Latent Tuberculosis infection (LTBI) guidelines can be complex. LTBI-ASSIST is a web-based interactive tool to navigate US LTBI clinical practice guidelines in a patient-centered format that may guide clinical decision making around Latent TB care.

The research goal is to determine the difference in reported confidence among trainees that are not experts in LTBI care. The investigators further aim to assess if access to the LTBI-ASSIST tool improves clinical decision making in a series of simulated case scenarios containing guideline-derived, multiple choice items, as well as assess the efficiency in navigating the scenarios - measured by time to complete the survey.

The investigators proposed a randomized study design, in which an electronic survey/questionnaire with 4 case scenarios consisting of 14 multiple choice questions. Participants providing informed consent will be randomized to receiving access to either US Centers for Disease Control (CDC)/National Tuberculosis (TB) Controllers Association (NTCA) Guidelines or the LTBI-ASSIST online tool. Those in the experimental arm will further complete a 10 question System Usability Scale to assess usability of the LTBI-ASSIST tool.

All Johns Hopkins medical trainees and residents will be eligible to participate.
