Implementing routine blood-borne virus testing for HCV, HBV and HIV at a London Emergency Department - uncovering the iceberg?

UK guidelines recommend routine HIV testing in high prevalence emergency departments (ED) and targeted testing for HBV and HCV. The 'Going Viral' campaign implemented opt-out blood-borne virus (BBV) testing in adults in a high prevalence ED, to assess seroprevalence, uptake, linkage to care (LTC) rates and staff time taken to achieve LTC. Diagnosis status (new/known/unknown), current engagement in care, and severity of disease was established. LTC was defined as patient informed plus ⩾1 clinic visit. A total of 6211/24 981 ED attendees were tested (uptake 25%); 257 (4.1%) were BBV positive (15 co-infected), 84 (33%) required LTC. 100/147 (68%) HCV positives were viraemic; 44 (30%) required LTC (13 new, 16 disengaged). 26/54 (48%) HBV required LTC (seven new, 11 disengaged). 16/71 (23%) HIV required LTC (10 new, five disengaged). 26/84 (31%) patients requiring LTC had advanced disease (CD4 1, Fibroscan F3/F4 or liver cancer), including five with AIDS-defining conditions and three hepatocellular carcinomas. There were five BBV-related deaths. BBV prevalence was high (4.1%); most were HCV (2.4%). HIV patients were more successfully and quickly LTC than HBV or HCV patients. ED testing was valuable as one-third of those requiring LTC (new, disengaged or unknown status patients) had advanced disease.

A public health needs assessment for domestic indoor overheating.

OBJECTIVES: Indoor overheating is a potentially fatal health hazard that was identified as an issue requiring urgent action in the 2017 UK Climate Change Risk Assessment. We aimed to make research on this issue more accessible to local public health teams to encourage its inclusion in local strategic needs assessments. STUDY DESIGN: Epidemiological health needs assessment. METHODS: We adapted established health needs assessment methods, focussing on the epidemiological component, drawing evidence from a non-systematic literature review that was complemented by discussion with experts. RESULTS: Indoor overheating arises from an interaction between occupants' susceptibility to heat, their behaviour and the building's location and its characteristics. Many of these factors are interrelated and, at a national level, are expected to vary over time with demographic and climate change. Understanding these factors, ways to mitigate them and a long-term view are all essential for managing overheating risk. CONCLUSIONS: There is a need for services to be provided at the local level that consider the home environment and its impact on health in all seasons. A population-level approach to risk management across a local area is also useful to inform collaborative efforts to reduce future incidence of overheating and better understand how it varies with socio-economic deprivation.
