Coroners Court of Queensland - Investigation into the death of SJM
Man prescribed ongoing narcotic pain relief by doctor despite history of alcohol and substance abuse, dies from drug toxicity.
Investigation into the death of SJM
Coroner: James McDougall
Date of Death: 8 July 2012
Issues for Consideration:
- Inappropriate prescribing practices.
SJM, aged 57, had a history of alcohol and substance abuse, type 2 diabetes, gout, insomnia, anxiety and depression. His general practitioner of thirteen years, Dr JB, had a history of treating SJM for these conditions using a combination of prescription medication, including narcotics. Dr JB had a documented history of concerns regarding SJM’s substance abuse. They were also personal friends.
On the morning of 8 July 2012, SJM, aged 57, became drowsy and confused, and began to slur his words. He went back to bed, and his wife checked on him intermittently. By midday, his wife discovered that he was not breathing, and called the Queensland Ambulance Service (‘QAS’) before commencing resuscitation.
SJM was unable to be revived, and was declared deceased at 1230 hours.
Evidence of the Parties
Evidence of Dr JB, general practitioner
- SJM had been prescribed Doloxene because it controlled his back pain, he was familiar with the medication, non-steroidal anti-inflammatory medications were ineffective in controlling his symptoms, and the other options tried had side effects and may have irritated his liver.
- SJM had given up regular drinking “a long time ago”.
- SJM was usually prescribed the equivalent of 180 tablets per month, with two repeats to minimize excessive use. Medication dependency was discussed during each consultation.
Evidence of the Clinical Forensic Medical Unit
- It appears that Dr JB was aware that SJM was prone to dependency and abuse with prescribed medications and that he had abused alcohol in the past.
- Doloxene has a maximum dosage of 600mg (6 tablets) per day. It has a long half-life, making it dangerous for chronic use as it increases the risk of a toxic reaction, even at the recommended dosage. It is associated with abuse.
- Dr JB prescribed SJM with Temazepam for over 13 years. Even at the recommended dose, the use of such drugs can lead to physical and psychological dependence.
- Doloxene is also contraindicated for patients who are prone to dependency or use of alcohol in excess.
- On 6 occasions during 2010, Dr JB prescribed SJM Doloxene and/or Temazepam without a consultation, within days of a documented consultation where a prescription had already been issued for these drugs. This occurred on 7 occasions during 2011.
- Upon review of Dr JB’s clinical records, there was no evidence that SJM had been recommended any additional therapies or alternatives for his pain, such as physiotherapy.
- No prescriptions for Doloxene, Temazepam, Alprazolam or Zolpidem were recorded in SJM’s PBS Patient Summary, indicating that these prescriptions were by way of private prescription.
- Dr JB’s continued prescription of Doloxene to SLM, without further investigation into the cause of his symptoms and in the context of his medical history (namely, his alcohol and substance addiction), was unreasonable in the circumstances.
- An inquest was not warranted – it is unlikely to prevent deaths occurring in similar circumstances.
- Dr JB’s behavior was referred to the Office of the Health Ombudsman for their assessment and potential disciplinary action.
