In India, tuberculosis (TB) notification has been required since 2012. Notwithstanding, notification rates remain low. Non-reporting of tuberculosis cases not only results in an underestimation of cases, but also impedes the country's TB control strategy. Our research aims to assess practitioners' awareness, perception, and practice of tuberculosis case notification, as these factors can help reduce the TB burden. A cross-sectional study of 142 physicians was conducted between August 2018 and December 2019. Doctors were interviewed and given evaluation forms. Seventy-seven percent of the 142 physicians polled worked in medicine-related specialties, while 33% worked in surgery. Public sector physicians (64.7%) knew more about the Nikshay App than private practitioners (40.8%). The vast majority of public-sector doctors were only notified through their hospital's National Tuberculosis Elimination Programme (NTEP) center. However, the majority of private practitioners (47.8%) notified cases directly through the hospital, the local District Tuberculosis Officer (DTO) or NTEP medical officer (24 percent), or the Nikshay portal (28%), whereas the majority of public sector doctors notified only through the hospital NTEP center (85.9%). The primary reasons for non-notification are the high patient load on doctors, a lack of understanding about Nikshay App and its functionality, technological difficulties in using the Nikshay App, and the stigma associated with tuberculosis. The Nikshay App must be popularized as a notification mechanism through the NTEP program. To increase notification rates, practitioners must overcome the challenges they face. In terms of notification, more seminars and training, particularly hands-on training, should be held on a regular basis.
