Prescription Of analgesia in Emergency Medicine (POEM): a multicentre observational survey of pain relief in patients presenting with an isolated limb fracture and/or dislocation

Background: Acute pain is one of the most commonly cited reasons for attendance to the emergency department (ED), and the Royal College of Emergency Medicine (RCEM) Best Practice Guideline (2014) acknowledged that the current management of acute pain in UK EDs is inadequate and has a poor evidence base. Methods: The Prescription Of analgesia in Emergency Medicine (POEM) survey is a cross-sectional observational survey of consecutive patients presenting to 12 National Health Service (NHS) EDs with limb fracture and/or dislocation in England and Scotland and was carried out between 2015 and 2017. The primary outcome was to assess the adequacy of pain management in the ED against the recommendations in the RCEM Best Practice Guidelines. Results: In all, 8346 patients were identified as attending the ED with a limb fracture and/or dislocation but adherence to RCEM guidelines could only be evaluated for the 4160 (49.8%) patients with a recorded pain score. Of these, 2409/4160 (57.9%) patients received appropriate pain relief, but only 1347 patients were also assessed within 20 minutes of their arrival in the ED. Therefore, according to the RCEM guidelines, only 16.1% (1347/8346) of all patients were assessed and had satisfactory pain management in the ED. Conclusions: The POEM survey has identified that pain relief for patients with an isolated limb fracture remains inadequate when strictly compared to the RCEM Best Practice Guidelines. However, we have found that some patients receive analgesia despite having no pain score recorded, while other analgesic modalities are provided that are not currently encompassed by the Best Practice Guidelines. Future iterations of these guidelines may wish to encompass the breadth of available modalities of pain relief and the whole patient journey. In addition, more work is needed to improve timely and repeated assessment of pain and its recording, which has been better achieved in some EDs than others

Finding voices: a survey of young people's experiences of the ED.

Mental health presentations in young people are increasing. Recurrence of self-harm (SH) presentations is common and of great concern since self-harm is known to be a risk factor for suicide. Previous reports suggest that the ED experience for this group is poor. A study was carried out at the Royal Berkshire NHS Foundation Trust. The objective was to pilot new and existing measures to capture the perceived needs and expectations of young people attending ED following SH compared with those attending with suspected fractures (SFs). Young people were approached to complete a questionnaire as they arrived in ED and again before they left. Questionnaires were a combination of pre-existing tools as well as piloting novel questions specific to the ED where no suitable tool previously existed. Satisfaction with the ED treatment was measured along with reattendance up to one year later. The survey was started in 2019 and suspended in March 2020 at the outset of the COVID-19 pandemic and subsequently closed, having screened 917 and recruited 104 adolescents. All the measures showed satisfactory psychometric properties with internal consistencies (alpha) of over 0.75. The two patient groups differed at baseline: it was found that the SH group had lower mood on the Short Mood and Feelings Questionnaire (p<0.001) and scored more highly on the Borderline Personality Features Scale for Children than the SF group (p<0.001) but the expectations of care across both groups was similar. Using the experience measures, the SH group was less satisfied with treatment than the SF group (p=0.0263). Our findings underline the similarities between the two groups in terms of their expectations of care. Terminating the study early at the outset of the COVID-19 pandemic has precluded any further firm conclusions to be drawn. Further research is needed

Prescription Of analgesia in Emergency Medicine (POEM) secondary analysis: an observational multicentre comparison of pain relief provided to adults and children with an isolated limb fracture and/or dislocation

Background: Acute pain is a common reason for emergency department (ED) attendance. Royal College of Emergency Medicine (RCEM) pain management audits have shown national variation and room for improvement. Previous evidence suggests that children receive less satisfactory pain management than adults. Methods: Prescription of analgesia in emergency medicine is a cross-sectional observational study of consecutive patients presenting to 12 National Health Service EDs with an isolated long bone fracture and/ or dislocation, and was carried out between 2015 and 2017. Using the recommendations in the RCEM Best Practice Guidelines, pain management in ED was assessed for differences of age (adults vs children) and hospital type (children’s vs all patients). Results: From the total 8346 patients, 38% were children (median age 8 years). There was better adherence to the RCEM guidance for children than adults (24% (766/3196) vs 11% (579/5123)) for the combined outcome of timely assessment, pain score and appropriate analgesia. In addition, children were significantly more likely than adults to receive analgesia appropriate to the pain score (of those with a recorded pain score 67% (1168/1744) vs 52% (1238/2361)). Children’s hospitals performed much better across all reported outcomes compared with general hospitals. Conclusions: In contrast to previous studies, children with a limb fracture/dislocation are more likely than adults to have a pain score documented and to receive appropriate analgesia. Unexpectedly, children’s EDs performed better than general EDs in relation to timely and appropriate analgesia but the reasons for this are not apparent from the present study

Improving the accuracy of emergency department clinicians in detecting SARS-COV-2 on chest X-rays using a bespoke virtual training platform

Background: During and after the COVID pandemic, online learning became a key component in most undergraduate and post-graduate training. The non-specific symptoms of SARS-CoV-2 and limitations of available diagnostic tests can make it difficult to detect and diagnose in acute care settings. Accurate identification of SARS-CoV-2 related changes on chest x-ray (CXR) by frontline clinicians involved in direct patient care in the Emergency Department (ED) is an important skill. We set out to measure the accuracy of ED clinicians in detecting SARS-CoV-2 changes on CXRs and assess whether this could be improved using an online learning platform. Methods: Baseline reporting performance of a multi-centre cohort of ED clinicians with varying experience was assessed via the Report and Image Quality Control (RAIQC) online platform. Emergency Medicine clinicians working in EDs across five hospitals in the Thames Valley Emergency medicine Research Network (TaVERN) region were recruited over a six-month period. An image bank was created containing both SARS-CoV-2 and non- SARS-CoV-2 pathological findings. Radiological ground truth diagnosis was established by thoracic radiologists and corroborated by RT- PCR results. Participants then undertook an online training module with performance re-assessed. Diagnostic accuracy and speed of X-ray reporting was assessed before and after training in 3 subgroups: Consultants, Junior Doctors and Nurses. Results: 90 clinicians undertook pre-training assessment and 56 undertook post training assessment. There was an overall improved reporting accuracy for participants who undertook both pre and post training assessments from (44.0±10.5%) to 57.4% (±9.39)% (p < 0.001). The sensitivity for recognition of SARS-CoV-2 improved from 64.8 to 76.8%. Conclusion: ED clinicians show moderate baseline accuracy in the identification of SARS-CoV-2 related changes on CXR. Accuracy and speed can be improved by online training

Early Computed Tomography Coronary Angiography and Preventative Treatment in Patients with Suspected Acute Coronary Syndrome A secondary analysis of the RAPID-CTCA trial

BackgroundComputed tomography coronary angiography (CTCA) offers detailed assessment of the presence of coronary atherosclerosis and helps guide patient management. We investigated influences of early CTCA on the subsequent use of preventative treatment in patients with suspected acute coronary syndrome.MethodsIn this secondary analysis of a multicentre randomised controlled trial of early CTCA in intermediate-risk patients with suspected acute coronary syndrome, prescription of aspirin, P2Y12 receptor antagonist, statin, renin–angiotensin system blocker, and beta-blocker therapies from randomisation to discharge were compared within then between those randomised to early CTCA or to standard of care only. Effects of CTCA findings on adjustment of these therapies were further examined.ResultsIn 1743 patients (874 randomised to early CTCA and 869 to standard of care only), prescription of P2Y12 receptor antagonist, dual antiplatelet, and statin therapiesincreased more in the early CTCA group (between-group difference: 4.6% (95% confidence interval, 0.3 to 8.9), 4.5% (95% confidence interval, 0.2 to 8.7), and 4.3% (95% confidence interval, 0.2 to 8.5), respectively), whereas prescription of other preventative therapies increased by similar extent in both study groups. Amongst patients randomised to early CTCA, there were additional increments of preventative treatment in those with obstructive coronary artery disease and higher rates of 6 reductions in antiplatelet and beta-blocker therapies in those with normal coronary arteries.ConclusionsPrescription patterns of preventative treatment varied during index hospitalisation in patients with suspected acute coronary syndrome. Early CTCA facilitated targeted individualisation of these therapies based on the extent of coronary artery disease.<br/

Early computed tomography coronary angiography in adults presenting with suspected acute coronary syndrome:the RAPID-CTCA RCT

Abstract Background Acute coronary syndrome is a common medical emergency. The optimal strategy to investigate patients who are at intermediate risk of acute coronary syndrome has not been fully determined. Objective To investigate the role of early computed tomography coronary angiography in the investigation and treatment of adults presenting with suspected acute coronary syndrome. Design A prospective, multicentre, open, parallel-group randomised controlled trial with blinded end-point adjudication. Setting Thirty-seven hospitals in the UK. Participants Adults (aged ≥ 18 years) presenting to the emergency department, acute medicine services or cardiology department with suspected or provisionally diagnosed acute coronary syndrome and at least one of the following: (1) a prior history of coronary artery disease, (2) a cardiac troponin level > 99th centile and (3) an abnormal 12-lead electrocardiogram. Interventions Early computed tomography coronary angiography in addition to standard care was compared with standard care alone. Participants were followed up for 1 year. Main outcome measure One-year all-cause death or subsequent type 1 (spontaneous) or type 4b (stent thrombosis) myocardial infarction, measured as the time to such event adjudicated by two cardiologists blinded to the computerised tomography coronary angiography (CTCA) arm. Cost-effectiveness was estimated as the lifetime incremental cost per quality-adjusted life-year gained. Results Between 23 March 2015 and 27 June 2019, 1748 participants [mean age 62 years (standard deviation 13 years), 64% male, mean Global Registry Of Acute Coronary Events score 115 (standard deviation 35)] were randomised to receive early computed tomography coronary angiography (n = 877) or standard care alone (n = 871). The primary end point occurred in 51 (5.8%) participants randomised to receive computed tomography coronary angiography and 53 (6.1%) participants randomised to receive standard care (adjusted hazard ratio 0.91, 95% confidence interval 0.62 to 1.35; p = 0.65). Computed tomography coronary angiography was associated with a reduced use of invasive coronary angiography (adjusted hazard ratio 0.81, 95% confidence interval 0.72 to 0.92; p = 0.001) but no change in coronary revascularisation (adjusted hazard ratio 1.03, 95% confidence interval 0.87 to 1.21; p = 0.76), acute coronary syndrome therapies (adjusted odds ratio 1.06, 95% confidence interval 0.85 to 1.32; p = 0.63) or preventative therapies on discharge (adjusted odds ratio 1.07, 95% confidence interval 0.87 to 1.32; p = 0.52). Early computed tomography coronary angiography was associated with longer hospitalisations (median increase 0.21 days, 95% confidence interval 0.05 to 0.40 days) and higher mean total health-care costs over 1 year (£561 more per patient) than standard care. Limitations The principal limitation of the trial was the slower than anticipated recruitment, leading to a revised sample size, and the requirement to compromise and accept a larger relative effect size estimate for the trial intervention. Future work The potential role of computed tomography coronary angiography in selected patients with a low probability of obstructive coronary artery disease (intermediate or mildly elevated level of troponin) or who have limited access to invasive cardiac catheterisation facilities needs further prospective evaluation. Conclusions In patients with suspected or provisionally diagnosed acute coronary syndrome, computed tomography coronary angiography did not alter overall coronary therapeutic interventions or 1-year clinical outcomes, but it did increase the length of hospital stay and health-care costs. These findings do not support the routine use of early computed tomography coronary angiography in intermediate-risk patients with acute chest pain

HiSNAP trial—a multicentre, randomised, open-label, blinded end point, safety and efficacy trial of conventional (300 mg/kg) versus higher doses of acetylcysteine (450 mg/kg and 600 mg/kg) in patients with paracetamol overdose in the UK:Study protocol

Introduction: In overdose, a larger proportion of paracetamol (acetaminophen) is converted in the liver to the toxic metabolite N-acetyl-p-benzoquinone imine (NAPQI). Glutathione (GSH) is the endogenous antioxidant that protects cells from NAPQI-induced injury. In overdose, GSH stores may become depleted, leaving NAPQI free to produce liver damage. Acetylcysteine (NAC) helps prevent paracetamol toxicity by replenishing liver GSH. This protective effect of NAC produces specific metabolites in the circulation. Currently, regardless of the paracetamol dose ingested, patients in the United Kingdom receive a dose of NAC based only on their weight. Basic pharmacology, mathematical modelling and observational studies suggests that this dose may be insufficient in some patients (particularly those taking a large overdose).Methods and analysis: A multi-centre trial, taking place across several hospitals in Scotland, UK, within Emergency Departments and Acute Medical Units. Recruitment commenced 19 Feb 2024, and is anticipated to run for approximately two years. This is a three-group dose finding trial, in which participants are assigned in a 1:1:1 ratio to either standard NAC (300mg/kg), or higher doses of 450mg/kg (Group 1) and 600mg/kg (Group 2). The primary outcome is the proportion of paracetamol metabolites in the circulation that are directly produced by GSH/NAC detoxification of NAPQI. A higher proportion of these metabolites will indicate that the additional NAC is reducing the amount of toxic paracetamol metabolites in the body. The study will first test the primary outcome on the HiSNAP Group 2 against Standard NAC; only if that is significant, will HiSNAP Group 1 be tested against Standard NAC.Ethics and dissemination: The HiSNAP trial has been approved by East Midlands (Derby) Research Ethics Committee (reference 23/EM/0129), NHS Lothian Research and Development department, and the MHRA. Results will be disseminated by peer-reviewed publication, conferences, and linked on isrctn.com
