Potentially inappropriate prescribing among people with dementia in primary care: a retrospective cross-sectional study using the Enhanced Prescribing Database

Background: Little is known about prescribing appropriateness for community-dwelling people with dementia (PWD).
Objective To estimate potentially inappropriate prescribing (PIP) prevalence among PWD in primary care in Northern Ireland, and to investigate associations between PIP and polypharmacy, age and gender.

Methods: A retrospective cross-sectional study was conducted, using data from the Enhanced Prescribing Database. Patients were eligible if a medicine indicated for dementia management was dispensed to them during 01/01/2013 – 31/12/2013. Polypharmacy was indicated by use of ≥4 repeat medications from different drug groups. A subset of the Screening Tool of Older Persons Potentially Inappropriate Prescriptions (STOPP) criteria, comprising 36 indicators, was applied to the dataset. Overall prevalence of PIP and the prevalence per each STOPP criterion was calculated as a proportion of all eligible persons in the dataset. Logistic regression was used to investigate associations between PIP, polypharmacy, age and gender.

Results: The study population comprised 6826 patients. Polypharmacy was observed in 81.5% (n=5564) of patients. PIP prevalence during the study period was 64.4% (95% CI 63.2 – 65.5; n=4393). The most common instance of PIP was the use of anticholinergic/antimuscarinic medications (n=1718; 25.2%; 95% CI 24.2 – 26.2). In multivariable analyses, both polypharmacy and gender (being female) were associated with PIP, with odds ratios of 7.6 (95% CI 6.6 – 8.7) and 1.3 (95% CI 1.2 – 1.4) respectively. No association was observed between PIP and age, after adjustments for gender and polypharmacy.

Conclusion: This study identified a high prevalence of PIP in community-dwelling PWD. Future interventions may need to focus on certain therapeutic categories and polypharmacy.

Thermal environments and comfort in dementia friendly dwellings

This study follows on from a research project that developed guidelines for the Universal Design (UD) of Dementia Friendly Dwellings for People with Dementia, their Families and Carers. Research findings point to the need for thermal environments that support people with dementia and do not provoke stress, agitation or anxiety. Using semi-structured interviews and qualitative analysis of people with dementia this paper aims to provide insight into the questions of appropriate thermal environments. The qualitative analysis is supported by example simulated indoor environment studies that investigate comfort in common thermal environment provision scenarios in the homes of people with dementia. This paper focuses on the thermal environment, its impact on people with dementia, its therapeutic value, and its role in encouraging engagement in every day activity.
Findings from the interviews emphasize that control over their own internal environment is a priority for people with dementia. A strong preference for naturally or passively conditioned environments over mechanical conditioning is evident. Preferences are expressed for naturally ventilated environments enabling occupant instigated air movement. Repeated emphasis is placed on familiar elements including the fire and hot water bottle. Little desire is expressed for information feedback or technological displays.

Evaluation of 'Dementia Friends' programme for undergraduate nursing students: Innovative practice.

The ‘dementia friends’ programme was launched by the Alzheimer’s Society in the UK two years ago with the purpose of educating members of the public about the things they can do which can enhance the lives of people living with dementia. The aim of this project was to deliver a two-hour ‘Dementia Friendly Community Workshop’ written by the Alzheimer’s Society, to an entire cohort of first-year undergraduate nursing students in one Higher Education Institutions in Northern Ireland. Following delivery of the programme, students were asked to complete a short questionnaire on their knowledge and confidence in relation to dementia care before and after the Dementia Friendly Community programme. A total of 322 undergraduate first-year nursing students took part in the Dementia Friendly Community programme. Of these, 304 returned questionnaires; 31.25% of students stated their perceived improvement in dementia knowledge was ‘good’ while 49.01% stated their perceived improvement in dementia knowledge was ‘very good’ and 13.49% stated their perceived improvement in dementia knowledge was ‘excellent’. In relation to confidence in engaging with people with dementia, 31.91% stated ‘good’ improvement, 40.79% stated ‘very good’ improvement and 11.84% stated ‘excellent’ improvement. The Dementia Friendly Community programme was positively reviewed by the undergraduate students as it enhanced knowledge and confidence in relation to care of someone living with dementia.

Initiating advance care planning on end-of-life issues in dementia: Ambiguity among UK and Dutch physicians

Background
In dementia, advance care planning (ACP) of end-of-life issues may start as early as possible in view of the patient’s decreasing ability to participate in decision making. We aimed to assess whether practicing physicians in the Netherlands and the United Kingdom who provide most of the end-of-life care, differ in finding that ACP in dementia should start at diagnosis.

Methods
In a cross-sectional study, we surveyed 188 Dutch elderly care physicians who are on the staff of nursing homes and 133 general practitioners from Northern Ireland. We compared difference by country in the outcome (perception of ACP timing), rated on a 1–5 agreement scale. Regression analyses examined whether a country difference can be explained by contrasts in demographics, presence, exposure and role perceptions.

Results
There was wide variability in agreement with the initiation of ACP at dementia diagnosis, in particular in the UK but also in the Netherlands (60.8% agreed, 25.3% disagreed and 14.0% neither agreed, nor disagreed). Large differences in physician characteristics (Dutch physicians being more present, exposed and adopting a stronger role perception) hardly explained the modest country difference. The perception that the physician should take the initiative was independently associated with agreeing with ACP at diagnosis.

Conclusions
There is considerable ambiguity about initiating ACP in dementia at diagnosis among physicians practicing in two different European health care systems and caring for different patient populations. ACP strategies should accommodate not only variations in readiness to engage in ACP early among patient and families, but also among physicians.
