Engaging frontline providers: an important key to eliminating tuberculosis in Canada, and other high-income countries

Heffernan, Courtney; Rowe, Brian H.; Long, Richard

The greatest human cost of the rapidly moving pandemic of SARS-CoV-2 may be due to its impact on the response to other diseases. One such other disease is tuberculosis (TB). All indications suggest that COVID-19-related diversions of healthcare resources and disruptions to public health programming will exacerbate the slower moving pandemic of TB. This is expected to set back TB elimination efforts by years. This is a prediction that is especially relevant to Canada, which has repeatedly failed to meet pre-set targets for the elimination of TB even before the COVID-19 pandemic began. A collaborative approach to achieve TB elimination, one that engages all care providers, has recently been emphasized by the STOP-TB Partnership. Among TB elimination strategies, frontline providers (e.g., family physicians, emergency room physicians, and others) are well positioned to identify candidates for the treatment of latent TB infection, and make the diagnosis of infection-spreading cases of TB in a timely manner, thereby interrupting forward-moving chains of transmission. Electronic medical records offer the promise of automating these processes. In this commentary, we promote broader engagement of the workforce across multiple sectors of medicine to reduce TB associated morbidity and mortality, interrupt transmission, and shrink the reservoir of latent TB infection.
