Feasibility of a virtual multiple breath washout training program

Abstract

To maintain multiple breath washout (MBW) training capacity for clinical trials during the COVID-19 pandemic we developed a virtual alternative to in-person training. Here we report the feasibility of a fully virtual training program for the Exhalyzer^® D (EcoMedics AG, CH) MBW device.

Mixed media eLearning modules (Articulate) and a live webinar were developed and added to existing training components. Virtual training included 4 eLearning modules, a webinar and knowledge test on device calibration, MBW testing and test quality control. Participants were asked to complete a feedback survey (5-point Likert scale) at the end of training. Trainees then underwent the standard MBW qualification procedure.

To date, 111 MBW naïve participants from 57 sites across North America, Europe and Australia have completed virtual training. 50% (56/111) trainees completed the feedback survey, 93% (52/56) gave positive feedback regarding the design and ease of use of the virtual components. 93% (52/56) either agreed or strongly agreed that the modules enhanced their learning experience. However, only 59% (33/56) felt confident in conducting a MBW test after completing the training, which is lower than previously reported for in-person training (88/103; 85%). To date, 30 trainees have attempted qualification with 100% (30/30) success, which is comparable to past in-person training (54/57; 95%) (Au JWY., et al. Pediatr Pulmonol. 2018; 53(S2): 777).

Virtual MBW training is feasible and can effectively expand capacity; initial feedback indicates that a combination of virtual and hands-on learning may still be preferred. Enriching virtual resources allows us to reduce in-person requirements and increase flexibility of training. Funded by CFF
