DOP, or Directly Observed Therapy, is a treatment strategy used primarily in managing infectious diseases like tuberculosis. In this approach, a healthcare provider directly observes a patient taking their medication to ensure adherence to the prescribed regimen. This method helps improve treatment outcomes and reduces the risk of drug resistance. The DOP strategy is particularly important in public health, as it not only supports individual patients but also contributes to controlling the spread of diseases. By ensuring that patients complete their treatment, DOP plays a crucial role in safeguarding community health and preventing outbreaks.
