A Human Factors Guide to Enhance EHR Usability of Critical User Interactions when Supporting Pediatric Patient Care – National Institute of Standards and Technology – June 2012 NIST

“Executive Summary

Adoption of electronic health record (EHR) systems in hospitals and physician practices is accelerating. Usability of EHRs has been identified as an important factor impacting patient safety, and recommendations for improvement have been provided. Pediatric patients have unique characteristics that translate into unique EHR usability challenges. It is not surprising, then, that the adoption of EHRs by pediatric care providers has lagged behind adoption for adult care providers. In this document, we highlight important user interactions that are especially salient for pediatric care and hence to the EHR user-centered design process. These interactions and associated usability recommendations were identified by consensus during a series of teleconferences with experts representing the disciplines of human factors engineering, usability, informatics, and pediatrics in ambulatory care and pediatric intensive care. In addition, extensive peer review was provided by experts in pediatric informatics, emergency medicine, neonatology, pediatrics, human factors engineering, usability engineering,and software development and implementation.

This report details recommendations to enhance EHR usability when supporting pediatric patient care and also identifies promising areas for EHR innovation. Finally, we illustrate unique pediatric considerations in the context of representative clinical scenarios which may be helpful for formative user-centered design approaches and summative usability evaluations.”

“Executive Summary

This document summarizes the rationale for an Electronic Health Record (EHR) Usability Protocol (EUP) that encompasses procedures for (1) expert evaluation of an EHR user interface from a clinical perspective and a human factors best practices perspective, and (2) validation studies of EHR user interfaces with representative user groups on realistic EHR tasks.

This document begins with a brief overview of the problem at hand: Why is EHR usability critical? There is a sentiment among clinical users that EHRs are harder to use than they need to be and can introduce “use error” that could have potential negative implications on patient care. This document centers on improving user performance of EHRs through system developer demonstration of application of human factors best practices and user-centered design principles.

Within this document there is a detailed description of research findings relating to the usability issues and their potential impact on patient care. These findings resulted in the development of a model for understanding usability and patient safety outcomes. As a backdrop, these findings motivate and guide the clinical aspects of the expert evaluation procedure.

Another intent of the EUP is to provide detailed systematic steps for conducting validation studies (that is, summative usability tests). The validation study procedure guides the reader to help insure that the application’s user interface is free from critical usability issues and supports error-free user interaction with the EHR. The sample forms for data collection and test scenarios provided in the appendices are guidance only; the development teams can choose other scenarios or modify these examples as necessary for their medical context.

This document presents a three-step process — that incorporates both the evaluation and validation procedures — for design evaluation and human user performance testing for an EHR, see Figure 1. This process is focused on increasing safe use of the EHR and increasing ease of use of the EHR by users. The steps are as follows:

1. Usability/Human Factors Analysis of the application during EHR user interface development,
2. Expert Review/Analysis of the EHR user interface after it is designed/developed, and
3. Testing of the EHR user interface with users.”
