Factors Related to Delayed Diagnosis of Cutaneous Melanoma in the Brazilian Public Health System

In Brazil, 75% of the population uses the Sistema Único de Saúde (SUS), public health system, where the general practitioner (GP) is responsible for melanoma diagnosis. Identify the factors related to the delay in diagnosing melanoma patients assisted by SUS. A prospective observational study based on a questionnaire and medical records review assessed the sociodemographic features, melanoma signs and symptoms, previous knowledge of the disease, and factors related to delays in seeking medical care. One hundred sixty-six patients were included. Healthcare professionals suspected a lesion in only 23.5% of cases. The average time between lesion suspicion by patient/relative and first medical appointment with GP was over 6 months (31%). The time between the first GP exam and biopsy conducted by a specialist ranged from less than 1 month (34.9%) to more than 1 year (18.7%). Half of the patients (49.4%) experienced delays in histopathological diagnosis due to SUS bureaucracy/slowness. Most (80%) patients did not know what melanoma was before diagnosis. Delay in melanoma diagnosis was related to a lack of knowledge about the disease's signs and symptoms for both the study population and the primary physicians, indicating that both players must receive proper education about melanoma. Also, the infrastructure and work processed at SUS impeded the patient flow, contributing to the diagnosis of the lesions at more advanced stages.
