Summary: Hip fractures continue to be one of the most serious and costly injuries suffered by older people globally. This paper describes the development of a national hip fracture audit and summarises the first 6 years of data from the Republic of Ireland. This can help inform care, standards and outcomes of hip fracture patients. Introduction: Ireland has one of the highest standardised rates of hip fracture in the world behind northern European countries. The Irish Hip Fracture Database (IHFD) was established in 2012 to drive clinical and organisational improvements in quality and effectiveness of hip fracture care. This paper describes the progression of the IHFD between 2013 and 2018 and identifies trends and areas for improvement. Methods: The IHFD is a clinically led, web-based audit, with data collected through the national Hospital Inpatient Enquiry (HIPE) electronic system, the principal source of information from publicly funded acute hospitals in Ireland. Eligible cases are aged ≥ 60 years with hip fracture as defined by IHFD or with other specified hip fracture excluding periprosthetic fractures. As of 2015, all 16 trauma-receiving hospitals within Ireland submitted data. Demographics and adherence to six national quality standards are described. Results: A total of 17,983 cases were included in the analysis. National coverage has increased from 63% in 2013 to 99% in 2018. Demographic characteristics are unchanged, but higher levels of comorbidity are seen. Internal fixation and hemiarthroplasty are the most common modes of surgical repair with two-thirds of cases receiving spinal rather than general anaesthesia. Increasingly patients are being assessed by a geriatrician (11% in 2013 to 69% in 2018) and receive a bone health assessment (65% in 2013 to 84% in 2018). Conclusion: While some hip fracture standards have improved, further improvements are required to compare favourably internationally. Reduction of surgical delay and ensuring early mobilisation post-operatively are immediate priorities for the IHFD. [ABSTRACT FROM AUTHOR]

• Detect the moment patients transit to unresponsiveness during general anesthesia. • Importance of personalizing information on anesthetic requirements. • The usefulness of a Convolutional Network to learn the raw EEG for classification. • Our model was able to identify the transition to unresponsiveness successfully. General anesthesia is a reversible drug-induced state of altered arousal characterized by loss of responsiveness (LOR) due to brainstem inactivation. Precise identification of the LOR during the induction of general anesthesia is extremely important to provide personalized information on anesthetic requirements and could help maintain an adequate level of anesthesia throughout surgery, ensuring safe and effective care and balancing the avoidance of intraoperative awareness and overdose. So, main objective of this paper was to investigate whether a Convolutional Neural Network (CNN) applied to bilateral frontal electroencephalography (EEG) dataset recorded from patients during opioid-propofol anesthetic procedures identified the exact moment of LOR. A clinical protocol was designed to allow for the characterization of different clinical endpoints throughout the transition to unresponsiveness. Fifty (50) patients were enrolled in the study and data from all was included in the final dataset analysis. While under a constant estimated effect-site concentration of 2.5 ng/mL of remifentanil, an 1% propofol infusion was started at 3.3 mL//h until LOR. The level of responsiveness was assessed by an anesthesiologist every six seconds using a modified version of the Richmond Agitation-Sedation Scale (aRASS). The frontal EEG was acquired using a bilateral bispectral (BIS VISTA™ v2.0, Medtronic, Ireland) sensor. EEG data was then split into 5-second epochs, and for each epoch, the anesthesiologist's classification was used to label it as responsiveness (no-LOR) or unresponsiveness (LOR). All 5-second epochs were then used as inputs for the CNN model to classify the untrained segment as no-LOR or LOR. The CNN model was able to identify the transition from no-LOR to LOR successfully, achieving 97.90±0.07% accuracy on the cross-validation set. The obtained results showed that the proposed CNN model was quite efficient in the responsiveness/unresponsiveness classification. We consider our approach constitutes an additional technique to the current methods used in the daily clinical setting where LOR is identified by the loss of response to verbal commands or mechanical stimulus. We therefore hypothesized that automated EEG analysis could be a useful tool to detect the moment of LOR, especially using machine learning approaches. [ABSTRACT FROM AUTHOR]

MAGNETIC resonance ,ANESTHESIOLOGISTS ,ANESTHESIA ,SCANNING systems - Abstract
The number of anaesthetists who are involved in magnetic resonance (MR) units is increasing. Magnetic resonance systems are becoming more powerful and interventional procedures are now possible. This paper updates information relating to safety terminology, occupational exposure, reactions to gadolinium-based contrast agents and the risk of nephrogenic systemic fibrosis. Magnetic resonance examinations of patients with pacemakers are still generally contra-indicated but have been carried out in specialist centres under strictly controlled conditions. As availability of MR increases, so the education of anaesthetists, who are occasionally required to provide a service, must be considered. Anaesthesia in MR units was first described in the 1980s. Guidelines on the provision of anaesthetic services in MR units were published by the Association of Anaesthetists of Great Britain and Ireland (AAGBI) in 2002 [1]. Since then, the number of hospitals with MR units, and hence the number of patients requiring anaesthesia for MR, has increased. While the issues relating to setting up anaesthetic services in MR have not changed, there have been a number of developments that warrant this update: 1 Safety terminology and guidelines have changed. 2 MR systems utilise higher magnetic-field strengths and more open designs are available. 3 Interventional and intra-operative MR are now routine in some centres. 4 Mobile MR scanners are increasingly used to reduce waiting lists. 5 Although still generally contra-indicated, some patients with pacemakers have been scanned under strictly controlled conditions in specialist centres. 6 'MR safe' medical implants are now being produced. 7 New equipment is now available for use in MR. 8 Out-of-hours availability of MR investigations has increased. 9 Reports of allergic reactions to MR contrast media have increased. 10 Gadolinium based contrast agents (Gd-CAs) are associated with a varying degree of risk of nephrogenic systemic fibrosis in patients with impaired renal function.

Background Palliative sedation, or bringing about a state of decreased or absent awareness (unconsciousness), is one of the therapies used in end-of-life healthcare settings in order to manage refractory symptoms such as pain, dyspnoea and distress. It is intended to relieve the burden of intolerable suffering of patients who are in the process of dying. Nurses are centrally involved in the utilisation of palliative sedation in end-of-life care; however, there is minimal research available in relation to their experiences in this regard. The dearth of research prompted this study. Aim To explore the experiences of palliative care nurses in the utilisation of palliative sedation in end-of-life care. Methodology A descriptive phenomenological methodology was adopted involving unstructured interviews. A purposive sample was used of 10 palliative care nurses with at least 1 year's experience of working in a hospice setting in Ireland. The data were analysed using Colaizzi's seven-stage phenomenological method. Findings Data analysis led to the identification of four core themes: (1) information sharing, (2) timing of palliative sedation, (3) level of sedation and (4) palliative sedation as a last resort. The results indicate that the participants were generally satisfied with the processes that underpinned decisions to introduce palliative sedation. They saw it as a highly complex intervention, in part because it involved individuals with very complex conditions and symptoms. Conclusions Palliative care patients, families and the general public in Ireland need to have greater understanding of the role of palliative sedation in the treatment of refractory symptoms at the end of life.

The tragic death of an anaesthetic trainee driving home after a series of night shifts prompted a national survey of fatigue in trainee anaesthetists. This indicated that fatigue was widespread, with significant impact on trainees' health and well-being. Consultants deliver an increasing proportion of patient care resulting in long periods of continuous daytime duty and overnight on-call work, so we wished to investigate their experience of out-of-hours working and the causes and impact of work-related fatigue. We conducted a national survey of consultant anaesthetists and paediatric intensivists in the UK and Ireland between 25 June and 6 August 2018. The response rate was 46% (94% of hospitals were represented): 84% of respondents (95%CI 83.1-84.9%) contribute to a night on-call rota with 32% (30.9-33.1%) working 1:8 or more frequently. Sleep disturbance on-call is common: 47% (45.6-48.4%) typically receive two to three phone calls overnight, and 48% (46.6-49.4%) take 30 min or more to fall back to sleep. Only 15% (14.0-16.0%) reported always achieving 11 h of rest between their on-call and their next clinical duty, as stipulated by the European Working Time Directive. Moreover, 24% (22.8-25.2%) stated that there is no departmental arrangement for covering scheduled clinical duties following a night on-call if they have been in the hospital overnight. Overall, 91% (90.3-91.7%) reported work-related fatigue with over half reporting a moderate or significantly negative impact on health, well-being and home life. We discuss potential explanations for these results and ways to mitigate the effects of fatigue among consultants. [ABSTRACT FROM AUTHOR]

The Association of Anaesthetists of Great Britain and Ireland and the then Uganda Society of Anaesthesia established the Uganda Fellowship Scheme in 2006, to provide scholarships to encourage doctors to train in anaesthesia in Uganda. We conducted an evaluation of this programme using online questionnaires and face-to-face semi-structured interviews with trainees who received scholarships, as well as with senior surgeons and anaesthetists. Focus group discussions were held to assess changes in attitudes towards anaesthesia over the last 10 years. Interviews were recorded, transcribed and analysed using the constant comparative method. A total of 54 Ugandan doctors have received anaesthesia scholarships since 2006 (median funding per trainee (IQR [range]) £5520 (£5520-£6750 [£765-£9000]). There has been a four-fold increase in the number of physician anaesthetists in Uganda during this time. All those who received funding remain in the region. The speciality of anaesthesia is undergoing a dramatic transformation led by this group of motivated young anaesthetists. There is increased access to intensive care, and this has allowed surgical specialities to develop. There is greater understanding and visibility of anaesthesia, and the quality of education in anaesthesia throughout the country has improved. The Uganda Fellowship Scheme provided a relatively small financial incentive to encourage doctors to train as anaesthetists. Evaluation of the project shows a wide-ranging impact that extends beyond the initial goal of simply improving human resource capacity. Financial incentives combined with strong 'north-south' links between professional organisations can play an important role in tackling the shortage of anaesthesia providers in a low-income country and in improving access to safe surgery and anaesthesia.

Aims Anaphylaxis during anaesthesia is a rare and potentially fatal event. Adequate reporting and investigation of anaphylaxis associated with anaesthesia results in improved patient safety and outcomes. Guidelines from the Association of Anaesthetists of Great Britain and Ireland ( AAGBI) designed to improve this process were first issued in 1990 and updated in 1995, 2003 and 2008. In a setting where no formal guideline was previously in place, we compared the reporting and investigation of anaphylaxis in a large hospital before and after the introduction of the 2008 guideline. Methods A retrospective outcome audit was conducted to compare data from 12 patients referred from April 2006 to May 2008 prior to release of the 2008 AAGBI guidance, with 53 patients referred from 2008 until April 2011. Data were collected using the AAGBI Anaphylaxis Referral Form. Results There was an increase in the number of referrals for suspected anaphylaxis following implementation of the AAGBI guidance. The clinical features observed in patients were consistent with previous studies. There was improved documentation of referral to local and national databases. Most cases resulted in cancellation of surgery, and there were no patient deaths. A substantial increase in the number of patients with amoxicillin allergy was noted in the second time period, which was linked to a change in the local perioperative antibiotic policy. Conclusions Implementation of the AAGBI guidelines locally in a large hospital in 2008 resulted in an improved awareness of the importance of reporting and investigation of suspected anaphylaxis under anaesthesia. This tool was implemented coincidentally with the change in hospital antibiotic prophylaxis and enabled the cases detected to be accurately recorded and investigated. This led to a change in the hospital antibiotic policy for surgical prophylaxis. Implementation of structured guidance from a national anaesthesia organisation enhances recognition of the clinical features of anaphylaxis, increases number and completeness of referrals and more thorough immunological investigation, leading to improved patient safety during anaesthesia.

To investigate students' opinion about theoretical and clinical training in local anaesthesia at different European dental schools. A questionnaire was designed to collect information about local anaesthesia teaching. Students' opinion was quantified with five-point Likert scales. The web-based questionnaire was distributed through European Dental Students Association contacts amongst students of 25 different dental schools. Eight hundred and eighteen completed questionnaires from students of 12 dental schools were analyzed statistically. Dental schools showed a wide variation in the beginning of the theoretical teaching of local anaesthesia and the practical teaching. A preclinical training model was used by a small number of students, but these students found it a useful preparation. Many students felt insufficiently prepared when they administered their first injection in a human (17-81%). In dental schools from the UK, Ireland, Sweden and the Netherlands, this first injection is administered to a fellow dental student, whilst in the other countries the first injection is usually performed in a patient. Instruction in mandibular block anaesthesia was frequently reported (81-100%) as well as in infiltration anaesthesia of the upper and lower jaws (78-100% and 30-93% respectively). Many students expressed that they like to receive teaching in intraligamentary anaesthesia (13-70%). Other changes in the curriculum were also frequently suggested (33-100%), especially the introduction of preclinical training models and practical teaching earlier in the curriculum. Local anaesthesia teaching programmes and the rating of this teaching by dental students show a considerable variation across European dental schools. Students considered better preparation highly desirable. The variability in programmes may have implications for mobility of students between European dental schools. [ABSTRACT FROM AUTHOR]
