Clinical Decision Support for Medication Safety
Medication Safety3 sources · Updated Oct 19, 2026
This review helps pharmacists judge what rule-based and machine learning (ML) decision support can and cannot deliver, and how to build pharmacist workflows that turn alerts into safer prescribing.
Bottom Line
Across renal dosing, anticoagulant screening, and intensive care unit (ICU) interaction alerting, clinical decision support systems (CDSS) reliably surface prescribing problems but have no proven effect on clinical outcomes, so their value depends on pharmacist triage, alert stratification, and local implementation quality.

State of Play
Current evidence shows CDSS consistently improve proximal process measures such as renally appropriate dosing, chronic kidney disease (CKD) documentation, and detection of anticoagulant orders that need review. All three analyses grade the evidence as low and hypothesis-generating. None demonstrates reductions in mortality, bleeding, thromboembolism, or CKD progression.
