Diagnosis and management of tuberculosis infection in inclusion health populations in London.

BACKGROUND: Tuberculosis in the UK is more prevalent in people with social risk factors- e.g. previous incarceration, homelessness - and in migrants from TB endemic countries. The management of TB infection is part of TB elimination strategies, but is challenging to provide to socially excluded groups and the evidence base for effective interventions is small. METHODS: We evaluated a TB infection screening and treatment programme provided by a peer-led service (Find&Treat) working in inclusion health settings (e.g. homeless hostels) in London. IGRA (interferon-gamma release assay) testing and TB infection treatment were offered to eligible adults using a community-based model. The primary outcome was successful progression through the cascade of care. We also evaluated socio-demographic characteristics associated with a positive IGRA. RESULTS: 42/312 (13.5%) participants had a positive IGRA and no one had evidence of active TB. 35/42 completed a medical evaluation; 22 started treatment, and 17 completed treatment. Having a positive IGRA was associated with previous incarceration and being born outside of the UK. DISCUSSION: Provision of TB infection diagnosis and management to this socially excluded population has several challenges including maintaining people in care and drug-drug interactions. Peer-support workers provided this service safely and effectively with appropriate support. Further work to generate data to inform risks and benefits of treatment for TB infection in this group is needed to facilitate joint decision making.

Interventions to improve health and the determinants of health among sex workers in high-income countries: a systematic review.

Many sex worker populations face high morbidity and mortality, but data are scarce on interventions to improve their health. We did a systematic review of health and social interventions to improve the health and wider determinants of health among adult sex workers in high-income countries. We searched MEDLINE, Embase, PsycINFO, CINAHL, the Cochrane Library, Web of Science, EthOS, OpenGrey, and Social Care Online, as well as the Global Network of Sex Work Projects and the Sex Work Research Hub for studies published between Jan 1, 2005 and Dec 16, 2021 (PROSPERO CRD42019158674). Quantitative studies reporting disaggregated data for sex workers were included and no comparators were specified. We assessed rigour using the Quality Assessment Tool for Quantitative Studies. We summarised studies using vote counting and a narrative synthesis. 20 studies were included. Most reported findings exclusively for female sex workers (n=17) and street-based sex workers (n=11). Intervention components were divided into education and empowerment (n=14), drug treatment (n=4), sexual and reproductive health care (n=7), other health care (n=5), and welfare (n=5). Interventions affected a range of mental health, physical health, and health behaviour outcomes. Multicomponent interventions and interventions that were focused on education and empowerment were of benefit. Interventions that used peer design and peer delivery were effective. An outreach or drop-in component might be beneficial in some contexts. Sex workers who were new to working in an area faced greater challenges accessing services. Data were scarce for male, transgender, and indoor-based sex workers. Co-designed and co-delivered interventions that are either multicomponent or focus on education and empowerment are likely to be effective. Policy makers and health-care providers should improve access to services for all genders of sex workers and those new to an area. Future research should develop interventions for a greater diversity of sex worker populations and for wider health and social needs.

The ACE Index: mapping childhood adversity in England.

BACKGROUND: Studies of adults show that adverse childhood experiences (ACEs) are associated with health and social problems and are more common among people living in deprived areas. However, there is limited information about the geographical pattern of contemporary ACEs. METHODS: We used data from the police, social services, schools and vital statistics in England to calculate population rates of events that represent childhood adversity. We constructed an 'ACE Index' that summarizes the relative frequency of ACEs at local authority level, informed by the methods of the Index of Multiple Deprivation. We explored associations between the ACE Index and local characteristics in cross-sectional ecological analysis. RESULTS: The ACE Index was strongly associated with the proportion of children that live in income-deprived households (child poverty). In addition, the ACE Index was independently associated with higher population density and was higher in certain regions, particularly the north-east. CONCLUSIONS: The association between ACEs and child poverty provides evidence of a process in which deprivation increases the risk of adverse experiences in childhood. The ACE Index can inform allocation of resources for prevention and mitigation of ACEs.

An audit of tuberculosis health services in prisons and immigration removal centres.

Background: Tuberculosis (TB) is the second leading cause of death worldwide due to a single infectious agent. Rates of active TB in places of prescribed detention (PPD), which include Prisons, Young Offender Institutions and Immigration Removal Centres, are high compared with the general population. PPD therefore present an opportunity to develop targeted health programmes for TB control. This audit aims to assess current service provisions and identify barriers to achieving best practice standards in PPD across London. Methods: Twelve healthcare teams within PPD commissioned by NHS England (London Region) were included in the audit. Services were evaluated against the National Institute for Health and Care Excellence standards for TB best practice. Results: None of the health providers with a digital X-ray machine were conducting active case finding in new prisoners and no health providers routinely conduct Latent TB infection testing and preventative treatment. Barriers to implementing standards include the lack of staff skills and staff skills mix, structural and technical barriers, and demands of custodial and health services. Conclusions: This audit restates the importance of national public health TB strategies to consider healthcare provisions across PPD.
