Patient knowledge of correct inhaler technique is essential in the treatment of pulmonary disease. Computer delivery of educational content may augment existing teaching efforts.
To determine whether a computer-based tutorial on inhaler technique could improve patients' knowledge and ability to correctly demonstrate inhaler technique.
A total of 34 adults with pulmonary disease and experience using inhalers were randomized into the control or intervention groups. The intervention group viewed the tutorial, after which they demonstrated their inhaler technique and completed an Inhaler Technique Knowledge Test. Control group patients, who did not view the tutorial, were also evaluated on their demonstrated inhaler technique and technique knowledge. Additional information obtained included demographics, illness and treatment history, and patients' use of computers. Lastly, all patients who viewed the tutorial completed a brief questionnaire eliciting tutorial feedback. Control group patients were invited to view the tutorial after other data collection was complete. The 2 principal outcomes were the observed inhaler technique score and the inhaler technique knowledge test score. Comparisons between groups were conducted using Student's t-test and chi(2) test, with a p value less than 0.05 considered statistically significant.
Eighteen subjects were enrolled in the computer group; 16 were in the control group. The intervention group demonstrated significantly better inhaler technique, with a mean Observed Inhaler Technique Score of 88.3 +/- 12.3 compared with 67.4 +/- 19.2 for the control group (p = 0.001). The intervention group also scored significantly higher on the Inhaler Technique Knowledge Test, with a score of 80.9 +/- 17.0 versus 67.4 +/- 11.8 for the control group (p = 0.01). Overall, the program appeared acceptable to patients.
Patients in the tutorial group demonstrated better inhaler technique and scored higher on the Inhaler Technique Knowledge Test compared with those in a control group. This tutorial may be a useful educational tool to enhance patient education regarding inhaler technique.
患者对正确吸入器使用技术的了解对于肺部疾病的治疗至关重要。通过计算机提供教育内容可能会增强现有的教学效果。
确定一个基于计算机的吸入器技术教程是否能提高患者对吸入器技术的了解以及正确演示吸入器技术的能力。
共有34名患有肺部疾病且有使用吸入器经验的成年人被随机分为对照组或干预组。干预组观看教程，之后他们演示自己的吸入器使用技术并完成吸入器技术知识测试。未观看教程的对照组患者也接受吸入器使用技术演示和技术知识评估。获取的其他信息包括人口统计学数据、疾病和治疗史以及患者对计算机的使用情况。最后，所有观看教程的患者都完成了一份简短问卷以获取教程反馈。在其他数据收集完成后，邀请对照组患者观看教程。两个主要结果是观察到的吸入器技术得分和吸入器技术知识测试得分。使用学生t检验和卡方检验进行组间比较，p值小于0.05被认为具有统计学意义。
计算机组纳入18名受试者；对照组纳入16名。干预组的吸入器技术明显更好，观察到的吸入器技术平均得分为88.3±12.3，而对照组为67.4±19.2（p = 0.001）。干预组在吸入器技术知识测试中的得分也明显更高，得分为80.9±17.0，而对照组为67.4±11.8（p = 0.01）。总体而言，该项目似乎为患者所接受。
与对照组相比，教程组的患者在吸入器技术演示方面表现更好，在吸入器技术知识测试中的得分更高。这个教程可能是一个有用的教育工具，可加强关于吸入器技术的患者教育。
