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.
METHODSAfter
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.
RESULTSMean
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).
CONCLUSIONSThere 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 differences. Even
under ideal conditions, home spirometry provides an incomplete (and
therefore potentially biased) picture of long term changes in pulmonary function.
