Towards a Central-Eastern European EQ-5D-3L population norm: comparing data from Hungarian, Polish and Slovenian population studies

Health-related quality of life assessed by EQ-5D-5L and its determinants among rural adults: result from the Henan rural cohort study

OBJECTIVES

Evidence on the health-related quality of life (HRQoL) among Chinese rural populations and its influence factors were limited. This study aimed to describe the distribution of HRQoL assessed by EQ-5D-5L and its determinants among a Chinese rural population.

METHODS

A total of 23,510 eligible participants (9542 men and 13,968 women) from the Henan rural cohort study were included. Tobit regression and generalized linear models were performed to investigate the associations between demographic characteristics, lifestyle factors, common chronic diseases, and HRQoL.

RESULTS

Of all respondents, the most frequently reported problem was pain/discomfort dimension (23.05%), followed by mobility (12.72%), anxiety/depression (7.77%), and usual activities (6.45%), while the least reported was the self-care dimension (3.84%). The more problems reported in all dimensions with age increased except anxiety/depression. The mean (standard deviation) utility index and VAS score were 0.954 (0.111) and 78.34 (14.80), respectively. The regression analysis indicated that increasing age, former drinkers, poor sleep quality, and suffering from common chronic diseases were significantly associated with low HRQoL, while high education level, average monthly income, and physical activity were significantly associated with high HRQoL.

CONCLUSION

This study described the distribution of HRQoL and its influence factors among the Chinese rural population, which was helpful for medical institutions and policymakers to allocate medical resources and better understand HRQoL among the Chinese rural population.

The Estimate of Parental Quality of Life Loss Due to Respiratory Syncytial Virus (RSV) Hospitalization

BACKGROUND

Respiratory syncytial virus (RSV) is one of the leading causes of pediatric hospitalizations, mainly in children under 2 years of age. Hospitalization affects the caregivers' quality of life (QoL). We assessed the caregivers' QoL during RSV-confirmed hospitalizations of children under 2 years old, identified the most affected QoL dimensions and calculated utilities focusing on the assessment methods and potential confounders.

METHODS

The caregivers filled out the EQ-5D questionnaire, consisting of a descriptive system (assessing 5 QoL dimensions) and a visual analog scale (EQ VAS). Utility, utility loss and quality-adjusted life years (QALY) loss were calculated, and a concordance between the two systems was assessed.

RESULTS

A disturbance in any of the five assessed dimensions was reported by 42% (55 out of 132) of the caregivers, mostly anxiety/depression (37%) and pain/discomfort (17%). The utilities varied between 0.17 and 1 in the descriptive system and 0.33-1 (median 0.86) in the EQ VAS, with a utility loss of 0.14 (IQR: 0.1-0.2). The calculated QALY loss reached a median of 2.45 × 10-3 (IQR: 1.37 × 10-3-4.56 × 10-3) and was not influenced by the patient's age or the final clinical diagnosis (QALY loss for bronchiolitis: 2.74 × 10-3, pneumonia: 1.84 × 10-3, bronchitis: 1.78 × 10-3, differences statistically insignificant). Only a moderate concordance between the descriptive system and the EQ VAS was seen (Spearman's rank correlation coefficient = 0.437, p < 0.05), with the latter revealing a higher degree of QoL disturbances.

CONCLUSIONS

RSV hospitalization influences parental QoL significantly, and anxiety/depression is the most commonly reported issue. Utility impairment scores depend on the assessment method but not on the patient's age or final diagnosis. Thus, the impact of RSV on caregivers' QoL cannot be underestimated.

EQ-5D-3L Norms for the European Older Population: Country-Specific Norms for 15 European Countires Based on the Survey of Health, Ageing, and Retirement in Europe

OBJECTIVES

This study presents a country-specific 3-level version of EQ-5D population norms for the European older population.

METHODS

Norm data were obtained from the fourth wave of the Survey of Health, Ageing and Retirement in Europe, and determined, for each EQ-5D dimension, the EQ-visual analog scale (EQ-VAS) and EQ-5D index values by 7 age groups and sex for 15 European countries. The EQ-5D index values were calculated using the European VAS value set for all countries.

RESULTS

Data resulting from 50 013 older respondents (mean age 65.9 years, range 50-111 years, 55.6% women) revealed an increasing number of self-reported health problems on EQ-5D dimensions and decreasing EQ-VAS scores with increasing age and for women compared with men. There are notable differences between countries in terms of the age gradient, the proportion of respondents in full health, and sex. Across all age groups, problems with pain & discomfort are the most frequent (36%-73% any problems), whereas problems with self-care are the least frequent (3%-31% any problems). The mean EQ-VAS score is 71.2 and the mean European VAS score is 0.79.

CONCLUSIONS

Given the growing number of older adults and elderly people in Europe, these population norms provide a valuable source of reference data that can be used to compare older adults or patient subgroups to the average of the general elderly population in a similar age or sex group in 15 European countries. The index value results may be further used to assess the burden of disease across older European populations and to identify the unmet needs of targeted older patient populations.

In search of a 'pan-European value set'; application for EQ-5D-3L

OBJECTIVES

Country-specific value sets for the EQ-5D are available which reflect preferences for health states elicited from the general population. This allows the transformation of responses on EQ-5D to health state utility values. Only twelve European countries possess country-specific value sets and no value set reflecting the preferences of Europe exists. We aim to estimate a 'pan-European' value set for the EQ-5D-3L, reflecting the preferences for health states of the European population that could help to evaluate health care from the perspective of the European decision-maker.

METHODS

We systematically assessed and compared the methodologies of available EQ-5D-3L time trade-off (TTO) value sets from twelve European countries: Denmark, France, Germany, Hungary, Italy, Netherlands, Poland, Portugal, Romania, Slovenia, Spain and UK. Using their published coefficients, a dataset with utility values for all 243 health states was simulated. Different modelling techniques and model specifications including interaction terms were tested. Model selection was based on goodness-of-fit criteria. We also explored results with application of population size weights.

RESULTS

Methodological, procedural and analytical characteristics of the included EQ-5D-3L valuation studies were quite comparable. An OLS based model was the preferred model to represent European preferences. Weighting with population size made little difference.

CONCLUSIONS

EQ-5D-3L valuation studies were considered of sufficient comparability to form the basis for a new 'pan-European' value set. The method used allows for an easy update when new national value sets become available.

The effect of preexisting radiographic hip osteoarthritis on the functional recovery after surgical treatment of intertrochanteric fractures in elderly patients

OBJECTIVE

The aim of this study was to evaluate the effect of the grade of preexisting radiographic hip osteoarthritis on the functional outcome of elderly patients with intertrochanteric fractures treated by intramedullary fixation.

METHODS

We retrospectively examined the impact of the grade of preexisting osteoarthritis on the functional outcome of 88 patients older than 60 years with intertrochanteric fractures treated by intramedullary fixation. The patients were divided into 2 groups accord ing to the grade of osteoarthritis: group 1, including 52 patients (32 females and 20 males) with Kellgren-Lawrence grades 1 and 2, and group 2, including 36 patients (24 females and 12 males) with Kellgren-Lawrence grades 3 and 4. Functional outcomes were evaluated using the Harris hip score, visual analog scale, EuroQoL general health questionnaire, and the Barthel index.

RESULTS

The mean age was 74.8 ± 5.5 (range=63-87) years in group 1 and 75.06 ± 5.3 (range=64-87) years in group 2. At the last follow-up, the mean Harris hip score was significantly higher in group 1 (71.3 ± 4.3) than that of group 2 (69.5 ± 3.5) (P=.047). There was no signifi cant difference between the groups in terms of the visual analog scale (P=.102), EuroQoL general health questionnaire (P=.144), and the Barthel index (P=.261) scores. The EuroQoL general health questionnaire and Barthel index scores were worse with increasing age.

CONCLUSION

As the grade of hip osteoarthritis increases, it may adversely affect the specific hip score, but this parameter alone may not be a poor prognostic factor that affects the quality of life and daily activity level.

Patient-centred care in Hungary: Contributions to foster a policy agenda

In Hungary, the National Health Insurance Fund provides health care coverage for nearly all residents, but healthcare spending is below the EU's average (6.4% versus 9.9% of the GDP in 2019, respectively). In 1997, patients' rights were established by laws of the healthcare system. The patients' voice, however, has remained weakly embedded in decision-making processes both on the system and individual patient levels. Policy progress achieved in the past years may foster patient-centeredness in health policy decision-making. However, people-reported data are not yet embedded in the Hungarian health information system and national population or household surveys, thus undermining the monitoring of the performance of the health system regarding patient-centred aspects. From the academic research side, several advances have occurred regarding the availability of validated instruments for the measurement of patient-centred aspects. These recent studies have placed Hungary in a uniquely advanced position compared with other countries in the Central and Eastern European (CEE) region. The use of those instruments in clinical guidelines and practices, to the education curricula of future health workers, is still in an early stage.

Musculoskeletal health and capability wellbeing: Associations between the HAQ-DI, ICECAP-A and ICECAP-O measures in a population survey

BACKGROUND

The capability approach has received increasing attention in wellbeing measurement in the past years, but it has still remained an underexplored area in musculoskeletal (MSK) health.

OBJECTIVE

We aimed to explore the capability wellbeing in relation to MSK health, by measuring the associations between the Health Assessment Questionnaire Disability Index (HAQ-DI) physical functioning and the ICECAP-A and ICECAP-O capability wellbeing measures.

DESIGN

A cross-sectional survey was performed in 2019 on a representative sample of the Hungarian general adult population.

METHOD

Capability wellbeing was measured by the ICECAP-A (age-group 18-64) and ICECAP-O (age group 65+) questionnaires. MSK health was defined by the HAQ-DI, the mobility domain of the EQ-5D-3L/-5L health status measures, self-reported walking problems and MSK diagnosis (neck/back/low back defects, hip/knee arthrosis, osteoporosis).

RESULTS

Altogether 2021 individuals (female: 50.1%) participated in the survey with mean (SD) age of 48.7 (17.9) years and HAQ-DI of 0.138 (0.390). ICECAP-A (N = 1568, 77.6%) and ICECAP-O (N = 453, 22.4%) scores were on average (SD) 0.894 (0.126) and 0.828 (0.150), respectively. Spearman correlations between the HAQ-DI and ICECAP-A/-O index scores were moderate (r = -0.303 and -0.496; p < 0.05). Both the ICECAP-A/-O index scores differed significantly (ANOVA test, p < 0.05) across all MSK subgroups. In the ordinary least square regressions, marginal effects of ICECAP-A/-O scores on HAQ-DI were significant (-0.149 and -0.123) when controlling for socio-demographic characteristics.

CONCLUSIONS

MSK health problems are associated with lower capability wellbeing. ICECAP-A/-O might capture effects of MSK conditions not measured by the HAQ-DI or the EQ-5D-5L. Further studies should test these associations in disease-specific samples.

Comparing Quality of Life of General Population and Orthopedic Patients in Slovenia

OBJECTIVE

To our knowledge this is the first study presenting descriptive EQ-5D health profile and VAS scores for orthopedic patients in Slovenia. Furthermore, EQ-5D-3L population norms for Slovenia are presented. The aims of this study are (1) to provide population norms for EQ-5D-3L in Slovenia according to age and sex and (2) to compare different groups of orthopaedic patients' health state among themselves as well as to the general population.

METHODS

Data on orthopedic patients' preoperative health status assessment were recorded (n = 1118). The health status of 4 groups of orthopedic patients was analyzed and compared using EQ VAS and the EQ-5D descriptive profile. The results were compared with Slovenian population norms, which were calculated using the EQ-5D valuation set database from year 2000 (n = 708).

RESULTS

As expected, a higher proportion of patients than the general population report problems on all dimensions. The opposite is true only for mobility and anxiety/depression dimension for shoulder surgery patients. Hip endoscopy patients have the lowest health-related quality of life (HRQoL) out of all patient groups using EQ VAS and EQ-5D descriptive profiles.

CONCLUSION

The population norms presented will be useful for many researchers trying to compare HRQoL among various patient groups or the general population. Separate use of the descriptive profile of the EQ-5D is informative when assessing HRQoL in orthopedic patients and is in line with VAS values. The results can support further studies on health needs assessment as well as decisions on funds allocation among groups of orthopedic patients.

A comparison of European, Polish, Slovenian and British EQ-5D-3L value sets using a Hungarian sample of 18 chronic diseases

BACKGROUND

In the Central and Eastern European region, the British EQ-5D-3L value set is used commonly in quality of life (QoL) studies. Only Poland and Slovenia have country-specific weights. Our study aimed to investigate the impact of value set choice on the evaluation of 18 chronic conditions in Hungary.

METHODS

Patients' EQ-5D-3L index scores were calculated using the VAS-based Slovenian and European and the time-trade-off-based Polish and British value sets. We performed pairwise comparisons of mean index values by dimensions, diagnoses and age groups. We evaluated disease burden by comparing index values matched by age and gender in each condition with those of the general population of the CEE region in all four value sets.

RESULTS

Altogether, 2421 patients (55% female) were included in our sample with the average age of 55.87 years (SD = 17.75). The average Slovenian, European, Polish and British EQ-5D-3L scores were 0.598 (SD = 0.279), 0.661 (SD = 0.257), 0.770 (SD = 0.261) and 0.644 (SD = 0.279), respectively. We found highly significant differences in most diagnoses, with the greatest difference between the Polish and Slovenian index values in Parkinson's disease (0.265). Systematic pairwise comparison across all conditions and value sets revealed greatest differences between the time-trade-off (TTO) and VAS-based value sets as well as varying sensitivity of the disease burden evaluations of chronic disease conditions to the choice of value sets.

CONCLUSIONS

Our results suggest that the choice of value set largely influences the health state utility results in chronic diseases, and might have a significant impact on health policy decisions.
