Handling Anticipated Exceptions In Clinical Care: Investigating The Benefits And Consequences Of Providing “Exit Strategies” In Computerized Clinical Information Systems, Kai Zheng, David Hanauer, Rema Padman, Michael Johnson, Anwar Hussain, Wen Ye, Xiaomu Zhou, Herbert Diamond

Unpredictable yet frequently occurring exception situations pervade clinical care. Handling them properly often requires aberrant actions temporarily departing from normal practice. In this study, the authors investigated several exception-handling procedures provided in an electronic health records system for facilitating clinical documentation, which the authors refer to as ‘data entry exit strategies.’ Through a longitudinal analysis of computer-recorded usage data, the authors found that (1) utilization of the exit strategies was not affected by postimplementation system maturity or patient visit volume, suggesting clinicians' needs to ‘exit’ unwanted situations are persistent; and (2) clinician type and gender are strong predictors of exit-strategy ...


Social Networks And Physician Adoption Of Electronic Health Records: Insights From An Empirical Study, Kai Zheng, Rema Padman, David Krackhart, Michael Johnson, Herbert Diamond Dec 2009

Social Networks And Physician Adoption Of Electronic Health Records: Insights From An Empirical Study, Kai Zheng, Rema Padman, David Krackhart, Michael Johnson, Herbert Diamond

Objective: To study how social interactions influence physician adoption of an electronic health records (EHR) system. Design: A social network survey was used to delineate the structure of social interactions among 40 residents and 15 attending physicians in an ambulatory primary care practice. Social network analysis was then applied to relate the interaction structures to individual physicians’ utilization rates of an EHR system. Measurements: The social network survey assessed three distinct types of interaction structures: professional network based on consultation on patient care-related matters; friendship network based on personal intimacy; and perceived influence network based on a person’s perception ...


An Interface-Driven Analysis Of User Behavior Of An Electronic Health Records System, Kai Zheng, Rema Padman, Michael Johnson, Herbert Diamond Dec 2008

An Interface-Driven Analysis Of User Behavior Of An Electronic Health Records System, Kai Zheng, Rema Padman, Michael Johnson, Herbert Diamond

Michael P. Johnson

Objectives: This study sought to investigate user interactions with an electronic health records (EHR) system by uncovering hidden navigational patterns in the EHR usage data automatically recorded as clinicians navigated through the system’s software user interface (UI) to perform different clinical tasks. Design: A homegrown EHR was adapted to allow real-time capture of comprehensive UI interaction events. These events, constituting time-stamped event sequences, were used to replay how the EHR was used in actual patient care settings. The study site is an ambulatory primary care clinic at an urban teaching hospital. Internal medicine residents were the primary EHR users ...
