industry & reform Reducing sedative use Exploring the RedUSe intervention in aged care. By Juanita Westbury F red was a resident with Alzheimer’s disease living at one of our aged care homes. He was a quiet man. In fact, Fred had not spoken for years. Like many people with dementia, he became agitated and upset, particularly around evening meals. He would refuse to eat at certain times. Two years ago, Fred was prescribed a small dose of risperidone, an antipsychotic, to help him settle. After review, Fred was slowly taken off his risperidone. Soon after, he mumbled something after an evening meal. The carer, absolutely astonished to hear him talk, asked him to speak up. “I hate soup … pumpkin soup.” The carer quickly rung Fred’s family to tell them he had spoken. They confirmed he hated pumpkin soup with a passion. Staff recalled that Fred became more agitated at meals where this soup, the cook’s speciality, was served. Being forced to eat food he disliked was probably contributing to his agitation. Taking a heavy sedating drug, along with his dementia, made it difficult for him to tell anyone. The home pledged to never serve Fred pumpkin soup again. We frequently heard stories like this when our intervention, RedUSe (Reducing Use of Sedatives), was delivered to 150 14 agedcareinsite.com.au aged care homes across Australia from 2014 to 2016. 1 Few were as dramatic as Fred’s, but we often heard staff say that when residents came off sedating medication they became more engaged and less confused. For many, reducing the drugs made little difference to their agitation level or other behaviours. Care staff also told us they felt a sense of achievement when they successfully managed an agitated or anxious resident without resorting to medication. It is important to acknowledge that some residents do require psychiatric medication with sedating properties (i.e. antipsychotics, benzodiazepines, sedating antidepressants) if they have mental illness such as schizophrenia, bipolar disorder, severe anxiety states and major depression. Further, some people with dementia experience very high levels of distress, hallucinations and/ or pose a risk of harm to themselves or others. Prescribing antipsychotics to these residents is justified provided their effectiveness and adverse effects are closely monitored and the lowest effective dose is taken for a time-limited period (usually three months). 2 However, when these medications are given to older people with less serious symptoms such as calling out, agitation and wandering, the risks associated with use often outweigh any benefit they may offer. To give an example, about one in five residents with dementia experiencing agitation will benefit from taking antipsychotics, yet taking these medications increases the risk of stroke, pneumonia, death from all causes, cardiac problems, falls, tremor and confusion. 2 My own qualitative research, and that of researchers overseas, has found that care staff will often request psychotropic medication from prescribers with the aim of ‘providing comfort’ or ‘to calm’ residents. 3 Most staff don’t want to ‘dope residents up’ for their own convenience. Many staff and health practitioners also have a strong belief in medication, trusting that these drugs are much more effective than the evidence suggests. When we gave staff a psychiatric drug knowledge quiz, we found that most care staff and health practitioners were unaware of their adverse effects. 4 Few could name a guideline they referred to when prescribing or administering these medications. There is also marked resistance to take residents off sedating medication for fear that behaviours will escalate. Yet, withdrawal studies suggest that most people with less severe symptoms can be taken off these medications successfully with minimal impact on behaviour. 5 What does the RedUSe intervention involve? It’s a program lasting six months involving awareness raising, education and sedative review. To raise awareness of sedative medication use, we audited each home and then compared their use to others. One large Queensland home assured me they didn’t have a problem, only to find that over a third of residents were taking antipsychotics. If you don’t measure or compare use, it’s difficult to assess if use is too high. After, the audit results are provided to staff, along with education on sedative use by trained pharmacists. These sessions aimed to promote discussion by asking if these drugs improved quality of life, provoking some very spirited debates. Finally, a structured review process was conducted where a nurse, pharmacist and GP reviewed all residents at the home taking sedatives. 1 Over the past few months, when bad news stories about aged care prevailed, we found that most aged care staff wanted to
