Cross-sectional study assessing the performance of the Arabic translated childhood asthma control test

Validity of the Childhood Asthma Control Test in diverse populations: A systematic review

PURPOSE

We examined the validity of the Childhood Asthma Control Test (C-ACT) and identified recommended thresholds for uncontrolled asthma in children from varying backgrounds.

METHODS

A systematic literature review was performed utilizing PubMed, Ovid Medline, SCOPUS, CINAHL, and conference proceedings. Studies were included if they enrolled children, had a primary outcome of asthma control, examined test validity or psychometrics, and utilized the C-ACT. Along with study design and demographic data, we extracted all outcomes and comparisons used to validate the C-ACT. We evaluated risk of bias using the COSMIN Risk of Bias tool. Our protocol was registered with PROSPERO (CRD42020211119).

RESULTS

Of 4924 records screened, 28 studies were included. Studies were conducted internationally and published between 2007 and 2018. Average number of enrolled participants was 193 (SD = 155, range = 22-671). Ten studies calculated Cronbach's α (mean [SD] = 0.78(0.05), range = 0.677-0.83). Thirteen studies recommended cut-offs for uncontrolled asthma (≤18-≤24). Nine studies found significant agreement or correlation between C-ACT and Global Initiative for Asthma guidelines/physician assessment of asthma control (correlation coefficients range = 0.219-0.65). Correlation coefficients between C-ACT and spirometry were <0.6 in five of six studies that included spirometry. Kappa values for C-ACT and various spirometry measurements ranged 0.00-0.34.

CONCLUSIONS

The C-ACT showed good internal consistency and mixed levels of agreement and correlation with various clinical asthma measures. Recommended cut-offs for asthma control varied and had no consistent relationship with nationality, race, ethnicity, or language. Few studies examined cross-cultural validity and multiple populations remain under-studied.

Asthma education and its impact on pediatric asthma severity: a prospective cohort study

OBJECTIVE

Asthma education has been shown to improve asthma control. Our goal was to evaluate the efficacy of asthma education on the frequency of utilization of health-care services, lung function results, degree of asthma severity, and quality of life (QOL) level in children with asthma.

METHODS

A single-arm prospective interventional trial was conducted in a tertiary facility. Thirty children with asthma and their parents were recruited for the research. Following an assessment of the participants' and caregivers' knowledge about asthma using an asthma knowledge questionnaire, degree of asthma control using asthma control test, inhaler technique using standardized inhaler technique checklists, and QOL using pediatric asthma QOL questionnaires, they participated in a three-month education program in the form of monthly live interactive sessions followed by weekly phone interviews. Measures taken before and after the intervention were compared.

RESULTS

The educational intervention improved asthma control dramatically including daytime asthma symptoms, night awakenings, and frequency of use of short-acting beta2- adrenergic receptor agonists. Furthermore, the number of emergency department visits and hospitalizations fell considerably after the intervention (p < 0.001 for all). Asthma education was also linked to better inhalation technique and lung function (p < 0.001). Furthermore, all quality-of-life measures increased (p < 0.001 for all).

CONCLUSIONS

Implementing an asthma education program that included both children with asthma and their parents improved asthma control levels, lung function measures, and overall quality of life. Furthermore, it increased asthma awareness, decreased the use of health-care resources, and reduced asthma severity, resulting in better asthma management.

Parental attitude and knowledge towards asthma care measures for their children in Saudi Arabia

BACKGROUND

Appropriate asthma management in children reduces emergency department visits, hospitalization, and improves the quality of life. We aim to assess the level of children asthma control and its association with parental knowledge.

METHODS

A prospective study conducted to measure childhood asthma control with a validated childhood asthma control test (C-ACT), and to assess asthma knowledge among the parents of children aged 4-11 years and their parents upon asthma clinic visits. C-ACT score ≤ 19 is considered as uncontrolled child asthma.

RESULTS

We have invited 238 parents to participate in the study; 177 (74.4%) completed the survey. The mean age of the parents and their children were 38.8 ± 7.6 and 7.8 ± 2.7 years, respectively; 28.2% of parents were smokers, and 46.3% of them were college graduated. Nearly 61.6% of the parents and children scored ≤ 19 on C-ACT; 54.2% and 37.9% of parents knew how inhaled salbutamol and corticosteroids work, respectively. A quarter of the parents received an asthma action plan. Multinomial logistic regression analysis showed that parents who did not know their children's medications name (OR, 6.1; 95% CI, 2.15-17.29), and when to use inhaled corticosteroid (OR, 2.1; 95% CI, 1.32-3.45) were independent factors predicting uncontrolled asthma in children with score ≤ 19.

CONCLUSIONS

The study indicated that there is an association between poor asthma control (scored ≤ 19 on C-ACT) and parental knowledge of asthma medications. The parents should be educated thoroughly on asthma care, including medications used to minimize asthma exacerbations in their children.
