Latest highlights on drug safety and efficacy

Electronic drug–drug interaction (DDI) alerts are a core component of medication safety. A 2025 systematic review (8 studies; N=43,413) found that DDI alerts increase targeted clinician actions, such as modifying prescriptions or ordering monitoring tests (OR 2.08; 95% CI 1.01–4.27). Effects were strongest when alerts were clearly actionable and clinically relevant (1).

While evidence for downstream patient outcomes remains limited, the review provides important insight into why: many systems relied on broad, non–patient-specific rules and generated high alert volumes (1).

How to maximise clinical relevance while minimising burden:

• Prioritise high-risk DDIs (e.g., serious, well-established interactions) rather than alerting on theoretical combinations
• Integrate patient-specific context (labs, renal function, comorbidities, current doses) to improve clinical relevance
• Design actionable alerts with clear next steps (dose adjustment, monitoring recommendation, alternative drug)
• Avoid unnecessary “hard stops”; use interruptive alerts selectively for highest-risk scenarios
• Measure performance locally: track override patterns, monitoring completion, and incidence of preventable DDI-related harm

Drug–drug interaction decision support can improve patients’ outcomes. The path to do so lies in precision, relevance, and continuous optimization of alert design. Don’t settle for less.

The value of drug–drug interaction decision support lies in precision: delivering the right alert, for the right patient, at the right moment. Clinically relevant, patient-specific alerts support safer prescribing while minimising alert fatigue.
