abstract = {One of the most common errors in intraoperative medication delivery is the result of “syringe swap,” when syringes that have been mixed up lead to the incorrect administration of a drug. An improvement of syringe organization could reduce medication administration errors. Recently, there have been many efforts to improve medication organization; however, these interventions struggle to achieve widespread use, even though they typically report substantial improvements in error rates and medication awareness in home institutions. A syringe organization hub was developed based on observations, interviews, and past designs. In order to assess the perceived acceptance of the hub, we used the Technology Acceptance Model (TAM) to develop a survey that was distributed to anesthesia providers at two medical institutions in the United States: one in the Mid-Atlantic and one in the southeast. The results of the four different linear regression models revealed that participants at the southeastern institution had significantly lower usefulness ratings (p<0.001), attitude ratings (p<0.001), and behavioral intent ratings (p<0.05) than participants at the Mid-Atlantic institution. The participants at the southeastern institution also reported more concerns about the implementation of the device, specifically regarding workflow deviation and cleanliness. The hub design was heavily influenced by the workflows and work practices of the Mid-Atlantic institution, and survey results found that this may have created barriers for acceptance at the southeastern institution. We found that, as barriers continue to go unaddressed at a given institution, even the simplest device can become disruptive to workflow, and there can be a struggle with integration. When interventions are developed, they are typically designed to address the barriers at the native institution. However, when seeking widespread adoption, small barriers to acceptance at non-native institutions can prevent adoption of interventions as they are not inherently factored into the design. Therefore, widespread adoption can only be accomplished by expanding the number of institutions in the design process, thereby accounting for the barriers to adoption and acceptance.},

abstract = {BACKGROUND The rising adoption of telehealth provides new opportunities for more effective and equitable health care information mediums. The ability of chatbots to provide a conversational, personal, and comprehendible avenue for learning about health care information make them a promising tool for addressing health care inequity as health care trends continue toward web-based and remote processes. Although chatbots have been studied in the health care domain for their efficacy for smoking cessation, diet recommendation, and other assistive applications, few studies have examined how specific design characteristics influence the effectiveness of chatbots in providing health information. OBJECTIVE Our objective was to investigate the influence of different design considerations on the effectiveness of an educational health care chatbot. METHODS A 2×3 between-subjects study was performed with 2 independent variables: a chatbot's complexity of responses (eg, technical or nontechnical language) and the presented qualifications of the chatbot's persona (eg, doctor, nurse, or nursing student). Regression models were used to evaluate the impact of these variables on 3 outcome measures: effectiveness, usability, and trust. A qualitative transcript review was also done to review how participants engaged with the chatbot. RESULTS Analysis of 71 participants found that participants who received technical language responses were significantly more likely to be in the high effectiveness group, which had higher improvements in test scores (odds ratio [OR] 2.73, 95% CI 1.05-7.41; P=.04). Participants with higher health literacy (OR 2.04, 95% CI 1.11-4.00},

abstract = {Summary 

Literature focused on quantifying or reducing patient harm in anaesthesia uses a variety of labels and definitions to represent patient safety-related events, such as ‘medication errors', ‘adverse events', and ‘critical incidents'. This review extracts and compares definitions of patient safety-related terminology in anaesthesia to examine the scope of this variability and inconsistencies. A structured review was performed in which 36 of the 769 articles reviewed met the inclusion criteria. Similar terms were grouped into six categories by similarities in keyword choice (Adverse Event, Critical Incident, Medication Error, Error, Near Miss, and Harm) and their definitions were broken down into three base components to allow for comparison. Our analysis found that the Medication Error category, which encompasses the greatest number of terms, had widely variant definitions which represent fundamentally different concepts. Definitions of terms within the other categories consistently represented relatively similar concepts, though key variations in wording remain. This inconsistency in terminology can lead to problems with synthesising, interpreting, and overall sensemaking in relation to anaesthesia medication safety. Guidance towards how ‘medication errors’ should be defined is provided, yet a definition will have little impact on the future of patient safety without organisations and journals taking the lead to promote, publish, and standardise definitions.},

abstract = {Objectives: This work examines the variability in how different anesthesia providers approach patient care to provide insight into the source and necessity of variations in practice, the implications of different individual preferences, and the subsequent consequences on approaches to safety that emphasize standardization. Methods: Vignette-based interviews were performed with 18 anesthesia providers to elicit the cognitive processes and strategies that they utilize as they progress through a case. A qualitative data analysis of the transcripts was performed to illuminate the variability in their processes of managing the case. Results: Participants employed converging strategies consistent with prior literature. However, divergence occurs in the application of those strategies; there is variability in participants’ information seeking strategies, problem anticipation, and resulting actions. In some instances, this divergence was minor, representing natural preferences that would inevitably converge in the management of the case. In other instances, this divergence represented major deviations that would not converge throughout the management of the case. Conclusions: The differences in how anesthesia providers approach their work, as identified in this study, call into question whether ‘standardization’ is always the best approach to improve safety in anesthesia. Whatever the cause of variations in individual strategies, when developing new approaches, the variability in anesthesia information seeking, goal setting and anticipation needs to be reflected in policies, practices, protocols, and training. This work reinforces the idea that it is the humans in the system, with their flexibility and expertise, who are the primary source of everyday safety.},

abstract = {3D gestural technology for HCI could transform the way people interact with computing systems. There are traditionally two approaches to developing gestural technology systems: a human-based approach where usability is maximized and a technology-based approach where system accuracy is maximized. The tradeoff between usability and accuracy may negatively affect the overall trust and reliability in the system. Therefore, this study seeks to redefine the human-based approach to gestural system development by introducing a bottom-up approach to identifying the lower-level features that produce a gesture, thus allowing the technology to accurately recognize features. A user elicitation study was performed, and gestures were classified according to a novel feature extraction gesture taxonomy and a traditional taxonomy of classifying gestures as a unit. The feature-extraction approach revealed several advantages because it fosters a bottom-up approach to identifying gesture features. Using this approach may mitigate the effects of the usability-accuracy tradeoff in gestural system development.},

abstract = {Background: Electronic health record (EHR) patient portals are designed to provide medical health records to patients. Using an EHR portal is expected to contribute to positive health outcomes and facilitate patient-provider communication. Objective: Our objective was to examine how portal users report using their portals and the factors associated with obtaining health information from the internet. We also examined the desired portal features, factors impacting users' trust in portals, and barriers to using portals. Methods: An internet-based survey study was conducted using Amazon Mechanical Turk. All the participants were adults in the United States who used patient portals. The survey included questions about how the participants used their portals, what factors acted as barriers to using their portals, and how they used and how much they trusted other web-based health information sources as well as their portals. A logistic regression model was used to examine the factors influencing the participants' trust in their portals. Additionally, the desired features and design characteristics were identified to support the design of future portals. Results: A total of 394 participants completed the survey. Most of the participants were less than 35 years old (212/394, 53.8%), with 36.3% (143/394) aged between 35 and 55 years, and 9.9% (39/394) aged above 55 years. Women accounted for 48.5% (191/394) of the survey participants. More than 78% (307/394) of the participants reported using portals at least monthly. The most common portal features used were viewing lab results, making appointments, and paying bills. Participants reported some barriers to portal use including data security and limited access to the internet. The results of a logistic regression model used to predict the trust in their portals suggest that those comfortable using their portals (odds ratio [OR] 7.97, 95% CI 1.11-57.32) thought that their portals were easy to use (OR 7.4, 95% CI 1.12-48.84), and frequent internet users (OR 43.72, 95% CI 1.83-1046.43) were more likely to trust their portals. Participants reporting that the portals were important in managing their health (OR 28.13, 95% CI 5.31-148.85) and that their portals were a valuable part of their health care (OR 6.75, 95% CI 1.51-30.11) were also more likely to trust their portals. Conclusions: There are several factors that impact the trust of EHR patient portal users in their portals. Designing easily usable portals and considering these factors may be the most effective approach to improving trust in patient portals. The desired features and usability of portals are critical factors that contribute to users' trust in EHR portals.},

However, little is known about the influence that workspace design has on the ability to perform complex operating theatre (OT) work. The aim of this study was to observe the relationship between task switching and physical layout, and then use the data collected to design and assess different anaesthesia workspace layouts. Methods: In this observational study, six videos of anaesthesia providers were analysed from a single centre in the United States. A task analysis of workflow during the maintenance phase of anaesthesia was performed by categorising tasks. The data supported evaluations of alternative workspace designs. Results: An anaesthesia provider's time was occupied primarily by three tasks: patient (mean: 30.0% of total maintenance duration), electronic medical record (26.6%), and visual display tasks (18.6%). The mean time between task switches was 6.39 s. With the current workspace layout, the anaesthesia provider was centred toward the patient for approximately half of the maintenance duration. Evaluating the alternative layout designs showed how equipment arrangements could improve task switching and increase the provider's focus towards the patient and visual displays. Conclusions: Our study showed that current operating theatre layouts do not fit work demands. We report a simple method that facilitates a quick layout design assessment and showed that the anaesthesia workspace can be improved to better suit workflow and patient care. Overall, this arrangement could reduce anaesthesia workload while improving task flow efficiency and potentially the safety of care.},

abstract = {3D gestural input technology has the ability to expand human-computer interaction (HCI) beyond traditional input modalities. It is known that context and domain expertise are influential to gesture development, but there is little known about other individual factors such as workload and exposure. Therefore, the objective of this work is to explore the effects of workload and exposure on intuitive gesture choice and reaction time under a general HCI context. A longitudinal study was conducted to investigate the differences in intuitive mappings for high and low workload conditions as well as across three separate experimental sessions. There were no differences in the intuitive mappings for either workload conditions or different experimental sessions. However, there was a difference in reaction times between all experimental sessions indicating there was a learning effect from the first to the last session in that the participants became faster in generating intuitive mappings.},

abstract = {Background: The internet has enabled convenient and efficient health information searching which is valuable for individuals with chronic conditions requiring some level of self-management. However, there is little research evaluating what factors may impact the use of the internet for health-related tasks for specific clinical populations, such as individuals with inflammatory bowel diseases. Objective: Our goal was to investigate the factors that influence internet use in acquiring health information by individuals with inflammatory bowel diseases. Specifically, we identified factors associated with internet searching behavior and using the internet for completing health-related tasks. Methods: We used 2016 National Health Interview Survey weighted data to develop logistic regression models to predict the likelihood that individuals with inflammatory bowel diseases would use the internet for 2 types of tasks: seeking health information through online searches and using the internet to perform health-related tasks including scheduling appointments and emailing care providers. Results: 2016 National Health Interview Survey weighted data include more than 3 million weighted adult respondents with inflammatory bowel diseases (approximately 1.29% of adults in the weighted data set). Our results suggest that approximately 66.3% of those with inflammatory bowel diseases reported using the internet at least once a day, and approximately 14.7% reported being dissatisfied with their current health care. About 62.3% of those with inflammatory bowel diseases reported that they had looked up health information online, 16.3% of those with inflammatory bowel diseases reported that they had scheduled an appointment with a health care provider online, and 21.6% reported having used a computer to communicate with a health provider by email. We found that women who were self-regulating their care were more likely to look up health information online than others. Both middle-aged and older adults with inflammatory bowel diseases who were unsatisfied with their current health care were less likely to look up health information online. Frequent internet users who were worried about medical costs were more likely to look up health information online. Similarly, the results from our statistical models suggest that individuals with inflammatory bowel diseases who were frequent internet users were more likely to use the internet for specific health-related tasks. Additionally, women with inflammatory bowel diseases who reported being married were less likely to use the internet for specific health-related tasks. Conclusions: For those with inflammatory bowel diseases, there are additional socioeconomic and behavioral factors that impact the use of the internet for health information and health-related tasks. Future research should evaluate how these factors moderate the use of the internet and identify how online resources can support clinical populations in ways that improve access to information, support health self-management, and subsequently improve health outcomes.},

abstract = {Nurses in intensive care units are exposed to hundreds of alarms during a shift, and research shows that most alarms are not clinically relevant. Alarm fatigue can occur when a nurse becomes desensitized to alarms. Alarm fatigue can jeopardize patient safety, and adverse alarm events can lead to patients dying.To evaluate how a process intervention affects the number of alarms during an 8-hour shift in an intensive care unit.A total of 62 patients from an intensive care unit were included in the study; 32 of these patients received the intervention, which included washing the patient’s chest with soap and water and applying new electrocardiography electrodes at the start of a shift. The number of alarms, clinical diagnoses, and demographic variables were collected for each patient. A Poisson regression model was used to evaluate the impact of the intervention on the overall number of clinical alarms during the shift, with no adjustments to the alarm settings or other interventions.After relevant covariates are controlled for, the results suggest that patients in the intervention group presented significantly fewer alarms than did patients in the control group.Managing clinical alarms is a main issue in terms of both patient safety and staff workload management. The results of this study demonstrate that a relatively simple process-oriented strategy can decrease the number of alarms.},

abstract = {Gestures are a natural input method for human communication and may be effective for drivers to interact with in-vehicle infotainment systems (IVIS). Most of the existing work on gesture-based human-computer interaction (HCI) in and outside of the vehicle focus on the distinguishability of computer systems. The purpose of this study was to identify gesture sets that are used for IVIS tasks and to compare task times across the different functions for gesturing and touchscreens. Task times for user-defined gestures were quicker than for a novel touchscreen. There were several functions that resulted in relatively intuitive gesture mappings (e.g., zooming in and zooming out on a map) and others that did not have strong mappings across participants (e.g., decreasing volume and playing the next song). The findings of this study suggest that user-centric gestures can be utilized to interact with IVIS systems instead of touchscreens, and future work should evaluate how to account for variability in intuitive gestures. Understanding the gesture variability among the end users can support the development of an in-vehicle gestural input system that is intuitive for all users.},

abstract = {Abstract The patient-centered care model supports patients actively engaging in their care. Typically this involves collecting patient-reported outcomes and priorities that may not be part of the routine practice. There is a research gap related to whether there is time available within the routine orthopedic medical practice to collect patient-centered data for immediate use without delaying the overall clinical processes or influencing patient clinical experiences. A time study was conducted to quantify the current patient processes at an orthopedic clinic, and a statistical simulation model was used to evaluate potential changes in patients? clinical process if a patient-centered survey were to be implemented. The proportion of simulated patients who would experience delays due to the survey, the durations of their delays, and the average duration of the patient process delay were recorded at each step in the clinical process. The results are presented in terms of the relationship between the time devoted to collecting data and the impact on the patient experience for various survey durations at various process points. This study demonstrates an approach to evaluate how introducing a patient priorities survey (for collecting both patient-reported outcomes and priorities), which could be used in the same patient visit, might impact the clinical process and introduce process delays.},

abstract = {The physical environment affects how work is done in operating rooms (OR). The circulating nurse (CN), in particular, requires access to and interacts with materials, equipment, and technology more than other OR team members. Naturalistic study of CN behavior is therefore valuable in assessing how OR space and physical configuration influences work patterns and disruptions. This study evaluated the CNs' work patterns and flow disruptions (FD)by analyzing 25 surgeries across three different ORs. The OR layouts were divided into transitional and functional zones, and the work of CNs was categorized into patient, equipment, material, and information tasks. The results reveal that information tasks involve less movement than other types of work, while across all ORs, CNs were more likely to be involved in layout and environmental hazard FDs when involved in patient, material, or equipment-related tasks compared to information tasks. Different CN work patterns and flow disruptions between ORs suggest a link between OR layout and a CN's work. Future studies should examine how specific layout elements influence outcomes.},
