Development and Evaluation of I-PASS-to-PICU: A Standard Electronic Template to Improve Referral Communication for Interfacility Transfers to the Pediatric ICU.

BACKGROUND: Miscommunication during interfacility handoffs to a higher level of care can harm critically ill children. Adapting evidence-based handoff interventions to interfacility referral communication may prevent adverse events. The objective of this project was to develop and evaluate a standard electronic referral template (I-PASS-to-PICU) to improve communication for interfacility pediatric ICU (PICU) transfers. METHODS: I-PASS-to-PICU was iteratively developed in a single PICU. A core PICU stakeholder group collaboratively designed an electronic health record (EHR)-supported clinical note template by adapting elements from I-PASS, an evidence-based handoff program, to support information exchange between referring clinicians and receiving PICU physicians. I-PASS-to-PICU is a receiver-driven tool used by PICU physicians to guide verbal communication and electronic documentation during PICU transfer calls. The template underwent three cycles of iterative evaluation and redesign informed by individual and group interviews of multidisciplinary PICU staff, usability testing using simulated and actual referral calls, and debriefing with PICU physicians. RESULTS: Individual and group interviews with 21 PICU staff members revealed that relevant, accurate, and concise information was needed for adequate admission preparedness. Time constraints and secondhand information transmission were identified as barriers. Usability testing with six receiving PICU physicians using simulated and actual calls revealed good usability on the validated System Usability Scale (SUS), with a mean score of 77.5 (standard deviation 10.9). Fellows indicated that most fields were relevant and that the template was feasible to use. CONCLUSION: I-PASS-to-PICU was technically feasible, usable, and relevant. The authors plan to further evaluate its effectiveness in improving information exchange during real-time PICU practice.

Unfamiliar personal protective equipment: The role of routine practice and other factors affecting healthcare personnel doffing strategies.

BACKGROUND: Healthcare personnel (HCP) may encounter unfamiliar personal protective equipment (PPE) during clinical duties, yet we know little about their doffing strategies in such situations. OBJECTIVE: To better understand how HCP navigate encounters with unfamiliar PPE and the factors that influence their doffing strategies. SETTING: The study was conducted at 2 Midwestern academic hospitals. PARTICIPANTS: The study included 70 HCP: 24 physicians and resident physicians, 31 nurses, 5 medical or nursing students, and 10 other staff. Among them, 20 had special isolation unit training. METHODS: Participants completed 1 of 4 doffing simulation scenarios involving 3 mask designs, 2 gown designs, 2 glove designs, and a full PPE ensemble. Doffing simulations were video-recorded and reviewed with participants during think-aloud interviews. Interviews were audio-recorded and analyzed using thematic analysis. RESULTS: Participants identified familiarity with PPE items and designs as an important factor in doffing. When encountering unfamiliar PPE, participants cited aspects of their routine practices such as designs typically used, donning and doffing frequency, and design cues, and their training as impacting their doffing strategies. Furthermore, they identified nonintuitive design and lack of training as barriers to doffing unfamiliar PPE appropriately. CONCLUSION: PPE designs may not be interchangeable, and their use may not be intuitive. HCP drew on routine practices, experiences with familiar PPE, and training to adapt doffing strategies for unfamiliar PPE. In doing so, HCP sometimes deviated from best practices meant to prevent self-contamination. Hospital policies and procedures should include ongoing and/or just-in-time training to ensure HCP are equipped to doff different PPE designs encountered during clinical care.

Reporting Outcomes of Pediatric Intensive Care Unit Patients to Referring Physicians via an Electronic Health Record-Based Feedback System.

BACKGROUND: Many critically ill children are initially evaluated in front-line settings by clinicians with variable pediatric training before they are transferred to a pediatric intensive care unit (PICU). Because clinicians learn from past performance, communicating outcomes of patients back to front-line clinicians who provide pediatric emergency care could be valuable; however, referring clinicians do not consistently receive this important feedback. OBJECTIVES: Our aim was to determine the feasibility, usability, and clinical relevance of a semiautomated electronic health record (EHR)-supported system developed at a single institution to deliver timely and relevant PICU patient outcome feedback to referring emergency department (ED) physicians. METHODS: Guided by the Health Information Technology Safety Framework, we iteratively designed, implemented, and evaluated a semiautomated electronic feedback system leveraging the EHR in one institution. After conducting interviews and focus groups with stakeholders to understand the PICU-ED health care work system, we designed the EHR-supported feedback system by translating stakeholder, organizational, and usability objectives into feedback process and report requirements. Over 6 months, we completed three cycles of implementation and evaluation, wherein we analyzed EHR access logs, reviewed feedback reports sent, performed usability testing, and conducted physician interviews to determine the system's feasibility, usability, and clinical relevance. RESULTS: The EHR-supported feedback process is feasible with timely delivery and receipt of feedback reports. Usability testing revealed excellent Systems Usability Scale scores. According to physicians, the process was well-integrated into their clinical workflows and conferred minimal additional workload. Physicians also indicated that delivering and receiving consistent feedback was relevant to their clinical practice. CONCLUSION: An EHR-supported system to deliver timely and relevant PICU patient outcome feedback to referring ED physicians was feasible, usable, and important to physicians. Future work is needed to evaluate impact on clinical practice and patient outcomes and to investigate applicability to other clinical settings involved in similar care transitions.

Usability of smart infusion pumps: A heuristic evaluation.

Although smart infusion pumps were built to eliminate medication errors, new types of usability errors have arisen. The purposes of this study were to determine potential risks when using smart pumps during secondary medication administration and to identify opportunities for design improvements. We observed and analyzed nurses when they interacted with smart pumps and heuristically evaluated the smart pump to identify usability problems. Forty-three usability problems were identified with the smart pump. The usability problems have the potential to create high cognitive burden on nurses and to increase the likelihood of mistakes. We discuss design and process improvement recommendations for each major finding from this study.

Usability of state public health department websites for communication during a pandemic: A heuristic evaluation.

Study aims were to investigate how usable COVID-19 dedicated state public health websites in the US were, and whether case counts in different geographical regions in the US were related to website usability. 16 state websites representing the 2 highest and the 2 lowest case count states in each region were selected. Five experts used a heuristic evaluation procedure to independently rate all 16 websites on a severity scale of 0-4. Usability criteria published by the US Department of Health and Human Services and criteria on risk communication and data dashboards were used. Analyses involved cross tabulation of usability criteria with case counts, comparison of usability scores using Mood's median tests, test of differences in average usability scores using ANOVA and post-hoc tests, and identification of correlations between case counts and usability scores. Results from the Mood's median test showed that the median usability scores for the states were significantly different from each other at the 5% level of significance (df = 15, chi-square = 38.40; p = 0.001). ANOVA showed statistically significant differences between the mean usability scores for the states at the 5% level of significance (F = 6.33, p < 0.05). Although not statistically significant, results from a correlation analysis between case count and usability scores showed a negative correlation (r = -0.209, p = 0.437) indicating that the higher the case count, the better the usability score. Overall, the websites fared well on usability, but many websites were used as an information and data repository. These websites must communicate infection risk better. RELEVANCE TO INDUSTRY: The study applies to public health agency websites that communicate essential information during a pandemic.

Follow, select and assemble method FSAM for VE and re assembly.

We modified the methods by Ballard et al. [1]. They sought to study eye-hand coordination strategies and created both a real world and a virtual model copying task consisting of three different areas: model, source, and workspace. Participants followed a pickup and place exercise and used a mouse to control stimuli presented on a computer monitor in the virtual task. We also considered the method presented by Hayhoe et al. [2] and Aivar et al. [3] who designed a similar model copying task in a 3D virtual environment. Stimuli were displayed in a head mounted display and participants held a motion sensor to select and move virtual objects in 3D space. Moreover, Aivar et al. [3] also included extra assembly pieces and a variation in the position of the assembly pieces located in the resource area. • It proposes an assembly task designed at a 1:1 scale for two environments, real and virtual environments. • It introduces a reading sequence for the model that is being replicated and it also introduces distractor assembly blocks with similar colors and shapes as the required assembly blocks, and a change in the location for all assembly blocks in the resource area. • It modifies the interaction for the VR environment by using hand gestures to select, move and position virtual assembly blocks. This was possible by incorporating a LEAP® motion controller which although it does not provide haptic feedback, it provides a virtual representation of the participant's hand. Our VE also includes visual and auditory feedback to guide depth perception and virtual control. The software used for this research study is available at: http://virtualete.com/research/fsam.php.

A Theoretical Framework for Understanding Creator-Consumer Information Interaction Behaviors in Healthcare Documentation Systems.

The advent of electronic documentation systems has made it easy to generate and store vast amounts of information, and has enabled easy access to patient care information, so much so that they are now considered a critical infrastructure for supporting the cognitive tasks in healthcare work. But, electronic documentation systems are not without their share of problems. Accountability and liability requirements have made electronic information creation and documentation particularly challenging. Mandatory documentation requirements and templated electronic formats have increased the amount of information, but have not always resulted in reliable, useful, or meaningful information. Documentation systems have become rigid, offering little opportunity for healthcare providers to engage in meaningful conversations about the information, and to sense problem status without additional coordination. A particularly significant information interaction problem that we have identified from our field work in healthcare information modeling, which this paper focuses on, deals with what we term creator-consumer interaction behaviors. The purpose of this paper is to examine in-depth the problem of creator-consumer information interaction behaviors in electronic healthcare documentation systems. A creator-consumer interaction behavioral framework highlights satisficing behavior during creation and consumption of medical documentation, and the characteristics of the work system that may lead to satisficing on documentation tasks.

Healthcare Workers' Strategies for Doffing Personal Protective Equipment.

BACKGROUND: Personal protective equipment (PPE) helps protect healthcare workers (HCWs) from pathogens and prevents cross-contamination. PPE effectiveness is often undermined by inappropriate doffing methods. Our knowledge of how HCWs approach doffing PPE in practice is limited. In this qualitative study, we examine HCWs' perspectives about doffing PPE. METHODS: Thirty participants at a Midwestern academic hospital were recruited and assigned to 1 of 3 doffing simulation scenarios: 3 mask designs (n = 10), 2 gown designs (n = 10), or 2 glove designs (n = 10). Participants were instructed to doff PPE as they would in routine practice. Their performances were video-recorded and reviewed with participants. Semistructured interviews about their doffing approaches were conducted and audio-recorded, then transcribed and thematically analyzed. RESULTS: Three overarching themes were identified in interviews: doffing strategies, cognitive processes, and barriers and facilitators. Doffing strategies included doffing safely (minimizing self-contamination) and doffing expediently (eg, ripping PPE off). Cognitive processes during doffing largely pertained to tracking contaminated PPE surfaces, examining PPE design cues (eg, straps), or improvising based on prior experience from training or similar PPE designs. Doffing barriers and facilitators typically related to PPE design, such as PPE fit (or lack of it) and fastener type. Some participants also described personal barriers (eg, glasses, long hair); however, some PPE designs helped mitigate these barriers. CONCLUSIONS: Efforts to improve HCWs' doffing performance need to address HCWs' preferences for both safety and expediency when using PPE, which has implications for PPE design, training approaches, and hospital policies and procedures.

BALANCING DOCUMENTATION AND DIRECT PATIENT CARE ACTIVITIES: A STUDY OF A MATURE ELECTRONIC HEALTH RECORD SYSTEM.

US hospitals now fully embrace electronic documentation systems as a way to reduce medical errors and improve patient safety outcomes. Whether spending time on electronic documentation detracts from the time available for direct patient care, however, is still unresolved. There is no knowledge on the permanent effects of documenting electronically and whether it takes away significant time from patient care when the healthcare information system is mature. To understand the time spent on documentation, direct patient care tasks, and other clinical tasks in a mature information system, we conducted an observational and interview study in a midwestern academic hospital. The hospital implemented an electronic medical record system 11 years ago. We observed 22 health care workers across intensive care units, inpatient floors, and an outpatient clinic in the hospital. Results show that healthcare workers spend more time on documentation activities compared to patient care activities. Clinical roles have no influence on the time spent on documentation. This paper describes results on the time spent between documentation and patient care tasks, and discusses implications for future practice. RELEVANCE TO INDUSTRY: The study applies to healthcare industry that faces immense challenges in balancing documentation activities and patient care activities.

A qualitative investigation of healthcare workers' strategies in response to readmissions.

BACKGROUND: Readmission of a patient to a hospital is typically associated with significant clinical changes in the patient's condition, but it is unknown how healthcare workers modify their provision of care when considering these changes. The purpose of the present study was to determine how healthcare workers shift their care strategies when treating readmitted patients. METHODS: A typical case sampling study of healthcare workers was conducted using the grounded theory approach. The study setting comprised several patient care units at an academic center and tertiary-care hospital. We purposively sampled 34 healthcare workers (19 women, 15 men) to participate in individual interviews, either face-to-face or by telephone. We asked the participants semi structured questions regarding their thoughts on readmissions and how they altered their process and behavior for readmitted patients. Interviews were audio-recorded and transcribed. We used a qualitative data analyses based on an inductive approach to generate themes about how healthcare workers shift their strategies for readmitted patients. RESULTS: Healthcare workers' shifts in strategy for readmissions were reflected in three major themes: clinical assessment, use and management of information, and communication patterns. Participants reported that they became more conservative in their assessment of the clinical condition of a readmitted patient. The participants also indicated that readmitted patients would be treated in a similar way to normal admission based on care requirements; however, somewhat paradoxically, they also expressed that having access to prior patient information changed the way they treated a readmitted patient. CONCLUSIONS: Although healthcare workers may exhibit a tendency to become more conservative with readmissions, readily available patient information from the previous admission played a large part in guiding their thinking. A more conservative approach with a readmitted patient, on its own, does not necessarily lead to improved documentation or better patient care.

Initial development of the Systems Approach to Home Medication Management (SAHMM) model.

BACKGROUND: Adverse drug events and medication nonadherence are two problems associated with prescription medication use for chronic conditions. These issues often develop because patients have difficulty managing their medications at home. To guide patients and providers for achieving safe and effective medication use at home, the Systems Approach to Home Medication Management (SAHMM) model was derived from a systems engineering model for health care workplace safety. OBJECTIVE: To explore how well concepts from the SAHMM model can represent home medication management by using patient descriptions of how they take prescription medications at home. METHODS: Twelve patients were interviewed about home medication management using an interview guide based on the factors of the SAHMM model. Each interview was audio-taped and then transcribed verbatim. Interviews were coded to identify themes for home medication management using MAXQDA for Windows. RESULTS: SAHMM concepts extracted from the coded interview transcripts included work system components of person, tasks, tools & technology, internal environment, external environment, and household. Concepts also addressed work processes and work outcomes for home medication management. CONCLUSIONS: Using the SAHMM model for studying patients' home medication management is a promising approach to improving our understanding of the factors that influence patient adherence to medication and the development of adverse drug events.

Role of Human Factors Engineering in Infection Prevention: Gaps and Opportunities.

Human factors engineering (HFE), with its focus on studying how humans interact with systems, including their physical and organizational environment, the tools and technologies they use, and the tasks they perform, provides principles, tools, and techniques for systematically identifying important factors, for analyzing and evaluating how these factors interact to increase or decrease the risk of Healthcare-associated infections (HAI), and for identifying and implementing effective preventive measures. We reviewed the literature on HFE and infection prevention and control and identified major themes to document how researchers and infection prevention staff have used HFE methods to prevent HAIs and to identify gaps in our knowledge about the role of HFE in HAI prevention and control. Our literature review found that most studies in the healthcare domain explicitly applying (HFE) principles and methods addressed patient safety issues not infection prevention and control issues. In addition, most investigators who applied human factors principles and methods to infection prevention issues assessed only one human factors element such as training, technology evaluations, or physical environment design. The most significant gap pertains to the limited use and application of formal HFE tools and methods. Every infection prevention study need not assess all components in a system, but investigators must assess the interaction of critical system components if they want to address latent and deep-rooted human factors problems.

Usability Evaluation and Implementation of a Health Information Technology Dashboard of Evidence-Based Quality Indicators.

Health information technology dashboards that integrate evidence-based quality indicators can efficiently and accurately display patient risk information to promote early intervention and improve overall quality of patient care. We describe the process of developing, evaluating, and implementing a dashboard designed to promote quality care through display of evidence-based quality indicators within an electronic health record. Clinician feedback was sought throughout the process. Usability evaluations were provided by three nurse pairs and one physician from medical-surgical areas. Task completion times, error rates, and ratings of system usability were collected to compare the use of quality indicators displayed on the dashboard to the indicators displayed in a conventional electronic health record across eight experimental scenarios. Participants rated the dashboard as "highly usable" following System Usability Scale (mean, 87.5 [SD, 9.6]) and Poststudy System Usability Questionnaire (mean, 1.7 [SD, 0.5]) criteria. Use of the dashboard led to reduced task completion times and error rates in comparison to the conventional electronic health record for quality indicator-related tasks. Clinician responses to the dashboard display capabilities were positive, and a multifaceted implementation plan has been used. Results suggest application of the dashboard in the care environment may lead to improved patient care.

Design Implications to Increase Utilization of Stairwells.

Stairwell use is a cost-effective opportunity to increase physical activity. Although stairwell use can integrate moderate physical activity in daily work routines, little information is available to guide architects and engineers on how to design facilities that promote stairwell use. This study examined the reasons behind using stairwells versus elevators through a case study at a teaching hospital. A broad range of physical design recommendations were evaluated to understand how the design of stairwells can encourage hospital staff and students to use them. An online survey was used to collect data. Findings indicated travel distance and travel direction as primary reasons for preferring elevators. Design recommendations such as motivational signs and physical movement reinforcements (e.g., cardio indicators) are discussed.

Aligning complex processes and electronic health record templates: a quality improvement intervention on inpatient interdisciplinary rounds.

BACKGROUND: Interdisciplinary rounds (IDR) with documentation have become a standard of care, but the process has been incompletely described in academic general medical settings. Checklists are promoted, yet standardized formats may not reflect the variability and work flow of rounds or support the cognitive development of medical trainees. We describe IDR processes in an academic general medicine inpatient setting and present a rapid cycle quality improvement (QI) project that improved IDR documentation rates in the electronic health record. METHODS: The project team observed existing daily IDR rounds on two medical inpatient units at the Iowa City VA Medical Center, with three resident teams and maximum census of 42 patients. The major intervention was a redesigned note template, with accompanying resident educational materials. The primary outcome was note completion rates by charge nurses; IDR team member satisfaction and participation, discussion time and balancing metrics (i.e., excess bed days of care, length of stay, and 30-day readmissions) were also assessed. RESULTS: An electronic template and accompanying educational materials designed to parallel the heuristic problem-solving activities of the IDR team led to improvements in IDR note completion rates from 27 to 69 %. Team member satisfaction was high and participation was stable. Discussion time per patient increased modestly, but varied widely between resident teams and by patient. Balancing metrics were unchanged. Unstructured evaluation indicated that documentation times were reduced, and IDR documentation became more timely and useful. CONCLUSIONS: IDR notes designed to support the problem-solving processes of an interdisciplinary group improved the timeliness and perceived value of IDR documentation and met regulatory standards. Aligning complex processes and educational and documentation needs during IDR may create an efficient opportunity for sustainable interdisciplinary work and learning in an academic setting.

How lapse and slip errors influence head-of-bed angle compliance rates as measured by a portable, wireless data collection system.

The recommended protocols to prevent ventilator-associated pneumonia include keeping ventilated patients' head and upper body elevated to an angle between 30 and 45 degrees. These recommendations are largely based on a study that has been difficult to replicate, because studies that have attempted to replicate the original conditions have failed to achieve the necessary bed angles consistently. This work suggests the possibility that two specific types of human error, slips and lapses, contribute to non-compliant bed angles. A novel device provided 83,655 samples of bed angles over a period of 1579 hours. The bed angle was out of compliance 64.2% of the time analyzed. Slips, the accident of raising the bed to an angle slightly less than the desired angle, accounted for most of the out-of-compliance measurements, or 55.9% of the time analyzed. It appears that stochastic variation in the bed adjustments results in the bed being out of compliance. Interventions should be investigated such as increasing the target angle and providing feedback at the moment the bed is raised to close to, but less than, the target angle.

Technologies in the wild (TiW): human factors implications for patient safety in the cardiovascular operating room.

We describe different sources of hazards from cardiovascular operating room (CVOR) technologies, how hazards propagate in the CVOR and their impact on cognitive processes. Previous studies have examined hazards from poor design of a specific CVOR technology. However, the impact of different CVOR technologies functioning in context is not clearly understood. In addition, the impact of non-design hazards in technology devices is unclear. Our study identified hazards from organisational, physical/environmental elements, in addition to design of technology in a CVOR. We used observations, follow-up interviews and photographs. With qualitative analyses, we categorised the different hazard sources and their potential impact on cognitive processes. Patient safety can be built into technologies by incorporating user needs in design, decision-making and implementation of medical technologies. PRACTITIONER SUMMARY: Effective design and implementation of technology in a safety-critical system requires prospective understanding of technology-related hazards. Our research fills this gap by studying different technologies in context of a CVOR using observations. Qualitative analyses identified different sources for technology-related hazards besides design, and their impact on cognitive processes.

Using human factors engineering to improve patient safety in the cardiovascular operating room.

Despite significant medical advances, cardiac surgery remains a high risk procedure. Sub-optimal work system design characteristics can contribute to the risks associated with cardiac surgery. However, hazards due to work system characteristics have not been identified in the cardiovascular operating room (CVOR) in sufficient detail to guide improvement efforts. The purpose of this study was to identify and categorize hazards (anything that has the potential to cause a preventable adverse patient safety event) in the CVOR. An interdisciplinary research team used prospective hazard identification methods including direct observations, contextual inquiry, and photographing to collect data in 5 hospitals for a total 22 cardiac surgeries. We performed thematic analysis of the qualitative data guided by a work system model. 60 categories of hazards such as practice variations, high workload, non-compliance with evidence-based guidelines, not including clinicians' in medical device purchasing decisions were found. Results indicated that hazards are common in cardiac surgery and should be eliminated or mitigated to improve patient safety. To improve patient safety in the CVOR, efforts should focus on creating a culture of safety, increasing compliance with evidence based infection control practices, improving communication and teamwork, and designing better tools and technologies through partnership among all stakeholders.

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.
