Objectives: Medication information is frequently communicated via free-text computerized provider order entry (CPOE) orders in electronic health records. When such information is transmitted separately from a structured CPOE medication order, there is a significant risk of medication error. Although prior studies have described the frequency of us...

Objective The aim of this study was to investigate (1) why ordering clinicians use free-text orders to communicate medication information; (2) what risks physicians and nurses perceive when free-text orders are used for communicating medication information; and (3) how electronic health records (EHRs) could be improved to encourage the safe communi...

Introduction Understanding and managing clinician workload is important for clinician (nurses, physicians and advanced practice providers) occupational health as well as patient safety. Efforts have been made on developing strategies for managing clinician workload by improving patient assignment. The goal of the current study is to use electronic...

Communication for non-medication order (CNMO) is a type of free text communication order providers use for asynchronous communication about patient care. The objective of this study was to understand the extent to which non-medication orders are being used for medication-related communication. We analyzed a sample of 26 524 CNMOs placed in 6 hospit...

Background: The use of new technology like virtual reality, e-learning, and serious gaming can offer novel, more accessible options that have been demonstrated to improve learning outcomes. Objective: The aim of this study was to compare the educational effectiveness of serious game-based simulation training to traditional mannequin-based simula...

BACKGROUND The use of new technology like virtual reality, e-learning, and serious gaming can offer novel, more accessible options that have been demonstrated to improve learning outcomes. OBJECTIVE The aim of this study was to compare the educational effectiveness of serious game–based simulation training to traditional mannequin-based simulation...

Background The current state of scientific knowledge regarding communication between emergency medicine (EM) providers indicates that communication is critical to safe and effective patient care. Objectives In this study, we identified communication needs of EM nurses and physicians; in particular, what information should be conveyed, when, how, a...

This research is a first stage in developing a method for modeling the clinician workload associated with an emergency medicine patient in order to display workload for purposes of managing clinician workload and emergency department (ED) flow. We proposed a multi-stage approach of predicting patient-related drivers of clinician’s workload in the e...

Background Hospital emergency departments (EDs) are dynamic environments, involving coordination and shared decision making by staff who care for multiple patients simultaneously. While computerized information systems have been widely adopted in such clinical environments, serious issues have been raised related to their usability and effectivenes...

Introduction: Electronic health record (EHR) downtime is any period during which the EHR system is fully or partially unavailable. These periods are operationally disruptive and pose risks to patients. EHR downtime has not sufficiently been studied in the literature, and most hospitals are not adequately prepared. Objective: The objective of this s...

OCCUPATIONAL APPLICATION Understanding and managing clinician workload is important both for the occupational health of clinicians and for the safety of patients. This study describes the integration of a new display concept for visualizing emergency medicine physician and nurse workload into a live electronic health record along with an investigat...

Objectives: Emergency Department crowding is an increasing problem, leading to treatment delays and higher risk of mortality. Our institution recently implemented a telemedicine physician intake ("tele-intake") process as a mitigating front-end strategy. Previous studies have focused on ED throughput metrics such as door to disposition; our work a...

We describe the patterns and content of nurse to physician verbal conversations in three emergency departments (EDs) with electronic health records. Emergency medicine physicians and nurses were observed for 2 h periods. Researchers used paper notes to document the characteristics (e.g., partners involved, location of communication, who initiated c...

Human factors research often involves the use of domain experts as research subjects, and in studies that target healthcare providers as participants, recruitment can be challenging. Physicians are particularly difficult to recruit given their time constraints and relatively high threshold for financial incentive. Understanding the motivation for p...

Stationary eye-tracking technology has been used extensively in human-computer interaction to both understand how humans interact with computers and as an interaction mechanism. Mobile eye-tracking technology is becoming more prevalent, yet the analysis and annotation of mobile eye-tracking data remains challenging. We present a novel human-in-the-...

Importance and objectives: As health information technologies become more prevalent in physician workflow, it is increasingly important to understand how physicians are using and interacting with these systems. This includes understanding how physicians search for information presented through health information technology systems. Eye tracking te...

Patient Safety Event (PSE) reporting systems are widely utilized by healthcare providers across the country as a method for gathering information from front-line healthcare providers about patient safety. Automated processes that utilize natural language processing (NLP) techniques have been developed and applied to analyze these reports. The objec...
