Implementation fidelity matters: Insights from a realist evaluation of police drug diversion schemes in England
Evaluations in the field of police studies do not adequately address implementation fidelity, which impacts understanding of outcomes, how and why an intervention works in practice, what can be done to achieve improvements, and how to implement effective innovations in different contexts. Responding to calls for greater use of implementation science to improve innovations in policing, this article draws on the qualitative phase of a realist, quas…
The effect of a School Street intervention on children’s active travel, satisfaction with their street, and perception of road safety: A natural experimental evaluation
We saw very limited evidence that School Streets affected children's perceptions of feeling safe, liking their school road, identifying themselves as frequent active travellers; there was some evidence for reductions in self-reported active travel. A novel finding is the sense of solidarity and community cohesion that School Streets elicits. A greater understanding of the theory of change and how the intervention works in different areas and affe…

Evaluating police drug diversion in England: Protocol for a realist evaluation
There is increasing international interest in the use of police drug diversion schemes that offer people suspected of minor drug-related offences an educative or therapeutic intervention as an alternative to criminalisation. While there have been randomised trials of some such schemes for their effects on reducing offending, with generally positive results, less is known about the health outcomes, and what works, for whom, in what circumstances a…
Effect of incarceration and opioid agonist treatment transitions on risk of hospitalisation with injection drug use-associated bacterial infections: A self-controlled case series in New South Wales, A…
Risk of injecting-related bacterial infections varies greatly within-individuals over time. Risk is raised immediately after prison release, and around initiation and discontinuation of OAT. Social contextual factors likely contribute to excess risks at transitions in incarceration and OAT exposure
The Frailty, Health and Care Needs Assessment (FHCNA): Development of the questionnaire and testing its feasibility in homeless hostel accommodation
Purpose This study aims to co-develop a Frailty, Health and Care Needs Assessment (FHCNA) questionnaire for people experiencing homelessness and explore the feasibility of its use by non-clinical staff in homeless hostels. Design/methodology/approach The FHCNA, aimed at identifying frailty and other health and care priorities for people experiencing homelessness, was co-designed in workshops (online and in person) with homelessness and inclusion …
Small numbers, big impact: Making a utilitarian case for the contribution of inclusion health to population health in England
Inclusion health groups make up a small proportion of the general population, so despite the extreme social exclusion and poor health outcomes that these groups experience, they are often overlooked in public health investment and policy development. In this paper, we demonstrate that a utilitarian argument can be made for investment in better support for inclusion health groups despite their small size. That is, by preventing social exclusion, t…
Health of people experiencing co-occurring homelessness, imprisonment, substance use, sex work and/or severe mental illness in high-income countries: A systematic review and meta-analysis
Hospital readmission among people experiencing homelessness in England: A cohort study of 2772 matched homeless and housed inpatients
BACKGROUND: Inpatients experiencing homelessness are often discharged to unstable accommodation or the street, which may increase the risk of readmission. METHODS: We conducted a cohort study of 2772 homeless patients discharged after an emergency admission at 78 hospitals across England between November 2013 and November 2016. For each individual, we selected a housed patient who lived in a socioeconomically deprived area, matched on age, sex, h…
Black, Asian and Minority Ethnic groups in England are at increased risk of death from Covid-19: Indirect standardisation of NHS mortality data
Background : International and UK data suggest that Black, Asian and Minority Ethnic (BAME) groups are at increased risk of infection and death from COVID-19. We aimed to explore the risk of death in minority ethnic groups in England using data reported by NHS England. Methods : We used NHS data on patients with a positive COVID-19 test who died in hospitals in England published on 28th April, with deaths by ethnicity available from 1st March 202…
Premature frailty, geriatric conditions and multimorbidity among people experiencing homelessness: A cross-sectional observational study in a London hostel
Purpose The purpose of this paper is to assess frailty, geriatric conditions and multimorbidity in people experiencing homelessness (PEH) using holistic evaluations based on comprehensive geriatric assessment (CGA) and draw comparisons with general population survey data. Design/methodology/approach Cross-sectional observational study conducted in a London-based hostel for single PEH over 30 years old in March–April 2019. The participants and key…

Unravelling the alcohol harm paradox: A population-based study of social gradients across very heavy drinking thresholds
Low socioeconomic status groups are more likely to drink at extreme levels, which may partially explain the alcohol harm paradox. Policies that address alcohol-related health inequalities need to consider extreme drinking levels in some sub-groups that may be associated with multiple markers of deprivation. This will require a more disaggregated understanding of drinking practices
Hugo Ball, Iconoclasm and the Origins of Dada in Zurich
It will be clear to anyone who peruses the vast literature on Dada even casually, or who visited the labyrinthine Dada exhibition at the Centre Pompidou in Paris in 2005–2006,1 that there are almost as many ‘Dadaisms’ as there were Dadaists. Hugo Ball (1886–1927) was a founder, a key theorist and the most self-reflective of the Dadaists in Zurich.2 His Dadaism was deeply ambivalent and contingent. Having opened the Cabaret Voltaire, the much-myth…
