Community led monitoring via OneImpact App. has been initiated in 4 TB-REP countries to register barriers faced by TB patients, provide real time case by case support and generate data for NTP and local authorizes to inform systemic changes. The adaptation of the OneImpact to country context has been finalized and the tool is currently rolled out in Azerbaijan, Belarus, Kyrgyzstan, Ukraine (Ukraine started earlier with STBP support) and Kazakhstan started the adaptation process of the digital tool in August 2020. Mechanisms for data exchange between the responsible CSO and NTP are established in each country. The monitoring reports on existing barriers based on data in OneImpact are expected to become part of the NTP M&E framework and complement the routinely collected data on services with patients’ feedback on timeliness, quality, accessibility and acceptability. Information from TB patients is collected in 4 TB-REP countries to inform decision making on transformation of the TB care system. Azerbaijan, Belarus, Kyrgyzstan, Tajikistan (the first implementer of OneImpact tool supported by STBP) and Ukraine civil society partners are invited at the session with a brief information on the process of implementing the CBM using the OneImpact mobile application, the main challenges during the implementation of the CBM using the OneImpact mobile application and lessons learned.
