In base-station-based underwater wireless acoustic networks (B-UWANs), effective handover mechanisms are necessary to ensure seamless data services for mobile nodes such as autonomous underwater vehicles (AUVs). Unlike terrestrial base stations (BSs), moored buoy BSs in B-UWANs experience motion responses due to wave loads under environmental conditions, posing unique challenges to the handover process. This study examines how BS motion affects handover decision errors, which arise when AUVs incorrectly initiate handovers to unintended BSs due to BS motion. By utilizing the AUV-BS distance as a handover triggering parameter, our analysis reveals a significant increase in decision errors within the overlapping regions when both the current and target BSs are in motion, especially when moving in the same direction. In addition, these errors intensify with the magnitude of BS motion and are exacerbated by smaller BS network radii. Based on these simulation results, we present an analytical framework that not only measures the influence of BS motion on the AUV-BS distance but also provides strategic insights for refining underwater handover protocols, thereby enhancing operational reliability and service continuity in B-UWANs.

BACKGROUND: Surgical handover is associated with a significant risk of care failures. Existing research displays methodological deficiencies and little consensus on the outcomes that should be used to evaluate interventions in this area. This paper reports a protocol to develop a core outcome set (COS) to support standardisation, comparability, and evidence synthesis in future studies of surgical handover between doctors.
METHODS: This study adheres to the Core Outcome Measures in Effectiveness Trials (COMET) initiative guidance for COS development, including the COS-Standards for Development (COS-STAD) and Reporting (COS-STAR) recommendations. It has been registered prospectively on the COMET database and will be led by an international steering group that includes surgical healthcare professionals, researchers, and patient and public partners. An initial list of reported outcomes was generated through a systematic review of interventions to improve surgical handover (PROSPERO: CRD42022363198). Findings of a qualitative evidence synthesis of patient and public perspectives on handover will augment this list, followed by a real-time Delphi survey involving all stakeholder groups. Each Delphi participant will then be invited to take part in at least one online consensus meeting to finalise the COS.
BACKGROUND: This study was approved by the Royal College of Surgeons in Ireland (RCSI) Research Ethics Committee (202309015, 7th November 2023). Results will be presented at surgical scientific meetings and submitted to a peer-reviewed journal. A plain English summary will be disseminated through national websites and social media. The authors aim to integrate the COS into the handover curriculum of the Irish national surgical training body and ensure it is shared internationally with other postgraduate surgical training programmes. Collaborators will be encouraged to share the findings with relevant national health service functions and national bodies.
CONCLUSIONS: This study will represent the first published COS for interventions to improve surgical handover, the first use of a real-time Delphi survey in a surgical context, and will support the generation of better-quality evidence to inform best practice.

The AUD2IT-algorithm is a tool to structure the data, which is collected during an emergency treatment. The goal is on the one hand to structure the documentation of the data and on the other hand to give a standardised data structure for the report during handover of an emergency patient. AUD2IT-algorithm was developed to provide residents a documentation aid, which helps to structure the medical reports without getting lost in unimportant details or forgetting important information. The sequence of anamnesis, clinical examination, considering a differential diagnosis, technical diagnostics, interpretation and therapy is rather an academic classification than a description of the real workflow. In a real setting, most of these steps take place simultaneously. Therefore, the application of the AUD2IT-algorithm should also be carried out according to the real processes. A big advantage of the AUD2IT-algorithm is that it can be used as a structure for the entire treatment process and also is entirely usable as a handover protocol within this process to make sure, that the existing state of knowledge is ensured at each point of a team-timeout. PR-E-(AUD2IT)-algorithm makes it possible to document a treatment process that, in principle, does not have to be limited to the field of emergency medicine. Also, in the outpatient treatment the PR-E-(AUD2IT)-algorithm could be used and further developed. One example could be the preparation and allocation of needed resources at the general practitioner. The algorithm is a standardised tool that can be used by healthcare professionals of any level of training. It gives the user a sense of security in their daily work.

A Hybrid LiFi and WiFi network (HLWNet) integrates the rapid data transmission capabilities of Light Fidelity (LiFi) with the extensive connectivity provided by Wireless Fidelity (WiFi), resulting in significant benefits for wireless data transmissions in the designated area. However, the challenge of decision-making during the handover process in HLWNet is made more complex due to the specific characteristics of electromagnetic signals\' line-of-sight transmission, resulting in a greater level of intricacy compared to previous heterogeneous networks. This research work addresses the problem of handover decisions in the Hybrid LiFi and WiFi networks and treats it as a binary classification problem. Consequently, it proposes a handover method based on a deep neural network (DNN). The comprehensive handover scheme incorporates two sets of neural networks (ANN and DNN) that utilize input factors such as channel quality and the mobility of users to enable informed decisions during handovers. Following training with labeled datasets, the neural-network-based handover approach achieves an accuracy rate exceeding 95%. A comparative analysis of the proposed scheme against the benchmark reveals that the proposed method considerably increases user throughput by approximately 18.58% to 38.5% while reducing the handover rate by approximately 55.21% to 67.15% compared to the benchmark artificial neural network (ANN); moreover, the proposed method demonstrates robustness in the face of variations in user mobility and channel conditions.

Multi-layer networks which consist of high-frequency cells and low-frequency cells in the same coverage area, can ensure capacity and coverage simultaneously. However, the existing handover algorithms in multi-layer networks result in the waste of spectrum resources. In this paper, we propose a new handover algorithm to address this gap. To ensure coverage and capacity, the proposed algorithm utilizes inter-frequency handover based on coverage and user throughput, encourages inter-frequency handover but suppresses intra-frequency handover. We provide a theoretical basis for this algorithm, whose superior performance has been verified by our simulations. Compared with the traditional algorithms, the proposed algorithm balances the load ratio between high-frequency cells and low-frequency cells from 30/90 to 60/80; Meanwhile, the proposed algorithm increases user throughput by at least 54.3% for the handover users; Moreover, the proposed algorithm increases the average signal interference plus noise ratio by about 1.5 dB for the high-frequency cells and 5 dB for the low-frequency cells, which gives rise to the increase in system capacity for 10.5% and 11.57% for downlink and uplink, respectively; Besides, the proposed algorithm decreases call blocking ratio by 38% and end-to-end delay by 5.82%.

The present work aims to map the available scientific evidence on the benefits of using the ISBAR tool in the nursing care of acutely ill adult patients\' handover in an emergency department context. To this end, a scoping review was conducted, according to the guidelines proposed by the Joanna Briggs Institute (JBI), to answer the following research question: \"What are the benefits of using the ISBAR tool in the nursing care of acutely ill adult patients\' handover in an emergency department context?\" The bibliographic search was carried out during August and September 2023 in the following electronic databases: CINAHL Complete; MEDLINE Complete; Cochrane Central Register of Controlled Trials; Cochrane Database of Systematic Reviews; and Cochrane Methodology Register. Only works published between 2013 and 2023 were deemed fit for inclusion. All the included studies (9) show that ISBAR methodology, as a standardized tool for transferring nursing care in the emergency service, allows for a safe, clear, and concise transition of nursing care. The benefits relate to patient and professional safety, continuity, and quality of care, as well as patient and professional comfort, with health gains.

UNASSIGNED: Patient handover is a crucial transition requiring a high level of coordination and communication. In the BC Children\'s Hospital (BCCH) pediatric intensive care unit (PICU), 10 adverse events stemming from issues that should have been addressed at the operating room (OR) to PICU handover were reported into the patient safety learning system (PSLS) within 1 year. We aimed to undertake a quality improvement project to increase adherence to a standardized OR to PICU handover process to 100% within a 6-month time frame. In doing so, the secondary aim was to reduce adverse events by 50% within the same 6-month period.
UNASSIGNED: The model for improvement and a Plan, Do, Study, Act method of quality improvement was used in this project. The adverse events were reviewed to identify root causes. The findings were reviewed by a multidisciplinary inter-departmental group comprised of members from surgery, anesthesia, and intensive care. Issues were batched into themes to address the most problematic parts of handover that were contributing to risk.
UNASSIGNED: A bedside education campaign was initiated to familiarize the team with an existing handover standard. The project team then formulated a new simplified visual handover tool with the mnemonic \"PATHQS\" where each letter denoted a step addressing a theme that had been noted in the pre-intervention work as contributing to adverse events.
UNASSIGNED: Adherence to standardized handover at 6 months improved from 69% to 92%. This improvement was sustained at 12 months and 3 years after the introduction of PATHQS. In addition, there were zero PSLS events relating to handover at 6 and 12 months, with only one filed by 36 months. Notably, staff self-reporting of safety concerns during handover reduced from 69% to 13% at 6 months and 0% at 3 years. The PATHQS tool created in this work also spread to six other units within the hospital as well as to one adult teaching hospital.
UNASSIGNED: A simplified handover tool built collaboratively between departments can improve the quality and adherence of OR to PICU handover and improve patient safety. Simplification makes it adaptable and applicable in many different healthcare settings.

This article was migrated. The article was marked as recommended. Poor standards of handover threaten patient safety and continuity of care, contributing significantly to morbidity and mortality. Handover practices has risen to the forefront of the patient safety agenda, with a call to develop and implement undergraduate handover modules into undergraduate healthcare education. Recent systematic reviews demonstrate a common failure of educational interventions to demonstrate a theoretical and pedagogical framework underpinning the delivery of education and method of assessment. The authors developed and piloted a multi-disciplinary evidence-based undergraduate handover training program to health care students studying at a UK university. The intervention was designed based on underpinning educational theories. It has been developed in a manner that supports dissemination and replication, with a model that is cost effective. The intervention was designed to assess learner reaction, attitudes and confidence, and knowledge and skills. This was achieved through a pre- and post-intervention attitude questionnaire, and an externally validated pre- and post-intervention knowledge assessment. 46 undergraduate students participated, with a statistically significant increase in self-reported attitudes (p < 0.001) and knowledge (p < 0.001) following the handover intervention. Students participated from the disciplines of medicine, adult nursing, pharmacy, mental health nursing, paramedic practice and operating department practioners. This intervention serves as a significant resource for those looking to develop local interventions and stands as a truly multi-disciplinary approach to handover education, mirroring the clinical reality. The introduction of this handover intervention immediately improves the attitudes, knowledge and skills of undergraduate healthcare students. Future work should sample beyond the selected 6 professions, investigating the transference of outcomes to the workplace, as well as the impact on patient safety.

Despite the extensive volume of research published on checklists in the intensive care unit (ICU), no review has been published on the broader role of checklists within the intensive care unit, their implementation and validation, and the recommended clinical context for their use. Accordingly, a scoping review was necessary to map the current literature and to guide future research on intensive care checklists. This review focuses on what checklists are currently used, how they are used, process of checklist development and implementation, and outcomes associated with checklist use.
A systematic search of MEDLINE (Ovid), Embase, Scopus, and Google Scholar databases was conducted, followed by a grey literature search. The abstracts of the identified studies were screened. Full texts of relevant articles were reviewed, and the references of included studies were subsequently screened for additional relevant articles. Details of the study characteristics, study design, checklist intervention, and outcomes were extracted.
Our search yielded 2046 studies, of which 167 were selected for further analysis. Checklists identified in these studies were categorised into the following types: rounding checklists; delirium screening checklists; transfer and handover checklists; central line-associated bloodstream infection (CLABSI) prevention checklists; airway management checklists; and other. Of 72 significant clinical outcomes reported, 65 were positive, five were negative, and two were mixed. Of 122 significant process of care outcomes reported, 114 were positive and eight were negative.
Checklists are commonly used in the intensive care unit and appear in many clinical guidelines. Delirium screening checklists and rounding checklists are well implemented and validated in the literature. Clinical and process of care outcomes associated with checklist use are predominantly positive. Future research on checklists in the intensive care unit should focus on establishing clinical guidelines for checklist types and processes for ongoing modification and improvements using post-intervention data.

UNASSIGNED: Effective documentation and transfer of clinical information are vital for the continuity of care, patient safety, and maintaining medico-legal records, as outlined by the Royal College of Surgeons \"Safe Handover: Guidance from the Working Time Directive working party\". Our elective surgery weekend team cross-covers both Colorectal and Upper Gastrointestinal surgical specialties across multiple wards, which poses a significant challenge. The aim of this study was to improve the documentation of patients\' weekend plans through the introduction of a weekend handover proforma.
UNASSIGNED: We reviewed the weekend plans of 199 patients overall. 41 records were initially reviewed over a 2-week period. The surgical multidisciplinary team was then surveyed to establish the need for an improved weekend handover. Following this, a weekend handover proforma was introduced as part of the Friday ward round and education on the expectations were provided at a local Surgery Clinical Governance meeting. The documentation of the weekend plan was reviewed for 158 patients over a 6-week period and a post-intervention survey was disseminated.
UNASSIGNED: The preliminary survey highlighted concerns for delayed discharges and patient safety over the weekend, with 88.2% of respondents agreeing a weekend handover proforma would be beneficial. The initial data confirmed inadequate documentation of diagnosis (19.5%), operation/procedure (28.1%), and weekend plans for blood tests (19.5%), discharge planning (2.4%), diet (46.3%), antibiotics (19.5%), intravenous (IV) fluids (22.0%), mobility (19.5%) and drain/wound care (37.5%). After education and implementing a weekend handover proforma, these results increased for documentation of diagnosis (61.2%), operation/procedure (83.2%), blood tests (59.7%), and discharge planning (85.8%). However, there was little improvement in diet (53.0%) and no improvement in the weekend plans for antibiotics (14.2%), IV fluids (17.2%), mobility (14.9%) and drain/wound care (20.2%). The post-intervention survey showed an improvement across all areas, notably continuity of care and patient safety, with 95.5% of individuals finding the weekend handover proforma aided in patient care over the weekend.
UNASSIGNED: Education of the ward team and implementation of a weekend handover proforma resulted in a marked improvement in the documentation of patients\' weekend plans, which is essential to ensure the continuation of safe and effective patient care.
