Referring a patient directly to a specialist is a common practice in the medical field. This process involves a primary care physician sending a patient to a specialist for further evaluation and treatment. The term 'REFER' is used to describe this process, which is often abbreviated as 'D2S' or 'Direct to Specialist'. This practice is beneficial for both the patient and the specialist, as it allows the specialist to provide more specialized care and the patient to receive more timely and accurate treatment.
