Clinical handover within the emergency care pathway and the potential risks of clinical handover failure (ECHO) : primary research

Background and objectives: Handover and communication failures are a recognised threat to patient safety. Handover in emergency care is a particularly vulnerable activity owing to the high-risk context and overcrowded conditions. In addition, handover frequently takes place across the boundaries of organisations that have different goals and motivations, and that exhibit different local cultures and behaviours. This study aimed to explore the risks associated with handover failure in the emergency care pathway, and to identify organisational factors that impact on the quality of handover. Methods: Three NHS emergency care pathways were studied. The study used a qualitative design. Risks were explored in nine focus group-based risk analysis sessions using failure mode and effects analysis (FMEA). A total of 270 handovers between ambulance and the emergency department (ED), and the ED and acute medicine were audio-recorded, transcribed and analysed using conversation analysis. Organisational factors were explored through thematic analysis of semistructured interviews with a purposive convenience sample of 39 staff across the three pathways. Results: Handover can serve different functions, such as management of capacity and demand, transfer of responsibility and delegation of aspects of care, communication of different types of information, and the prioritisation of patients or highlighting of specific aspects of their care. Many of the identified handover failure modes are linked causally to capacity and patient flow issues. Across the sites, resuscitation handovers lasted between 38 seconds and 4 minutes, handovers for patients with major injuries lasted between 30 seconds and 6 minutes, and referrals to acute medicine lasted between 1 minute and approximately 7 minutes. Only between 1.5% and 5% of handover communication content related to the communication of social issues. Interview participants described a range of tensions inherent in handover that require dynamic trade-offs. These are related to documentation, the verbal communication, the transfer of responsibility and the different goals and motivations that a handover may serve. Participants also described the management of flow of patients and of information across organisational boundaries as one of the most important factors influencing the quality of handover. This includes management of patient flows in and out of departments, the influence of time-related performance targets, and the collaboration between organisations and departments. The two themes are related. The management of patient flow influences the way trade-offs around inner tensions are made, and, on the other hand, one of the goals of handover is ensuring adequate management of patient flows. Conclusions: The research findings suggest that handover should be understood as a sociotechnical activity embedded in clinical and organisational practice. Capacity, patient flow and national targets, and the quality of handover are intricately related, and should be addressed together. Improvement efforts should focus on providing practitioners with flexibility to make trade-offs in order to resolve tensions inherent in handover. Collaborative holistic system analysis and greater cultural awareness and collaboration across organisations should be pursued

Emergency Care Handover (ECHO study) across care boundaries : the need for joint decision making and consideration of psychosocial history

Background: Inadequate handover in emergency care is a threat to patient safety. Handover across care boundaries poses particular problems due to different professional, organisational and cultural backgrounds. While there have been many suggestions for standardisation of handover content, relatively little is known about the verbal behaviours that shape handover conversations. This paper explores both what is communicated (content) and how this is communicated (verbal behaviours) during different types of handover conversations across care boundaries in emergency care. Methods: Three types of interorganisational (ambulance service to emergency department (ED) in ‘resuscitation’ and ‘majors’ areas) and interdepartmental handover conversations (referrals to acute medicine) were audio recorded in three National Health Service EDs. Handover conversations were segmented into utterances. Frequency counts for content and language forms were derived for each type of handover using Discourse Analysis. Verbal behaviours were identified using Conversation Analysis. Results: 203 handover conversations were analysed. Handover conversations involving ambulance services were predominantly descriptive (60%–65% of utterances), unidirectional and focused on patient presentation (75%–80%). Referrals entailed more collaborative talk focused on the decision to admit and immediate care needs. Across all types of handover, only 1.5%–5% of handover conversation content related to the patient's social and psychological needs. Conclusions: Handover may entail both descriptive talk aimed at information transfer and collaborative talk aimed at joint decision-making. Standardisation of handover needs to accommodate collaborative aspects and should incorporate communication of information relevant to the patient's social and psychological needs to establish appropriate care arrangements at the earliest opportunity

Resilient healthcare theory as a lens to research emergency department operations : a protocol for a scoping review

Introduction Emergency departments (EDs) are complex systems that have constant fluctuations in demand, creating mismatches with planned capacity. Despite the complexity of ED operations, quality and safety improvement are often approached in a reactive, linear and reductionist manner. There is increasing interest in adopting Resilient Healthcare (RHC) techniques based on complex systems thinking as a method for quality improvement and research in EDs. However, the evidence for this approach is still developing and it is not clear what techniques have been used so far and which are most effective. This scoping review will be conducted between March 2022 until May 2022. It seeks to examine the international literature for available reports that have adopted RHC theory to study ED operations and identify approaches used and proposed benefits. Methods and analysis The methodology for scoping reviews outlined by Arksey and O’Malley (2005) will be followed, acknowledging refinements made to the scoping review process by Levac et al (2010). The methodology consists of five steps: (1) identifying the research question; (2) identifying the relevant literature; (3) study selection; (4) charting the data; and (5) collating, summarising and reporting the results. A two-stage approach will be undertaken to synthesise and report results: (1) numerical analysis of the nature and distribution of studies (the overall number of studies, country of origin, the most studied core function of ED, type of research design); and (2) a thematic mapping of the literature. Ethics and dissemination Scoping review methodology synthesises published data and, therefore, does not require ethical approval. An article formatted in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews reporting guidance will be submitted for publication to a scientific journal. Findings will also be presented at relevant advanced practice conferences and disseminated within clinical and academic groups

An autonomous role in emergency departments.

Heart of England NHS Foundation Trust, which manages 250,000 patients in three emergency units each year, has created an advanced clinical practitioner (ACP) role to ensure that patients can be seen in a timely manner as demand for emergency services continues to rise. Advanced clinical practitioners are non-medical clinicians who eventually work autonomously at the level of middle-grade doctors and manage patients with all types of clinical presentations in the emergency department (ED). This article provides an overview of the development and benefits of the ACP role and outlines the phases of a programme for staff who wish to achieve senior clinician status in the ED

The epilepsy-associated protein TBC1D24 is required for normal development, survival and vesicle trafficking in mammalian neurons

Mutations in the Tre2/Bub2/Cdc16 (TBC)1 domain family member 24 (TBC1D24) gene are associated with a range of inherited neurological disorders, from drug-refractory lethal epileptic encephalopathy and DOORS syndrome (deafness, onychodystrophy, osteodystrophy, mental retardation, seizures) to non-syndromic hearing loss. TBC1D24 has been implicated in neuronal transmission and maturation, although the molecular function of the gene and the cause of the apparently complex disease spectrum remain unclear. Importantly, heterozygous TBC1D24 mutation carriers have also been reported with seizures, suggesting that haploinsufficiency for TBC1D24 is significant clinically. Here we have systematically investigated an allelic series of disease-associated mutations in neurons alongside a new mouse model to investigate the consequences of TBC1D24 haploinsufficiency to mammalian neurodevelopment and synaptic physiology. The cellular studies reveal that disease-causing mutations that disrupt either of the conserved protein domains in TBC1D24 are implicated in neuronal development and survival and are likely acting as loss-of-function alleles. We then further investigated TBC1D24 haploinsufficiency in vivo and demonstrate that TBC1D24 is also crucial for normal presynaptic function: genetic disruption of Tbc1d24 expression in the mouse leads to an impairment of endocytosis and an enlarged endosomal compartment in neurons with a decrease in spontaneous neurotransmission. These data reveal the essential role for TBC1D24 at the mammalian synapse and help to define common synaptic mechanisms that could underlie the varied effects of TBC1D24 mutations in neurological disease

Managing competing organizational priorities in clinical handover across organizational boundaries.

OBJECTIVES Handover across care boundaries poses additional challenges due to the different professional, organizational and cultural backgrounds of the participants involved. This paper provides a qualitative account of how practitioners in emergency care attempt to align their different individual and organizational priorities and backgrounds when handing over patients across care boundaries (ambulance service to emergency department (ED), and ED to acute medicine). METHODS A total of 270 clinical handovers were observed in three emergency care pathways involving five participating NHS organizations (two ambulance services and three hospitals). Half-day process mapping sessions were conducted for each pathway. Semi-structured interviews were carried out with 39 participants and analysed thematically. RESULTS The management of patient flow and the fulfilment of time-related performance targets can create conflicting priorities for practitioners during handover. Practitioners involved in handover manage such competing organizational priorities through additional coordination effort and dynamic trade-offs. Practitioners perceive greater collaboration across departments and organizations, and mutual awareness of each other's goals and constraints as possible ways towards more sustainable improvement. CONCLUSION Sustainable improvement in handover across boundaries in emergency care might require commitment by leaders from all parts of the local health economy to work as partners to establish a culture of integrated, patient-centred care

Confounding Factors in Targeted Degradation of Short-Lived Proteins

Targeted protein degradation has recently emerged as a novel option in drug discovery. Natural protein half-life is expected to affect the efficacy of degrading agents, but to what extent it influences target protein degradation has not been systematically explored. Using simple mathematical modeling of protein degradation, we find that the natural half-life of a target protein has a dramatic effect on the level of protein degradation induced by a degrader agent which can pose significant hurdles to screening efforts. Moreover, we show that upon screening for degraders of short-lived proteins, agents that stall protein synthesis, such as GSPT1 degraders and generally cytotoxic compounds, deceptively appear as protein-degrading agents. This is exemplified by the disappearance of short-lived proteins such as MCL1 and MDM2 upon GSPT1 degradation and upon treatment with cytotoxic agents such as doxorubicin. These findings have implications for target selection as well as for the type of control experiments required to conclude that a novel agent works as a bona fide targeted protein degrader.</p
