First used to describe the HIV epidemic in Washington DC, the care cascade model has proved an effective tool for evaluating the epidemic across a wide range of geographic and clinical settings. The model defines an outcome that patients should achieve – virologic suppression in the case of HIV – and outlines a series of sequential steps needed to achieve the outcome (diagnosis, linkage to care, retention in care, prescription of antiretroviral therapy and viral suppression). The authors believe that TB control programs can learn from the human immunodeficiency virus (HIV) community’s systematic use of care cascades, not only to identify the missing cases, but also as a tool for delivering comprehensive, patient-centered programs.
