The largest long-term study of paracetamol poisoning outcomes offers four critical clinical insights. First, 85% of cases are intentional overdoses, predominantly affecting young women aged 15-24 years, indicating a mental health crisis rather than accidental poisoning. Second, nearly one in four patients attempt repeat poisoning within five years, demonstrating the chronic nature of underlying self-harm behaviors.
Third, mortality risk remains elevated for the full 15-year follow-up period, even when acute liver injury is averted. Fourth, current hospital discharge protocols focus on toxicological management and miss opportunities for psychiatric intervention.
These findings have immediate clinical implications: paracetamol poisoning admissions require mandatory mental health assessment, crisis counseling before discharge, and coordinated long-term psychiatric care. Hospitals must recognize that preventing severe liver injury represents only partial success; preventing repeat attempts and long-term mortality demands integrated mental health services.
