Summary
Physicians with access to electronic medical records (EMR) adjusted their laboratory ordering habits. This demonstrates how EMRs influence physician behavior by providing contextual patient data.
Area of Science:
- Medical Informatics
- Health Services Research
Background:
- Electronic medical records (EMR) provide physicians access to patient data.
- Integrating laboratory results into patient history is crucial for clinical decision-making.
Purpose of the Study:
- To evaluate if physicians with EMR access alter their laboratory ordering habits.
- To compare changes in lab order volume between physicians with and without EMR access.
Main Methods:
- Longitudinal study design using electronic medical record data.
- Tracking daily laboratory order volumes for physicians with and without EMR access.
- Utilizing a matched control group for comparison.
Main Results:
- Physicians with EMR access demonstrated significant changes in laboratory ordering habits.
- EMR access facilitated the contextual use of laboratory results within patient medical history.
Conclusions:
- Electronic medical records significantly influence physician laboratory ordering behavior.
- EMR systems enable physicians to better integrate lab results into clinical practice.
