Résumé :
Aims :
The OPAAK study aimed to provide up-to-date information on the populations of people with high-risk use of opioids and crack cocaine, while also identifying emerging groups of people with high-risk drug use. The study was structured into four main goals. First, we aimed to estimate the population sizes of people with HROU and HRCCU-only and assess their drug use patterns, health, wellbeing, and integration in addiction care services. To contextualize and assist with the interpretation of the population size estimates, we evaluated the accuracy of LADIS, the national registration system of addiction care in the Netherlands. Second, we assessed the coverages of opioid agonist therapy and needle and syringe programs to evaluate access to these essential healthcare services. Third, we performed a needs assessment of people with HROU and HRCCU-only to better understand their specific challenges and needs. Fourth, we aimed to identify and characterize new emerging groups of people with high-risk drug use. With this comprehensive approach of the OPAAK study, we sought to address both established and evolving aspects of high-risk drug use in the Netherlands.
Study design:
OPAAK was an observational, cross-sectional study utilizing both quantitative and qualitative research methods. Data for the population size estimates and service coverages was collected from people with HROU and HRCCU-only by means of structured interviews, in which participants completed a questionnaire together with field workers. Participants were recruited in eight cities across the Netherlands between July 2023 and July 2024. The population size estimates were calculated using the Multiplier Method. For the needs assessment, focus groups and individual interviews were conducted with people with HROU and HRCCU-only in different cities in the Netherlands. Finally, to identify new emerging groups of people with high-risk drug use, focus groups and individual interviews were organized with a range of professionals and other experts across the Netherlands.
Study population:
The overall study population was adults (age 18 or older) self-reporting high-risk drug use. The two main target groups were people with high-risk opioid use (HROU), who may or may not also engage in high-risk crack cocaine use, and people with high-risk crack cocaine use without high-risk opioid use (HRCCU-only). Eligibility criteria were based on the case definitions of high-risk drug use of the European Union Drugs Agency. [Extract from the summary]
