The relationship among Mental Health Status (GHQ-12), Health Related Quality of Life (EQ-5D) and Health-State Utilities in a general population

A Comparison of Items and Constructs of Standardized Health-Related Quality of Life and Mental Well-Being Measures

OBJECTIVES

This study aimed to explore the internal constructs of the concepts being measured by EQ-5D-5L (a health-related quality of life measure that can produce preference-based utility values) and the 12-item General Health Questionnaire (GHQ-12, a mental well-being measure) and to understand to what extent the items of EQ-5D-5L and GHQ-12 associate with each other.

METHODS

We used data from 12 701 respondents participating in a Belgian survey in 2022. Correlation coefficients between GHQ-12 and EQ-5D-5L were calculated at both the aggregate and item levels. Multidimensional scaling, exploratory factor analysis, and regression models were performed to investigate the underlying constructs that are associated with the items.

RESULTS

Despite a moderate correlation (0.39) between the EQ-5D-5L and GHQ-12 total scores, only a trivial or weak correlation (<0.3) was observed between the first 4 EQ-5D-5L items and any GHQ-12 item. Multidimensional scaling and exploratory factor analysis showed the first 4 EQ-5D-5L dimensions were clustered together with EuroQol visual analog scale and positively phrased GHQ-12 items were close to each other, whereas EQ-anxiety/depression and negatively phrased GHQ-12 items were grouped with overall life satisfaction. In the regression models, not all GHQ-12 items had a significant coefficient to predict EQ-5D-5L responses.

CONCLUSIONS

To the best of our knowledge, we present the first comparison of items and underlying constructs of GHQ-12 and EQ-5D-5L. The results showed that GHQ-12 can only partially predict the responses of EQ-5D-5L and the 2 instruments measure different constructs. Researchers should carefully consider conceptual legitimacy while applying the mapping technique and consider sensitivity analyses for the mapping estimates.

A Systematic Review of Methods Used by Pediatric Cost-Utility Analyses to Include Family Spillover Effects

BACKGROUND

A child's health condition affects family members' health and well-being. However, pediatric cost-utility analysis (CUA) commonly ignores these family spillover effects leading to an incomplete understanding of the cost and benefits of a child's health intervention. Methodological challenges exist in assessing, valuing, and incorporating family spillover effects.

OBJECTIVE

This study systematically reviews and compare methods used to include family spillover effects in pediatric CUAs.

METHODS

A literature search was conducted in MEDLINE, Embase, EconLit, Cochrane collection, CINAHL, INAHTA, and the Pediatric Economic Database Evaluation (PEDE) database from inception to 2020 to identify pediatric CUAs that included family spillover effects. The search was updated to 2021 using PEDE. The data describing in which family members spillover effects were measured, and how family spillover effects were measured, incorporated, and reported, were extracted. Common approaches were grouped conceptually. Further, this review identified theories or theoretical frameworks used to justify approaches for integrating family spillover effects into CUA.

RESULTS

Of 878 pediatric CUAs identified, 35 included family spillover effects. Most pediatric CUAs considered family spillover effects on one family member. Pediatric CUAs reported eight different approaches to measure the family spillover effects. The most common method was measuring the quality-adjusted life years (QALY) loss of the caregiver(s) or parent(s) due to a child's illness or disability using an isolated approach whereby family spillover effects were quantified in individual family members separately from other health effects. Studies used four approaches to integrate family spillover effects into CUA. The most common method was to sum children's and parents/caregivers' QALYs. Only two studies used a theoretical framework for incorporation of family spillover effects.

CONCLUSIONS

Few pediatric CUAs included family spillover effects and the observed variation indicated no consensus among researchers on how family spillover effects should be measured and incorporated. This heterogeneity is mirrored by a lack of practical guidelines by Health Technology Assessment (HTA) agencies or a theoretical foundation for including family spillover effects in pediatric CUA. The results from this review may encourage researchers to develop a theoretical framework and HTA agencies to develop guidelines for including family spillover effects. Such guidance may lead to more rigorous and standardized methods for including family spillover effects and better-quality evidence to inform decision-makers on the cost-effectiveness of pediatric health interventions.

Influence of immigrant background on the outcome of total hip arthroplasty: better outcome in 280 native patients in Bosnia and Herzegovina than in 449 immigrants living in Sweden

BACKGROUND

Despite the overall success of THA, between 5 and 20% report unsatisfactory results. Several factors may cause this variable outcome. 1 of them might be ethnicity which, because of its potential social impact on living conditions, may influence quality of life too. It should be studied whether patients born and being operated in their home country Bosnia and Herzegovina (BH) had similar results as immigrants being operated in Sweden (IS).

METHODS

Data of 280 patients were collected prospectively from questionnaires in the BH group. Patients of the IS group were eligible if both of their parents were born outside the Nordic countries, not having Swedish as their native language. Data were gained from the Swedish Arthroplasty Registry (SAR), 449 patients were included. Outcomes were pain VAS, satisfaction VAS, EQ-VAS, and the EQ-5D. Logistic and linear regression models including age, sex, diagnosis, type of fixation, surgical incision, marital status and educational level were analysed to compare those 2 groups.

RESULTS

There were considerable differences in patient demographics between the 2 groups. Before the operation, patients in the BH group reported more problems with self-care and usual activities, even after adjustment for confounding factors (p < 0.0005). Patients in the IS group reported a higher EQ-VAS and more pain VAS (p < 0.0005), the difference in the EQ-VAS was not significant after adjustment for confounding factors (p = 0.41). After 1 year patients in the BH group reported better scores in all dimensions of the EQ-5D (p ⩽ 0.005) apart from self-care. After adjustment for confounding factors, patients in the BH group were more satisfied too (p < 0.0005).

CONCLUSIONS

Immigrated patients (IS group) seemed to experience less benefit from THA 1 year after the operation despite more symptoms preoperatively. There were considerable limitations affecting the results. Nevertheless, the data are a point of concern, and it is suggested to take more multidimensional care of immigrant patients.

An Item-Response Mapping from General Health Questionnaire Responses to EQ-5D-3L Using a General Population Sample from England

BACKGROUND

The 12-item General Health Questionnaire (GHQ-12) is widely used to measure mental health and well-being; however, it is not possible to estimate values on the full health = 1, dead = 0 scale used to construct quality-adjusted life-years (QALYs) from GHQ-12 responses as it is not preference-based.

OBJECTIVE

The aim of this study was to create an item-response mapping between GHQ-12 and EQ-5D-3L health states, for which several value sets exist.

METHODS

Data from the 2012 Health Survey for England with complete GHQ-12 and EQ-5D-3L descriptive system responses were used for analysis. Data were split 70/30 into estimation/test samples. Four modelling approaches, with EQ-5D-3L levels on each dimension as dependent variables and GHQ-12 responses as independent variables were assessed: non-parametric, simple ordered logit (OL), extended OL, and least absolute shrinkage and selection operator (LASSO). Approaches were assessed using Akaike and Bayesian information criteria, predictive accuracy measured using root mean squared error (RMSE), and simplicity.

RESULTS

A total of 8114 responses became 6924 after discarding missing values, with 4847 used in estimation and 2077 used for testing. LASSO had a better model fit on the pain/discomfort dimension, but no model had markedly superior predictive accuracy. The non-parametric approach was chosen for the mapping algorithm based on simplicity. Predicted and observed EQ-5D-3L values for the test sample had a correlation of 0.488. Prediction accuracy was better for GHQ-12 scores below 20 than scores above 20.

CONCLUSION

The mapping allows EQ-5D-3L responses to be predicted using GHQ-12 responses, which may be useful in estimating utility values and QALYs. An R script and Microsoft Excel spreadsheet are provided to facilitate calculations.

General Health Questionnaire (GHQ12): new evidence of construct validity

This study aimed to gather evidence on the adequacy of the General Health Questionnaire (GHQ-12) in Brazil, considering a random sample of Brazilian physicians. Specifically aimed: (1) to test the GHQ-12 bifactor structure compared to alternative models, (2) to check its factorial invariance regarding to gender and the diagnosis of mental and behavioral disorders, and (3) to know the association of this measure with indicators of poor health (e.g., suicidal thoughts, decreased libido, medication use). The study included 1,085 physicians with a mean age of 45.7 (SD = 10.6), mostly male (61.5%), married (72.6%) and Catholic (59.2%). They answered the GHQ-12, the Positive and Negative Suicidal Ideation Inventory, and demographic questions. The best fit model was the bifactor structure composed of anxiety and depression, in addition to a general dimension, which presented Cronbach's alpha, McDonald's ω and composite reliability higher than 0.70 just for a general fact. Psychological distress scores correlated with suicidal ideation and indicators of health and sexual satisfaction. This is a psychometrically suitable instrument that can be used in terms of its total, but its specific factors need to be used with caution.

Sociodemographic and Clinical Characteristics Associated with Improvements in Quality of Life for Participants with Opioid Use Disorder

Background: The Houston Emergency Opioid Engagement System was established to create an access pathway into long-term recovery for individuals with opioid use disorder. The program determines effectiveness across multiple dimensions, one of which is by measuring the participant’s reported quality of life (QoL) at the beginning of the program and at successive intervals. Methods: A visual analog scale was used to measure the change in QoL among participants after joining the program. We then identified sociodemographic and clinical characteristics associated with changes in QoL. Results: 71% of the participants (n = 494) experienced an increase in their QoL scores, with an average improvement of 15.8 ± 29 points out of a hundred. We identified 10 factors associated with a significant change in QoL. Participants who relapsed during treatment experienced minor increases in QoL, and participants who attended professional counseling experienced the largest increases in QoL compared with those who did not. Conclusions: Insight into significant factors associated with increases in QoL may inform programs on areas of focus. The inclusion of counseling and other services that address factors such as psychological distress were found to increase participants’ QoL and success in recovery.

How different domains of quality of life are associated with latent dimensions of mental health measured by GHQ-12

BACKGROUND AND OBJECTIVES

A short form of the General Health Questionnaire (GHQ-12) is a useful screening instrument for assessing mental health. Furthermore, Quality of life (QoL) is a critical treatment outcome in many clinical and health care research settings. This study aimed to reassess the dimensionality of GHQ-12 using Multidimensional Graded Response Model (MGRM) and evaluate how its extracted dimensions are associated with the QoL's domains.

METHODS

Isfahan Cohort Study 2 (ICS2) is a population-based, ongoing prospective cohort study among adults aged 35 years and older who were free of cardiovascular diseases (CVDs) at the beginning of the study in 2013. A total of 1316 participants, all living in urban and rural areas of Isfahan and Najafabad, Iran was completed the GHQ-12 and WHO QoL-brief version at baseline. Five competing MGRMs with different latent structures were specified for GHQ-12. Factor scores derived from the best fitted model were used to associate with various domains of QoL.

RESULTS

The Three-Dimensional model for GHQ-12 was the best-fitted model explaining the Social Function (SF), Self Confidence (SC), and Anxiety/Depression (A/D) as three correlated yet different latent dimensions of mental health. Our findings in full adjusted multivariate regression models showed that a one-SD increase in dimensions of SC and SF was associated with a 38- to 48%-SD and 27- to 38%-SD increase in the domains scores of QoL, respectively. Moreover, for each one-SD increase in score of A/D dimension, the domains scores of QoL decreased by 29- to 40%-SD. The highest to the lowest standardized coefficients for all latent dimensions of mental health were respectively related to the psychological, physical health, social relationships, and environmental condition domains of QoL. Furthermore, SC, A/D, and SF dimensions of GHQ-12 showed the highest to the lowest degree of association with all domains of QoL.

CONCLUSIONS

Our findings confirm that the GHQ-12 as a multidimensional rather than unitary instrument measures distinct dimensions of mental health. Furthermore, all aspects of QoL changed when the intensity of latent dimensions of mental health increased. Moreover, the psychological domain of QoL is the most affected by all latent dimensions of mental health, followed by physical health, social relationships, and environmental condition domains. It seems that in an attempt to full recovery as assessed by improved QoL outcomes, treatment of clinical symptoms may not be sufficient. Identifying and differentiating the structures of mental health in each community as well as implementing intervention programs aimed at focusing on specific dimensions may help in the prevention of further deterioration of mental health and improved QoL in the community.

Burnout, Mental Health, and Quality of Life Among Employees of a Malaysian Hospital: A Cross-sectional Study

Burnout and mental health issues are common among healthcare workers. Burnout and mental ill-health may also adversely affect quality of life (QOL). This study aimed to determine the prevalence of burnout, mental ill-health, and QOL among employees of Hospital Bentong in Pahang state, Malaysia. This was a 2-week, cross-sectional online survey for Hospital Bentong employees. It consisted of (i) sociodemographic data, (ii) respondents’ perceptions, (iii) Malay-version Copenhagen Burnout Inventory (CBI), (iv) 21-item Depression, Anxiety and Stress scale (DASS-21), and (v) WHO Quality of Life-BREF (WHOQOL-BREF) instrument. In total, 52.4% of hospital employees (N = 251) participated in the study. The burnout rates were 17.5% (personal burnout), 13.9% (work burnout), and 6.0% (client burnout). The prevalence rates of depression, anxiety, and stress were 18.7, 38.6, and 12.0%, respectively. In multivariate regression analysis, personal burnout was associated with Malay ethnicity [odds ratio (OR) = 4.54, 95% confidence interval (CI) = 1.41–18.17], management and professional position (OR = 3.89, 95% CI = 1.34–11.29), and having financial problem (OR = 3.29, 95% CI = 1.53–7.06). Work burnout was associated with management and professional position (OR = 7.26, 95% CI = 1.84–28.59), having problem with colleagues (OR = 2.85, 95% CI = 1.08–7.50), and having financial problem (OR = 4.41, 95% CI = 1.82–10.72), while age (OR = 1.12, 95% CI = 1.00–1.25) and male gender (OR = 7.14, 95% CI = 2.00–25.55) were significant factors for client burnout. There were moderate-to-strong correlations between CBI, DASS-21, and WHOQOL-BREF scores (P values &lt;0.01). In mediation analysis, mental ill-health was shown to have significant mediating effect in the relationship between burnout and poor QOL. Such findings need to be replicated across different hospital settings. Studies on effectiveness strategies to manage identified issues will be required.

Feasibility of the Internet Attachment-Based Compassion Therapy in the General Population: Protocol for an Open-Label Uncontrolled Pilot Trial

Background

Compassion-based interventions delivered over the internet are showing promising results for the promotion of psychological health and well-being. Several studies have highlighted their feasibility, acceptance, and preliminary efficacy. However, this is an incipient field of research, and to the best of our knowledge, there are no data available from Spanish-speaking countries.

Objective

The aim of this study is to investigate the feasibility, acceptance, and preliminary efficacy of the Internet Attachment–Based Compassion Therapy (iABCT), a web-based version of the Attachment-Based Compassion Therapy, in Spanish speakers from the general population.

Methods

This feasibility study features a single-arm, uncontrolled, within-group design with an embedded qualitative and quantitative process evaluation at baseline, immediately after the intervention and at the 3-month follow-up. A minimum of 35 participants from the general population will be allocated to iABCT. Feasibility measures will include attrition rate, patterns of use of the web-based system, and participants’ acceptability, usability, and opinion. The primary outcome was measured using the Pemberton Happiness Index. Secondary outcomes were measured using the Compassion Scale, Self-Compassion Scale, Forms of Self-Criticizing/Attacking and Self-Reassuring Scale-Short form, Five Facets of Mindfulness Questionnaire, Relationships Questionnaire, General Health Questionnaire, Non-Attachment Scale, International Positive and Negative Affect Schedule Short Form, Purpose-In-Life Test, and difficulties regarding the practice of compassion (Compassion Practice Quality Questionnaire). Mixed models will be used to evaluate primary and secondary outcome measures. A qualitative content analysis of the participants’ qualitative responses will also be performed.

Results

Enrollment started in February 2020 and will be finished in April 2020. Data analysis will start in October 2020.

Conclusions

To our knowledge, this study will, for the first time, show data on the feasibility, acceptability, and preliminary efficacy of web-based compassion (and self-compassion) training—that is, the adapted iABCT—in Spanish speakers from the general population. Further aspects of their implementation (ie, facilitators, barriers, and unwanted effects) and mechanisms of change will be investigated. This study will allow the revision and fine-tuning of the developed intervention, study design, and planning procedures, as well as the initiation of a future randomized controlled trial.

The Associations of Family Functioning, General Well-Being, and Exercise with Mental Health among End-Stage Renal Disease Patients

OBJECTIVE

This study aims to explore the relationships of family functioning, general well-being, and exercise with psychological distress. Furthermore, we investigated the special roles of general well-being and exercise on the association between family functioning and psychological distress.

METHODS

Of 769 end-stage renal disease (ESRD) patients participated in the cross-sectional study which consisted of the 12-item General Health Questionnaire (GHQ-12), the Family APGAR Scales, and the General Well-Being Schedule. The collected data were analyzed using multiple linear regression analysis and path analysis.

RESULTS

The prevalence of psychological distress was 72.3%. Family functioning, general well-being and exercise were associated factors of psychological distress (p<0.05). The indirect effect of family functioning on psychological distress was partially mediated by general well-being (Effect=-0.08, 95% CI=-0.11, -0.04). In addition, the effect of family functioning on general well-being was moderated by exercise (Index=-0.092, SE=0.033, 95% CI=-0.159, -0.029).

CONCLUSION

The prevalence of psychological distress among ESRD patients was high. Family functioning, general well-being and exercise were associated with psychological distress. Family functioning could affect psychological distress partially by affecting general well-being. Furthermore, exercise had a significant moderating effect on the relationship between family functioning and general well-being.

Universal Mental Health Interventions for Children and Adolescents: A Systematic Review of Health Economic Evaluations

BACKGROUND

Effective mental health interventions may reduce the impact that mental health problems have on young people's well-being. Nevertheless, little is known about the cost effectiveness of such interventions for children and adolescents.

OBJECTIVES

The objectives of this systematic review were to summarize and assess recent health economic evaluations of universal mental health interventions for children and adolescents aged 6-18 years.

METHODS

Four electronic databases were searched for relevant health economic studies, using a pre-developed search algorithm. Full health economic evaluations evaluating the cost effectiveness of universal mental health interventions were included, as well as evaluations of anti-bullying and suicide prevention interventions that used a universal approach. Studies on the prevention of substance abuse and those published before 2013 fell outside the scope of this review. Study results were summarised in evidence tables, and each study was subject to a systematic quality appraisal.

RESULTS

Nine studies were included in the review; in six, the economic evaluation was conducted alongside a clinical trial. All studies except one were carried out in the European Union, and all but one evaluated school-based interventions. All evaluated interventions led to positive incremental costs compared to their comparators and most were associated with small increases in quality-adjusted life-years. Almost half of the studies evaluated the cost effectiveness of cognitive behavioural therapy-based interventions aimed at the prevention of depression or anxiety, with mixed results. Cost-effectiveness estimates for a parenting programme, a school-based social and emotional well-being programme and anti-bullying interventions were promising, though the latter were only evaluated for the Swedish context. Drivers of cost effectiveness were implementation costs; intervention effectiveness, delivery mode and duration; baseline prevalence; and the perspective of the evaluation. The overall study quality was reasonable, though most studies only assessed short-term costs and effects.

CONCLUSION

Few studies were found, which limits the possibility of drawing strong conclusions about cost effectiveness. There is some evidence based on decision-analytic modelling that anti-bullying interventions represent value for money. Generally, there is a lack of studies that take into account long-term costs and effects.

The social return on investment of a new approach to heart failure in the Spanish National Health System

AIMS

We aim to agree on a set of proposals to improve the current management of heart failure (HF) within the Spanish National Health System (SNHS) and apply the social return on investment (SROI) method to measure the social impact that these proposals would generate.

METHODS AND RESULTS

A multidisciplinary working team of 16 experts was set up, with representation from the main stakeholders regarding HF: medical specialists (cardiologists, internal medicine physicians, general practitioners, and geriatric physicians), nursing professionals, health management professionals, patients, and informal caregivers. This team established a set of proposals to improve the management of HF according to the main areas of HF care: emergency and hospitalization, primary care, cardiology, and internal medicine. A forecast-type SROI method, with a 1-year time frame, was applied to measure the social impact resulting from the implementation of these proposals. The required investment and social return were estimated and summarized into a ratio indicating how much social return could be generated for each euro invested. Intangible returns were included and quantified through financial proxies. The approach to improve the management of HF consisted of 28 proposals, including the implementation of a case management nurse network, standardization of operational protocols, psychological support, availability of echocardiography machines at emergency departments, stationary units and primary care, early specialist visits after hospital discharge, and cardiac rehabilitation units, among others. These proposals would benefit not only patients and their informal caregivers but also the SNHS. Regarding patients, proposals would increase their autonomy in everyday activities, decrease anxiety, increase psychological and physical well-being, improve pharmacological adherence and self-care, enhance understanding of the disease, delay disease progression, expedite medical assessment, and prevent the decrease in work productivity associated with HF management. Regarding informal caregivers, proposals would increase their quality of life; improve their social, economic, and emotional well-being; and reduce their care burden. The SNHS would benefit from shorter stays of HF patients at intensive care units and reduction of hospitalizations and admissions to emergency departments. The investment needed to implement these proposals would amount to €548m and yield a social return of €1932m, that is, €3.52 for each euro invested.

CONCLUSIONS

The current management of HF could be improved by a set of proposals that resulted in an overall positive social return, varying between areas of analysis. This may guide the allocation of healthcare resources and improve the quality of life of patients with HF.

An Updated Systematic Review of Studies Mapping (or Cross-Walking) Measures of Health-Related Quality of Life to Generic Preference-Based Measures to Generate Utility Values

BACKGROUND

Mapping is an increasingly common method used to predict instrument-specific preference-based health-state utility values (HSUVs) from data obtained from another health-related quality of life (HRQoL) measure. There have been several methodological developments in this area since a previous review up to 2007.

OBJECTIVE

To provide an updated review of all mapping studies that map from HRQoL measures to target generic preference-based measures (EQ-5D measures, SF-6D, HUI measures, QWB, AQoL measures, 15D/16D/17D, CHU-9D) published from January 2007 to October 2018.

DATA SOURCES

A systematic review of English language articles using a variety of approaches: searching electronic and utilities databases, citation searching, targeted journal and website searches.

STUDY SELECTION

Full papers of studies that mapped from one health measure to a target preference-based measure using formal statistical regression techniques.

DATA EXTRACTION

Undertaken by four authors using predefined data fields including measures, data used, econometric models and assessment of predictive ability.

RESULTS

There were 180 papers with 233 mapping functions in total. Mapping functions were generated to obtain EQ-5D-3L/EQ-5D-5L-EQ-5D-Y (n = 147), SF-6D (n = 45), AQoL-4D/AQoL-8D (n = 12), HUI2/HUI3 (n = 13), 15D (n = 8) CHU-9D (n = 4) and QWB-SA (n = 4) HSUVs. A large number of different regression methods were used with ordinary least squares (OLS) still being the most common approach (used ≥ 75% times within each preference-based measure). The majority of studies assessed the predictive ability of the mapping functions using mean absolute or root mean squared errors (n = 192, 82%), but this was lower when considering errors across different categories of severity (n = 92, 39%) and plots of predictions (n = 120, 52%).

CONCLUSIONS

The last 10 years has seen a substantial increase in the number of mapping studies and some evidence of advancement in methods with consideration of models beyond OLS and greater reporting of predictive ability of mapping functions.

Cross-cultural measurement invariance of the General Health Questionnaire-12 in a German and a Colombian population sample

While the General Health Questionnaire, 12-item version (GHQ-12) has been widely used in cross-cultural comparisons, rigorous tests of the measurement equivalence of different language versions are still lacking. Thus, our study aims at investigating configural, metric and scalar invariance across the German and the Spanish version of the GHQ-12 in two population samples. The GHQ-12 was applied in two large-scale population-based samples in Germany (N = 1,977) and Colombia (N = 1,500). To investigate measurement equivalence, confirmatory factor analyses were conducted in both samples. In the German sample mean GHQ-12 total scores were higher than in the Colombian sample. A one-factor model including response bias on the negatively worded items showed superior fit in the German and the Colombian sample; thus both versions of the GHQ-12 showed configural invariance. Factor loadings and intercepts were not equal across both samples; thus GHQ-12 showed no metric and scalar invariance. As both versions of the GHQ-12 did not show measurement equivalence, it is not recommendable to compare both measures and to conclude that mental distress is higher in the German sample, although we do not know if the differences are attributable to measurement problems or represent a real difference in mental distress. The study underlines the importance of measurement equivalence in cross-cultural comparisons.

Evaluation of the quality of life in patients with arsenic keratosis

BACKGROUND

Chronic exposure to inorganic arsenic is an important public health problem and leads to hyperpigmentation, hyperkeratosis, Bowen's disease and non-melanoma skin cancers in humans. Arsenic keratosis is the most common skin change that is associated with arsenic exposure. It may be an indicator of arsenic induced health hazards.

OBJECTIVE

To determine the needs of patients with arsenic keratosis by evaluating the impact of disease on the quality of life with respect to treatment and provide rehabilitation services.

METHODS

A total of 47 subjects with arsenic hyperkeratosis, were enrolled in this crossover study. The demographics, smoking status and the presence of chronic diseases diagnosed by the physician were recorded. Weight and height of the subjects were measured and BMI was calculated. The patients were asked to respond the visual analogue scale and EuroQoL-5D scales for assessing the pain and quality of life impairment associated with arsenic hyperkeratosis.

RESULTS

In the study group, moderate to severe problems were reported in 78.7% of patients for pain/uncomfortable condition domains and in 91.5% in anxiety/depression domains. Lower quality of life was reported in those with associated chronic disorders, at an advanced age, in thin patients and in those with severe lesions.

CONCLUSION

According to our knowledge, our study is the first one measuring the quality of life in patients with arsenic keratosis in the literature. By this study, we tried to underline the guidance of health services to be developed towards the needs of patients and the need for the development of new health policies by determining the requirements of these patients.

Cost-effectiveness analysis of single-session walk-in counselling. J Ment Health 2017;27:560-566. [PMID: 28675324 DOI: 10.1080/09638237.2017.1340619]

BACKGROUND

An increasing number of family service agencies and community-based mental health service providers are implementing a single-session walk-in counselling (SSWIC) as an alternative to traditional counselling. However, few economic evaluations have been undertaken.

AIMS

To conduct a cost-effectiveness analysis of two models of service delivery, SSWIC compared to being waitlisted for traditional counselling.

METHODS

A quasi-experimental design was employed. Data were collected from two community-based Family Service Agencies, one using SSWIC and one using traditional counselling. Participants were assessed at baseline and four weeks after the baseline. Cost-effectiveness was estimated from the societal and payer's perspective.

RESULTS

The societal and payer's costs for SSWIC were higher than for those waiting for traditional counselling, and health outcomes were better. SSWIC is not cost-effective compared to being on the waitlist for traditional counselling (or, for a few patients, having received counselling, but after a wait of several weeks).

CONCLUSIONS

SSWIC has the potential to reduce the pressure on the mental health care system by reducing emergency visits and wait lists for ongoing mental health services and eliminating costly-no shows at counselling appointments. Long-term studies involving multiple walk-in counselling services and comparison services are needed to support the findings of this study.

Assessing outcomes for cost-utility analysis in mental health interventions: mapping mental health specific outcome measure GHQ-12 onto EQ-5D-3L

Background

Many intervention-based studies aiming to improve mental health do not include a multi-attribute utility instrument (MAUI) that produces quality-adjusted life-years (QALYs) and it limits the applicability of the health economic analyses. This study aims to develop ‘crosswalk’ transformation algorithm between a measure for psychological distress General Health Questionnaire (GHQ-12) and MAUI EuroQoL (EQ-5D-3L).

Methods

The study is based on a survey questionnaire sent to a random sample in four counties in Sweden in 2012. The survey included GHQ-12 and EQ-5D instruments, as well as a question about self-rated health. The EQ-5D index was calculated using the UK and the Swedish tariff values. Two OLS models were used to estimate the EQ-5D health state values using the GHQ-12 as exposure, based on the respondents (n = 17, 101) of two counties. The algorithms were applied to the data from two other counties, (n = 15, 447) to check the predictive capacity of the models.

Results

The final models included gender, age, self-rated health and GHQ-12 scores as a quantitative variable. The regression equations explained 40 % (UK tariff) and 46 % (Swedish tariff) of the variances. The model showed a satisfying predictive capacity between the observed and the predicted EQ-5D index score, with Pearson correlation = 0.65 and 0.69 for the UK and Swedish models, respectively.

Conclusion

The algorithms developed in this study can be used to determine cost-effectiveness of services or interventions that use GHQ-12 as a primary outcome where the utility measures are not collected.

Sexual orientation and symptoms of common mental disorder or low wellbeing: combined meta-analysis of 12 UK population health surveys

BACKGROUND

Previous studies have indicated increased risk of mental disorder symptoms, suicide and substance misuse in lesbian, gay and bisexual (LGB) adults, compared to heterosexual adults. Our aims were to determine an estimate of the association between sexual orientation identity and poor mental health and wellbeing among adults from 12 population surveys in the UK, and to consider whether effects differed for specific subgroups of the population.

METHODS

Individual data were pooled from the British Cohort Study 2012, Health Survey for England 2011, 2012 and 2013, Scottish Health Survey 2008 to 2013, Longitudinal Study of Young People in England 2009/10 and Understanding Society 2011/12. Individual participant meta-analysis was used to pool estimates from each study, allowing for between-study variation.

RESULTS

Of 94,818 participants, 1.1 % identified as lesbian/gay, 0.9 % as bisexual, 0.8 % as 'other' and 97.2 % as heterosexual. Adjusting for a range of covariates, adults who identified as lesbian/gay had higher prevalence of common mental disorder when compared to heterosexuals, but the association was different in different age groups: apparent for those under 35 (OR = 1.78, 95 % CI 1.40, 2.26), weaker at age 35-54.9 (OR = 1.42, 95 % CI 1.10, 1.84), but strongest at age 55+ (OR = 2.06, 95 % CI 1.29, 3.31). These effects were stronger for bisexual adults, similar for those identifying as 'other', and similar for 'low wellbeing'.

CONCLUSIONS

In the UK, LGB adults have higher prevalence of poor mental health and low wellbeing when compared to heterosexuals, particularly younger and older LGB adults. Sexual orientation identity should be measured routinely in all health studies and in administrative data in the UK in order to influence national and local policy development and service delivery. These results reiterate the need for local government, NHS providers and public health policy makers to consider how to address inequalities in mental health among these minority groups.

A Cost-Effectiveness Analysis of the Swedish Universal Parenting Program All Children in Focus

OBJECTIVE

There are few health economic evaluations of parenting programs with quality-adjusted life-years (QALYs) as the outcome measure. The objective of this study was, therefore, to conduct a cost-effectiveness analysis of the universal parenting program All Children in Focus (ABC). The goals were to estimate the costs of program implementation, investigate the health effects of the program, and examine its cost-effectiveness.

METHODS

A cost-effectiveness analysis was conducted. Costs included setup costs and operating costs. A parent proxy Visual Analog Scale was used to measure QALYs in children, whereas the General Health Questionnaire-12 was used for parents. A societal perspective was adopted, and the incremental cost-effectiveness ratio was calculated. To account for uncertainty in the estimate, the probability of cost-effectiveness was investigated, and sensitivity analyses were used to account for the uncertainty in cost data.

RESULTS

The cost was € 326.3 per parent, of which € 53.7 represented setup costs under the assumption that group leaders on average run 10 groups, and € 272.6 was the operating costs. For health effects, the QALY gain was 0.0042 per child and 0.0027 per parent. These gains resulted in an incremental cost-effectiveness ratio for the base case of € 47 290 per gained QALY. The sensitivity analyses resulted in ratios from € 41 739 to € 55 072. With the common Swedish threshold value of € 55 000 per QALY, the probability of the ABC program being cost-effective was 50.8 percent.

CONCLUSION

Our analysis of the ABC program demonstrates cost-effectiveness ratios below or just above the QALY threshold in Sweden. However, due to great uncertainty about the data, the health economic rationale for implementation should be further studied considering a longer time perspective, effects on siblings, and validated measuring techniques, before full scale implementation.

Health Utility Values Associated with Surgical Site Infection: A Systematic Review

BACKGROUND

Surgical site infection (SSI) is a costly postoperative complication whose impact on patients' health-related quality of life is highly uncertain and has not been summarized to date.

OBJECTIVE

The objective was to summarize the evidence base on SSI health utility values reported in patient-level studies and decision models.

METHODS

A systematic review of SSI utility values reported in patient-level and decision modeling studies was carried out. Studies in which utility values for SSI were either invoked (e.g., model-based economic evaluations) or elicited (e.g., valuation exercises), or at least one non-preference-based instrument was administered to patients with SSI after open surgery were included. Mapping algorithms were used, where appropriate, to calculate utilities from primary data. Results were summarized narratively, and the quality of the utility values used in the included modeling studies was assessed.

RESULTS

Of 6552 records identified in the database search, 28 studies were included in the review: 19 model-based economic evaluations and 9 patient-level studies. SSI utility decrements ranged from 0.04 to 0.48, of which 19 ranged from 0.1 to 0.3. SSI utility decrements could be calculated for three patient-level studies, and their values ranged from 0.05 (7 days postoperatively) to 0.124 (1 year postoperatively). In most modeling studies, SSI utilities were informed by authors' assumptions or by secondary sources.

CONCLUSIONS

SSI may substantially affect patients' health utility and needs to be considered when modeling decision problems in surgery. The evidence base for SSI utilities is of questionable quality and skewed toward orthopedic surgery. Further research must concentrate on producing reliable estimates for patients without orthopedic problems.

Did past economic prosperity affect the health related quality of life predictors? A longitudinal study on a representative sample of Slovenian family medicine patients

Background

Health related quality of life (HRQOL) as an important measure of medical outcomes has been shown to be associated with demographic factors and the most common mental and chronic somatic diseases. This study’s aim was to identify factors predicting changes in HRQOL over a follow-up period in a representative sample of Slovenian family medicine patients.

Methods

In a longitudinal multi-centred study between 2003 and 2005, data were collected from 1118 consecutive attendees from 60 family medicine practices in Slovenia on quality of life, socio-demographic factors and the presence of mental disorders, with follow-up after 6 and 24 months. Retrospective information on chronic diseases was obtained from patients` health records. In three time-sequential multiple linear regression models, data on 601 patients (53.8%) was analysed to determine factors associated with each component score of quality of life.

Results

At baseline the patients were 48.58 (SE = 0.58) years of age, over half were women (386 (64.2%)) and most were Slovenian (548 (91.2%)). Quality of life was seen to improve over the two-year period. Factors significantly and consistently associated with a better mental component score of quality of life were social support, satisfactory circumstances in patients` household and absence of anxiety. Major life events in the past year and depression were shown to be risk factors for mental and physical components, while level of education, absence of long-term disability and chronic pain were identified as predictors of the physical component.

Conclusions

Detection and successful treatment of depression and anxiety has a potential to lead to improved quality of life in family medicine attendees; family physicians should be alert for the early onset of these conditions, knowing that symptoms of chronic pain, depression and anxiety often overlap in patients. Poorly educated patients and those lacking social support and/or satisfactory household circumstances should be recognised and empowered, and appropriate coping mechanisms should be introduced.

Media-delivered cognitive behavioural therapy and behavioural therapy (self-help) for anxiety disorders in adults

BACKGROUND

Anxiety disorders are the most common mental health problems. They are chronic and unremitting. Effective treatments are available, but access to services is limited. Media-delivered behavioural and cognitive behavioural interventions (self-help) aim to deliver treatment with less input from professionals compared with traditional therapies.

OBJECTIVES

To assess the effects of media-delivered behavioural and cognitive behavioural therapies for anxiety disorders in adults.

SEARCH METHODS

Published and unpublished studies were considered without restriction by language or date. The Cochrane Depression, Anxiety and Neurosis Review Group's Specialized Register (CCDANCTR) was searched all years to 1 January 2013. The CCDANCTR includes relevant randomised controlled trials from the following bibliographic databases: The Cochrane Library (all years), EMBASE (1974 to date), MEDLINE (1950 to date) and PsycINFO (1967 to date). Complementary searches were carried out on Ovid MEDLINE (1950 to 23 February 2013) and PsycINFO (1987 to February, Week 2, 2013), together with International trial registries (the trials portal of the World Health Organization (ICTRP) and ClinicalTrials.gov). Reference lists from previous meta-analyses and reports of randomised controlled trials were checked, and authors were contacted for unpublished data.

SELECTION CRITERIA

Randomised controlled trials of media-delivered behavioural or cognitive behavioural therapy in adults with anxiety disorders (other than post-traumatic stress disorder) compared with no intervention (including attention/relaxation controls) or compared with face-to-face therapy.

DATA COLLECTION AND ANALYSIS

Both review authors independently screened titles and abstracts. Study characteristics and outcomes were extracted in duplicate. Outcomes were combined using random-effects models, and tests for heterogeneity and for small study bias were conducted. We examined subgroup differences by type of disorder, type of intervention provided, type of media, and recruitment methods used.

MAIN RESULTS

One hundred and one studies with 8403 participants were included; 92 studies were included in the quantitative synthesis. These trials compared several types of media-delivered interventions (with varying levels of support) with no treatment and with face-to-face interventions. Inconsistency and risk of bias reduced our confidence in the overall results. For the primary outcome of symptoms of anxiety, moderate-quality evidence showed medium effects compared with no intervention (standardised mean difference (SMD) 0.67, 95% confidence interval (CI) 0.55 to 0.80; 72 studies, 4537 participants), and low-quality evidence of small effects favoured face-to-face therapy (SMD -0.23, 95% CI -0.36 to -0.09; 24 studies, 1360 participants). The intervention was associated with greater response than was seen with no treatment (risk ratio (RR) 2.34, 95% CI 1.81 to 3.03; 21 studies, 1547 participants) and was not significantly inferior to face-to-face therapy in these studies (RR 0.78, 95 % CI 0.56 to 1.09; 10 studies, 575 participants), but the latter comparison included versions of therapies that were not as comprehensive as those provided in routine clinical practice. Evidence suggested benefit for secondary outcome measures (depression, mental-health related disability, quality of life and dropout), but this evidence was of low to moderate quality. Evidence regarding harm was lacking.

AUTHORS' CONCLUSIONS

Self-help may be useful for people who are not able or are not willing to use other services for people with anxiety disorders; for people who can access it, face-to-face cognitive behavioural therapy is probably clinically superior. Economic analyses were beyond the scope of this review.Important heterogeneity was noted across trials. Recent interventions for specific problems that incorporate clinician support may be more effective than transdiagnostic interventions (i.e. interventions for multiple disorders) provided with no guidance, but these issues are confounded in the available trials.Although many small trials have been conducted, the generalisability of their findings is limited. Most interventions tested are not available to consumers. Self-help has been recommended as the first step in the treatment of some anxiety disorders, but the short-term and long-term effectiveness of media-delivered interventions has not been established. Large, pragmatic trials are needed to evaluate and to maximise the benefits of self-help interventions.

Investigating differences in health-related quality of life of Greeks and Albanian immigrants with the generic EQ-5D questionnaire

Background. Low socioeconomic status (SES) has been related by previous studies to low self-perceived HRQoL. Health is a major determinant of the society's welfare, and few studies have determined the relevant elements that contribute to health and quality of life in Greece. Aim. The aim of the study was to evaluate and test for differences in HRQoL of Greek and Albanian immigrant population according to ethnicity and their demographic and SES characteristics. Methods. The study was conducted in a sample of 660 age-matched and gender-matched Greeks and Albanian immigrants. Moderate or severe decrease in HRQoL was assessed with the generic tool EQ-5D. Differences were statistically analyzed by t-test and ANOVA. Also, logistic and linear regression analyses were conducted for the dependent variables of the EQ-5D dimensions and VAS scores, respectively. Results. The Albanian immigrants reported better self-perceived health than their Greek counterparts. Health problems increase moderately with age and lower SES and are slightly higher for women than for men. Urbanity and superior education in both Greeks and Albaniansareassociated with worse HRQoL. Conclusion. There are some structural and compositional differences in the self-perceived quality of life between the two ethnicities, as estimated by EQ-5D. The combined information presents to public health providers the relevant data to assess health policies according to health needs.

Quality of life in patients with depression, panic syndrome, other anxiety syndrome, alcoholism and chronic somatic diseases: a longitudinal study in Slovenian primary care patients

AIM

To analyse the correlates between the quality of life and chronic diseases and socio-demographic characteristics of patients in family medicine with a special emphasis on depression, panic syndrome, other anxiety syndrome and alcoholism.

METHODS

In a longitudinal study, the data set of 516 family practice attendees recruited from 60 family practices was analysed. Depression, panic syndrome, other anxiety syndrome and alcoholism were diagnosed using appropriate diagnostic interviews. Quality of life was assessed using the SF-12 questionnaire, measuring a mental health score and a physical health score. Data about the number of chronic somatic diseases were obtained from the patients' medical records.

RESULTS

Physical health score was negatively associated with higher age (β = -0.25, p < 0.001), depression (β = -0.20, p < 0.001) and number of chronic somatic diseases (β = -0.10, p < 0.016) and positively associated with higher education level (β = 0.21, p < 0.001), single marital status (β = 0.09, p < 0.022) and better financial status (β = 0.14, p < 0.001). Linear regression explained 31.8 % of the variance (R(2) = 0.318; p < 0.001). Similarly, mental health score was negatively associated with depression (β = -0.45, p < 0.001) and panic syndrome (β = -0.07, p < 0.001) and positively associated with male gender (β = 0.10, p < 0.015) and better financial status (β = 0.13, p < 0.001). Linear regression explained 45.5 % of the variance (R (2) = 0.455; p < 0.001).

CONCLUSIONS

In family medicine, special attention should be directed to major depression, panic syndrome and number of chronic somatic diseases as they are associated with poorer quality of life.

Evaluation of content on EQ-5D as compared to disease-specific utility measures

PURPOSE

The goal of this study was to appraise the extent of unique content on disease-specific preference-based measures (DSPMs) when contrasted with the EQ-5D using published studies and to inform whether EQ-5D could be inadequate as a utility measure in its content coverage for a given disease-specific application.

METHODS

A structured search of published literature was performed using PubMed and EMBASE/Medline database from Jan 1, 1990 to Mar 31, 2011. Articles were eligible for inclusion if algorithms were developed to convert components from disease-specific measures into utility scores.

RESULTS

Of 1,029 articles identified, 50 studies satisfied the inclusion criteria. The most frequent conditions where DSPMs were developed included cancer (12 studies), coronary artery disease (4 studies), osteoarthritis, rheumatoid arthritis (3 studies of each), obesity, and stroke (2 studies of each). Most studies involved mapping items or scores from disease-specific non-preference-based measures onto a preference-based measure of health such as the EQ-5D. A substantial number of DSPMs appeared to include unique content not covered by EQ-5D dimensions.

CONCLUSIONS

Several conditions were identified as potential areas where the richness of the EQ-5D descriptive system could be enhanced. It is yet unclear whether added dimension(s) would contribute unique explained variance to a utility score. Given the resources required to rigorously develop a utility measure, the need for such measures should be carefully vetted.
