Effectiveness of and challenges faced by surveillance systems

How to improve the surveillance of the Taliban ban's impact on European drug markets

In April 2023, the Taliban banned poppy cultivation and the trade of all narcotics. This caused a 95% reduction in opium production. Usually, that would be good news. But there is a substantial worry: synthetic opioids might fill the void left by heroin. This is concerning because these drugs have led to health emergencies in areas where they are prevalent. This paper highlights the limitations of the current drug surveillance system in Europe and proposes improvements. It argues that reliance on secondary data is insufficient. Instead, we need to interview a sentinel group of people who inject drugs and adjust city-level sentinel systems, such as wastewater analysis, to specifically track the spread of synthetic opioids. Without these proactive steps, we risk only noticing a transition from heroin to synthetic opioids after it has occurred, with its harmful impacts already in place.

Early Identification of Locally Emerging Trends in Psychoactive Substance Use - Experience and Best Practice in Four European Localities

Background: Timely information about trends in psychoactive substance use could yield tailored interventions and reduce potential harms. However, conventional epidemiological tools might have limited capacity to detect trends emerging on a local level. Objectives: The aim of this study was to explore best practice in the identification of new drug trends at the local level. Methods: A total of 33 key informants from seven European municipalities/regions were interviewed to describe trends in substance use in their locality and to provide expert insights on how these were identified. Semi-structured interviews were analyzed with open coding method. Results: Four case studies that described local trends and responses were compiled: onset of problematic GHB use in the Dutch municipality of Breda (1); emerging retail shops selling new psychoactive substances (NPS) across the regions of Czech Republic (2) and in the Portuguese Agueda and Coimbra (3); and use of drugs with unknown content in the Italian region of Emilia Romagna, and its city Bologna (4). "Early identifiers" in the four case studies were organizations that work directly with people who use drugs (PWUD), emergency departments, and local police. Efficient methods of horizontal and vertical information sharing, sometimes facilitated by communication platforms, were in place, such that included early warning systems on local, national, and supra-local level. Local-level identification systems appeared as best suited to provide locally relevant information. Conclusions: Best practice in identifying emerging trends should involve all relevant "early identifiers", should consist of supra-local exchange platforms, integrate the qualities of local-level identification, and be facilitated by local-level coordinators.

Exploring the use of drug trend data in the regional alcohol and other drug workforce

OBJECTIVE

Drug trend data can inform appropriate policies to minimise drug-related harm, as well as assist in early detection and prevention. While Australia has a number of monitoring systems, none operate in regional areas. The aim of this study was to explore how drug trend and other data are used by the regional alcohol and other drug workforce.

METHOD

Twenty-one key experts from regional Queensland were interviewed between November 2014 and August 2015. Key experts worked in or had contact with the broader alcohol and other drugs field in the Darling Downs area of Queensland. Interviews were analysed thematically.

SETTING

Darling Downs, Queensland.

RESULTS

Two themes emerged from the analysis. There were differences in workforce needs, with those in the law and criminal justice areas believing they had access to good, current data. Those in the health sector differed, although the majority indicated that there did appear to be a knowledge gap related to their location in a regional area.

CONCLUSIONS

Trends in the use of, and harms related to, substance use are well captured in urban areas, but less so in regional areas. This inhibits both our understanding of where substance use is changing, as well as how to best plan and respond.
