definition of usability in health information systems

Data management flowchart. KL B The MEDLINE search retrieved an equal number of subjective evaluations (eg, self-report questionnaire) and objective evaluations (eg, log file analysis, cognitive walkthrough, and chart review). An evaluation using a Wizard-of-Oz experimental paradigm, Participatory Design: Principles and Practices. et al. . Abran Software needs vary depending on dozens of physician disciplines, which often need different software interface design. Shahar .

Lehto ACM. Khelifi They collect data and compile it in a way that can be used to make healthcare decisions. . WW . The stakeholders in the healthcare UX environment are a diverse group, including both a wide range of people and an equally diverse world of devices and systems, all of whom interact with the EHR in some way. In virtually all EHR implementations there are design implications to the localization of the system that can significantly impact usability. System validation was done mainly through examining sensitivity and specificity or the ROC curve, and was commonly found in computer-assisted diagnosis systems, such as computer-assisted image interpretation systems, but rarely in other documentation systems. Stage 5 comprised studies of health IT implemented in a fully supported environment; study designs included experimental or quasi-experimental designs and control groups in multiple sites including before and after implementation, or with postimplementation evaluation only. Friedman Animal and non-English studies and literature published before 2003 were excluded, along with non-studies, such as reviews, commentaries, and letters. Kushniruk of the usability of a health information system. RH . Unfortunately, because EHRs often require complex technical integration, design and usability are often an afterthought and fail to incorporate a robust user-centered design process or full scale usability testing. Sittig Rahimi and Vimarlund10 reviewed general methods used to evaluate health IT. Task/expectation complexity, user variances, and organizational support are factors that influence the use of the system, but are not problems of the system itself, and need to be differentiated from system-related issues.

Halloran OA D A comparison between the five stages of the Stead framework and Friedman and Wyatt's nine generic study types11 is shown in table 1; both point out the importance of iterative evaluation to continuously assess and refine system design for ultimate system usability. . But, today’s focus on meaningful use of electronic health records represents an unprecedented opportunity to refine the design process in this domain and bring a fundamental understanding of the impact of usability back into the design and development of EHRs. W Johnson With both development experience and technological capacity, these companies work across disparate systems—from radiology images and laboratory results to claims and billing—and they offer a unique perspective on design and implementation, at least for specific use cases. KB Vatne For a designer, this means that understanding not just the different clinical roles, but also the workflow and the (often hierarchical) work system are important elements of usability. The research was supported by the Center for Evidence-based Practice in the Underserved (P30NR010677). Lanway Stead Roumina Davis Proceedings of the Latin American conference on Human-computer interaction. AW An evaluation of perceived usability based on the level of task/expectations would then be able to reveal the system usability at each level of task/expectations. S The aspect of evaluation that deals with the interaction between user and data system is called evaluation of usability ( 11 ). Ash There is a need to update and build upon the valuable knowledge provided by these earlier reviews and to more explicitly consider user–task–system–environment interaction.12,13 Therefore, the purposes of this paper are to review and categorize commonly used health IT usability study methods using an integrated usability specification and evaluation framework and to provide practical guidance on health IT usability evaluation. Fourth, our review focused on identifying methods and scales used, but did not evaluate best methods or scales for usability evaluation because the selection of methods and scales also depends on the type of health IT, evaluation goals, and other variables. . This presentation will describe methods for assessing the usability of information systems and for evaluating the impact of advanced health care information systems on reasoning and decision making. EH G L . Coia Since 2000, she has created, developed, and assessed electronic health information tools. Health Information Technology Usability Evaluation: Methods, Models, and Measures Po-Yin Yen Submitted in partial fulfillment of the requirements for Lee To be successful, UX designers need to bring both an understanding of good practice as well as a willingness to apply design guidelines to specific problems encountered in implementation. This is consistent with a previous literature review of evaluation designs for health information systems.10 Most theoretical frameworks used were adapted from HCI, information system management, or cognitive behavioral science. . Level 3 aims to incorporate environmental factors to identify work processes and system impacts in real settings. For information management (eg, information needs), b. Reviews, commentaries, editorials, and case studies were only included for background information or discussion, not for the review because of the methodological focus of the review. Marcial, L. (2014). Stage 1 is a needs assessment for system development. Picture archiving and communication system, 4. A system may be useful for achieving a specific task, but may not be beneficial to users' general work life. Researchers use these theories/models to support their study rationales. Usability methods need to consider the entire socio-technical system, not just the individual user. et al. At level 3, we can minimize user variance by user training and providing sufficient organizational support. . Halbesleben Most stages have more than one evaluation type because iterative evaluation is needed to test multiple interactions. ROC, Receiver operating characteristic; SDLC, system development life cycle. RM Therefore, a total of 310 publications was identified as stage 2 system validation studies. Even though identifying system features, functions, and interfaces from the user perspective is essential for the design of usable system, the perspective is frequently lacking. For example, we first expect the system to be able to perform a task (stage 1). The goal of stage 2 is system validation. Among these studies, the most frequently used questionnaires were the questionnaire for user interaction satisfaction, the modified technology acceptance model questionnaire, and the IBM usability questionnaire.50–53 However, more than half of the studies used study-generated questionnaires that were not previously validated. Explication of the qualitative approach is important to determine study rigor with regard to criteria such as credibility, trust worthiness, and auditability. Objective measures that researchers used at stage 3 included system validity (eg, accuracy and completeness) and efficiency (eg, speed and learnability). Theoretical and methodological aspects of 319 studies were extracted in greater detail and studies that focused on system validation (SDLC stage 2) were not assessed further. Related goals include actively engaging patients and their families in quality care, improving care coordination, and informing population and public health. A Dahlback Information Systems Training. In this section we summarize methodological issues in existing studies and describe a stratified view of health IT usability evaluation. . JP In the last column, evaluation goals represent the expectations for each evaluation type. Some guidelines, like those outlined by the NCCD apply broadly to all implementations of an EHR. JRB It's also no good if the system can hypothetically do what you want, but you can't make it happen because the user interface is too difficult. The use of new technologies like netbooks, tablets, mini-tablets, smartphones, and connected eyewear in the clinical encounter has only increased the likelihood that your primary care doctor is a key actor in selecting and maintaining your EHR. Health IT types were based on the classification of Gremy and Degoulet25 and three types of decision support functions described by Musen et al.26 We organized studies based on the usability specification and evaluation framework (table 2). Therefore, the total number of studies in each evaluation stage does not match the total number of included studies. Avoid disruptions – e.g., forced logins/pop-ups. J Ammenwerth Both authors agreed upon the study extraction and categorization. D . This approach may potentially simplify the identification of usability problems through focusing on a specific interaction. . Mihailidis Achieving excellent usability in EHRs is daunting, given the information needs of administrative, financial and clinician groups. C Muller-Staub Patel Many health IT usability studies have been conducted to explore usability requirements, discover usability problems, and design solutions. Inspired by Bennett and Shackel's usability model, the health IT usability specification and evaluation framework (table 2), which we adapted and applied in our review, provides a categorization of study approaches by evaluation types. T Titles and abstracts were first reviewed for inclusion. However, challenges include: the complexity of the evaluation object: evaluation usually involves not only hardware, but also the information process in a given environment; the complexity of an evaluation project: evaluation is usually based on various research questions from a sociological, organizational, technical or clinical point of view; and the motivation for evaluation: evaluation can only be conducted with sufficient funds and participants.7 Various experts have conducted reviews that identified knowledge gaps and subsequently suggested possible solutions. This indicates a need for stratification of evaluation types; therefore, we defined goals based on the evaluation type being measured. The SDLC provides a commonly accepted guide for system development and evaluation. One study used work sampling to identify nurses' needs for the development of an electronic information gathering and dissemination system.30, Methods used by researchers in this review to inform health IT interface designs included colored sticky notes, focus groups,35 cognitive work analysis,36 and card sorting.37 We categorized system redesign as stage 1. Two additional methods59,60 that were not within our original search scope, but which were subsequently discovered are also included because of their potential value to health IT usability evaluation. D Saleem . Horsky In stage 1, the evaluation type starts from the simplest level, ‘type 0: task’, which aims to understand the task itself, and another level, ‘type 1: user–task’ interaction, to discover essential requirements for system design, such as information flow, system functionality, user interface, etc. . Fitzhenry S F . Therefore, usability evaluation questions are: ‘What is the user, task, system, and environment interaction performance in terms of output quality, speed, accuracy, and completeness?’; ‘Is the user satisfied with the way the system helps perform a task in the real setting?’; and ‘Does the system change workflow effectiveness or efficiency?’, Twelve studies used observation, log files, and/or chart review to assess interaction performance, such as accuracy, time, completeness, and general workflow. Because of its complexity, inherent unpredictability, and often erratic nature, the use of ICT in the healthcare system requires unique attention to context. In software engineering, usability is the degree to which a software can be used by specified consumers to achieve quantified objectives with effectiveness, efficiency, and satisfaction in a quantified context of use.. et al. Definition of Utility = whether it provides the features you need. The predominant type of health IT that we evaluated was decision support systems or had decision support features; computer-based provider order entry within hospital information systems were also well studied. More often than not, this means that EHR implementation, regardless of the relative robustness of a vendor system, is highly customized for a given environment or context. However, the use of ICT to deliver safe and sustainable healthcare systems has been described as a “wicked problem,” referring to the complex web of stakeholders, systems, and legislative parameters involved. Based on the findings, a three-level stratified view of health IT usability evaluation is proposed and methodological guidance is offered based upon the type of interaction that is of primary interest in the evaluation. The research questions for the review are: based on SDLC stages, when do health IT usability studies usually occur? M HA Haynes et al. R Kushniruk Often called clinical data warehouses, these systems, often database driven, support a wide variety of research and surveillance activities aimed at improving quality and require their own interface guidelines. Nielsen MA . JC Peute However, this was the first review of health IT studies using an integrated usability specification and evaluation framework, and it provides an inventory of evaluation frameworks and methods and practical guidance for their application. Criteria for study categorization based on the SDLC stages. B Health information systems consist of six key components, including: 1. McKeown Theoretical frameworks/models are essential to research studies, suggesting rationale for hypothesized relationships and providing the basis for verification. Studies that fit the exclusion criteria or that had insufficient methods information for data extraction were subsequently excluded resulting in the retention of 346 studies. Macias G Lewis Studies that focused on HCI in the laboratory setting, such as outcome quality, user perception, and user performance, were categorized as stage 3. Define user-centered design. Lavin Kaufman and colleagues6 further illustrated its use as an evaluation framework for health information system design, development, and implementation. One group of products was developed at the grass roots by hospital or medical organizations with vision and technical capabilities aiming to meet their own needs. ES ... we have applied definitions of usability from the HCI field when describing the usability of clinical ICT systems from the viewpoint of different end-user groups with the aim of increasing the understanding of contextual aspects unique in clinical contexts. EHRs require data across a group of integrated, previously stand-alone, systems. In the stratified view, level 1 targets system specification to understand user–task interaction for system development, which is usually conducted in SDLC stage 1. . One study54 used workflow analysis to evaluate the work process before and after health IT was implemented.33. The most common study design was a quasi-experimental study design using one group with pretest and posttest comparison, or with only posttest assessment. Lee . . V Shiffman et al. Detmer . These are often the result of ad hoc configurations or accommodations focused on the integration of existing systems and any limitations that this process might surface. Search terms and detailed strategy are available as a data supplement online only. For focusing attention (eg, reminder/alert system), c. For providing patient-specific recommendations, Utilization, patient outcomes, guideline adherence, medication errors, Utilization, patient outcomes, guideline adherence, medication errors, accuracy, document quality, cost-effectiveness, General system development/design framework, Copyright © 2020 American Medical Informatics Association. However, it can be difficult to determine the efficiency of a healthcare information system, but the … There is no doubt that the usability of health IT is critical to achieving its promise in improving health care and the health of the public. et al. Jr This is likely due to the system's decision support role. Despite the proliferation of a range of information systems, there are continued reports of systems that have failed to be effectively adopted by end users and a lack of usability has been implicated in many of these cases.
