The efficacy of delivering medicines by metered-dose inhaler (MDI) is well established, and the patient's technique with MDIs is related directly to achieving the desired clinical outcome. The present study was designed to assess and improve MDI technique by using a Vitalograph Aerosol Inhalation Monitor (VAIM) in an airways disease education programme. Baseline measurements were made immediately prior to educational intervention incorporating feedback from a VAIM unit. At 6 weeks' follow-up, MDI technique was found to have regressed to the sub-optimal measures recorded at baseline prior to educational intervention. However, patients reported a significant improvement in physical function between baseline and follow-up as measured by the Rand 36-Item Health Survey (SF-36), Version 1.0. The results reinforce the need for a longitudinal educational programme for patients prescribed medications delivered by MDI. The VAIM unit provided health educators and patients with both a visual and a quantitative assessment of patients' MDI technique, and was thus of positive value as part of the intervention process.
通过定量吸入器（MDI）给药的疗效已得到充分证实，患者使用MDI的技术与实现预期临床结果直接相关。本研究旨在通过在气道疾病教育项目中使用肺活量计气溶胶吸入监测仪（VAIM）来评估和改善MDI技术。在纳入VAIM设备反馈的教育干预之前，立即进行基线测量。在6周的随访中，发现MDI技术已退回到教育干预前基线时记录的次优水平。然而，根据兰德36项健康调查（SF - 36）1.0版测量，患者报告称基线与随访之间身体功能有显著改善。结果强化了为使用MDI给药的患者开展纵向教育项目的必要性。VAIM设备为健康教育者和患者提供了对患者MDI技术的视觉和定量评估，因此作为干预过程的一部分具有积极价值。
