Transforming clinical toxicology in Singapore: four decades of progress and beyond

By examining key milestones, challenges and future directions, this review chronicles the evolution of clinical toxicology in Singapore into a recognised subspeciality and thriving community of practice. Poisoning trends have transitioned alongside socioeconomic changes from agricultural toxins to pharmaceuticals, substance misuse and prescription drugs. Currently, toxicology services have expanded across public hospitals, offering 24/7 consultations and managing selected cases in short-stay observation units to optimise resources. Singapore's hazardous material (HazMat) preparedness includes specialised HazMat Medical Life Support training, antidote and personal protective equipment (PPE) stockpiling, and deployment of semi-automated decontamination facilities. Research has focused on case reports and description of local poisoning epidemiology. Toxicology has also been integrated into nursing, undergraduate medical and residency curricula, with a national fellowship programme in the pipeline. Challenges include the latent HazMat threat, rising burden of poisoning cases, continual evolution of synthetic drugs and occupational hazards from emerging industries. Future directions should emphasise interdisciplinary collaboration, regional partnerships and leveraging artificial intelligence and toxicogenomics to enhance care.
