change in index, VAS, and total sum scores were 0.02 (0.13), 6.0 (18.3), and - 0.5 (2.4) in pulmonary rehabilitation, 0.06 (0.13), 6.6 (18.7), - 1.2 (2.4) in community exercise, and 0.13 (0.16), 1.2 (0.9), and - 2.8 (2.8) in physiotherapy, respectively. Based on change of the index score, 24% deteriorated, 38% improved, and 38% had no change in pulmonary rehabilitation; 17% deteriorated, 51% improved, and 32% had no change in community exercise; 5% deteriorated, 72% improved, and 23% had no change in physiotherapy. Similar trends were seen in the VAS and total sum scores. Older age, urban region, and having anxiety/depression at intake were associated with positive change in EQ-5D-5L. CONCLUSIONS: The results of this study are intended to inform program/service level decisions by describing the characteristics and HRQL of patients accessing community rehabilitation, as well as the predictors of change in health status, which will help direct future program growth and service changes.

Mapping the Edmonton Symptom Assessment System-Revised: Renal to the EQ-5D-5L in patients with chronic kidney disease.

PURPOSE: The Edmonton Symptom Assessment System-Revised: Renal (ESAS-r: Renal) is a disease-specific patient-reported outcome measure (PROM) that assesses symptoms common in chronic kidney disease (CKD). There is no preference-based scoring system for the ESAS-r: Renal or a mapping algorithm to predict health utility values. We aimed to develop a mapping algorithm from the ESAS-r: Renal to the Canadian EQ-5D-5L index scores. METHODS: We used data from a multi-centre cluster randomized-controlled trial of the routine measurement and reporting of PROMs in hemodialysis units in Northern Alberta, Canada. In two arms of the trial, both the ESAS-r: Renal and the EQ-5D-5L were administered to CKD patients undergoing hemodialysis. We used data from one arm for model estimation, and data from the other for validation. We explored direct and indirect mapping models; model selection was based on statistical fit and predictive power. RESULTS: Complete data were available for 506 patient records in the estimation sample and 242 in the validation sample. All models tended to perform better in patients with good health, and worse in those with poor health. Generalized estimating equations (GEE) and generalized linear model (GLM) on selected ESAS-r: Renal items were selected as final models as they fitted the best in estimation and validation sample. CONCLUSION: When only ESAS-r: Renal data are available, one could use GEE and GLM to predict EQ-5D-5L index scores for use in economic evaluation. External validation on populations with different characteristics is warranted, especially where renal-specific symptoms are more prevalent.

Five year cost savings of a multimodal treatment program for child sexual abuse (CSA): a social return on investment study.

BACKGROUND: Specialized mental health services for the treatment of Child Sexual Abuse (CSA) are generally expensive and labour intensive. They require a trauma-informed approach that may involve multiple services and therapeutic modalities, provided over the course of several months. That said, given the broad-ranging, long term negative sequelae of CSA, an evaluation of the cost-benefit analysis of treatment is clearly justified. METHODS: We performed a Social Return on Investment (SROI) analysis of data gathered as part of the treatment program at the Be Brave Ranch in Edmonton, Canada to determine the value-for-money of the services provided. We endeavoured to take a conservative, medium-term (5 year) perspective; this is in contrast to short term (1-2 year) effects, which may rapidly dissipate, or long term (15-20 year) effects, which are likely diffuse and difficult to measure. As such, our analysis was based on an average annual intake of 100 children/adolescents (60:40 split) and their families, followed over a five-year timeframe. Financial proxies were assigned to benefits not easily monetized, and six potential domains of cost savings were identified. RESULTS: Our analyses suggest that each dollar spent in treatment results in an average cost savings of $11.60 (sensitivity analysis suggests range of 9.20-12.80). The largest value-for-money was identified as the domain of crisis prevention, via the avoidance of rare but costly events associated with the long term impacts of CSA. Somewhat surprisingly, savings related to the area of criminal justice were minimal, compared to other social domains analysed. Implications are discussed. CONCLUSIONS: Our results support the cost effectiveness of the investment associated with specialized, evidence-based early interventions for CSA. These approaches alleviate severe, negative outcomes associated with CSA, resulting in both economic savings and social benefits. These findings rest upon a number of assumptions, and generalizability of these results is therefore limited to similar programs located in comparable areas. However, the SROI ratio achieved in this analysis, in excess of $11:1, supports the idea that, while costly, these services more than pay for themselves over time.

Reducing readmission rates for individuals discharged from acute psychiatric care in Alberta using peer and text message support: Protocol for an innovative supportive program.

BACKGROUND: Individuals discharged from inpatient psychiatry units have the highest readmission rates of all hospitalized patients. These readmissions are often due to unmet need for mental health care compounded by limited human resources. Reducing the need for hospital admissions by providing alternative effective care will mitigate the strain on the healthcare system and for people with mental illnesses and their relatives. We propose implementation and evaluation of an innovative program which augments Mental Health Peer Support with an evidence-based supportive text messaging program developed using the principles of cognitive behavioral therapy. METHODS: A pragmatic stepped-wedge cluster-randomized trial, where daily supportive text messages (Text4Support) and mental health peer support are the interventions, will be employed. We anticipate recruiting 10,000 participants at the point of their discharge from 9 acute care psychiatry sites and day hospitals across four cities in Alberta. The primary outcome measure will be the number of psychiatric readmissions within 30 days of discharge. We will also evaluate implementation outcomes such as reach, acceptability, fidelity, and sustainability. Our study will be guided by the Consolidated Framework for Implementation Research, and the Reach-Effectiveness-Adoption-Implementation-Maintenance framework. Data will be extracted from administrative data, surveys, and qualitative methods. Quantitative data will be analysed using machine learning. Qualitative interviews will be transcribed and analyzed thematically using both inductive and deductive approaches. CONCLUSIONS: To our knowledge, this will be the first large-scale clinical trial to assess the impact of a daily supportive text message program with and without mental health peer support for individuals discharged from acute psychiatric care. We anticipate that the interventions will generate significant cost-savings by reducing readmissions, while improving access to quality community mental healthcare and reducing demand for acute care. It is envisaged that the results will shed light on the effectiveness, as well as contextual barriers and facilitators to implementation of automated supportive text message and mental health peer support interventions to reduce the psychological treatment and support gap for patients who have been discharged from acute psychiatric care.

Perceived changes in lifestyle behaviours and in mental health and wellbeing of elementary school children during the first COVID-19 lockdown in Canada.

OBJECTIVES: The closure of schools to prevent the spread of COVID-19 prompted concerns of deteriorating lifestyle behaviours, mental health, and wellbeing of children, particularly those in socioeconomically disadvantaged settings. We assessed changes in lifestyle behaviours (physical activity, screen time, eating habits and bed/wake-up times), mental health and wellbeing during the first lockdown in Spring 2020 as perceived by school children from disadvantaged settings, and examined determinants of these changes. STUDY DESIGN: Cross-sectional study. METHODS: We surveyed 1095 grade 4 to 6 students (age 9-12 years) from 20 schools in socioeconomically disadvantaged communities in northern Canada. Students reported on changes in lifestyle behaviours, mental health and wellbeing during the lockdown. Determinants of these perceived changes were examined in multivariable regression models. RESULTS: A majority of students reported declines in physical activity, having late bed/wake-up times, and modest improvements in mental health and wellbeing. Many students reported increases rather than decreases in screen time and snacking. Positive attitudes toward being active, eating healthy, going to sleep on time and being healthy were strongly associated with maintaining healthy lifestyle behaviours during the lockdown. Positive attitudes toward active and healthy living and healthy lifestyle behaviours were associated with maintaining positive mental health and wellbeing during the lockdown. CONCLUSIONS: The considerable changes in lifestyle behaviors, superimposed on the pre-existing burden of unhealthy lifestyle behaviours, put this generation of children at increased risk for future chronic disease. Findings call for effective health promotion of active and healthy lifestyles to benefit both physical and mental health.

The performance of the EQ-5D-3L in screening for anxiety and depressive symptoms in hospital and community settings.

BACKGROUND: To examine the performance of the EQ-5D-3L in screening for anxiety and depressive symptoms in hospital and community settings compared to other patient-reported screening tools. METHODS: Data from a prospective cohort of patients discharged from general internal medicine wards from two hospitals in Edmonton, Alberta were used in this study. Two waves of measurements (discharge and 90-days post-discharge) were analyzed. The performance of the EQ-5D-3L was compared to other self-report screening tools: Generalized Anxiety Disorder 2-item questionnaire was used to categorize anxiety symptoms into absent (< 3) and present (≥ 3), and the Patient Health Questionnaire 9-items was used to categorize depressive symptoms by two severity cut-points: no (< 10) vs. mild (≥ 10), and no (< 15) vs. moderate-severe (≥ 15). Performance of EQ-5D-3L in screening for anxiety and depressive symptoms was evaluated using receiver operating curve (ROC) analysis. RESULTS: Average age of participants (n = 493) was 62.9 years (SD 18.6); 51% were female. At discharge, 30.0% screened positive for mild and 12.8% for moderate-severe depressive symptoms, while 27.6% screened positive for anxiety symptoms. For co-morbid symptoms, 17.1% screened positive for anxiety and any depressive symptoms, while 10.8% for anxiety and moderate-severe depressive symptoms. While the EQ-5D-3L had limited screening ability in hospital, the anxiety/depression dimension performed well in the community setting (90-days post-discharge) in screening for anxiety (area under ROC 0.79), depressive symptoms (any: 0.78, moderate-severe: 0.84), and a combination of both (any: 0.86; moderate-severe: 0.91). CONCLUSIONS: The EQ-5D-3L anxiety/depression dimension could be a useful tool in screening for anxiety and depressive symptoms in community settings compared to other self-report screening tools. The usefulness of the EQ-5D-3L as a screening tool in other settings and populations is warranted.

The predictive ability of EQ-5D-3L compared to the LACE index and its association with 30-day post-hospitalization outcomes.

PURPOSE: To examine whether the EQ-5D-3L at the time of discharge from hospital provides additional prognostic information above the LACE index for 30-day post-discharge hospital readmission and to explore the association of EQ-5D-3L with readmissions, emergency department (ED) visits, and death within the same period. METHODS: Using data (n = 495; mean age 62.9 years (SD 18.6), 50.5% female) from a prospective cohort study of patients discharged from medical wards at two university hospitals, the prognostic ability of EQ-5D-3L was examined using C-statistic, Integrated Discrimination Improvement (IDI) Index, and Akaike's Information Criterion (AIC). The associations between EQ-5D-3L dimensions, total sum, index and VAS scores at the time of discharge and 30-day post-discharge ED visits, readmission, and readmission/death were examined using multivariate logistic regression. RESULTS: At the time of discharge, 58.6% of participants reported problems in mobility, 28.3% in self-care, 62.1% in usual activities, 62.7% in pain/discomfort, and 42.4% in anxiety/depression. Mean (SD) total sum score was 7.9 (2.0), index score was 0.69 (0.21), and VAS score was 63.7 (18.4). In adjusted analyses, mobility, self-care, usual activities, and the total sum score were significantly associated with 30-day readmission and readmission/death. Differences in C-statistic for LACE readmission prediction models with and without EQ-5D-3L were small. AIC analysis suggests that readmission prediction models containing EQ-5D-3L dimensions or scores were more often preferred to those with the LACE index only. IDI analysis indicates that the discrimination slope of readmission prediction models is significantly improved with the addition of mobility, self-care, or the total sum score of the EQ-5D-3L. CONCLUSION: The EQ-5D-3L, especially the mobility and self-care dimensions as well as the total sum score, improves 30-day readmission prediction of the LACE index and is associated with 30-day readmissions or readmissions/death.

Cost-effectiveness and return on investment of school-based health promotion programmes for chronic disease prevention.

BACKGROUND: While school-based health prevention programmes are effective in addressing unhealthy diet and physical inactivity, little is known about their economic implications. We conducted an economic evaluation of the programmes that were previously identified as feasible, acceptable, and sustainable in the Canadian context. METHODS: This study builds on a meta-analysis of the effectiveness of feasible, acceptable, and sustainable school-based health promotion programmes. A micro-simulation model incorporated intervention effects on multiple risk factors to estimate incremental cost-effectiveness and return on investment (ROI) of comprehensive school health (CSH), multicomponent, and physical education (PE) curriculum modification programmes. Cost-effectiveness was expressed as the programme costs below which the programme would be cost-effective at a CA$50 000 threshold level. RESULTS: The estimated costs below which interventions were cost-effective per quality-adjusted life year gained were CA$682, CA$444, and CA$416 per student for CSH, multicomponent, and PE curriculum modification programmes, respectively. CSH programmes remained cost-effective per year of chronic disease prevented for costs of up to CA$3384 per student, compared to CA$1911 and CA$1987 for multicomponent and PE curriculum modification interventions, respectively. If the interventions were implemented at total discounted intervention costs of CA$100 per student, ROI through the avoidance of direct healthcare costs related to the treatment and management of chronic diseases would be 824% for CSH, 465% for multicomponent interventions, and 484% for PE curriculum modification interventions. CONCLUSIONS: Whereas each examined intervention types showed favourable economic benefits, CSH programmes appeared to be the most cost-effective and to have the highest ROI.

Adherence to Life-Style Recommendations and Attention-Deficit/Hyperactivity Disorder: A Population-Based Study of Children Aged 10 to 11 Years.

OBJECTIVE: The incidence of attention-deficit/hyperactivity disorder (ADHD) among children and youth is high, and temporal increases have been paralleled by deteriorating life-styles. Poor diet quality, physical inactivity, poor sleep habits, and sedentary behaviors have all been associated with ADHD. However, no earlier prospective study has examined the independent and combined importance of meeting established life-style recommendations in childhood for ADHD in adolescence. We examined the associations of adherence to life-style recommendations with the incidence of ADHD and the utilization of health services associated with ADHD. METHODS: Life-style survey among 10- and 11-year-old students (N = 3436) was linked to administrative health data. Associations between adherence to nine established life-style recommendations with ADHD diagnosis and number of physician visits for ADHD until age 14 years were examined using Cox proportional hazard and negative binomial regression. RESULTS: Before age 14 years, 10.8% of students received an ADHD diagnosis. Meeting recommendations for vegetables and fruit, meat and alternatives, saturated fat, added sugar, and physical activity was associated with fewer ADHD diagnoses. Compared with children who met one to three recommendations, meeting seven to nine recommendations was associated with substantially lower incidence of ADHD and fewer physician visits related to ADHD (hazard ratio = 0.42 [95% confidence interval = 0.28-0.61]; rate ratio = 0.38 [95% confidence interval = 0.22-0.65]). CONCLUSIONS: Life-style recommendations exist to benefit development and physical health. Their promotion comes at no harm and may have benefits for ADHD. Experimental evidence is needed to clarify the potential bidirectional relationship between ADHD and adverse health behaviors.

Added, free and total sugar content and consumption of foods and beverages in Canada.

BACKGROUND: Consumption of sugars contributes to obesity and various chronic diseases. The U.S. Department of Agriculture and the World Health Organization recommend that added and free sugar consumption be less than 10% of total energy intake (TEI). However, in Canada, the added and free sugar content of foods and beverages is not documented, so Canadians' consumption and compliance with the above recommendations are unknown. DATA AND METHODS: This study calculated the added and free sugar content of all 5,374 foods and beverages recorded in the 24-hour dietary recalls of the 2015 Canadian Community Health Survey - Nutrition using established procedures. The usual intake of added, free and total sugars was estimated with the National Cancer Institute method. RESULTS: In 2015, residents of Canada consumed an average of 57.1 g/day of added sugars, 67.1 g/day of free sugars and 105.6 g/day of total sugars. This represented 11.1%, 13.3% and 21.6% of TEI for added, free and total sugar intake, respectively. Among all Canadians, 49.0% consumed less than 10% of TEI from added sugars, while 33.8% consumed less than 10% of TEI from free sugars. The food groups with the highest added and free sugar content were desserts and sweets, breakfast cereals, baked products, beverages, and snacks. Desserts and sweets and beverages were the two main contributors of sugar in the Canadian diet. DISCUSSION: The majority of Canadians consumed more added and free sugars than recommended. Estimating added and free sugar content and consumption could help researchers assess the health of Canadians and the economic burden of excessive sugar consumption and could help policy makers articulate intervention targets.

Discriminative validity of the EQ-5D-5 L and SF-12 in older adults with arthritis.

BACKGROUND: The EQ-5D-5 L and the SF-12 are the most commonly used generic measures of health-related quality of life among people with arthritis. However, there is little evidence on the extent to which the individual dimensions and domains of these instruments perform among this population. The objective was to examine the discriminative validity of the EQ-5D-5 L and the SF-12 version 2 (and SF-6D) in capturing the burden of arthritis on health-related quality of life in older adults. METHODS: Cross-sectional data from the Alberta Retired Teachers Association survey were used. A known-groups approach, with a-priori hypotheses, was used to examine the discriminative validity of the domain and summary scores of the EQ-5D-5 L and the SF-12 version 2 (and SF-6D). Groups were defined based on self-reported of arthritis, chronic pain level, presence and number of comorbidities, and self-reported health status. RESULTS: Mean age of respondents (N = 2844) was 68.6 (standard deviation [SD] 5.9) years; 54.8% were female, with mean body mass index (BMI) of 27.2 kg/m2 (SD 4.8), and 36.6% reported having arthritis. The overall mean EQ-5D-5 L index score was 0.86 (SD 0.11) and that of SF-6D was 0.79 (SD 0.13). Participants with arthritis had lower EQ-5D-5 L index score (0.83, SD 0.13) and SF-6D index score (0.75, SD 0.13) compared to those without arthritis (0.88, SD 0.09 and 0.81, SD 0.12, respectively). EQ-5D-5 L and SF-6D index scores demonstrated moderate discriminative validity with a moderate effect size (0.5). Related dimensions and domains between the EQ-5D-5 L and SF-12 (e.g., mobility with physical functioning score, pain/discomfort with bodily pain and anxiety/depression with mental health) were moderately to strongly correlated (r = 0.6-0.7). Both instruments could not adequately discriminate between participants with moderate and severe chronic pain of 6-month duration. CONCLUSION: Overall, the EQ-5D-5 L pain/discomfort and mobility dimensions, and the SF-12 bodily pain scale had moderate discriminative ability among older adults with arthritis. However, both instruments had limited discriminative ability for chronic pain. The importance and nature of chronic pain assessment in a given application need to be considered when choosing any of these instruments for measuring health-related quality of life in this patient population.

The relationship between individual-level deprivation and health-related quality of life.

OBJECTIVE: To examine the association between individual-level deprivation and health-related quality of life (HRQL) in the general population. METHODS: Data from a population-based survey in the Canadian province of Alberta were used. Individual-level deprivation was assessed using the Canadian Deprivation Index (CDI) and the Ontario Deprivation Index (ODI). HRQL was assessed using the EQ-5D-5 L. Differences in problems in the EQ-5D-5 L dimensions, index and visual analogue scale (VAS) scores across levels of deprivation were examined. Multivariate logistic and linear regression models adjusted for socio-demographic and other characteristics were used to examine the independent association between deprivation and HRQL. RESULTS: Of the 6314 respondents, 39% were aged between 18 and 44 years and 38% between 45 and 64 years; 60% were female. Mean EQ-5D-5 L index and VAS scores were 0.85 (standard deviation [SD] 0.14) and 79.6 (SD 17.7), respectively. Almost one-third (30.6%) of respondents reported no problems on all EQ-5D-5 L dimensions. Few participants reported some problems with mobility (23.8%), self-care (6.2%) and usual activities (25.2%), while 59.3 and 35.5% reported some levels of pain/discomfort and anxiety/depression, respectively. Differences between the most and least deprived in reporting problems in EQ-5D-5 L dimensions, index and VAS scores were statistically significant and clinically important. In adjusted regression models for both deprivation indices, the least well-off, compared to the most well-off, had higher likelihood of reporting problems in all EQ-5D-5 L dimensions. Compared to the most well-off, the least well-off had an EQ-5D-5 L index score decrement of 0.18 (p < 0.01) and 0.17 (p < 0.01) for the CDI and ODI, respectively. Similarly, an inverse association was found between the VAS score and the CDI (ß = - 17.3, p < 0.01) as well as the ODI (ß = - 13.3, p < 0.01). CONCLUSION: Individual-level deprivation is associated with worse HRQL. Poverty reduction strategies should consider the effects of not only neighbourhood-level deprivation, but also that of individual-level deprivation to improve overall health.

Responsiveness of the EQ-5D-3L and EQ-5D-5L in patients following total hip or knee replacement.

PURPOSE: To examine the responsiveness of the EQ-5D-3L and EQ-5D-5L among total hip/knee replacement (THR/TKR) patients. METHODS: The EQ-5D (3L or 5L) and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) have been routinely administered to all THR/TKR patients before and at 3 months after surgery in Alberta, Canada, since 2010. Patients were included in this analysis if they completed the WOMAC and the same version of EQ-5D at baseline and 3-month follow-up. The WOMAC was used as an anchor to categorize patients into 9 subgroups according to the relative change from baseline, i.e., no change, and 4 categories each for the amount of deterioration or improvement: large (≥ 70%), moderate (50% ≤ change < 70%), small but important (20% ≤ change < 50%), and very mild (0 < change ≤ 20%). The responsiveness of the EQ-5D-3L and EQ-5D-5L for each subgroup was assessed using effect size, standardized response mean, and Guyatt's Responsiveness Index. RESULTS: A total of 1594 patients completed the EQ-5D-3L and WOMAC (60% females, mean age 66 years, N = 646 [41%] THR), and 3180 completed the EQ-5D-5L and WOMAC (60% females, mean age 66 years, N = 1352 [43.2%] THR) at baseline and 3-month follow-up. For both THR and TKR patients with "small but important" improvement, the EQ-5D-5L was consistently more responsive than the EQ-5D-3L. CONCLUSION: Our study demonstrated that the EQ-5D-5L is more responsive than the EQ-5D-3L in identifying health-related quality of life changes in THR/TKR patients. We recommend using the EQ-5D-5L in longitudinal studies in this patient population.

The influence of diet quality and dietary behavior on health-related quality of life in the general population of children and adolescents: a systematic review and meta-analysis.

OBJECTIVE: The association between diet quality, dietary behavior and health-related quality of life has been mostly examined in children and adolescents with specific chronic diseases. No systematic review has synthesized the influence of diet quality and dietary behavior on health-related quality of life in the general population of children and adolescents. The purpose of this study was to systematically review the primary studies that evaluated the association between diet quality, dietary behavior and health-related quality of life in the general population of children and adolescents and to synthesize the findings for the association. METHODS: A computer search in the databases of MEDLINE, EMBASE and PSYCINFO was performed to retrieve English language studies that were published from 1946 up to April 8, 2018. We also screened the PubMed-related articles and the reference lists of the existing relevant literature to identify other eligible studies. We synthesized the association between diet quality, dietary behavior and health-related quality of life using both a qualitative method and meta-analysis. We reported the review following up the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guideline. RESULTS: Seventeen studies were included in the synthesis including twelve cross-sectional studies and five longitudinal studies. We found that diet quality and dietary behavior were associated with health-related quality of life in children and adolescents. The positive effect of healthy diets on health-related quality of life was observed for multiple domains of health-related quality of life, including physical, school and emotional functioning, and psychosocial quality of life. We observed a dose-response relationship between the diet exposure and health-related quality of life, where an unhealthy dietary behavior or lower diet quality was associated with decreased health-related quality of life among children and adolescents. CONCLUSION: The findings of the systematic review suggest the importance of promoting healthy diets and nutrition for good health-related quality of life among children and adolescents. Future research is needed to strengthen the evidence for prospective relationships and for the dose-response effect between diet quality, dietary behavior and health-related quality of life among children and adolescents.

The EQ-5D-5L Is Superior to the -3L Version in Measuring Health-related Quality of Life in Patients Awaiting THA or TKA.

BACKGROUND: As a generic measure of health-related quality of life among patients awaiting THA or TKA, the three-level version of the EQ-5D (EQ-5D-3L), which has three response levels of severity (no problems, some problems, and extreme problems/unable) to five questions, is widely used. Previous studies indicated that the ceiling effect of the EQ-5D-3L limits its application. The five-level version of the EQ-5D (EQ-5D-5L) was developed to enhance the measurement properties of the tool by adding two levels: slight problems and severe problems. However, only a few small studies have compared the EQ-5D-3L and EQ-5D-5L in patients awaiting THA and TKA. QUESTIONS/PURPOSES: The purpose of this study was to examine the performance of the EQ-5D-3L and EQ-5D-5L among patients awaiting THA or TKA in terms of (1) response patterns, (2) convergent construct validity, (3) known-group validity, and (4) informativity and discriminatory power. METHODS: This is a retrospective analysis of the Alberta Bone and Joint Health Data Repository, which recorded information on all patients receiving hip or knee arthroplasties between April 2010 and March 2017 in Alberta, Canada (n = 37,377). Patients receiving THA or TKA and who completed the EQ-5D and WOMAC at baseline (presurgery) were included in this study (n = 24,766). The EQ-5D-3L was administered to all patients in 2010, and was gradually replaced by the EQ-5D-5L between 2013 and 2016; the EQ-5D-5L reached full application in all clinics by 2017.A propensity score was used to match patients 1:1 who completed either the EQ-5D-3L or EQ-5D-5L before surgery. Response patterns have been explored using ceiling and floor effects and distribution across severity levels of each dimension. Convergent construct validity was examined using Spearman's correlation (rho) against the WOMAC. Known-group validity was examined by gender, preoperative risk factors, mental health, obesity, and WOMAC physical function score. Informativity and discriminatory power were examined using the Shannon (H') and Shannon evenness (J') indices. A total of 3446 pairs of patients awaiting THA (55% women; mean age, 66 years) and 5428 pairs of patients awaiting TKA (59% women; mean age 67 years) were included in this analysis; the study group included all patients who were kept in the propensity score matching. RESULTS: Ceiling and floor effects were comparable and small (less than 0.5%) for both versions; the responses across severity levels for each dimension were more evenly distributed for the EQ-5D-5L. Convergent construct validity was stronger for the EQ-5D-5L as it consistently had stronger correlations with the WOMAC overall and domain scores than the EQ-5D-3L (rho(3L-THA), -0.77 to -0.31; rho(3L-TKA), -0.71 to -0.24; rho(5L-THA), -0.71 to -0.17; rho(5L-TKA), -0.64 to -0.17; all p values < 0.001). The hypotheses of known-group analyses were confirmed for both versions. The EQ-5D-5L demonstrated stronger informativity and discriminatory power than the EQ-5D-3L, particularly for the mobility dimension (THA, H'(5L/3L)=1.66/0.37, J'(5L/3L)=0.72/0.23; TKA, H'(5L/3L)=1.66/0.41, J'(5L/3L)=0.71/0.26). CONCLUSIONS: This study demonstrates the superior construct validity, and informativity and discriminatory power of the EQ-5D-5L compared with the EQ-5D-3L among patients awaiting THA or TKA. CLINICAL RELEVANCE: Compared with the three-level version, the five-level version of the EQ-5D differentiates between patients awaiting THA and TKA much better based on their mobility, which is a key health aspect or outcome in these patients. Our findings suggest that the EQ-5D-5L is more appropriate for this population.

Minimally Important Difference of the EQ-5D-5L Index Score in Adults with Type 2 Diabetes.

BACKGROUND: The EuroQol five-dimensional questionnaire (EQ-5D) is a generic preference-based measure of health-related quality of life, and several studies have made attempts to estimate the minimally important difference (MID) for the EQ-5D index score. OBJECTIVES: To estimate the MID of the five-level EQ-5D (EQ-5D-5L) index score in a population-based sample of adults with type 2 diabetes and to explore whether the MID estimate varies by baseline index score and the direction of change in health status. METHODS: We used longitudinal survey data of adults with type 2 diabetes in Alberta, Canada. The EQ-5D-5L MID was estimated first by the instrument-defined approach, which used the difference between the baseline index scores and the index scores of simulated single-level transitions, and then by the anchor-based approach, which categorized 1-year changes in depressive symptoms, diabetes-related distress, as well as physical and mental health functioning into no change, small change, and large change groups, wherein the MID was estimated as the average change in index score of the small change group. RESULTS: Using the instrument-defined approach, MID estimates were 0.043, 0.040, and 0.045, whereas anchor-based MID estimates were 0.042, 0.034, and 0.049 for all change, improvement, and deterioration, respectively. Larger MID estimates were observed for lower baseline index scores and for deterioration in health status. CONCLUSIONS: MID estimates of the EQ-5D-5L index score were consistent between instrument-defined and anchor-based approaches and ranged between 0.03 and 0.05. Estimates varied by baseline index score and the direction of change, with similar results for patient subgroups.

Responsiveness of the anxiety/depression dimension of the 3- and 5-level versions of the EQ-5D in assessing mental health.

BACKGROUND: Anxiety and depression disorders are associated with significantly lower health-related quality of life (HRQL). The EQ-5D is a commonly used generic measure of HRQL; it captures mental health through a single domain-the anxiety/depression dimension. Evidence on the responsiveness of this measure in assessing changes in mental health changes is limited. OBJECTIVE: To examine the performance of the anxiety/depression dimension (A/D) of the 3- and 5-level (3L and 5L) versions of the EQ-5D in assessing changes in mental health. METHODS: Data from two patient populations were used: 495 adults post-discharge from general internal medicine ward (EQ-5D-3L), and 225 type 2 diabetes patients who screened positive for depressive symptoms (EQ-5D-5L). Anchor-based approach along with effect sizes (ES) and ROC analysis was used. Anchors included patient health questionnaire 9-items "PHQ9" and generalized anxiety disorder 2-item questionnaire "GAD2" for EQ-5D-3L, and PHQ9 and SF-12 mental composite summary scores (MCS) for EQ-5D-5L. A/D change was quantified as the difference between follow-up and baseline levels. RESULTS: The A/D dimension of the EQ-5D-3L showed limited responsiveness to changes in depressive symptoms measured by PHQ9 and for anxiety symptoms measured by GAD2, whereby in those who improved or deteriorated in either symptom, more than half of the patients did not have an A/D change. In the ROC analysis, the A/D dimension of the EQ-5D-3L showed weak performance with C-indices ranging from 0.58 to 0.63 and probability of detection of depressive or anxiety symptoms ranging between 20 and 40%, which are all well below acceptable ranges. Similar results were observed for the A/D dimension of the EQ-5D-5L; although the performance was slightly better, it was still below acceptable range. In patients who improved or deteriorated based on the PHQ9 or MCS, around a third had no changes on the A/D dimension. The performance of the A/D dimension of the EQ-5D-5L was also very limited with C-indices ranging between 0.67 and 0.76, and probability of detection between 50 and 67%, slightly better than that of the 3L, yet unsatisfactory. CONCLUSIONS: Although the A/D of both EQ-5D-3L and 5L was limited in capturing changes in mental health in these populations, the 5L was slightly more responsive than the 3L. While the performance was better for depressive than anxiety symptoms, it varied by the direction of change. Further research using other measures of mental health in other populations is warranted.

The relationship of neighbourhood-level material and social deprivation with health-related quality of life.

PURPOSE: To examine the relationship of neighbourhood-level material and social deprivation with health-related quality of life, measured by the EQ-5D-5L, in the general adult population. METHODS: A sample of 11,835 adults living in Alberta, Canada was drawn from three combined annual Health Quality Council of Alberta Satisfaction and Experiences with Health Care Services surveys from 2012 to 2016. Neighbourhood-level material and social deprivation indices were derived using the Pampalon index and the 2006 Canadian census. The EQ-5D-5L dimensions, index and VAS scores were compared across the deprivation indices quintiles in the overall sample and by participants' sub-groups. Differences were tested using ANOVA or Chi-square test as appropriate. Multivariate linear regression models were conducted to examine the independent association of material and social deprivation with the EQ-5D-5L index and VAS scores, and multinomial logistic regression models with each of the EQ-5D-5L dimensions. RESULTS: Respondents in higher material or social deprivation categories had lower EQ-5D-5L index and VAS scores than those in the least deprived categories. Additionally, respondents with higher material deprivation were more likely to report problems on mobility, usual activities, and pain/discomfort; those with higher social deprivation were more likely to report problems on mobility, self-care, usual activities, and anxiety/depression. CONCLUSION: Higher neighbourhood-level material and social deprivation is significantly associated with lower health-related quality of life in the general adult population. Examining the factors leading to this inequity in health between individuals living in the least and most deprived neighbourhoods is imperative to mitigating these inequities.

Public Expenditures for Mental Health Services in Canadian Provinces: Dépenses publiques pour les services de santé mentale dans les provinces canadiennes.

OBJECTIVE: The purpose of this study is to measure provincial spending for mental health services in fiscal year (FY) 2013 and to compare these cost estimates to those of FY 2003. METHODS: This study estimated the costs of publicly funded provincial mental health services in FY 2013 and compared them to the estimates for FY 2003 from a previously published report. Our data were obtained from publicly accessible databases. The cross-year cost comparisons for provincial mental health services were restricted to general and psychiatric hospital inpatients, clinical payments to physicians and psychologists, and prescribed psychotropic medications. Total public expenditures were inflation adjusted and expressed per capita and as a percentage of the total provincial health spending. RESULTS: Total public spending for mental health and addiction programs/services was estimated to be $6.75 billion for FY 2013. The largest component of the expenditures was hospital inpatient services ($4.02 billion, 59.6%), followed by clinical payments to physicians or psychologists ($1.69 billion, 25%), and then publicly funded prescribed psychotherapeutic medications ($1.04 billion, 15.4%). Nationally, the portion of total public spending on health that was spent on mental health decreased from FY 2003 to FY 2013 from 5.4% to 4.9%. CONCLUSION: Our results reveal that mental health spending, as a proportion of public health care expenditures, decreased in the decade from FY 2003 to FY 2013. Due to large differences in how the provinces report community mental health services, we still lack a comprehensive picture of the mental health system.
