We conducted a meta-analysis of the effect of CDSSs on length of stay (Figure 3). Of the six studies, five (83.3%) provided the necessary endpoint data to be included in meta-analysis. The interventions included recommendations for appropriate antibiotic therapy, guideline-based reminders for corollary orders, diagnostic management of children with fever, risk assessment calculators for infection and antibiotic treatment recommendations, and guideline-based diabetes testing recommendations. The combined relative risk for all studies was 0.96 (95% CI 0.88 to 1.05). However, if the Roukema et al.31 study, which was conducted in the pediatric population in the emergency department setting rather than the hospital setting, was excluded from the analysis, the combined relative risk for all studies was 0.91 (95% CI 0.86 to 0.97).
