Epidemiological profile of Brazilian oncological patients seen by a reference oncology center of the public health system and who migrate in search of adequate health care.

INTRODUCTION
Structural disparities between different Brazilian regions in public health system cause patients to migrate in search of better conditions to treat their diseases. Besides patient's discomfort, there is a concentration of care in large centres, causing overload to current capacity.


OBJECTIVE
To evaluate migratory flow and associated factors in a reference service in oncology.


METHODS
Cross-sectional study conducted at a referral oncology service in Great ABC region of São Paulo. Patients were interviewed, and clinical and demographic data collected.


RESULTS
Between March-July 2016, 217 patients were included. Analysis showed a divergence between the postal code registered in the medical record and that recorded during the interview in approximately 10% of cases. Of these, 42.9% were residents of other states. Search for treatment motivated most patients to seek service outside their city.


CONCLUSION
Results reflect the informal search for medical care outside the home area. Besides the direct impact on patients' quality of life, migratory flow has an economic-social impact because these patients place a burden and impose costs on services of cities where they do not perform their responsibilities as citizens. Confirmation of the existence of a significant migratory flow demonstrates the need to discuss restructuring public health policies.
