Regular use of antipsychotic and antidepressant medication has increased among residents of Sydney nursing homes since 2003, an expert says.
In a letter published in the latest Medical Journal of Australia, Clinical Professor John Snowdon and co-authors also reported that regular use of anxiolytic and hypnotic medication has decreased since the 1990s. They compared their 2009 study into psychotropic medication use in Sydney nursing homes with similar studies conducted in 1993, 1998 and 2003.

By 2009, the rate of regular use of antipsychotic medication had risen above the level it had been in 1993.
In 2009, 25.6 per cent of residents were regularly taking an antidepressant compared with 15.6 per cent in 1993, while the proportion of residents prescribed anxiolytic (4.7 per cent) or hypnotic medication (11.1 per cent) regularly had fallen.
Prof Snowdon said that over time, revision of management guidelines, warnings about potentially lethal side effects, and introduction of new drugs have contributed to changes in the pattern of use of psychotropic medication in aged care facilities.
However, Prof Snowdon noted that the findings could not be generalised as recent evidence from Tasmania showed that 42 per cent of residents were taking benzodiazepines regularly.
"Nevertheless, changes in medication use should provoke discussion," Prof Snowdon said.
