Usability of a Human Factors-based Clinical Decision Support in the Emergency Department: Lessons Learned for Design and Implementation.

OBJECTIVE: To evaluate the usability and use of human factors (HF)-based clinical decision support (CDS) implemented in the emergency department (ED). BACKGROUND: Clinical decision support can improve patient safety; however, the acceptance and use of CDS has faced challenges. Following a human-centered design process, we designed a CDS to support pulmonary embolism (PE) diagnosis in the ED. We demonstrated high usability of the CDS during scenario-based usability testing. We implemented the HF-based CDS in one ED in December 2018. METHOD: We conducted a survey of ED physicians to evaluate the usability and use of the HF-based CDS. We distributed the survey via Qualtrics, a web-based survey platform. We compared the computer system usability questionnaire scores of the CDS between those collected in the usability testing to use of the CDS in the real environment. We asked physicians about their acceptance and use of the CDS, barriers to using the CDS, and areas for improvement. RESULTS: Forty-seven physicians (56%) completed the survey. Physicians agreed that diagnosing PE is a major problem and risk scores can support the PE diagnostic process. Usability of the CDS was reported as high, both in the experimental setting and the real clinical setting. However, use of the CDS was low. We identified several barriers to the CDS use in the clinical environment, in particular a lack of workflow integration. CONCLUSION: Design of CDS should be a continuous process and focus on the technology's usability in the context of the broad work system and clinician workflow.

Usage of a Web-Based Workplace and Symptom Self-Management Intervention Tool to Improve Work Ability for Breast Cancer Survivors.

This work aimed to evaluate the usage of a web-based intervention (WISE: Work ability Improvement through Symptom and Ergonomic strategies) developed to improve work ability for women recently diagnosed with breast cancer. Twenty-two women undergoing adjuvant treatment for breast cancer were provided access to WISE. This website includes content pages (e.g., information on ergonomics, symptom management, and other work-related resources) and worksheets (e.g., journals to track symptoms or goals). It could be personalized based on individual work activities and symptoms. Measures assessed at 3 months included usage of the website and perceived usefulness. Thirteen of the 22 participants (60%) accessed WISE; 11 personalized their information. Content and worksheet pages had 97 and 79 visits, respectively. Most frequently visited pages were "setting goals" (i.e., prioritize and track symptoms; 45 visits) and "steps to creating your WISE plan" (i.e., incorporate symptom and ergonomic strategies; 16 visits). Median duration time was 11.05 (range 0.35-79.55) minutes. Usefulness of the content and worksheet pages assessed via a 7-point Likert scale (1 = strongly disagree, 7 = strongly agree) was 5.08 (SD = 1.59) and 4.26 (SD = 2.03), respectively. Participants were likely to recommend WISE to other women undergoing cancer treatment (mean = 6.11; SD = 1.05). The majority of participants personalized WISE work and symptom strategies. Overall, participants agreed that WISE content pages were useful and would recommend WISE for other breast cancer survivors. Results support that majority of breast cancer survivors, undergoing treatment with curative intent, accessed a web-based intervention that provided personalized information on workplace and symptom strategies.

Results from a prospective longitudinal survey of employment and work outcomes in newly diagnosed cancer patients during and after curative-intent chemotherapy: A Wisconsin Oncology Network study.

BACKGROUND: Postcancer work limitations may affect a substantial proportion of patients and contribute to the "financial toxicity" of cancer treatment. The degree and nature of work limitations and employment outcomes are poorly understood for cancer patients, particularly in the immediate period of transition after active treatment. We prospectively examined employment, work ability, and work limitations during and after treatment. METHODS: A total of 120 patients receiving curative therapy who were employed prior to their cancer diagnosis and who intended to work during or after end of treatment (EOT) completed surveys at baseline (pretreatment), EOT, and 3, 6, and 12 months after EOT. Surveys included measures of employment, work ability, and work limitations. Descriptive statistics (frequencies, percentages, means with standard deviations) were calculated. RESULTS: A total of 111 participants completed the baseline survey. On average, participants were 48 years of age and were mostly white (95%) and female (82%) with a diagnosis of breast cancer (69%). Full-time employment decreased during therapy (from 88% to 50%) and returned to near prediagnosis levels by 12-month follow-up (78%). Work-related productivity loss due to health was high during treatment. CONCLUSIONS: This study is the first to report the effects of curative intent cancer therapy on employment, work ability, and work limitations both during and after treatment. Perceived work ability was generally high overall 12 months after EOT, although a minority reported persistent difficulty. A prospective analysis of factors (eg, job type, education, symptoms) most associated with work limitations is underway to assist in identifying at-risk patients.

Evaluation of Intraoperative Hand-Off Frequency, Duration, and Context: A Mixed Methods Analysis.

BACKGROUND: Hand-offs in the operating room contribute to poor communication, reduced team function, and may be poorly coordinated with other activities. Conversely, they may represent a missed opportunity for improved communication. We sought to better understand the coordination and impact of intraoperative hand-offs. METHODS: We prospectively audio-video (AV) recorded 10 operations and evaluated intraoperative hand-offs. Data collected included percentage of time team members were absent due to breaks, relationships between hand-offs and intraoperative events (incision, surgical counts), and occurrences of simultaneous hand-offs. We also identified announcement that a hand-off had occurred and anchoring, in which team members not involved in the hand-off participated and provided information. RESULTS: Spanning 2919 min of audio-video data, there were 74 hand-offs (range, 4-14 per case) totaling 225.2 min, representing 7.7% of time recorded. Thirty-two (45.1%) hand-offs were interrupted or delayed because of competing activities; eight hand-offs occurred during an instrument or laparotomy pad count. Six cases had simultaneous hand-offs; two cases had two episodes of simultaneous hand-offs. Eight hand-offs included an announcement. Seven included anchoring. Evaluating both temporary and permanent hand-offs, one or more original team members was absent for 40.7% of time recorded and >one team member was absent for 20.5% of time recorded. CONCLUSIONS: Intraoperative hand-offs are frequent and not well coordinated with intraoperative events including counts and other hand-offs. Anchoring and announced hand-offs occurred in a small proportion of cases. Future work must focus on optimizing timing, content, and participation in intraoperative hand-offs.

Beyond the corrective action hierarchy: A systems approach to organizational change.

BACKGROUND: Many patient safety organizations recommend the use of the action hierarchy (AH) to identify strong corrective actions following an investigative analysis of patient harm events. Strong corrective actions, such as forcing functions and equipment standardization, improve patient safety by either preventing the occurrence of active failures (i.e. errors or violations) or reducing their consequences if they do occur. PROBLEM: We propose that the emphasis on implementing strong fixes that incrementally improve safety one event at a time is necessary, yet insufficient, for improving safety. This singular focus has detracted from the pursuit of major changes that transform systems safety by targeting the latent conditions which consistently underlie active failures. To date, however, there are no standardized models or methods that enable patient safety professionals to assess, develop and implement systems changes to improve patient safety. APPROACH: We propose a multifaceted definition of 'systems change'. Based on this definition, various types and levels of systems change are described. A rubric for determining the extent to which a specific corrective action reflects a 'systems change' is provided. This rubric incorporates four fundamental dimensions of systems change: scope, breadth, depth and degree. Scores along these dimensions can then be used to classify corrective actions within our proposed systems change hierarchy (SCH). CONCLUSION: Additional research is needed to validate the proposed rubric and SCH. However, when used in conjunction with the AH, the SCH perspective will serve to foster a more holistic and transformative approach to patient safety.

A randomized trial of immediate versus delayed survivorship care plan receipt on patient satisfaction and knowledge of diagnosis and treatment.

BACKGROUND: Survivorship care plans (SCPs) and care-planning sessions have been recommended for over a decade, yet evidence for their benefit remains mixed. In a randomized trial, changes in survivor knowledge and satisfaction before and after the receipt of an SCP were assessed. METHODS: Patients with breast cancer who had completed curative-intent treatment were randomized to immediate versus delayed receipt of an individualized SCP. All participants completed the modified Wisconsin Survey of Cancer Diagnosis and Management in Breast Cancer and the Preparing for Life As a New Survivor survey to assess individual knowledge about cancer diagnosis, treatment, side effects, and follow-up as well as satisfaction with communication and care coordination. Surveys were completed at baseline, at 4 weeks (before delayed receipt), and again at 12 weeks (after all participants had received SCPs); the primary outcome was change in knowledge at 4 weeks. RESULTS: In total, 127 eligible women were randomized. An improvement in individual knowledge was observed between baseline and week 12 for both arms combined (+1.6; 95% confidence interval, 0.9-2.3; P < .001). There was no statistically significant difference in the change in knowledge from baseline through week 4 between the arms. No significant change occurred for satisfaction scores over time. CONCLUSIONS: This randomized trial of immediate versus delayed SCP receipt demonstrated a small improvement (4%) in survivor knowledge. However, this improvement did not appear to be related to SCP provision. The authors hypothesized that the improvement was because of repeated administration of the knowledge survey. If improved survivor knowledge is a goal, then strategies beyond the 1-time provision and review of an SCP should be explored.

Familiarity and Communication in the Operating Room.

BACKGROUND: Poor communication is implicated in many adverse events in the operating room (OR); however, many hospitals' scheduling practices permit unfamiliar operative teams. The relationship between unfamiliarity, team communication and effectiveness of communication is poorly understood. We sought to evaluate the relationship between familiarity, communication rates, and communication ineffectiveness of health care providers in the OR. MATERIALS AND METHODS: We performed purposive sampling of 10 open operations. For each case, six providers (anesthesiology attending, in-room anesthetist, circulator, scrub, surgery attending, and surgery resident) were queried about the number of mutually shared cases. We identified communication events and created dyad-specific communication rates. RESULTS: Analysis of 48 h of audio-video content identified 2570 communication events. Operations averaged 58.0 communication events per hour (range, 29.4-76.1). Familiarity was not associated with communication rate (P = 0.69) or communication ineffectiveness (P = 0.21). Cross-disciplinary dyads had lower communication rates than intradisciplinary dyads (P < 0.001). Anesthesiology-nursing, anesthesiology-surgery, and nursing-surgery dyad communication rates were 20.1%, 42.7%, and 57.3% the rate predicted from intradisciplinary dyads, respectively. In addition, cross-disciplinary dyad status was a significant predictor of having at least one ineffective communication event (P = 0.02). CONCLUSIONS: Team members do not compensate for unfamiliarity by increasing their verbal communication, and dyad familiarity is not protective against ineffective communication. Cross-disciplinary communication remains vulnerable in the OR suggesting poor crosstalk across disciplines in the operative setting. Further investigation is needed to explore these relationships and identify effective interventions, ensuring that all team members have the necessary information to optimize their performance.

Scope and Influence of Electronic Health Record-Integrated Clinical Decision Support in the Emergency Department: A Systematic Review.

STUDY OBJECTIVE: As electronic health records evolve, integration of computerized clinical decision support offers the promise of sorting, collecting, and presenting this information to improve patient care. We conducted a systematic review to examine the scope and influence of electronic health record-integrated clinical decision support technologies implemented in the emergency department (ED). METHODS: A literature search was conducted in 4 databases from their inception through January 18, 2018: PubMed, Scopus, the Cumulative Index of Nursing and Allied Health, and Cochrane Central. Studies were included if they examined the effect of a decision support intervention that was implemented in a comprehensive electronic health record in the ED setting. Standardized data collection forms were developed and used to abstract study information and assess risk of bias. RESULTS: A total of 2,558 potential studies were identified after removal of duplicates. Of these, 42 met inclusion criteria. Common targets for clinical decision support intervention included medication and radiology ordering practices, as well as more comprehensive systems supporting diagnosis and treatment for specific disease entities. The majority of studies (83%) reported positive effects on outcomes studied. Most studies (76%) used a pre-post experimental design, with only 3 (7%) randomized controlled trials. CONCLUSION: Numerous studies suggest that clinical decision support interventions are effective in changing physician practice with respect to process outcomes such as guideline adherence; however, many studies are small and poorly controlled. Future studies should consider the inclusion of more specific information in regard to design choices, attempt to improve on uncontrolled before-after designs, and focus on clinically relevant outcomes wherever possible.

Role network measures to assess healthcare team adaptation to complex situations: the case of venous thromboembolism prophylaxis.

Hospitals are complex environments that rely on clinicians working together to provide appropriate care to patients. These clinical teams adapt their interactions to meet changing situational needs. Venous thromboembolism (VTE) prophylaxis is a complex process that occurs throughout a patient's hospitalisation, presenting five stages with different levels of complexity: admission, interruption, re-initiation, initiation, and transfer. The objective of our study is to understand how the VTE prophylaxis team adapts as the complexity in the process changes; we do this by using social network analysis (SNA) measures. We interviewed 45 clinicians representing 9 different cases, creating 43 role networks. The role networks were analysed using SNA measures to understand team changes between low and high complexity stages. When comparing low and high complexity stages, we found two team adaptation mechanisms: (1) relative increase in the number of people, team activities, and interactions within the team, or (2) relative increase in discussion among the team, reflected by an increase in reciprocity.   Practitioner Summary: The reason for this study was to quantify team adaptation to complexity in a process using social network analysis (SNA). The VTE prophylaxis team adapted to complexity by two different mechanisms, by increasing the roles, activities, and interactions among the team or by increasing the two-way communication and discussion throughout the team. We demonstrated the ability for SNA to identify adaptation within a team.

A Statewide Surgical Coaching Program Provides Opportunity for Continuous Professional Development.

OBJECTIVE: We sought to develop and evaluate a video-based coaching program for board-eligible/certified surgeons. SUMMARY BACKGROUND DATA: Multiple disciplines utilize coaching for continuous professional development; however, coaching is not routinely employed for practicing surgeons. METHODS: Peer-nominated surgeons were trained as coaches then paired with participant surgeons. After setting goals, each coaching pair reviewed video-recorded operations performed by the participating surgeon. Coaching sessions were audio-recorded, transcribed, and coded to identify topics discussed. The effectiveness with which our coaches were able to utilize the core principles and activities of coaching was evaluated using 3 different approaches: self-evaluation; evaluation by the participants; and assessment by the study team. Surveys of participating surgeons and coach-targeted interviews provided general feedback on the program. All measures utilized a 5-point Likert scale format ranging from 1 (low) to 5 (high). RESULTS: Coach-participant surgeon pairs targeted technical, cognitive, and interpersonal aspects of performance. Other topics included managing intraoperative stress. Mean objective ratings of coach effectiveness was 3.1 ±â€Š0.7, ranging from 2.0 to 5.0 on specific activities of coaching. Subjective ratings by coaches and participants were consistently higher. Coaches reported that the training provided effectively prepared them to facilitate coaching sessions. Participants were similarly positive about interactions with their coaches. Identified barriers were related to audio-video technology and scheduling of sessions. Overall, participants were satisfied with their experience (mean 4.4 ±â€Š0.7) and found the coaching program valuable (mean 4.7 ±â€Š0.7). CONCLUSIONS: This is the first report of cross-institutional surgical coaching for the continuous professional development of practicing surgeons, demonstrating perceived value among participants, as well as logistical challenges for implementing this evidence-based program. Future research is necessary to evaluate the impact of coaching on practice change and patient outcomes.

Understanding Why Quality Initiatives Succeed or Fail: A Sociotechnical Systems Perspective.

Efforts to implement quality improvements in surgery are notoriously problematic. One needs to look no farther than recent attempts to implement checklists, team training, and surgical briefings. These interventions have been empirically shown to improve team communication and performance. Yet numerous barriers to implementation have limited their broad adoption and use. Apparently, knowing the remedy (intervention) does not translate into knowing how to administer (implement) it. Or in surgical terms, knowing "what" procedure needs to be performed does not necessarily mean that one knows "how" to perform it. Surgeons serve a vital leadership role in driving quality and patient safety initiatives in the operating room. Achieving success requires both an in-depth understanding of the intervention and the complex dynamics of the elements involved in the implementation process. To aid in this endeavor, the present article describes a Model for Understanding System Transitions Associated with the Implementation of New Goals (MUSTAING). The model highlights important variables associated with implementation success. It also provides a tool for diagnosing why certain interventions may not have worked as intended so that improvements in the implementation process can be made. Finally, the model offers a general framework for guiding future implementation or "how to" research.

Flow disruptions during trauma care.

BACKGROUND: Flow disruptions (FDs) are deviations from the progression of care that compromise safety or efficiency. The frequency and specific causes of FDs remain poorly documented in trauma care. We undertook this study to identify and quantify the rate of FDs during various phases of trauma care. METHODS: Seven trained observers studied a Level I trauma center over 2 months. Observers recorded details on FDs using a validated Tablet-PC data collection tool during various phases of care-trauma bay, imaging, operating room (OR)-and recorded work-system variables including breakdowns in communication and coordination, environmental distractions, equipment issues, and patient factors. RESULTS: Researchers observed 86 trauma cases including 72 low-level and 14 high-level activations. Altogether, 1,759 FDs were recorded (20.4/case). High-level trauma comprised a significantly higher number (p = 0.0003) and rate of FDs (p = 0.0158) than low-level trauma. Across the three phases of trauma care, there was a significant effect on FD number (p < 0.0001) and FD rate (p = 0.0005), with the highest in the OR, followed by computed tomography. The highest rates of FD per case and per hour were related to breakdowns in coordination. CONCLUSIONS: This study is the largest direct observational study of the trauma process conducted to date. Complexities associated with the critical patient who arrives in the trauma bay lead to a high prevalence of disruptions related to breakdowns in coordination, communication, equipment issues, and environmental factors. Prospective observation allows individual hospitals to identify and analyze these systemic deficiencies. Appropriate interventions can then be evaluated to streamline the care provided to trauma patients.

Development and evaluation of a survey to assess survivor knowledge change after survivorship care plans: WiSDOM-B (Wisconsin Survey of cancer DiagnOsis and Management in Breast cancer).

The oncology community has increased efforts to inform survivors about long-term risks and planned follow-up after cancer treatment. Survivorship care plans (SCPs) have been recommended since 2005, yet the benefits of implementation are only now being emphasized. SCPs are hypothesized to enhance patient knowledge. The Wisconsin Survey of Diagnosis and Management in Breast Cancer (WiSDOM-B) was developed to measure changes in breast cancer survivor knowledge pre- and postdelivery of an SCP. The WiSDOM-B was developed with input from oncologists (medical, radiation, and surgical), patient advocates, cancer survivors, and survey design experts. Initially, nine patients evaluated survey content, and modifications were made to enhance clarity. Subsequently, 38 patients were enrolled in a randomized pilot trial assessing SCP impact on knowledge of diagnosis, treatment, late effects, and follow-up (WiSDOM-B) and satisfaction with knowledge (existing survey). The WiSDOM-B was developed using feedback from multiple stakeholders. Baseline knowledge was poor and remained stable in the control arm. There was a suggestion of increased survivor knowledge following receipt of SCPs in the intervention arm (68.4 vs. 74.4%). Change was not statistically significant compared with the control arm. Despite knowledge deficits, baseline satisfaction with knowledge was high for both groups, with 100% of patients being satisfied/very satisfied with information provided. Satisfaction did not change significantly following SCP receipt. The WiSDOM-B assesses survivor knowledge of cancer diagnosis, treatment, follow-up, and side effects. It will be a useful tool for future studies assessing the impact of care plans on survivor knowledge.

Dashboarding to Monitor Machine-Learning-Based Clinical Decision Support Interventions.

BACKGROUND: Existing monitoring of machine-learning-based clinical decision support (ML-CDS) is focused predominantly on the ML outputs and accuracy thereof. Improving patient care requires not only accurate algorithms but also systems of care that enable the output of these algorithms to drive specific actions by care teams, necessitating expanding their monitoring. OBJECTIVES: In this case report, we describe the creation of a dashboard that allows the intervention development team and operational stakeholders to govern and identify potential issues that may require corrective action by bridging the monitoring gap between model outputs and patient outcomes. METHODS: We used an iterative development process to build a dashboard to monitor the performance of our intervention in the broader context of the care system. RESULTS: Our investigation of best practices elsewhere, iterative design, and expert consultation led us to anchor our dashboard on alluvial charts and control charts. Both the development process and the dashboard itself illuminated areas to improve the broader intervention. CONCLUSION: We propose that monitoring ML-CDS algorithms with regular dashboards that allow both a context-level view of the system and a drilled down view of specific components is a critical part of implementing these algorithms to ensure that these tools function appropriately within the broader care system.

Academic Detailing as a Health Information Technology Implementation Method: Supporting the Design and Implementation of an Emergency Department-Based Clinical Decision Support Tool to Prevent Future Falls.

BACKGROUND: Clinical decision support (CDS) tools that incorporate machine learning-derived content have the potential to transform clinical care by augmenting clinicians' expertise. To realize this potential, such tools must be designed to fit the dynamic work systems of the clinicians who use them. We propose the use of academic detailing-personal visits to clinicians by an expert in a specific health IT tool-as a method for both ensuring the correct understanding of that tool and its evidence base and identifying factors influencing the tool's implementation. OBJECTIVE: This study aimed to assess academic detailing as a method for simultaneously ensuring the correct understanding of an emergency department-based CDS tool to prevent future falls and identifying factors impacting clinicians' use of the tool through an analysis of the resultant qualitative data. METHODS: Previously, our team designed a CDS tool to identify patients aged 65 years and older who are at the highest risk of future falls and prompt an interruptive alert to clinicians, suggesting the patient be referred to a mobility and falls clinic for an evidence-based preventative intervention. We conducted 10-minute academic detailing interviews (n=16) with resident emergency medicine physicians and advanced practice providers who had encountered our CDS tool in practice. We conducted an inductive, team-based content analysis to identify factors that influenced clinicians' use of the CDS tool. RESULTS: The following categories of factors that impacted clinicians' use of the CDS were identified: (1) aspects of the CDS tool's design (2) clinicians' understanding (or misunderstanding) of the CDS or referral process, (3) the busy nature of the emergency department environment, (4) clinicians' perceptions of the patient and their associated fall risk, and (5) the opacity of the referral process. Additionally, clinician education was done to address any misconceptions about the CDS tool or referral process, for example, demonstrating how simple it is to place a referral via the CDS and clarifying which clinic the referral goes to. CONCLUSIONS: Our study demonstrates the use of academic detailing for supporting the implementation of health information technologies, allowing us to identify factors that impacted clinicians' use of the CDS while concurrently educating clinicians to ensure the correct understanding of the CDS tool and intervention. Thus, academic detailing can inform both real-time adjustments of a tool's implementation, for example, refinement of the language used to introduce the tool, and larger scale redesign of the CDS tool to better fit the dynamic work environment of clinicians.

Mapping the process of ICU care delivery to improve treatment decisions in acute respiratory failure.

Evidence suggests system-level norms and care processes influence individual patients' medical decisions, including end-of-life decisions for patients with critical illnesses like acute respiratory failure. Yet, little is known about how these processes unfold over the course of a patient's critical illness in the intensive care unit (ICU). Our objective was to map current-state ICU care delivery processes for patients with acute respiratory failure and to identify opportunities to improve the process. We conducted a process mapping study at two academic medical centers, using focus groups and semi-structured interviews. The 70 participants represented 17 distinct roles in ICU care, including interprofessional medical ICU and palliative care clinicians, surrogate decision makers, and patient survivors. Participants refined and endorsed a process map of current-state care delivery for all patients admitted to the ICU with acute respiratory failure requiring mechanical ventilation. The process contains four critical periods for active deliberation about the use of life-sustaining treatments. However, active deliberation steps are inconsistently performed and frequently disrupted, leading to prolongation of life-sustaining treatment by default, without consideration of patients' individual goals and priorities. Interventions to standardize active deliberation in the ICU may improve treatment decisions for ICU patients with acute respiratory failure.

Understanding clinical implementation coordinators' experiences in deploying evidence-based interventions.

PURPOSE: The fluoroquinolone restriction for the prevention of Clostridioides difficile infection (FIRST) trial is a multisite clinical study in which sites carry out a preauthorization process via electronic health record-based best-practice alert (BPA) to optimize the use of fluoroquinolone antibiotics in acute care settings. Our research team worked closely with clinical implementation coordinators to facilitate the dissemination and implementation of this evidence-based intervention. Clinical implementation coordinators within the antibiotic stewardship team (AST) played a pivotal role in the implementation process; however, considerable research is needed to further understand their role. In this study, we aimed to (1) describe the roles and responsibilities of clinical implementation coordinators within ASTs and (2) identify facilitators and barriers coordinators experienced within the implementation process. METHODS: We conducted a directed content analysis of semistructured interviews, implementation diaries, and check-in meetings utilizing the conceptual framework of middle managers' roles in innovation implementation in healthcare from Urquhart et al. RESULTS: Clinical implementation coordinators performed a variety of roles vital to the implementation's success, including gathering and compiling information for BPA design, preparing staff, organizing meetings, connecting relevant stakeholders, evaluating clinical efficacy, and participating in the innovation as clinicians. Coordinators identified organizational staffing models and COVID-19 interruptions as the main barriers. Facilitators included AST empowerment, positive relationships with staff and oversight/governance committees, and using diverse implementation strategies. CONCLUSION: When implementing healthcare innovations, clinical implementation coordinators facilitated the implementation process through their roles and responsibilities and acted as strategic partners in improving the adoption and sustainability of a fluoroquinolone preauthorization protocol.

Flow disruptions in trauma care handoffs.

BACKGROUND: Effective handoffs of care are critical for maintaining patient safety and avoiding communication problems. Using the flow disruption observation technique, we examined transitions of care along the trauma pathway. We hypothesized that more transitions would lead to more disruptions, and that different pathways would have different numbers of disruptions. METHODS: We trained observers to identify flow disruptions, and then followed 181 patients from arrival in the emergency department (ED) to the completion of care using a specially formatted PC tablet. We mapped each patient's journey and recorded and classified flow disruptions during transition periods into seven categories. RESULTS: Mapping the transitions of care shows that approximately four of five patients were assessed in the ED, transferred to imaging for further diagnostics, and then returned to the ED. There was a mean of 2.2 ± 0.09 transitions per patient, a mean of 0.66 ± 0.15 flow disruptions per patient, and 0.31 ± 0.07 flow disruptions per transition. Most of these (53%) were related to coordination problems. Although disruptions did not rise with more transitions, patients who went directly to the operating room or needed direct admission to intensive care unit were significantly more likely (P=0.0028) to experience flow disruptions than those who took other, less expedited pathways. CONCLUSIONS: Transitions in trauma care are vulnerable to systems problems and human errors. Coordination problems predominate as the cause. Sicker, time-pressured, and more at-risk patients are more likely to experience problems. Safety practices used in motor racing and other industries might be applied to address these problems.

Post-implementation usability evaluation of a human factors-based clinical decision support for pulmonary embolism (PE) diagnosis (Dx): PE Dx Study Part 1.

While there is promise for health IT, such as Clinical Decision Support (CDS), to improve patient safety and clinician efficiency, poor usability has hindered widespread use of these tools. Human Factors (HF) principles and methods remain the gold standard for health IT design; however, there is limited information on how HF methods and principles influence CDS usability "in the wild". In this study, we explore the usability of an HF-based CDS used in the clinical environment; the CDS was designed according to a human-centered design process, which is described in Carayon et al. (2020). In this study, we interviewed 12 emergency medicine physicians, identifying 294 excerpts of barriers and facilitators of the CDS. Sixty-eight percent of excerpts related to the HF principles applied in the human-centered design of the CDS. The remaining 32% of excerpts related to 18 inductively-created categories, which highlight gaps in the CDS design process. Several barriers were related to the physical environment and organization work system elements as well as physicians' broader workflow in the emergency department (e.g., teamwork). This study expands our understanding of the usability outcomes of HF-based CDS "in the wild". We demonstrate the value of HF principles in the usability of CDS and identify areas for improvement to future human-centered design of CDS. The relationship between these usability outcomes and the HCD process is explored in an accompanying Part 2 manuscript.
