Improving mental health and reducing antipsychotic use in people with dementia in care homes: the WHELD research programme including two RCTs

Background

The effective management of agitation and other neuropsychiatric and behavioural symptoms in people with dementia is a major challenge, particularly in care home settings, where dementia severity is higher and there is limited training and support for care staff. There is evidence for the value of staff training and the use of psychosocial approaches; however, no intervention currently exists that combines these elements into an intervention that is fit for purpose and effective in these settings based on evidence from a randomised controlled trial.

Objective

The objective was to develop and evaluate a complex intervention to improve well-being, reduce antipsychotic use and improve quality of life in people with dementia in care homes through person-centred care, management of agitation and non-drug approaches.

Design

This was a 5-year programme that consisted of six work packages. Work package 1 consisted of two systematic reviews of personalised psychosocial interventions for behavioural and psychological symptoms for people with dementia in care homes. Work package 2 consisted of a metasynthesis of studies examining implementation of psychosocial interventions, in addition to developing a draft Well-being and Health for people with Dementia (WHELD) programme. Work package 3 consisted of a factorial study of elements of the draft WHELD programme in 16 care homes. Work package 4 involved optimisation of the WHELD programme based on work package 3 data. Work package 5 involved a multicentre randomised controlled trial in 69 care homes, which evaluated the impact of the optimised WHELD programme on quality of life, agitation and overall neuropsychiatric symptoms in people with dementia. Work package 6 focused on dissemination of the programme.

Setting

This programme was carried out in care homes in the UK.

Participants

Participants of this programme were people with dementia living in care homes, and the health and care professionals providing treatment and care in these settings.

Results

Work package 1: reviews identified randomised controlled trials and qualitative evidence supporting the use of psychosocial approaches to manage behavioural symptoms, but highlighted a concerning lack of evidence-based training manuals in current use. Work package 2: the meta-analysis identified key issues in promoting the use of interventions in care homes. The WHELD programme was developed through adaptation of published approaches. Work package 3: the factorial trial showed that antipsychotic review alone significantly reduced antipsychotic use by 50% (odds ratio 0.17, 95% confidence interval 0.05 to 0.60). Antipsychotic review plus social interaction significantly reduced mortality (odds ratio 0.36, 95% confidence interval 0.23 to 0.57), but this group showed significantly worse outcomes in behavioural and psychological symptoms of dementia than the group receiving neither antipsychotic review nor social interaction (mean difference 7.37 symptoms, 95% confidence interval 1.53 to 13.22 symptoms). This detrimental impact was reduced when combined with social interaction (mean difference –0.44 points, 95% confidence interval –4.39 to 3.52 points), but with no significant benefits for agitation. The exercise intervention significantly improved neuropsychiatric symptoms (mean difference –3.58 symptoms, 95% confidence interval –7.08 to –0.09 symptoms) but not depression (mean difference –1.21 points, 95% confidence interval –4.35 to 1.93 points). Qualitative work with care staff provided additional insights into the acceptability and feasibility of the intervention. Work package 4: optimisation of the WHELD programme led to a final version that combined person-centred care training with social interaction and pleasant activities. The intervention was adapted for delivery through a ‘champion’ model. Work package 5: a large-scale, multicentre randomised controlled trial in 69 care homes showed significant benefit to quality of life, agitation and overall neuropsychiatric symptoms, at reduced overall cost compared with treatment as usual. The intervention conferred a statistically significant improvement in quality of life (Dementia Quality of Life Scale – Proxy z-score of 2.82, mean difference 2.54, standard error of measurement 0.88, 95% confidence interval 0.81 to 4.28, Cohen’s d effect size of 0.24; p = 0.0042). There were also statistically significant benefits in agitation (Cohen-Mansfield Agitation Inventory z-score of 2.68, mean difference –4.27, standard error of measurement 1.59, 95% confidence interval –7.39 to –1.15, Cohen’s d effect size of 0.23; p = 0.0076) and overall neuropsychiatric symptoms (Neuropsychiatric Inventory – Nursing Home version z-score of 3.52, mean difference –4.55, standard error of measurement 1.28, 95% confidence interval –7.07 to –2.02, Cohen’s d of 0.30; p < 0.001). The WHELD programme contributed to significantly lower health and social care costs than treatment as usual (cost difference –£4740, 95% confidence interval –£6129 to –£3156). Focus groups were conducted with 47 staff up to 12 months after the end of work package 5, which demonstrated sustained benefits. Work package 6: the outputs of the programme were translated into general practitioner workshops and a British Medical Journal e-learning module, an updated national best practice guideline and a portfolio of lay and care home outreach activities.

Limitations

Residents with dementia were not involved in the qualitative work.

Conclusions

The WHELD programme is effective in improving quality of life and reducing both agitation and overall neuropsychiatric symptoms in people with dementia in care homes. It provides a structured training and support intervention for care staff, with lower overall costs for resident care than treatment as usual.

Future work

It will be important to consider the long-term sustainability of the WHELD programme and cost-effective means of long-term implementation.

'Dance to Health': an evaluation of health, social and dance interest outcomes of a dance programme for the prevention of falls

Background: Falls and related injuries in the older population are major public health issues requiring more innovative and effective solutions. This paper reports an evaluation of the Dance to Health (DtH) programme which integrates evidence-based physiotherapy falls-prevention exercises into creative dance.Methods: Sixty-seven participants took part in a mixed-methods study that combined focus group discussions and six pre/post-test questionnaires with a focus on dance interest and ability, group identity, loneliness and isolation, general health and mental health.Results: The findings show that the DtH programme can support and enhance physical, mental and social health and levels of interest in dance. The mixed data yielded evidence of positive change, with statistical significance in findings relating to group bonding and improved physical control and coordination.Conclusions: The findings support the case for recommending the Dance to Health programme in falls-prevention services in relation to its ability to promote a wide range of health and wellbeing benefits.

Exploring the relationship between community-based physical activity and wellbeing in people with dementia: a qualitative study

This study sought to identify factors which influenced how a group of people with dementia living in their own homes participated in community-based physical activity and explored the effect that exercise groups, dance and walking had on their wellbeing. A broadly ethnographic approach was adopted in which participant observation and interviews were employed. Nineteen people with dementia and seven formal and informal carers were included in the participant observation phase. Eleven people with dementia were interviewed. The analysis and interpretation of data was informed by embodiment and social constructionist theoretical perspectives. Findings suggest that a complex interplay between attitudes and beliefs, retained embodied abilities, and aspects of the physical and social environment influenced how individuals engaged in physical activity and the degree to which they experienced wellbeing as a result. Findings suggest that when certain factors co-exist, physical activity can provide a context within which people with dementia are able to use embodied skills in order to support fragile identities, connect with others and express themselves.

Humor in the "Twilight Zone": My Work as a Medical Clown With Patients With Dementia

Medical clowning has been primarily identified with working with children in pediatrics wards in hospitals. Over the past decade, more and more medical clowns have been working with adults and with patients with dementia as part of holistic care. Along with traditional medical care by hospital staff, the medical clown treats the patient's emotional side. Furthermore, medical clowning has unique advantages in working with patients with dementia. Several studies have shown that humor assists in improving the quality of life of patients with dementia. The clown, as the ultimate comic figure, creates interactions with patients based on humor, which empowers, calms, and strengthens the patient while reinforcing the patient's connection with the surroundings. Medical clowning is an interdisciplinary therapeutic art, and the medical clown has a "kit" of multiple skills (including humor, drama, music, and dance), all of which have a beneficial, therapeutic impact on patients. The current article presents and analyzes case studies from my work as a medical clown with patients with dementia.

Dance in mental health nursing: a hybrid concept analysis

The aim of this concept analysis is to describe the defining attributes and consequences of the concept of dance and to define it in a mental health nursing context using hybrid concept analysis. Dance is a human resource learned from culture. Dance implies body movements, steps, expression, and interaction. The outcomes of dance are mostly functional, including a client's physical and emotional health, well-being, ability to cooperate with other people in activities of daily life, and meeting role expectations within family and community. Based on the findings of this concept analysis, dance can be used as a nursing intervention.

Emotional response to social dancing and walks in persons with dementia

The emotional response to social dancing and walks in persons with dementia was studied to better understand the feasibility, popularity, and meaning of these activities from the perspective of the patient. Social dance events and walks were videotaped and analyzed using Husserl's philosophy as a basis for the analysis. Six persons with dementia participated in the study. The results are described in terms of four interrelated themes: 1) the engaged body; 2) the caregivers' understanding, encouragement, and response to patients during the activity; 3) mutual tenderness and communion; and 4) environmental conditions. Results were then synthesized into a general assessment of the emotional states observed and reported in relation to the activities.
