OPD, or Outpatient Department, is a crucial part of any hospital or healthcare facility where patients receive medical consultations and treatment without being admitted to the hospital. It serves as the first point of contact between patients and doctors, allowing individuals to seek medical advice, undergo diagnostic tests, receive prescriptions, and follow up on treatments—all on the same day. OPDs are typically organized by specialty, such as general medicine, pediatrics, dermatology, orthopedics, and more, ensuring that patients receive expert care based on their specific needs. This system is essential for managing non-emergency medical issues efficiently, reducing the burden on inpatient services, and promoting preventive healthcare through early diagnosis and intervention.
