Computerised paediatric asthma quality of life questionnaires in routine care

Background

Asthma quality of life questionnaires are not readily incorporated into clinical care. We therefore computerised the Paediatric Asthma Quality of Life Questionnaire (standardised) (PAQLQ(S)) and the Paediatric Asthma Caregivers Quality of Life Questionnaire (PACQLQ), with a colour‐coded printed graphical report.

Objectives

To (a) assess the feasibility of the electronic questionnaires in clinical care and (b) compare the child''s PAQLQ scores with the parent''s score, physician''s clinical score and spirometry.

Methods

Children with asthma were given a clinical severity score of 1–4 (increasing severity) and then completed the PAQLQ(S) electronically (scores 1–7 for increasing quality of life in emotional, symptoms and activity limitation domains) followed by spirometry and physician review. Parents completed the PACQLQ. Inclusion criteria required fluent Hebrew and reliable performance of spirometry. Children with additional chronic diseases were excluded.

Results

147 children with asthma aged 7–17 years completed PAQLQs and 115 accompanying parents completed PACQLQs, taking 8.3 (4.3–15) and 4.4 (1.5–12.7) min, respectively (mean (range)). Graphical reports enabled physicians to address quality of life during even brief visits. Children''s (PAQLQ) and parents'' (PACQLQ) total scores correlated (r = 0.61, p<0.001), although the children''s median emotional score of 6.3 was higher than their parents'' 5.7 (p<0.001), whereas median activity limitation score was lower than their parents'': 5.0 and 6.8, respectively (p<0.001). No correlation was found with physician''s clinical score or spirometry.

Conclusions

Electronic PAQLQs are easy to use, providing additional insight to spirometry and physician''s assessment, in routine asthma care. Future studies must assess impact on asthma management.     

General and disease-specific scales in children with asthma and their parents

Objective

To investigate and compare the efficiency of general and disease-specific life quality scales in children with asthma.

Methods

Children with asthma, and their parents completed the Childhood Asthma Control Test (C-ACT), Pediatric Asthma Quality of Life Questionnaire (PAQLQ), Pediatric Quality of Life Inventory (PedsQL), and also underwent spirometry.

Results

82 children (55 males) with a median (IQR) age of 10.1 (8.9-10.5) years were included. C-ACT, PAQLQ and PedsQL child scores were significantly higher in children with controlled asthma.

Conclusions

Quality of life in children, assessed using diseasespecific quality of life measures, is better for children with good asthma control.

     

Quality of life in childhood asthma: use of the Paediatric Asthma Quality of Life Questionnaire in a Swedish sample of children 7 to 9 years old

To validate a Swedish translation of the Paediatric Asthma Quality of Life Questionnaire (PAQLQ) and to study determinants of asthmatic children's quality of life, seventy-one 7-9-y-old children and their families were approached. Sixty-one children (86%) participated, 36 boys and 25 girls: 11 children with mild, 40 with moderate and 10 with severe asthma. The mean age was 8.7 y. Most commonly restricted activities during the week preceding the investigation were running (74%), gymnastics (30%), walking uphill (26%), playing football (20%) and shouting (13%). Parental rating of symptoms (Spearman's rho = -0.40, p = 0.001), percentage of expected peak flow rate (PEFR) (rho = 0.30, p = 0.009) and physicians' grading (mild, moderate and severe asthma, p = 0.047) all correlated significantly with PAQLQ scores. Younger children reported more impairment of QoL, as did children of parents not sharing household. Sex or presence of eczema or rhinoconjunctivitis did not significantly affect the scores. Children suffering from food allergy scored less impairment of QoL. The instrument was easy to administer, was well accepted by the children and had acceptable internal consistency.     

The Paediatric Asthma Caregiver's Quality of Life Questionnaire in Swedish parents

With the Paediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ), parents grade impaired activities (5 items) and emotional concern (8 items) from 1 to 7 regarding how much their own quality of life (QoL) has been affected by the disease of their child during the last week. The questionnaire was translated into Swedish. To test the feasibility and validity of the Swedish version, 71 asthmatic children and their families were approached. Sixty-one families (86%) participated. The mean age of the children was 8.7 y. Parental grading of symptoms (Spearman's rho = 0.637, p < 0.001), the asthma-specific QoL of the child (rho = 0.359, p = 0.002) and gradings of asthma from medical records (mild asthma median score 6.69, moderate 6.27 and severe 5.12, p = 0.001) were all related to overall PACQLQ scores. The sex of the child, the presence of other diseases related to allergy, peak flow rate (PEFR) and socio-economic level did not affect the scores. Lower scores in the emotional domain were seen in parents of children on steroids (p = 0.049). The distribution of scores was heavily skewed towards the positive end of the scale, leading to limited power to discriminate among parents of children with mild asthma. The instrument had good internal consistency and was well accepted by the parents.     

Pediatric asthma quality of life questionnaire (PAQLQ): Validation among asthmatic children in Thailand

Quality of life (QoL) is an important consideration among asthma sufferers. The Pediatric Asthma Quality of Life Questionnaire (PAQLQ) is one of the most widely used instruments for measuring health-related QoL in children with asthma. The standardized version of PAQLQ contains 23 questions in three domains, i.e., activity limitation, symptoms and emotional function. The objective of this study was to validate the Thai-translated version of the PAQLQ. The study design consisted of a five-week single cohort study. Patients recorded symptoms, and peak expiratory flow rate (PEFR) each morning and evening during the first and fifth week of the study in asthma diary. At each clinic visit, a trained-interviewer administered the PAQLQ and performed spirometric measurements. Fifty-one children, ages between 7 and 17 yr participated in the study. Scores from the asthma diary were used to classify patients into stable vs. unstable groups. The construct validity of the questionnaire was confirmed in both cross-sectional and longitudinal studies by demonstrating correlations between various PAQLQ domains with clinical asthma parameters (asthma diary, beta-agonist use and PEFR). There was high internal consistency for scores of the three domains (Cronbach's alpha-coefficient = 0.83-0.95). For those with stable asthma, the reliability of PAQLQ was good for the rating scale (intra-class correlation coefficient--ICC = 0.84) and for total score (alpha = 0.97) indicating high reproducibility of the PAQLQ. The significant difference of changes QoL scores between stable and unstable groups was observed in all domains. We conclude that the Thai version of PAQLQ is valid and reliable for implementing in Thai children with asthma.     

The clinical benefit of evaluating health-related quality-of-life in children with problematic severe asthma

Aim: To evaluate health‐related quality‐of‐life (HR‐QoL) and the asthma control test (ACT) in children with problematic severe asthma and those with controlled asthma and to identify whether clinical characteristics show correlations with these measurements. Methods: This multicentre cross‐sectional study included 93 children in total, 54 with problematic severe asthma and 39 age‐matched with controlled asthma. Subjects completed the Paediatric Asthma Quality‐of‐Life Questionnaire as well as a standardized health questionnaire and the ACT. Objective measurements of exhaled nitric oxide, specific sensitization, pulmonary function and bronchial hyper‐responsiveness to methacholine were also taken. Results: HR‐QoL was reduced in children with problematic severe asthma (5.4 vs. 6.7, p < 0.001), particularly for girls (5.1 vs. 5.6 for boys, p = 0.02), and their ACT scores were also lower (17 vs. 23, p < 0.001) compared with those of subjects with controlled asthma. A HR‐QoL score <6.2 discriminated problematic severe asthma from controlled asthma with 85% sensitivity and 97% specificity, as did the ACT score <20 (79% sensitivity and 94% specificity). Objective measures and other clinical characteristics were weakly associated with HR‐QoL or ACT score. Conclusion: Subjective measurements of HR‐QoL and asthma control are both equally useful in differentiating children with problematic severe asthma from those with controlled asthma.     

Comparison of the efficacy and safety of ciclesonide 160 μg once daily vs. budesonide 400 μg once daily in children with asthma

Ciclesonide is an onsite-activated inhaled corticosteroid (ICS) for the treatment of asthma. This study compared the efficacy, safety and effect on quality of life (QOL) of ciclesonide 160 microg (ex-actuator; nominal dose 200 microg) vs. budesonide 400 microg (nominal dose) in children with asthma. Six hundred and twenty-one children (aged 6-11 yr) with asthma were randomized to receive ciclesonide 160 microg (ex-actuator) once daily (via hydrofluoroalkane metered-dose inhaler and AeroChamber Plus spacer) or budesonide 400 microg once daily (via Turbohaler) both given in the evening for 12 wk. The primary efficacy end-point was change in forced expiratory volume in 1 s (FEV1). Additional measurements included change in daily peak expiratory flow (PEF), change in asthma symptom score sum, change in use of rescue medication, paediatric and caregiver asthma QOL questionnaire [PAQLQ(S) and PACQLQ, respectively] scores, change in body height assessed by stadiometry, change in 24-h urinary cortisol adjusted for creatinine and adverse events. Both ciclesonide and budesonide increased FEV1, morning PEF and PAQLQ(S) and PACQLQ scores, and improved asthma symptom score sums and the need for rescue medication after 12 wk vs. baseline. The non-inferiority of ciclesonide vs. budesonide was demonstrated for the change in FEV1 (95% confidence interval: -75, 10 ml, p = 0.0009, one-sided non-inferiority, per-protocol). In addition, ciclesonide and budesonide showed similar efficacy in improving asthma symptoms, morning PEF, use of rescue medication and QOL. Ciclesonide was superior to budesonide with regard to increases in body height (p = 0.003, two-sided). The effect on the hypothalamic-pituitary-adrenal axis was significantly different in favor of ciclesonide treatment (p < 0.001, one-sided). Both ciclesonide and budesonide were well tolerated. Ciclesonide 160 microg once daily and budesonide 400 microg once daily were effective in children with asthma. In addition, in children treated with ciclesonide there was significantly less reduction in body height and suppression of 24-h urinary cortisol excretion compared with children treated with budesonide after 12 wk.     

Assessment of quality of life in asthmatic Turkish children

Our aim was to assess impairment in quality of life (QOL) in asthmatic children and to determine the influencing factors. The study group consisted of 305 outpatients with asthma, aged 7-17 years, who were undergoing regular checkups in our outpatient clinic. QOL was assessed using the Pediatric Asthma QOL Questionnaire (PAQLQ). Asthma severity, presence of allergic rhinitis, and steroid usage were strongly and negatively associated with the overall PAQLQ score (p = 0.038) in multivariate regression models. Sex, IgE levels, positive skin tests and smoking status demonstrated no statistically significant effects on the overall or three individual domain PAQLQ scores (p = 0.307, 0.137, 0.470, 0.353, respectively). Lung function measures were strongly correlated with each other (Spearman correlation of 0.77), but were not associated with QOL (p = 0.441). Fifty-one percent of the patients reported that asthma affected their lives significantly. This study captured the baseline QOL information about the pediatric asthmatic population and factors influencing QOL and will facilitate longitudinal monitoring.     

A cluster randomised intervention trial of asthma clubs to improve quality of life in primary school children: the School Care and Asthma Management Project (SCAMP).

AIM: To evaluate the effectiveness of a programme of asthma clubs in improving quality of life in primary school children with asthma. METHODS: A cluster randomised intervention trial was undertaken in 22 primary schools within the urban area of south and east Belfast, Northern Ireland. Schools were randomised in pairs to immediate or delayed groups. The study subjects comprised 173 children aged 7-11 years whose parents had notified the school of their asthma diagnosis. Children attended school based weekly clubs over an 8 week period. The main outcome measures were the interview administered Paediatric Quality of Life Questionnaire scores, ranging from 1 (worst) to 7 (best), spirometry, and inhaler technique. RESULTS: Over 15 weeks, small but non-significant improvements in the overall quality of life score (mean 0.20; 95% confidence interval (CI) -0.20 to 0.61) and in each of its three components, activity limitation (0.20; -0.43 to 0.84), symptoms (0.23; -0.23 to 0.70), and emotional function (0.17; -0.18 to 0.52), were observed in the immediate compared with the delayed group. Inhaler technique at week 16 was markedly better in the immediate group, with 56% having correct technique compared with 15% in the delayed group. No significant effect of the intervention on spirometry results could be demonstrated. CONCLUSION: This primary school based asthma education programme resulted in sustained improvements in inhaler technique, but changes in quality of life scores were not significant.     

Asthma control in the quality of life levels of asthmatic patients’ caregivers: a systematic review with meta-analysis and meta-regression

ObjectiveTo perform a systematic review with meta-analysis and meta-regression to correlate the total scores of asthma control with the increase in the total scores of health-related quality of life levels of parents of asthmatic children.SourcesThe search was carried out in the following databases: PubMed (MEDLINE); Embase and ScienceDirect (Elsevier); SciELO and LILACs (Bireme) in June 2017. The included studies assessed asthma control through the Asthma Control Questionnaire (ACQ), Asthma Control Test (C-ACT/ACT), and Global Initiative for Asthma (GINA) questionnaires, whereas the Pediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ) was applied to assess the HRQoL of parents and family members.Summary of the findings294 articles were evaluated in the selected databases, of which (n = 38) were excluded for duplicity; (n = 239) after the reading of the titles and abstracts and (n = 5) after reading the studies in full, totaling 12 studies eligible for the meta-analysis. Of the 12 eligible articles, 11 (92%) were published in the last five years, and evaluated children and adolescents aged 1–20 years, totaling 2804 samples. In the evaluation of the correlation between the disease control scores by ACQ and C-ACT/ACT, the results were satisfactory for both ACQ analyses [R²: ?0.88; p < 0.001], and for C-ACT/ACT [R²: 0.82; p < 0.001].ConclusionsThe results show that asthma control levels can influence the total HRQoL scores of parents or relatives of children and adolescents with asthma.     

Family asthma management routines: connections to medical adherence and quality of life

OBJECTIVES: To develop a reliable measure of asthma management routines and examine its association with health care utilization, medical adherence, and quality of life. STUDY DESIGN: Families (n = 153) with a child with asthma, drawn from two sites, participated in the study. Parents completed the Asthma Routines Questionnaire, Adherence to Clinical Trials interview, Functional Severity of Asthma Questionnaire, and Caregiver Quality of Life. Children completed the Pediatric Quality of Life. Electronic monitoring of medication use over a period of 12 months was available for children at one study site. RESULTS: A principal component factor analysis revealed two dimensions to the Asthma Routines Questionnaire: Medication Routines and Routine Burden. Medication Routines were related to medical adherence and to health care utilization. Routine Burden was related to caregiver and child quality of life. CONCLUSIONS: The Asthma Routine Questionnaire holds promise as a reliable assessment of family practices related to medication use. The emotional burden of daily care can be distinguished from medication use, which is more closely linked to adherence issues. Targeted questions during regular care may reveal family routine practices amenable to intervention.     

Use of the Italian version of the Pediatric Asthma Quality of Life Questionnaire in the daily practice: results of a prospective study

Background  

Asthma is a serious global health problem and its prevalence is increasing, especially among children. It represents a significant social and economic burden, and it can severely affect the health-related quality of life (HRQL) of patients. Among the numerous questionnaires aiming at evaluating asthma HRQL in children, the Pediatric Asthma Quality of Life Questionnaire (PAQLQ) has proved to have good measurement properties.     

Critical comparison of some questionnaires for the evaluation of the quality of life in children affected by asthma

AIM: The aim of this study was to critically compare 9 different questionnaires for the evaluation of the Quality of Life in children affected by asthma. METHODS: The questionnaires were analyzed by considering their psychometric characteristics (reliability, validity, responsiveness, least clinically relevant difference), together with other practical and technical aspects (number of items, number and kind of domains, scaling of items, scoring, time to complete). Data were obtained from the scientific literature. RESULTS: Only 1 of the 9 analyzed questionnaires (Pediatric Asthma Quality of Life Questionnaire, PAQLQ) appears fully validated from a psychometrical standpoint. Moreover, it is the only one to have a validate translation into the Italian language. CONCLUSIONS: The authors suggest the use of the PAQLQ as tool of choice in the evaluation of the Quality of Life in children affected by asthma.     

Emotional quality-of-life and outcomes in adolescents with asthma

OBJECTIVE: Examine the association between emotional quality-of-life (QOL) and asthma morbidity in adolescents with asthma. STUDY DESIGN: Cross-sectional survey of 185 adolescents with asthma 11 to 17 years of age cared for in three managed care organizations (MCOs) in the United States. The asthma-specific Pediatric Asthma Quality of Life Questionnaire (PAQLQ) and a short version of the generic Child Health and Illness Profile-Adolescent Edition (CHIP-AE) were used to assess emotional QOL. Asthma morbidity measures were: asthma control, emergency department (ED) visits, hospitalizations, doctor visits for worsening asthma, and missed school because of asthma. RESULTS: Of the adolescents surveyed, 45% reported feeling depressed, 41% had ED visits, and 30% missed >or=1 day of school because of asthma. Poorer asthma-specific emotional QOL was associated with poorer control of asthma symptoms ( P < .0001), missed school (OR 7.1, P < .05), and doctor visits for worsened asthma (OR = 7.0, P < .05). CONCLUSIONS: Emotional symptoms related to asthma are common in adolescents with persistent asthma and asthma-specific QOL is related to increased asthma morbidity, healthcare use, and school absenteeism. Adolescents with high morbidity from asthma exhibit poorer QOL. Therefore, the evaluation of asthma-specific emotional QOL should be included in the assessment of adolescents with asthma.     

Specific instruments to assess quality of life in children and adolescents with asthma

ObjectiveTo identify and describe specific instruments to assess health-related quality of life (HRQoL) in children and adolescents with asthma.Data sourceSearches were performed in the PubMed, Ovid, and LILACS databases using different combinations of key words (MeSH terms), selecting original articles on the development of specific HRQoL questionnaires, published in English, Portuguese, or Spanish, between 1990 and 2012.Data synthesisA total of 15 instruments that met the inclusion criteria were identified. Most studies assessed reliability through internal consistency, reproducibility, and/or sensitivity to changes. Validity was assessed by comparison with healthy controls (discordant validity) or factorial analysis.ConclusionsOf the 15 instruments, three are the most frequently used: Pediatric Asthma Quality of Life Questionnaire (PAQLQ), Pediatric Quality of Life Inventory 4.0 (PedsQL-Asthma), and Disability Kids (DISABKIDS). In general, these three tools have adequate psychometric characteristics and are practical to implement, but only PAQLQ has been culturally adapted to Brazil.

An Examination of Factors Affecting Quality of Life for Children With Asthma and Their Caregivers in Southeastern Georgia

IntroductionDespite effective treatments and interventions, asthma continues to affect children's health-related quality of life (QOL). This study explored factors affecting QOL of children with asthma and their caregivers.MethodsA mixed-model design was used. Children (7–17 years) completed the Paediatric Asthma Quality of Life Questionnaire, and parents/caregivers completed the Paediatric Asthma Caregiver's Quality of Life Questionnaire. These surveys focused on activity limitations, emotional function, and child symptoms.ResultsThe sample included 104 children and 104 caregivers. Analysis showed emergency department (ED) visits as a significant predictor of QOL for children in the domains of Physical Activity, Emotional, and Symptoms. Increased ED visits and reliever medication use predicted lower emotional QOL and physical QOL for parents, whereas increased use of controller medications predicated improved physical QOL.DiscussionFactors contributing to QOL, along with characteristics of those with the lowest QOL indicators, have been determined. Identification of interventions to reduce ED visits warrants further investigation.

Efficacy and safety of montelukast as monotherapy in children with mild persistent asthma

OBJECTIVE: To study the efficacy and tolerability of montelukast as monotherapy in the treatment of mild persistent bronchial asthma. DESIGN: Open, non-comparative, prospective, 12-month study. SETTING: Asthma clinic in urban multi-speciality trust hospital. METHODS: Children (age 3-11 yrs) with mild persistent asthma, not on any prophylactic drugs were enrolled consecutively (from January to December 2003) and started on 4 mg (2-4 yrs) or 5mg (<4 yrs) montelukast for a period of 12 weeks. Efficacy was assessed by improvements in clinical score, peak expiratory flow rates (PEFR), spirometry measurements and reduction in reliever drug requirement after 4 and 12 weeks of therapy. Side effects were also judged after 12 weeks of therapy. RESULTS: 50 children (mean age 5.41 +/-2.11 years) completed the study. There was association with positive family history (92%), allergic rhinitis (64%), exercise induced asthma (40%), cough variant asthma (24%), seasonal asthma (80%) and high IgE (12%) levels. Clinical scores, viz, activity, wheeze and cough, improved effectively from (1.64 +/-0.5253) at baseline to (0.7 +/-0.7071) and (1.72 +/-0.701) to (0.92 +/-0.6952) and (1.5 +/-0.6145) to (0.88 +/-0.8241) respectively after 12 weeks of therapy. Significant clinical improvement (p >0.001) was also noted after 4 weeks of therapy. Peak expiratory flow rates (done in 19 cases) documented improvement from (120.21 +/-12.23) at baseline to (135.41 +/-23.34) after 12 weeks. FEV1 / FVC (done in 11 cases) improved from (71.44 +/-1.35%) to (87.10 +/-8.34%) after 12 weeks. Mean improvement in all the parameters demonstrated P value less than >.001. A total of 19 of 50 cases showed mild side-effects as anorexia (16%), elevated liver function tests (18%) and headache (10%). CONCLUSION: The clinical outcome showed significant improvement (p < 0.01) after 4 and 12 weeks.     

Quality of Life in Children with Asthma in Rio de Janeiro, Brazil

Objectives

To evaluate the impact of asthma on activity limitation, symptoms and emotional function in the health-related quality of life (HRQL) of asthmatic children.

Methods

A cross-sectional study involving 59 children of 7 to 12 y of age. A standardized version of the Pediatric Asthma Quality of Life Questionnaire was used to evaluate HRQL and the current criteria for socioeconomic stratification in Brazil were used to assess socioeconomic status. Independent variables evaluated included clinical and sociodemographic characteristics. The association between mean HRQL scores and the independent variables was evaluated using the Mann-Whitney, Kruskal-Wallis and Dunn tests. Statistical significance was defined as a p-value?<?0.05.

Results

Thirty-two families (56.1 %) had a total household income of more than two minimum wages, while 37 families (62.7 %) were considered lower middle class. Mean overall HRQL score was 4.8?±?1.3 (out of a maximum score of 7), suggesting reasonable HRQL. There was a weak association between independent variables and mean overall HRQL scores and the mean scores in the emotional function domain. Higher socioeconomic status was related to higher scores for the symptoms domain (p?=?0.041). Furthermore, children exposed to indoor mould reported greater impairment in the symptoms domain(p?=?0.022). The severity of asthma was associated with the activity limitation domain (p?=?0.025).

Conclusions

These results showed a reasonable mean HRQL score and an association between the severity of asthma and the activity limitation domain.
