Prevalence of Latent Tuberculosis Infection in Health-care Workers &

Status Recruiting

Clinical Trial Summary

This study is a cross-sectional study that examines the prevalence of Latent Tuberculosis Infection [LTBI], defined as individuals infected with Mycobacterium tuberculosis with no clinical evidence of disease, and the possible risk factors of LTBI in a large cohort of health care workers (HCWs) and students.

Clinical Trial Description

Mycobacterium tuberculosis may develop symptoms and signs of disease or may have no clinical evidence of disease (latent tuberculosis infection [LTBI]). TB disease remains one of the major causes of morbidity and mortality in the world. A survey to assess the prevalence of the individuals with a LTBI and evaluate the potential main risk-factors will be performed on both HCWs and students attending the hospital wards, trained at Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome. This study is a cross-sectional study that examines the prevalence of Latent Tuberculosis Infection [LTBI], defined as individuals infected with Mycobacterium tuberculosis (MT) with no clinical evidence of disease, and the possible risk factors of LTBI in a large cohort of health care workers (HCWs) and students. The study will involve all HCWs of Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome - a tertiary reference hospital with over 1,500 beds - and all students of all three-year and single-cycle degree courses, master's degree courses, graduate schools of the faculty of Medicine and Surgery of the Catholic University of Sacred Heart in Rome, trained at the Fondazione Policlinico Universitario A. Gemelli IRCCS. All enrolled participants, who will agree to participate to the study and answer the questionnaire, will respond a cross-sectional questionnaire survey through dedicated tablet. The survey will contain a brief explanation of the study aims and an invitation to respond to a 9 items multiple choice questionnaire. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
