Improvement Cycle for Tuberculosis Control in a Capital City of Northeastern Brazil
Tuberculosis, Primary Health Care, Quality Improvement.
Introduction: Tuberculosis is considered a public health problem in several countries, including Brazil, as it is one of the leading causes of morbidity and mortality in the population. It is an infectious and communicable disease caused by the etiological agent Mycobacterium tuberculosis and transmitted through aerosols. It is strongly associated with social inequalities and the living and health conditions of populations. In the effort to control it, it is necessary to develop actions within Primary Health Care to interrupt the chain of disease transmission, either through the active search for individuals with respiratory symptoms or through the investigation of contacts of bacilliferous patients. Objective: To improve the quality of the municipal tuberculosis control program in Natal/RN. Method: This is a quasi-experimental, before-and-after study with a quantitative approach, to be conducted through the implementation of a quality improvement cycle in the municipal tuberculosis control program in the city of Natal, Rio Grande do Norte. The study was approved by the Research Ethics Committee under CAAE: 93636925.6.0000.5292. The initial stages of the quality improvement cycle were carried out, namely: identification and prioritization of the problem through cause analysis and the establishment of criteria. Partial Results: According to data from the Notifiable Diseases Information System, in 2025 a total of 713 tuberculosis cases were reported in the municipality of Natal, of which 492 were new cases. Regarding the clinical form, there was a predominance of pulmonary tuberculosis. Latent tuberculosis infection accounted for 141 cases, of which 133 were new cases. It is noteworthy that, of the total cases, 97.9% had active tuberculosis adequately ruled out. Concerning the sociodemographic profile of individuals with TB, there was a predominance among males (66.4%), individuals aged 20 to 39 years (39.9%), with the highest representation among those identified as mixed race (67.7%), and with elementary education being the most frequently reported level of schooling (38.8%).
