Development and Deployment of a Music Listening Intervention Mobile Application for a Two-Group Blinded Randomized Clinical Trial
Abstract
Music is one nonpharmacological intervention to reduce anxiety and stress for mechanically ventilated patients. Efficient delivery of a music listening intervention can be enhanced through digital tools such as a mobile application (app) loaded onto an electronic tablet device. The objective of this study is to describe the iterative development and deployment of a novel app (Soundese) to deliver, record, and retrieve data associated with a two-arm randomized, blinded clinical trial testing music listening intervention compared to control silence condition on delirium severity among critically ill intensive care unit (ICU) older adult patients receiving mechanical ventilatory support. The Soundese mobile app was developed to deliver either experimental music listening intervention or a silence control listening condition to a sample of older adults receiving mechanical ventilatory support in the ICU and retrieve all protocol data. The Soundese app was developed using the Swift software language and is compatible with all iOS devices. The Soundese app consists of two components: (1) a mobile app that delivers the assigned, blinded listening intervention from an iPad through headphones to each subject and automatically logs each listening session, its duration, the randomization arm, and uploads these data to a server, and (2) an analysis app that generates a spreadsheet with summarized data of the respective listening session, music details, and reports for further analyses. A Dropbox application programmer interface enabled the secure storage of files on a designated Dropbox account. After initial field testing and iterative development changes based on research staff feedback, the Soundese app delivers the assigned experimental listening condition or silence control condition when deployed remotely in the field. The app's mobile nature allows for immediate and automatic data capture, which is summarized for statistical analysis. There is no need for any manual recording of any intervention data by busy ICU staff, including listening time or music selections. The Soundese mobile app efficiently delivers the research protocol with fidelity and collects the necessary data for an ICU-based clinical trial. The app may be useful in other clinical trials testing music listening interventions in various settings or for deploying other audio-based interventions.
