Health condition(s) or problem(s) studied:
Sedative use in residential aged care facilities. Sedatives are classified for the purposes of this study as antipsychotic, anxiolytic and hypnotic drugs. The majority of anxiolytic and hypnotic dugs are benzodiazepines. 3048 0

Study type
Description of intervention(s) / exposure
1. Academic detailing – the research team will present a brief evidence-based educational session on appropriate use of sedatives to General practitioners (GPs) servicing residential aged care facilities (RACFs). This detailing will be conducted in the first three months of the project.
2. Case conferencing at residential aged care facilities. This intervention is part of the "enhanced care initiative" for GPs and involves co-ordinating a meeting between nursing staff, GP, pharmacist and resident or their relatives to discuss sedative management. It is estimated that one hundred case conferences will be conducted during the trial duration.
3. Drug Use Evaluation (DUE) - This intervention is similar to a clinical audit of prescribing, and involves individual measurement of sedative use at each RACF for presentation back to the nursing staff at the facility. Three DUE cycles will be completed; however feedback will be given to the nursing facility at baseline and at three months post-intervention.
4. Nursing home staff training - will be conducted by pharmacists and incorporate the results of the DUE and education regarding appropriate use and review of sedatives. Training is already recommended to be supplied by each community pharmacy supplying nursing homes. Two training sessions will be delivered to available nursing staff members throughout the six month duration of the trial.

Other interventions
Comparator / control treatment
drug use evaluation (DUE)- The drugs evaluated will be antipsychotics and benzodiazepines. The DUE will be collected via a computer program using a data mining technique from pharmacy drug supply records at the pharmacy. This evaluation will be completed at each of the 24 residential aged care facilities. The DUE will be used to measure the sedative usage rates at each facility. the DUE measure will be completed at baseline, 12 weeks and 26 weeks post-intervention.
Control group

Primary outcome [1] 4090 0
Prevalence rate of benzodiazepines and antipsychotics. This rate will be the percentage of residents prescibed antipsychotics in each facility, and the percentage of residents prescribed benzodiazepines in each home.

baseline, 3 months and six months
Secondary outcome [1] 6883 0
rate of dose alteration of antipsychotics and benzodiazepines

Secondary outcome [2] 6884 0
Prevalence rate of antidepressants. This rate will be the percentage of residents prescribed antidepressant treatment in the facility.

Secondary outcome [3] 6885 0
Acceptibility of intervention for participants. We will be conducting a series of focus groups to assess this measure. The first will involve consenting residents and enduring guardians/persons responsible. Another focus group will involve nursing staff, pharmacists and GPs to assess acceptibility of the set of interventions for health professionals.

Intervention assignment
Other design features
All Residential Aged Care Facilities (RACFs) in Hobart and launceston will be invited to particpate in ReDUSe. Twelve RACFs will be selected for the intervention after their supply pharmacy aggrees to participate. Control RACFs will be matched to the intervention homes after their community pharmacy agrees to participate.

Brief summary
Studies have consistently shown that the use of sedative medications in many residential aged care facilities is excessively high. These agents are associated with side effects such as falls, daytime drowsiness and confusion. The most effective interventions to reduce sedative prescribing involve all key staff in this setting, namely nurses, GPs and pharmacists.

The Australian government has recommended that pharmacists become more involved in ensuring appropriate use of sedative medications. The strategies of Drug Usage Evaluation (DUE) cycles and nursing staff training are currently promoted; however, there has been limited training for community pharmacists to effectively deliver these strategies. There are also no co-ordinated DUE and staff training packages that target sedative prescribing in residential aged care.

This project aims to develop, trial and evaluate a sustainable program [Residential care: Decreasing Use of Sedatives (‘ReDUSe’)], to address inappropriate sedative prescribing in residential aged care. The strategies that form the ReDUSe program will be co-ordinated by the community pharmacy supplying the aged care home and involve the accredited pharmacist.
