HIVE adopts an Implementation Research Framework to support integrated care and management of HIV and concomitant NCDs leveraging an mHealth application tailored for the (self-)management of multiple long-term conditions for PLWH. This initiative also incorporates interpersonal counselling (IPC) for vital psychosocial support and integration of NCDs care into HIV clinics. The mHealth application will build on an existing digital health tool developed by HIVE partner, Columbia University, which has already been piloted in several low- and middle-income countries . HIVE aims to extend and customize the application for diverse high-income countries (HICs) and low- and middle-income countries (LMICs), including Kenya, Kazakhstan, Greece and Malta, addressing the unique needs of PLWH in different disease settings and cultural contexts. The goal is to mitigate the disparities in access to health for PLWH in different countries as well as the inequalities that are being faced among different population groups within each participating country.
