Evaluation of computerized clinical decision support providing evidence-based information

Author	Population	CCDS provided	Measured outcomes/results	Authors' conclusion
Christakis* et al, 200145	Outpatient academic pediatric clinic	Provided evidence-based information about antibiotic selection and duration at the time of prescribing an antibiotic for AOM	Overall increase from 50.7 to 69.7% in antibiotics ordered for <10 days. A 44% greater increase in frequency of ordering antibiotics for <10 days from baseline in prescribers exposed to literature evidence vs a 10% change in frequency in the control group (p<0.01). Prescription of any antibiotic increased from baseline	Presenting pertinent information to providers during decision-making improved prescribing patterns
Davis* et al, 200746	Two outpatient academic pediatric clinics	Provided evidence-based treatment information at the time of prescribing medications for AOM, allergic rhinitis, sinusitis, constipation, pharyngitis, croup, and urticaria	Increased prescribing in accordance with treatment evidence by 4% (38% to 42%) in the intervention versus 1% in the control group (39% to 40%) (weighted 8% difference with a CI of 1% to 15% difference)	Significant improvement in provider prescribing practices for a given indication when evidence was provided during prescribing
