d. Provide the number of designated TB exam/treatment or special procedure
rooms as determined below using the potential S/KI TB patient visit estimate generated in I.1 C
above.

modules to meet local operating procedures and needs.
2. Facility/air:
a. Meet at a minimum current CDC guidelines for unscheduled areas and high risk
clinics
b. Meet at a minimum current CDC guidelines for ventilation and airflow for S/KI
TB:
(1) Emergency area Isolation room(s) (anteroom not required)
(2) ENT room(s)
(3) Aerosolized pentamidine room(s)
(4) Designated exam/treatment/procedure room(s)
3. Unscheduled areas
All unscheduled ambulatory care areas and associated waiting areas should have ventilation designed
and maintained to reduce the risk of tuberculosis transmission. Germicidal UV lamps andlor HEPA
filters may provide additional benefit when used to supplement ventilation, particularly in facilities
located in areas of high incidence for TB.
4. Scheduled areas (clinics)
All scheduled areas serving patients who are at high risk for TB transmission should be designed to
reduce the risk of TB transmission. Air from clinics serving patients at high risk for TB should not be re-
circulated unless it is first passed through an effective high-efficiency filtration system (HEPA filters are
currently the effective high-efficiency filtration system available).
5. Designated exam/treatment rooms for SIKI TB
VHA ambulatory care programs in Medical Centers and in satellite/independent outpatient clinics must
have some facilities that are adequate to deal with SIKI TB patients. These TB rooms can
