This study assessed the effectiveness of standard antileishmanial treatments using a community-based approach supported by mobile health (mHealth) in three rural areas of Colombia. From January 2018 to September 2021, we assessed treatment outcomes, adherence, and adverse drug reactions in CL patients, with the support of the Guaral+ST app. Treatment decisions were made by providers at health facilities at each site in accordance with national guidelines, whereas treatment follow-up and presumptive case identification were made by trained community leaders and health agents at the community level. In total, 231 participants received antileishmanial treatment (63 received miltefosine, 110 meglumine antimoniate, and 58 pentamidine). Disease presentation was mild (median number of lesions = 1, interquartile range [IQR]: 1-2) and of short duration (1.5 months, IQR: 1-3). The strategy yielded information on the therapeutic outcomes in 81% of study participants. Effectiveness, measured as the proportion of cure at 90 to 180 days, was 86.3% (95% CI: 73.3-93.48) for miltefosine; 77.6% (67.5-85.3) for meglumine antimoniate, and 73.1% (59.0-83.6) for pentamidine. The effectiveness of pentamidine in children ≤10 years old was 79.4% (61.6-90.3). This is one of the few reports of effectiveness of pentamidine in children with prospective data collection in the Americas. Adverse drug reactions occurred in 32% of patients, most frequently with meglumine antimoniate. Our findings demonstrate that standard antileishmanial treatments are effective in rural areas where the disease is endemic and that mHealth has a pivotal role in improving patient follow-up and data collection on therapeutic outcomes.</p>  a1476-1645
