Understanding responses to a renal dosing decision support system in primary care

Area of Science:

• Health Informatics
• Clinical Decision Support Systems
• Medical Quality Improvement

Background:

• Renal dosing clinical decision support (CDS) systems show promise for improving patient outcomes.
• High rates of alert overrides by healthcare providers are a significant challenge, limiting the effectiveness of CDS.

Purpose of the Study:

• To investigate the reasons behind provider overrides of renal dosing CDS alerts.
• To understand provider usage patterns and identify factors contributing to high override rates.

Main Methods:

• A stratified random sample of 300 renal dosing CDS alerts was selected from primary care practices.
• Electronic medical records were reviewed using established appropriateness criteria.
• An inter-rater reliability process ensured consistent evaluation of override reasons.

Main Results:

• Two-thirds of the evaluated renal dosing CDS alerts were inappropriately overridden.
• The proportion of inappropriate overrides was consistent across frequent and non-frequent over-riders.
• Provider override patterns indicate a need for enhanced acceptance of clinically sound recommendations.

Conclusions:

• Current renal dosing CDS systems face challenges with provider adherence, despite demonstrated clinical benefits.
• Strategies to improve provider acceptance of appropriate CDS suggestions are necessary.
• Targeted interventions are required to address the widespread issue of alert overrides and maximize patient safety.
