Author Information
Author(s): Yining Xu, Kevin Schwartzman
Primary Institution: Montreal Chest Institute
Hypothesis
What is the yield of the referral process for positive baseline tuberculin tests among new health care workers and students?
Conclusion
A small proportion of health care workers and students with positive tuberculin tests were eligible for and completed treatment for latent TB infection.
Supporting Evidence
- 87% of participants were foreign-born.
- 70% reported previous BCG vaccination.
- 33% were recommended treatment for latent TB infection.
- 79% of those recommended treatment began it.
- 70% of those who started treatment completed it.
Takeaway
This study looked at health care workers and students who tested positive for tuberculosis. Most of them didn't need treatment, and many who did start treatment didn't finish it.
Methodology
Retrospective cohort study reviewing charts of new health care students and workers referred for positive tuberculin tests.
Potential Biases
The study may not be representative of all patients or practitioners as it only considered patients seen at a single TB referral center.
Limitations
The study was limited to information documented during routine patient care and did not assess the yield of initial TST reading and referral.
Participant Demographics
Majority were foreign-born (87%), with a mean age of 33 years, and over two-thirds were female.
