Direct observation therapy (DOT) is recommended by the WHO to promote adherence in the management of tuberculosis (TB) and this approach was adopted in 187 countries by 2005 (WHO, 2010). DOT allows assessment of correctly taking and completing therapy, but also can be valuable to promote adherence to medication use. DOT involves a healthcare professional observing patients taking their medication at home or in the clinic (Dosumu, 2001; Otu, 2013). The DOT approach to TB management has been utilised successfully in different countries as this approach has been shown to enhance medication adherence, improve outcomes including microbiologic success, and decrease acquired drug resistance to therapy (Favorov et al., 2012; Walley et al., 2001; Pasipanodya and Gumbo, 2013).
