Physicians' Compliance with a Clinical Decision Support System Alerting during the Prescribing Process

Area of Science:

• Clinical Informatics
• Pharmacovigilance
• Health Informatics

Background:

• Clinical decision support systems (CDSS) can enhance practitioner performance in preventing medication errors.
• Traditional methods involving patient lists and telephone calls are less efficient.
• Integrating real-time alerts into the medication ordering workflow is crucial for CDSS success.

Purpose of the Study:

• To evaluate the effectiveness of a CDSS that provides real-time alerts during medication ordering.
• To assess adherence to specific recommendations aimed at preventing common medication errors.
• To determine if the implemented CDSS improved prescribing practices for methotrexate, bisphosphonates, and hyponatremia management.

Main Methods:

• Implementation of three algorithms within a CDSS to generate alerts during medication ordering.
• Analysis of prescribing data for specific drug interactions and conditions before and after CDSS implementation.
• Utilized Pearson's Chi-squared test to compare adherence rates.

Main Results:

• Co-prescription of folic or folinic acid with methotrexate increased from 54% to 91% (p=0.014).
• Co-prescription of vitamin D or analogues with bisphosphonates rose from 11% to 40% (p=0.001).
• Discontinuation of sodium-lowering drugs in hyponatremic patients increased from 3% to 14% (p=0.002).

Conclusions:

• The CDSS effectively improved physician prescribing behavior by providing timely alerts for preventable medication errors.
• Real-time alerts integrated into the ordering process are a successful strategy for enhancing medication safety.
• This approach demonstrates the value of CDSS in optimizing clinical practice and patient outcomes.
