Environmental cleaning and disinfection in the operating room: a systematic scoping review through a human factors and systems engineering lens.

OBJECTIVE: To synthesize evidence and identify gaps in the literature on environmental cleaning and disinfection in the operating room based on a human factors and systems engineering approach guided by the Systems Engineering Initiative for Patient Safety (SEIPS) model. DESIGN: A systematic scoping review. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched 4 databases (ie, PubMed, EMBASE, OVID, CINAHL) for empirical studies on operating-room cleaning and disinfection. Studies were categorized based on their objectives and designs and were coded using the SEIPS model. The quality of randomized controlled trials and quasi-experimental studies with a nonequivalent groups design was assessed using version 2 of the Cochrane risk-of-bias tool for randomized trials. RESULTS: In total, 40 studies were reviewed and categorized into 3 groups: observational studies examining the effectiveness of operating-room cleaning and disinfections (11 studies), observational study assessing compliance with operating-room cleaning and disinfection (1 study), and interventional studies to improve operating-room cleaning and disinfection (28 studies). The SEIPS-based analysis only identified 3 observational studies examining individual work-system components influencing the effectiveness of operating-room cleaning and disinfection. Furthermore, most interventional studies addressed single work-system components, including tools and technologies (20 studies), tasks (3 studies), and organization (3 studies). Only 2 studies implemented interventions targeting multiple work-system components. CONCLUSIONS: The existing literature shows suboptimal compliance and inconsistent effectiveness of operating-room cleaning and disinfection. Improvement efforts have been largely focused on cleaning and disinfection tools and technologies and staff monitoring and training. Future research is needed (1) to systematically examine work-system factors influencing operating-room cleaning and disinfection and (2) to redesign the entire work system to optimize operating-room cleaning and disinfection.

'Strangers in a strange land': Understanding professional challenges for human factors/ergonomics and healthcare.

Human Factors and ergonomics (HFE) expertise continues to have difficulty integrating its experts into healthcare. This persistent disconnect is compounded by unique aspects of healthcare as an institution, industry and work system. Clinically-embedded HFE practitioners, a new HFE sub-specialty, are a conduit for addressing substantive mismatches between the two domains. Greater HFE penetration will require a fundamental change in stance for both domains, however, the burden will lie with HFE to be the more adaptive of the two. Learning more about the in situ work of this sub-specialty will provide insights for more nuanced approaches to bridging domain specific mismatches and obstacles.

Design and Evaluation of an Integrated, Patient-Focused Electronic Health Record Display for Emergency Medicine.

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 effectiveness. In particular, there is a need to support clinicians to communicate and maintain awareness of a patient's health status, and progress through the ED plan of care. OBJECTIVE: This study used work-centered usability methods to evaluate an integrated patient-focused status display designed to support ED clinicians' communication and situation awareness regarding a patient's health status and progress through their ED plan of care. The display design was informed by previous studies we conducted examining the information and cognitive support requirements of ED providers and nurses. METHODS: ED nurse and provider participants were presented various scenarios requiring patient-prioritization and care-planning tasks to be performed using the prototype display. Participants rated the display in terms of its cognitive support, usability, and usefulness. Participants' performance on the various tasks, and their feedback on the display design and utility, was analyzed. RESULTS: Participants provided ratings for usability and usefulness for the display sections using a work-centered usability questionnaire-mean scores for nurses and providers were 7.56 and 6.6 (1 being lowest and 9 being highest), respectively. General usability scores, based on the System Usability Scale tool, were rated as acceptable or marginally acceptable. Similarly, participants also rated the display highly in terms of support for specific cognitive objectives. CONCLUSION: A novel patient-focused status display for emergency medicine was evaluated via a simulation-based study in terms of work-centered usability and usefulness. Participants' subjective ratings of usability, usefulness, and support for cognitive objectives were encouraging. These findings, including participants' qualitative feedback, provided insights for improving the design of the display.

Usability evaluation of an emergency department information system prototype designed using cognitive systems engineering techniques.

This article presents an evaluation of novel display concepts for an emergency department information system (EDIS) designed using cognitive systems engineering methods. EDISs assist emergency medicine staff with tracking patient care and ED resource allocation. Participants performed patient planning and orientation tasks using the EDIS displays and rated the display's ability to support various cognitive performance objectives along with the usability, usefulness, and predicted frequency of use for 18 system components. Mean ratings were positive for cognitive performance support objectives, usability, usefulness, and frequency of use, demonstrating the successful application of design methods to create useful and usable EDIS concepts that provide cognitive support for emergency medicine staff. Nurse and provider roles had significantly different perceptions of the usability and usefulness of certain EDIS components, suggesting that they have different information needs while working.

Communication in the Electronic Age: an Analysis of Face-to-Face Physician-Nurse Communication in the Emergency Department.

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 communication) and content of nurse to physician conversations. Eighteen emergency nurses and physicians (nine each) were observed for a total of 36 h. Two hundred and fifty-five unique communication events were recorded across three emergency departments spread evenly across day, evening, and night shifts. A qualitative analysis of communication event content revealed 5 types of communication and 13 content themes. Content themes covered a broad range of topics including exchange of patient health information, management of the ED, and coordination of orders. Physician participants experienced significantly more communication events than nurse participants, while nurses initiated significantly more communication events than physicians. Most of the communication events occurred at the physician workstation followed by patient treatment areas. This study describes nature of verbal nurse to physician communication in the ED. Direct communication is still used to communicate important information, such as information about patients' status, in EDs with established electronic health records. Our results provide an overview of information exchanged in the ED which can serve as a basis for designing improved information support systems.

Development of a simulation environment to study emergency department information technology.

INTRODUCTION: This article presents a simulation architecture for a patient tracking system simulator to study caregiver performance in emergency departments (EDs). The architecture integrates discrete event simulation modeling with clinical patient information. Evaluation components for electronic patient tracking system displays are also described. METHODS: A simulation of an ED electronic whiteboard was developed to study situation awareness metrics. Dynamic process data from an actual ED was used to generate simulation parameters including patient arrivals at various hours, distribution of severities, times required to treat the ED patients, and ancillary turnaround times (laboratory and radiology). A team of industrial engineers and ED physicians contributed demographic and clinical information for simulator patients. ED simulation parameters were combined with clinical information resulting in an event timeline database. Event timelines were used to populate a front-end patient-tracking system display simulation. RESULTS: The resulting patient-tracking system display simulation consists of underlying software, desktop and large-screen displays, a phone call/pager system, and typical tasks that enhance the realism of the simulation experience. The system can evaluate the impact of display parameters and ED operations on user performance. CONCLUSIONS: Modular design of the patient-tracking system display simulation helps adaptation for different studies to support various interface features and interaction types. The methodology described in this work exploits the benefits of discrete event simulation to iteratively design and test technologies such as electronic patient tracking systems and allows assessment of human performance measures.

An overlooked alliance: using human factors engineering to reduce patient harm.

BACKGROUND: Although human factors engineering (HFE) is considered only in relationship to the design of medical devices or information systems technology, human factors issues arise in many aspects of work in health care organizations. HFE ANALYSIS: In one scenario, the resuscitation stretcher would not pass through the ED door closest to radiology. Many clinical work spaces were never formally designed for the work currently being performed in them; instead, they were adapted from existing space originally designed for a different use. In a second scenario, infusion pump malfunction was not apparent. The patient experienced a near miss secondary to poor design; users thought that the infusion pump had been turned off when it was not. RECOMMENDATIONS: Health care can significantly benefit from the incorporation of HFE into the workplace. Introductory classes in medical and nursing schools on HFE will assist students in detecting HFE-related issues, making them less likely to suffer with them or overlook them once in clinical practice. More extensive training for patient safety and risk managers, that is, at a minimum, a certificate-level course from an HFE program, would enhance case and root cause analyses since these issues are rarely factored in. CONCLUSION: Collaboration with HFE experts and use of HFE principles may not make health care fool-proof, but it will make it less dependent on improvisation and ingenuity to protect patients from the system's vulnerabilities.

Human factors and ergonomics in the emergency department.

Although health care rapidly adopts technologic advances from other fields, it has been slow to incorporate well-established principles from human factors engineering into the health care workplace. This article demonstrates some of those principles by analyzing an all too routine clinical event from a human factors point of view. Review of this case and ergonomic principles leads us to conclude that the routine application of human factors engineering principles could improve patient safety and would likely improve system efficiency as well.
