AI-generated summary
Wendy Osborne, a woman with a history of substance abuse and psychiatric issues, died from bronchopneumonia complicating fentanyl overdose. Her GP prescribed fentanyl patches (50mcg/h, increased to 75mcg/h) after one week of oxycodone for disc-related back pain. Key clinical lessons include: fentanyl should not be initiated at doses >25mcg/h in non-opioid-tolerant patients; careful monitoring is essential in patients with prior drug abuse; warnings about heat exposure must be given; and close adherence to prescribing guidelines is critical. The coroner noted Dr S.'s prescriptions were excessive and inadequately monitored given the deceased's documented medication abuse history, though concluded they fell within the permissive prescribing culture of 2010. Contributing factors included possible application of heat from a hot water bottle, potential early patch changes, and lack of monitoring despite known abuse history.

Error types
Drugs involved
Contributing factors
- inappropriate prescribing of fentanyl at excessive initial dose (50mcg/h) for non-opioid-tolerant patient
- rapid escalation from 50mcg/h to 75mcg/h within four days
- inadequate monitoring of patient with documented history of medication abuse and overdoses
- failure to provide warning about heat exposure to patches
- application of heat from hot water bottle to patch site
- possible early replacement of patches (less than 72-hour interval)
- possible application of multiple patches simultaneously
- combined sedating effect of fentanyl with other prescribed medications
Coroner's recommendations
- The Therapeutic Goods Administration consider changing the product information for fentanyl transdermal patches to ensure that it contains no potential anomalies
- Medical practitioners ensure that, in prescribing fentanyl transdermal patches, they follow closely the relevant prescribing directions
