Behavioral Phenotypes in Electronic Health Record Use by Primary Care Providers: a Cluster Analysis.

Background The use of electronic health record (EHR) systems varies among primary care providers (PCPs). However, little is known about how numerous different EHR use behaviors, such as time spent and collaboration in the EHR, cluster together. Prior efforts to quantify characteristics of PCPs using EHRs have generally focused on single behaviors.Objective To identify patterns of EHR use among PCPs using a data-driven clustering approach.Design Cross-sectional study analyzing EHR data from the 2021 calendar year.Participants Primary care providers practicing in a large Massachusetts healthcare system.Approach PCPs were assigned to groups based on patterns of EHR use across 30 monthly variables from EHR data using a k-means clustering approach. We used Elbow, Silhouette, and Gap statistic methods to determine the number of clusters. Cluster characteristics were analyzed descriptively.Key Results In total, 163 PCPs were included; 103 (63%) PCPs were female, and 113 (69%) were White. Three distinct clusters of PCPs were identified, named based on the EHR characteristics that differed most across the clusters: (1) "High-engagement users": 38% of PCPs; (2) "Low-engagement users": 42%; and (3) "Moderate and selective users": 20%.Conclusions This study identified three distinct patterns of EHR use among PCPs, characterized by different levels of engagement with EHR functionality and time spent in the EHR. Further studies are needed to explore how EHR-based interventions could be tailored to different provider workflow styles.
