Abstract

BACKGROUND

A study was undertaken to investigate the compliance with and accuracy of peak flow diaries in childhood asthma.

METHODS

Forty asthmatic children (5-16 years) were asked to perform peak flow measurements twice daily for 4 weeks by means of an electronic peak flow meter and to record values in a written diary. Patients and parents were unaware that the device stored the peak flow values on a microchip. In random order, half of the patients were only told that the device allowed for more accurate assessment of peak flow while the other half were told that accurate recording of peak flow was important because the results would be used in guiding adjustments to treatment. Data in the written diary (reported data) were compared with those from the electronic diary (actual data).

RESULTS

In the entire study population the mean (SD) actual compliance (77.1 (20.5)%) was much lower than the mean reported compliance (95.7 (9.1)%) (95% CI for difference 12.7% to 24.4%) The percentage of correct peak flow entries decreased from 56% to <50% from the first to the last study week (p<0.04), mainly as a result of an increase in self-invented peak flow entries. Results were comparable for both groups. For incorrect peak flow entries the mean difference between written and electronically recorded entries ranged from -72 to 34 l/min per patient.

CONCLUSIONS

Peak flow diaries kept by asthmatic children are unreliable. Electronic peak flow meters should be used if peak flow monitoring is required in children with asthma.

摘要

背景

开展了一项研究,以调查儿童哮喘患者峰流速日记的依从性和准确性。

方法

40名哮喘儿童(5 - 16岁)被要求使用电子峰流速仪每天进行两次峰流速测量,持续4周,并在书面日记中记录测量值。患者及其家长并不知道该设备会将峰流速值存储在微芯片上。随机安排,一半患者仅被告知该设备能更准确地评估峰流速,而另一半患者被告知准确记录峰流速很重要,因为结果将用于指导治疗调整。将书面日记中的数据(报告数据)与电子日记中的数据(实际数据)进行比较。

结果

在整个研究人群中,实际平均依从性(标准差)为77.1(20.5)%,远低于报告的平均依从性(95.7(9.1)%)(差异的95%置信区间为12.7%至24.4%)。从研究的第一周到最后一周,正确的峰流速记录百分比从56%降至<50%(p<0.04),主要原因是自行编造的峰流速记录增加。两组结果具有可比性。对于错误的峰流速记录,每位患者书面记录与电子记录之间的平均差异在-72至34升/分钟之间。

结论

哮喘儿童所记的峰流速日记不可靠。如果哮喘儿童需要进行峰流速监测,应使用电子峰流速仪。
