Summary
A new mobile app, Soundese, efficiently delivers music interventions to reduce anxiety in mechanically ventilated patients. This digital tool automates data collection for clinical trials, simplifying research processes in intensive care units.
Area of Science:
- Digital health interventions
- Clinical trial methodology
- Critical care medicine
Background:
- Music is a non-pharmacological method to alleviate anxiety and stress in mechanically ventilated patients.
- Digital tools like mobile applications can enhance the delivery of music interventions.
- Critically ill older adults in the intensive care unit (ICU) receiving mechanical ventilatory support are a vulnerable population often experiencing anxiety and stress.
Purpose of the Study:
- To describe the development and deployment of the Soundese mobile application.
- To test the Soundese app's efficacy in delivering a music listening intervention versus a silence control in a randomized clinical trial.
- To assess the impact of the music intervention on delirium severity in older adult ICU patients.
Main Methods:
- The Soundese app was developed using Swift for iOS devices, featuring two components: a mobile app for intervention delivery and data logging, and an analysis app for data summarization.
- A secure Dropbox API was utilized for data storage.
- The app was iteratively developed and field-tested with research staff feedback before deployment in a two-arm randomized, blinded clinical trial.
Main Results:
- The Soundese app successfully delivered blinded listening interventions (music or silence) to participants remotely.
- The app automatically logged session duration, randomization arm, and other relevant data, eliminating manual recording by ICU staff.
- Data were securely stored and summarized for statistical analysis, demonstrating efficient protocol delivery and data capture.
Conclusions:
- The Soundese mobile app efficiently and reliably delivers music listening interventions and collects data for clinical trials in the ICU.
- The app's automated data capture streamlines research processes, reducing the burden on busy ICU staff.
- The Soundese app shows potential for use in other audio-based intervention trials across various clinical settings.

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...
