The Royal Adelaide Hospital has adopted an initiative that was developed at PARC Clinical Research and spearheaded by our Director Professor Guy Ludbrook. The initiative entitled "Preoperative assessment and management for adult elective surgery in South Australia". The project will focus on the development of a State-wide Model of Care for preoperative assessment and management for adult elective surgery in South Australia and a Clinical Governance Framework to deliver the Model of Care within each LHN.

A clinical pharmacologist’s journey in pain research and treatment
Paul Rolan speaks to Roshaine Gunawardana, Commissioning Editor: Paul Rolan graduated in Medicine (MBBS) from the University of Adelaide, Australia, in 1979 and trained in internal medicine and clinical pharmacology. In 1987 he went to the UK to work at the Wellcome Research Laboratories where he was responsible for the exploratory development of a range of compounds, some of which became marketed (atovaquone, zolmitriptan). He was awarded an MD degree from the University of Adelaide in 1995 for novel conceptual work on the use of biomarkers in exploratory development for work performed while at Wellcome.

What to do about opioids for chronic noncancer pain? A perspective from Australia.Many countries in the developed world are awash with opioid overuse, misuse and opioid - related deaths, which have paralleled the increasing medical use of opioids for chronic noncancer pain. This is despite growing concern over the efficacy of these drugs in long-term management. To attempt to reduce the harm associated with opioids but to ensure the continued availability for patient benefit, multiple attempts to develop guidelines, improve regulation and training have recently been attempted or are in progress.

Comparison of pain models to detect opioid-induced hyperalgesiaObjective: Chronic opioid therapy may be associated with hyperalgesia. Our objective was to determine if opioid-induced hyperalgesia detection sensitivity is dependent on the stimulus used to detect it.
Methods: This open design study compared the detection of hyperalgesia in opioid-dependent subjects (n = 16) and healthy control subjects (n = 16) using the following pain stimuli: cold pain, electrical stimulation, mechanical pressure, and ischemic pain. The opioid-dependent subjects were maintained on either methadone (n = 8) or buprenorphine (n = 8) for at least 3 months. None of the controls was dependent on opioids or other drugs of abuse.
