What precautions should be taken when transporting a hospitalized patient with suspected tuberculosis to rule out the diagnosis?

Transporting a Patient with Suspected TB in Hospital

When transporting a hospitalized patient with suspected tuberculosis, the patient must wear a surgical mask or valveless particulate respirator, transport should be minimized and expedited, the destination department should be notified in advance, and healthcare workers performing procedures should wear N95 respirators (or equivalent particulate respirators). 1

Patient Precautions During Transport

The patient is the primary source control:

• Place a surgical mask or valveless particulate respirator on the patient before leaving the isolation room 1
• Keep the patient masked throughout the entire transport
• Instruct the patient to cover their mouth and nose when coughing or sneezing 1

Healthcare Worker Protection

Personnel involved in transport and procedures must protect themselves:

• All healthcare workers performing procedures on the patient should wear N95 respirators (or NIOSH-approved equivalent particulate respirators), especially if the procedure induces coughing 1
• Emergency transport personnel should wear particulate respirators if the patient cannot tolerate a mask 1
• For ambulance transport, keep rear windows open and set ventilation to non-recirculating mode when feasible 1

Minimize and Expedite Transport

The fundamental principle is to reduce movement of potentially infectious patients:

• Perform procedures at bedside whenever possible to avoid transporting the patient 2
• Only transport for procedures that are absolutely necessary and cannot be done at bedside 2
• Return the patient to the isolation room as quickly as practical after the procedure 1
• Minimize time spent in common waiting areas 1

Destination Department Preparation

The receiving area must be prepared and notified:

• Inform the destination department of the patient's infectious or potentially infectious status before transport 2
• Ideally, use a specially ventilated area in the treatment or radiology department that meets airborne isolation standards (at least 6 air changes per hour) 1
• If special ventilation is unavailable, minimize the patient's time in the procedure area

Post-Transport Disinfection

After the patient leaves:

• Disinfect transport equipment and the procedure area according to infection control guidelines 2
• Clean both before and after the procedure if the area will be used for other patients 2
• Allow adequate time for air exchange before using the room for another patient (time varies based on ventilation efficiency—typically 99% of airborne contaminants removed) 3

Common Pitfalls to Avoid

1. Don't confuse surgical masks with N95 respirators: Surgical masks are adequate for the patient and for protection against droplet transmission, but healthcare workers need fitted N95 respirators for airborne precautions with TB 4

2. Don't delay necessary procedures: While transport should be minimized, don't withhold essential diagnostic or therapeutic procedures. The key is proper precautions, not avoidance 2

3. Don't forget to document: Keep a record of all personnel involved in transport and procedures with potentially infectious patients 5

4. Remember that most children with TB are not contagious: Children under 12 years with pulmonary TB are typically not infectious, though adults accompanying them may be 4

The evidence consistently emphasizes that source control (masking the patient) combined with respiratory protection for staff (N95 respirators) are the cornerstones of safe transport 1. These measures, combined with minimizing transport duration and proper environmental controls, effectively prevent nosocomial transmission during necessary patient movement within the hospital.
