Occupational asthma (OA) is one of the most common occupational lung diseases. There are currently about 300 documented asthmagens. Patients have a chance to be cured if the OA is handled correctly. Diagnostic delay is often due to the attending not taking the occupational history. The aim of our study was to develop a web application that would deliver fast and accurate information. Methodology: The three phases of web application development were included. Sourcing input data from a systematic review of 1,403 studies found when searching for review and systematic review and full text and inclusion criteria. A total of 276 eligible studies were selected, and after reviewing abstract, 25 were fully reviewed and summarized into 2 groups-14 high molecular weight agents and 14 low molecular weight agents. The industrial code was then reviewed, and prototypes developed. Evaluation of prototypes for System Usability Scale (SUS) by experts was performed. The expert suggestions were reviewed and revised to create a second prototype. Trialing web application for use by primary care physicians. The final web application was evaluated by primary care physicians was implemented. The median of SUS was 75, which is greater than the average. In future, we seek to develop tools for analyzing the probability of diagnosing OA, which would help making diagnosis more convenient. The earlier diagnosis can be achieved, the better the prognosis.
