CALLOUS hospital workers have stolen thousands of doses of medication intended as pain relief for cancer patients, car-crash victims with spinal injuries and the seriously ill at Victorian hospitals. Herald Sun April 7 2011 Exclusive figures - released under Freedom of Information laws - show highly addictive street drugs and deadly chemicals have mysteriously vanished in 101 incidents in the past three years - and the number is rising. The Sunday Herald Sun has been told that drug-stealing workers were the cause of most of the missing medications. Insiders said nurses - particularly casually employed agency staff - were often involved in the stings. They said staff were typically stealing for personal use, but the large number of doses stolen in the thousands has raised concerns inside some hospitals that drugs are being sold on the street. The addicts' banquet of morphine, "hillbilly heroin" oxycodone, speed-like stimulant methylphenidate, the hallucinogenic horse tranquilliser ketamine, and the deadly chemical fentanyl have been smuggled out of drug safes or misplaced.

Accidental throw-outs and other human errors also resulted in losses, medical sources said. Victoria Police, who have launched investigations into at least 64 security breaches involving missing hospital drugs, say they are concerned about the booty falling into the wrong hands. The stings and bungles have plagued some of the state's most prestigious hospitals including Cabrini, the Epworth, St Vincent's Private, the Alfred and Ballarat Base. Austin Health director of pharmacy, Kent Garrett, said staff members had been sacked over eight instances of theft at the hospital over the past three years. Health Minister David Davis said the high number of thefts was a concern. "I'm looking at rigorous polices to reduce the instances of stolen medications," he said. AMA Victoria president Dr Harry Hemley said the community was put at risk when highly addictive drugs were let loose. "In the wrong hands, these substances could be dangerous and lead to drug overdoses with tragic outcomes," Dr Hemley said. Drug and addiction experts said prescription medications fetched big money once sold on the street. They were becoming the drug of choice ahead of heroin because of the price, availability and the reassurance that each "hit" was measured. Turning Point Drug and Alcohol's clinical services head, Matthew Frei said the misuse of prescription opioids in Australia was a "significant problem".
