What is the best course of action if a patient suspected of having active TB is to have dialysis?

In the case of a patient suspected of having active tuberculosis (TB) who is scheduled for dialysis, it is critical to prioritize both patient and staff safety due to the infectious nature of TB. Asking the patient to wear a mask is an immediate action that helps to minimize the spread of respiratory droplets that may contain the TB bacteria. This is a standard precautionary measure to protect others in the healthcare environment.

Additionally, calling the physician is essential to ensure that the patient's treatment can be safely managed, considering their suspected active TB status. The physician can then determine if further measures, like additional isolation or adjustments to dialysis procedures, need to be taken. This approach aligns with infection control protocols and ensures that the healthcare facility is prepared to provide care for the patient while mitigating risks associated with TB transmission.

In contrast, starting treatment as scheduled without delay could expose staff and other patients to potential infection. Placing the patient in isolation until further notice may be necessary eventually, but immediate actions such as wearing a mask and consulting the physician provide a swift response to the situation. Consulting with a TB specialist is a prudent step, but it is not the first priority before ensuring that the patient has protective measures in place to reduce the risk of disease spread.
