Objectives: This study explores nurses’ use of bar code medication administration (BCMA) technology from a human factors viewpoint. The BCMA technology consists of a medication network server and handheld devices that connect to medication administration record data through wireless radiofrequency link. Methods: A total of 62 observations of medication(More)
Effective design of health information technology (HIT) for patient-centered care requires consideration of workflow from the patient's perspective, termed 'patient-oriented workflow.' This approach organizes the building blocks of work around the patients who are moving through the care system. Patient-oriented workflow complements the more familiar(More)
OBJECTIVES We examine the following: (1) the appropriateness of using a data quality (DQ) framework developed for relational databases as a data-cleaning tool for a data set extracted from two EPIC databases, and (2) the differences in statistical parameter estimates on a data set cleaned with the DQ framework and data set not cleaned with the DQ framework.(More)
BACKGROUND Health information exchange (HIE) allows clinicians to access patient level health care information. HIE can potentially improve patient care in emergency departments. METHODS We present a selected piece of evaluation of an HIE implementation in three Midwestern emergency departments. Data were collected through over 210 hours of direct(More)
In this paper, we describe the use of observational methods to assess the interaction between nurses and medication administration technologies. The observations were conducted to examine the use of point-of-care bar code technology and preand post-implementation of intravenous (IV) pumps with medication delivery software to prevent programming errors(More)
Workflow is widely used in system design, process re-engineering and information science and has recently been receiving much attention in health care. However, the meaning of workflow has been defined very implicitly for health care settings. The objective of this study is to explore the meaning of workflow by using a structural concept analysis method.(More)
BACKGROUND Studying workflow is a critical step in designing, implementing and evaluating informatics interventions in complex sociotechnical settings, such as hospital emergency departments (EDs). Known approaches to studying workflow in clinical settings attend to the activities of individual clinicians, thus being inadequate to characterize patient care(More)
This paper describes the development of the observation methodologies that we have developed to examine the interactions between nurses and two medication administration technologies: point-of-care bar code technology and Smart IV pump technology. Various issues related to the observation methodologies are discussed: procedure for conducting the(More)
OBJECTIVE The purpose of this study was to describe a workflow analysis approach and apply it in emergency departments (EDs) using data extracted from the electronic health record (EHR) system. MATERIALS AND METHODS We used data that were obtained during 2013 from the ED of a children's hospital and its four satellite EDs. Workflow-related data were(More)
PURPOSE The needs of complex patients with chronic conditions can be unpredictable and can strain resources. Exploring how tasks vary for different patients, particularly those with complex needs, can yield insights about designing better processes in healthcare. The purpose of this paper is to explore the tasks required to manage complex patients in an(More)
