Subjective sleep-wake parameters in treatment-seeking opiate addicts.

We investigated subjective sleep parameters and sleep difficulties of opiate addicts undertaking methadone detoxification and identified their sleep profile. Using the St Marys Sleep Questionnaire, we compared the subjective sleep parameters of 27 consecutively consenting patients (16 males, 11 females) with a mean age of 33 years (S.D. = 7.5) undertaking in-patient methadone detoxification with those of 26 drug-free controls (9 males, 17 females) with a mean age of 35 years (S.D. = 8.0). Our findings reveal that subjective sleep parameters of opiate addicts and controls are quantitatively and qualitatively different. The patients are more likely than controls to report difficulty initiating sleep (OR = 5.42; 95% CI = 1.43, 20.47); difficulty maintaining sleep (OR = 16.50; 95% CI = 3.81, 71.47); inadequate sleep quality (OR = 8.56; 95% CI = 2.04, 35.81); and inadequate sleep quantity (OR = 9.00; 95% CI = 2.49, 32.57).

Drug abuse-related mortality: a study of teenage addicts over a 20-year period

Background: There is growing concern about increase in illicit drug use and associated fatalities in young people. Method: This longitudinal analysis of successive cohorts of addicts in England and Wales aged 15–19 years followed up over a 20-year period covering 1974 to 1993 (1) investigated trends in all-causes mortality; (2) examined teenage-specific mortality, i.e. deaths during ages 15–19 years; (3) determined excess teenage-specific mortality; and (4) identified the main underlying causes of teenage-specific death in this population. The main outcome measures were overall mortality rates, teenage-specific mortality and standardised mortality ratios calculated for four 5-year (period) successive cohorts. Results: Overall mortality rate in the study population (N = 9491) was 4.7/1000 person-years. The median age at death was 23 years (semi interquartile range = 3), with the majority (91.3%) of deaths occurring between ages 15 and 29 years. Excess teenage-specific mortality in the population was 10.7 in males and 21.2 in females (general population = 1), and increase in excess mortality in both sexes was evident in the last 5-year period of study. The majority of deaths (64.3%) resulted from accidental poisoning. Methadone and heroine/morphine accounted for about two-thirds of accidental poisoning deaths, while suicide accounted for 11.4% of teenage-specific deaths. Conclusions: It is strongly recommended that treatment services should be more responsive to the need for careful prescribing, dispensing and administration of substitute medication to teenage addicts in their care. The development of needs-led, case-sensitive treatment services for young addicts is indicated.

Overview of Amphetamine-Type Stimulant Mortality Data – UK, 1997–2007

Background/Aims: Despite being amphetamine derivatives, MDMA and its analogues show a number of clinical pharmacological differences with respect to both amphetamine (AMP) and methylamphetamine (METH). We aimed here at reporting and analysing information relating to the socio-demographics and clinical circumstances of the AMP-type stimulant-related deaths for the whole of the UK. Methods: Data (1997–2007) were taken from the National Programme on Substance Abuse Deaths (np-SAD) database, collecting information from UK coroners/procurators fiscal. To calculate rates of fatalities per 100,000 users, appropriate AMP/METH and ecstasy users’ numbers were taken from the 2001–2007 British Crime Survey. Results: Overall, 832 AMP/METH- and 605 ecstasy (mostly MDMA and methylenedioxyamphetamine/MDA)-related deaths were respectively identified. In comparison with AMP/METH victims, the ecstasy ones were more likely to be younger (28.3 vs. 32.7 years; p < 0.0001) and less likely to be known as drug users (PR = 1.9; CI 1.5–2.6). Ecstasy was more likely to be identified on its own than AMP/METH (p = 0.0192). Contributory factors were more frequently mentioned by coroners in the ‘AMP/METH-only’ (106 cases) group than in the ‘ecstasy-only’ (104 cases) one (p = 0.0043). Both poly- and monodrug AMP/METH fatalities per 100,000 16- to 59-year-old users were significantly more represented than ecstasy fatalities (respectively 17.87 ± 4.77 deaths vs. 10.89 ± 1.27; p = 0.000; 2.09 ± 0.88 vs. 1.75 ± 0.56; p = 0.0096). However, mono-intoxication ecstasy fatalities per 100,000 16- to 24-year-old users were significantly more represented than AMP/METH fatalities (1.67 ± 0.52 vs. 0.8 ± 0.65; p = 0.0007). Conclusion: With respect to AMP/METH, ecstasy was here more typically identified in victims who were young, healthy, and less likely to be known as drug users. AMP/METH high mortality rates may be explained by users’ high levels of physical co-morbidity; excess ecstasy-related fatality rates in young users may be a reason for concern. Although the coroners’ response rate was of 90–95%, study limitations include both reporting inconsistency over time and lack of routine information on drug intake levels prior to death.

Delayed sleep phase in severe obsessive-compulsive disorder: a systematic case-report survey.

INTRODUCTION To study the prevalence of delayed sleep phase (DSP) in a cohort of inpatients with severe obsessive-compulsive disorder (OCD) and to identify clinical and demographic correlates. METHODS A systematic retrospective case-report study of consecutive OCD admissions to a specialist inpatient unit from January 1995 to December 2003. Nursing and medical records of sleep, demographic, clinical, and other relevant details were recorded. RESULTS Of 194 eligible consecutive case reports, 187 were located, and nursing and medical reports of sleep were identified in all 187 (100%). Thirty-three patients (17.6%) fulfilled operationally defined criteria for DSP after exclusion of possible confounding factors. All the patients with DSP were unemployed. Phase-shifted patients were significantly younger than non-shifted patients (P=.019) and reported an earlier age of onset of their OCD (P=.005). There was a non-significant trend toward more severe OCD in the phase-shifted group, but they were not more depressed than their non-shifted counterparts. CONCLUSION A substantial number of patients with severe, enduring OCD also suffer with DSP, which seems to be specifically linked to OCD as opposed to comorbid depression. Clarification of the etiology within DSP and its interaction with core OCD symptoms on clinical function and disability may identify new treatment targets. To this end, further studies of sleep in OCD using actigraphy and biological measures are indicated.

A Pilot Study Examining Gambling Behaviour Before and After the Launch of the National Lottery and Scratch Cards in the UK

This study monitored gambling behaviour in 206 residents of Cambridgeshire before and after the launch of United Kingdoms National Lottery. A Gambling questionnaire which included the gambling criteria from the Diagnostic Statistical Manual-IV. questions about demographic data, and National Lottery and scratch cards purchases was administered randomly to residents in Cambridgeshire. The study found that the affirmative responses in the DSM-IV criteria increased significantly at 6 months after the introduction of the National Lottery and remained at that level at the 12 month follow up. Although symptoms of pathological gambling rose, there was no increase in cases of pathological gamblers. Furthermore, individuals with annual household incomes of less than £ 20.000 and individuals with less than an O level education purchased more National Lottery tickets and scratch cards per week. This may suggest that these people may be vulnerable to develop problems with lottery and scratch card play.

The effectiveness of behavioural interventions in the primary prevention of Hepatitis C amongst injecting drug users: a randomised controlled trial and lessons learned

AimTo develop and evaluate the comparative effectiveness of behavioural interventions of enhanced prevention counselling (EPC) and simple educational counselling (SEC) in reducing hepatitis C viral (HCV) infection in sero-negative injecting drug users (IDU).DesignRandomised controlled trial (RCT) of EPC intervention in comparison with simple educational counselling (SEC).Setting SpecialisedDrug services in London and Surrey, United Kingdom.Participants and MeasurementsNinety five IDUs were recruited and randomised to receive EPC (n = 43) or SEC (n = 52). Subjects were assessed at baseline using the Addiction Severity Index (ASI), the Injecting Risk Questionnaire (IRQ), and Drug Injecting Confidence Questionnaire (DICQ). The primary outcome was measured by the rate of sero-conversion at 6 months and 12 months from baseline and by the ASI, IRQ and DICQ at 6 months from baseline. Hepatitis C testing was undertaken by the innovative test of the dried blood spot (DBS) test which increased the rate of testing by 4 fold compared to routine blood testing.Findings SeventyEighty two subjects (82%) out of the 95 recruited were followed up at 6 months and 62 (65%) were followed up at 12 months. On the primary outcome measure of the rate of seroconversion, 8 out of 62 patients followed-up at twelve months seroconverted, three in the EPC group and five in the SEC group, indicating incidence rates of 9.1 per 100 person years for the EPC group, 17.2 per 100 person years for the SEC group, and 12.9 per 100 person years for the cohort as a whole. Analysis of the secondary outcome measures on alcohol use, risk behaviour, psychological measures, quality of life, showed no significant differences between the EPC and the SEC groups. However, there were significant changes on a number of measures from baseline values indicating positive change for both groups.ConclusionWe were not able to prove the efficacy of EPC in comparison with SEC in the prevention of hepatitis C in IDUs. This was related to low recruitment and retention rates of the participants. Moreover there was a low adherence rate to EPC. The study provided the benefits of developing and introducing behavioural interventions of the EPC and SEC and the DBS screening for Hepatitis C. Moreover the main lessons learnt were that piloting of a new intervention is a crucial first step before conducting pragmatic RCTs of psychological interventions in the field of addiction; that an infrastructure and culture for psychosocial interventions is needed to enable applied research in the service environment, and research funding is needed for enabling the recruitment of dedicated trained therapists for the delivery of these interventions.

Substance use in the general hospital.

INTRODUCTION People misusing substances are overrepresented in health settings. Substance misuse can also be an underlying factor complicating medical diagnosis and management. AIMS (i) To establish the prevalence of substance misuse in the general hospital inpatient population; and (ii) to examine the relationship between medical diagnosis and substance misuse problem as identified by screening tools. METHOD This study adopted a three-step screening approach including a prospective questionnaire survey, interview, and case note review. Subjects included all adult patients admitted to a London teaching hospital over a 1-week period. RESULTS Seventy percent completed the questionnaire. Twenty-three percent was currently smoking, 14% was rated positive for alcohol misuse, and 12% positive for drug misuse. Only 65% of patients was screened for smoking, 54% for alcohol, and 9% for other substances. CONCLUSIONS People misusing one substance were more likely to be misusing others, hence the importance of screening all patients for all substances. Doctors were screening a small percentage of patients and they identified and intervened with only the severe ones.

Tsunami: understanding mental health consequences and the unprecedented response.

The 26th December 2004 saw a disaster brought on by massive waves – the Asian Tsunami. Millions of people died or were affected to varying degrees. The mental health aftermath did not only hit the Tsunami affected areas but it also sent ripples globally. Financial and humanitarian aid was overwhelming. This review brings together the mental health consequences and the global response. It provides a systematic overview of the mental health problems both within the affected areas and globally. It considers different levels and intensities of mental health problems both in affected areas and globally and explores the effects on vulnerable groups. It describes the unprecedented response and highlights the importance of providing culturally and contextually sensitive, integrated and co-ordinated interventions, informed by qualitative and quantitative assessment of needs, urgency and resource availability. The review also provides a retrospective view on the drivers of such a response.

Watching internet pharmacies

The number of illegal internet pharmacies selling prescription-only medicines without a prescription is increasing. Large quantities of drugs are dispensed, making drugs of abuse readily available, and further risks are posed by counterfeit medication. Urgent national and international action is required to stop further proliferation of illegal pharmacies.

Substance misuse teaching in undergraduate medical education

BackgroundOver 12,000 hospital admissions in the UK result from substance misuse, therefore issues surrounding this need to be addressed early on in a doctor’s training to facilitate their interaction with this client group. Currently, undergraduate medical education includes teaching substance misuse issues, yet how this is formally integrated into the curriculum remains unclear.MethodsSemi-structured interviews with 17 key members of staff responsible for the whole or part of the undergraduate medical curriculum were conducted to identify the methods used to teach substance misuse. Using a previously devised toolkit, 19 curriculum co-ordinators then mapped the actual teaching sessions that addressed substance misuse learning objectives.ResultsSubstance misuse teaching was delivered primarily in psychiatry modules but learning objectives were also found in other areas such as primary care placements and problem-based learning. On average, 53 teaching sessions per medical school focused on bio-psycho-social models of addiction whereas only 23 sessions per medical school focused on professionalism, fitness to practice and students’ own health in relation to substance misuse. Many sessions addressed specific learning objectives relating to the clinical features of substance dependence whereas few focused on iatrogenic addiction.ConclusionsSubstance misuse teaching is now inter-disciplinary and the frequent focus on clinical, psychological and social effects of substance misuse emphasises the bio-psycho-social approach underlying clinical practice. Some areas however are not frequently taught in the formal curriculum and these need to be addressed in future changes to medical education.
