Differences between adolescents' and parents' reports of health-related quality of life in cystic fibrosis

Child-Parent Agreement in the Assessment of Health-Related Quality of Life Using the CHU9D and the PedsQLTM

OBJECTIVE

This study examined the inter-rater agreement between child-self and parental proxy health-related quality of life (HRQoL) ratings (overall and domain level) using two different generic child-specific measures, the Child Health Utility 9D (CHU9D) and the Pediatric Quality of Life Inventory (PedsQLTM), in a community-based sample of Australian children. A secondary objective was to investigate the impact of age on child-parent agreement across the dimensions of the two measures.

METHODS

A total of 85 child-parent dyads (children aged 6-12 years) recruited from the community completed the self and proxy versions of the CHU9D and the PedsQLTM, respectively. The inter-rater agreement was estimated using Concordance Correlation Coefficients (CCC) and Gwet's Agreement Coefficient (AC1) for the overall sample and across age-groups.

RESULTS

Agreement was low for overall HRQoL for both the CHU9D (CCC = 0.28) and the PedsQLTM (CCC = 0.39). Across the CHU9D dimensions, agreement was the highest for 'sad' (AC1 = 0.83) and lowest for 'tired' (AC1 = 0.31). The PedsQLTM demonstrated stronger agreement (AC1 = 0.41-0.6) for the physical health dimension but weaker for the psychosocial dimensions (AC1 < 0.4). Except for the 'tired' dimension, agreement was consistent across age-groups with the CHU9D, whilst the PedsQLTM showed poor agreement for most of the psychosocial health items among the older age-groups only (8-10 and 11-12 years).

CONCLUSION

This study highlights that the agreement between child and parent proxy reported HRQoL may be influenced by both the measure used and the age of the child. These findings may have implications for the economic evaluation of healthcare interventions and services in child populations when both child and proxy perspectives are considered in the assessment of child HRQoL.

Interventions for improving adherence to airway clearance treatment and exercise in people with cystic fibrosis

BACKGROUND

Cystic fibrosis (CF) is a life-limiting genetic disorder predominantly affecting the lungs and pancreas. Airway clearance techniques (ACTs) and exercise therapy are key components of physiotherapy, which is considered integral in managing CF; however, low adherence is well-documented. Poor physiotherapy adherence may lead to repeated respiratory infections, reduced exercise tolerance, breathlessness, reduced quality of life, malaise and reduced life expectancy, as well as increased use of pharmacology, healthcare access and hospital admission. Therefore, evidence-based strategies to inform clinical practice and improve adherence to physiotherapy may improve quality of life and reduce treatment burden.

OBJECTIVES

To assess the effects of interventions to enhance adherence to airway clearance treatment and exercise therapy in people with CF and their effects on health outcomes, such as pulmonary exacerbations, exercise capacity and health-related quality of life.

SEARCH METHODS

We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. Date of last search: 1 March 2023. We also searched online trials registries and the reference lists of relevant articles and reviews. Date of last search: 28 March 2023.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) and quasi-RCTs of parallel design assessing any intervention aimed at enhancing adherence to physiotherapy in people with CF versus no intervention, another intervention or usual care.

DATA COLLECTION AND ANALYSIS

Two review authors independently checked search results for eligible studies and independently extracted data. We used standard procedures recommended by Cochrane and assessed the certainty of evidence using the GRADE system.

MAIN RESULTS

Two RCTs (77 participants with CF; age range 2 to 20 years; 44 (57%) males) met the inclusion criteria of this review. One study employed an intervention to improve adherence to exercise and the second an intervention to improve adherence to ACT. Both studies measured outcomes at baseline and at three months, but neither study formally assessed our primary outcome of adherence in terms of our planned outcome measures, and results were dependent on self-reported data. Adherence to ACTs One RCT (43 participants) assessed using specifically-composed music alongside ACTs compared to self-selected or no music (usual care). The ACT process consisted of nebuliser inhalation treatment, ACTs and relaxation or antibiotic nebuliser treatment. We graded all evidence as very low certainty. This study reported adherence to ACTs using the Morisky-Green questionnaire and also participants' perception of treatment time and enjoyment, which may influence adherence (outcome not reported specifically in this review). We are uncertain whether participants who received specifically-composed music may be more likely to adhere at six and 12 weeks compared to those who received usual care, risk ratio (RR) 1.75 (95% confidence interval (CI) 1.07 to 2.86) and RR 1.56 (95% CI 1.01 to 2.40) respectively. There may not be any difference in adherence when comparing specifically-composed music to self-selected music at six weeks, RR 1.21 (95% CI 0.87 to 1.68) or 12 weeks, RR 1.52 (95% CI 0.97 to 2.38); or self-selected music to usual care at six weeks, RR 1.44 (95% CI 0.82 to 2.52) or 12 weeks, RR 1.03 (95% CI 0.57 to 1.86). The music study also reported the number of respiratory infections requiring hospitalisation at 12 weeks, with no difference seen in the risk of hospitalisation between all groups. Adherence to exercise One RCT (24 participants) compared the provision of a manual of aerobic exercises, recommended exercise prescription plus two-weekly follow-up phone calls to reinforce exercise practice over a period of three months to verbal instructions for aerobic exercise according to the CF centre's protocol. We graded all evidence as very low certainty. We are uncertain whether an educational intervention leads to more participants in the intervention group undertaking increased regular physical activity at three months (self-report), RR 3.67 (95% CI 1.24 to 10.85), and there was no reported difference between groups in the number undertaking physical activity three times per week or undertaking at least 40 minutes of physical activity. No effect was seen on secondary outcome measures of spirometry, exercise capacity or any CF quality of life domains. This study did not report on the frequency of respiratory infections (hospitalised or not) or adverse events.

AUTHORS' CONCLUSIONS

We are uncertain whether a music-based motivational intervention may increase adherence to ACTs or affect the risk of hospitalisation for a respiratory infection. We are also uncertain whether an educational intervention increases adherence to exercise or reduces the frequency of respiratory infection-related hospital admission. However, these results are largely based on self-reported data and the impact of strategies to improve adherence to ACT and exercise in children and adolescents with stable CF remains inconclusive. Given that adherence to ACT and exercise therapy are fundamental to the clinical management of people with CF, there is an urgent need for well-designed, large-scale clinical trials in this area, which should conform to the CONSORT statement for standards of reporting and use appropriate, validated outcome measures. Studies should also ensure full disclosure of data for all important clinical outcomes.

Clinical characteristics and outcomes of cystic fibrosis in Palestine: Cross sectional study

OBJECTIVE

To assess the clinical characteristics and outcomes of cystic fibrosis in Palestine by studying the quality of life (QoL) of participants.

METHOD

This cross-sectional study involved the application of Cystic Fibrosis Questionnaire-Revised (CFQ-R) to participants attending the pediatric pulmonology clinic at Caritas Baby Hospital between January and May 2017. Health status was assessed by measuring pulmonary function test (FEV₁ ), body mass index (BMI), age of CF diagnosis, and presence of other affected siblings or deaths in the family.

RESULTS

There were 77 participants from 58 families: 46.8% (36/77) were males, and 53.3% (41/77) were females. The mean age was 10.7 years (range: 0.5-36 years). The participants were divided into three groups by age in years: group I ( < 6), II (6-13), and III (≥ 14). The highest and lowest CFQ scores were for the eating domain in group III (55.6 ± 22.5) and the body domain in group II (14.5 ± 17.7), respectively. Mean illness severity was 69.6% (range: 33%-111%). The mean BMI was 15.9 (range: 9.6-23.1). The mean age at the time of diagnosis was 4.2 years (± 6.3). The study showed that 1.7% of the families (1/58) had four affected siblings, and 21% (12/58) had death cases related to CF, of which 58.3% (7/12) were from the Hebron district. Finally, all parameters for CF participants in West Bank, Palestine were noticeably lower than those reported in other countries.

CONCLUSIONS

This study illustrates the need for new therapies for CF participants in Palestine to improve QoL, health status, and longevity.

Comparative analysis of respiratory symptom scores to detect acute respiratory events in children with cystic fibrosis

BACKGROUND

Patient-reported outcomes (PROs) are important outcome measures in research and clinical practice. This study describes the longitudinal variability the Cystic Fibrosis Questionnaire-Revised (CFQ-R) Respiratory score and the Chronic Respiratory Infection Symptom Score (CRISS), as well as their ability to identify acute respiratory events in children with CF.

METHODS

In this prospective observational study, the parent-proxy (6 -13 years) and self-reported (6-18 years) CFQ-R Respiratory score and CRISS (6-18 years) were measured every 3 months over 2 years. The lung clearance index (LCI) and FEV₁ were also measured. We compared the diagnostic accuracy of the PROs in distinguishing acute respiratory events and clinically stable visits, using the minimal important difference of each PRO as the threshold.

RESULTS

A total of 98 children with CF were included. On average, the symptom scores did not change between clinically stable visits. The positive predictive value (PPV) and negative predictive value (NPV) of a ≥8.5-point worsening in the parent-proxy CFQ-R score to identify acute respiratory events (n=119) (PPV 70.2% and NPV 87.0%) were higher than for the self-reported CFQ-R score (PPV 58.9% and NPV 72.2%). The PPV and NPV of an ≥11-point change in the CRISS for acute respiratory events (n=137) was 56.5% and 79.6%, respectively. The PPV and NPV of all PROs were increased when combined with the LCI and/or FEV₁pp.

CONCLUSION

Symptoms scores differ in their ability to identify acute respiratory events in children with CF; PPV and NPV of all PROs were improved when combined with lung function outcomes.

Quality of life is poorly correlated to lung disease severity in school-aged children with cystic fibrosis

BACKGROUND

There is no data exclusively on the relationship between health-related quality-of-life (HRQOL) and lung disease severity in early school-aged children with cystic fibrosis (CF). Using data from the Australian Respiratory Early Surveillance Team for Cystic Fibrosis (AREST CF) we assessed the relationships between HRQOL, lung function and structure.

METHODS

125 children aged 6.5-10 years enrolled in the AREST CF program were included from CF clinics at Royal Children's Hospital (RCH), Melbourne (n = 66) and Perth Children's Hospital (PCH), Perth (n = 59), Australia. Demographics, HRQOL measured by Cystic Fibrosis Questionnaire-Revised (CFQ-R), spirometry, multiple-breath washout (MBW) and chest CT were collected across two years. Correlation between CFQ-R scores and lung structure/function parameters and agreement between parent-proxy and child-reported HRQOL were evaluated.

RESULTS

No correlation was observed between most CFQ-R domain scores and FEV1 z-scores, excepting weak-positive correlation with parent CFQ-R Physical (rho = 0.21, CI 0.02-0.37), and Weight (rho = 0.21, CI 0.03-0.38) domain and child Body domain (rho = 0.26, CI 0.00-0.48). No correlation between most CFQ-R domain scores and LCI values was noted excepting weak-negative correlation with parent Respiratory (rho = -0.23, CI ^-0.41-^-0.05), Emotional (rho = -0.24, CI ^-0.43-^-0.04), and Physical (-0.21, CI ^-0.39-^-0.02) domains. Furthermore, structural lung disease on CT data demonstrated little to no association with CFQ-R parent and child domain scores. Additionally, no agreement between child self-report and parent-proxy CFQ-R scores was observed across the majority of domains and visits.

CONCLUSION

HRQOL correlated poorly with lung function and structure in early school-aged children with CF, hence clinical trials should consider these outcomes independently when determining study end-points.

Poor Health Related Quality of Life and Unhealthy Lifestyle Habits in Weight-Loss Treatment-Seeking Youth

Obesity is associated with unhealthy lifestyle behaviors and poor Health Related Quality of Life (HRQOL). The cumulative effect of lifestyle behaviors on HRQOL has been demonstrated in chronically ill adolescents, but not in adolescents with obesity. The present study aimed to assess the association between HRQOL and adherence to the Mediterranean Diet (MD) and/or low levels of physical activity (PA) in a large sample of outpatient adolescents with overweight or obesity seeking weight loss treatment. Four-hundred-twenty participants were enrolled from 10 Italian outpatient clinics. The demographics and anthropometric features, KIDMED scores, and exercise levels of the participants were collected, together with parental features. The HRQOL was assessed by the Pediatric Quality of Life Inventory (PedsQL™), Adolescents Version 4.0. PedsQL total score and functioning subscales were lower in adolescents who reported one or two unhealthy habits. Compared with the high/intermediate groups, the risk of low HRQOL was twice as high for each unit increase in BMI SDS, while the percentage was reduced by 12.2% for every unit increase in the KIDMED score and by 32.3% for each hour increase of exercise. The clustering of these two unhealthy behaviors conferred a 120% higher risk of low HRQOL. Similarly, adolescents displaying better diet quality and/or a physically more active lifestyle have better physical and psychological functioning. Further studies are needed to disclose whether these characteristics may be predictive of better adherence to weight loss treatment.

Assessing Shared Decision-Making in Cystic Fibrosis Care Using collaboRATE: A Cross-Sectional Study of 159 Programs

There are numerous opportunities for shared decision-making (SDM) in cystic fibrosis (CF) care, yet little is known about patients’ SDM experiences. This study evaluated SDM across 159 CF care programs (4024 participants) in the United States. Shared decision-making was assessed using the patient-reported collaboRATE measure, which was included in the CF Foundation’s Patient and Family Experience of Care Survey over 18 months. Overall, 69% of respondents reported experiencing SDM. Respondents at pediatric programs were more likely to experience SDM than those at adult programs (72% vs 67%, P < .001). Multivariable logistic regression analyses showed a relationship between SDM and patient age, whereby SDM was less likely to occur with patients aged 18 to 24 years, compared to some younger and older age groups (P = .02-<.001). Shared decision-making was more likely to occur at pediatric programs when patients had better general health (P = .02-<.01), and at pediatric and adult programs when patients had better mental health (P = .02-<.001). Disparities in SDM experiences highlight a need to improve decision-making processes in CF care. Interventions tailored for improving SDM among specific patient populations may be particularly advantageous.

Can the Vocal Expression of Intellectually Disabled Individuals Be Used as a Pain Indicator? Initial Findings Supporting a Possible Novice Assessment Method

Pain is difficult to assess in non-verbal populations such as individuals with intellectual and developmental disability (IDD). Due to scarce research in this area, pain assessment for individuals with IDD is still lacking, leading to maltreatment. To improve medical care for individuals with IDD, immediate, reliable, easy to use pain detection methods should be developed. The goal of this preliminary study was to examine the sensitivity of acoustic features of vocal expressions in identifying pain for adults with IDD, assessing their feasibility as a pain detection indicator for those individuals. Such unique pain related vocal characteristics may be used to develop objective pain detection means. Adults with severe-profound IDD level (N = 9) were recorded in daily activities associated with pain (during diaper changes), or without pain (at rest). Spontaneous vocal expressions were acoustically analyzed to assess several voice characteristics. Analyzing the data revealed that pain related vocal expressions were characterized by significantly higher number of pulses and higher shimmer values relative to no-pain vocal expressions. Pain related productions were also characterized by longer duration, higher jitter and Cepstral Peak Prominence values, lower Harmonic-Noise Ratio, lower difference between the amplitude of the 1st and 2nd harmonic (corrected for vocal tract influence; H1H2c), and higher mean and standard deviation of voice fundamental frequency relative to no-pain related vocal productions, yet these findings were not statistically significant, possibly due to the small and heterogeneous sample. These initial results may prompt further research to explore the possibility to use pain related vocal output as an objective and easily identifiable indicator of pain in this population.

Perception Gap in Health-Related Quality of Life Between Young Adult Survivors of Childhood Cancer and Their Family

Young adult survivors of childhood cancer may have a perception gap with their families. Patients aged 18-39 years after treatment of cancer and their families (28 pairs) completed a survey that contained questions on health-related quality of life using the 36-item short form survey. There was a significant difference in the role-social component score (mean difference -2.23; p = 0.04) with family reporting higher scores than patients. Families may overestimate the social function of cancer survivors, emphasizing the importance of the long-term follow-up by taking into account the risk of a gap (IRB approval No.: R2257-1).

Health-Related Quality of Life in Craniofacial Conditions: Concordance Between Child and Parent Reports

INTRODUCTION

Craniofacial conditions (CFCs) profoundly influence health-related quality of life (HRQoL). In children with CFCs, patient-reported outcome measures have become an integral adjunct to more objective surgical outcome measures. Patient-reported outcome measures are designed to assess HRQoL domains. Few studies have evaluated parent and child agreement about HRQoL in the context of CFCs. The aims of this study were to explore the impact of CFCs on HRQoL domains in children and their parents and to determine whether patient and parent perspectives converge.

METHODS

The Craniofacial Conditions Quality of Life Scale (CFC-QoL) is a newly developed 5-domain survey available in child self-report and parent report and in English- and Spanish-language versions. The 5 domains are the following: social impact, psychological function, physical function, family impact, and appearance impact. Children with CFCs (ages 7-21 years) and parents of children with CFCs were recruited via the craniofacial care team clinic at a major metropolitan children's hospital. All children and parents completed the CFC-QoL Scale in their preferred language of English or Spanish. Scale internal consistencies were calculated for child patients and parents, for English and Spanish versions. Scores on the 5 domains were compared for children and parents across English versus Spanish versions.

RESULTS

For children with CFCs (N = 75), the sex was distributed almost equally. Patients were mostly Hispanic (69.3%), and their ages ranged from 7 to 21 years old (M = 13.2, SD = 3.62). The mean values for patient and parent scores were low, suggesting good HRQoL across all 5 domains. Pearson correlation coefficients were computed to explore the interrelationships between patient and parent report for each of the 5 CFC-QoL subscales. For the total sample, patient and parent scores were significantly and moderately positively correlated for all subscales. When analyzed separately based on sex, ethnicity, and diagnostic group, the correlation patterns were not identical to those found for the total sample. When analyzed separately for diagnostic group, there was less consistency in patterns, with patient-parent dyads showing different levels of agreement based on child's diagnostic grouping.

CONCLUSIONS

Although there is substantial agreement between parents and patients when considered on a group level, there is moderate agreement between patients and parents when considered at the dyadic level, underscoring the importance of measuring and considering both perspectives.

Health-related quality of life in post-infectious bronchiolitis obliterans: agreement between children and their proxy

OBJECTIVE

To assess the level of agreement in health-related quality of life between children with Post-infectious Bronchiolitis Obliterans and their parent (so-called proxy).

METHODS

Participants aged between 8and 17 years who had been previously diagnosed with Post-infectious Bronchiolitis Obliterans were regularly followed up at a pediatric pulmonology outpatient clinic. Parents or legal guardians (caregivers) of these patients were also recruited for the study. A validated and age-appropriate version of the Pediatric Quality of Life Inventory 4.0 was used for the assessment of health-related quality of life. Caregivers completed the corresponding proxy versions of the questionnaire. The correlation between self and proxy reports of health-related quality of life was determined by intra-class correlation coefficient and dependent t-tests.

RESULTS

The majority of participants were males (79.4%), and the average age was 11.8 years. Intra-class correlations between each of the Pediatric Quality of Life Inventory 4.0 domains and the total score were all lower than 0.6, with a range between 0.267 (poor) and 0.530 (fair). When the means of each domain and the total score of the questionnaires were compared, caregivers were observed to have a significantly lower health-related quality of life score than children, with the exception of the social domain in which the difference was not significant. However, the differences in score exceeded the critical threshold difference of four points in all other domains.

CONCLUSION

Proxies of children and adolescents with Post-infectious Bronchiolitis Obliterans appear to consistently perceive their children as having lower health-related quality of life than how the patients perceive themselves.

Parent-Child Agreement on Health-Related Quality of Life in Congenital Glaucoma

Purpose

We assess parent-child agreement regarding child's health-related quality of life (HRQoL) in children operated for congenital glaucoma (CG).

Methods

A total of 121 children aged 8 to 18 years (mean age, 11.8 years) operated for CG (mean duration since surgery, 10.2 years) and their parents (mean age, 36.5 years) completed the child and parent versions of the Kidscreen-27 questionnaire, respectively. Psychometric properties of Kidscreen-27 were assessed using Rasch analysis, and child–parent agreement regarding child's HRQoL was investigated using the Bland-Altman limits of agreement (LoA) method.

Results

Minor modifications in the rating scale and deletion of few misfitting items resulted in a psychometrically robust Kidscreen-23 questionnaire. Average parental HRQoL score was higher than the child's own ratings, with a significant difference between their scores (mean ± standard deviation [SD] difference = 0.53 ± 2.58 logits, P = 0.02; lower LoA [95% CI], −4.52 [−5.31 to −3.72] and upper LoA [95% CI], 5.58 [4.79–6.38]). The range of child–parent agreement was wide and bidirectional, with parents tending to underestimate and overestimate their child's HRQoL. Younger children and girls showed greater discordance in their HRQoL with parental reports than adolescents and boys, respectively.

Conclusions

Discordance between CG child's self-report of HRQoL and parent's report indicate that both groups perceive the broader impact of living with CG very differently.

Translational Relevance

The HRQoL as reported by the child with CG and by his/her parent should be viewed as being complementary, rather than interchangeable. Both assessments should be taken into account in clinical practice and research studies.

Comparing parent and child reports of health-related quality of life and their relationship with leisure participation in children and adolescents with Cerebral Palsy

The aim of this study was to examine the level of agreement between reports of health-related quality of life (HR-QoL) obtained from children and adolescents with cerebral palsy (CP) and their parents. We also examined the relationships between child and parent perception of the different domains of HR-QoL and participation dimensions. Sixty-nine children and adolescents with CP and their parents separately completed parallel forms of the KIDSCREEN questionnaire. The Spanish version of the Children's Assessment of Participation and Enjoyment (CAPE) was completed by the child/adolescent. Concordance between the children's and the parents' HR-QoL scores was analyzed via Pearson and intraclass correlations. Differences in means were tested using paired Student's t-tests. Chi-square tests were using to assess the incidence of personal variables in the agreement and disagreement of children-parents' responses. The relationships between HR-QoL and leisure participation was confirmed with Pearson's correlation coefficients. Correlations between child and parent HR-QoL scores were small in 7 domains, medium in 2 and large in the Social Support & Peers domain. Children reported significantly better HR-QoL than their parents did. Participation was positively associated with specific domains of HR-QoL, but only weakly, and there were discrepancies between parent and child reports of HR-QoL. These findings provide interesting information about the importance of hearing the voices of children and adolescents with CP to promote HR-QoL and leisure participation.

Illness Perceptions of Cystic Fibrosis: A Comparison of Young Adults with CF and Same-Aged Peers

In the last two decades, the life expectancy for individuals with Cystic Fibrosis (CF) has increased significantly. The limited research examining the psychosocial experiences of young adults with CF indicates that other young adults lack awareness and understanding of CF. Using the Illness Perception Questionnaire, perceptions of CF were examined in individuals with CF aged 16 to 25 and two groups of same-aged peers: those who did, or did not, know someone with CF. ANOVA with pairwise comparisons revealed that individuals with CF perceived significantly fewer physical symptoms of illness and fewer emotional and practical consequences of CF than both groups of peers. Individuals with CF also perceived significantly more personal control and greater understanding of CF than peers without experience of CF. Implications for enhancing opportunities for social engagement and for the provision of social support for young people with CF are identified.

Reading Disability and Quality of Life Based on Both Self- and Parent-Reports: Importance of Gender Differences

Purpose: The aim of this study is to investigate self- and parent-rated quality of life (QoL) in children with a reading disability (RD) and the impact of comorbid psychopathology, with special focus on age and gender differences. Methods: Using the Dyslexia Differential Diagnosis Maastricht-Hungarian standard test, 127 children (aged < 18) were included in the RD group and 81 in the control group. To measure comorbid psychopathology, the Strengths and Difficulties Questionnaire (SDQ) was administered. To evaluate the children's QoL self- and parent-rated versions of the Measure of Quality of Life for Children and Adolescents (ILK) were used. Group differences in QoL and psychopathology were assessed using Mann-Whitney U-tests. Moderated mediational models were tested in which comorbid psychopathology mediated the relationship between group membership and self- and parent-rated QoL, which was dependent on gender. Child's age and parents' level of education were included as covariates. Results: The RD group showed lower QoL than the controls in several domains, according to the parent-report, while no differences between the two groups were found, according to self-report. In boys, results revealed conditional and indirect effects of group membership on self- and parent-rated QoL through comorbid psychopathology (-0.046, BCa 95% CI: -0.135 to 0.043 and 0.064, BCa 95% CI: 0.024-0.111, respectively) as well as a conditional direct effect of group membership on parent-reported (-0.098, BCa 95% CI: 0.012-0.184), but not self-rated, QoL. No relationship was found for girls. Conclusions: This study highlights the importance of measuring QoL and comorbid psychopathology in children with RDs from more sources and accounting for gender and age differences.

Toward a comprehensive assessment of functional outcomes in pediatric patients with brain arteriovenous malformations: the Pediatric Quality of Life Inventory

OBJECTIVE Brain arteriovenous malformations (bAVMs) are rare in pediatric patients but represent the most common cause of hemorrhagic stroke in this population. Pediatric patients demonstrate superior outcomes in comparison with adult patients with similar lesions and presentations. Most studies of clinical outcomes of pediatric bAVMs use the modified Rankin Scale (mRS), despite a lack of validation in pediatric patients. METHODS The authors interviewed the parents of 26 pediatric patients who underwent multimodality bAVM treatment and administered the Pediatric Quality of Life Inventory (PedsQL)-a well-validated tool for pediatric outcomes that quantifies performance in a physical, emotional, social, and school domains. They also reviewed clinical information from the patients' medical charts. Statistical analysis was performed using a log-transformed t-test, the Mann-Whitney exact test, the Kruskal-Wallis test, and Spearman correlation. In addition, the literature was reviewed for prior reports of clinical outcome of pediatric cases of bAVM. RESULTS The average PedsQL health-related quality of life score was 71 ± 24, with an average age at diagnosis of 12.5 years and an average follow-up period of 6.8 years. Seventeen patients (65%) presented with hemorrhage and 4 (15%) with seizures. PedsQL scores correlated strongly and at a statistically significant level (p < 0.001) with mRS, Pediatric Overall Performance Category (POPC), Pediatric Cerebral Performance Category (PCPC), and Glasgow Outcome Scale scores. Multivariate modeling validated special education, corrective devices, and cure status as significant predictors of PedsQL scores. Statistically significant risk factors for undergoing placement of a ventriculoperitoneal shunt included lower Glasgow Coma Scale motor scores on admission (p = 0.042), cerebellar location (p = 0.046), and nidus volume (p = 0.017). Neither treatment modality nor location statistically affected clinical outcomes at follow-up. CONCLUSIONS There have been few studies of long-term clinical outcomes of bAVM in pediatric patients, and previously published studies have used conventional metrics that have been validated in the adult population, such as the mRS. Although these metrics can serve as reasonable surrogates, an accurate understanding of overall health-related quality of life is contingent on utilizing validated toolsets, such as the PedsQL.

Symptom assessment in pediatric oncology: how should concordance between children's and parents' reports be evaluated?

BACKGROUND

Clinical evaluations in pediatric oncology are often triadic, involving children or adolescents, parents, and clinicians. However, few studies have evaluated the concordance between children's and parents' reports of symptom occurrence.

OBJECTIVES

The purposes of this study were to evaluate the concordance between children's and parents' symptom reports during the week of chemotherapy administration using 5 statistical approaches and determine which factors are associated with higher levels of dyadic concordance.

METHODS

Independent assessments of symptom occurrence were obtained from children and adolescents with cancer (n = 107) and their parents using the Memorial Symptom Assessment Scale 10-18. Concordance was assessed using (1) percentage of overall agreement, (2) Cohen κ coefficients, (3) McNemar tests, (4) positive percentage agreement, and (5) negative percentage agreement.

RESULTS

For each dyad, an average of 20 of the 31 symptom reports were concordant. Using children's reports as the "gold standard," parents rarely underestimated the children's symptoms. However, compared with children's reports, parents overestimated 7 symptoms. Advantages and disadvantages of each of the statistical approaches used to evaluate concordance are described in this article.

CONCLUSIONS

A variety of statistical approaches are needed to obtain a thorough evaluation of the concordance between symptom reports. Discordance was most common for symptoms that children refuted, particularly psychosocial symptoms.

IMPLICATIONS FOR PRACTICE

Clinicians need to interview children and adolescents along with their parents about the occurrence of symptoms and evaluate discrepant reports. Effective approaches are needed to improve communication between children and parents to improve symptom assessment and management.

A longitudinal examination of health-related quality of life in children and adolescents with spina bifida

OBJECTIVE

The current study examined (1) spina bifida (SB) youths' health-related quality of life (HRQOL) compared with nonclinical and chronic health condition (CHC) samples, (2) parent-child agreement regarding HRQOL, and (3) prospective changes in HRQOL.

METHODS

Child and parent-proxy reports of Pediatric Quality of Life were collected at two time waves (Time 1: N = 134, ages 8-15 years; Time 2: N = 109, ages 10-17 years) as part of a larger longitudinal study.

RESULTS

SB youth had statistically and clinically reduced physical HRQOL compared with the nonclinical and CHC samples at both time points. There were significant discrepancies between youth and parent-proxy reports of HRQOL; youth reported higher levels of physical and social HRQOL than parents. The majority of parent- and child-reported HRQOL domains remained stable, yet youth-reported social HRQOL increased over time.

CONCLUSIONS

Youth with SB are at risk for poor HRQOL. Examining modifiable condition and social-environmental predictors of youth HRQOL will be important in informing future interventions.

Factors influencing quality of life and disease severity in Hungarian children and young adults with cystic fibrosis

Background

The aim of our study was to evaluate factors affecting cystic fibrosis (CF) patients’ health-related quality of life (HRQoL) and to assess the level of agreement on HRQol between children and their parents.

Methods

Fifty-nine patients (mean age: 14.03 ± 4.81 years) from 5 Hungarian CF centres completed the survey. HRQoL was measured using The Cystic Fibrosis Questionnaire-Revised (CFQ-R). Parents were asked to fill out a questionnaire about their smoking habits, educational level and history of chronic illness. Disease severity was assessed using the physician-reported Shwachman-Kulczycki (SK) score system. Spirometry, Body Mass Index (BMI) percentile (pc), hospitalisation and Pseudomonas aeruginosa (PA) infection were examined as physiologic parameters of CF, and the impact of these factors on HRQoL was assessed. A multivariate regression analysis was performed to identify the most important factors affecting HRQoL. The level of significance was set to 0.05.

Results

Passive smoking and parental educational level and chronic diseases status did not have a significant impact on the patients’ HRQoL (p > 0.05). Significantly lower SK scores and spirometry values were found in low BMI pc patients (p < 0.001), in hospitalised (p < 0.01) and in PA-infected patients (p < 0.01), than in the adequate-weight, non-hospitalised and PA culture-negative subgroup. Lower CFQ-R scores were detected in hospitalised patients than in non-hospitalised patients in their Physical functioning domain. PA-infected patients had HRQoL scores that were significantly worse in the Body image (p < 0.01) and Respiratory symptoms (p < 0.05) domains than the PA culture-negative patients. Patients with a low BMI pc (<25^th BMI pc) had significantly lower scores in the Eating, Body image and Treatment burden domains, than the adequate-weight patients (>25^th BMI pc) (p < 0.01). A strong child–parent agreement was found in the Physical functioning domain (r = 0.77, p < 0.01).

Conclusions

Passive smoking, parental educational level and chronic diseases of parents do not affect the HRQoL of CF patients. In contrast, hospitalisation, PA infection and malnutrition have a significant and negative impact on patients’ HRQoL and the clinical severity of the disease. Parents and children were consistent in their scoring of symptoms and behaviours that were observable.

Quality of life and psychosocial well-being among children living with HIV at a care home in Southern India

This study was designed to evaluate the quality of life (QOL) of children living with HIV at an institutional care home in Bangalore, India. The Sneha Care Home is a unique residence that provides educational and community support with a focus on physical, nutritional, medical, and psychological care for orphans and vulnerable children. Cross-sectional health measures and interview data were collected from 97 residents including 52 boys and 45 girls between 5 and 12 years of age (mean age = 9). QOL was measured with the Pediatric Quality of Life 4.0 (PedsQL) Inventory. Caregivers perceived children to have an overall higher QOL than was self-reported by children (total score 83 vs. 78). Our findings indicated self-reported QOL decreased with age of the child, while caregiver-reported QOL increased with age, suggesting a need to ensure greater psychological support for older children. Physical measures showed the children's clinical severity of disease remained well controlled living in this residential, values-based care home.

Determinants of quality of life in children with asthma

BACKGROUND

HRQoL in children with asthma depends on multiple factors, among which asthma severity and level of control are believed to play a vital role. The determinants of the connection between asthma severity and asthma control with quality of life remain unclear.

AIMS

Primary aim of the study was to evaluate the HRQoL in children with asthma and to determine the factors that affect it.

MATERIALS AND METHODS

In total 504 children and one of their parents were recruited during a regular follow up visit in an outpatient asthma clinic. The measures used were the DISABKIDS smiley measure (DSmM), chronic generic measure-long form (DCGM-37) and the Condition-specific modules for asthma along with a special form for collecting demographic and clinical characteristics.

RESULTS

Three hundred fifteen children with mean age 5.35 years (Group A) and 189 with mean age 10.79 years (Group B), were recruited. Children with controlled asthma had significant higher mean score than the other asthma control groups (P < 0.001). Corticosteroid use, asthma severity, number of visits in doctor's office and lack of asthma control were significantly associated with the DCGM-37 scores as well as Impact Scale and Worry Scale. Lack of Asthma Control was the only factor that was associated with negative HRQoL in all the multiple regression models, controlling for the effect of the other covariates, in both age groups.

CONCLUSIONS

In conclusion, the evaluation of asthma HRQoL independently reflects the asthma control state and a dimension of its severity. These results highlight the need to modify asthma management strategy.

Implications of parent and child quality of life assessments for decisions about growth hormone treatment in eligible children

OBJECTIVE

To determine differences between parents and children in ratings of child health-related quality of life (HRQL) prior to growth hormone treatment.

METHOD

HRQL measures were collected from 144 children and their caregivers. Inclusion criteria were aged between 10 and 16 years, diagnosed with Turner's syndrome, acquired or idiopathic growth hormone deficiency (AGHD or IGHD) and eligible to begin human GH treatment (GHT), or non-growth hormone deficient (GHD) short stature.

RESULTS

Parents rated children to have poorer physical and psychosocial HRQL than children rated themselves. Differences depended on the measure used. Parents rated children with IGHD and non-GHD short stature better than children rated themselves, but they rated children with AGHD or Turner's much worse than children rated themselves in terms of physical but not psychosocial functioning.

CONCLUSIONS

Decisions to prescribe GHT should include children's perspectives of HRQL whenever possible. Differences between parents and children are most likely in conditions that involve more complex medical needs (AGHD and Turner's). Generic and disease-specific HRQL measures may vary in sensitivity to HRQL differences between groups. More work is required to evaluate HRQL among younger children.

The Methodological Challenges for the Estimation of Quality of Life in Children for Use in Economic Evaluation in Low-Income Countries

OBJECTIVES

The assessment of quality of life (QOL) in children has been underresearched in high- and low-income countries alike. This is partly due to practical and methodological challenges in characterizing and assessing children's QOL. This article explores these challenges and highlights considerations in developing age-specific instruments for children affected by HIV and other health conditions in Africa and other low-income settings.

METHODS

A literature search identified works that have 1) developed, 2) derived utilities for, or 3) applied QOL tools for use in economic evaluations of HIV interventions for children. We analyzed the existing tools specifically in terms of domains considered, variations in age bands, the recommended respondents, and the relevance of the tools to African and also other low-income country contexts.

RESULTS

Only limited QOL research has been conducted in low-income settings on either adults or children with HIV. A few studies have developed and applied tools for children (e.g., in Thailand, Brazil, and India), but none have been in Africa. The existing methodological literature is inconclusive on the appropriate width or depth by which to define pediatric QOL. The existing instruments include QOL domains such as "physical functioning," "emotional and cognitive functioning," "general behavior (social, school, home)," "health perception," "coping and adaptation," "pain and discomfort," "extended effects," "life perspective," and "autonomy."

CONCLUSIONS

QOL assessment in children presents a series of practical and methodological challenges. Its application in low-income settings requires careful consideration of a number of context-specific factors.

Utilization of patient-reported outcomes as a step towards collaborative medicine

Patient-reported outcomes (PROs) have been successfully developed for a variety of chronic respiratory diseases, such as asthma and cystic fibrosis (CF). They have recently been used to evaluate the efficacy of new medications and assess current patient functioning. Although regulatory bodies have favored PROs that measures symptoms, other domains of functioning, such as treatment burden, should be considered. This review examines current guidelines for the development and application of PROs in clinical trials, describes methods for selecting appropriate measures for paediatric populations, and presents a model incorporating PROs into clinical practice. Guidance on interpretation of these measures and graphic presentation of results are illustrated. PROs can serve as the link between the health care provider and patient to foster collaborative and personalized medicine. This model promotes greater patient responsibility, facilitates communication with providers, encourages shared decision-making, and enhances adherence.

Health priorities in adolescents with inflammatory bowel disease: physicians' versus patients' perspectives

OBJECTIVES

Adolescence is a tough age for patients with inflammatory bowel disease (IBD) because they transition from child to adult medicine. Although a better understanding of the experience of illness and therefore a better response to the patient's needs have often been stressed, no studies have yet investigated the paediatricians' insight into their IBD adolescent patients.

METHODS

A group of adolescents (ages 12-19) diagnosed as having IBD was administered a questionnaire listing 22 items of concern. They were asked to rank each item on a 5-point scale according to the degree of effect on the quality of their everyday life. The same questionnaire was administered to a group of paediatricians experienced in treating IBD and to a group of paediatric residents. Paediatricians and residents were asked to estimate how much each item would affect the quality of an average patient's life, according to the same scale. The questionnaire was also used in a face-to-face approach, asking a paediatrician to apply the estimation to an individual patient, instead of an average imaginary one.

RESULTS

Fifteen paediatric gastroenterologists, 11 paediatric residents, and 28 patients (female:male = 16:12; median age 16.3 years) took part in the study. The majority of patients experienced Crohn disease (17 vs 11 with ulcerative colitis). We found only 6 items overlapping when comparing the top 10 items ranked by patients and paediatricians. The patients' number 1 concern occupies the ninth position in the paediatricians' list. The number 1 item for paediatricians is not even mentioned in the patients' top 10 list. Overall, both paediatricians' and residents' rankings were significantly higher than those given by patients.

CONCLUSIONS

We found a significant misalignment in the estimation of health concerns between IBD adolescent patients and their paediatricians. A better insight into IBD patients' worries and concerns is crucial for the improvement of the patient's quality of life and disease outcome.

Future plans and social/recreational activities of youth with special health care needs: the implications of parental help in completing surveys

BACKGROUND

A major focus of the literature on youth with special health care needs (YSHCN) is the transition to adult health care. As perceptions of disability are a product of interactions between youth and their environment, it is important to understand youth's needs and experiences beyond health care. Few studies have addressed social/recreational activity participation and future plans and none have included parent/caregiver help in survey completion as a potential factor impacting responses.

OBJECTIVES

We describe activity participation and identification of future plans among YSHCN and examine the impact of receiving parent/caregiver assistance to complete a survey on these responses. Implications for research, policy, and practice affecting programs serving and providing transition assistance for YSHCN are discussed.

METHODS

Data are from a survey of YSHCN conducted during Alabama's 2010 Title V Maternal and Child Health Needs Assessment. Analyses included descriptive statistics, bivariate analysis, and multivariable logistic regression.

RESULTS

Youth who received help completing the survey were less likely to report participating in certain social/recreational activities and key future plans, including hobbies, getting married, having children, and working for pay.

CONCLUSIONS

For YSHCN, parent/caregiver assistance to complete a survey is a critical consideration in analyses and interpretation of results. Whether, how much, and what type of help received may represent a more objective proxy measure of perceptions of condition severity or impact on abilities than do self-reported ratings of these factors. Our results also raise questions about the distinctions between youth and parent/caregiver perceptions of independence, participation, and potential.

Quality of life in Hungarian patients with cystic fibrosis

Introduction: Cystic fibrosis is a progressive multisystemic disease which affects the quality of life of patients. Aim: The aim of the study was to evaluate quality of life in Hungarian patients with cystic fibrosis. Methods: Validated Hungarian translation of The Cystic Fibrosis Questionnaire – Revised was used to measure quality of life. Clinical severity was determined on the basis of Shwachman–Kulczycki score. Lung function was measured using spirometry. Results: 59 patients were included from five centres in Hungary. The relationships between 8–13 year-old children self-report and parent proxy report was 0.77 (p<0.001) in physical functioning, 0.07 (p<0.001) in emotional functioning, 0.51 (p<0.001) in eating, 0.21 (p<0.001) in treatment burden, 0.54 (p<0.001) in body image, 0.49 (p<0.001) in respiratory symptoms and 0.40 (p<0.001) in digestive symptoms domains. Conclusions: In contrast to physical domains weak correlations were observed between answers obtained from children and their parents in psychosocial domains. The perception of both patients and their parents should be assessed when measuring quality of life in paediatric patients with cystic fibrosis. Orv. Hetil., 2013, 154, 784–791.

Health-related quality of life in children and adolescents with cystic fibrosis: convergent validity with parent-reports and objective measures of pulmonary health

OBJECTIVE

This study examined the convergent validity of health-related quality of life (HRQOL) reported by patients with cystic fibrosis compared with their parents' reports and objective pulmonary measures across 3 time points.

METHODS

Ninety-two children (8-13 years) and adolescents (14-18 years) with cystic fibrosis and their parents completed Cystic Fibrosis Questionnaires to examine concordance with Wisconsin chest x-ray (WCXR) scores and pulmonary function tests, for example, forced expiratory volume at 1 second (FEV1), and parent-child/adolescent concordance across multiple HRQOL domains. Concordance was analyzed relative to patient age and gender.

RESULTS

Parent-reports were closely aligned with WCXR scores, whereas patient reports were more closely aligned with FEV1. Adolescents and parents of both age groups had more HRQOL domains concordant with pulmonary health measures than did child self-reports. Parent-child concordance was inversely related to child age, particularly with male adolescents. Children generally reported better HRQOL than parents. Male adolescents and their parents were more likely to have significantly discordant HRQOL scores than female adolescents and their parents. Male and female adolescents reported higher HRQOL than their parents reported for all but vitality and health perception domains. Younger male children showed concordance with their parents on 5 of 7 domains.

CONCLUSIONS

Parent-child/adolescent discordance on HRQOL was consistent with normative child development expectations. Findings underscore the value of enlisting perspectives from parents as well as children regarding HRQOL.

Transplanting the adolescent cystic fibrosis patient: can we do it?

Bilateral lung transplantation remains a treatment for end-stage cystic fibrosis (CF) lung disease when there is no further medical or surgical treatment available. The aim of lung transplantation is to improve patient life expectancy. The consensus view that lung transplantation extends life in children has been challenged. However, challengers have faced alternative explanations of their finding and it is largely accepted that lung transplantation in the adolescent patient population is an important treatment modality. The goal of this article is to address these concerns and assist with developing creative approaches to this known challenging subset of patients. The main focus of this article will be to discuss the looming question: what existing evidence or best practice insights could improve bilateral lung transplantation outcomes for adolescent patients with end-stage CF?

Prospective study of health-related quality of life for children with brain tumors treated with proton radiotherapy

PURPOSE

We describe the health-related quality of life (HRQoL) of a cohort of children with brain tumors treated with proton radiotherapy.

PATIENTS AND METHODS

We recruited 142 pediatric patients with brain tumors (age 2 to 18 years) and parents of such patients treated with proton radiation at Massachusetts General Hospital from 2004 to 2010. HRQoL was assessed using the PedsQL core, brain tumor, and cancer modules (range, 0 to 100). Assessments took place during radiation and annually thereafter. We examined correlations of HRQoL with disease, treatment, and cognitive and behavioral data.

RESULTS

Overall reports of HRQoL during treatment were 74.8 and 78.1 for child self-report (CSR) and 67.0 and 74.8 for parent proxy report (PPR) for the core and brain tumor modules, respectively. PPR demonstrated lower HRQoL scores than CSR, but the two were highly correlated. Higher HRQoL scores were significantly associated with Wechsler Full Scale Intelligence Quotient scores (administered via the age-appropriate version) and better scores on two behavioral measures. Disease type also correlated with PPR core total HRQoL score at the beginning of treatment: medulloblastoma or primitive neuroectodermal tumors, 57.8; germ cell tumors, 63.5; ependymoma or high-grade glioma, 69.8; low-grade glioma, 71.5; and other low-grade neoplasms, 78.0 (P = .001). Craniospinal irradiation and chemotherapy were negatively correlated with HRQoL.

CONCLUSION

This is the first study to our knowledge of HRQoL in a cohort of children with brain tumors treated with proton radiation. This prospective study demonstrates the effect of disease type and intensity of treatment on HRQoL. It further suggests that where CSR is not possible, PPR is appropriate in most circumstances.

The proxy problem anatomized: child-parent disagreement in health related quality of life reports of chronically ill adolescents

Background

Discrepancy between self-reports and parent-proxy reports of adolescent health-related quality of life (HRQoL) has been repeatedly acknowledged in the literature as the proxy problem. However, little is known about the extent and direction of this discrepancy. The purpose of this study is to explore to what extent and in what direction HRQoL self-reports of adolescents with chronic conditions and those of their parents differ.

Methods

A cross-sectional survey was conducted among adolescents suffering from chronic conditions and their parents. Socio-demographic and disease-related characteristics were collected and information about consequences of the chronic condition was assessed. HRQoL was measured with KIDSCREEN-10 and DISABKIDS condition generic measure (DCGM-10). Agreement was analysed through defining a threshold of agreement based on half of the standard deviation of the HRQoL score with the highest variance. Agreement occurred if the difference between adolescent and parent scores was less than or equal to half of the standard deviation. Intra-class correlation coefficients and Bland-Altman plots were also computed. The characteristics associated with direction of disagreement were statistically tested with one-way ANOVA and Chi-square tests.

Results

584 paired HRQoL scores were obtained. Ratings from both adolescents and parents were high, compared to European norm data. Differences between adolescents and parents were statistically significant, yet relatively small. Disagreement existed in both directions: in 24.5% (KIDSCREEN-10) and 16.8% (DCGM-10) of the cases adolescents rated their HRQoL lower than did their parent, while in 32.2% (KIDSCREEN-10) and 31.7% (DCGM-10) of the cases the opposite was true. Adolescent's age, educational level and type of education, parent's educational level, number of hospital admissions and several other disease-related factors influenced direction of disagreement.

Conclusions

In a reasonable proportion of cases the adolescent and parent agreed on the adolescent's HRQoL (43-51% of the cases) and most disagreement tended to be minor. Thus, the proxy problem may be smaller than presented in the literature and its extent may differ per population. As adolescents are expected to become partners in their own health care, it is recommended to focus on adolescents' own perceptions of HRQoL.

Health-related quality of life in cystic fibrosis

PURPOSE OF REVIEW

To review the contribution of various therapeutic interventions on both longevity and quality of life in cystic fibrosis patients.

RECENT FINDINGS

Long-term survival in cystic fibrosis has increased markedly in the past 25 years, largely due to a robust clinical trials program carried out at Cystic Fibrosis Foundation accredited clinical centers in the United States and similar organizations worldwide. Cystic fibrosis patients are recommended complex, time-intensive daily therapies that are often difficult for families and patients to sustain long-term. Recently, attention to the perceived value of a particular therapy on a patient's well being is recognized as important for individualizing therapeutic regimens that provide maximal clinical benefit and are more likely to be adhered to long-term by the patient. Cystic fibrosis care is in a new era in which patient-related outcomes (PROs) for the assessment of health-related quality of life (HRQOL) are regarded with equal importance to medically beneficial therapies.

SUMMARY

Numerous advances in the clinical care of cystic fibrosis have led to improved survival, although definitive correction of the abnormal cystic fibrosis transmembrane regulator protein function remains elusive. Patients struggle to maintain rigorous, time-intensive therapeutic regimens, whereas clinicians strive to identify which interventions preserve quality of life. Cystic fibrosis patients depend on their caregiver's ability to assess both the medical benefit and the contribution to quality of life that therapeutic regimes bring to their disease. Caregivers, in turn, need measures of HRQOL in order to prioritize the various therapeutic interventions that are at their disposal in order to provide not just longevity, but meaningful quality of life.

The burden of disease in pediatric non-cystic fibrosis bronchiectasis

BACKGROUND

The burden of disease in children with non-cystic fibrosis (non-CF) bronchiectasis is unknown. Our study aimed to identify the determinants of quality of life (QOL) and parental mental health in this group of patients and their parents and to evaluate the effect of exacerbations on these parameters.

METHODS

Parents of 69 children (median age 7 years) with non-CF bronchiectasis prospectively completed two questionnaires (parent-proxy cough-specific quality of life [PC-QOL] and the Depression, Anxiety, and Stress Scale [DASS]) at stable and exacerbation states. Data on clinical, investigational, and lung function parameters were also collected.

RESULTS

During the stable state, the median interquartile range (IQR) PC-QOL score was 6.5 (5.3-6.9) and the DASS 21-item questionnaire score was 6 (0-20). Being of a young age correlated with a worse QOL (r(5) = 0.242, P = .04) but radiologic extent, lung function, underlying cause, environmental tobacco smoke exposure, and chronic upper-airway disease did not influence these scores. Exacerbations caused significant worsening in the PC-QOL scores (median [IQR], 4.6 [3.8-5.4]; P = .001) and DASS scores (median [IQR], 22 [9-42]; P < .001; 38% with elevated anxiety, 54% with abnormal depression/stress scores during exacerbation). The presence of viral infection, hypoxia, and hospitalization did not influence the exacerbation PC-QOL and DASS scores.

CONCLUSIONS

There is a significant burden of disease, especially during exacerbation, on parents of children with bronchiectasis. Prevention, early detection, and appropriate treatment of exacerbations are likely to reduce psychologic morbidity in this group.

Transitioning care of an adolescent with cystic fibrosis: development of systemic hypothesis between parents, adolescents, and health care professionals

This qualitative study explored the experience of parents and adolescents living with cystic fibrosis prior to the transfer of the adolescent's care from a pediatric to an adult health care facility. Semistructured interviews were conducted with seven families receiving care from a specialized cystic fibrosis clinic; parents and adolescents were interviewed separately, followed by a group interview with members of a health care team comprising eight professionals from the clinic. Interviews were analyzed through a systemic lens which accounts for interaction and reciprocity in relationships. The parents' experience was marked by suffering and uncertainty that remained unexpressed to the health care team, even though team members had known the family since the child was first diagnosed. Findings led to identifying a systemic hypothesis that accounted for the interactions and relational processes between parents and the health care team. This hypothesis may guide the development of systemic family nursing interventions that target this complex, relational, transition process.

Avaliação da qualidade de vida de pacientes com fibrose cística por meio do Cystic Fibrosis Questionnaire

OBJETIVO: Avaliar a qualidade de vida (QV) de pacientes com fibrose cística (FC) acompanhados em um centro universitário de referência em atendimento a FC. MÉTODOS: Estudo transversal com a aplicação do Cystic Fibrosis Questionnaire (CFQ) e escore de Shwachman em pacientes com FC entre abril de 2008 e junho de 2009. RESULTADOS: Participaram 75 pacientes, com média de idade de 12,5 ± 5,1 anos (variação: 6,1-26,4 anos). Os pacientes foram divididos em três grupos de acordo com a idade: grupo I (< 12 anos), II (12-14 anos) e III (> 14 anos). As pontuações mais altas e mais baixas no CFQ foram para o domínio alimentação do grupo III (89,3 ± 16,2) e para o domínio social no grupo II (59,5 ± 22,3), respectivamente. Houve uma diferença significativa no domínio tratamento entre os grupos III e I (p = 0,001). Pacientes com escore de Shwachman < 70 apresentaram diferenças significativas em relação aos domínios social (grupo I; p = 0,045), respiratório (grupo II; p = 0,053) e digestivo (p = 0,042) quando comparados aqueles com escores > 70. No grupo III, não se observou associação entre gravidade e QV. Nos grupos I e II, não se observou diferenças entre os pacientes com VEF1 < 80% do previsto e os demais pacientes em todos os domínios do CFQ. Entretanto, no grupo III, as médias dos pacientes com VEF1 < 80% do previsto foram significativamente menores nos domínios físico (p = 0,012), imagem corporal (p = 0,031), respiratório (p = 0,023), emocional (p = 0,041) e papel social (p = 0,024). CONCLUSÕES: A avaliação da QV em pacientes com FC é importante, pois contribui para uma melhor aderência ao tratamento.

The effect of parental mental health on proxy reports of health-related quality of life in children with sickle cell disease

BACKGROUND

The objectives of this study were to evaluate factors that influence agreement between parent-proxy and child self-report of health-related quality of life (HRQL) in sickle cell disease. We hypothesized that the mental health of the parent, parental HRQL and child characteristics would affect agreement.

PROCEDURE

In a cross-sectional study of children with sickle cell disease, HRQL of the child and the parent's HRQL and mental health were assessed. The effect of parent and child characteristics on agreement between parent-proxy and child self-report of HRQL were determined.

RESULTS

Rates of agreement between parent-proxy and child self-report of HRQL ranged between 42% and 49%. Parents with increased symptoms of distress had an increased odds of reporting a worse physical (Odds Ratio (OR) 1.12) and psychosocial HRQL (OR 1.10) compared to the child's self-report. Severe sickle cell disease was associated with an increased odds of the parent reporting the child's physical HRQL was worse, (OR 4.68) compared to the child's self-report.

CONCLUSIONS

Greater symptoms of distress in the parent are associated with worse parent-proxy report of the child's HRQL. Severe sickle cell disease is associated with greater disagreement between parent-proxy and child self-report of HRQL. These findings broaden our understanding of factors that influence proxy-reporting of a child's HRQL.

Dornase alfa improves the health-related quality of life among Brazilian patients with cystic fibrosis--a one-year prospective study

SUMMARY BACKGROUND

Health-related quality of life (HRQOL) measurements provide valuable information about the psychological and social impact of treatment on patients with cystic fibrosis (CF). This study evaluated the HRQOL of Brazilian patients with CF and assessed the changes in HRQOL domains over 1 year after dornase alfa (Pulmozyme) introduction.

PATIENTS AND METHODS

One hundred fifty-six stable patients with CF and 89 caregivers answered the Portuguese-validated version of the Cystic Fibrosis Questionnaire-Revised (CFQ-R) at baseline (T(0)), and at 3 (T(1)), 6 (T(2)), 9 (T(3)), and 12 (T(4)) months of follow-up. Eighteen patients were excluded because they did not fulfill the inclusion criteria. The patients were analyzed in two groups: those aged 6-11 years and those aged 14 years and older. ANOVA for observed repeated results and the last observation carried forward (LOCF) method for missing data were used for the statistical analysis.

RESULTS

After 1 year of follow-up, there was significant improvement in respiratory symptoms (T(4) - T(0) = 8.1; 95% confidence interval (95% CI) = [2.1;14.0]; effect size (ES) = 0.35; P < 0.001), Emotional Functioning (T(4) - T(0) = 5.6; 95% CI = [1.1;10.1]; ES = 0.31; P < 0.05), Social Functioning (T(4) - T(0) = 6.0; 95% CI = [1.3;11.7]; ES = 0.31; P < 0.05), Body Image (T(4) - T(0) = 11.9; 95% CI = [4.1;19.7]; ES = 0.42; P < 0.05), and Treatment Burden (T(4) - T(0) = 5.3; 95% CI = [0.3;10.3]; ES = 0.24; P < 0.05) domains in the younger group. A significant improvement in Role Functioning (T(4) - T(0) = 6.1; 95% CI = [1.1;11.1]; ES = 0.40; P < 0.05), Body Image (T(4) - T(0) = 12.6; 95% CI = [3.5;21.7]; ES = 0.46; P < 0.05), and Weight (T(4) - T(0) = 11.7; 95% CI = [1.8;21.6]; ES = 0.40; P < 0.05) was obtained in the older group. The caregivers' CFQ-R showed improvements in the Digestive Symptoms (T(4) - T(0) = 5.5; 95% CI = [1.5;9.4]; ES = 0.30; P < 0.05), Respiratory Symptoms (T(4) - T(0) = 7.6; 95% CI = [3.9;11.4]; ES = 0.48; P < 0.05), and Weight (T(4) - T(0) = 10.1; 95% CI = [1.6;18.6]; ES = 0.26; P < 0.05) domains.

CONCLUSION

The introduction of dornase alfa improved the HRQL of the patients with CF during the first year of treatment.

Quality of life in rare genetic conditions: a systematic review of the literature

Quality of life (QoL) refers to an individual's sense of overall well-being encompassing physical, psychological, emotional, social, and spiritual dimensions. Although genetics healthcare providers strive to promote patient well-being, and the term QoL is often invoked to refer to this outcome, there is lack of clarity as to what actually constitutes QoL from the patient's perspective. This systematic literature review aims to summarize and integrate research findings to help elucidate how healthcare providers can more effectively enhance the QoL of patients affected with rare genetic conditions. Eligible studies were those that measured QoL as a primary outcome variable using a validated, multi-dimensional scale. Detailed criteria were used to rate quality of design, methodology, and analytic rigor. Fifty-eight studies were selected for inclusion in the review, and a narrative synthesis of the data was performed. A central theme emerging from the literature is that, although genetic conditions have the potential to have significant negative consequences for individuals' lives, having a genetic condition does not necessarily entail poor QoL. Evidence demonstrates that factors beyond the physical manifestations of the disease, such as psychological well-being, coping, and illness perceptions, influence QoL and may serve as potent targets for intervention. The field of research on QoL in rare genetic conditions will be advanced by uniting around a clear conceptualization of QoL and using more rigorous methodology with comprehensive measures of global QoL.

Quality of life and psychosocial functioning of HIV infected children

OBJECTIVE

To assess the quality of life (QOL) and the psychosocial problems of HIV infected children.

METHODS

The present study was a comparative, cross-sectional survey conducted in the clinic of a tertiary care hospital in north India from July-December 2007. Children suffering from cystic fibrosis (CF) were chosen as a comparison group. Children (3) 6 yr of age with HIV infection or Cystic Fibrosis, with no acute illness at the time of survey were included in the study. Quality of life of the enrolled children was assessed by using the Pediatric Quality of Life Inventory (PedsQL). Pediatric Symptom Checklist (PSC) was used for assessing the psychosocial problems in the enrolled children.

RESULTS

Forty one HIV infected and 30 children with cystic fibrosis were enrolled. According to child self -report in the PedsQL 4.0, the difference of perceived physical health status between the two study groups was statistically significant (p=0.04), with HIV infected children demonstrating a better QOL in this domain. A significantly greater number of children with cystic fibrosis (8/30 or 26.67%) suffered from psychosocial problems as compared to HIV children (3/41 or 7.32%) [p=0.026].

CONCLUSIONS

The quality of life and psychosocial functioning is reasonably good in children with HIV infection. Thus, we should strive to maintain and optimize the overall quality of life of these children so that they can have a productive and meaningful future.

A breath biofeedback computer game for children with cystic fibrosis

The authors sought to develop and test a breath-controlled video game using a digital spirometer that, by providing visual breath biofeedback, could promote awareness of breathing techniques in children with cystic fibrosis (CF). To assess improvement in game performance during hospitalizations for CF exacerbations, the authors conducted a trial on 10 inpatients. Subjects had at least five 15-minute exposures to a breath biofeedback game that challenged them to track a moving target using their breath. Subjects reacted positively to the breath tracking challenge. Repeated-measures analysis of variance of a tracking fidelity statistic showed improvement in eye-breath coordination over 5 sessions ( P = .026). It was concluded that an electronic breath game is safe and can improve breath awareness among children with CF. This technology could also contribute to awareness of respiratory symptoms and foster social ties among CF patients.

Parent- versus child-reported functional health status after the Fontan procedure

OBJECTIVE

We sought to compare perceptions of functional health status between children who had undergone a Fontan procedure and their parents.

METHODS

Fontan procedure survivors 10 to 18 years of age were included in the study if the child completed the Child Health Questionnaire (CHQ) and the parent completed the parent form to assess the child's functional health status. Comparisons were made between raw domain scores for the parent- and child-completed CHQs.

RESULTS

Between March 2003 and April 2004, 1078 Fontan survivors were screened. Of the 546 eligible and consented patients, 354 were 10-18 years of age and 328 parent/child pairs completed the CHQs. Parents reported significantly lower scores (worse functioning) for their children than the children reported for themselves in the domains of physical functioning (P < .01), impact on school or activities from emotional and behavioral problems (P < .01), impact on school or activities from physical health issues (P < .01), general behavior (P < .01), mental health (P < .01), self-esteem (P < .01), and general health perceptions (P < .01). No significant differences were noted for the domains of bodily pain, family cohesiveness, or family activities. For the physical functioning domain, factors contributing to lower scores for parent versus child reports included pulmonary artery anomalies and fenestration at the time of the Fontan operation. Lower parent-reported scores also were associated with more noncardiac health problems in the child.

CONCLUSIONS

Parents' perceptions of the functional health status of their children after the Fontan procedure were worse than the children's perceptions.

Pain in children and adults with cystic fibrosis: a comparative study

Pain is a potential complication of cystic fibrosis (CF), but its consequences in daily life and other issues of pain management are not yet clearly understood. We undertook a comparative study of children and adults with CF to assess the prevalence of pain symptoms, their characteristics and treatment, their impact on daily quality of life, and the occurrence of procedural pain. The study included 73 children (1-18 years) and 110 adults (18-52 years); 59% of the children and 89% of the adults reported at least one episode of pain during the previous month. Pain was significantly more intense and lasted significantly longer among adults, but its rate and recurrence did not differ significantly between the two populations and were not related to the severity of CF. The most prevalent locations were the abdomen for children, and the back, head, and chest for adults. Although pain significantly limited physical activity, only 15% of patients reported that it caused absenteeism, and 27% reported that it negatively affected their family life. The mean pain intensity rates on a visual analog scale for the episode that had caused the greatest pain during the past month were 4.9 (2) (mean [SD]) for children and 6 (2) for adults; however, only 40% and 50%, respectively, of those with pain reported the use of analgesic treatment, mainly paracetamol (acetaminophen). At least one episode of procedural pain during the previous month was reported by 85% of children and 78% of adults. Our study demonstrates the high incidence of undertreated pain in CF patients throughout their lives.

Agreement between children with cancer and their parents in reporting the child's health-related quality of life during a stay at the hospital and at home

BACKGROUND

Although parent-child agreement is widely studied in the paediatric clinical sample, no study has compared parent-child agreement during home and hospital stays. We aimed to determine the level of agreement in reports of health-related quality of life (HRQoL) between parents of children with cancer and the children themselves during a stay in the hospital and a stay at home.

METHODS

The sample consisted of 28 children, aged 9-18 years old, hospitalized and treated for cancer in a Children's University Hospital in France. The child's HRQoL was assessed by the parent and child versions of the Child Health Questionnaire. Parent-child agreement was estimated by the intraclass correlation coefficient. Potential predictors influencing the parent-child agreement were investigated.

RESULTS

For both locations of stay, parent scores from the HRQoL survey were lower than those for their children for all domains, except for the general behaviour during the home stay. Scores for both parents and children, for all domains, were lower during the hospital than the home stay. The parent-child agreement was better for mental health, self-esteem, general health and family activities during the hospital stay (range 0.32-0.66), but was better for physical function, role/physical and general behaviour during the home stay (range 0.45-0.71). Few predictors of parent-child agreement were found.

CONCLUSIONS

Agreement between parents and their children who have cancer in reporting the child's HRQoL differed by location of stay. For the home stay, the agreement was better for domains related to the child's physical life, but for the hospital stay, it was better for domains related to the child's behaviour/psychological life.

Agreement was not found in adolescents' quality of life rated by parents and adolescents

OBJECTIVE

Limited evidence examines agreement between the ratings of adolescents' health-related quality of life (HRQOL) by parents and adolescents especially accounting for measurement properties. This study aimed to test whether agreement exists between the dyads using a methodology of measurement invariance.

STUDY DESIGN AND SETTING

We conducted a telephone survey to collect data from parents and their adolescents enrolled in Florida's Children's Medical Services (376 pairs) using the PedsQL 4.0. We used multi-group confirmatory factor analysis to test measurement invariance, including configural (equivalent HRQOL construct), metric (equivalent item-domain associations), scalar (equivalent starting value of ratings), and residual (equivalent nonsystematic measurement errors of ratings) invariance. We also investigated correlates of discrepancies in the dyadic ratings.

RESULTS

There were equivalent HRQOL constructs and item-domain associations between the dyads. However, some items show different starting values and nonsystematic errors in the dyadic ratings. After adjusting for noninvariant items, adolescents reported significant higher HRQOL scores than parents in all domains (P<0.05). Parents' rating of adolescents' health significantly contributed to discrepancies in the dyadic ratings (P<0.05).

CONCLUSIONS

Adolescents rated HRQOL higher than their parents. This discrepancy was associated with severe health conditions. Without assuring measurement invariance, comparisons of the dyadic HRQOL ratings can be misleading.

Parent-child agreement across child health-related quality of life instruments: a review of the literature

AIM

To systematically review the literature published since 1999 on paediatric health-related quality of life (HRQL) in relation to parent-child agreement.

METHODS

Literature searches used to identify studies which evaluated parent-child agreement for child HRQL measures.

RESULTS

Nineteen studies were identified, including four HRQL instruments. The Pediatric Quality of Life Inventory (PedsQL) was most commonly used. Differences in parent-child agreement were noted between domains for different measures. The impact of child and parent characteristics were not consistently considered; however parents of children in a nonclinical sample tended to report higher child HRQL scores than children themselves, while parents of children with health conditions tended to underestimate child HRQL.

CONCLUSION

Despite increasing numbers of studies considering children's HRQL, information about variables contributing to parent-child agreement levels remains limited. Authors need to consistently provide evidence for reliability and validity of measures, and design studies to systematically investigate variables that impact on levels of parent-child agreement.

Parents of children with cystic fibrosis: how they hope, cope and despair

BACKGROUND

Cystic fibrosis is a chronic, life-threatening illness. Coping, vicarious hope and vicarious despair are constructs that may explain why some children and parents adjust well to cystic fibrosis, while others adjust poorly. Vicarious hope refers to parent expectations that desirable things will occur in their child's future, whereas vicarious despair refers to parent expectations that undesirable things will occur in their child's future. The aims of this study were: (1) to examine parent coping strategies and associations with child and parent adjustment to cystic fibrosis; (2) to investigate the effects of vicarious hope and vicarious despair on coping, parent adjustment and child adjustment; and (3) to examine distinctions between coping, vicarious hope and vicarious despair.

METHODS

Participants were 35 parents of children with cystic fibrosis.

RESULTS

Self-blame and behavioural disengagement were coping strategies associated with child and parent maladjustment. Social support predicted less parental emotional impact. Vicarious hope and vicarious despair predicted child mental health, parent anxiety and parent emotional impact.

CONCLUSIONS

Results indicate that vicarious hope and vicarious despair are distinct constructs from coping. Interventions directed at parent coping, vicarious hope and vicarious despair are implicated.
