Primary outcome parameters. During the post-implementation period, a trend in decrease in no. of patients prescribed antibiotics a at ED discharge (ꞵ, − 0.745; 95% CI, -1.6–0.1; P = 0.093), and b a significant decrease at admission (ꞵ,− 1.2; 95% CI, − 2.0–− 0.4; P = 0.003). Furthermore, c) a significant immediate increase in the number of consults made to infectious disease specialists regarding isolation precautions (Δ in intercept, 0.031, SE, 0.010, P = 0.002) after the incorporation of syndromic gastrointestinal panel testing in the pediatric emergency department, as well as d) a significant immediate decrease in the time taken to exercise appropriate isolation precaution measures to patients at wards (Δ in intercept, -1.397, SE, 0.455, P = 0.003)
