Digital Adherence Technologies
Video Supported Treatment (VST)
Video Supported Treatment (VST) allows individuals to video record their medication intake, which the health care provider can watch at a later stage.
DAT users are guided through a secured mobile application to record videos of themselves ingesting their daily medication. This is then uploaded to a secure remote server that can be accessed by the health care provider to review the doses taken.
If a video is not sent when expected, or if the medication intake is unclear in the video, the healthcare worker can contact the DAT user to determine the problem and provide support, to ensure future medication adherence.
Considerations
To determine whether video supported treatment (VST) is suitable for target population and context, certain elements need to be considered.
Each consideration is scored according to a favourability scale as low, medium or high. Low indicating less favourability, and high indicating increased favourability compared to the other digital adherence technologies.
These considerations are based on the ASCENT Project Technical Brief, summarizing the implementation experiences with three technologies in 5 countries.
EASE FOR PATIENT TO USE TECHNOLOGY: LOW
- Patient needs to record medication intake by video for the entire treatment duration. This is expected to take 3 – 5 minutes each day.
- Patient may feel uncomfortable about privacy associated with video recording themselves.
EASE FOR HEALTHCARE WORKER TO USE TECHNOLOGY: LOW
- Provider needs to review and verify each patient medication intake video. This is expected to take 4 – 6 minutes per patient per day. However, this can take longer if there is a video recording error that needs to be followed up on.
ACCESSIBILITY: LOW
- Patient needs daily access to a smart phone.
- Patient needs daily access to Wi-Fi or mobile data network.
- Health care provider requires technology to review videos – a smartphone / tablet or computer as well as data or Wi-Fi.
- Country legislation on data and privacy may restrict sending, storing, and sharing videos.
EASE OF IMPLEMENTATION: HIGH
- No specialized in-country infrastructure required.
- Video recording adherence app can be easily downloaded and installed.
SUITABILITY FOR USE WITH DIFFERENT DRUG TYPES: HIGH
- Suitable across all medication types.
