Unilateral axillary adenopathy following COVID-19 vaccination: a multimodality pictorial illustration and review of current guidelines

We present a multimodality pictorial review of axillary lymphadenopathy in patients recently vaccinated against COVID-19. As the mass vaccination programme continues to be rolled out worldwide in an effort to combat the pandemic, it is important that radiologists consider recent COVID-19 vaccination in the differential diagnosis of unilateral axillary lymphadenopathy and are aware of typical appearances across all imaging methods. We review current guidelines on the management of unilateral axillary lymphadenopathy in the context of recent COVID-19 vaccination.

222 Rn emanation measurements for the XENON1T experiment

The selection of low-radioactive construction materials is of utmost importance for the success of low-energy rare event search experiments. Besides radioactive contaminants in the bulk, the emanation of radioactive radon atoms from material surfaces attains increasing relevance in the effort to further reduce the background of such experiments. In this work, we present the 222 Rn emanation measurements performed for the XENON1T dark matter experiment. Together with the bulk impurity screening campaign, the results enabled us to select the radio-purest construction materials, targeting a 222 Rn activity concentration of 10 μ Bq / kg in 3.2 t of xenon. The knowledge of the distribution of the 222 Rn sources allowed us to selectively eliminate problematic components in the course of the experiment. The predictions from the emanation measurements were compared to data of the 222 Rn activity concentration in XENON1T. The final 222 Rn activity concentration of ( 4.5 ± 0.1 ) μ Bq / kg in the target of XENON1T is the lowest ever achieved in a xenon dark matter experiment.

Search for Coherent Elastic Scattering of Solar ^{8}B Neutrinos in the XENON1T Dark Matter Experiment

We report on a search for nuclear recoil signals from solar ^{8}B neutrinos elastically scattering off xenon nuclei in XENON1T data, lowering the energy threshold from 2.6 to 1.6  keV. We develop a variety of novel techniques to limit the resulting increase in backgrounds near the threshold. No significant ^{8}B neutrinolike excess is found in an exposure of 0.6  t×y. For the first time, we use the nondetection of solar neutrinos to constrain the light yield from 1-2 keV nuclear recoils in liquid xenon, as well as nonstandard neutrino-quark interactions. Finally, we improve upon world-leading constraints on dark matter-nucleus interactions for dark matter masses between 3 and 11  GeV c^{-2} by as much as an order of magnitude.

Aboriginal community controlled health organisations address health equity through action on the social determinants of health of Aboriginal and Torres Strait Islander peoples in Australia

BACKGROUND

Indigenous populations globally are continually striving for better health and wellbeing due to experiencing significant health and social inequities. The social determinants of health are important contributors to health outcomes. Comprehensive primary health care that is governed and delivered by Indigenous people extends beyond the biomedical model of care to address the social determinants of health. Aboriginal Community Controlled Health Organisations (ACCHOs) are known to provide culturally informed, holistic health services that directly and indirectly address the social determinants of health. The range and extent of their activities in addressing the social determinants of health, however, is not well documented.

METHODS

The most recent ACCHO annual reports were retrieved online or by direct correspondence. For coding consistency, a dictionary informed by the World Health Organization's Conceptual Framework for Action on the Social Determinants of Health was developed. A document and textual analysis of reports coded ACCHO activities and the determinants of health they addressed, including intermediary determinants, socio-economic position and/or socio-political context. Summary statistics were reported. Representative quotes illustrating the unique nature of ACCHO service provision in addressing the social determinants of health were used to contextualise the quantitative findings.

RESULTS

Sixty-seven annual reports were collected between 2017 and 2018. Programs were delivered to population groups across the life span. Fifty three percent of reports identified programs that included work at the socio-political level and all annual reports described working to improve socioeconomic position and intermediary determinants of health through their activities. Culture had a strong presence in program delivery and building social cohesion and social capital emerged as themes.

CONCLUSIONS

This study provides evidence of the considerable efforts of the ACCHO sector, as a primary health care provider, in addressing the social determinants of health and health inequity experienced by Indigenous communities. For the Aboriginal and Torres Strait Islander population, ACCHOs not only have an essential role in addressing immediate healthcare needs but also invest in driving change in the more entrenched structural determinants of health. These are important actions that are likely to have an accumulative positive effect in closing the gap towards health equity.

Diagnostic Accuracy & Pathology Revised Reports: Evidence-Based Guideline Development

Introduction/Objective

Diagnostic errors in pathology may have adverse impact on patient outcomes and are often rectified through revised reports (RR). Improving patient outcomes with accurate RR is a tangible yet challenging benefit to assuring continuous quality improvement (CQI). Assessment and elevation of RR optimization requires counterbalance of workflow complexity in the diagnostic reporting domain. Implications inform best-practice guidelines for pathology RR and exemplify improved patient outcomes by driving down negative impacts from diagnostic errors.

Methods

A “Survey for RR in Pathology: Reality & Best Practices” was sent via email to relevant stakeholders. The 8-item survey was designed by the National Pathology Quality Registry team & ASCP’s Institute for Science, Technology & Policy. The model included quantitative and qualitative feedback to probe current experiences with RR. The survey was open April 1-30, 2019, via Key Survey and used snowball sampling.

Results

Key results illuminate necessity for RR standardization. Survey findings represent 172 respondents. Ninety- two percent of respondents indicated report accuracy as a major indication for optimizing RR practices & positively impacting patient care. Pathology practices assure appropriate RR by notifying a care provider when a change in diagnosis necessitates RR (89%) & 86% of respondents indicate delineation of RR types (e.g. addenda, amendment). Still 54% of respondents see inappropriate RR use with lack of notification to care providers and 48% indicate no delineation of RR types. This balance-counterbalance highlights deviations from optimized RR and a need for guidelines. Effects on patient care or impact to a patient’s treatment plan was indicated by 43% who affirmed stratification of diagnostic discrepancies as major vs. minor. Solely focusing on changes in diagnosis (benign vs. malignant) was heralded by 19% of respondents as a reason to categorize diagnostic discrepancies. Forty-two percent of respondents indicate data-driven CQI in the RR domain.

Conclusion

Identified RR practice gaps decrease diagnostic accuracy, confirming the need for optimal RR guidelines. RR guidelines should focus on standardized nomenclature; active dialogue between laboratory team & clinical care partners; streamlined workflows to assure accuracy; & valuing transparency to derive improved patient outcomes based on high-quality diagnostic pathology RR.

Dermatological games: Part 2. What has changed 40 years on?

In this two-part report, we review and critically appraise 'Dermatological games' by J. A. Cotterill, a seminal article published in 1981, which attempted to explain the interaction between dermatologists and patients using Berne's game theory. Part 1 described and critically appraised the educational value of Cotterill's original list of games in relation to how they apply to dermatology practice. In Part 2, a list of new 'games' that might be observed in current dermatological practice is introduced. The relevance of Cotterill's paper and an explanation for why his article remains relevant to dermatology practice and training today is scrutinized, in order to stimulate discussion and improve patient care.

Dermatological games: Part 1. Original description and critique

'Dermatological games' by J. A. Cotterill was a seminal article published in 1981, which attempted to explain the interaction between dermatologists and patients using Berne's game theory. In Part 1 of this series of two reviews, we review Cotterill's original list of games and how they applied to dermatology in the context of when they were written. We then critically appraise Cotterill's article and arguments. Although the article was deliberately provocative, we found Cotterill's arguments to be well-structured and logical, and the 'games' described are well-conceived. Cotterill's candid analysis of doctors' motivations and the potential impact on the patient is refreshing and insightful. It is striking that, 40 years on, many of the original 'games' described remain recognizable in current practice. In Part 2, a list of new 'games' that might be observed in modern dermatological practice is introduced. The relevance of Cotterill's paper and an explanation for why his educational article remains relevant to dermatology practice and training today is scrutinized in order to stimulate discussion, promote education and improve patient care.

Economic impacts of implementing a national smoke-free prison policy

Background

Worldwide, over 600,000 non-smokers are killed annually due to exposure to secondhand smoke (SHS); the UK societal cost of SHS is estimated at £700million per annum. Prior to recent smoke free policy in Scottish prisons smoking rates were very high (70-75%), well above population rates, subjecting people in custody (PiC) and prison staff to high levels of SHS. Eradicating SHS exposure in prisons could lead to improved health in previous smokers and non-smokers alike, and decrease demand on the National Health Service. However, to date, there is little evidence relating to the economic impact of smoking bans in prisons.

Methods

An economic evaluation estimating the short-term and lifetime impacts of smokefree prison policy in Scotland policy used data from the TIPs study (Jun 2016-Nov 2019) for prison staff and PiC. The analyses adopted a public health and personal perspective and key resources included: implementation costs, cessation support services, health service use and personal costs. For the short-term analyses data were sourced from TIPs staff and PiC surveys, and routine data from the Scottish Prison Service and NHS National Services Scotland. Outcomes included SHS exposure, staff sickness absence, violent incidents and quality adjusted life years (QALYs). The life-time analysis used a Markov model to estimate cost per QALY for both staff and PiC.

Results

SHS exposure measures show a median reduction of 91%. Costs and economic outcome results (mean cost pre- and post-ban, cost-consequences balance sheet and incremental cost per QALYs) are confidential until May 2020 due to their sensitivity and will be available to present at EUPHA 2020.

Conclusions

Previous economic evaluations have focussed on smoking bans in public places and raising the smoking age. This is the first economic analysis of a national prison smoking ban and analysis will be of interest to prison services in other jurisdictions which have yet to implement smokefree policy.

Improving systems of care during and after a pregnancy complicated by hyperglycaemia: A protocol for a complex health systems intervention

BACKGROUND

Many women with hyperglycaemia in pregnancy do not receive care during and after pregnancy according to standards recommended in international guidelines. The burden of hyperglycaemia in pregnancy falls disproportionately upon Indigenous peoples worldwide, including Aboriginal and Torres Strait Islander women in Australia. The remote and regional Australian context poses additional barriers to delivering healthcare, including high staff turnover and a socially disadvantaged population with a high prevalence of diabetes.

METHODS

A complex health systems intervention to improve care for women during and after a pregnancy complicated by hyperglycaemia will be implemented in remote and regional Australia (the Northern Territory and Far North Queensland). The Theoretical Domains Framework was used during formative work with stakeholders to identify intervention components: (1) increasing workforce capacity, skills and knowledge and improving health literacy of health professionals and women; (2) improving access to healthcare through culturally and clinically appropriate pathways; (3) improving information management and communication; (4) enhancing policies and guidelines; (5) embedding use of a clinical register as a quality improvement tool. The intervention will be evaluated utilising the RE-AIM framework at two timepoints: firstly, a qualitative interim evaluation involving interviews with stakeholders (health professionals, champions and project implementers); and subsequently a mixed-methods final evaluation of outcomes and processes: interviews with stakeholders; survey of health professionals; an audit of electronic health records and clinical register; and a review of operational documents. Outcome measures include changes between pre- and post-intervention in: proportion of high risk women receiving recommended glucose screening in early pregnancy; diabetes-related birth outcomes; proportion of women receiving recommended postpartum care including glucose testing; health practitioner confidence in providing care, knowledge and use of relevant guidelines and referral pathways, and perception of care coordination and communication systems; changes to health systems including referral pathways and clinical guidelines.

DISCUSSION

This study will provide insights into the impact of health systems changes in improving care for women with hyperglycaemia during and after pregnancy in a challenging setting. It will also provide detailed information on process measures in the implementation of such health system changes.

What are the perceptions of Indigenous organisation staff on the utility of the nKPIs?

Background

This presentation will outline the results of five Aboriginal Community Controlled Health Organisation (ACCHO) case studies which sought to understand the impact of national key performance indicators (nKPIs) at the local level. The nKPI framework attempts to collect data to assist the Commonwealth Government to monitor the Closing the Gap Framework and to aid local ACCHOs to monitor and review their service delivery. Understanding how the nKPIs have been implemented and their impact across the various sites is essential to understanding their usefulness.

Methods

A multi-case study approach with a variety of ACCHOs was used. Site recruitment was conducted using a purposive sampling framework with an expression of interest, and/or a direct approach. At each site, several semi-structured interviews were conducted, documents were reviewed, and observations made. Data analysis was conducted using the computer program NVivo.

Results

Case studies (n = 5) were conducted at the five sites between in 2017. Data collection included semi-structured interviews ACCHO staff (n = 24), nKPI site-specific documents (n = 12) and observational. A number of key themes emerged from case studies relating to: • Workforce The usefulness of the nKPIsSelf-determinationWay ForwardACCHO Governance

Conclusions

Across the case studies, it is clear there are a variety perception about the utility of the nKPIs and the barriers/enablers which impact their capacity to report, collect and utilise the nKPIs. All Case Study sites saw the value of data to measure their success and to identify emerging issues among their clients. Their attitudes to the nKPIs varied though, due to issues relating to the design and implementation. The stability and size of the service also influenced their ability to use the data. More work needs to be done by the Commonwealth Government in collaboration with ACCHOs to improve the usability and utility of the nKPIs.

Key messages

Indigenous people need to be involved in the design and implmnetation of monitoring sytems. The nKPIs only report on a small subset of services delivered by Aboriginal Community Controlled Health Organisations.
