A systematic review of evidence that was published after
release of the 2005 CDC guidelines for preventing Mycobacterium tuberculosis
transmission in health care settings found that a low percentage of health care
workers have a positive tuberculosis (TB) test at baseline and upon serial
testing. The CDC published its conclusions in the May 17 Morbidity and
Mortality Weekly Report.
Health care workers should be considered to be at
increased risk for TB if they answer “yes” to any of the following statements:
·
Residence for a month or more
in a country with a high TB rate
·
Current or planned
immunosuppression, including HIV
·
Receipt of an organ transplant
·
Treatment with a tumor
necrosis factor-alpha antagonist, chronic steroids, or other immunosuppressive
medication or
·
Close contact with someone who
has had infectious tuberculosis since the last test.
The updated recommendations for testing US health care personnel
include:
·
Screening for TB with an
individual risk assessment and symptom evaluation at baseline (preplacement)
·
TB testing with a tuberculin
skin test for people without documented prior latent TB
·
No routine serial TB testing
at any interval after baseline in the absence of a known exposure or ongoing
transmission
·
Encouragement of treatment for
all health care personnel with untreated latent TB, unless treatment is
contraindicated
·
Annual symptom screening for
health care personnel with untreated latent TB, and
·
Annual TB education of all
health care personnel.
