Development and preliminary testing of the new five-level version of EQ-5D (EQ-5D-5L)

PurposeThis article introduces the new 5-level EQ-5D (EQ-5D-5L) health status measure.MethodsEQ-5D currently measures health using three levels of severity in five dimensions. A EuroQol Group task force was established to find ways of improving the instrument’s sensitivity and reducing ceiling effects by increasing the number of severity levels. The study was performed in the United Kingdom and Spain. Severity labels for 5 levels in each dimension were identified using response scaling. Focus groups were used to investigate the face and content validity of the new versions, including hypothetical health states generated from those versions.ResultsSelecting labels at approximately the 25th, 50th, and 75th centiles produced two alternative 5-level versions. Focus group work showed a slight preference for the wording ‘slight-moderate-severe’ problems, with anchors of ‘no problems’ and ‘unable to do’ in the EQ-5D functional dimensions. Similar wording was used in the Pain/Discomfort and Anxiety/Depression dimensions. Hypothetical health states were well understood though participants stressed the need for the internal coherence of health states.ConclusionsA 5-level version of the EQ-5D has been developed by the EuroQol Group. Further testing is required to determine whether the new version improves sensitivity and reduces ceiling effects.

Generation of a Danish TTO value set for EQ-5D health states:

Aims: Health policy decisions should be based on national social preferences. In the absence of a set of Danish health preferences, patient outcome studies using the EQ-5D instrument have typically used UK health state valuations. This article describes the development of a Danish EQ-5D value set. Methods: Regression modelling was based on Time Trade-Off (TTO) data derived from computer-assisted interviews conducted with 1,332 respondents from the Danish general population. Using a split-sample technique, 46 health states were directly valued by the respondents. Five different model types were tested and compared on statistical and theoretical grounds. Eleven different specifications were then tested for the chosen model type to identify the most appropriate model that had high explanatory power and parameters that were both consistent (positively signed) and statistically significant. Results: An additive random effects model was found to be superior to ordinary least squares, fixed effects, random coefficient and censored Tobit modelling approaches. From the 11 model specifications tested, the TTO3 model (main effects model, without an N3 factor) performed best and was used to generate a Danish set of health state preferences. Conclusions: An additive random effects model appears to adequately generate a Danish set of EQ-5D health state preferences. The model has high explanatory power and produces consistent and significant parameters for EQ-5D dimensions and levels. It is recommended that this value set be used in Danish cost-utility studies using EQ-5D.

Danish EQ-5D population norms

Background: The EQ-5D is a widely used generic health-related quality of life instrument that has been used to describe population health and health outcomes in clinical trials and health economic evaluations. Aims: To generate Danish population norms for the EQ-5D index score, stratified by age and gender. Methods: The EQ-5D data from three population health surveys were pooled, thus providing EQ-5D profile data for 15,700 individuals aged 20-79 years. The Danish TTO scoring algorithm was used to weight each respondents profile data to derive a single index score. Mean values were computed by gender and 10-year age groups, and educational groups. Results: In a random sample from the general Danish population, the mean EQ-5D index score ranged between 0.93 for 20—29 year-olds and 0.83 for 70—79 year-olds. Men had a significantly higher score than women in all age groups. Longer education was associated with higher EQ-5D index score in most age groups. Conclusions: The calculated mean values for the EQ-5D index score may be used as reference values for comparative purposes in future Danish population health and evaluative studies.

Chronic diseases in elderly men: underreporting and underdiagnosis

OBJECTIVE prevalence estimates for chronic diseases and associated risk factors are needed for priority setting and disease prevention strategies. The aim of this cross-sectional study was to estimate the self-reported and clinical prevalence of common chronic disorders in elderly men. STUDY DESIGN AND SETTING a questionnaire was sent to a random sample of 4,975 men aged 60-74 years. An age-stratified randomised sample (n = 1,845) of those with complete questionnaires was invited to participate in a telephone interview (n = 864), followed by physical examination (n = 600). Self-reported data on risk factors and disease prevalence were compared with data from hospital medical records. RESULTS physical inactivity, smoking and excessive alcohol intake were reported by 27, 22 and 17% of the study population, respectively. Except for diabetes, all the chronic diseases investigated, including hypertension, musculoskeletal and respiratory diseases were underreported by study participants. Erectile dysfunction and hypogonadism were substantially underreported in the study population even though these diseases were found to affect 48 and 21% of the participants, respectively. CONCLUSIONS the study showed a high prevalence of detrimental life style factors including smoking, excessive alcohol consumption and physical inactivity in elderly Danish men. Except for diabetes and respiratory disease, chronic diseases were underreported and in particular erectile dysfunction and osteoporosis were underdiagnosed in the study population, underlining the importance of awareness of chronic diseases among both the general population and physicians.

Evaluation of a Danish Teaching Program in Breast Self-examination

This study investigated the effect of a BSE training program on womens knowledge, attitudes, and behavior regarding BSE. Postal questionnaires were sent to 629 women who had participated in 1998–2000 in the BSE training program run by Ribe County, Denmark, and to a local matched control group of the same size selected through personal registration numbers. Response rates were 77% and 56%, respectively. A significantly greater number of women who had attended BSE training reported that they knew how and when to do BSE, and what they should do if they discovered breast changes (97% compared to 66% in control group). Similar proportions in each group felt confident of finding any breast changes (57%) and believed that routine BSE can influence the chances of recovery from breast cancer (90%). There were also no significant differences between the intervention and control groups in the reporting of anxiety as a result of performing BSE (24% and 17%, respectively). The intervention group was significantly more likely to perform BSE regularly (66% compared to 52% in control group) and to use a more correct technique (44% compared to 20% in control group). It was concluded that a formal training program increases the likelihood of regular BSE performance with a correct technique.

The relationship between health-related quality of life, obesity and testosterone levels in older men

BACKGROUND quality of life evaluated by Short-Form 36 (SF-36) is decreased in obesity and hypogonadism, but the importance of regional fat mass is unknown. In the present study, we evaluated associations between SF-36, regional fat deposits and bioavailable testosterone (BioT) in ageing men. METHODS a population-based cross-sectional study in older men. Data included SF-36 questionnaires with the dimensions such as physical function, role limitations physical, bodily pain, general health, vitality, social function, role limitations emotional and mental health. Furthermore, waist, lean body mass (measured by dual X-ray absorptiometry), visceral adipose tissue and subcutaneous adipose tissue (SAT) (measured by magnetic resonance imaging) and BioT were established. RESULTS five hundred and ninety-eight men aged 60-74 years were included. The SF-36 dimensions such as physical function, general health, vitality and role limitations functional were inversely associated with waist and SAT and positively associated with BioT. In multiple regression analysis, waist was the body composition measure with the strongest association with SF-36 dimension scores. CONCLUSION SF-36 dimension scores were more closely associated with central obesity than with BioT. CLINICAL TRIAL REGISTRATION NUMBER www.clinicaltrials.gov, NCT00155961.

The descriptive system of the EuroQol Instrument

The EuroQol descriptive system has developed within the context of a generic, index measure of HRQoL. Dimensions have been chosen based on a conceptual process rather than by statistical means such as factor analysis, and have been identified through a review of other generic health status measures. Emphasis has been placed on identifying a common core set of dimensions rather than attempting comprehensive coverage of all those possible, allowing the instrument to be used alongside both other generic measures as well as disease-specific instruments. Another strategic consideration was the requirement to generate a feasible number of health states for later valuation.

Physical violence and health-related quality of life: Danish cross-sectional analyses.

BackgroundThe aim of this study was to evaluate the association between experienced physical violence and health-related quality of life (HRQoL) by comparing self-reported health status for individuals with and without experience of physical violence. Our hypothesis was that individuals exposed to violence would experience worse HRQoL than non-exposed individuals. We tested whether men and women and different age groups experience similar reductions in HRQoL, and the extent to which such differences might be associated with social circumstances and lifestyle conditions. Finally, we explored the HRQoL consequences of exposure to violence in a longer time perspective.MethodsWe used data from self-completed questionnaires in two Danish nationally representative, cross-sectional health interview surveys. Exposure to violence was indicated through specific survey questions (Straus’ conflict tactics scale) enquiring about different types of violence during the last 12 months. Health status of respondents was elicited by the EQ-5D and SF-36 questionnaires. The health status profiles were converted to health score indexes using the Danish algorithm for EQ-5D and the revised Brazier algorithm for SF-6D. Differences in score indexes between the exposed and non-exposed individuals were explored separately for men and women using ordinary least square regression with four age categories as explanatory variables.ResultsIn the 2000 and 2005 surveys, respectively, 4.9% and 5.7% of respondents indicated that they had been exposed to physical violence within the last 12 months. Exposure to violence was more prevalent in the younger age groups and more prevalent for men than women. Respondents exposed to violence had lower score indexes on both the EQ-5D and the SF-6D compared with the non-exposed. Respondents who reported exposure to violence in both 2000 and 2005 reported lower HRQoL than individuals who only reported exposure in one of the surveys.ConclusionsThe results of this study provide evidence for an association between exposure to physical violence and reduction in health-related quality of life.

Effectiveness of a tinnitus management programme: a 2-year follow-up study

BackgroundTinnitus impairs the possibility of leading a normal life in 0.5–1% of the population. While neither medical nor surgical treatment appears effective, counselling may offer some relief. An intervention combining counselling and hearing devices is offered to clients referred to the Centre for Help Aids and Communication (CHC) in southern Denmark. The aims of this exploratory study were to examine i) the characteristics of CHCs clients and their tinnitus, ii) the effectiveness of the treatment, and iii) whether particular client groups benefit more than others.MethodsOne hundred new clients presenting with tinnitus completed the Tinnitus Handicap Inventory (THI) three times – before their first consultation, after one month and after 1–2 years. The scores were tested for significant differences over time using tests for paired data. Logistic regression was used to examine factors associated with a clinically important difference (i.e. THI score improvement of at least 20 points).ResultsAt final follow-up, total THI score was significantly lower than baseline, i.e. 29.8 (CI 25.5–34.2) vs. 37.2 (CI 33.1–37.2), p < 0.01. The programme achieved a clinically important difference for 27% and 24% of the clients one month and 1–2 years after the first consultation, respectively. It appeared that greater improvement in THI score was related to higher baseline THI score and possibly also to treatment by a particular CHC therapist. The absolute reduction in mean THI score after 1–2 years for clients with moderate and severe handicap was 14 and 20 points, respectively, i.e. similar to that previously reported for TRT (14–28 points). The cost of the current programme was approximately 200 EUR per client.ConclusionThe tinnitus management programme appeared to provide significant benefit to many clients at a relatively low cost. It would be useful to conduct a randomised controlled study comparing the current programme with alternative forms of combination counselling/sound therapy approaches.

Do Exercisers With Musculoskeletal Injuries Report Symptoms of Depression and Stress

CONTEXT Sports injuries in athletes can lead to negative emotional responses in terms of anger, anxiety, confusion, and sadness. Severe injuries can be understood as a stressful life event with increased levels of psychological distress, but injury assessment and rehabilitation typically focus on somatic symptoms. OBJECTIVE The primary aim of this study was to estimate the prevalence of depression and emotional stress and to measure self-rated health in regular exercisers presenting to a sports medicine clinic with musculoskeletal injury. The secondary aim was to identify psychosocial factors associated with depression in injured exercisers and the potential need for psychological counseling. DESIGN A cross-sectional survey study. SETTING A sports medicine clinic for injuries of the foot, knee, or shoulder. PARTICIPANTS Regular exercisers with present injuries (N = 694) and exercisers without injuries (N = 494). Regular exercisers were defined as those undertaking moderate exercise at least once a week. INTERVENTION A questionnaire survey completed on paper by patients in a sports medicine clinic and a web-based version completed by online sports communities. MAIN OUTCOME MEASURES Participants completed the Major Depression Inventory, Perceived Stress Scale, health-related quality of life, and questions on sociodemographics, exercise habits, and injury history. RESULTS Symptoms of depression were reported by 12% of injured exercisers and 5% of noninjured controls (P < .001). Clinical stress was found in 30% of injured exercisers and 22% of controls (P = .002), and the EQ-5D-5L Visual Analog Scale score was lower for injured (69 [SD = 19]) than noninjured exercisers (87 [SD = 13], P < .001). Injured exercisers with symptoms of depression reported high stress levels and impaired daily functioning, were younger, and were more likely to have over 10 days injury-related work absence. CONCLUSIONS The authors recommend psychological assessment of exercisers attending a sports medicine clinic for musculoskeletal injury and a supplemental clinical psychological interview for suspected depression or stress-related psychopathology.
