To investigate the effects of inhaler device technique education on improving inhaler technique in older people with asthma.
In a randomised controlled trial, device technique education was provided to a sample of 123 adults aged >55 years who had a doctor diagnosis of asthma. The active education group received one-on-one technique coaching, including observation, verbal instruction and physical demonstration at baseline. The passive group received a device-specific instruction pamphlet only. Inhaler technique, including the critical steps for each device type, was assessed and scored according to Australian National Asthma Council (NAC) guidelines. Device technique was scored objectively at baseline and again at 3 and 12 months post education.
The majority of participants demonstrated poor technique at baseline. Only 11 (21%) of the active intervention group and 7 (16%) of the passive group demonstrated 100% correct technique. By 3 months 26 (48%) of the active group achieved adequate technique. Improvement in technique was observed in the active group at 3 months (P<0.001) and remained significant at 12 months (P<0.001). No statistically significant improvement was observed in the passive group.
The provision of active device technique education improves device technique in older adults. Passive education alone fails to achieve any improvement in device technique.
调查吸入器装置技术教育对改善老年哮喘患者吸入器技术的影响。
在一项随机对照试验中，对 123 名年龄>55 岁且经医生诊断为哮喘的成年人样本进行了装置技术教育。主动教育组在基线时接受了一对一的技术辅导，包括观察、口头指导和物理示范。被动组仅接受了特定设备的说明书。根据澳大利亚国家哮喘委员会（NAC）指南评估和评分吸入器技术，包括每种设备类型的关键步骤。在基线和教育后 3 个月和 12 个月时客观地对设备技术进行评分。
大多数参与者在基线时表现出较差的技术。仅 11 名（21%）主动干预组和 7 名（16%）被动组表现出 100%正确的技术。到 3 个月时，主动组有 26 名（48%）达到了足够的技术水平。在 3 个月时（P<0.001）和 12 个月时（P<0.001），主动组的技术得到了改善，观察到显著的改善。被动组未观察到统计学上显著的改善。
主动提供设备技术教育可改善老年人的设备技术。单独的被动教育未能实现设备技术的任何改善。
