The aim of this study was to assess the output (in number of procedures) of the Brazilian hospitals accredited for the treatment of CLP patients, examine the referral flow of patients requiring this type of care, and ascertain the adequacy of the corresponding infrastructure of these healthcare facilities. Methodologically, the study used an observational, cross-sectional, and ecological design. Output data, categorized by state and macro-region, and patient referral flow records were accessible through the Outpatient Information System (SIA, in its Portuguese acronym) and the Hospital Information System (SIH, in Portuguese), respectively. Infrastructure assessment relied on data sourced from the National Register of Health Establishments (CNES, in Portuguese). Analysis encompassed data from 28 accredited hospitals. Concerning output metrics, the state of São Paulo ranked first in the number of procedures conducted. The establishments exhibiting the lowest output performance comprised six hospitals located in the Southeast region and two in the Center-West region. Examination of patient referral flow corroborated the concentration of procedures predominantly conducted in the Southeast, notably within São Paulo state. Infrastructure evaluation encompassed the following categories: physical facilities, diagnostic and therapeutic support services, equipment, and comprehensive multidisciplinary care services. The data showed that roughly 61% of the hospitals surveyed possessed less than half of the recommended items. The primary deficiency identified pertained to inadequacies in equipment availability. Conversely, the best outcomes were associated with diagnostic and therapeutic support services.

This study utilized a pre-/post-intervention design, including a pre-intervention questionnaire with 20 close-ended questions, an educational intervention, and a post-intervention questionnaire with nine close-ended questions. Descriptive and statistical analyses were performed using SPSS 25 and GraphPad Prism 8 software. The significance level was set at p = 0.05.

Although participants habitually ask about cigarette use, other forms of tobacco consumption are frequently overlooked. Most participants reported never having attended TCC training during their undergraduate studies (67.0%) or after graduation (71.2%). However, 96.2% showed interest in attending TCC training.
