Three doctors in the Wielkopolska region of Poland are under investigation after issuing a combined total of over 56,600 medical leave certificates in the past year. The Social Insurance Institution (ZUS) initiated investigations into all three physicians, raising concerns about potential irregularities. The probe focuses on verifying whether the doctors conducted the legally required direct patient examinations before issuing the certificates. This unusually high number of sick leave approvals triggered the ZUS review. Authorities are assessing whether the certificates were issued appropriately and in accordance with medical standards. The investigation aims to prevent potential abuse of the sick leave system and ensure proper medical practice. Further details regarding the specifics of the alleged irregularities have not yet been released.
