Therefore, we need to predict familiarity scores of workers on landmarks using the latent similarity between workers and that of landmarks.
*TB, tuberculosis; HCW, healthcare worker; LTBI, latent TB infection; IGRA, interferon-γ release assay; TST, tuberculin skin test.
One of the important component of tuberculosis infection control is the routine screening of healthcare workers for latent tuberculosis infection and the administration of chemoprophylaxis to those who test positive.
IGRA is the most effective strategy when screening healthcare workers for latent or active TB.
Our study suggests that health gains justify IGRA costs when screening healthcare workers for latent or active TB.
However, compared with healthcare workers for latent TB infection, the caregivers of our study had higher prevalence of latent TB infection.
We develop and validate a new health economic model by comparing cost-effectiveness of tuberculin skin test (TST) and/or a tuberculosis (TB) blood test, interferon-gamma release assay (IGRA), in screening healthcare workers for latent or active TB.
Periodic testing of healthcare workers for latent TB and treating those with latent infections who are at high risk for progression to active TB might be feasible in selected settings, particularly among trainees and junior staff (who seem to be disproportionately affected).
The authors develop and validate a new health economic model by comparing cost-effectiveness of tuberculin skin test (TST); blood test, interferon-gamma release assay (IGRA) and TST followed by IGRA in conditional sequence, in screening healthcare workers for latent or active tuberculosis (TB).
We develop and validate a new health economic model by focusing on whether a tuberculin skin test (TST) and/or a blood test for tuberculosis (TB), interferon-gamma release assay (IGRA), is more cost-effective in screening healthcare workers for latent or active TB.
