EHR Use in Inpatient Physicians: Patterns and Predictors.

Electronic health record (EHR) systems have become integral to hospital-based care, with studies showing physicians spending significant time interfacing with these systems. While EHR interactions are necessary for patient care, understanding usage patterns can identify opportunities for system optimization and workflow improvement. Previous studies have focused on outpatient settings, making this study among the first to comprehensively analyze inpatient EHR interaction patterns.This study aims to characterize EHR utilization patterns among inpatient physicians and analyze how these patterns vary by physician characteristics, including gender, specialty, and years of experience. This analysis aims to identify opportunities for targeted EHR optimization and workflow enhancement strategies.We analyzed nine key EHR interaction metrics from Epic Signal across 1,787 inpatient physicians during February 2024. Metrics included time spent in various EHR activities, patient volume, secure message usage, and specific feature utilization. Multivariate regression models were then generated for each outcome metric.Female physicians spent more time per patient in the EHR (21.74 vs. 15.62 minutes, p < 0.001) and utilized secure messaging features more frequently (messages sent: 0.82 vs. 0.06 per day, p < 0.001). Internal Medicine/Pediatrics demonstrated higher EHR interaction times across multiple metrics compared to Surgical Specialists, even after adjusting for patient load (51.93 vs. 8.37 minutes per day, p < 0.001). Years since graduation showed significant negative correlations with most EHR interaction metrics (r = -0.11 to -0.27, p < 0.001).This analysis reveals significant variation in EHR utilization patterns across physician demographics and specialties. These findings can inform targeted interventions to optimize EHR workflows and support efficient system usage while maintaining documentation quality and patient care standards.
