Reducing Inappropriate Polypharmacy in Care Homes
I have been a qualified pharmacist for over 10 years and I am currently completing the Darzi Fellowship; a one year leadership course accredited by London South Bank University (LSBU). Within this year, I have been tasked with a project to ‘reduce inappropriate polypharmacy in south London care homes’. An exciting but daunting task for a 12-month period, which if I am successful in, has the potential to reduce hospital admissions, 5-20% of which are related to adverse drug events, and subsequently contribute to saving the NHS millions of pounds per year3 As part of this project, I also aim to specifically reduce the use of anticholinergics in people with dementia. Anticholinergic medicines, often prescribed for various conditions (such as hay-fever and depression), can cause a number of uncomfortable side-effects such as constipation, dry mouth, dry eyes and confusion, but beyond that, they also block the beneficial effects of medicines used for dementia.
Dementia generally affects the older population, for whom polypharmacy is commonplace. Taking numerous medications poses the risk of medication errors, non-adherence and adverse drug reactions and is particularly dangerous for the older population as some of these individuals may also be extremely frail leading to increased susceptibility to illness and slower recovery times. Between this, and the fact that at the current estimated rate of prevalence, the number of people with dementia in the UK is forecast to increase to over 1 million by 2025 and over 2 million by 2051, I was determined that my project would contribute to improving the quality of life of care home residents living with dementia.
My project has been focussed on four care homes in south London. At each of these care homes, we are trialling several interventions. One involves the nurses and carers being informed on the dangers of anticholinergic drugs for people living with dementia and which medications have high anticholinergic activity so they can highlight their use to the pharmacist or doctor. The aim is that the medicines will be reviewed and hopefully reduced or stopped if no longer providing the most benefit to the resident. Another intervention involves educating residents and relatives on the potential risks of polypharmacy so they will understand why some medicines might be stopped. Data is being collected around the knowledge and confidence of nurses and carers to highlight these medicines for review to the pharmacist or doctor and if the reviews result in reduced use of anticholinergics.
Working on this Darzi project is very new to me, but it has been a great way to not only use my pharmacy background to have a direct impact on improving outcomes for a vulnerable patient group, but it has taught me a lot about project management and the importance of building good relationships with all your stakeholders. I have thoroughly enjoyed meeting new people from different organisations and getting to share my knowledge with others, knowing it might help them to improve outcomes for care homes residents. Although there are no results to report yet, I have learnt a great deal.
My top tips so far, for how to reduce inappropriate polypharmacy in care homes are:
1. Involve everyone in the decision-making. Polypharmacy affects the care home residents, relatives and staff members and so ensuring that everyone’s voice is heard is imperative. Consider holding focus groups for residents/relatives and attending GP and care home meetings to capture healthcare professionals’ opinions.
2. Keep your stakeholders updated and informed. Engaging all stakeholders once and then not communicating with them again will lose their enthusiasm for the project. Attend regular meetings or send information to be added to their local newsletters so that everyone is kept informed. Also, ensure that the GPs have agreed for any interventions to be trialled.
3. Target the type of medicines you want to concentrate on reducing. There are hundreds of medicines available in the UK and so it is important to pick the specific medicines you want to work on first. Think about the medicines that may be causing the most harm in your chosen population.
I hope the data collected from this project will demonstrate that these simple but effective interventions can contribute to reducing the use of inappropriate polypharmacy in care homes, and – most importantly – improve outcomes for residents with dementia. And if so, I hope that other care homes in south London will be able to easily adopt some of the methods used in my project and perhaps even spread it across the rest of London.
There are no results to report on this yet but final results will be published on the Health Innovation Network website in August 2019.
