Cohort Review
A TB cohort review is a systematic evaluation of patients with TB disease and their contacts, and is used in countries around the world, including the United States. The cohort review process has proven to be a very useful tool for ensuring accountability, educating staff about protocols and goals, and improving case management and prevention. The TB cohort review process is used as a management tool that was designed to motivate staff, reveal program strengths and weaknesses, indicate staff training and professional education needs, increase staff accountability for completion of treatment for both TB disease and latent TB infection (LTBI), and improve TB case management and the identification of contacts.
The Michigan TB Control Program conducts cohort reviews quarterly (January, April, July, October) with any local health department that has reported at least one case with the previous 3 months.
