Operation ASHA (OpAsha) is an NGO in Cambodia (and India) that works closely with the government to implement the tuberculosis TB program and reach out to about 20% of the population in eight provinces. Cambodia is among the countries with the highest incidence of TB in the world. There are problems with lack of diagnosis and incomplete follow-up treatment, which results in undetected cases and the spread of the disease. With grants from ISIF, OpAsha developed a mobile App for TB detection in Cambodia: it bridges the gap between the Government’s TB programme and undiagnosed TB patients. Field supervisors visit families of existing patients, factories where patients work, and they also go door-to-door in areas they serve. The App serves to connect patients and form a wireless link with the microscopy centers so that no patient is lost to follow-up. With the App, OpAsha has increased accuracy of TB detection by 12%. The DECI-2 team worked with the manager of the project first on UFE and soon after on ResCom. The process allowed her to refine the project strategy and improve the communication of the findings with government and the World Health Organization. She commented that once she understood the UFE logic, it helps her develop the communication strategy.
