Leveraging Health Informatics for Substance Abuse Surveillance: A Comparative Analysis of International Registry Technologies

Substance abuse poisoning remains a critical global public health challenge, necessitating robust surveillance systems to inform prevention and treatment strategies. This systematic review evaluates the design, implementation, and outcomes of substance abuse poisoning registries worldwide, with a focus on their health informatics infrastructure and technological innovations. We analyzed 8 studies and institutional reports, identifying 8 major registry systems across 6 countries (Canada, USA, Mexico, Norway, Germany, Malaysia). Key findings reveal substantial variability in registry architectures, from Canada's comprehensive Drug and Alcohol Treatment Information System (DATIS) to Malaysia's GIS-based hot-spot mapping. Technological approaches ranged from web-based platforms (Norway's Java/MySQL system) to real-time SMS alerts (Germany's poison center network). Registries demonstrated measurable impacts, including improved treatment tracking (DATIS), enhanced spatial analysis of abuse patterns (Malaysia), and faster emergency response (Germany). However, critical gaps persist, particularly in data interoperability and integration with mental health records. The review highlights how informatics solutions – including standardized data models, geospatial technologies, and mobile health applications – can address surveillance challenges in low-resource settings. For countries lacking robust systems (e.g., Iran), we propose a hybrid framework combining Canada's clinical data standards, Malaysia's GIS capabilities, and Germany's notification protocols. These findings underscore the transformative potential of health informatics in substance abuse surveillance while identifying key priorities for future research, including AI-powered predictive modeling and blockchain-based data sharing.
