“…4 Pelkonen et al reported 94% compliance with spirometric tests over a mean period of 24 days in newly diagnosed asthmatic children, but it is not reported whether this assessment was covert. 6 Our data (81.4% during the first 28 day period) are poorer than this. The children in our study were not newly diagnosed asthmatics, which perhaps reduced the novelty.…”

“…9 Other studies have reported excellent within session reproducibility 9 although, with a greater number of younger children, the proportion of successful manoeuvres may be lower than that observed in this study. 6 The DSS stores only the best manoeuvre and provides percentage variability in FVC + FEV 1 between the two best blows. This is the only measure of within session reproducibility.…”

“…With increased portability it is feasible to carry out spirometric monitoring in the home for clinical or research purposes. 6 Training for spirometric testing is important 7 as a potential reduction in spirometric values may occur with suboptimal eVort or inaccurate techniques. 8 9 This calls into question the validity of unsupervised measurements at home.…”

Background-Handheld electronic spirometers provide the opportunity for more comprehensive monitoring of lung function at home than has hitherto been available. The aim of this study was to assess the quality of spirometric data collected at home by 90 asthmatic schoolchildren aged 7-14 years. Methods-After training, children carried out twice daily recordings at home for four consecutive periods of 4 weeks using a data storage spirometer (Vitalograph), encouraged by 4-weekly visits from a research nurse. Compliance (proportion of blows recorded at correct time of day), technical quality (by machine criteria), and valid data recorded (the multiple of compliance and technical ability) were assessed. Results-Mean compliance declined from 81.4% to 70.4% (p<0.001) between the first and last month, although the technical quality of the manoeuvres (81.9% and 80.1%, respectively) did not change significantly (p=0.48). Conclusions-There was a steady reduction of valid data over the four periods (from 73.6% to 64.3%, 59.7%, and 57.6%) with wide individual diVerences. Even under ideal conditions, home spirometry provides an incomplete (and therefore potentially biased) picture of long term changes in pulmonary function.

“…There are a few paediatric studies with spirometry assessments performed at home [21,22]. WENSLEY and SILVERMAN [21] evaluated the ability of children aged 7-11 yrs to perform spirometry tests at home, without medical supervision [21].…”

“…There was a large variability in compliance, between 30 and 96%, with an average of 81% in the first month and 70% in the third month, indicating a significant reduction towards the end of the study. PELKONEN et al [22] demonstrated that children aged 5-10 yrs with a recent diagnosis of asthma were able to perform reproducible and valid spirometry tests at home. MORTIMER et al [23] demonstrated that portable spirometers could provide measurements that were highly comparable to those obtained from ''gold standard'' laboratory spirometers, and high-quality tracings could be achieved both at home and in the office setting.…”

Some children with severe asthma develop frequent exacerbations despite intensive treatment.We sought to assess the outcome (severe exacerbations and healthcare use, lung function, quality of life and maintenance treatment) of a strategy based on daily home spirometry with teletransmission to an expert medical centre and whether it differs from that of a conventional strategy.50 children with severe uncontrolled asthma were enrolled in a 12-month prospective study and were randomised into two groups: 1) treatment managed with daily home spirometry and medical feedback (HM) and 2) conventional treatment (CT).The children's mean age was 10.9 yrs (95% confidence interval 10.2-11.6). 44 children completed the study (21 in the HM group and 23 in the CT group). The median number of severe exacerbations per patient was 2.0 (interquartile range 1.0-4.0) in the HM group and 3.0 (1.0-4.0) in the CT group (p50.38 with adjustment for age). There were no significant differences between the two groups for unscheduled visits (HM 5.0 (3.0-7.0), CT 3.0 (2.0-7.0); p50.30), lung function (pre-b 2 -agonist forced expiratory volume in 1 s (FEV1) p50.13), Paediatric Asthma Quality of Life Questionnaire scores (p50.61) and median daily dose of inhaled corticosteroids (p50.86).A treatment strategy based on daily FEV1 monitoring with medical feedback did not reduce severe asthma exacerbations.
