ARQ part II data management Training pack 1: Content and conceptual issues
Content Prevalence of drug abuse among the general population Prevalence of drug abuse among the school (youth) population Injecting drug abuse Severe drug abuse New developments in prevalence and patterns of drug use Drug-related morbidity Drug-related mortality Drug treatment Data collection capacity Reports and additional information
Structure Specification by drug Summary expert opinions Quantitative estimates
Specification by drug (1) What information is required? –Narcotic drugs and psychotropic substances listed in the UN conventions –Drug classes and/or drug types relevant for each question are pre-coded –Countries can add other classes and types of substance –Some questions allow aggregate information for “any drug”
Specification by drug (2) Why specify by drug? –Individual drugs show different patterns of use and risk behaviour –Individual drugs are used by different subgroups –Individual drugs have different health and social consequences
Specification by drug (3) How to obtain the information required: –Make sure that all your experts and data collectors know the ARQ terminology and classification of drugs –If reports do not specify ARQ categories, their source material might still be useful: check and ask for dedicated runs on source data –If you cannot match the ARQ categories, add and specify your own
Summary expert opinions (1) Expert opinions should be gathered on: –The occurrence of individual drugs –The rank order of individual drugs – New developments –Trends in the use of individual drugs
Example: occurrence questions NO/YES per drug NO/YES per drug + “Any drug” NO/YES per infection NO/YES per drug +“Any drug” NO/YES per drug + “Any drug”
Example: rank order questions Rank in numerical order
Example: new developments Respond according to evidence in reports or the field experience of informed experts
Example: trend questions Mark according to the perspective of your country
Summary expert opinions (2) Why include expert opinions? –Because quantitative estimates are not available or not possible –Because existing quantitative estimates might not be specific for individual drugs –To include rare and new drugs –To qualify trends in relation to context
Example: rare and new drugs –Rare drugs might not show up in survey results –Rare drugs might not be specified separately in treatment or mortality data –New drugs might not yet have been included in forms or questionnaires
Example: qualification of trends –The qualification of any absolute change as “large” or “small” depends on the starting position or the size of the reference population –An identical absolute change may be perceived as “large” for one drug but as “no great change” for another
Summary expert opinions (3) How to respond on the basis of expert opinions: –Select relevant experts: Start with existing advisory group(s) if possible Use the nomination method and purposive selection –Consult the experts: Use the expert-survey or Delphi method –Respond to the ARQ according to consensus or (weighted) average opinion
Example: assessment of expert opinions
Example: selection of experts Start with the usual government advisers or advisory group Ask them to nominate experts in different fields relevant for responding to the ARQ Select on the basis of consensus and acknowledged expertise
Example: Delphi- method consultation
Quantitative estimates (1) The ARQ asks for quantitative estimates on: –Lifetime and last year prevalence among adult and school (youth) population –Recent injecting and equipment “sharing” –“Problem” drug use –Drug-related infections –Drug-related deaths –Drug treatment
Quantitative estimates (2) Why choose these topics and report formats? –Globally accepted core indicators for the description of: The extent of drug abuse prevalence, problem use Risk behaviour in drug abuse injecting, sharing The consequences of drug abuse infections, death, treatment demand
Example: coherence between indicators
Quantitative estimates (3) Reports should consist of one of the following: –Existing data and research at national level relating to the ARQ reporting year –Purposive national estimates –Existing incomplete, fragmented, sub- national quantitative data and research reports
Example: existing data –Reports from national monitoring system –National reports to other international organizations (WHO, EMCDDA, etc.) –Results from national studies –National statistics If not related to reporting year: Attempt trend extrapolation Report most recent year available
Example: purposive estimates –Purposive for completion of the ARQ –Not applicable for all indicators –Based on accepted scientific estimation methods –Resources: Drug Abuse Rapid Situation Assessments GAP Toolkit Module 2: Estimating Prevalence
Example: fragmented data –Try to construct a national estimate by an inductive approach: Start with an expert opinion about likely national figures Check against available dispersed qualitative and quantitative information Adapt expert opinion according to findings Seek consensus among informed experts –If not possible, report a partial estimate
Data collection capacity Rate your country’s capacity to meet ARQ reporting needs Responses enable UNODC to assess needs in capacity-building
