方法：采用电子峰值流量仪对40例5~16岁哮喘儿童进行连续4周、每天2次的峰值流量测量，并记录在书面日记中。患者和家长并不知道该设备将峰值流量存储在微芯片上。按随机顺序，一半的患者只被告知该设备可以更准确地评估峰值流量，而另一半患者被告知准确记录峰值流量很重要，因为结果将用于指导治疗调整。结果：在整个研究人群中，平均(SD)实际遵从性(77.1(20.5)%)远低于平均报告遵从性(95.7(9.1)%)(95%CI为12.7%至24.4%)。正确高峰流量条目的百分比从56%下降到
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 tactual 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
