RESUMEN
OBJECTIVES: Given the uncertainty regarding the optimal approach for airway management for adult patients with out-of-hospital cardiac arrest (OHCA), we conducted a systematic review and meta-analysis to compare the use of supraglottic airways (SGAs) with tracheal intubation for initial airway management in OHCA. DATA SOURCES: We searched MEDLINE, PubMed, Embase, Cochrane Library, as well as unpublished sources, from inception to February 7, 2023. STUDY SELECTION: We included randomized controlled trials (RCTs) of adult OHCA patients randomized to SGA compared with tracheal intubation for initial prehospital airway management. DATA EXTRACTION: Reviewers screened abstracts, full texts, and extracted data independently and in duplicate. We pooled data using a random-effects model. We used the modified Cochrane risk of bias 2 tool and assessed certainty of evidence using the Grading Recommendations Assessment, Development, and Evaluation approach. We preregistered the protocol on PROSPERO (CRD42022342935). DATA SYNTHESIS: We included four RCTs ( n = 13,412 patients). Compared with tracheal intubation , SGA use probably increases return of spontaneous circulation (ROSC) (relative risk [RR] 1.09; 95% CI, 1.02-1.15; moderate certainty) and leads to a faster time to airway placement (mean difference 2.5 min less; 95% CI, 1.6-3.4 min less; high certainty). SGA use may have no effect on survival at longest follow-up (RR 1.06; 95% CI, 0.84-1.34; low certainty), has an uncertain effect on survival with good functional outcome (RR 1.11; 95% CI, 0.82-1.50; very low certainty), and may have no effect on risk of aspiration (RR 1.04; 95% CI, 0.94 to 1.16; low certainty). CONCLUSIONS: In adult patients with OHCA, compared with tracheal intubation, the use of SGA for initial airway management probably leads to more ROSC, and faster time to airway placement, but may have no effect on longer-term survival outcomes or aspiration events.

OBJECTIVES: Nucleic acid amplification tests (NAATs) are highly sensitive for the detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) DNA/ribosomal RNA (rRNA). Previous studies have demonstrated contamination of surfaces in sexual health clinics (SHCs) with CT/NG. False positive results can occur if patient samples are contaminated by environmental DNA/rRNA. This can have a dramatic impact on patients' lives and relationships. Previous attempts to reduce contamination, through staff training alone, have been unsuccessful. We aimed to investigate environmental contamination levels in SHCs and to assess a two-armed intervention aimed at reducing surface contamination. METHODS: Questionnaires were sent to 10 SHCs. Six clinics, with differing characteristics, were selected to participate in sample collection. Each clinic followed standardised instructions to sample surfaces using a CT/NG NAAT swab. Clinics were invited to introduce the two-armed intervention. The first arm was cleaning with a chlorine-based cleaning solution once daily. The second arm involved introducing clinic-specific changes to reduce contamination. RESULTS: 7/10 (70%) clinics completed the questionnaire. Overall, 88/263 (33%) swabs were positive for CT/NG. Clinics 1, 3 and 4 had high levels of contamination, with 28/64 (44%), 17/33 (52%) and 30/52 (58%) swabs testing positive, respectively. Clinics 2 and 6 had lower levels of contamination, with 7/46 (15%) and 6/35 (17%), respectively. 0/33 (0%) of swabs were positive at clinic 5 and this was the only clinic already using a chlorine-based solution to clean all surfaces and delivering twice-yearly clinic-specific infection control training. Following both intervention arms at clinic 1, 2/50 (4%, p<0.0001) swabs tested positive for CT/NG. Clinic 4 introduced each arm separately. After the first intervention, 13/52 (25%, p=0.003) swabs tested positive and following the second arm 4/50 (8%, p<0.0001) swabs were positive. CONCLUSIONS: Environmental contamination is a concern in SHCs. We recommend that all SHCs monitor contamination levels and, if necessary, consider using chlorine-based cleaning products and introduce clinic-specific changes to address environmental contamination.

A short-cut review of the available medical literature was carried out to establish whether elbow immobilisation is required after closed reduction of a distal radial fracture. After abstract review, six papers were found to answer this clinical question using the detailed search strategy. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these papers are tabulated. It is concluded that elbow immobilisation is not required.

BACKGROUND AND IMPORTANCE: The Canadian Association of Emergency Physicians atrial fibrillation (AF) checklist advises that emergency physicians initiate anticoagulation therapy for patients with AF or flutter who are CHADS65 positive. OBJECTIVES: The aim was to compare anticoagulation initiation rates between patients treated with and without an anticoagulation assessment pathway (the SAFE pathway). DESIGN: This was a retrospective cohort study. SETTINGS AND PARTICIPANTS: All emergency department patients were discharged home with a diagnosis of AF between June 2018 and May 2020 at two Canadian emergency departments. INTERVENTION: The SAFE pathway is a hard copy form which allows emergency physicians to document contraindications to anticoagulation, the positive components of the CHADS65 score, and details how to prescribe anticoagulation. OUTCOME MEASURES AND ANALYSIS: Trained researchers abstracted data on the use of the SAFE pathway by the presence or absence of the completed, scanned pathway in the electronic medical chart. The exposure of interest was use of this pathway. Patients were followed forward in time for 90 days by electronic medical record review to document stroke, transient ischemic attack, arterial embolism and major bleeding events. All events were independently adjudicated. Adjusted odds ratios were calculated to compare outcomes between those managed with and without the SAFE pathway. RESULTS: In total, 766 patients were included, of whom 264 were already taking anticoagulation, 166 were CHADS65 negative and 65 had a contraindication to anticoagulation, leaving 271 patients eligible for anticoagulation prescription. Among the 271 eligible patients, 137/166 managed with the SAFE pathway were initiated on anticoagulation and 24/105 managed without the SAFE pathway started anticoagulation (adjusted odds ratio 25.9; 13.1-51.2). There was no statistically significant difference in the 90-day rate of stroke or bleeding. CONCLUSION: Use of the SAFE pathway was associated with a higher rate of anticoagulation prescription.

INTRODUCTION: Poor health of sex workers continues to be a source of international concern. Sex work is frequently linked with problematic drug use and drug-dependent sex workers typically work on the street, experiencing the greatest risks to health compared with the general population. Street sex workers (SSWs) are much more likely to have experienced incidences of physical and sexual assault, increasing their risk of developing post-traumatic stress disorder (PTSD). We have developed a novel complex intervention designed to reduce illicit drug use in drug-dependent female SSWs which involves: female SSW drug treatment groups (provided by a specialist charity) in a female SSW setting (female sex worker charity premises) provided by female-only staff, PTSD care with eye movement desensitisation and reprocessing (EMDR) therapy provided by female staff from National Health Service (NHS) mental health services. METHODS AND ANALYSIS: A mixed methods study investigating the feasibility and acceptability of this intervention to inform the design of a future randomised controlled trial. The study aims to recruit up to 30 participants from November 2017 to March 2018 at a single site, with the intervention being delivered until December 2018. It will gather quantitative data using questionnaires and group attendance. Drug treatment group observations and in-depth interviews undertaken with up to 20 service users and 15 service providers to examine experiences and acceptability of the intervention. Study feasibility will be assessed by evaluating the recruitment and retention of participants to the intervention; the feasibility of NHS and third sector organisations working closely to coordinate care for a SSW population; the potential for specialist NHS mental health services to screen and provide EMDR therapy for drug-dependent SSWs and potential costs of implementing the intervention. ETHICS AND DISSEMINATION: This study was approved by South West-Frenchay Research Ethics Committee (REC reference: 17/SW/0033; IRAS ID: 220631) and the Health Research Authority (HRA). Findings will be disseminated through research conferences and peer-reviewed journals.

BACKGROUND: Peer teaching has been used informally throughout the history of medical education. Formal studies within the medical student and allied health care professional communities have found it to be a popular, and highly effective, method of teaching. CONTEXT: Newly qualified doctors are currently an underused resource in terms of teaching one another. INNOVATION: A committee, made up of newly qualified doctors and postgraduate education staff, was established. Using only a few resources, this committee organised regular, peer-led tutorials and used educational needs assessment tools, such as questionnaires, to make improvements to early postgraduate training. IMPLICATION: A realistic and well-received intervention to improve the teaching of newly qualified doctors, which is feasible in the modern, busy health care setting. Other institutions may find this method and its resources valuable. Newly qualified doctors are currently an underused resource in terms of teaching one another.
