Adjustments of Ventilator Parameters during Operating Room-to-ICU Transition and 28-Day Mortality.

Rationale: Lung-protective mechanical ventilation strategies have been proven beneficial in the operating room (OR) and the ICU. However, differential practices in ventilator management persist, often resulting in adjustments of ventilator parameters when transitioning patients from the OR to the ICU. Objectives: To characterize patterns of ventilator adjustments during the transition of mechanically ventilated surgical patients from the OR to the ICU and assess their impact on 28-day mortality. Methods: Hospital registry study including patients undergoing general anesthesia with continued, controlled mechanical ventilation in the ICU between 2008 and 2022. Ventilator parameters were assessed 1 hour before and 6 hours after the transition. Measurements and Main Results: Of 2,103 patients, 212 (10.1%) died within 28 days. Upon OR-to-ICU transition, VT and driving pressure decreased (-1.1 ml/kg predicted body weight [IQR, -2.0 to -0.2]; P < 0.001; and -4.3 cm H2O [-8.2 to -1.2]; P < 0.001). Concomitantly, respiratory rates increased (+5.0 breaths/min [2.0 to 7.5]; P < 0.001), resulting overall in slightly higher mechanical power (MP) in the ICU (+0.7 J/min [-1.9 to 3.0]; P < 0.001). In adjusted analysis, increases in MP were associated with a higher 28-day mortality rate (adjusted odds ratio, 1.10; 95% confidence interval, 1.06-1.14; P < 0.001; adjusted risk difference, 0.7%; 95% confidence interval, 0.4-1.0, both per 1 J/min). Conclusion: During transition of mechanically ventilated patients from the OR to the ICU, ventilator adjustments resulting in higher MP were associated with a greater risk of 28-day mortality.

A peer-to-peer handoff tool to ease clerkship transitions.

EDUCATIONAL CHALLENGE: Frequent transitions between core clinical rotations in medical school increase anxiety and cognitive load. Few formalized programs exist to ease these transitions. Our institutional needs-assessment found that approximately 85% of students believed that additional rotation-specific information prior to starting a new rotation would reduce anxiety and increase success. PROPOSED SOLUTION AND IMPLEMENTATION OF SOLUTION: We developed a novel web-based peer-to-peer handoff tool available to all clerkship students at a single, large academic institution. The tool contains the names and contact information of students who most recently completed rotations on each service for all clerkships. A handoff checklist was also created with suggested discussion points for handoffs. Students were encouraged to schedule a handoff 1-2 weeks before starting a new rotation. LESSONS LEARNED: Overall, 83 students (66%) utilized the handoff tool, with use and efficacy decreasing with time during the clinical year. Of tool users, 65% expressed that having access to the tool prior to starting a new rotation helped to reduce anxiety, and 74% felt that the information gained helped to ease transitions. Our peer-to-peer handoff tool may help students feel more prepared to start a new rotation, decrease anxiety during clerkship year, and ease transitions. NEXT STEPS: This low-resource intervention may be implemented at other institutions to provide students with equal opportunities to receive valuable information prior to starting new rotations, regardless of pre-existing peer connections. An automated update system, which we are implementing at our institution, could greatly decrease the time required to maintain a handoff tool and improve sustainability.

Assessing current handover practices in surgery: A survey of non-consultant hospital doctors in Ireland.

BACKGROUND: Handovers of care are potentially hazardous moments in the patient journey and can lead to harm if conducted poorly. Through a national survey of surgical doctors in Ireland, this paper assesses contemporary surgical handover practices and evaluates barriers and facilitators of effective handover. METHODS: After ethical approval and pre-testing with a representative sample, a cross-sectional, online survey was distributed to non-consultant hospital doctors (NCHDs) working in the Republic of Ireland. A mixed-methods approach was used, combining data using triangulation design. MAIN FINDINGS: A total of 201 responses were received (18.5%). Most participants were senior house officers or senior registrars (49.7% and 37.3%). Most people (85.1%) reported that information received during handover was missing or incorrect at least some of the time. One-third of respondents reported that a near-miss had occurred as a result of handover within the past three months, and handover-related errors resulted in minor (16.9%), moderate (4.9%), or major (1.5%) harm. Only 11.4% had received any formal training. Reported barriers to handover included negative attitudes, a lack of institutional support, and competing clinical activities. Facilitators included process standardisation, improved access to resources, and staff engagement. CONCLUSIONS: Surgical NCHDs working in Irish hospitals reported poor compliance with international best practice for handover and identified potential harms. Process standardisation, appropriate staff training, and the provision of necessary handover-related resources is required at a national level to address this significant patient safety concern.

Decision-Making Algorithm with Geographic Mobility for Cognitive Radio.

The proposed novel algorithm named decision-making algorithm with geographic mobility (DMAGM) includes detailed analysis of decision-making for cognitive radio (CR) that considers a multivariable algorithm with geographic mobility (GM). Scarce research work considers the analysis of GM in depth, even though it plays a crucial role to improve communication performance. The DMAGM considerably reduces latency in order to accurately determine the best communication channels and includes GM analysis, which is not addressed in other algorithms found in the literature. The DMAGM was evaluated and validated by simulating a cognitive radio network that comprises a base station (BS), primary users (PUs), and CRs considering random arrivals and disappearance of mobile devices. The proposed algorithm exhibits better performance, through the reduction in latency and computational complexity, than other algorithms used for comparison using 200 channel tests per simulation. The DMAGM significantly reduces the decision-making process from 12.77% to 94.27% compared with ATDDiM, FAHP, AHP, and Dijkstra algorithms in terms of latency reduction. An improved version of the DMAGM is also proposed where feedback of the output is incorporated. This version is named feedback-decision-making algorithm with geographic mobility (FDMAGM), and it shows that a feedback system has the advantage of being able to continually adjust and adapt based on the feedback received. In addition, the feedback version helps to identify and correct problems, which can be beneficial in situations where the quality of communication is critical. Despite the fact that the FDMAGM may take longer than the DMAGM to calculate the best communication channel, constant feedback improves efficiency and effectiveness over time. Both the DMAGM and the FDMAGM improve performance in practical scenarios, the former in terms of latency and the latter in terms of accuracy and stability.

Analytical Model of the Connection Handoff in 5G Mobile Networks with Call Admission Control Mechanisms.

Handoff mechanisms are very important in fifth-generation (5G) mobile networks because of the cellular architecture employed to maximize spectrum utilization. Together with call admission control (CAC) mechanisms, they enable better optimization of bandwidth use. The primary objective of the research presented in this article is to analyze traffic levels, aiming to optimize traffic management and handling. This article considers the two most popular CAC mechanisms: the resource reservation mechanism and the threshold mechanism. It presents an analytical approach to occupancy distribution and blocking probability calculation in 5G mobile networks, incorporating connection handoff and CAC mechanisms for managing multiple traffic streams generated by multi-service sources. Due to the fact that the developed analytical model is an approximate model, its accuracy was also examined. For this purpose, the results of analytical calculations of the blocking probability in a group of 5G cells are compared with the simulation data. This paper is an extended version of our paper published in 17th ConTEL 2023.

Linguistic dissection of nursing handoffs: Implications for patient safety in varied-acuity hospital settings.

AIM: This study examines the intricate language and communication patterns of nurse-to-nurse handoffs across three units with varying patient acuity levels and nurse-patient ratios, seeking to identify linguistic factors that may affect the quality of information transfer and patient outcomes. DESIGN: A mixed-methods cross-sectional design. METHODS: This study used the Nurse-to-Nurse Transition of Care Communication Model to explore the content and meaning of language in nursing handoffs within a large academic medical centre. Data were collected on three units through digital audio recordings of 20 handoffs between June and September 2022, which were transcribed and analysed using the Linguistic Inquiry Word Count programme. Trustworthiness was established by adhering to COREQ and STROBE guidelines for qualitative and quantitative research, respectively. RESULTS: Analysis revealed a preference for casual, narrative language across all units, with ICU nurses demonstrating a higher confidence and leadership in communication. Cognitive processes such as insight and causation were found to be underrepresented, indicating a potential area for miscommunication. Communication motives driven by affiliation were more pronounced in ICU settings, suggesting a strong collaborative nature. No significant differences were observed among the units post multiple testing adjustments. Speech dysfluencies were most pronounced in ICU handoffs, reflecting possible stress and cognitive overload. CONCLUSION: The study highlights the need for improved communication strategies such as interventions to enhance language clarity and incorporating technological tools into handoff processes to mitigate potential miscommunications and errors. The findings advance nursing science by highlighting the critical role of nuanced language in varied-acuity hospital settings and the necessity for structured nurse education in handoff communication and standardized handoff procedures. IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE: This study underscores the critical role of language in nurse-to-nurse handoffs. It calls for enhanced communication strategies, technology integration and training to reduce medical errors, improving patient outcomes in high-acuity hospital settings. PATIENT OR PUBLIC CONTRIBUTION: Nurses only.

Development and effectiveness of a metaverse reality-based family-centered handoff education program in nursing students.

PURPOSE: Effective patient handoffs are vital in pediatric populations. This study aimed to develop and identify the impact of a metaverse-based handoff program using ZEPETO on nursing students' handoff competence, handoff self-efficacy, learning realism, and satisfaction. DESIGN AND METHODS: This study used a non-randomized, pre-post nonequivalent group design to develop, implement, and verify a metaverse-based handoff simulation program in a nursing school in South Korea. We assigned 69 senior nursing students from a university to an experimental group or a control group. We developed a metaverse-based, handoff simulation program of family-centered care by building a pediatric intensive care unit (PICU) using ZEPETO. The program included an online lecture, a metaverse rounding discussion, and a metaverse-based handoff simulation of postoperative care for infants with congenital heart disease. We measured handoff competence, handoff self-efficacy, learning realism, and learning satisfaction pre- and post-program. RESULT(S): The experimental group showed significantly higher handoff self-efficacy than the control group (t = 3.17, p = 0.002). No significant differences were found in handoff competency, learning realism, or learning satisfaction between the groups. CONCLUSION(S): This study confirmed that a family-centered care-based handoff metaverse simulation program based on the experiential learning theory enhanced nursing students' handoff self-efficacy. The program equipped students to conduct safe and effective handoffs in real-world clinical settings by providing an immersive learning experience and emphasizing patient-centered communication. PRACTICAL IMPLICATIONS: Based on these results, family-centered, handoff education programs are recommended to be developed that focus on learning realism and learning satisfaction to enhance nursing students' handoff competence.

Development of nursing handoff competency scale: a methodological study.

BACKGROUND: Nursing handoff competency is the ability of the nurse performing the handoff to select and interpret the necessary information for patient care and to convey it efficiently to the nurse accepting the handoff. Nursing handoff is an important nursing task that ensures nursing care continuity, quality and patient safety. This study aimed to develop a scale to measure nursing handoff competency and verify its validity and reliability. METHODS: This study adopted a methodological design. A research process included three phases: (1) scale development (literature review and interviews); (2) scale validation (validity and reliability); (3) standard setting. Data were collected from 496 clinical nurses currently working in hospital wards, intensive care units, and emergency rooms, and who independently perform a handoff in South Korea. RESULTS: The final scale comprises a self-reported 4-points Ilert scale with 25 items based on four factors: knowledge on handoff methods, identification of patient information, judgment and transfer of nursing situation, and "formation of supportive relationships. Construct validity, criterion-related validity, and discrimination validities were verified and the fitness of the scale revealed good results in confirmatory factor analysis. The Cronbach's α of the whole tool was.912 and the cut-off score for satisfied/unsatisfied was.72. CONCLUSIONS: The developed scale can evaluate the nurse's handoff competencies and determine whether training is necessary. The measurement results of the scale can be used to select training subjects and compose the contents of the education program.

The Quest for Excellence: A Quality Improvement Project on the Effects of a Standardized PACU/Phase II Bedside Report in a High Turnover Pediatric Ambulatory Surgery Center.

PURPOSE: To evaluate the impact of an evidence-based standardized bedside report within a pediatric ambulatory surgery center on length of handoff time, registered nurse (RN) workflow, and patient and family satisfaction. DESIGN: Quality improvement project using an evidence-based standardized bedside report intervention with pre- and postimplementation evaluation of process and outcome measures. METHODS: In January 2019, a unit-based task force evaluated ways to improve current report process and consistency of communication between staff and families. Time from admit into Phase II until nursing handoff was measured pre- and postimplementation. Nursing workflow was measured by time to first RN assessment after admit to Phase II and the postimplementation nursing survey. Patient and family satisfaction were measured pre- and postimplementation from National Research Council Health. FINDINGS: Postimplementation, average handoff times decreased by 30%; average time from admit to the Phase II unit until the nursing handoff decreased by 28%. From the postimplementation RN survey, 100% RNs: (1) felt standardized bedside report had a positive impact on their workflow, (2) expressed confidence in giving and receiving reports, and (3) reported they had critical information to safely care for patients. Overall patient satisfaction was measured by How likely would you be to recommend this facility to your family and friends; 11.6% improvement over baseline scores was reported. Improved percentages of score improvement from baseline included: nurses explained things (4.42%), nurses listened carefully (4.3%), patient and family received consistent information (2.46%), care providers explained things (2.22%), and patient and family trusted nurses with care (1.74%). CONCLUSIONS: Implementation of standardized bedside report resulted in (1) more expeditious times to handoff and first RN assessment, (2) overall positive impact on nursing workflow, and (3) improvements in patient and family satisfaction.

Implementation and Evaluation of the SBAR Communication Model in Nursing Handover by Pediatric Surgery Nurses.

PURPOSE: Situation, Background, Assessment, Recommendations (SBAR) is recommended as a standardized model to improve communication between health professionals and increase patient safety. Correct use of the SBAR model reduces communication errors, facilitates rapid decision-making, and increases patient safety. Therefore, effective use of the SBAR model among health care professionals contributes to safer patients. This study examines the implementation and evaluation of the SBAR communication model in nursing handover by pediatric surgical nurses. DESIGN: The study had a pretest-post-test semi-experimental design. METHODS: Data were collected between April 1 and June 30, 2022 from 24 nurses, who worked at two pediatric surgery units of a training research hospital in Turkey. Ethical approval and written informed consent were obtained prior to the study. FINDINGS: The mean age of the nurses was 26.00 ± 3.43 years and 75% were female. The mean score obtained from the handover rating scale was 60.33 ± 11.11 (18 to 70). The pretest and post-test scores obtained from the SBAR communication model questionnaire were 60.00 ± 20.64 (20 to 90) and 92.50 ± 9.89 (60 to 100), respectively. 66.7% of the nurses answered no to the statement "Using the SBAR communication model did not contribute positively to the handover." The majority answered yes to the items other than this statement, the ratio of those who answered yes and no to the statement "The SBAR communication model caused me to waste time during the handover" was equal, and the majority completed the SBAR handover form. CONCLUSIONS: Some of the nurses felt that the SBAR communication model made a positive contribution to shift performance, while others felt that it did not. Although half of the nurses considered the SBAR communication model to be a waste of time, it was observed that no negative events occurred during the use of the model and that the nurses were willing to use the SBAR communication model. Therefore, it is recommended that in-service training programs be organized to increase the use of the SBAR communication model and that the use of SBAR should be continuously reviewed and improved.

Don't interrupt me! development of a handoff education bundle to simulate the real world.

OBJECTIVES: Ineffective nurse-to-nurse handoff communication is associated with information omissions, diagnostic errors, treatment errors, and delays. New nurses report a lack of confidence and ability in handoff communication, which may stem from inadequate training in prelicensure nursing programs. Our objective was to introduce prelicensure nursing students to a standardized, theory-based method for handoff, including behavioral strategies employed by nurses during interrupted handoff. METHODS: A handoff education bundle (HEB) was developed. Kern's six-step curriculum model was utilized to design, implement, and evaluate the handoff curriculum. RESULTS: Student feedback highlighted the importance of integrating multiple, varying distractors during learning cycles and recognition of the impact of distractors on handoff. CONCLUSIONS: Implementing a HEB at the prelicensure nursing level could promote competency in handoff communication for new graduate nurses. IMPLICATIONS FOR INTERNATIONAL AUDIENCE: Handoff is an international patient safety priority, as inadequate communication has been linked to adverse patient events.

[Implementing bedside handover in neurological rehabilitation: An Action Research Approach in Practice Development]. / Implementation der patientennahen Übergabe in der neurologischen Frührehabilitation.

Implementing bedside handover in neurological rehabilitation: An Action Research Approach in Practice Development Abstract. Background: Nursing handovers are considered high-risk tasks but are also an important resource for conveying pertinent insights in the patients' situation and engaging them in the care process. As part of a broader action research project, a participatory approach was used to implement bedside handovers. Aims: It seemed central to sustainable change to gain insights which underlying factors motivate nurses to change handover practices. Methods: A qualitative design was chosen, in which five exploratory interviews were conducted with nurses. Results: The biggest challenges are privacy concerns and dealing with cognitively impaired patients. The motivations for bedside handover are a less error-prone transfer of information and a more accurate impression of the patient, in addition to a patient contact which is experienced as valuable. Discussion: The change in handover structure is accompanied by changes in the ward culture. The challenges faced by the staff require high communication skills to bridge them. The main factor for the preference of the handover form is the effect on the patients. Limitations: Transferability is limited due to the high contextual relevance. Transfer: With the help of a structured implementation strategy, even rituals can be modified. The bedside handover has a beneficial influence on patient-centredness.

Evaluating the Implementation of a Medical Student's Handoff Curriculum During the Surgery Clerkship.

INTRODUCTION: Early introduction to essential communication skills is important. We sought to determine if a handoff curriculum (HC) would improve confidence, decrease anxiety, and increase participation in clinical handoffs during the surgical clerkship. METHODS: A multi-center prospective cohort study was performed at two medical schools. Training in the intervention group (HC) consisted of a didactic lecture, video review, and practice session. Students completed a pre-clerkship knowledge test and confidence/anxiety/handoff experience questionnaire pre- and post-clerkship. RESULTS: There were no significant differences in pre-clerkship handoff experiences between institutions except having previously witnessed a verbal handoff (School A 96.4% versus School B 76.2%, P = 0.01). While there were no significant differences in post-clerkship confidence or anxiety, HC students were significantly more involved with written sign-outs (52.9% versus 18.2%, P = 0.02) and verbal handoffs (29.4% versus 4.6%, P = 0.03). CONCLUSIONS: Medical students exposed to handoff training shared similar confidence and anxiety scores compared to those that were not, however, they were more involved in handoff experiences during their surgical clerkship. Early introduction to handoff skills may encourage greater participation during subsequent clinical experiences.

Assessing North Texas Regional Trauma Handoffs: A Multicenter Mixed-Methods Needs Assessment.

INTRODUCTION: Trauma video review of Emergency Medical Services (EMS) handoffs demonstrates frequent problems including interruptions and incomplete information transfer. This study aimed to perform a regional needs assessment of handoff perceptions and expectations to guide future standardization efforts. METHODS: A multidisciplinary team of trauma providers through consensus building created an anonymous survey which was then distributed through the North Central Texas Trauma Regional Advisory Council and four regional level-1 trauma institutions. Qualitative data underwent content analysis; quantitative data are presented with descriptive statistics. RESULTS: Survey responses (n = 249) were submitted by trauma nurses (38%), EMS (24%), emergency physicians (14%), and trauma physicians (13%). Median overall handoff quality was rated well (4, scale 1-5) despite some variability between hospitals (3, scale 1-5). The top five most important handoff details were the same for both stable and unstable patients: primary mechanism, blood pressure, heart rate, Glasgow Coma Scale, and location of injuries. While providers felt neutral about the data order, the vast majority supported immediate bed transfer and primary survey in unstable patients. The majority of receiving providers report interrupting handoff at least once (78%); and 66% of EMS clinicians found interruptions disruptive. Content analysis revealed top priority categories for improvement: environment, communication, information relayed, team dynamics, and flow of care. CONCLUSION: Although our data demonstrated satisfaction and concordance with respect to the EMS handoff, 84% of EMS clinicians reported some to high amounts of variability across institutions. Gaps in the development of standardized handoffs identified include exposure, education, and enforcement of these protocols.

Guidelines and principles for the care of the cardiothoracic transplant patient in the intensive care unit.

Heart and lung transplant recipients require care provided by clinicians from multiple different specialties, each contributing unique expertise and perspective. The period the patient spends in the intensive care unit is one of the most critical times in the perioperative trajectory. Various organizational models of intensive care exist, including those led by intensivists, surgeons, transplant cardiologists, and pulmonologists. Coordinating timely efficient intensive care is an essential and logistically difficult goal. The present work product of the American Society of Transplantation's Thoracic and Critical Care Community of Practice, Critical Care Task Force outlines operational guidelines and principles that may be applied in different organizational models to optimize the delivery of intensive care for the cardiothoracic organ recipient.

The Warmest of Handoffs: A Neighborhood Physician's Transfer of Care.

Transitioning care of a patient from an outgoing to an incoming physician provides a precious opportunity to transfer knowledge and trust. We explore this process from the perspectives of 2 practitioners, an incoming physician who recently completed training and a retiring physician leaving a practice of 40 years. The method we arrived at for this transfer provided the space for collaboration on what the essence of caring for a unique individual will entail. We discovered that a handoff of care is the intergenerational transfer of culture. It involves worrying and watching and relaxing into hopefulness. It is both witnessing and launching a life's work. It is reliving and inheriting and reinventing relationship.

A scoping review of clinical handover mnemonic devices.

Since the Institute of Medicine (IOM) published To Err is Human: Building a Safer Health System in 1999, clinical handovers (or handoffs) and their relationship with the communication of patient safety have raised concerns from the public, regulatory bodies, and medical practitioners. Protocols, guidelines, forms, and mnemonic devices have been created to ensure safer clinical handovers. An initial literature search did not find a framework to describe the clinical processes and functions of each mnemonic device and its elements. The absence of a systematic framework could hinder the study across and the reusability of the established clinical handover mnemonic devices. This study aims to develop a universal framework to describe the clinical processes and functions essential for patient safety during handover. We queried PubMed.gov and obtained 98 articles related to clinical handovers. We examined the citing sources of the mnemonics mentioned in these articles. A total of 42 handover mnemonics with 238 elements were identified. Our review noted that there was no taxonomy to describe the clinical functions and process associated with the clinical handover mnemonic devices. We used grounded theory to address this gap and built a new taxonomy from the 42 mnemonics. A researcher read all mnemonics, developed a taxonomy for tagging clinical handover mnemonics, and categorized all mnemonic elements into correct processes and functions. After that, the second researcher, a medical practitioner, examined the taxonomy and made suggested corrections for the labelled functions of all mnemonic elements. Both researchers agreed on the taxonomy and the labelled processes and functions of different mnemonic elements. The taxonomy contains three processes and twenty functions in clinical handovers. Clinical processes like 'medical condition', 'medical history', 'medical evaluation', 'care plan', 'outstanding care/tasks/results', and 'patient information', as an administrative process, were widely adopted in clinical handover mnemonics. Moreover, mnemonic elements on communication manner and information validation had been identified in the list of clinical handover mnemonics. Although we recognize challenges because of both the vast number of clinical handover scenarios and the task of placing them under a few predefined groups, our findings suggest that such a taxonomy, as developed for this study, could assist medical practitioners to devise a clinical handover mnemonic to best fit their workplace.

Revisiting Feed Forward: Promoting a Student-Centered Approach to Education Handoffs, Remediation, and Clerkship Success.

Issue: Throughout medical school, and especially during clerkships, students experience changing work and learning environments and are exposed to new academic, interpersonal, and professional challenges unique to clinical learning. Given the siloed nature of clinical rotations, students often "fall through the cracks" and may repeatedly struggle through clerkships without support and coaching from which they would otherwise benefit. Many institutions have grappled with creating feed forward processes, that is, educational handoffs in which information is shared among faculty about struggling students with the intention of providing longitudinal support to ensure their success, while protecting students from negative bias that may follow them throughout the remainder of their medical school tenure. Evidence: Here, the authors describe the feed forward processes of four medical schools. Each school's process relies on close collaboration between course directors and deans to identify students and develop intervention plans. Course leadership and administration are typically the primary drivers for long-term follow-up with students. The number of participants in the process varies, with only one school directly involving students. Two schools hold larger, regularly scheduled meetings with up to 12 faculty present in their institution's feed forward process. Across these institutions, students can "graduate" from the feed forward process once they achieve competency in the areas of concern. Implications: The authors believe the most important outcome achieved is the formalization and adherence to a feed forward process. Thus, risk to students in the form of negative bias is mitigated by the flow of information, the extent to which information is available, and permitting students to be part of the process. These exemplars give insight into variable approaches to feed forward systems adopted by medical schools and demonstrate highly visible methodologies by which educational leadership empower students and educators toward a shared goal of student progress and achievement.

A Video-Based Study of Emergency Medical Services Handoffs to a Pediatric Emergency Department.

BACKGROUND: Emergency medical services (EMS) to emergency department (ED) handoffs are important moments in patient care, but patient information is communicated inconsistently. OBJECTIVE: The aim of this study was to describe the duration, completeness, and communication patterns of patient handoffs from EMS to pediatric ED clinicians. METHODS: We conducted a video-based, prospective study in the resuscitation suite of an academic pediatric ED. All patients 25 years and younger transported via ground EMS from the scene were eligible. We completed a structured video review to assess frequency of transmission of handoff elements, handoff duration, and communication patterns. We compared outcomes between medical and trauma activations. RESULTS: We included 156 of 164 eligible patient encounters from January to June 2022. Mean (SD) handoff duration was 76 (39) seconds. Chief symptom and mechanism of injury were included in 96% of handoffs. Most EMS clinicians communicated prehospital interventions (73%) and physical examination findings (85%). However, vital signs were reported for fewer than one-third of patients. EMS clinicians were more likely to communicate prehospital interventions and vital signs for medical compared with trauma activations (p < 0.05). Communication challenges between EMS clinicians and the ED were common; ED clinicians interrupted EMS or requested information already communicated by EMS in nearly one-half of handoffs. CONCLUSIONS: EMS to pediatric ED handoffs take longer than recommended and frequently lack important patient information. ED clinicians engage in communication patterns that may hinder organized, efficient, and complete handoff. This study highlights the need for standardizing EMS handoff and ED clinician education regarding communication strategies to ensure active listening during EMS handoff.

Innovative Spectrum Handoff Process Using a Machine Learning-Based Metaheuristic Algorithm.

A cognitive radio network (CRN) is an intelligent network that can detect unoccupied spectrum space without interfering with the primary user (PU). Spectrum scarcity arises due to the stable channel allocation, which the CRN handles. Spectrum handoff management is a critical problem that must be addressed in the CRN to ensure indefinite connection and profitable use of unallocated spectrum space for secondary users (SUs). Spectrum handoff (SHO) has some disadvantages, i.e., communication delay and power consumption. To overcome these drawbacks, a reduction in handoff should be a priority. This study proposes the use of dynamic spectrum access (DSA) to check for available channels for SU during handoff using a metaheuristic algorithm depending on machine learning. The simulation results show that the proposed "support vector machine-based red deer algorithm" (SVM-RDA) is resilient and has low complexity. The suggested algorithm's experimental setup offers several handoffs, unsuccessful handoffs, handoff delay, throughput, signal-to-noise ratio (SNR), SU bandwidth, and total spectrum bandwidth. This study provides an improved system performance during SHO. The inferred technique anticipates handoff delay and minimizes the handoff numbers. The results show that the recommended method is better at making predictions with fewer handoffs compared to the other three.
