Implementing human factors in anaesthesia: guidance for clinicians, departments and hospitals: Guidelines from the Difficult Airway Society and the Association of Anaesthetists: Guidelines from the Difficult Airway Society and the Association of Anaesthetists.

Human factors is an evidence-based scientific discipline used in safety critical industries to improve safety and worker well-being. The implementation of human factors strategies in anaesthesia has the potential to reduce the reliance on exceptional personal and team performance to provide safe and high-quality patient care. To encourage the adoption of human factors science in anaesthesia, the Difficult Airway Society and the Association of Anaesthetists established a Working Party, including anaesthetists and operating theatre team members with human factors expertise and/or interest, plus a human factors scientist, an industrial psychologist and an experimental psychologist/implementation scientist. A three-stage Delphi process was used to formulate a set of 12 recommendations: these are described using a 'hierarchy of controls' model and classified into design, barriers, mitigations and education and training strategies. Although most anaesthetic knowledge of human factors concerns non-technical skills, such as teamwork and communication, human factors is a broad-based scientific discipline with many other additional aspects that are just as important. Indeed, the human factors strategies most likely to have the greatest impact are those related to the design of safe working environments, equipment and systems. While our recommendations are primarily provided for anaesthetists and the teams they work with, there are likely to be lessons for others working in healthcare beyond the speciality of anaesthesia.

Human factors in anaesthesia: a narrative review.

Healthcare relies on high levels of human performance, as described by the 'human as the hero' concept. However, human performance varies and is recognised to fall in high-pressure situations, meaning that it is not a reliable method of ensuring safety. Other safety-critical industries embed human factors principles into all aspects of their organisations to improve safety and reduce reliance on exceptional human performance; there is potential to do the same in anaesthesia. Human factors is a broad-based scientific discipline which aims to make it as easy as possible for workers to do things correctly. The human factors strategies most likely to be effective are those which 'design out' the chance of an error or adverse event occurring. When errors or adverse events do happen, barriers are in place to trap them and reduce the risk of progression to patient and/or worker harm. If errors or adverse events are not trapped by these barriers, mitigations are in place to minimise the consequences. Non-technical skills form an important part of human factors barriers and mitigation strategies and include: situation awareness; decision-making; task management; and team working. Human factors principles are not a substitute for proper investment and appropriate staffing levels. Although applying human factors science has the potential to save money in the long term, its proper implementation may require investment before reward can be reaped. This narrative review describes what is known about human factors in anaesthesia to date.

Ergonomics in the anaesthetic workplace: Guideline from the Association of Anaesthetists.

Ergonomics in relation to anaesthesia is the scientific study of the interaction between anaesthetists and their workspace environment in order to promote safety, performance and well-being. The foundation for avoiding pain or discomfort at work is to adopt and maintain a good posture, whether sitting or standing. Anaesthetists should aim to keep their posture as natural and neutral as possible. The successful practice of anaesthesia relies on optimisation of ergonomics and lack of attention to detail in this area is associated with impaired performance. The anaesthetic team should wear comfortable clothing, including appropriately-sized personal protective equipment where necessary. Temperature, humidity and light should be adequate at all times. The team should comply with infection prevention and control guidelines and monitoring as recommended by the Association of Anaesthetists. Any equipment or machinery that is mobile should be positioned where it is easy to view or reach without having to change the body or head position significantly when interacting with it. Patients who are supine should, whenever possible, be raised upwards to limit the need to lean towards them. Any item required during a procedure should be positioned on trays or trolleys that are close to the dominant hand. Pregnancy affects the requirements for standing, manually handling, applying force when operating equipment or moving machines and the period over which the individual might have to work without a break. Employers have a duty to make reasonable adjustments to accommodate disability in the workplace. Any member of staff with a physical impairment needs to be accommodated and this includes making provision for a wheelchair user who needs to enter the operating theatre and perform their work.

Fire safety and emergency evacuation guidelines for intensive care units and operating theatres: for use in the event of fire, flood, power cut, oxygen supply failure, noxious gas, structural collapse or other critical incidents: Guidelines from the Association of Anaesthetists and the Intensive Care Society.

The need to evacuate an ICU or operating theatre complex during a fire or other emergency is a rare event but one potentially fraught with difficulty: Not only is there a risk that patients may come to harm but also that staff may be injured and unable to work. Designing newly-built or refurbished ICUs and operating theatre suites is an opportunity to incorporate mandatory fire safety features and improve the management and outcomes of such emergencies: These include well-marked manual fire call points and oxygen shut off valves (area valve service units); the ability to isolate individual zones; multiple clear exit routes; small bays or side rooms; preference for ground floor ICU location and interconnecting routes with operating theatres; separate clinical and non-clinical areas. ICUs and operating theatre suites should have a bespoke emergency evacuation plan and route map that is readily available. Staff should receive practical fire and evacuation training in their clinical area of work on induction and annually as part of mandatory training, including 'walk-through practice' or simulation training and location of manual fire call points and fire extinguishers, evacuation routes and location and operation of area valve service units. The staff member in charge of each shift should be able to select and operate fire extinguishers and lead an evacuation. Following an emergency evacuation, a network-wide response should be activated, including retrieval and transport of patients to other ICUs if needed. A full investigation should take place and ongoing support and follow-up of staff provided.

The Anaesthesia Case Report (ACRE) checklist: a tool to promote high-quality reporting of cases in peri-operative practice.

Case reports have fulfilled an important role in the development of anaesthesia and continue to be highly relevant to modern practice. Despite this, they are sometimes criticised for being insufficiently rigorous to meaningfully inform clinical practice or research design. Reporting checklists are a useful tool to improve rigour in research and, although case report checklists have previously been developed, no existing checklist focuses on the peri-operative setting. In order to address the need for a case reports checklist that better accommodates peri-operative care, we used an established tool as the basis for developing the 12-item Anaesthesia Case Report checklist. This was refined using an iterative approach through feedback from journal editors with experience of handling case reports, patient and public involvement, and trialling its use on Anaesthesia Reports submissions. The Anaesthesia Case Report checklist differs from existing checklists by aligning with peri-operative practice; it places less emphasis on making diagnoses and focuses on the way in which clinical challenges, for example, related to the patient's comorbidities or operative interventions, are addressed. Adopting a standardised approach to the content of case reports presents clear benefits to authors, editors and peer reviewers through streamlining the processes involved in writing and publication. The Anaesthesia Case Report checklist provides a pragmatic framework for comprehensive and transparent reporting. We hope it will facilitate the authorship of high-quality case reports with the potential to further improve the quality and safety of peri-operative care.

Intranasal dexmedetomidine for sedation in children; a review.

Dexmedetomidine is an α2 adrenoreceptor agonist that may be administered by the intranasal route as a sole sedative agent in children. It is odourless, colourless and tasteless and is formulated in a concentration of 100µg.ml-1. We performed a review of published randomised controlled trials in order to determine the efficacy of intranasal dexmedetomidine for sedation in children. Fourteen trials were eligible for inclusion in the review and contained a total of 1809 patients ranging in age from one month to 14 years. Intranasal dexmedetomidine was administered in a dose range of 1-4µg.kg-1 and was compared with various other sedatives. Dexmedetomidine was administered by either drops or a mucosal atomiser device. The procedures ranged from non-painful examinations such as magnetic resonance imaging scans and transthoracic echocardiography to painful procedures such as dentistry and venous cannulation. Administration of 2µg.kg-1 appears to be the optimal dose.

The influence of first author sex on acceptance rates of submissions to Anaesthesia Cases.

More than 50% of medical students and 45% of practising doctors are female in the UK. In the specialty of anaesthesia, 32% of consultants are female. However, compared with males, females are under-represented as authors of articles published in high-impact journals. We investigated the proportion of female first authors by examining the case reports submitted to Anaesthesia Cases since its inception in 2013. We defined authors by their sex (male or female), that is, biological characteristics, rather than their gender. There were a total of 802 submissions to Anaesthesia Cases over 4.5 years. Sixteen submissions were excluded and of the remaining 786 submissions, 279 were accepted and 507 rejected, an acceptance rate of 35.5%. Twenty (2.5%) authors' sex could not be identified. The overall proportion of female first authors was 37.1%. The proportion of female first authors of accepted case reports was 42.1% and females were first authors of rejected case reports in 34.4%. We found that, compared with previous studies on female sex and gender bias in publishing, there was a relatively high proportion of female first authors publishing in Anaesthesia Cases and female first authors were more likely to be accepted than male first authors. Authorship is considered to reflect career success and there continues to be sex/gender inequity that must be tackled at all levels, from application to medical school, through research funding, journals and Editorial Boards.
