Description of intervention(s) / exposure
This study is a two-arm controlled study aiming to investigate the feasibility of utilising a smartphone app (Oto) in tinnitus management as determined by trial acceptability, deliverability, and effectiveness. Oto is a smartphone app developed by Oto Health Ltd. which aims to help people manage their tinnitus and decrease their tinnitus severity. Oto is a novel multimodal app-delivered approach to tinnitus available for iOS and Android. It combines patient education, cognitive behavioural therapy (CBT), relaxation, mindfulness, and sound therapy in a customisable package. In particular, Oto provides a five-week tinnitus habituation program consisting of 60 recorded therapy sessions focusing on topics such as acceptance and commitment therapy (ACT), CBT, relaxation, mindfulness, and visualisation. Oto also offers a total of 116 therapy sessions (including those in the habituation program) that can be listened at the participants' own pace if they wish to explore beyond the habituation program. In general, each therapy session takes approximately 5-10 minutes to complete. Furthermore, Oto provides a sound library consisting of 78 kinds of sounds such as ocean, brown noise, and thunderstorm for masking tinnitus and facilitating sleep. Usage of Oto is self-paced and at the comfort of the participants' own home, though a suggested timescale for the habituation program is provided within the app. The self-paced and self-administered delivery method allows patients to avoid taking time off work, travel time to a hospital, and face-to-face contact with other people if necessary. As the nature of Oto is self-guided, all components of the app are optional based on the participants' needs and interests. However, Oto users were advised at the baseline to follow the suggested timeline for the habituation program as much as they could. No strategy was used to monitor adherence to using Oto, but participants' online written consent was sought to collect app usage data from Oto's end and these data will be de-identified and used for data analysis. Oto has received Medicines and Healthcare products Regulatory Agency (MRHA) certification as a Class 1 medical device in the UK. Participants in the Oto-user group were given cost free access to Oto for nine months (length of study period).
Participants were alternatively allocated to the two groups based on their order of recruitment, i.e., the first participant was allocated to the Oto user group, the second participant was allocated to the non-user group, and so on.
