Implications for post critical illness trial design: sub-phenotyping trajectories of functional recovery among sepsis survivors. CRITICAL CARE : THE OFFICIAL JOURNAL OF THE CRITICAL CARE FORUM 2020; 24:577. [PMID: 32977833 PMCID: PMC7517819 DOI: 10.1186/s13054-020-03275-w] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Accepted: 09/04/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND Patients who survive critical illness suffer from a significant physical disability. The impact of rehabilitation strategies on health-related quality of life is inconsistent, with population heterogeneity cited as one potential confounder. This secondary analysis aimed to (1) examine trajectories of functional recovery in critically ill patients to delineate sub-phenotypes and (2) to assess differences between these cohorts in both clinical characteristics and clinimetric properties of physical function assessment tools. METHODS Two hundred ninety-one adult sepsis survivors were followed-up for 24 months by telephone interviews. Physical function was assessed using the Physical Component Score (PCS) of the Short Form-36 Questionnaire (SF-36) and Activities of Daily Living and the Extra Short Musculoskeletal Function Assessment (XSFMA-F/B). Longitudinal trajectories were clustered by factor analysis. Logistical regression analyses were applied to patient characteristics potentially determining cluster allocation. Responsiveness, floor and ceiling effects and concurrent validity were assessed within clusters. RESULTS One hundred fifty-nine patients completed 24 months of follow-up, presenting overall low PCS scores. Two distinct sub-cohorts were identified, exhibiting complete recovery or persistent impairment. A third sub-cohort could not be classified into either trajectory. Age, education level and number of co-morbidities were independent determinants of poor recovery (AUROC 0.743 ((95%CI 0.659-0.826), p < 0.001). Those with complete recovery trajectories demonstrated high levels of ceiling effects in physical function (PF) (15%), role physical (RP) (45%) and body pain (BP) (57%) domains of the SF-36. Those with persistent impairment demonstrated high levels of floor effects in the same domains: PF (21%), RP (71%) and BP (12%). The PF domain demonstrated high responsiveness between ICU discharge and at 6 months and was predictive of a persistent impairment trajectory (AUROC 0.859 (95%CI 0.804-0.914), p < 0.001). CONCLUSIONS Within sepsis survivors, two distinct recovery trajectories of physical recovery were demonstrated. Older patients with more co-morbidities and lower educational achievements were more likely to have a persistent physical impairment trajectory. In regard to trajectory prediction, the PF score of the SF-36 was more responsive than the PCS and could be considered for primary outcomes. Future trials should consider adaptive trial designs that can deal with non-responders or sub-cohort specific outcome measures more effectively.

Abstract
PURPOSE To compare the performance of three-level EuroQol five-dimensions (EQ-5D-3L) and five-level EuroQol five-dimensions (EQ-5D-5L) among common cancer patients in urban China. METHODS A hospital-based cross-sectional survey was conducted in three provinces from 2016 to 2018 in urban China. Patients with breast cancer, colorectal cancer, or lung cancer were recruited to complete the EQ-5D-3L and EQ-5D-5L questionnaires. Response distribution, discriminatory power (indicator: Shannon index [H'] and Shannon evenness index [J']), ceiling effect (the proportion of full health state), convergent validity, and health-related quality of life (HRQoL) were compared between the two instruments. RESULTS A total of 1802 cancer patients (breast cancer: 601, colorectal cancer: 601, lung cancer: 600) were included, with the mean age of 55.6 years. The average inconsistency rate was 4.4%. Compared with EQ-5D-3L (average: H' = 1.100, J' = 0.696), an improved discriminatory power was observed in EQ-5D-5L (H' = 1.473, J' = 0.932), especially contributing to anxiety/depression dimensions. The ceiling effect was diminished in EQ-5D-5L (26.5%) in comparison with EQ-5D-3L (34.5%) (p < 0.001), mainly reflected in the pain/discomfort and anxiety/depression dimensions. The overall utility score was 0.790 (95% CI 0.778-0.801) for EQ-5D-3L and 0.803 (0.790-0.816) for EQ-5D-5L (p < 0.001). A similar pattern was also observed in the detailed cancer-specific analysis. CONCLUSIONS With greater discriminatory power, convergent validity and lower ceiling, EQ-5D-5L may be preferable to EQ-5D-3L for the assessment of HRQoL among cancer patients. However, higher utility scores derived form EQ-5D-5L may also lead to lower QALY gains than those of 3L potentially in cost-utility studies and underestimation in the burden of disease.

Health-related quality of life (EQ-5D + C) among people living in artisanal and small-scale gold mining areas in Zimbabwe: a cross-sectional study. Health Qual Life Outcomes 2020; 18:284. [PMID: 32811504 PMCID: PMC7437047 DOI: 10.1186/s12955-020-01530-w] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/15/2019] [Accepted: 08/06/2020] [Indexed: 11/28/2022] Open
Abstract
Background In Zimbabwe, an estimated 500,000 people work in the sector of artisanal and small-scale gold mining (ASGM). Two million Zimbabweans are dependent on this sector. Using mercury is common to extract gold from ore. Long term exposure to mercury can cause various adverse health conditions including chronic mercury intoxication. The influence of these adverse health effects on the health-related quality of life (HRQoL) is still unknown. The aim of this study is to assess the HRQoL of people who identify themselves as miners, and to analyze potential influencing factors, such as age, years of working with mercury and health conditions caused by mercury exposure. Methods This cross-sectional study assessed the HRQoL using the standardized EQ-5D + C (3 L) questionnaire and collected human specimens (blood, urine) of people living and possibly working in ASGM areas in Zimbabwe. Factors such as age, years of working with mercury and adverse health conditions possibly caused by mercury exposure were analyzed with regards to their influence on the HRQoL. Results The 207 participants (82% male, mean age 38 years) reported 40 different health states. Of the study participants 42.5% reported to be in complete good health while 57.5% reported being unwell in different ways. Nine participants (4.3%) were identified with chronic mercury intoxication, whereas 92 participants (33.3%) had mercury levels above the “Alert” threshold in at least one specimen. Having chronic mercury intoxication has a significant negative influence on the HRQoL, when taking into account age, gender and years of working with mercury. Cognitive problems were the most reported in the questionnaire, however, the association between this domain separately and the HRQoL was not verified. Conclusion This study shows that adverse health effects caused by chronic exposure to mercury, have a negative influence on the HRQoL among people living in ASGM areas.

Clinical and Functional Characteristics of Patients with Unclassifiable Interstitial Lung Disease (uILD): Long-Term Follow-Up Data from European IPF Registry (eurIPFreg). J Clin Med 2020; 9:jcm9082499. [PMID: 32756496 PMCID: PMC7464480 DOI: 10.3390/jcm9082499] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Revised: 07/26/2020] [Accepted: 07/31/2020] [Indexed: 12/15/2022] Open
Abstract
(1) Aim of the study: In spite of extensive research, up to 20% of interstitial lung diseases (ILD) patients cannot be safely classified. We analyzed clinical features, progression factors, and outcomes of unclassifiable ILD (uILD). (2) Methods: A total of 140 uILD subjects from the University of Giessen and Marburg Lung Center (UGMLC) were recruited between 11/2009 and 01/2019 into the European Registry for idiopathic pulmonary fibrosis (eurIPFreg) and followed until 01/2020. The diagnosis of uILD was applied only when a conclusive diagnosis could not be reached with certainty. (3) Results: In 46.4% of the patients, the uILD diagnosis was due to conflicting clinical, radiological, and pathological data. By applying the diagnostic criteria of usual interstitial pneumonia (UIP) based on computed tomography (CT), published by the Fleischner Society, 22.2% of the patients displayed a typical UIP pattern. We also showed that forced vital capacity (FVC) at baseline (p = 0.008), annual FVC decline ≥10% (p < 0.0001), smoking (p = 0.033), and a diffusing capacity of the lung for carbon monoxide (DLco) ≤55% of predicted value at baseline (p < 0.0001) were significantly associated with progressive disease. (4) Conclusions: The most important prognostic factors in uILD are baseline level and decline in lung function and smoking. The use of Fleischner diagnostic criteria allows further differentiation and accurate diagnosis.

Health Qual Life Outcomes 2020; 18:253. [PMID: 32727498 PMCID: PMC7390189 DOI: 10.1186/s12955-020-01475-0] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2018] [Accepted: 07/01/2020] [Indexed: 11/17/2022] Open
Abstract
Background The role of artisanal and small-scale gold mining (ASGM) as a source of income is rapidly gaining importance in the economically difficult times in Zimbabwe. Besides limited epidemiological data, no data about the self-reported health-related quality of life (HRQoL) of artisanal and small-scale gold miners exist. The aim of the project was to access HRQoL of ASGM workers to improve the data base and compare the data to the urban Zimbabwean population. Methods Data from 83 artisanal and small-scale gold miners in Kadoma, Zimbabwe was analysed. The HRQoL was assessed using the EuroQol dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) accompanied by the cognition add-on questionnaire (EQ-5D-3L+C) and associated visual analogue scale (VAS). We described the EQ-5D dimensions and VAS values and computed health utility (HU) values using the Zimbabwean tariff. The proportions of miners reporting no problem in each EQ-5D dimension were compared with corresponding proportions reporting any problem (moderate or severe), and mean HU and VAS values were analysed across subgroups of the sample. To test differences between subgroups, Fisher’s exact test was used and between urban and mining population, Student’s t-test was used. Results The reported health states of miners were homogenous, with a large amount (42%) reporting ‘full health’. Mean (SD) VAS and HU values were 81.0 (17.5) and 0.896 (0.13), respectively. Subgroup analysis showed that miners with a lower education reported significantly more problems in the dimension of daily activities and miners with mercury contact had more problems in the dimensions of pain/discomfort and cognition. Comparison between mining and urban population showed that in the oldest age group, self-rated VAS values of miners were significantly higher than of their urban counterparts. Conclusions There were no significant differences in the HRQoL of mining and urban populations. However, the reason might be adverse health effects faced by the urban population that do not apply to rural mining areas. A higher education level of miners can improve the HRQoL, which is especially impaired by problems in the cognition dimension.

Abstract
Background Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder. Consequently, patients undergo a multidisciplinary treatment that often requires intensive use of medical resources. This study provides an estimate on the cost of illness depending on the clinical severity while also analysing the patients’ health-related quality of life. Methods Primary data from patients and caregivers was collected through a standardised questionnaire. Direct medical, direct non-medical and indirect costs were calculated using the latest German health economic guidelines. Patients were divided into five groups according to the King’s staging system. Health-related quality of life was assessed using EuroQoL Group EQ-5D-5L™ questionnaire. Influencing factors on both total cost and quality of life were examined. Results The mean annual total cost of illness was 78,256€ per patient while the lifetime cost per patient was estimated at 246,184€. The prevalence based total burden yearly therefore was 519,776,352€ in Germany. Nearly half of the costs were attributable to informal care. With increase of the clinical severity stage, costs rose and quality of life decreased. The score of the revised Amyotrophic Laterals Sclerosis Functional Rating Scale was identified as one major influencing factor on total costs, while subjective impairment in daily activities and classification into a care level as opposed to having no care level influenced patients’ quality of life. Conclusion It is essential to understand the socioeconomic burden of a disease. These data can be used to improve patient care standards and quality of life while also serving as a basis for cost-benefit analyses during the approval process of new treatments.

Abstract
Background Psychiatric disorders have a major individual and societal impact. Until now, the association between health-related quality of life and physical disorders has been far more investigated than the association with psychiatric disorders. Patient-reported outcome measures makes it possible to capture the patient perspective to improve treatments and evaluate treatment outcomes. The aim of this study is to measure health-related quality of life with the EQ-5D-Y-5L among patients in child and adolescent psychiatric inpatient care and to test the instrument’s psychometric properties in terms of feasibility and construct validity. Methods Data were collected at the child and adolescent psychiatric inpatient facility in Region Stockholm. A questionnaire including the EQ-5D-Y-5L instrument, the Strengths and Difficulties Questionnaire with an impact supplement and a self-rated health question, was administered for self-completion using paper and pencil, with an interviewer present. The Chi-square test was used to investigate differences in proportion of reported problems in the EQ-5D-Y-5L dimensions and the Mann-Whitney U test was used for differences in mean EQ VAS scores. Feasibility was assessed by investigating proportion of missing and ambiguous answers and Spearman’s and Pearson’s correlation were used to examine construct validity. Results In total 52 adolescents participated in the study and the majority were girls. The most common diagnosis at admission was depressive episode/recurrent depressive disorder. All participants reported problems on at least one dimension. Most problems were reported in the dimension ‘feeling worried, sad or unhappy’, where 64% reported severe or extreme problems. Mean EQ VAS score was 29.2. Feasibility was supported and construct validity indicated as some of the hypothesised correlations between the EQ-5D-Y-5 L and the Strengths and Difficulties Questionnaire were found, however, for ‘doing usual activities’ and ‘having pain or discomfort’ the correlations were weaker than hypothesised. Conclusions This is the first study where the newly developed EQ-5D-Y-5L instrument has been used in psychiatric inpatient care for youth. Participants reported problems in all severity levels in most of the EQ-5D-Y-5L dimensions; mean EQ VAS score was considerably low. Feasibility of the EQ-5D-Y-5L was supported, however other psychometric properties need to be further tested in a larger sample.

Abstract
BACKGROUND There is growing recognition that communication and language can be compromised in persons with multiple sclerosis (MS). However, patient-reported outcome measures (PROMs) designed to measure communication and language function in MS are currently lacking. OBJECTIVES This study aimed to develop and validate a novel PROM, the Communication and Language Assessment questionnaire for persons with Multiple Sclerosis (CLAMS). METHODS One-hundred and ninety-nine participants were recruited internationally through online channels. Participants completed an online questionnaire consisting of 41-items generated from the: (1) La Trobe Communication Questionnaire (LCQ), (2) Speech pathology-specific questionnaire for persons with Multiple Sclerosis (SMS), and (3) published research describing communication and language in MS. These items were then submitted to preliminary psychometric evaluation, including principal component analysis, internal consistency, test-retest reliability, criterion validity, and analyses of floor and ceiling effects. Criterion validity was assessed by comparing the CLAMS with the Communication Participation Item Bank (CPIB). RESULTS The final CLAMS contained 11-items. Internal consistency was high (α = 0.944) and test-retest reliability. All items produced an intra-class correlation coefficient ≥ 0.70. No floor or ceiling effects were present. A statistically significant strong correlation between the CLAMS and the CPIB was identified (r = -0.750, p = ≤ 0.001). CONCLUSION The CLAMS is a reliable and valid PROM that assesses self-perceived communication and language function in MS. This tool can be used for research and clinical purposes to measure intervention outcomes, monitor symptom evolution, evaluate service delivery, facilitate patient-centred care, and as an adjunct to clinical assessment.

Abstract
BACKGROUND Major impairment of health-related quality of life (HRQoL) is one of the main reasons why obese patients request surgical treatment. OBJECTIVE To prospectively analyze the impact of HRQoL between obese patients who underwent surgery and those who were wait-listed. METHODS Between April 2017 and March 2018, 70 surgical and 69 wait-listed patients were interviewed twice, at baseline and at the 12-month follow-up. Quality of life was measured by the SF-12v2 and the Impact of Weight on Quality of Life-Lite (IWQoL-Lite) questionnaires. Sociodemographic-, clinical-, and surgical-related variables were collected. RESULTS One hundred thirty-nine patients were analyzed, showing similar baseline characteristics but differences in HRQoL. Performing more qualified work improved scores on some aspects of the SF-12 survey. In contrast, women scored worse on the self-esteem domain, and men scored worse on the mental health domain. By group, at the 12-month follow-up, statistically significant differences were found among all aspects of the questionnaires between both groups (P < 0.001) and between baseline and postoperative 12-month follow-up in the surgical group (P < 0.001). Furthermore, scores were lower in all domains in the evolution of wait-listed patients, with statistically significant differences among the Bodily Pain, Emotional Role, Mental Health, and Mental Component Summary Domains (P < 0.05). CONCLUSION HRQoL is a multimodal concept that allows the identification of factors impacting obese patients' quality of life. It promotes the benefit of surgery against waiting list delays, which can take up to 4 years in our hospital. Therefore, HRQoL is an important pillar to justify more resources for reducing unacceptable surgical delays.

Abstract
Purpose The association of chronic lymphocytic leukemia (CLL) with health-related quality of life (HRQoL) is rarely studied globally. This study evaluated the psychometric properties of the EORTC-Chronic Lymphocytic Leukaemia (CLL17 [phase III]) module, a newly developed assessment on CLL patients’ HRQoL, among Chinese CLL patients. Methods The Chinese CLL17, comprised of three subscales (symptom burden [SB], physical condition [PC] and worries/fears [WF]), was provided by the developer team through EORTC. A cross-sectional online survey was conducted to collect data. The classical traditional theory (CTT) and the item response theory (IRT) were used to evaluate the psychometric properties of CLL17. Internal consistency reliability was determined by the Cronbach’s alpha and item-total correlation. Dimensionality was verified through confirmatory factor analysis (CFA). Convergent validity was also assessed. The generalized partial credit model was used for the IRT. The difficulty, discrimination, item fit, and differential item functioning (DIF) were calculated to assess the instrument’s psychometric properties. Results In all, 318 patients, aged between 26 and 82 years, completed the questionnaire. A good level of internal reliability was achieved (Cronbach’s alpha = 0.92). The item-total correlation coefficient ranged from 0.46 to 0.72. There was a mid-to-high correlation between CLL17 and domains of EQ-5D and QLQ-C30. The IRT model showed a satisfactory homogeneity, item fit and good discrimination of items, except for item 4, 6 and 16 (< 1.0). low information provided by item 16 and 17. SB and PC provided more information with theta > 0, whereas WF provided more information with theta < 0. Item 17 perform inconsistently for respondents from different age groups (DIF). Conclusion The EORTC-CLL17 Chinese version shows acceptable reliability and validity, making it a valuable instrument to evaluate the impact on the HRQoL of Chinese CLL patients.

Abstract
PURPOSE Consideration of health-related quality of life (HRQoL) and wellbeing outcomes is important to guide healthcare services for youth with obesity, yet youth perspectives may differ from their parents. This study compared youth and parental HRQoL reports and evaluated levels of concordance across HRQoL domains and as a function of youth age, youth gender and parent informant (mother and father). METHODS 376 youths with obesity, recruited from community (N = 223) and hospital settings (N = 153), and their parents (N = 190 mothers; N = 91 fathers), completed the PedsQL. Parental and youth agreement across subgroup dyads (mother; father; child gender; child age) were evaluated using Wilcoxon signed-rank test, intra-correlations coefficients (ICCs) and Bland-Altman plots. RESULTS Compared to norms, HRQoL levels (youth self-report and parental proxy reports) were lower in all domains. Both mother and fathers' HRQoL reports were significantly lower than youths, most notably in physical HRQoL. Youth-parent concordance ranged from poor to moderate (ICC = 0.230-0.618), with lowest agreement for Physical HRQOL. Mothers were better proxies with ICCs being significant in all domains. Youth-father ICCs were significant only for Social (ICC = 0.428) and School (ICC = 0.303) domains. Girl-mother agreement was significant across all domains, while girl-father agreement was significant only in the Social domain (ICC = 0.653). Both mothers and fathers were poor raters for boys, and younger youths (aged ≤ 12), with non-significant ICCs in most HRQoL domains. CONCLUSIONS Parents are poor surrogates for youth HRQoL. Clinicians should be cognizant that parents are not necessarily accurate proxies for youths, and exercise caution when interpreting parent-proxy scores.

Abstract
BACKGROUND The SF-6D is a generic, six-dimensional health-related quality of life (HRQoL) measure derived from a selection of items from the SF-36. OBJECTIVES To translate, culturally adapt and validate the SF-6D for use in Arabic-speaking countries. METHODS The International Quality of Life Assessment (IQOLA) methodology was followed. Two forward translations, one consensus and one backward translation were undertaken. Difficulties encountered were categorized as grammatical, idiomatic, semantic/conceptual, and cultural. The content validity of the final version was tested and Cronbach's alpha test of internal consistency was used for assessing reliability. Confirmatory factor analysis (CFA), was also used to assess construct validity and to test a pre-specified relationship of observed measures. RESULTS Minor changes were made to the forward translation to improve cultural appropriateness. The Backward translation did not reveal major problems and equivalence to the original was confirmed following committee review. A total of 470 participants from Jordan, Egypt, UAE, Qatar and Palestine completed the translated SF-6D. All the incremental indices values are ≥0.90 and close to 1. Item loading values ranged from 0.52 to 0.87. The measurement model weight for those with chronic health conditions ranged from 0.68 to 0.91, and from 0.42 to 0.73 for those without. The percentage of variation in self-reported health state was about 55%. The measurement weight of SF-6D on self-reported health state among chronic responders was 0.87 while among responders reporting no chronic disease was 0.61. The t-value for the difference in measurement weight was -8.93 (p ≤ 0.01). CONCLUSION Arabic translation and cultural adaptation of SF-6D has resulted in an acceptable and culturally-adapted version that can be used in Arabic-speaking countries. Reliability and validity have been confirmed as well as ability to assess the difference in quality of life between patients with chronic health conditions and healthy individuals.

Alegre-de la Rosa OM, Villar-Angulo LM. Health-related quality of life in children who use cochlear implants or hearing aids. Heliyon 2020; 6:e03114. [PMID: 31956708 PMCID: PMC6956757 DOI: 10.1016/j.heliyon.2019.e03114] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2019] [Revised: 11/14/2019] [Accepted: 12/19/2019] [Indexed: 11/28/2022] Open
Abstract
Objectives First, this study aimed at evaluating the health-related quality of life (HRQoL) and socio-demographic characteristics of children with cochlear implants (CIs) and hearing aids (HAs) from the 2 provinces of the Canary Islands (Spain) on the Kid-KINDLR_children_7–13. The second goal was to analyze parental background factors and the perspectives of their children with CIs and HAs on Kid_Kiddo-KINDLR_Parents_ 7–17. Finally, the third objective was to explore agreement between children's self-reports and their parents' reports concerning HRQoL. Design The data consisted of 89 children with CIs and 63 children with HAs and their 89 parents, respectively. The socio-demographic characteristics of children and parental background factors included demographic and audiological variables. Student's t-test, one-way ANOVA, post hoc analysis and 4 concordance correlation coefficients (CCC) were used to address the 3 aims. Results Children with CIs exhibited a perception of better HRQoL in comparison with children with HAs. Among other differences, children with CIs and HAs and their parents were significantly distinct in Setting (i.e., provinces of Tenerife and Gran Canaria) (t = 2.921, p < 0.010). Moreover, parents were significantly different in some background factors (i.e., age, socioeconomic status, and learning). While Cohen's Kappa values for most dimensions were too small, the ICC and Student's t-test expressed only concordance in the overall HRQoL and Physical well-being. Conclusions Children with CIs and their parents demostrated a perception of better HRQoL than children with HAs and their parents. Overall, children's self-ratings of HRQoL differed from their parents' reports.

Abstract
Purpose Chronic fatigue syndrome (CFS)/myalgic encephalopathy (ME) is relatively common in children and is disabling at an important time in their development. This study aimed to develop a conceptual framework of paediatric CFS/ME using the patient-perspective to ensure that the content of a new outcome measure includes the outcomes most important to young people. Methods We developed a child-centred interactive card ranking exercise that included health-related quality of life (HRQoL) outcomes identified from a previous review of the literature as well as qualitative work. Adolescents and their parents selected and ranked the outcomes most important to them and discussed each outcome in further detail. Adolescents were purposively sampled from a single specialist paediatric CFS/ME service in England. Interviews were audio recorded and transcribed verbatim, and thematic framework analysis was used to develop the final conceptual framework. Results We interviewed 43 participants in which there are 21 adolescents, 12–17 years of age with mild–moderate CFS/ME and their parents (20 mothers and 2 fathers). ‘Symptoms’, ‘tiredness’, ‘payback and crashing’ and ‘activities and hobbies’ were ranked most important to improve by both children and parents. Children ranked ‘school’ higher than parents and parents ranked ‘mood’ higher than children. A youth- specific CFS/ME conceptual framework of HRQoL was produced that included 4 outcome domains and 11 subdomains: sleep, tiredness, problems concentrating, individual symptoms, fluctuation and payback, daily and general activities, participation in school, leisure and social life, mood, anxiety and self-esteem. Conclusions An interactive card ranking exercise worked well for adolescents aged 12–17 to elicit the most important outcomes to them and explore each domain in further detail. We developed a final conceptual framework of HRQoL that forms the basis of a new paediatric patient-reported outcome measure (PROM) in CFS/ME.

Prevalence of self-reported language impairment in multiple sclerosis and the association with health-related quality of life: An international survey study. Mult Scler Relat Disord 2019; 39:101896. [PMID: 31869597 DOI: 10.1016/j.msard.2019.101896] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2019] [Revised: 11/25/2019] [Accepted: 12/14/2019] [Indexed: 11/20/2022]
Abstract
BACKGROUND Language impairment has only recently begun to be considered a clinical manifestation of MS. A decline in language abilities can lead to restricted participation in everyday activities that require communication, including vocational, social, and educational contexts. OBJECTIVES The objectives of this study were to identify the prevalence and nature of self-reported language impairment in MS using a validated MS-specific patient-reported outcome measure and to determine the association with health-related quality of life (HRQoL) and demographic and clinical variables. METHODS In this cross-sectional study, 160 persons with MS completed the language items of the Speech pathology-specific questionnaire for persons with MS (SMS) to assess language and the 12-Item Short Form Survey (SF-12) to assess HRQoL. Participants were recruited internationally through professional MS bodies and support groups and completed all questionnaires online. RESULTS 75% of persons with MS in this sample self-reported a language impairment. Of the total sample, 65.7% reported difficulty with word retrieval, 53.8% reported difficulty with expressive language, 49.4% reported difficulty with confrontational naming, and 40.6% reported difficulty with receptive language in spoken discourse. Statistical analyses revealed that age, sex, educational status, country of residence, disease duration, age at time of diagnosis, MS subtype, and medication management, were not associated with the prevalence of self-reported language impairment. Participants with self-reported language impairment had lower HRQoL than those without language impairment, scoring lower on both the SF-12 mental and physical component summary scores, with medium to large effect sizes (Cohen's d = 0.66 - 0.83). Participants with self-reported language impairment had higher rates of unemployment than those without language impairment (χ2 = 18.2; p < 0.001). CONCLUSION Language can be compromised in persons with MS regardless of clinical and demographic characteristics and is associated with lower HRQoL. These findings indicate that frontline healthcare providers need to be aware of potential language impairment in MS and should make timely referrals to speech pathologists for further evaluation and support. Further research is needed to investigate the underlying neural mechanisms of language impairment in MS. In future, this will help guide the design of evidence-based intervention for these symptoms.

Abstract
Background Progressive Early-Onset Scoliosis (EOS) in children may lead to surgical interventions with growth-friendly implants, which require repeated lengthening procedures in order to allow adequate growth. Quality of life was studied using the validated German version of the EOS-Questionnaire (EOSQ-24-G) in surgically treated EOS children with different lengthening modalities. Methods EOSQ-24-G and the KINDLR questionnaire were given to families with EOS children who had been treated by either vertical expandable prosthetic titanium rib implants and repetitive lengthening surgeries every 6 months or children who had received a magnetically expansion controlled implant, which was externally lengthened every 3 months. Results were compared according to differences between the two tests, and with possible influencing factors such as surgical method, severity of scoliosis, relative improvement of curvature, etiology, weight, age, travelling distance, complications, ambulatory ability and others. Results 56 children with an average curve angle of 69° corrected to 33° (52%; average age 5.6 yrs) answered the EOSQ-24-G and the KINDLR after an average follow-up of 3.9 years. Health-related quality of life (HRQoL) was not affected by the initial scoliosis correction, the number of surgeries or the implant type. However, there was a negative correlation with non-ambulatory status, complications during treatment and for children with a neuromuscular scoliosis. Conclusion Using the validated EOSQ-24-G, no statistically significant differences were found between the group of children receiving repetitive surgeries and children with external lengthening procedures without surgery. However, results were influenced by the etiology, complication rate or ambulatory ability. Level of Evidence/Clinical relevance Therapeutic Level IV

Abstract
The EuroQol Group's health descriptive systems, the EQ-5D-3L and its successor introduced in 2009, the EQ-5D-5L, are widely used worldwide for valuing health-related quality of life for cost-utility analysis and patient-reported health outcome measures. A new online tool for creating personal and social EQ-5D-5L value sets was recently developed and trialled in New Zealand (NZ). The tool, which includes extensive checks of the quality of participants' data, implements the PAPRIKA method - a novel type of adaptive discrete choice experiment in the present context - and a binary search algorithm to identify any health states worse than dead. After development and testing, the tool was distributed in an online survey in February and March 2018 to a representative sample of NZ adults (N = 5112), whose personal value sets were created. The tool's extensive data quality checks resulted in a 'high-quality' sub-sample of 2468 participants whose personal value sets were, in effect, averaged to create a social value set for NZ. These results overall as well as feedback from participants indicates that the new valuation tool is feasible and acceptable to participants, enabling valuation data to be relatively easily and cheaply collected. The tool could also be used in other countries, tested against other methods for creating EQ-5D-5L value sets, applied in personalised medicine and adapted to create value sets for other health descriptive systems.

Abstract
Many youth with significant medical needs have difficulty attending traditional schools due to academic, physical, and psychosocial challenges. To meet the needs of these youth and prepare them for a successful transition to a traditional school, a multidisciplinary school program (MSP) provides support in these three domains. The aims of this program evaluation are to describe the operation of the novel MSP, characterize participants, and determine the impact of participation as related to school attendance and health-related quality of life (HRQoL). Attendance in the MSP was significantly higher than school attendance estimates provided by caregivers prior to participation in the program. Youth reported significant improvement in physical functioning and total HRQoL. Caregivers reported significant improvement in academic functioning and total HRQoL of youth. The MSP represents a unique educational model for youth with significant medical issues that also provides physical and psychosocial support. Initial findings highlight the potential positive impact of this model for this population of youth.

Abstract
Purpose The goal of the present study was to determine factors related to a ceiling effect (CE) on the EQ-5D-5L among Japanese patients with prostate cancer (PC). Methods An existent cross-sectional observational study dataset was used. Patients were ≥ 20 years of age and diagnosed with PC. For CE determinants on the EQ-5D-5L, we excluded possible “full-health” patients flagged by the EQ-VAS (score = 100) and/or FACT-P (score = 156) instruments. We then divided them into binary variables: A CE group (EQ-5D-5L score = 1) and others (< 1). The associations between CE, sociodemographic and medical characteristics, and FACT-P subscale scores were examined using a multivariate LASSO selection followed by a binomial logistic regression analysis performed to calculate odds ratios (ORs) and 95% confidence intervals (CIs). Results A total of 362 patients were analyzed. The LASSO selection variables, including all obtained variables, were as follows: age, palliative treatment, FACT-P physical well-being, and PC subscale score. Statistically significant variables predicting CE were palliative treatment (OR 0.23; 95% CI 0.09–0.60), physical well-being (OR 1.54; 95% CI 1.34–1.76), and PC subscale (OR 1.08; 95% CI 1.03–1.14). Conclusions This study revealed that palliative treatment and two FACT-P physical well-being and PC subscale scores were positively related to CE on the EQ-5D-5L. To our knowledge, this is the first study to examine predictors of CE on the EQ-5D-5L. The present results may be helpful for facilitating the consideration of “bolt-on” studies from the standpoint of PC patients.

Abstract
OBJECTIVE EQ-5D-Y-3L is a generic, youth-specific instrument to measure health-related quality of life (HRQoL). It contains five dimensions with three severity levels each. The aim of this study was to identify response levels to extend the German EQ-5D-Y version to four or five severity levels (4L or 5L) and to conduct a pilot test of both versions. METHODS In phase 1, we reviewed existing youth-specific HRQoL instruments and conducted focus group interviews with healthy children and adolescents to identify potential new labels. In individual sorting and response scaling interviews, participants aged 8 to 15 years rated the severity of the identified labels. Based on the results, a 4L and a 5L version were developed. In phase 2, the feasibility of those versions was tested in cognitive interviews with healthy children and adolescents as well as those with a health condition. RESULTS In phase 1, 12 to 16 labels were identified for each dimension. These were rated by 64 children and adolescents in the sorting and response scaling interviews. The included labels covered different severity levels of health impairments. In phase 2, 88% of the 33 children and adolescents preferred the 5L version as it was easier for them to report on their own health in more detail. CONCLUSION Involving the target group of children and adolescents, a German EQ-5D-Y version with five severity levels was developed (EQ-5D-Y-5L) that can be used in children and adolescents aged 8 to 15 years. However, the psychometric properties of the instrument need further investigation. In addition, value sets need to be to developed before the questionnaire is suitable for all fields of application.

Abstract
OBJECTIVE Nonspecific health complaints associated with indoor air are common in work environments. In some individuals, symptoms become persistent without an adequate explanation. The aim was to study factors that associate with the health-related quality of life (HRQoL) of employees with persistent, nonspecific indoor-air-related symptomatology. METHODS We present baseline results of a randomized controlled trial of interventions targeted on the HRQoL of the employees with indoor-air-associated nonspecific symptoms. The main participant-inclusion criterion was the presence of persistent indoor-air-related multiorgan symptoms with no known pathophysiological or environment-related explanation. As a comparison for participants´ HRQoL (n = 52) we used data from the general-population Health 2011 study (BRIF8901) including information on subjects matched to the participants´ working status and age and subjects with asthma, anxiety or depressive disorder, or other chronic conditions with work disability. RESULTS The participants showed greater and a clinically significant impairment of HRQoL [M = 0.83, SE = 0.013] than individuals from the general population [M = 0.95, SE = 0.001, p < .001, Hedges´ g = 2.33] and those with asthma [M = 0.93, SE = 0.005, p < .001, Hedges´ g = 1.46], anxiety and depressive disorder [M = 0.89, SE = 0.006, p < .001, Hedges´ g = 0.73], or a chronic condition with work disability [M = 0.91, SE = 0.003, p < .001, Hedges´ g = 1.11]. Prevalent symptoms of depression, anxiety, and insomnia and poor recovery from work were associated with a poor HRQoL. CONCLUSIONS Individuals with nonspecific indoor-air-associated symptoms have a poorer HRQoL than individuals in the general population with a globally burdensome disease. Psychological distress associated with a poor HRQoL should be considered in the making of decisions about the treatment of these patients. TRIAL REGISTRATION ClinicalTrials.gov, NCT02069002.

Abstract
Background Strengthening primary care is considered a global strategy to address non-communicable diseases and their comorbidity. However, empirical evidence of the longer-term benefits of capacity building programmes for primary care teams contextualised for low- and middle-income countries is scanty. In Thailand, a series of system-based capacity building programmes for primary care teams have been implemented for a decade. An analysis of the relationship between these systems-based trainings in diverse settings of primary care and quantified patient outcomes was needed. Methods Facility-based and community-based cross-sectional surveys were used to obtain data on exposure of primary care team members to 11 existing training programmes in Thailand, and health profiles and health-related quality of life of their patients measured in EuroQol-5 Dimension (EQ-5D) scale. Using a multilevel modelling, the associations between primary care provider’s training and patient’s EQ-5D score were estimated by a generalized linear mixed model (GLMM). Results While exposure to training programmes varied among primary care teams nationwide, District Health Management Learning (DHML) and Contracting Unit of Primary Care (CUP) Leadership Training Programmes, which put more emphasis on bundling of competencies and contextualising of applying such competencies, were positively associated with better health-related quality of life of their multimorbid patients. Conclusions Our report provides systematic feedback to a decade-long investment on system-based capacity building for primary care teams in Thailand, and can be considered as new evidence on the value of human resource development in primary care systems in low- and middle-income countries. Building multiple competencies helps members of primary care teams collaboratively manage district health systems and address complex health problems in different local contexts. Coupling contextualised training with ongoing programme implementation could be a key entity to the sustainable development of primary care teams in low and middle income countries which can then be a leverage for improving patients outcomes.

Abstract
OBJECTIVE Prognostic value of health-related quality of life (HRQoL) data may be important to inform patients in clinical practice and to guide clinical decision-making. Our study investigated the added prognostic value of HRQoL for overall survival (OS) and progression-free survival (PFS) in a large heterogeneous sample of glioma patients, besides known prognostic factors. METHODS We included individual baseline data from previously published randomised controlled trials (RCTs) in glioma patients in which HRQoL was assessed through the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BN20 questionnaires. Multivariable Cox regression models (stratified for newly diagnosed versus recurrent disease) were constructed, first with clinical variables (age, sex, tumour type, performance status, allocated treatment and extent of resection) only and subsequently with HRQoL variables added, separately for OS and PFS. The added prognostic value of HRQoL was calculated using C-indices. RESULTS Baseline HRQoL and clinical data from 15 RCTs were included, comprising 5217 patients. In the model including both clinical and HRQoL variables, better cognitive and role functioning and less motor dysfunction were independently associated with longer OS, whereas better role and cognitive functioning, less nausea and vomiting and more appetite loss were independently associated with prolonged PFS. However, C-indices indicated only a small prognostic improvement of the models for OS and PFS when adding HRQoL to the clinical prognostic variables (+1.1% for OS and +.7% for PFS). CONCLUSION Our findings demonstrate that several baseline HRQoL variables are independently prognostic for OS and PFS, yet the added value of HRQoL to the known clinical prognostic variables was small.

Abstract
INTRODUCTION Data are lacking on impact of Middle East Respiratory Syndrome (MERS) on health-related quality of life (HRQoL) among survivors. METHODS We conducted a cross-sectional survey of MERS survivors who required hospitalization in Saudi Arabia during 2016-2017, approximately 1 year after diagnosis. The Short-Form General Health Survey 36 (SF-36) was administered by telephone interview to assess 8 quality of life domains for MERS survivors and a sample of survivors of severe acute respiratory infection (SARI) without MERS. We compared mean SF-36 scores of MERS and non-MERS SARI survivors using independent t-test, and compared categorical variables using chi-square test. Adjusted analyses were performed using multiple linear regression. RESULTS Of 355 MERS survivors, 83 were eligible and 78 agreed to participate. MERS survivors were younger than non-MERS SARI survivors (mean ± SD): (44.9 years ±12.9) vs (50.0 years ±13.6), p = 0.031. Intensive care unit (ICU) admissions were similar for MERS and non-MERS SARI survivors (46.2% vs. 57.1%), p = 0.20. After adjusting for potential confounders, there were no significant differences between MERS and non-MERS SARI survivors in physical component or mental component summary scores. MERS ICU survivors scored lower than MERS survivors not admitted to an ICU for physical function (p = 0.05), general health (p = 0.01), vitality (p = 0.03), emotional role (p = 0.03) and physical component summary (p < 0.02). CONCLUSIONS Functional scores were similar for MERS and non-MERS SARI survivors. However, MERS survivors of critical illness reported lower quality of life than survivors of less severe illness. Efforts are needed to address the long-term medical and psychological needs of MERS survivors.

Abstract
BACKGROUND Unintentional and intentional burn injuries vary across age groups, gender, income, and global region. In high-income countries, the trend over the last several years has been a reduction in burn incidence, burn severity, length of hospital stay, and mortality rate. However, there is a lack of data on predictors of the health-related quality of life (HRQoL) of major burn survivors extending beyond a follow-up period of 10 years. PATIENTS AND METHODS This single-center cross-sectional study is considering 42 long-term severe burn survivors with deep partial thickness burns and an affected total body surface area (TBSA) of ≥20%. For study eligibility design a minimum follow-up of 10 years was obligatory. Entitled individuals were asked to fill in the generic Short Form 36 (SF-36) questionnaire. The physical (PCS) and mental (MCS) component scores of the SF-36 were used as the primary outcome variables. Putative predictor variables were drawn from medical records. Burn-specific functionality and scar tissue quality were assessed using the Burn Specific Health Scale-Brief (BSHS-B) questionnaire and the Patient and Observer Scar Assessment Scale (POSAS), respectively. Correlation between putative predictor variables and SF-36 norm scores were evaluated by Pearson- and Point-Biserial correlation as well as multivariate linear regression. The SF-36 norm scores were compared to the general German population. RESULTS Mean follow-up was 14 (±3) years with a minimum and maximum of 10 and 28 years, respectively. Mean age at the time of the incident was 37 (±17) years. The majority of individuals were male (74%). The mean burn size was 39 (±17) % (TBSA) with 76% of the individuals showing a full thickness burn. SF-36 norm scores were not statistically different from the general population. Statistically significant independent predictor variables of the physical summary score were: age at the time of the injury (-0.381), time since injury (-0.466), length of hospital stay (-0.356), limb amputation (-0.318), unemployment (-0.433), work (0.593), hand function (0.601), body image (0.518), affect (0.355), simple abilities (0.602), burns involving the hands (-0.339) and back (-0.343), POSAS patient- (-0.521) and observer scores (-0.483). In multivariate analysis, work (4.315), the POSAS Score (-2.082) and the age at the time of the incident (-0.242) were statistically significant predictors. Statistically significant independent predictor variables of the mental summary score were: duration of mechanical ventilation (-0.459), hand function (0.415), body image (0.502), sexual activity (0.625), social support (0.542), burns involving the back (-0.315) and affect (0.692). In multivariate analysis, affect (13.844) and the length of mechanical ventilation (-0.115) were statistically significant independent predictor variables. CONCLUSION Ten years after the burn incident, the quality of life was on average comparable to the one in the general population. Multiple variables seem to influence the physical and mental long-term outcome. Herein presented data may support in adapting and designing follow-up strategies tailored to a patient's burn-specific circumstances.
