Clinical Trial Summary

This is a stepped-wedge, cluster-randomized, two-arm, open-label, clinical trial of an electronic clinical decision support tool (eCDST) for the diagnosis and treatment of lower respiratory tract infection (LRTI) among patients at three sites in Southern Province, Sri Lanka. The primary objective of this trial is to determine the impact of an electronic clinical decision support tool (eCDST) on clinical outcomes and antibacterial prescription in subjects with LRTI in the intervention group compared to the control group. The study will enroll 765 patients ≥ 14 years of age. Medical wards will be randomized in clusters to the intervention at intervals of 3-6 months until all clusters cross over. Participants will be followed for 30 days from enrollment to record clinical outcomes and any antimicrobials prescribed.
