“…Six methods were selected for further examination on the basis that at least two countries had either used the method or could do so within the project. 3 The six methods were (1) the multiple indicator (MI) method, (2) extrapolation from police data, (3) extrapolation from treatment data, (4) extrapolation from drug-related deaths, (5) back-calculation from HIV cases and (6) capture-recapture. The principal method to be excluded was the household population survey.…”

“…The rationale for the multiplier was based on the Home Of ce Addicts Index (AI) using a multiplier derived in the early 1980s 4 and is not likely to be applicable now, or transferable to the Regional Drug Misuse Databases which replaced the AI in 1997. 5 Other estimates based on population surveys are presented in method 3 of the next section.…”

A comparison of different methods for estimating the prevalence of problematic drug misuse in Great Britain

Aims. The European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) has produced methodological guidelines for national drug prevalence estimation. This paper pilots the methods to estimate prevalence for Great Britain and provides a commentary on the methods and resulting estimates. Design. Three types of methodology were used to estimate prevalence: (a) the multiple indicator (MI) method, (b) multipliers applied to (i) drug-treatment records (ii) HIV estimates and (iii) mortality statistics and (c) the British/Scottish Crime Surveys. Setting. England, Scotland and Wales. Participants. Aggregated data on people recorded on databases and respondents in household surveys. Measurements. Prevalence estimates of different forms of problematic drug use. Findings. The estimates are 161 133 (range: 120 850-241 700) for people at risk of mortality due to drug overdose; 161 000-169 000 for people who have ever injected drugs; 202 000 (range: 162 000-244 000) problem opiate users and 268 000 problem drug users (all types). Conclusions. The multiple indicator method offers a comprehensive approach to estimating the prevalence of problematic drug use in the United Kingdom. Simple multiplier methods and household surveys also provide a range of estimates corresponding to different types of drug use in the United Kingdom. The current study suggests that previous national estimates of 100 000-200 000 were conservative. The new estimate of 161 000-266 000 should enable a more focused response. For further development of this method, reliable and timely estimates of anchor points are required for speci c geographical areas such as cities or Drug Action Teams (DAT), as well as routine aggregation of drug indicators for these areas.

“…6 One important reason is that the GPRD was unaffected by the end of statutory notification of drug dependence in 1997. 7 We also conducted a validation study in a random sample of patients treated for substance misuse in secondary care settings. Some 92% of these cases were known to have a diagnosis of substance misuse by their general practitioner.…”

Study objective: To estimate the annual period prevalence of co-occurring psychiatric illness and substance misuse among patients in primary care. Design: Analysis of the general practice research database. Setting: England and Wales, 1993-1998. Participants: Registered patients at 230 general practices representing 3.1% of the population. A comorbid case was defined as one with both a psychiatric diagnosis and substance misuse diagnosis (not including alcohol or tobacco) within a calendar year. A potentially chronic comorbid case was one that met this definition and, in addition, was treated in subsequent years for either a psychiatric condition or substance misuse. Main results: The annual period prevalence of comorbidity increased from 50/100 000 patient years of exposure (PYE) to 80/100 000 PYE, an increase of 62% during the study period. Rates of comorbid psychoses, comorbid schizophrenia, and comorbid paranoia increased by 147%, 128%, and 144%. The average age of comorbid cases decreased from 38 years to 34 years. Over 80% of comorbid cases were newly diagnosed in each study year, although many are treated in subsequent years for either psychiatric illness or substance misuse.Conclusions: This study provides data on the nature and extent of comorbidity in primary care in England and Wales. As the comorbidity rate is increasing by about 10% each year, and as comorbid cases are becoming younger, it is probable that the comorbidity rate will have increased beyond the study end point.

“…In particular, we estimate a joint model covering past and current drug use together with unemployment and occupational success. In order to consider the life-time perspective our model is estimated separately for a younger cohort (aged [16][17][18][19][20][21][22][23][24][25][26][27][28][29] and an older cohort (aged 30-59). Before developing our empirical model, we …rst discuss the BCS data set, and its advantages and shortcomings.…”

This study, using data from the British Crime Survey (BCS), examines the e¤ect of drug use on occupational achievement. We start by attempting to overcome the identi…cation problem that results from the limited set of drug use questions presented in the BCS. Taking this into account, and allowing for the endogeneity of drug use in equations for unemployment and labour market outcomes, we observe quite different relationships for "soft" and "hard" drug use. For soft drugs, there is a positive association with occupational achievement that diminishes with age. This relationship also holds for males but not for females. In contrast, we also …nd that past use of hard drugs signi…-cantly increases the likelihood of current unemployment, although it appears to be unrelated to occupational success, conditional on achieving employment.
