To evaluate the impact of peak expiratory flow (PEF) monitoring using a smart peak flow (SPF) device on the quality of life (QoL) and satisfaction among children with asthma.
This 3-month prospective cohort study enrolled 71 children aged 7 to 17 years with physician-diagnosed asthma. Participants used the SPF device twice daily, with measurements recorded automatically. Quality of life was assessed using the Pediatric Asthma Quality of Life Questionnaire (PAQLQ), and asthma control was assessed using the Asthma Control Test (ACT) or Childhood Asthma Control Test (C-ACT). Adherence to PEF measurements and satisfaction with the device were evaluated.
Seventy-one children (mean age 11.4 years) completed the study. Adherence to twice-daily PEF measurements decreased significantly over three months (from 50.0% at 1 month to 39.9% at 3 months, < 0.001). Children with good adherence (38.0%) showed significant improvements in PAQLQ scores, while those with poor adherence (62.0%) did not. COVID-19 infection resulted in a significant decrease in %PEF rate and increased peak flow variability. Despite device-related issues, overall satisfaction was high (85.19% for good adherence users vs. 88.64% for poor adherence users, = 0.671).
Regular PEF monitoring improves QoL in children with asthma by enabling early detection of symptom changes and better management. However, maintaining adherence to regular PEF monitoring is challenging. Further research with control groups is needed to validate these findings.
评估使用智能峰流速（SPF）设备进行呼气峰流速（PEF）监测对哮喘儿童生活质量（QoL）和满意度的影响。
这项为期3个月的前瞻性队列研究纳入了71名年龄在7至17岁之间、经医生诊断为哮喘的儿童。参与者每天使用SPF设备两次，测量结果自动记录。使用儿童哮喘生活质量问卷（PAQLQ）评估生活质量，使用哮喘控制测试（ACT）或儿童哮喘控制测试（C-ACT）评估哮喘控制情况。评估对PEF测量的依从性以及对该设备的满意度。
71名儿童（平均年龄11.4岁）完成了研究。在三个月内，每天两次进行PEF测量的依从性显著下降（从第1个月的50.0%降至第3个月的39.9%，P<0.001）。依从性良好的儿童（38.0%）的PAQLQ评分有显著改善，而依从性差的儿童（62.0%）则没有。COVID-19感染导致PEF率百分比显著下降，峰流速变异性增加。尽管存在与设备相关的问题，但总体满意度较高（依从性良好的用户为85.19%，依从性差的用户为88.64%，P=0.671）。
定期进行PEF监测可通过早期发现症状变化和更好的管理来改善哮喘儿童的生活质量。然而，维持对定期PEF监测的依从性具有挑战性。需要进一步开展有对照组的研究来验证这些发现。
