| Popis: | This equivalence and noninferiority randomized clinical trial assesses whether a virtual teach-to-goal intervention is noninferior to an in-person teach-to-goal intervention for improving inhaler technique among adult patients hospitalized with asthma or chronic obstructive pulmonary disease. Key Points Question Among patients hospitalized with asthma or chronic obstructive pulmonary disease (COPD), is a patient-driven virtual educational intervention as effective as the criterion standard in-person teach-to-goal intervention for improving medication use skills? Findings In this equivalence and noninferiority trial of 118 adult inpatients with asthma or COPD, the increase in the percentage of persons with improved medication skills was similar in the virtual teach-to-goal group (67%) and the in-person teach-to-goal group (66%), although the postintervention group comparison did not meet the a priori noninferiority significance level. Meaning The findings suggest that, for adults hospitalized with asthma or COPD, the novel virtual intervention provides guideline-recommended care nearly as well as the time-intensive in-person strategy. Importance Many patients who are hospitalized cannot use inhalers correctly, yet education for their use is often not provided. To address the need for an effective intervention feasible for wide-scale implementation, a virtual teach-to-goal intervention was developed to provide tailored patient-directed education using adaptive learning technology. Objective To assess whether the virtual teach-to-goal intervention is noninferior to an in-person teach-to-goal intervention for improving inhaler technique. Design, Setting, and Participants An equivalence and noninferiority randomized clinical trial took place from January 13, 2016, through September 20, 2017, with analyses conducted between October 25, 2017, and September 23, 2019. Adult inpatients with asthma or chronic obstructive pulmonary disease (COPD) admitted to general inpatient wards were eligible. Enrolled participants were randomized to virtual (n = 61) or in-person (n = 60) educational interventions. Investigators and research assistants were masked to interventions. Initial enrollment, study assessments, and delivery of the educational intervention occurred in the hospital; participants returned at 30 days for a follow-up research visit. Interventions Virtual education was a module delivered via handheld tablet with self-assessment questions before demonstration, narrated video demonstration of the correct technique, and self-assessment questions after demonstration; up to 3 rounds were repeated as needed. In-person education participants received iterative rounds of inhaler technique assessment and education by trained staff. Main Outcomes and Measures Noninferiority testing of whether virtual vs in-person education achieved an equal percentage with correct inhaler technique after education (>9 of 12 steps correct) against an a priori noninferiority limit of –10%; logistic regression models were used to adjust for differences in baseline technique and health literacy. Results Among 118 participants (59 in each group), most were black (114 [97%]) and female (76 [64%]), with a mean (SD) age of 54.5 (13.0) years. Correct technique increased similarly before vs after education in virtual (67%; range, 2%-69%) and in-person (66%; range, 17% to 83%) groups, although the difference after intervention exceeded the noninferiority limit (–14%; 95% CI lower bound, –26%). When adjusting for baseline inhaler technique, the difference was equivalent to the noninferiority limit (–10%; 95% CI lower bound, –22%). Conclusions and Relevance The findings suggest that patient-directed virtual education similarly improved the percentage of participants with correct technique compared with in-person education. Future work should confirm whether virtual teach-to-goal education is noninferior to in-person education and whether it is associated with long-term skills retention, medication adherence, and improved health outcomes.
