Investigating the need for clinicians to use tablet computers with a newly envisioned electronic health record
Objective: The Veterans Health Administration (VHA) has deployed a large number of tablet computers in the last several years. However, little is known about how clinicians may use these devices with a newly planned Web-based electronic health record (EHR), as well as other clinical tools. The objective of this study was to understand the types of use that can be expected of tablet computers versus desktops.
Methods: Semi-structured interviews were conducted with 24 clinicians at a Veterans Health Administration (VHA) Medical Center. Results: An inductive qualitative analysis resulted in findings organized around recurrent themes of: (1) Barriers, (2) Facilitators, (3) Current Use, (4) Anticipated Use, (5) Patient Interaction, and (6) Connection.
Conclusions: Our study generated several recommendations for the use of tablet computers with new health information technology tools being developed. Continuous connectivity for the mobile device is essential to avoid interruptions and clinician frustration. Also, making a physical keyboard available as an option for the tablet was a clear desire from the clinicians. Larger tablets (e.g., regular size iPad as compared to an iPad mini) were preferred. Being able to use secure messaging tools with the tablet computer was another consistent finding. Finally, more simplicity is needed for accessing patient data on mobile devices, while balancing the important need for adequate security
Performance, workload, and usability in a multiscreen, multi-device, information-rich environment
Potential benefits of multiscreen and multiple device environments were assessed using three different computing environments. A single factor, within-subject study was conducted with 18 engineering students in a laboratory experiment. Three levels for the computing environment factor included one with a desktop computer with a single monitor (control, condition A); one with a desktop with dual monitors, as well as a single tablet computer (condition B); and one with a desktop with a single monitor, as well as two tablet computers (condition C). There was no statistically significant difference in efficiency or workload when completing scenarios for the three computing environments. However, a dual monitor desktop with a single tablet computer (B) was the ideal computing environment for the information-rich engineering problem given to participants, supported by significantly fewer errors compared to condition C and significantly higher usability ratings compared to conditions A and C. A single desktop monitor with two tablet computers (C) did not provide any advantage compared to a single desktop monitor (A)
Efficiency Strategies for Facilitating Computerized Clinical Documentation in Ambulatory Care
Most providers have experienced increased documentation demands with the use of electronic health records (EHRs). We sought to identify efficiency strategies that providers use to complete clinical documentation tasks in ambulatory care. Two observers performed ethnographic observations and interviews with 22 ambulatory care providers in a U.S. Veterans Affairs Medical Center. Observation notes and interview transcripts were coded for recurrent strategies relating to completion of the EHR progress notes. Findings included: the use of paper artifacts for handwritten notations; electronic templates for automation of certain parts of the note; use of shorthand and phrases rather than narrative writing; copying and pasting from previous EHR notes; directly entering information into the EHR note during the patient encounter; reliance on memory; and pre-populating an EHR note prior to seeing the patient. We discuss the findings in the context of distributed cognition to understand how clinical information is propagated and represented toward completion of a progress note. The study findings have important implications for improving and streamlining clinical documentation related to human factors workload management strategies
Examining the Relationship between Clinical Decision Support and Performance Measurement
In concept and practice, clinical decision support (CDS) and performance measurement represent distinct approaches to organizational change, yet these two organizational processes are interrelated. We set out to better understand how the relationship between the two is perceived, as well as how they jointly influence clinical practice. To understand the use of CDS at benchmark institutions, we conducted semistructured interviews with key managers, information technology personnel, and clinical leaders during a qualitative field study. Improved performance was frequently cited as a rationale for the use of clinical reminders. Pay-for-performance efforts also appeared to provide motivation for the use of clinical reminders. Shared performance measures were associated with shared clinical reminders. The close link between clinical reminders and performance measurement causes these tools to have many of the same implementation challenges

Evaluating a Modular Decision Support Application For Colorectal Cancer Screening
BACKGROUND:
There is a need for health information technology evaluation that goes beyond randomized controlled trials to include consideration of usability, cognition, feedback from representative users, and impact on efficiency, data quality, and clinical workflow. This article presents an evaluation illustrating one approach to this need using the Decision-Centered Design framework.
OBJECTIVE:
To evaluate, through a Decision-Centered Design framework, the ability of the Screening and Surveillance App to support primary care clinicians in tracking and managing colorectal cancer testing.
METHODS:
We leveraged two evaluation formats, online and in-person, to obtain feedback from a range primary care clinicians and obtain comparative data. Both the online and in-person evaluations used mock patient data to simulate challenging patient scenarios. Primary care clinicians responded to a series of colorectal cancer-related questions about each patient and made recommendations for screening. We collected data on performance, perceived workload, and usability. Key elements of Decision-Centered Design include evaluation in the context of realistic, challenging scenarios and measures designed to explore impact on cognitive performance.
RESULTS:
Comparison of means revealed increases in accuracy, efficiency, and usability and decreases in perceived mental effort and workload when using the Screening and Surveillance App.
CONCLUSION:
The results speak to the benefits of using the Decision-Centered Design approach in the analysis, design, and evaluation of Health Information Technology. Furthermore, the Screening and Surveillance App shows promise for filling decision support gaps in current electronic health records
Paper Persistence and Computer-based Workarounds with the Electronic Health Record in Primary Care
With the United States national goal and incentive program to transition from paper to electronic health records (EHRs), healthcare organizations are increasingly implementing EHRs and other related health information technology (IT). However, in institutions which have long adopted these computerized systems, such as the Veterans Health Administration, healthcare workers continue to rely on paper to complete their work. Furthermore, insufficient EHR design also results in computer-based workarounds. Using direct observation with opportunistic interviewing, we investigated the use of paper- and computer-based workarounds to the EHR with a multi-site study of 54 healthcare workers, including primary care providers, nurses, and other healthcare staff. Our analysis revealed several paper- and computer-based workarounds to the VAâs EHR. These workarounds, including clinician-designed information tools, provide evidence for how to enhance the design of the EHR to better support the needs of clinicians
Ambulatory Clinic Exam Room Design with respect to Computing Devices: A Laboratory Simulation Study
BackgroundâChallenges persist regarding how to integrate computing effectively into the exam room, while maintaining patient-centered care. PurposeâOur objective was to evaluate a new exam room design with respect to the computing layout, which included a wall-mounted monitor for ease of (re)-positioning. MethodsâIn a lab-based experiment, 28 providers used prototypes of the new and older âlegacyâ outpatient exam room layouts in a within-subject comparison using simulated patient encounters. We measured efficiency, errors, workload, patient-centeredness (proportion of time the provider was focused on the patient), amount of screen sharing with the patient, workflow integration, and provider situation awareness. ResultsâThere were no statistically significant differences between the exam room layouts for efficiency, errors, or time spent focused on the patient. However, when using the new layout providers spent 75% more time in screen sharing activities with the patient, had 31% lower workload, and gave higher ratings for situation awareness (14%) and workflow integration (17%). ConclusionsâProviders seemed to be unwilling to compromise their focus on the patient when the computer was in a fixed position in the corner of the room and, as a result, experienced greater workload, lower situation awareness, and poorer workflow integration when using the old âlegacyâ layout. A thoughtful design of the exam room with respect to the computing may positively impact providersâ workload, situation awareness, time spent in screen sharing activities, and workflow integration
Persuasive health educational materials for colorectal cancer screening
This paper describes an effort to design and evaluate persuasive educational materials for colorectal cancer (CRC) screening. Although CRC screening is highly effective, screening rates in the US remain low. Educational materials represent one strategy for educating patients about screening options and increasing openness to screening. We developed a one-page brochure, leveraging factual information from the Centers for Disease Control and Prevention (CDC) and national guidelines, and strategies for persuasion from the human factors and behavioral economics literatures. We evaluated the resulting brochure with adults over the age of 50. Findings suggest that the educational brochure increases knowledge of CRC and screening options, and increases openness to screening. Furthermore, no significant difference was found between the new one-page brochure and an existing multi-page Screen for Life brochure recommended by the CDC. We interpret these findings as indication that the more practical and potentially less intimidating one-page brochure is as effective as the existing multi-page Screen for Life brochure
Clinician Perspectives on Unmet Needs for Mobile Technology Among Hospitalists:Workflow Analysis Based on Semistructured Interviews
Background: The hospitalist workday is cognitively demanding and dominated by activities away from patientsâ bedsides. Although mobile technologies are offered as solutions, clinicians report lower expectations of mobile technology after actual use.
Objective: The purpose of this study is to better understand opportunities for integrating mobile technology and apps into hospitalistsâ workflows. We aim to identify difficult tasks and contextual factors that introduce inefficiencies and characterize hospitalistsâ perspectives on mobile technology and apps.
Methods: We conducted a workflow analysis based on semistructured interviews. At a Midwestern US medical center, we recruited physicians and nurse practitioners from hospitalist and inpatient teaching teams and internal medicine residents. Interviews focused on tasks perceived as frequent, redundant, and difficult. Additionally, participants were asked to describe opportunities for mobile technology interventions. We analyzed contributing factors, impacted workflows, and mobile app ideas.
Results: Over 3 months, we interviewed 12 hospitalists. Participants collectively identified chart reviews, orders, and documentation as the most frequent, redundant, and difficult tasks. Based on those tasks, the intake, discharge, and rounding workflows were characterized as difficult and inefficient. The difficulty was associated with a lack of access to electronic health records at the bedside. Contributing factors for inefficiencies were poor usability and inconsistent availability of health information technology combined with organizational policies. Participants thought mobile apps designed to improve team communications would be most beneficial. Based on our analysis, mobile apps focused on data entry and presentation supporting specific tasks should also be prioritized.
Conclusions: Based on our results, there are prioritized opportunities for mobile technology to decrease difficulty and increase the efficiency of hospitalistsâworkflows. Mobile technology and task-specific mobile apps with enhanced usability could decrease overreliance on hospitalistsâ memory and fragmentation of clinical tasks across locations. This study informs the design and implementation processes of future health information technologies to improve continuity in hospital-based medicine.This work was supported by a pilot grant (PPO 15-401; AS) and a Center of Innovation grant (CIN 13-416, M Weiner), both from the United States Department of Veterans Affairs Health Services Research and Development.
