Minimizing electronic health record patient-note mismatches

Area of Science:

• Health Informatics
• Medical Record Management
• Patient Safety

Background:

• Patient-note mismatches, where clinical notes are incorrectly associated with a patient, represent a potential risk in electronic medical records.
• While often infrequent, these errors can have significant implications for patient care and data integrity.
• Previous research indicates varying rates of documentation errors, highlighting the need for effective error reduction strategies.

Purpose of the Study:

• To quantify the prevalence of patient-note mismatches in an electronic medical record system.
• To evaluate the effectiveness of a user interface intervention (pop-up window) in reducing these mismatches.
• To assess the rate at which clinicians detect patient-note mismatches.

Main Methods:

• A pre- and post-intervention study design was employed to measure the rate of patient-note mismatches.
• The intervention involved implementing a pop-up window alert within the electronic medical record system.
• Prevalence rates were calculated using confidence intervals (CI) to assess statistical significance.

Main Results:

• The rate of patient-note mismatches decreased from 0.5% (95% CI 0.2% to 1.7%) before the intervention to 0.3% (95% CI 0.1% to 1.1%) after the intervention.
• This reduction in mismatch rates was found to be statistically significant.
• Clinicians identified patient-note mismatches in approximately 0.05-0.03% of notes, representing about 10% of all actual mismatches.

Conclusions:

• User interface design, specifically through interventions like pop-up windows, can significantly reduce patient-note mismatches in electronic medical records.
• Despite low overall prevalence compared to other documentation errors, patient-note mismatches remain a concern that warrants targeted mitigation strategies.
• Further improvements in electronic medical record system design are crucial for enhancing patient safety and data accuracy.
