Web-Based Communication
Web-based communication was achieved via a combination of an instant messaging app (WeChat) used by the patients and the Trusted Doctor app used by the case managers. The patients can initiate conversations or receive messages via the WeChat platform connected to the Trusted Doctor app. To avoid overburdening case managers, we set a limit that up to 5 messages could be initiated in 3 days by patients as default. Case managers were authorized to adjust the limit after the primary evaluation of the patient’s situation. One-on-one training on the use of the app was provided to all the case managers.
