Increased risk of non-fatal overdose associated with non-prescribed benzodiazepine use in Scotland, UK.

BACKGROUND: Drug-related deaths (DRDs) in Scotland increased for seven years in a row between 2014 and 2020, consolidating Scotland's place at the top of the United Kingdom and European drug-related mortality charts. One of the defining features of this recent and rapid rise has been the role of benzodiazepines, which are now involved in the majority of all DRDs. These deaths are linked to use of non-prescribed, benzodiazepine-type novel psychoactive substances (NPS) which have been identified by the United Nations as a global threat to public health. This study aimed to estimate the prevalence and determinants of non-prescribed benzodiazepine use and its association with recent non-fatal overdose among a national sample of people who inject drugs (PWID). METHODS: Data from the 2019-20 Needle Exchange Surveillance Initiative (NESI) was analysed using logistic regression. NESI is a voluntary, anonymous, biennial, cross-sectional, bio-behavioural survey of PWID attending community-based services providing injecting equipment in mainland Scotland. RESULTS: Prevalence of non-prescribed benzodiazepine use in the past six months was 52% and significantly associated with age (aOR 0.97, 0.96-0.98), frequent incarceration (aOR 1.29, 1.07-1.57), recent public injecting (aOR 3.25, 2.33-4.55), a recent methadone prescription (aOR 1.87, 1.51-2.33), and a history of benzodiazepine prescription (aOR 1.92, 1.47-2.52). In addition, non-prescribed benzodiazepine use was significantly associated with non-fatal overdose in the past year among PWID (aOR 2.47, 1.90-3.21). CONCLUSION: This study found a high prevalence of non-prescribed benzodiazepine use among a national sample of PWID in Scotland. Prevalence was highest among populations known to be at increased risk of drug-related death and use was strongly associated with overdose. These novel findings highlight the scale of the non-prescribed benzodiazepine issue Scotland faces, and the urgency required to expand its harm reduction infrastructure to address this unique element of its overdose crisis.

Recent outbreaks of infectious syphilis, United Kingdom, January 2012 to April 2014.

Six outbreaks of infectious syphilis in the United Kingdom, ongoing since 2012, have been investigated among men who have sex with men (MSM) and heterosexual men and women aged under 25 years. Interventions included case finding and raising awareness among healthcare professionals and the public. Targeting at-risk populations was complicated as many sexual encounters involved anonymous partners. Outbreaks among MSM were influenced by the use of geospatial real-time networking applications that allow users to locate other MSM within close proximity.

Promoting and protecting the health of children and young people.

BACKGROUND: The health-related behaviours adopted by children and young people can have both immediate and long-term health effects. Health promotion interventions that target children and young people can lay the foundations of a healthy lifestyle that may be sustained into adulthood. This paper is based on a selective review of evidence relating to health promotion in childhood, carried out to support the external working group on the 'Healthy Child' module of the Children's National Service Framework. METHODS: This is a selective review of mainly secondary research. It focuses on injury prevention, support for parenting and the promotion of good mental health, and promoting a healthy diet and physical activity amongst children and young people. FINDINGS: In many areas, the quality of primary research into health promotion interventions aimed at children and young people is poor. Interventions are heterogeneous and not described in sufficient detail. Sample sizes tend to be small, and there are commonly problems of bias. Despite these difficulties, there is good evidence for a range of interventions, including (1) area road safety schemes; (2) combining a variety of approaches to the promotion of the use of safety equipment, including legislation and enforcement, loan/assisted purchase/giveaway schemes, education, fitting and maintenance of safety equipment; (3) school-based mental health promotion; (4) parenting support; (5) interventions that promote and facilitate 'lifestyle' activity for children, such as walking and cycling to school, and those that aim to reduce sedentary behaviours such as parent education to reduce the time children spend watching TV and using computers; and (6) controlling advertising of unhealthy food that is aimed at children. CONCLUSIONS: There are effective interventions to promote and protect the health of children and young people that require action across the five areas described in the Ottawa Charter. Health, social care and education services have a direct role in the delivery of many of these interventions and, in other areas, a role in collaborative work with other agencies, in lobbying for policy change and in raising the profile of child health promotion. Further research is needed using larger study populations, and closely defined interventions, both targeted and universal, in order to fill some of the current gaps in the evidence base for health promotion in children and young people.

Practical lessons from the management of an outbreak of small round structured virus (Norwalk-like virus) gastroenteritis.

An outbreak of viral gastroenteritis caused illness in 92 people during October 2000. All the cases had an association with one hotel and 80% of cases identified had attended one of two buffet meals on 18th October 2000. Cohort analysis did not implicate any particular foodstuff in this outbreak. All bacteriological tests on food samples were negative. Small round structured virus (SRSV)/Norwalk-like virus (NLV) particles were seen by electron microscopy in 6 out of 27 stool samples submitted for analysis. This paper describes the outbreak and in particular the lessons learned from the management and control of it. These include practical points with regard to the outbreak control team, liaison with the microbiology laboratory, handling data, agreeing a case definition, and occupational health issues. All can be applied elsewhere by those responsible for managing outbreaks at a local level.

An outbreak of E. coli O157 infection with evidence of spread from animals to man through contamination of a private water supply.

An outbreak of E. coli O157 infection occurred in the Highland Region of Scotland in the summer of 1999. The source of the outbreak was traced to an untreated private water supply. All six cases identified arose in visitors to the area, and most had very limited exposure to the contaminated water. Permanent residents on the same supply were unaffected. The E. coli O157 isolates from the water, sheep faeces collected from around the source and the human stool samples were indistinguishable using pulsed field gel electrophoresis. Previously reported outbreaks of E. coli O157 linked to potable water supplies have resulted from structural or treatment failures, which allowed faecal contamination of source water. Here, contamination of the water supply and subsequent human infection was due to the use of an untreated, unprotected private water source in a rural area where animals grazed freely.

Changes in the pattern of work in a rural community hospital 1987-1997.

OBJECTIVES: To examine time trends in clinical activity at a rural community hospital, and to assess associated changes in the complexity of the care received by inpatients. DESIGN: Descriptive study utilising routine Scottish Morbidity Records data (SMRO1) and locally collected data, along with a retrospective review of admission case notes to quantify clinical inputs to patient care. SETTING: Portree community hospital on the island of Skye. SUBJECTS: Patients admitted to Portree community hospital in 1987, 1992 and 1997. RESULTS: We found an 80 per cent rise in total annual admissions between 1987 and 1997 and a 34 per cent rise in annual casualty attendance between 1992 and 1997. There was a significant reduction in the median duration of in-patient stay, from 8.5 days in 1987 to 6.0 days in 1997. The case-mix of admissions altered significantly between 1992 and 1997. We also demonstrated significant changes in the proportion of patients receiving blood transfusions or intravenous (i.v.) fluids during this time period. CONCLUSIONS: There have been significant changes in the pattern of use of this community hospital over the past 12 years. The rise in total admissions and casualty attendances, combined with the fall in duration of stay reveal an overall increase in activity at the hospital. This has been associated with changes in the clinical spectrum of admissions. Taken together with the results of the workload analysis, it seems likely that the complexity of the clinical input required at the hospital has increased, and that the role of this community hospital is increasingly the provision of intermediate care to acute cases.
