Most children with asthma have poor inhaler technique, with detrimental morbidity effects. Guidelines recommend clinicians provide inhaler education at every opportunity, yet resources are limited. A low-cost, technology-based intervention-Virtual Teach-to-Goal (V-TTG)-was developed to deliver tailored inhaler technique education with high fidelity.
To evaluate whether V-TTG leads to less inhaler misuse among children with asthma who are hospitalized vs brief intervention (BI, reading steps aloud).
A single-center randomized controlled trial of V-TTG vs BI was conducted with 5-to-10-year-old children with asthma hospitalized between January 2019 and February 2020. Inhaler technique was assessed pre- and post-education using 12-step validated checklists (misuse: < 10 steps correct).
Among 70 children enrolled, mean age was 7.8 years (SD = 1.6). Most (86%) were Black. Most had an emergency department visit (94%) or hospitalization (90%) in the previous year. At baseline, nearly all children misused inhalers (96%). The proportion of children with inhaler misuse decreased significantly in V-TTG (100%→74%, P = .002) and BI (92%→69%, P = .04) groups, with no difference between groups at both time points (P = .2 and .9). On average, children performed 1.5 more steps correctly (SD = 2.0), with greater improvement with V-TTG (mean [SD] = 1.7 [1.6]) vs BI (mean [SD] = 1.4 [2.3]), though not significant (P = .6). Concerning pre and post technique, older children were significantly more likely than younger children to show more correct steps (mean change = 1.9 vs 1.1, P = .002).
A technology-based intervention for tailored inhaler education led to improved technique among children, similarly to reading steps aloud. Older children saw greater benefits. Future studies should evaluate the V-TTG intervention across diverse populations and disease severities to identify the greatest impact.

大多数哮喘儿童的吸入器技术较差,这会导致不良的发病率。指南建议临床医生在任何机会都提供吸入器教育,但资源有限。一种低成本、基于技术的干预措施-Virtual Teach-to-Goal(V-TTG)-被开发出来,以提供高保真度的定制吸入器技术教育。
评估 V-TTG 是否比简短干预(BI,大声朗读步骤)导致住院哮喘儿童的吸入器使用不当更少。
对 2019 年 1 月至 2020 年 2 月期间住院的 5 至 10 岁哮喘儿童进行了 V-TTG 与 BI 的单中心随机对照试验。使用 12 步验证检查表评估吸入器技术在教育前后(错误:<10 步正确)。
在 70 名入组的儿童中,平均年龄为 7.8 岁(SD=1.6)。大多数(86%)为黑人。大多数(94%)儿童在过去一年中有过急诊就诊或住院(90%)。在基线时,几乎所有的儿童都错误地使用了吸入器(96%)。在 V-TTG(100%→74%,P=.002)和 BI(92%→69%,P=.04)组中,吸入器使用不当的儿童比例均显著下降,两组在两个时间点均无差异(P=。2 和.9)。平均而言,儿童正确完成的步骤增加了 1.5 个(SD=2.0),V-TTG(平均[SD] 1.7 [1.6])的改善大于 BI(平均[SD] 1.4 [2.3]),但无统计学意义(P=。6)。关于吸入器技术的前后变化,年龄较大的儿童比年龄较小的儿童更有可能显示出更多的正确步骤(平均变化 1.9 比 1.1,P=.002)。
针对定制吸入器教育的基于技术的干预措施可改善儿童的技术,与大声朗读步骤相似。年龄较大的儿童受益更大。未来的研究应评估 V-TTG 干预措施在不同人群和疾病严重程度中的效果,以确定最大的影响。
