Furthermore, as time passed in the post-implementation period, a decreasing trend in number of patients prescribed broad spectrum antibiotics at ED discharge (ꞵ, -0.745; 95% CI, -1.6–0.1; P = 0.093), and a significant decrease at admission (ꞵ, -1.2; 95% CI, -2.0–-0.4; P = 0.003) was observed (Fig. 4 a, b).
