Exploring the third delay: an audit evaluating obstetric triage at Mulago National Referral Hospital
BACKGROUND: Mulago National Referral Hospital has the largest maternity unit in sub-Saharan Africa. It is situated in Uganda, where the maternal mortality ratio is 310 per 100,000 live births. In 2010 a ‘Traffic Light System’ was set up to rapidly triage the vast number of patients who present to the hospital every day. The aim of this study was to evaluate the effectiveness of the obstetric department’s triage system at Mulago Hospital with regard to time spent in admissions and to identify urgent cases and factors adversely affecting the system. METHODS: A prospective audit of the obstetric admissions department was carried out at the Mulago Hospital. Data were obtained from tagged patient journeys using two data collection tools and compiled using Microsoft Excel. StatsDirect was used to compose graphs to illustrate the results. RESULTS: Informal triage was occurring 46 % of the time at the first checkpoint in a woman’s journey, but the ‘Traffic Light System’ was not being used and many of the patient’s vital signs were not being recorded. CONCLUSIONS: It is hypothesised that the ‘Traffic Light System’ is not being used due to its focus on examination finding and diagnosis, implying that it is not suitable for an early stage in the patient’s journey. Replacing it with a simple algorithm to categorise women into the urgency with which they need to be seen could rectify this
Job retention vocational rehabilitation for employed people with inflammatory arthritis: adaptations to the WORKWELL trial due to the impact of the COVID-19 pandemic
There are high levels of work disability, absenteeism (sick leave) and presenteeism (reduced productivity) amongst people with inflammatory arthritis. WORKWELL is a multi-centre, randomised controlled trial of job retention vocational rehabilitation for employed people with inflammatory arthritis. The trial tested the effectiveness and cost-effectiveness of the WORKWELL programme compared to the receipt of written self-help information only. Both arms continued to receive usual care. In March 2020, due to the COVID-19 pandemic, the WORKWELL trial paused to recruitment and intervention delivery. To successfully re-start, protocol amendments were rapidly submitted and changes to existing trial procedures were made. The WORKWELL protocol was adapted in response to both the practical issues likely faced by many clinical research studies active across NHS sites during the pandemic and additional trial-specific challenges. A key eligibility criterion for the trial required participants to be in paid work for at least 15 h per week. However, UK national lockdowns led to a substantial proportion of the workforce suddenly being furloughed or unable to work, and many people with arthritis taking immunosuppressive medications were asked to shield themselves. Thus, the number of eligible participants was reduced. Those continuing to work were harder to identify, as hospital clinics moved to remote delivery, and also to then screen, consent and treat, as the hospital research staff and clinical therapists were re-deployed. New recruitment and consent strategies were applied, and where sites had reduced capacity, responsibilities were absorbed by the trial management team. Remote intervention delivery and electronic data capture were also implemented. By rapidly adapting the WORKWELL protocol and procedures, the trial successfully reopened to recruitment in July 2020, only 4 months after the trial pause. We were able to achieve recruitment figures above the pre-COVID target and maintain a high retention rate. In addition, we found many of the protocol changes beneficial, as these streamlined trial procedures, thus improving efficiency. It is likely that many strategies implemented in response to the pandemic may become standard practice in future research within trials of a similar design and methodology.

STIMULATE-ICP-Delphi (symptoms, trajectory, inequalities and management: understanding long-COVID to address and transform existing integrated care pathways Delphi): study protocol
Introduction As mortality rates from COVID-19 disease fall, the high prevalence of long-term sequelae (Long COVID) is becoming increasingly widespread, challenging healthcare systems globally. Traditional pathways of care for Long Term Conditions (LTCs) have tended to be managed by disease-specific specialties, an approach that has been ineffective in delivering care for patients with multi-morbidity. The multi-system nature of Long COVID and its impact on physical and psychological health demands a more effective model of holistic, integrated care. The evolution of integrated care systems (ICSs) in the UK presents an important opportunity to explore areas of mutual benefit to LTC, multi-morbidity and Long COVID care. There may be benefits in comparing and contrasting ICPs for Long COVID with ICPs for other LTCs. Methods and analysis This study aims to evaluate health services requirements for ICPs for Long COVID and their applicability to other LTCs including multi-morbidity and the overlap with medically not yet explained symptoms (MNYES). The study will follow a Delphi design and involve an expert panel of stakeholders including people with lived experience, as well as clinicians with expertise in Long COVID and other LTCs. Study processes will include expert panel and moderator panel meetings, surveys, and interviews. The Delphi process is part of the overall STIMULATE-ICP programme, aimed at improving integrated care for people with Long COVID. Ethics and dissemination Ethical approval for this Delphi study has been obtained (Research Governance Board of the University of York) as have approvals for the other STIMULATE-ICP studies. Study outcomes are likely to inform policy for ICPs across LTCs. Results will be disseminated through scientific publication, conference presentation and communications with patients and stakeholders involved in care of other LTCs and Long COVID
The Non-Abelian Exponentiation theorem for multiple Wilson lines
We study the structure of soft gluon corrections to multi-leg scattering
amplitudes in a non-Abelian gauge theory by analysing the corresponding product
of semi-infinite Wilson lines. We prove that diagrams exponentiate such that
the colour factors in the exponent are fully connected. This completes the
generalisation of the non-Abelian exponentiation theorem, previously proven in
the case of a Wilson loop, to the case of multiple Wilson lines in arbitrary
representations of the colour group. Our proof is based on the replica trick in
conjunction with a new formalism where multiple emissions from a Wilson line
are described by effective vertices, each having a connected colour factor. The
exponent consists of connected graphs made out of these vertices. We show that
this readily provides a general colour basis for webs. We further discuss the
kinematic combinations that accompany each connected colour factor, and
explicitly catalogue all three-loop examples, as necessary for a direct
computation of the soft anomalous dimension at this order.Comment: v2 - typos corrected, references added, to appear in JHEP; 57 pages,

Molecular and pathological insights into Chlamydia pecorum-associated sporadic bovine encephalomyelitis (SBE) in Western Australia
Background Despite its global recognition as a ruminant pathogen, cases of Chlamydia pecorum infection in Australian livestock are poorly documented. In this report, a C. pecorum specific Multi Locus Sequence Analysis scheme was used to characterise the C. pecorum strains implicated in two cases of sporadic bovine encephalomyelitis confirmed by necropsy, histopathology and immunohistochemistry. This report provides the first molecular evidence for the presence of mixed infections of C. pecorum strains in Australian cattle. Case presentation Affected animals were two markedly depressed, dehydrated and blind calves, 12 and 16 weeks old. The calves were euthanized and necropsied. In one calf, a severe fibrinous polyserositis was noted with excess joint fluid in all joints whereas in the other, no significant lesions were seen. No gross abnormalities were noted in the brain of either calf. Histopathological lesions seen in both calves included: multifocal, severe, subacute meningoencephalitis with vasculitis, fibrinocellular thrombosis and malacia; diffuse, mild, acute interstitial pneumonia; and diffuse, subacute epicarditis, severe in the calf with gross serositis. Immunohistochemical labelling of chlamydial antigen in brain, spleen and lung from the two affected calves and brain from two archived cases, localised the antigen to the cytoplasm of endothelium, mesothelium and macrophages. C. pecorum specific qPCR, showed dissemination of the pathogen to multiple organs. Phylogenetic comparisons with other C. pecorum bovine strains from Australia, Europe and the USA revealed the presence of two genetically distinct sequence types (ST). The predominant ST detected in the brain, heart, lung and liver of both calves was identical to the C. pecorum ST previously described in cases of SBE. A second ST detected in an ileal tissue sample from one of the calves, clustered with previously typed faecal bovine isolates. Conclusion This report provides the first data to suggest that identical C. pecorum STs may be associated with SBE in geographically separated countries and that these may be distinct from those found in the gastrointestinal tract. This report provides a platform for further investigations into SBE and for understanding the genetic relationships that exist between C. pecorum strains detected in association with other infectious diseases in livestock
Poor uptake of an online intervention in a cluster randomised controlled trial of online diabetes education for rural general practitioners
Background: In Australia, rural and remote communities have high rates of diabetes-related death and hospitalisation. General practitioners (GPs) play a major role in diabetes detection and management. Education of GPs could optimise diabetes management and improve patient outcomes at a population level. The study aimed to describe the uptake of a continuing medical education intervention for rural GPs and its impact on the viability of a cluster randomised controlled trial of the effects of continuing medical education on whole-town diabetes monitoring and control. Method: Trial design: the cluster randomised controlled trial involved towns as the unit of allocation and analysis with outcomes assessed by de-identified pathology data (not reported here). The intervention programme consisted of an online active learning module, direct electronic access to specialist advice and performance feedback. Multiple rounds of invitation were used to engage GPs with the online intervention content. Evidence-based strategies (e.g. pre-notification, rewards, incentives) were incorporated into the invitations to enrol in the programme. Recruitment to the programme was electronically monitored through the hosting software package during the study intervention period. Results: Eleven matched pairs of towns were included in the study. There were 146 GPs in the 11 intervention towns, of whom 34 (23.3%) enrolled in the programme, and 8 (5.5%) completed the online learning module. No town had more than 10% of the resident GPs complete the learning module. There were no contacts made by GPs regarding requests for specialist advice. Consequently, the trial was discontinued. Conclusion: There is an ongoing need to engage primary care physicians in improving diabetes monitoring and management in rural areas. Online training options, while notionally attractive and accessible, are not likely to have high levels of uptake, even when evidence-based recruitment strategies are implemented
Testing for type 2 diabetes in Indigenous Australians: guideline recommendations and current practice
Objectives: To determine the proportion of Aboriginal Controlled Community Health Service (ACCHS) patients tested according to three national diabetes testing guidelines; to investigate whether specific patient characteristics were associated with being tested.
Design, setting and participants: Cross-sectional study of 20 978 adult Indigenous Australians not diagnosed with diabetes attending 18 ACCHSs across Australia. De-identified electronic whole service data for July 2010 - June 2013 were analysed.
Main outcomes measures: Proportions of patients appropriately screened for diabetes according to three national guidelines for Indigenous Australians: National Health and Medical Research Council (at least once every 3 years for those aged 35 years or more); Royal Australian College of General Practitioners and Diabetes Australia (at least once every 3 years for those aged 18 years or more); National Aboriginal Community Controlled Health Organisation (annual testing of those aged 18 years or more at high risk of diabetes).
Results: 74% (95% CI, 74-75%) of Indigenous adults and 77% (95% CI, 76-78%) of 10 760 patients aged 35 or more had been tested for diabetes at least once in the past 3 years. The proportions of patients tested varied between services (range: all adults, 16-90%; people aged 35 years or more, 23-92%). 18% (95% CI, 18-19%) of patients aged 18 or more were tested for diabetes annually (range, 0.1-43%). Patients were less likely to be tested if they were under 50 years of age, were transient rather than current patients of the ACCHS, or attended the service less frequently.
Conclusions: Some services achieved high rates of 3-yearly testing of Indigenous Australians for diabetes, but recommended rates of annual testing were rarely attained. ACCHSs may need assistance to achieve desirable levels of testing.We gratefully acknowledge funding for this project from the National Health and Medical Research
