Assessing acutely ill children in general practice using the National PEWS and LqSOFA clinical scores: a retrospective cohort study.

BACKGROUND: Clinical tools are needed in general practice to help identify seriously ill children. The Liverpool quick Sequential Organ Failure Assessment (LqSOFA) was validated in an Emergency Department and performed well. The National Paediatric Early Warning score (PEWS) has been introduced in hospitals throughout England with hopes for implementation in general practice. AIM: To validate the LqSOFA and National PEWS in general practice. DESIGN/SETTING: Secondary analysis of 6,703 children <5 years presenting to 225 general practices in England and Wales with acute illnesses, linked to hospital data. METHOD: Variables from the LqSOFA and National PEWS were mapped onto study data to calculate score totals. A primary outcome of admission within two days of GP consultation was used to calculate sensitivity, specificity, negative predictive values (NPV), positive predictive values (PPV) and area-under-the-curve (AUC). RESULTS: 104/6,703 children were hospitalised within two days (pre-test probability 1.6%). The sensitivity of the LqSOFA was 30.6% (95% confidence interval 21.8% - 41.0%), with a specificity of 84.7% (83.7% - 85.6%), PPV of 3.0% (2.1% - 4.4%), NPV of 98.7% (98.4% - 99.0%), and AUC of 0.58 (0.53 - 0.63). The sensitivity of the National PEWS was 81.0% (71.0% - 88.1%), with a specificity of 32.5% (31.2% - 33.8%); PPV of 1.9% (1.5% - 2.5%); NPV of 99.1% (98.4% - 99.4%) and AUC of 0.66 (0.59 - 0.72). CONCLUSION: Although the NPVs appear useful, due to low pre-test probabilities rather than discriminative ability, neither tool accurately identified hospitalisations. Unconsidered use by GPs could result in unsustainable referrals.

Long-term consequences of urinary tract infection in childhood: an electronic population-based cohort study in Welsh primary and secondary care.

BACKGROUND: Childhood urinary tract infection (UTI) can cause renal scarring, and possibly hypertension, chronic kidney disease (CKD), and end-stage renal failure (ESRF). Previous studies have focused on selected populations, with severe illness or underlying risk factors. The risk for most children with UTI is unclear. AIM: To examine the association between childhood UTI and outcomes in an unselected population of children. DESIGN AND SETTING: A retrospective population-based cohort study using linked GP, hospital, and microbiology records in Wales, UK. METHOD: Participants were all children born in 2005-2009, with follow-up until 31 December 2017. The exposure was microbiologically confirmed UTI before the age of 5 years. The key outcome measures were renal scarring, hypertension, CKD, and ESRF. RESULTS: In total, 159 201 children were included; 77 524 (48.7%) were female and 7% (n = 11 099) had UTI before the age of 5 years. A total of 0.16% (n = 245) were diagnosed with renal scarring by the age of 7 years. Odds of renal scarring were higher in children by age 7 years with UTI (1.24%; adjusted odds ratio 4.60 [95% confidence interval [CI] = 3.33 to 6.35]). Mean follow-up was 9.53 years. Adjusted hazard ratios were: 1.44 (95% CI = 0.84 to 2.46) for hypertension; 1.67 (95% CI = 0.85 to 3.31) for CKD; and 1.16 (95% CI = 0.56 to 2.37) for ESRF. CONCLUSION: The prevalence of renal scarring in an unselected population of children with UTI is low. Without underlying risk factors, UTI is not associated with CKD, hypertension, or ESRF by the age of 10 years. Further research with systematic scanning of children's kidneys, including those with less severe UTI and without UTI, is needed to increase the certainty of these results, as most children are not scanned. Longer follow-up is needed to establish if UTI, without additional risk factors, is associated with hypertension, CKD, or ESRF later in life.

Curriculum mapping to audit and grow longitudinal graduate medical education leadership training.

BACKGROUND: Residents need and want practical leadership training, yet leadership curricula are lacking in graduate medical education (GME). We describe our process of curriculum mapping, a method for auditing a curriculum, and its role in iterative leadership curriculum development. AIMS: To show how to create a curriculum map for auditing a curriculum using examples from our leadership curriculum and to demonstrate its value through case examples of leadership education integration into existing resident experiences. METHODS: We selected our recent systematic review on current leadership curricula to prioritise leadership content given it was the basis for our initial curriculum. We identified existing resident experiences where training can occur. We use the selected content and training environments, layered with a modified Miller's pyramid, to construct a curriculum map. RESULTS: Our curriculum map provides an example of curriculum auditing that reveals opportunities for leadership training that could be integrated into current residency experiences. We provide case examples of application. DISCUSSION: Effective leadership training should address critical topics and capitalise on experiential learning opportunities that exist within residency training programmes. The training must be seamlessly integrated into the demanding obligations of GME trainees, a process that can be achieved using curriculum mapping. Curriculum mapping can provide insight into a residency programme's leadership curriculum and create a direction for future leadership curriculum development.

Case 324: CHANTER Syndrome.

HISTORY: A 69-year-old right-handed man with a history of substance use disorder, hypertension, and diabetes presented to the emergency department in an unresponsive state. Upon examination, apart from tachycardia (heart rate, 108 beats per minute), vital signs were within normal ranges (blood pressure, 134/102 mm Hg; temperature, 97.9 ºF (36.6 ºC); respiratory rate, 16 per minute; oxygen saturation, 96%). The patient had a Glasgow coma scale score of 8. Otherwise, the physical examination revealed no abnormalities. Prior psychiatric and surgical histories were unremarkable. There was no history of recent travel, camping, hiking, or vaccination. No family history could be obtained. Laboratory work-up revealed an elevated creatine kinase level (49 006 U/L [818.4 µkat/L]; normal reference range, 10-205 U/L [0.17-3.42 µkat/L]). An electrocardiogram showed sinus tachycardia without evidence of cardiac ischemia. An echocardiogram was unremarkable. Alanine aminotransferase (126 U/L [2.10 µkat/L]; normal reference range, 0-40 U/L [0-0.67 µkat/L]) and aspartate aminotransferase (488 U/L [8.15 µkat/L]; normal reference range, 3-44 U/L [0.05-0.74 µkat/L]) levels were elevated. Polymerase chain reaction results were negative for HIV-1, HIV-2, syphilis treponemal, and COVID-19 antibodies. The remaining routine laboratory work-up findings were within normal limits. Urine drug screening was positive for cocaine, marijuana, fentanyl, and benzodiazepines. Naloxone was administered, but the patient remained unresponsive. Intubation was performed for airway protection. Noncontrast and contrast-enhanced CT of the head and CT angiography were performed in the emergency department to rule out an acute intracranial abnormality. Multisequence MRI of the brain with administration of intravenous contrast material was ordered for further assessment. CT of the abdomen and pelvis was unremarkable (images not shown).

The Association of Resilience with Psychosocial Outcomes in Teenagers and Young Adults with Cancer.

Purpose: There is limited research on the psychological impact of cancer for teenagers and young adults (TYAs) and the role of protective factors such as resilience. This study investigated associations between resilience and psychosocial outcomes in this group. Methods: Data were collected from TYAs (aged 16-24) who attended the TYA cancer clinic at Guy's Hospital between 2013 and 2021. Participants (N = 63) completed psychosocial questionnaires within 4 weeks of their treatment start date (T1) and again between 9 and 15 months later (T2). We used separate multivariable linear regression models to analyze associations of resilience (Brief Resilience Questionnaire) with outcomes measured at T2, including symptoms of depression (Patient Health Questionnaire [PHQ]-9), anxiety (Generalized Anxiety Disorder [GAD]-7), and subjective quality of life. Models were adjusted for age, gender, ethnicity, and T1 outcome assessments. Results: Higher resilience at T1 was associated with increased anxiety (ß = 1.68; bootstrapped confidence interval [95% CI -0.28 to 3.19]), depression (ß = 1.24; [-0.85 to 2.90]), and quality of life (5.76; [-0.88 to 15.60]). In contrast, an increase in resilience over time was associated with decreases in the same period in anxiety (ß = -3.16; [-5.22 to -1.47]) and depression (ß = -2.36, [-4.41 to -0.58]), and an increase in quality of life (ß = 9.82, [-0.24 to 21.13]). Conclusion: Increases in resilience during cancer treatment were associated with reduced symptoms of depression and anxiety in TYAs. We discuss factors likely to influence these outcomes, the implications for psychosocial interventions in this population, and identify further research to explore the impact of other factors such as diagnosis and treatment type.

A Systematic Review of the Psychosocial Measures Used in Teenage and Young Adult Cancer.

Background: Teenagers and young adults (TYAs; ages 16-24 in the United Kingdom) with cancer have specific needs and experience worse physiological and psychological outcomes compared with pediatric and adult cancer. In the United Kingdom, psychosocial screening is a mandatory part of TYA care. However, there is a lack of age-appropriate and acceptable psychosocial measures for this population. This review aimed to (1) identify the psychosocial measures utilized and available for TYA cancer and (2) describe their psychometric properties. Methods: We searched five databases for studies meeting the eligibility criteria. We extracted data relevant to the review and assessed study quality using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) guidelines and the Hughes Quality Assessment Tool developed by the research team. Results: We identified 40 studies that included 105 psychosocial measures. The main constructs measured were distress, depression, and anxiety. The TYA age range varied widely. Reporting of psychosocial measures and their psychometric properties was poor, and most measures were not validated or developed for TYA cancer populations. Discussion: There is an urgent need for psychosocial measures that are designed for and validated in TYA cancer populations. Appropriate measures would enable clinicians to reliably identify and effectively support the psychosocial challenges faced by TYAs. The use of validated psychosocial measures enables earlier detection of difficulties, fosters patient-centered care, and is cost-effective since resources can be allocated to those most in need.

Acute Renal Failure with Severe Loin Pain and Patchy Renal Ischemia after Anaerobic Exercise in Active Duty Marines.

Acute renal failure with severe loin pain and patchy renal ischemia after anaerobic exercise (ALPE) is a rare cause of exertional acute kidney injury. The proposed mechanism of injury in ALPE is renovascular spasm, in the setting of oxidative stress and muscular damage, which creates a characteristic wedge-shaped infarction pattern on delayed imaging. Patients present with nausea, vomiting, loin or abdominal pain, and fatigue within 1-2 days of anaerobic exercise, associated with an acute rise in serum creatinine, which generally plateaus within 3 days. This process is likely exacerbated by dehydration, analgesic usage, and lower baseline fitness levels. This disease process is distinct from rhabdomyolysis, in that creatine kinase levels are not significantly elevated, myoglobinuria is not seen, and aggressive fluid resuscitation is not beneficial. We present three cases of ALPE following participation in the Marine Combat Fitness Test (CFT), an anaerobic evolution. Medical workup demonstrated no additional etiology for acute renal failure. The average peak creatinine in these patients was 2.9 mg/dL, and all demonstrated return to normal renal function, without hemodialysis. One patient experienced recurrent ALPE, after short-interval CFT participation. Military medical providers should be aware of this diagnosis when evaluating service members with acute renal injury after exercise. The clinical course is benign, and affected service members are at increased risk of recurrence, with subsequent intense exercise. Service members should engage in a graduated exercise program, before intense exercise activities, and should be monitored closely for recurrent renal injury.

Case 324.

HISTORY: A 69-year-old right-handed man with a history of substance use disorder, hypertension, and diabetes presented to the emergency department in an unresponsive state. Upon examination, apart from tachycardia (heart rate, 108 beats per minute), vital signs were within normal ranges (blood pressure, 134/102 mm Hg; temperature, 97.9°F [36.6°C]; respiratory rate, 16 breaths per minute; oxygen saturation, 96%). He had a Glasgow coma scale score of 8. Otherwise, the physical examination revealed no abnormalities. His prior psychiatric and surgical histories were unremarkable. There was no history of recent travel, camping, hiking, or vaccination. No family history could be obtained. Laboratory work-up revealed an elevated creatine kinase level (49 006 U/L [818.4 µkat/L]; normal reference range, 10-205 U/L [0.17-3.42 µkat/L]). An electrocardiogram showed sinus tachycardia without evidence of cardiac ischemia. An echocardiogram was unremarkable. Alanine aminotransferase (126 U/L [2.10 µkat/L]; normal reference range, 0-40 U/L [0-0.67 µkat/L]) and aspartate aminotransferase (488 U/L [8.15 µkat/L]; normal reference range, 3-44 U/L [0.05-0.74 µkat/L]) levels were elevated. Polymerase chain reaction results were negative for HIV-1, HIV-2, syphilis treponemal, and COVID-19 antibodies. The rest of the routine laboratory work-up findings were within normal limits. Urine drug screening was positive for cocaine, marijuana, fentanyl, and benzodiazepines. Naloxone was administered, but the patient remained unresponsive. Intubation was performed for airway protection. Noncontrast and contrast-enhanced CT of the head (Fig 1) and CT angiography were performed in the emergency department to rule out an acute intracranial abnormality. Multisequence MRI of the brain with administration of intravenous contrast material was ordered for further assessment (Figs 2-4). CT of the abdomen and pelvis was unremarkable (images not shown).

Associations between AI-Assisted Tumor Amphiregulin and Epiregulin IHC and Outcomes from Anti-EGFR Therapy in the Routine Management of Metastatic Colorectal Cancer.

PURPOSE: High tumor production of the EGFR ligands, amphiregulin (AREG) and epiregulin (EREG), predicted benefit from anti-EGFR therapy for metastatic colorectal cancer (mCRC) in a retrospective analysis of clinical trial data. Here, AREG/EREG IHC was analyzed in a cohort of patients who received anti-EGFR therapy as part of routine care, including key clinical contexts not investigated in the previous analysis. EXPERIMENTAL DESIGN: Patients who received panitumumab or cetuximab ± chemotherapy for treatment of RAS wild-type mCRC at eight UK cancer centers were eligible. Archival formalin-fixed paraffin-embedded tumor tissue was analyzed for AREG and EREG IHC in six regional laboratories using previously developed artificial intelligence technologies. Primary endpoints were progression-free survival (PFS) and overall survival (OS). RESULTS: A total of 494 of 541 patients (91.3%) had adequate tissue for analysis. A total of 45 were excluded after central extended RAS testing, leaving 449 patients in the primary analysis population. After adjustment for additional prognostic factors, high AREG/EREG expression (n = 360; 80.2%) was associated with significantly prolonged PFS [median: 8.5 vs. 4.4 months; HR, 0.73; 95% confidence interval (CI), 0.56-0.95; P = 0.02] and OS [median: 16.4 vs. 8.9 months; HR, 0.66 95% CI, 0.50-0.86; P = 0.002]. The significant OS benefit was maintained among patients with right primary tumor location (PTL), those receiving cetuximab or panitumumab, those with an oxaliplatin- or irinotecan-based chemotherapy backbone, and those with tumor tissue obtained by biopsy or surgical resection. CONCLUSIONS: High tumor AREG/EREG expression was associated with superior survival outcomes from anti-EGFR therapy in mCRC, including in right PTL disease. AREG/EREG IHC assessment could aid therapeutic decisions in routine practice. See related commentary by Randon and Pietrantonio, p. 4021.

Perspectives of Statistician, Microbiologist, and Clinician Stakeholders on the Use of Microbiological Outcomes in Randomised Trials of Antimicrobial Stewardship Interventions.

Microbiological data are used as indicators of infection, for diagnosis, and the identification of antimicrobial resistance in trials of antimicrobial stewardship interventions. However, several problems have been identified in a recently conducted systematic review (e.g., inconsistency in reporting and oversimplified outcomes), which motivates the need to understand and improve the use of these data including analysis and reporting. We engaged key stakeholders including statisticians, clinicians from both primary and secondary care, and microbiologists. Discussions included issues identified in the systematic review and questions about the value of using microbiological data in clinical trials, perspectives on current microbiological outcomes reported in trials, and alternative statistical approaches to analyse these data. Various factors (such as unclear sample collection process, dichotomising or categorising complex microbiological data, and unclear methods of handling missing data) were identified that contributed to the low quality of the microbiological outcomes and the analysis of these outcomes in trials. Whilst not all of these factors would be easy to overcome, there is room for improvement and a need to encourage researchers to understand the impact of misusing these data. This paper discusses the experience and challenges of using microbiological outcomes in clinical trials.

Human parechovirus meningoencephalitis.

Human parechovirus-3 (HPeV-3) infection is one of the differential diagnoses of neonatal meningoencephalitis. A 13-day-old full-term female neonate presented with a seizure. Brain MRI showed classic imaging findings of the meningoencephalitis which was confirmed on cerebrospinal fluid analysis. Contribution: The HPeV-3 is an emerging pathogen for neonatal meningoencephalitis. The case in this study is unique with classic imaging findings, which are not routinely encountered in day-to-day practice. This case raises reader awareness.

What is the Diagnostic Accuracy of Novel Urine Biomarkers for Urinary Tract Infection?

Background: Urinary tract infection (UTI) affects half of women at least once in their lifetime. Current diagnosis involves urinary dipstick and urine culture, yet both methods have modest diagnostic accuracy, and cannot support decision-making in patient populations with high prevalence of asymptomatic bacteriuria, such as older adults. Detecting biomarkers of host response in the urine of hosts has the potential to improve diagnosis. Objectives: To synthesise the evidence of the diagnostic accuracy of novel biomarkers for UTI, and of their ability to differentiate UTI from asymptomatic bacteriuria. Design: A systematic review. Data Sources and Methods: We searched MEDLINE, EMBASE, CINAHL and Web of Science for studies of novel biomarkers for the diagnosis of UTI. We excluded studies assessing biomarkers included in urine dipsticks as these have been well described previously. We included studies of adult patients (≥16 years) with a suspected or confirmed urinary tract infection using microscopy and culture as the reference standard. We excluded studies using clinical signs and symptoms, or urine dipstick only as a reference standard. Quality appraisal was performed using QUADAS-2. We summarised our data using point estimates and data accuracy statistics. Results: We included 37 studies on 4009 adults measuring 66 biomarkers. Study quality was limited by case-control design and study size; only 4 included studies had a prospective cohort design. IL-6 and IL-8 were the most studied biomarkers. We found plausible evidence to suggest that IL-8, IL-6, GRO-a, sTNF-1, sTNF-2 and MCR may benefit from more rigorous evaluation of their potential diagnostic value for UTI. Conclusions: There is insufficient evidence to recommend the use of any novel biomarker for UTI diagnosis at present. Further evaluation of the more promising candidates, is needed before they can be recommended for clinical use.

Antibiotic consumption and time to recovery from uncomplicated urinary tract infection: secondary analysis of observational data from a point-of-care test trial.

BACKGROUND: Randomised trials provide high-quality evidence on the effects of prescribing antibiotics for urinary tract infection (UTI) but may not reflect the effects in those who consume antibiotics. Moreover, they mostly compare different antibiotic types or regimens but rarely include a 'no antibiotic' group. AIM: To estimate the effect of antibiotic consumption, rather than prescription, on time to recovery in females with uncomplicated UTI. DESIGN AND SETTING: Secondary analysis of 14-day observational data from a point-of-care test trial for UTI in primary care in England, the Netherlands, Spain, and Wales, which ran from 2012 to 2014. Clinicians treated patients using their own judgement, providing immediate, delayed, or no antibiotic. METHOD: UTI-symptomatic females who either consumed or did not consume antibiotics during a 14-day follow-up were included. Antibiotic consumption was standardised across participants and grouped into either ≤3 or >3 standardised antibiotic days. To account for confounders, a robust propensity score matching analysis was conducted. Adjusted Kaplan-Meier and Cox proportional hazard models were employed to estimate time to recovery and hazard ratios, respectively. RESULTS: A total of n = 333 females who consumed antibiotics and n = 80 females who did not consume antibiotics were identified and included in the study. The adjusted median time to recovery was 2 days longer among patients who did not consume antibiotics (9 days, 95% confidence interval [CI] = 7 to 12) compared with those who did (7 days, 95% CI = 7 to 8). No difference was found between those who consumed ≤3 (7 days, 95% CI = 7 to 8) compared with >3 standardised antibiotic days (7 days, 95% CI = 6 to 9). CONCLUSION: Consuming antibiotics was associated with a reduction in self-reported time to recovery, but more antibiotics exposure was not associated with faster recovery in this study.

The relationship between HIV pre-exposure prophylaxis, sexually transmitted infections, and antimicrobial resistance: a qualitative interview study of men who have sex with men.

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) is a medication that prevents the acquisition of HIV. It has been targeted towards men who have sex with men (MSM). Since its introduction there have been concerns raised around changes in sexual behaviour such as increased condomless anal intercourse (CAI), leading to an elevation in sexually transmitted infections (STIs). With antimicrobial resistant strains of STIs rising, there are concerns that PrEP may be contributing to this growth. This study aims to understand how MSM conceptualise the relationship between PrEP, STIs and antimicrobial resistance (AMR). METHODS: Twenty semi-structured interviews were conducted online using Zoom. Participants include a mix of PrEP related experiences (never used, currently use, previously used). Reflexive thematic analysis was undertaken by the lead author with 10% of transcripts double coded. RESULTS: MSM in Wales have positive views and a good knowledge of PrEP and awareness of bacterial STIs. PrEP is perceived by many to lead to a reduction in condom use and increase in STIs but reported condom use behaviours presented to be stable in terms of PrEP initiation. PrEP use is influenced by increased concern for HIV and minimal concern for bacterial STIs. Awareness of AMR STIs was lacking. CONCLUSIONS: There is a belief that PrEP use will lead to an increase in STI rates through reduced condom use, despite reported behaviours often being stable in relation to PrEP initiation, PrEP stigma may be influencing this dichotomy. Concern and awareness for resistant STIs is low, with little association to PrEP.

Myocardial infarction and stroke subsequent to urinary tract infection (MISSOURI): protocol for a self-controlled case series using linked electronic health records.

INTRODUCTION: There is increasing interest in the relationship between acute infections and acute cardiovascular events. Most previous research has focused on understanding whether the risk of acute cardiovascular events increases following a respiratory tract infection. The relationship between urinary tract infections (UTIs) and acute cardiovascular events is less well studied. Therefore, the aim of this study is to determine whether there is a causal relationship between UTI and acute myocardial infarction (MI) or stroke. METHODS AND ANALYSIS: We will undertake a self-controlled case series study using linked anonymised general practice, hospital admission and microbiology data held within the Secure Anonymised Information Linkage (SAIL) Databank. Self-controlled case series is a relatively novel study design where individuals act as their own controls, thereby inherently controlling for time-invariant confounders. Only individuals who experience an exposure and outcome of interest are included.We will identify individuals in the SAIL Databank who have a hospital admission record for acute MI or stroke during the study period of 2010-2020. Individuals will need to be aged 30-100 during the study period and be Welsh residents for inclusion. UTI will be identified using general practice, microbiology and hospital admissions data. We will calculate the incidence of MI and stroke in predefined risk periods following an UTI and in 'baseline' periods (without UTI exposure) and use conditional Poisson regression models to derive incidence rate ratios. ETHICS AND DISSEMINATION: Data access, research permissions and approvals have been obtained from the SAIL independent Information Governance Review Panel, project number 0972. Findings will be disseminated through conferences, blogs, social media threads and peer-reviewed journals. Results will be of interest internationally to primary and secondary care clinicians who manage UTIs and may inform future clinical trials of preventative therapy.

Perceived threat of COVID-19, attitudes towards vaccination, and vaccine hesitancy: A prospective longitudinal study in the UK.

OBJECTIVES: Using the Health Belief Model as a conceptual framework, we investigated the association between attitudes towards COVID-19, COVID-19 vaccinations, and vaccine hesitancy and change in these variables over a 9-month period in a UK cohort. METHODS: The COPE study cohort (n = 11,113) was recruited via an online survey at enrolment in March/April 2020. The study was advertised via the HealthWise Wales research registry and social media. Follow-up data were available for 6942 people at 3 months (June/July 2020) and 5037 at 12 months (March/April 2021) post-enrolment. Measures included demographics, perceived threat of COVID-19, perceived control, intention to accept or decline a COVID-19 vaccination, and attitudes towards vaccination. Logistic regression models were fitted cross-sectionally at 3 and 12 months to assess the association between motivational factors and vaccine hesitancy. Longitudinal changes in motivational variables for vaccine-hesitant and non-hesitant groups were examined using mixed-effect analysis of variance models. RESULTS: Fear of COVID-19, perceived susceptibility to COVID-19, and perceived personal control over COVID-19 infection transmission decreased between the 3- and 12-month surveys. Vaccine hesitancy at 12 months was independently associated with low fear of the disease and more negative attitudes towards COVID-19 vaccination. Specific barriers to COVID-19 vaccine uptake included concerns about safety and efficacy in light of its rapid development, mistrust of government and pharmaceutical companies, dislike of coercive policies, and perceived lack of relaxation in COVID-19-related restrictions as the vaccination programme progressed. CONCLUSIONS: Decreasing fear of COVID-19, perceived susceptibility to the disease, and perceptions of personal control over reducing infection-transmission may impact future COVID-19 vaccination uptake.

Accuracy of the NICE traffic light system in children presenting to general practice: a retrospective cohort study.

BACKGROUND: The National Institute for Health and Care Excellence (NICE) traffic light system was created to facilitate the assessment of unwell children in primary care. To the authors' knowledge, no studies have validated this tool in UK general practice. AIM: To evaluate the accuracy of this system for detecting serious illness in children presenting to general practice. DESIGN AND SETTING: A retrospective diagnostic accuracy study was undertaken, using a cohort of acutely unwell children aged <5 years presenting to general practice in England and Wales. METHOD: The traffic light categories of 6703 children were linked with hospital data to identify admissions and diagnoses. The sensitivity and specificity of these categories were calculated against the reference standard: a hospital-diagnosed serious illness within 7 days of GP consultation, measured using International Classification of Diseases, 10th Revision codes. RESULTS: In total, 2116 (31.6%) children were categorised as 'red'; 4204 (62.7%) as 'amber'; and 383 (5.7%) as 'green'. There were 139 (2.1%) children who were admitted to hospital within 7 days of consultation, of whom 17 (12.2%; 0.3% overall) had a serious illness. The sensitivity of the red category (versus amber and green) was 58.8% (95% confidence interval [CI] = 32.9 to 81.6) and the specificity 68.5% (95% CI = 67.4 to 69.6). The sensitivity and specificity of red and amber combined (versus green) was 100% (95% CI = 80.5 to 100) and 5.7% (95% CI = 5.2 to 6.3), respectively. CONCLUSION: The NICE traffic light system did not accurately detect children admitted with a serious illness, nor those not seriously ill who could have been managed at home. This system is not suitable for use as a clinical tool in general practice. Further research is required to update or replace the system.

A systematic review investigating the use of microbiology outcome measures in randomized controlled trials evaluating antimicrobial stewardship interventions published between 2011 and 2021.

INTRODUCTION: Antimicrobial stewardship interventions (ASIs) aim to reduce the emergence of antimicrobial resistance. We sought to systematically evaluate how microbiological outcomes have been handled and analysed in randomized controlled trials (RCTs) evaluating ASIs. METHODS: We searched PubMed and Embase from 2011-21. Studies were selected if they were RCTs evaluating ASIs. A narrative synthesis approach was taken, identifying whether the study reported any microbiological data (bacterial genus/species; bacterial colony counts; prevalence of bacterial, microbiologically defined infections; and antibiotic susceptibility, measured pre-randomization or post-randomization in one arm only) or outcomes (post-randomization data compared between arms). Studies with or without microbiological data/outcomes were summarized in terms of study characteristics, methods of reporting and analysis of these outcomes. RESULTS: We identified 117 studies, with 34 (29.1%) collecting microbiological data and 18 (15.4%) reporting microbiological outcomes. Most studies with microbiological outcomes were conducted in secondary care (12/18, 66.7%) and targeted adult populations (14/18, 77.8%), and the intervention involved biomarker-guided rapid diagnostic testing (7/18, 38.9%). The overall quality of reporting and analysing microbiological outcomes was low and inconsistent. The selected study population in analyses and methods of handling missing data were unclear. CONCLUSIONS: This review demonstrates that the quality of handling and reporting microbiological outcomes in RCTs of ASIs was low. The lack of consistency and clarity made it difficult to compare the findings across studies, limiting policy- and clinical decision-making. Therefore, there is a clear need for the development of guidance for handling microbiological outcomes in RCTs and adopting appropriate methods to evaluate these data carefully.

Changing sexual behaviours amongst MSM during the COVID-19 restrictions in Wales: a mixed methods study.

BACKGROUND: The COVID-19 pandemic and its associated restrictions stopped people freely engaging in sexual behaviour. We explored sexual behaviour amongst men who have sex with men (MSM) using mixed methods during the multiple lockdowns in Wales. METHODS: An online survey was advertised on social media platforms (focusing on Welsh LGBT groups), from June 2020 to July 2020. MSM over 16 years were invited to take part if they were resident in Wales. Qualitative interviews were undertaken as part of a study examining knowledge and awareness of sexual health. Interviews were conducted between September 2020 and February 2021 via Zoom©. Interview data was analysed thematically and integrated with survey data. RESULTS: The survey received 70 responses, 60% (n = 42) reported not having sexual activity during lockdown. Restrictions altered the number of new sexual partners per week with over 80% (n = 56) not having any new sexual partners for the 12 weeks of the first lockdown. However, as the weeks progressed following the first lockdown there was an increase in the number of new sexual partners. Interview data indicated that the COVID-19 pandemic had a large impact on reducing sexual behaviour with other MSM in Wales. 'Lockdown fatigue' was viewed to result in different levels of adherence to the lockdown rules depending on the lockdown being discussed. Of those engaging in sex outside the rules, 'shame' was commonly reported. The restrictions were believed to have a positive impact on reducing the spread of sexually transmitted infections. CONCLUSIONS: The COVID-19 pandemic and associated restrictions had a significant impact on sexual behaviours among MSM in Wales, with the majority fully adhering to the lockdown rules. Although the population were largely compliant with the lockdown restrictions, lockdown fatigue may suggest that any future lockdowns might not have the same effect.

Is the NICE traffic light system fit-for-purpose for children presenting with undifferentiated acute illness in primary care?

BACKGROUND: The National Institute of Clinical Excellence (NICE) traffic light system uses children's symptoms and signs to categorise acute infections into red, amber and green. To our knowledge, no study has described the proportion of children with acute undifferentiated illness who fall into these categories in primary care, which is important since red and amber children are considered at higher risk of serious illness requiring urgent secondary care assessment. AIM: To estimate the proportion of acutely unwell children presenting to primary care classified by the NICE traffic light system as red, amber or green, and to describe their initial management. DESIGN AND SETTING: Secondary analysis of the Diagnosis of Urinary Tract infection in Young children prospective cohort study. METHOD: 6797 children under 5 years presenting to 225 general practices with acute undifferentiated illness were retrospectively mapped to the NICE traffic light system by a panel of general practitioners. RESULTS: 6406 (94%) children were classified as NICE red (32%) or amber (62%) with 1.6% red and 0.3%, respectively, referred the same day for hospital assessment; and 46% and 31%, respectively, treated with antibiotics. The remaining 385 (6%) were classified green, with none referred and 27% treated with antibiotics. Results were robust to sensitivity analyses. CONCLUSION: The majority of children presenting to UK primary care with acute undifferentiated illness meet red or amber NICE traffic light criteria,with only 6% classified as low risk, making it unfit for use in general practice. Research is urgently needed to establish as triage system suitable for general practice.
