CONCLUSIONS • HH-DOTS is more costeffectivethantraditional DOTS: • - mean cost per case successfullytreated - (cost–effectiveness ratio) • - cost per additional case succesfullytreated - (incremental costs) • lowerwith HH DOTS thanwithtraditional DOTS • biggestburden of DOTS costsisonpatients and theirfamilies, • under HH-DOTS thisportiondecreases. • Resultsconsistentwiththosefoundbyotherswhoevaluated • Cost-Eff of ambulatoryapproachesto DOTS: • - Prado et al (2011 ) - Cad SaudePublica 27(5):944-52 - Brazil • - Ngandaet al (2003) - IJTLD 7 Suppl 1: S14-20 - Kenya • - Floyd et al (2003) IJTLD 7 Suppl 1: S29-37 - Malawi
