Unit
- Toxicology information services (TIS): A specialized discipline that collects, evaluates, and disseminates data on chemical hazards, poisonings, and adverse effects to support clinical care, public health, and regulatory decisions. TIS operates at the intersection of library science, clinical toxicology, and risk management.
- Core functions: TIS professionals perform literature searches, maintain poison center databases, develop educational materials, provide drug and poison information consultations, and assist in outbreak investigations. Each function requires distinct skill sets and knowledge bases.
- Key stakeholders: Users include emergency physicians, poison control center staff, industrial hygienists, regulatory agencies, environmental health officers, and the general public. Information must be tailored to each audience's technical level and urgency.
- Information lifecycle: Toxicology information follows a cycle: identification of need, search strategy development, data retrieval, critical appraisal, synthesis, dissemination, and outcome tracking. Errors at any stage can compromise patient safety or regulatory action.
- Regulatory context: National and international bodies such as the EPA, FDA, ATSDR, and WHO set standards for toxicological data submission and dissemination. TIS must align with legal requirements for hazard communication and product safety.
- Ethical frameworks: Confidentiality, equity in access, transparency in evidence evaluation, and conflict of interest management are guiding principles. TIS professionals often encounter sensitive exposure data that must be handled ethically.
- Relationship to clinical care: In clinical settings, TIS supports differential diagnosis, antidote selection, and management guidance. Timely, accurate information can reduce morbidity and mortality from poisonings.
- Relationship to public health: Population-level surveillance of exposures and poisonings depends on TIS for data aggregation, trend analysis, and early warning of emerging threats such as new psychoactive substances.
- Training and certification: Toxicology information specialists typically hold advanced degrees in library science, pharmacology, or public health, with optional certification through organizations like the American Association of Poison Control Centers. Continuing education in toxicology and informatics is essential to keep pace with emerging substances and new research methodologies.
- Technology and tools: Modern TIS relies on specialized databases such as TOXNET, POISINDEX, and PubMed, along with knowledge management systems and electronic health record integrations. Automation and artificial intelligence are increasingly used for rapid data extraction and triage of routine inquiries.
- Challenges and barriers: Common challenges include information overload, inconsistent data quality across sources, language barriers in international poisonings, and the need for rapid updates as new chemicals enter the market. TIS professionals must critically evaluate sources and manage uncertainty in high pressure situations.
Scope of Practice
