“…Patients cannot reliably predict changes in their lung function based on the symptoms they experience 40 and physicians cannot accurately predict lung function from examinations of patients with asthma. 41 Changes in symptoms are a poor indicator of impending changes in lung function. 42 Symptom reporting may be affected by factors other than asthma itself.…”

“…[8][9][10] Conversely, physical signs may be inadequate for detecting bronchial obstruction with certainty, and considerable airway obstruction may be present despite a normal clinical examination. 11 Further, spirometry is not regularly performed by general practitioners treating patients with asthma, as reported by the Asthma Insights and Reality Europe study 12 : only 29% of subjects with asthma had undergone lung function testing in the past year, and Ͼ50% of subjects with asthma had never undergone spirometry. Thus, many patients with asthma are managed without going to specialized centers and without lung function assessment.…”

Perception of Asthma Symptoms as Assessed on the Visual Analog Scale in Subjects With Asthma: A Real-Life Study

BACKGROUND:The perception of symptoms is a cornerstone in asthma management, but studies concerning this aspect provide conflicting evidence. The visual analog scale has been proposed as a useful tool for assessing perception of respiratory symptoms. The present study investigated whether visual analog scale assessment of perception of asthma symptoms was correlated to lung function or clinical features. METHODS: This cross-sectional study enrolled 388 subjects with asthma (159 males; mean age 39.7 y). Perception of asthma symptoms was assessed by the visual analog scale; lung function was measured by spirometry. Asthma control was evaluated by the asthma control test. Anxiety and depression were evaluated on the Hospital Anxiety and Depression Scale questionnaire. RESULTS: Asthma was well controlled in 46.6% of subjects. Asthma symptoms in the prior month were reported by 59% of subjects; asthma signs were detected in 7.2%. The visual analog scale score was moderately correlated to FEV 1 (r ‫؍‬ 0.43). Subjects with bronchial obstruction had lower visual analog scale values than those without (P < .001). A visual analog scale score of 6 was a reliable cutoff point to discriminate subjects with bronchial obstruction (area under the curve ‫؍‬ 0.71 at receiver operating characteristic curve; odds ratio [OR] ‫؍‬ 7.58). Reported asthma symptoms (OR ‫؍‬ 4.83), asthma signs (OR ‫؍‬ 8.36), and anxiety (OR ‫؍‬ 1.14) were predictive of a visual analog scale score of <6. CONCLUSIONS: This real-life study found that assessment of asthma symptoms by the visual analog scale might be a reliable tool in managing patients with asthma.

“…Most studies of asthma perception have been conducted on adult patients (1,3,8,9) and only a few have been performed on children in natural environments (2,10,11). Factors that might influence the perception of asthma symptoms such as gender, age, sex, asthma severity and use of medications have not been fully addressed in children.…”

Individual ability to perceive airway obstruction varies substantially. The factors influencing the perception of asthma are probably numerous and not well established in children. The present study was designed to examine the influence of asthma severity, use of preventive medication, age and gender on the association between respiratory symptoms (RS) and peak expiratory flow (PEF) rates in asthmatic children. We followed 92 asthmatic children, aged 6 to 16 years, for five months. Symptom scores were recorded daily and PEF was measured twice a day. The correlations among variables at the withinperson level over time were analyzed for each child and for the pooled data by multivariate analysis. After pooling the data, there was a significant (P<0.05) correlation between each symptom and PEF; 60% of the children were accurate perceivers (defined by a statistically significant correlation between symptoms and PEF across time) for diurnal symptoms and 37% for nocturnal symptoms. The accuracy of perception was independent of asthma severity, age, gender or the use of preventive medication. Symptom perception is inaccurate in a substantial number of asthmatic children, independently of clinical severity, age, gender or use of preventive medication. It is not clear why some asthmatic patients are capable of accurately perceiving the severity of airway obstruction while others are not.
