We assessed the contribution of active versus passive case-[...]texto impreso
Wingfield, Tom ; Boccia, Delia ; Tovar, Marco ; Gavino, Arquimedes ; Zevallos, Karine ; Montoya, Rosario ; Lonnroth, Knut ; Evans, Carlton A. | Public Library of Science | 2020-06-10T18:12:16ZBACKGROUND: Even when tuberculosis (TB) treatment is free, hidden costs incurred by patients and their households (TB-affected households) may worsen poverty and health. Extreme TB-associated costs have been termed "catastrophic" but are poorl[...]texto impreso

Cash transfers are key interventions in the World Health Organisation’s post-2015 global TB policy. However, evidence guiding TB-specific cash transfer implementation is limited. We designed, implemented and refined a novel TB-specif[...]texto impreso

However, diverse methods have been published. We aimed to optimise F[...]texto impreso

METHODS: Participants were recruited in 32 Peruvian communities [...]texto impreso
