Emergency department (ED) physician workload perception showed weak correlation with electronic medical record (EMR) data. Objective EMR measures do not fully capture clinician workload in the ED.
Area of Science:
- Emergency Medicine
- Health Informatics
- Healthcare Management
Background:
- Emergency department (ED) workload fluctuates unpredictably.
- No established model exists for measuring clinician-level ED workload.
Purpose of the Study:
- To measure perceived ED workload among attending physicians.
- To assess the relationship between perceived workload and objective measures from the electronic medical record (EMR).
Main Methods:
- Study conducted in a tertiary care, academic ED from July 2020 to April 2021.
- Attending workload perceptions collected via a 5-point scale across three care areas.
- Eight EMR measures correlated with perceived workload using linear regression and ANOVA.
Main Results:
- 315 workload ratings collected; weak positive correlations found between perceived workload and inpatient admissions, ICU admissions, patient arrivals, critical care visits, CPR activations, and level 5 visits.
- Weak negative correlation observed for ED discharges.
- Stronger correlations noted in specific care areas, but no significant correlation for observation admissions or trauma activations.
Conclusions:
- EMR measures demonstrated a weak correlation with ED attending physician workload perception.
- Future research should explore factors beyond EMR data that contribute to physician workload.

Flow Sheet
Here's a closer look at the examples of flowsheets commonly used by nurses:
Graphic Sheet Documentation:
Assessment of apical radial pulse
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.
Pre-Procedural Preparation

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
Assessment of the Cardiovascular System I: Subjective Data
Initial Enquiry
Ask the patient about their primary concern and thoroughly explore all reported symptoms.
Medical History
Investigate past illnesses affecting the cardiovascular system, such as angina, anemia, rheumatic fever, congenital heart disease, stroke, thrombophlebitis, dysrhythmias, varicosities
Inquire about symptoms...
