BACKGROUND: There is limited access to radiology facilities in most parts of India leading to significant under diagnosis and underreporting of smear negative clinically diagnosed tuberculosis (CDTB). Public Private Partnership (PPP) has a lot to contribute towards addressing this gap through providing access to chest x-ray (CXR) in far-off locations. METHOD: Mobile vans equipped with digital CXR equipment and support staff were provided by a Corporate Hospital working closely with government, with scheduled visits to government peripheral health institutes. Patients received upfront CXR and sputum microscopy along with GeneXpert in accordance with the revised TB diagnostic algorithm prescribed by the national program, Following a successful pilot in 2014 in district Rewari, "TB free Haryana" was launched in November 2015 with a phased roll out in 16 districts by 2018. RESULTS: The pilot initiative in 2014 confirmed practical and clinical feasibility and revealed a high rate (30% of people screened) of CDTB i.e. symptomatic cases with radiologic abnormalities compatible with Pulmonary TB. In the first year (2016), 5 districts were covered and a total of 3340 CXRs were carried out. There was an increase in the case notification rates of new CDTB (smear negative) in 2016 compared to 2015 (p = 0.036); yielding an additional 180 cases and an 11.67% increase in case detection. Scale up to a total of 13 and 16 districts took place successfully in 2017 and 2018 respectively; with 6268 CXRs and 8021 CXRs done in the respective years. CONCLUSION: PPP can involve Corporate Hospitals to improve the existing diagnostic infrastructure and provides access to CXR in a not-for-profit sustainable collaboration, with scale-up to the state level; and potential to replicate this initiative in other states.
