Potential Years of Life Lost Due to Premature Mortality Among Treatment-Seeking Illicit Drug Users in Finland.

Premature death is a serious public health concern. The primary objective of this study was to examine premature deaths in terms of potential years of life lost (PYLL) in a cohort of 4817 treatment-seeking illicit drug users. Clients' data were linked to the Finnish national cause-of-death register and the follow-up period ranged from 31 January 1997 to 31 December 2010. PYLL before 70 years was calculated for all deaths and cause-specific deaths by gender. We observed 496 deaths (417 males and 79 females) at the end of 2010. The mean age at death was 33.8 years, 34.3 years for males (range 18-68) and 31.4 years for females (range 16-53). Overall, 17,951 life years were lost; 14,898 among males and 3053 among females. The overall PYLL rate for males was more than twice that of females (513.0/1000 vs. 243.7/1000 person-years) but the mean PYLL was higher in females than males (38.6 vs. 35.7 years). Of the total PYLL, 34.8 % was due to accidental overdose, and 24.0 % to suicide. In both genders, accidental overdose and suicide were the two top-ranking causes of PYLL. Premature deaths among drug users are a potential loss to the society. Our findings suggest that measures targeting accidental overdose and suicide are top priorities for reducing preventable loss of life.

Coexisting social conditions and health problems among clients seeking treatment for illicit drug use in Finland: the HUUTI study.

BACKGROUND: Illicit drug use is an important public health problem. Identifying conditions that coexist with illicit drug use is necessary for planning health services. This study described the prevalence and factors associated with social and health problems among clients seeking treatment for illicit drug use. METHODS: We carried out cross-sectional analyses of baseline data of 2526 clients who sought treatment for illicit drug use at Helsinki Deaconess Institute between 2001 and 2008. At the clients' first visit, trained clinicians conducted face-to-face interviews using a structured questionnaire. Logistic regression was used to compute adjusted odds ratios (AORs) and 95% confidence intervals (CIs) for factors associated with social and health problems. RESULTS: The mean age of the clients was 25 years, 21% (n = 519) were homeless, 54% (n = 1363) were unemployed and 7% (n = 183) had experienced threats of violence. Half of the clients (50%, n = 1258) were self-referred and 31% (n = 788) used opiates as their primary drugs of abuse. Hepatitis C (25%, n = 630) was more prevalent than other infectious diseases and depressive symptoms (59%, n = 1490) were the most prevalent psychological problems. Clients who were self-referred to treatment were most likely than others to report social problems (AOR = 1.86; 95% CI = 1.50-2.30) and psychological problems (AOR = 1.51; 95% CI = 1.23-1.85). Using opiates as primary drugs of abuse was the strongest factor associated with infectious diseases (AOR = 3.89; 95% CI = 1.32-11.46) and for reporting a combination of social and health problems (AOR = 3.24; 95% CI = 1.58-6.65). CONCLUSION: The existence of illicit drug use with other social and health problems could lead to increased utilisation and cost of healthcare services. Coexisting social and health problems may interfere with clients' treatment response. Our findings support the call for integration of relevant social, medical and mental health support services within drug treatment programmes.

Visual versus written cues: a comparison of drug injectors' responses. Have surveys using the written word underestimated risk behaviors for hepatitis C?

We examined differences in responses of injecting drug users (IDUs) about sharing injecting paraphernalia using written questions ("written cues") versus video recordings of IDUs engaged in sharing behaviors ("visual cues"). Data were collected in 2007 in cities Liverpool, England and Glasgow, Scotland (N = 204). Participants completed a computer-assisted questionnaire with questions about sharing asked using visual and written cues. McNemar's chi-squared tests and logistic regression models were used. Respondents provided significantly different responses to questions about sharing when asked using visual versus written cues; a considerable proportion of IDUs said they had never shared via front/back loading and via sharing water/bleach for flushing out injecting equipment using written cues but confirmed they had participated in these behaviors when asked using visual cues. Implications and future research are discussed.

Drug use and ageing: older people do take drugs!

While usually perceived as behaviour of the young, use of illicit drugs by people aged 50 and over is increasing in Europe and the USA. This increase largely reflects the ageing of general populations, and people who use drugs continuing to do so as they age. For those people dependent upon drugs [usually users of opiates (heroin) and stimulants (cocaine, crack cocaine and amphetamine)], the last 30 years has seen the advent of effective treatment and harm minimisation initiatives and, coupled with general advances in medicine, has increased the life expectancy of these drug users. Drug use by older people presents unique problems; biological systems and processes alter naturally across the life course and the effect of concurrent drug use on some of these systems is not well understood. The natural progression of certain diseases means that symptoms only manifest in older age and the lives of older drug users are likely to be characterised by considerable levels of morbidity. Further work is needed on the epidemiology of drug use by older people--a group of people who currently represent a hidden and vulnerable population.

Self reported health status, and health service contact, of illicit drug users aged 50 and over: a qualitative interview study in Merseyside, United Kingdom.

BACKGROUND: The populations of industrialised countries are ageing; as this occurs, those who continue to use alcohol and illicit drugs age also. While alcohol use among older people is well documented, use of illicit drugs continues to be perceived as behaviour of young people and is a neglected area of research. This is the first published qualitative research on the experiences of older drug users in the United Kingdom. METHODS: Semi-structured interviews were conducted in Merseyside, in 2008, with drug users aged 50 and over recruited through drug treatment services. Interviews were recorded and transcribed and analysed thematically. Only health status and health service contact are reported here. RESULTS: Nine men and one woman were interviewed (age range: 54 to 61 years); all but one had been using drugs continuously or intermittently for at least 30 years. Interviewees exhibited high levels of physical and mental morbidity; hepatitis C was particularly prevalent. Injecting-related damage to arm veins resulted in interviewees switching to riskier injecting practices. Poor mental health was evident and interviewees described their lives as depressing. The death of drug-using friends was a common theme and social isolation was apparent. Interviewees also described a deterioration of memory. Generic healthcare was not always perceived as optimal, while issues relating to drug specific services were similar to those arising among younger cohorts of drug users, for example, complaints about inadequate doses of prescribed medication. CONCLUSION: The concurrent effects of drug use and ageing are not well understood but are thought to exacerbate, or accelerate the onset of, medical conditions which are more prevalent in older age. Here, interviewees had poor physical and mental health but low expectations of health services. Older drug users who are not in contact with services are likely to have greater unmet needs. The number of drug users aged 50 and over is increasing in Europe and America; this group represent a vulnerable, and in Europe, a largely hidden population. Further work to evaluate the impact of this change in demography is urgently needed.

Use, function, and subjective experiences of gamma-hydroxybutyrate (GHB).

Self-reported use of gamma-hydroxybutyrate (GHB) among clubbers has increased over the last decade, and is often reported in the scientific literature in association with negative events such as amnesia, overdose, and use in drug facilitated sexual assault. However, there has been relatively little work investigating the phenomenology of GHB intoxication, and the reasons underlying use. In this study, 189 individuals reporting at least one lifetime use of GHB completed an online questionnaire recording GHB use behaviours, GHB use function, and subjective GHB effects. The most frequently reported primary GHB use functions were for recreation (but not in nightclubs) (18.3%); to enhance sex (18.3%); to be sociable (13.1%); and to explore altered states of consciousness (13.1%). GHB was more commonly used within the home (67%) compared to nightlife environments (26.1%) such as clubs, although this differed on the basis of respondent's sexuality. Principle components analysis of GHB user responses to the subjective questionnaire revealed six components: general intoxication effects, positive intoxication effects, negative intoxication effects, negative physiological effects, positive sexual effects and negative sexual effects. Component scores predicted function of use.

Factors predicting drop out from, and retention in, specialist drug treatment services: a case control study in the North West of England.

BACKGROUND: In the United Kingdom (UK), the National Treatment Agency for Substance Misuse (NTA) considers retention to be the best available measure of drug treatment effectiveness. Accordingly, the NTA has set local treatment systems the annual target of retaining 75% of clients for 12 weeks or more, yet little assessment of this target or factors that improve retention has occurred. This study aims to quantify the proportion of people retained in treatment for 12 weeks in the North West of England and to identify factors associated with premature drop out. METHODS: The North West National Drug Treatment Monitoring System (NDTMS) was used to identify treatment durations for everyone beginning a treatment episode between 1st April 2005 and 31st March 2006 (N = 16626). Odds ratios, chi-square and logistic regression analyses compared clients retained for 12 weeks to clients whose discharge record showed they had prematurely dropped out before 12 weeks. Individuals with other outcomes were excluded from analyses. RESULTS: 75% of clients (N = 12230) were retained for 12 weeks and 10% (N = 1649) dropped out prematurely. Multivariate analysis showed drop out was more likely among Asian drug users (adjusted odds ratio 1.52, 95% CI 1.12 to 2.08) than their white equivalents. Drop out was more likely among residents of Cumbria and Lancashire (adjusted odds ratio 1.80, 95% CI 1.51 to 2.15) and Greater Manchester (adjusted odds ratio 2.00, 95% CI 1.74 to 2.29) than Cheshire and Merseyside and less likely among alcohol users (adjusted odds ratio 0.73, 95% CI 0.59 to 0.91). A significant interaction between age and deprivation was observed. For those aged 18 to 24 years and 25 to 34 years, drop out was significantly more likely among those living in affluent areas. For those in the older age groups the converse effect was observed. CONCLUSION: In combination, the drug treatment systems of the North West achieved the Government's retention target in 2005/06. A number of factors associated with drop out were identified; these should be considered in strategies that aim to improve retention. Drop out and retention are measures that capture the joint effect of many factors. Further work is required to evaluate the effect of deprivation.

The involvement of drugs and alcohol in drug-facilitated sexual assault: a systematic review of the evidence.

The rate of drug-facilitated sexual assault (DFSA; when an incapacitating drug is administered surreptitiously to facilitate sexual assault) is perceived to be increasing in the United Kingdom and elsewhere, causing international concern. This article examines evidence that quantifies the contribution of drugs in instances of alleged DFSA, identifies the substances involved, and discusses the implications of these findings. Of 389 studies examined, 11 were included in this review. The only study to consider covert drugging reported that 2% of alleged DFSA cases were attributable to surreptitious drug administration. Other studies failed to remove voluntary drug consumption from their cohort, biasing results. A study by the United Kingdom's National Forensic Services found no evidence to suggest that flunitrazepam (Rohypnol) had been used for DFSA during its 3-year investigation. In the United States, flunitrazepam is used recreationally, providing a likely explanation for its presence in samples of some alleged DFSA victims.

The impact of citrate introduction at UK syringe exchange programmes: a retrospective cohort study in Cheshire and Merseyside, UK.

BACKGROUND: In 2003, it became legal in the UK for syringe exchange programmes (SEPs) to provide citrate to injecting drug users to solubilise heroin. Little work has been undertaken on the effect of policy change on SEP function. Here, we examine whether the introduction of citrate in Cheshire and Merseyside SEPs has altered the number of heroin/crack injectors accessing SEPs, the frequency at which heroin/crack injectors visited SEPs and the number of syringes dispensed. METHODS: Eleven SEPs in Cheshire and Merseyside commenced citrate provision in 2003. SEP-specific data for the six months before and six months after citrate was introduced were extracted from routine monitoring systems relating to heroin and crack injectors. Analyses compared all individuals attending pre and post citrate and matched analyses only those individuals attending in both periods (defined as 'longitudinal attenders'). Non-parametric tests were used throughout. RESULTS: Neither new (first seen in either six months period) nor established clients visited SEPs more frequently post citrate. New clients collected significantly less syringes per visit post citrate, than pre citrate (14.5,10.0; z = 1.992, P < 0.05). Matched pair analysis showed that the median number of visits for 'longitudinal attenders' (i.e. those who attended in both pre and post citrate periods) increased from four pre citrate to five post citrate (z = 2.187, P < 0.05) but the number of syringes collected remained unchanged. These changes were not due to seasonal variation or other changes in service configuration. CONCLUSION: The introduction of citrate did not negatively affect SEP attendance. 'Longitudinal attenders' visited SEPs more frequently post citrate, providing staff with greater opportunity for intervention and referral. As the number of syringes they collected each visit remained unchanged the total number of clean syringes made available to this group of injectors increased very slightly between the pre and post citrate periods. However, new clients collected significantly less syringes post citrate than pre citrate, possibly due to staff concerns regarding the amount of citrate (and thus syringes) to dispense safely to new clients. These concerns should not be allowed to negatively impact on the number of syringes dispensed.

Hepatitis B vaccination coverage, knowledge and sociodemographic determinants of uptake in high risk public safety workers in Kaduna State, Nigeria: a cross sectional survey.

OBJECTIVES: To estimate hepatitis B vaccination (HBVc) coverage, and knowledge and sociodemographic determinants of full dose uptake in Federal Road Safety Corps (FRSC) members, Kaduna State, Nigeria, to inform relevant targeted vaccination policies. DESIGN: A cross sectional survey of FRSC members, Kaduna Sector Command. SETTINGS: Six randomly selected unit commands under Kaduna Sector Command, Kaduna State, Nigeria. PARTICIPANTS: A pilot tested, structured, self-administered questionnaire was administered to 341 participants aged ≥18 years with ≥6 months of service between 17 June and 22 July 2015. Excluded were FRSC members in road safety 1 zonal command headquarters as the zonal command includes other states beyond the study scope. PRIMARY OUTCOME: HBVc status of participants categorised as 'not vaccinated' for uptake of <3 doses and 'vaccinated' for uptake of ≥3 doses. ANALYSIS: Descriptive analysis estimated HBVc coverage while logistic regression ascertained associations. RESULTS: Most participants were men, aged 30-39 years, with 3-10 years of service and of marshal cadre. HBVc coverage was 60.9% for ≥1 dose and 30.5% for ≥3 doses. Less than 47% of participants scored above the mean knowledge score for hepatitis B virus (HBV) and HBVc. Female sex (AOR 2.28, 95% CI 1.15 to 4.52, p<0.05), perceiving there to be an occupational risk of exposure to HBV (AOR 2.86, 95% CI 1.06 to 7.70, p<0.001) and increasing HBVc knowledge (AOR 2.68, 95% CI 1.83 to 3.92, p<0.001) were independent predictors of full dose HBVc in FRSC members, Kaduna Sector Command. CONCLUSIONS: HBVc coverage and knowledge were poor among FRSC members, Kaduna Sector Command. Educational intervention, geared towards improving FRSC members' knowledge of HBVc and perception of risk of occupational exposure to HBV, is recommended for these vulnerable public safety workers. Such enlightenment could be a cheap and easy way of improving HBVc coverage in the study population.

Trends in drop out, drug free discharge and rates of re-presentation: a retrospective cohort study of drug treatment clients in the North West of England.

BACKGROUND: Governments aim to increase treatment participation by problematic drug users. In the UK this has been achieved by fiscal investment, an expanded workforce, reduced waiting times and coercive measures (usually criminal justice (CJ) led). No assessment of these measures on treatment outcomes has been made. Using established monitoring systems we assessed trends in 'dropped out' and 'discharged drug free' (DDF), since the launch of the national drug strategy, and rates of treatment re-presentation for these cohorts. METHODS: A longitudinal dataset of drug users (1997 to 2004/05, n = 26,415) was used to identify people who dropped out of, and were DDF from, services for years 1998 to 2001/02, and re-presentations of these people in years to 2004/05. Trends in drop out and DDF, baseline comparisons of those DDF and those who dropped out and outcome comparisons for those referred from the CJ system versus other routes of referral were examined using chi square. Logistic regression analyses identified variables predicting drop out versus DDF and subsequent re-presentation versus no re-presentation. RESULTS: The proportion of individuals dropping out has increased from 7.2% in 1998 to 9.6% in 2001/02 (P < 0.001). The proportion DDF has fallen from 5.8% to 3.5% (P < 0.001). Drop out was more likely in later years, by those of younger age and by CJ referrals. The proportion re-presenting to treatment in the following year increased from 27.8% in 1998 to 44.5% in 2001/02 (P < 0.001) for those DDF, and from 22.9% to 48.6% (P < 0.001) for those who dropped out. Older age and prior treatment experience predicted re-presentation. Outcome (drop out or DDF) did not predict re-presentation. CONCLUSION: Increasing numbers in treatment is associated with an increased proportion dropping out and an ever-smaller proportion DDF. Rates of drop out are significantly higher for those coerced into treatment via the CJ system. Rates of re-presentation are similar for those dropping out and those DDF. Encouragingly, those who need to re-engage with treatment, particularly those who drop out, are doing so more quickly. The impact of coercion on treatment outcomes and the appropriateness of aftercare provision require further consideration.

Hospitalization in a cohort seeking treatment for illicit drug use in Finland.

Illicit drug use is associated with various health problems that result in inpatient hospital admissions. The primary objective of this study was to examine all-cause and cause-specific hospitalizations by gender. The cohort comprised 4817 drug users (3365 males and 1452 females) who sought treatment in Helsinki between 1997 and 2008. Data on hospitalizations that occurred among these clients were extracted from the National Hospital Discharge Register. Crude hospitalization rates (CHRs) and standardized hospitalization ratios (SHRs) with 95% confidence intervals (CIs) were calculated, and Kaplan-Meier analysis with Log-Rank test was used to compare survival in terms of time to hospitalization between males and females. At the end of the follow-up period, 84.5% of females and 73.3% of male clients were hospitalized at least once. Female clients had higher CHR (607.6/1000 person-years, 95%CI: 594.1-621.4) than males (511.0/1000, 95% CI: 502.9-519.3), and had significantly poorer survival than males (Log-Rank test, P<0.001). However, male clients stayed longer on admission than females (mean length of stay 70.2days versus 60.7days respectively, P<0.001). Compared to the national rates, excess hospitalizations were noted in both males (SHR=6.3, 95% CI: 6.2-6.4) and female clients (SHR=4.3, 95% CI: 4.2-4.4). Based upon primary discharge diagnosis, the leading causes of hospitalizations included psychosis (n=622), schizophrenia (n=604), depression (n=497), cardiovascular diseases (n=223), hepatitis C (n=116), HIV (n=81), and other types of hepatitis (n=45). Female clients were more likely than males to be admitted for hepatitis C infection (P<0.001) and depression (P<0.001). Male clients were more likely than females to be diagnosed with other types of hepatitis infections (P=0.032) and psychosis (P=0.035). Excess hospitalizations signify excessive utilization of health resources. Effective drug abuse treatment, gender-sensitive approaches, and regular health checks can help to reduce morbidity. Appropriate measures are needed to address psychiatric problems in this population.

Factors associated with hospitalization for blood-borne viral infections among treatment-seeking illicit drug users.

Blood-borne viral infections (BBVIs) are important health consequences of illicit drug use. This study assessed predictors of inpatient hospital admissions for BBVIs in a cohort of 4817 clients seeking treatment for drug use in Finland. We examined clients' data on hospital admissions registered in the Finnish National Hospital Discharge Register from 1997 to 2010 with diagnoses of BBVIs. Cox proportional hazards regression analyses were separately conducted for each of the three BBVI groups to test for association between baseline variables and hospitalizations. Findings were reported as adjusted hazard ratios (aHRs). Based upon primary discharge diagnoses, 81 clients were hospitalized for HIV, 116 for hepatitis C, and 45 for other types of hepatitis. Compared to those admitted for hepatitis C and other hepatitis, drug users with HIV had higher total number of hospital admissions (294 versus 141 and 50 respectively), higher crude hospitalization rate (7.1 versus 3.4.and 1.2 per 1000 person-years respectively), and higher total length of hospital stay (2857 days versus 279 and 308 respectively). Trends in hospitalization for all BBVI groups declined at the end of follow-up. HIV positive status at baseline (aHR: 6.58) and longer duration of drug use (aHR: 1.11) were independently associated with increased risk for HIV hospitalization. Female gender (aHR: 3.05) and intravenous use of primary drug (aHR: 2.78) were significantly associated with HCV hospitalization. Having hepatitis B negative status at baseline (aHR: 0.25) reduced the risk of other hepatitis hospitalizations. Illicit drug use coexists with blood-borne viral infections. To address this problem, clinicians treating infectious diseases need to also identify drug use in their patients and provide drug treatment information and/or referral.

Patterns and 14-year trends in mortality among illicit drug users in Finland: the HUUTI study.

BACKGROUND: Although mortality is a known complication of illicit drug use, robust epidemiological studies on drug-related mortality in Finland are scarce. We examined all deaths, specific causes of death, and trends in mortality among a large number of illicit drug users in Finland during a 14-year period. METHODS: Details of 4817 clients who sought treatment for drug use at Helsinki Deaconess Institute between 1997 and 2008 were linked to national cause of death register to identify all deaths and causes of death. Standardised mortality ratios (SMRs) were calculated to compare all-cause deaths in our study cohort with those in the general population. Trends in mortality rates were assessed using Poisson (log-linear) regression. RESULTS: A total of 496 deaths occurred during 41,567.5 person-years with crude mortality rate of 1193.2 per 100,000 person-years. Mean follow-up was 8.6 years and the mean age at death was 33.8 years. Most deaths (84.1%) occurred among male clients, 189 deaths occurred in the 25-34 age-group and all-cause SMR was 8.9 [95% confidence interval (CI)=8.1-9.7]. Two-thirds (64.9%) were deaths from external causes and 35.1% from disease-related causes. The four leading causes of death were accidental poisoning/overdose (n=165), suicide (n=108), mental and behavioural disorders (n=49) and circulatory system diseases (n=45). Younger clients died from acute effects of drug use while older clients died more from chronic health conditions. A decline in annual rates was noted for all-cause mortality (P=0.01), deaths from mental and behavioural disorders (P<0.001) and suicides (P<0.001). CONCLUSION: The four leading causes of death among illicit drug users are preventable. Overdose management training, drug education and other preventive measures could help reduce mortality.

Deaths ascribed to non-communicable diseases among rural Kenyan adults are proportionately increasing: evidence from a health and demographic surveillance system, 2003-2010.

BACKGROUND: Non-communicable diseases (NCDs) result in more deaths globally than other causes. Monitoring systems require strengthening to attribute the NCD burden and deaths in low and middle-income countries (LMICs). Data from health and demographic surveillance systems (HDSS) can contribute towards this goal. METHODS AND FINDINGS: Between 2003 and 2010, 15,228 deaths in adults aged 15 years (y) and older were identified retrospectively using the HDSS census and verbal autopsy in rural western Kenya, attributed into broad categories using InterVA-4 computer algorithms; 37% were ascribed to NCDs, 60% to communicable diseases (CDs), 3% to injuries, and <1% maternal causes. Median age at death for NCDs was 66y and 71y for females and males, respectively, with 43% (39% male, 48% female) of NCD deaths occurring prematurely among adults aged below 65y. NCD deaths were mainly attributed to cancers (35%) and cardio-vascular diseases (CVDs; 29%). The proportionate mortality from NCDs rose from 35% in 2003 to 45% in 2010 (χ2 linear trend 93.4; p<0.001). While overall annual mortality rates (MRs) for NCDs fell, cancer-specific MRs rose from 200 to 262 per 100,000 population, mainly due to increasing deaths in adults aged 65y and older, and to respiratory neoplasms in all age groups. The substantial fall in CD MRs resulted in similar MRs for CDs and NCDs among all adult females by 2010. NCD MRs for adults aged 15y to <65y fell from 409 to 183 per 100,000 among females and from 517 to 283 per 100,000 population among males. NCD MRs were higher among males than females aged both below, and at or above, 65y. CONCLUSIONS: NCDs constitute a significant proportion of deaths in rural western Kenya. Evidence of the increasing contribution of NCDs to overall mortality supports international recommendations to introduce or enhance prevention, screening, diagnosis and treatment programmes in LMICs.

Exercise referral for drug users aged 40 and over: results of a pilot study in the UK.

OBJECTIVES: To test whether older drug users (aged 40 and over) could be recruited to an exercise referral (ER) scheme, to evaluate the feasibility and acceptability and measure the impact of participation on health. DESIGN: Observational pilot. SETTING: Liverpool, UK. PARTICIPANTS: (1) 12 men and 5 women recruited to ER. (2) 7 specialist gym instructors. OUTCOME MEASURES: Logistic feasibility and acceptability of ER and associated research, rate of recruitment, level of participation over 8 weeks and changes in health. RESULTS: 22 gym inductions were arranged (recruitment time: 5 weeks), 17 inductions were completed and 14 participants began exercising. Attendance at the gym fluctuated with people missing weeks then re-engaging; in week 8, seven participants were in contact with the project and five of these attended the gym. Illness and caring responsibilities affected participation. Participants and gym instructors found the intervention and associated research processes acceptable. In general, participants enjoyed exercising and felt fitter, but would have welcomed more support and the offer of a wider range of activities. Non-significant reductions in blood pressure and heart rate and improvements in metabolic equivalents (METs; a measure of fitness) and general well-being were observed for eight participants who completed baseline and follow-up assessments. The number of weeks of gym attendance was significantly associated with a positive change in METs. CONCLUSIONS: It is feasible to recruit older drug users into a gym-based ER scheme, but multiple health and social challenges affect their ability to participate regularly. The observed changes in health measures, particularly the association between improvements in METs and attendance, suggest further investigation of ER for older drug users is worthwhile. Measures to improve the intervention and its evaluation include: better screening, refined inclusion/exclusion criteria, broader monitoring of physical activity levels, closer tailored support, more flexible exercise options and the use of incentives.

Prevalence of, and risk factors for, HIV, hepatitis B and C infections among men who inject image and performance enhancing drugs: a cross-sectional study.

OBJECTIVE: To describe drug use, sexual risks and the prevalence of blood-borne viral infections among men who inject image and performance enhancing drugs (IPEDs). DESIGN: A voluntary unlinked-anonymous cross-sectional biobehavioural survey. SETTING: 19 needle and syringe programmes across England and Wales. PARTICIPANTS: 395 men who had injected IPEDs. RESULTS: Of the participants (median age 28 years), 36% had used IPEDs for <5 years. Anabolic steroids (86%), growth hormone (32%) and human chorionic gonadotropin (16%) were most frequently injected, with 88% injecting intramuscularly and 39% subcutaneously. Two-thirds also used IPEDs orally. Recent psychoactive drug use was common (46% cocaine, 12% amphetamine), 5% had ever injected a psychoactive drug and 9% had shared injecting equipment. 'Viagra/Cialis' was used by 7%, with 89% reporting anal/vaginal sex in the preceding year (20% had 5+ female-partners, 3% male-partners) and 13% always using condoms. Overall, 1.5% had HIV, 9% had antibodies to the hepatitis B core antigen (anti-HBc) and 5% to hepatitis C (anti-HCV). In multivariate analysis, having HIV was associated with: seeking advice from a sexual health clinic; having had an injection site abscess/wound; and having male partners. After excluding those reporting male partners or injecting psychoactive drugs, 0.8% had HIV, 8% anti-HBc and 5% anti-HCV. Only 23% reported uptake of the hepatitis B vaccine, and diagnostic testing uptake was poor (31% for HIV, 22% for hepatitis C). CONCLUSIONS: Previous prevalence studies had not found HIV among IPED injectors. HIV prevalence in this, the largest study of blood-borne viruses among IPED injectors, was similar to that among injectors of psychoactive drugs. Findings indicate a need for targeted interventions.

Trauma-related mortality among adults in Rural Western Kenya: characterising deaths using data from a health and demographic surveillance system.

BACKGROUND: Information on trauma-related deaths in low and middle income countries is limited but needed to target public health interventions. Data from a health and demographic surveillance system (HDSS) were examined to characterise such deaths in rural western Kenya. METHODS AND FINDINGS: Verbal autopsy data were analysed. Of 11,147 adult deaths between 2003 and 2008, 447 (4%) were attributed to trauma; 71% of these were in males. Trauma contributed 17% of all deaths in males 15 to 24 years; on a population basis mortality rates were greatest in persons over 65 years. Intentional causes accounted for a higher proportion of male than female deaths (RR 2.04, 1.37-3.04) and a higher proportion of deaths of those aged 15 to 65 than older people. Main causes in males were assaults (n=79, 25%) and road traffic injuries (n=47, 15%); and falls for females (n=17, 13%). A significantly greater proportion of deaths from poisoning (RR 5.0, 2.7-9.4) and assault (RR 1.8, 1.2-2.6) occurred among regular consumers of alcohol than among non-regular drinkers. In multivariate analysis, males had a 4-fold higher risk of death from trauma than females (Adjusted Relative Risk; ARR 4.0; 95% CI 1.7-9.4); risk of a trauma death rose with age, with the elderly at 7-fold higher risk (ARR 7.3, 1.1-49.2). Absence of care was the strongest predictor of trauma death (ARR 12.2, 9.4-15.8). Trauma-related deaths were higher among regular alcohol drinkers (ARR 1.5, 1.1-1.9) compared with non-regular drinkers. CONCLUSIONS: While trauma accounts for a small proportion of deaths in this rural area with a high prevalence of HIV, TB and malaria, preventive interventions such as improved road safety, home safety strategies for the elderly, and curbing harmful use of alcohol, are available and could help diminish this burden. Improvements in systems to record underlying causes of death from trauma are required.

When is a drug-related death not a drug-related death? Implications for current drug-related death policies in the UK and Europe.

BACKGROUND: Drug-related death (DRD) figures, published by the national performance management framework, are used to monitor the performance of Drug (and Alcohol) Action Teams (D[A]ATs) in England and Wales with respect to reducing DRDs among drug abusers. To date, no investigation has been made into the types of death included in these figures, the demographic and drug profile of those who died, nor the likelihood of individuals included in DRD figures interacting with services designed to assist drug abusers. The aim of this work was to examine the characteristics of deaths classified as drug-related and to explore their applicability to performance-monitor drug-related services. Liverpool was chosen because it was reported by the national DRD monitoring system to have the highest number of DRDs in 2004. METHODS: Information was retrieved from the Liverpool coroner's records and established monitoring systems on individuals reported by the national performance monitoring system as a DRD between 1st January 2004 and 30th June 2005 (n = 70). Analyses assessed differences between those categorised by the national performance monitoring system as 'drug abusers/dependents' and 'non-drug abusers/dependents' using chi2, Fisher's exact test and Mann-Whitney U. RESULTS: Non-drug abusers were significantly older (median age 53.59 vs. 38.23), had no recent contact with drug-related agencies (cv. 31.6% of abusers who had treatment contact) and had different post mortem drug profiles than drug abusers. A significantly greater proportion of non-drug abusers died from drug toxicity - predominantly through anti-depressants, anti-psychotics and analgesics. CONCLUSION: Our findings suggest that the national DRD performance monitoring system includes deaths of people who are not drug abusers - individuals who are not the current focus of drug prevention, treatment or harm minimisation services. This raises concerns regarding the applicability of these figures to performance monitor D(A)ATs. Furthermore, using the more compact definitions used to monitor trends in DRDs across England, Wales and Europe fails to include a proportion of deaths attributable to drug misuse - such as those attributable blood-borne viruses. Current definitions used to monitor DRDs locally, nationally and across Europe fail to capture the true burden of drug-related mortality.
