Abstract

Introduction:

It is well established that there is a high prescribing rate of psychotropic agents in residential aged care (RAC). The appropriateness of these medications has become controversial, given the limited data on efficacy and growing evidence of associated adverse outcomes.

Objective:

To assess psychotropic prescribing in RAC including identification of potentially inappropriate prescriptions (PIPs) and common psychological and behavioral symptoms indicated for prescribing. These were viewed in context of dementia and different RAC facilities.

Methods:

Electronic care plans of 779 RAC residents across 12 facilities were examined to elucidate psychotropic prescribing rates, PIPs, and indications for use.

Results:

One in two residents (48.1%) were prescribed a psychotropic drug. The primary reasons for prescribing were depression (61.5%), anxiety (26.7%), sleep problems (25.4%), agitation (13.7%), psychosis (11.0%), and other behaviors (7.2%). Residents with dementia (56.6%) were more likely to be prescribed a drug for agitation and psychosis, and had a significantly increased prescription rate for antidepressants (OR = 1.50, 95% CI = 1.08–2.08, p = 0.01) and antipsychotics (OR = 1.88, 95% CI = 1.23–2.88, p < 0.01). Conversely, residents with dementia were less likely to receive medication to combat sleeping difficulties, with significantly lower benzodiazepine prescribing (OR = 0.63, 95% CI = 0.44–0.91, p = 0.01). Over half of all psychotropic prescriptions (54.0%) were potentially inappropriate based on the Beers Criteria. There was high variability of prescribing rates between homes.

Conclusion:

There is a high prescribing rate of potentially inappropriate medications. Residents with dementia are more likely to receive medication for agitation and psychosis, and are less likely to receive medication to combat sleeping difficulties.
