AI-generated summary

A 73-year-old man with mild dementia resident in aged care wandered from the facility on a hot day (31°C+) while taking three medications with anticholinergic properties: pericyazine, haloperidol, and oxybutynin. These drugs impair sweating and increase heat stroke susceptibility, particularly when combined. He was found deceased from dehydration and hyperthermia after exposure overnight. The coroner emphasised that while the medications were appropriately prescribed individually, staff managing elderly patients on anticholinergic drugs during hot weather should implement enhanced precautions: keeping residents indoors, maintaining cool environments, and encouraging fluid intake. The case highlights the critical interaction between medication properties, environmental conditions, and aged care supervision.

Contributing factors

  • wandering from aged care facility
  • exposure to high environmental temperature (31.3°C minimum)
  • combination of anticholinergic medications impairing thermoregulation
  • impaired ability to perspire due to drug effects
  • elderly patient with dementia
  • inadequate supervision during hot weather period

Coroner's recommendations

  1. A public warning should be issued to medical practitioners, nursing homes, and anyone concerned with the care of the elderly that where an elderly person is taking one or more medications with anticholinergic properties which reduce the ability of the body to perspire, special care should be taken during periods of hot weather to ensure such people are kept indoors as much as possible, kept cool, and are encouraged to keep their fluid levels up
