Fig. 1From: An electronic trigger tool to optimise intravenous to oral antibiotic switch: a controlled, interrupted time series studyInterrupted time series analysis of percentage of iv antimicrobial prescriptions >72 h. The grey area in the chart represents the pre-intervention period, the white area the post-intervention period. The squares represent the control group, where the triangles represent the intervention group. A trend line has been drawn through the data points for each group during the pre- and post-intervention period. The time series analysis demonstrated a significant decrease in the percentage of antimicrobial prescriptions in the intervention group (solid lines and solid double arrow, reduction 19.3%; p < 0.01) and in the control group (dashed lines and dashed double arrow, reduction 6.1%; p < 0.05), with an additional reduction of 13.2% (p < 0.05) in favour of the intervention groupBack to article page
