Abstract
Background: In Myanmar, using a mobile application (app) for tuberculosis (TB) screening and its operational effect on seeking TB health care has not been evaluated yet.
Objective: This study aims to report the usability of a simple mobile app to screen TB and comply with chest x-ray (CXR) examination among presumptive cases detected the app.
Methods: A new "TB-screen" app was developed from a Google Sheet based on a previously published algorithm. The app calculates a propensity TB risk score from an individual's socio-demographic characteristics and TB clinical history and suggests whether the individual should have a CXR. The screening program was launched in urban slum areas soon after the covid-19 outbreak subsided. A standard questionnaire was used to assess the app's usability rated by presumptive cases. Compliance to perform CXR was confirmed by scanning the referral QR code via the app.
Results: Raters were 453 presumptive cases detected by the app. Mean usability rating score was 4.1 out of 5. Compliance to have a CXR examination was 71.1% (n=322). Active TB cases detection among CXR compliances was 7.4% (n=24). One standard deviation increase in the app usability score was significantly associated with a 59% increase in odds to comply with CXR (β=.464) after adjusting for other variables (P<.001). Conclusions: This simple mobile app got the high usability score rated by 453 users. The mobile app usability score well predicted compliance to perform the CXR examination. Eventually, 24 out of 322 who were suspected by the mobile app were detected as the active TB cases by CXR. The system should be upscaled for a large trial. https://pubmed.ncbi.nlm.nih.gov/35623000/
