Usability of a mobile health application in tuberculosis screening and compliance to perform chest x-ray examination among presumptive cases detected by the app in Myanmar
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 project 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. This project 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%. 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:
Our findings revealed high usability of the app and compliance to perform CXR among the presumptive TB cases. However, further study should confirm the results when covid-19 pandemic is no more perceived as a serious threat.
