ABSTRACT The study aimed to analyze the impact of health interventions carried out in the city of Palmas, Brazil, on the epidemiological and operational indicators of leprosy between 2007 and 2017. The intervention consisted of training healthcare personnel on the diagnosis and follow-up of patients and organizing the referral of patients to health units. Estimates of the impact were calculated by taking the differences between indicators reported in two equal periods of 1.5 years pre- and post-intervention, with a transition period of six months. During the study period, the database contained 1,875 notifications, with 66% of cases diagnosed in the post-intervention period. There was a predominance of males (52%); aged 50 years or more (34.9%); with mixed ethnicity (63.5%). The low level of education was noticeable, with more than half of the cases (51.7%) reporting illiteracy or ≤ 7 years of education. The intervention resulted in an increase in both, epidemiological and operational indicators, suggesting a positive impact of the intervention on leprosy detection and treatment. Our results also emphasize the need for further studies addressing the impact of pragmatic health interventions aiming at controlling and eliminating the disease.
