NightCAP: Reducing Hypnotic Drug Use and Improving Night-time Care

Study Overview
=================
Brief Summary
-----------------
Dementia is a devastating condition characterised by progressive loss of cognition leading to loss of independence and eventually death. One major unmet need, which remains a critical challenge for care provision, is the management of night-time care and sleep-related symptoms in people with dementia living in care homes. The causes and impacts of sleep disturbances in people with dementia in care homes are complex and multi-faceted, indicating the need of a whole-systems approach to the issue. It will require a tailored, person-centred approach which accounts for the environmental, personal and clinical factors contributing to the symptoms. The aim of this study is to evaluate the NightCAP intervention to improve treatment of sleep disturbance in people with dementia in care homes, with the goal of reducing sleep disturbance behaviour and reducing the use of hypnotic drugs. This will provide robust evidence to support guidance on night time care and improving hypnotic drug prescribing, both of which are major unmet needs in the care of people with dementia.

Detailed Description
-----------------
The main objective of this current study is to explore the effectiveness of specific benefits of key components of the Night Time Care Activities Programme- NightCAP. Particularly elements of sleep hygiene and personalised night-time care planning. There may also be additional benefit in combining NightCAP elements with pharmacological review protocol to enable management of all major contributing factors in sleep disturbance. This cluster-randomised trial will be delivered in 24 UK care homes. Participants will be individuals living with dementia and experiencing sleep disturbance, as well as staff who care for them. Homes will be randomly allocated to one of two arms: optimised usual care or the intervention arm. All homes will receive an optimised person-centred care module. The NightCAP intervention programme consists of three key elements: (i) personalised night-time care planning (supported staff training and implementation); (ii) structured sleep hygiene (staff training); and (iii) hypnotic drug review protocol (GP fact sheet and staff training). The primary outcome will be sleep disturbance at the end of the intervention. Secondary outcomes will be hypnotic drug use, quality of life, resident falls, job satisfaction, burden and coping in care staff, and cost effectiveness.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sleep Disturbance Inventory SDI | Sleep disturbance behaviour as measured by the Sleep Disturbance Inventory SDI | From baseline and immediately after intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change of Hypnotic Drug Use | Hypnotic drug use assessed from the care home Medication Administration Record | From baseline, immediately after intervention and at four months follow-up | 
| Dementia Quality of Life | Quality of life assessed using DEMQOL-Caregiver. Consisting of 32 questions the DEMQOL-Caregiver is an interviewer administered measure, with higher scores indicating better quality of life. | From baseline, immediately after intervention and at four months follow-up | 
| Neuropsychiatric Inventory- Nursing Home (NPI-NH) | The NPI is a validated structured interview assessment with the informant (care staff), that assesses behavioural disturbances in patients with dementia. This 12-item version consists of 10 behavioural and two neurovegetative areas. It provides both a total score as well as scores for a number of sub-scales (e.g. delusions, hallucinations, agitation/aggression, depression/dysphoria, anxiety, disinhibition, elation/euphoria, apathy/indifference, irritability/lability, aberrant motor activity, sleep, and appetite/eating disorders). The frequency, severity and caregiver distress for each domain are measured. The total possible maximum score is 144. A higher score reflects increased frequency and severity of the disturbances. This specific version is developed for use in care homes, with adapted questions in the standardised interview and the caregiver distress assessment adapted to occupation disruptiveness. | From baseline, immediately after intervention and at four months follow-up | 
| Cohen-Mansfield Agitation Inventory (CMAI) | The CMAI is a caregivers' rating questionnaire to specify agitated behaviour (Cohen-Mansfield et al, 1980). The CMAI consist of 29 items related to agitated behaviour, each of which is rated on a 7- point scale of frequency, from 1= never to 7= several times an hour. The rating is based on a face-to-face interview with a caregiver. | From baseline, immediately after intervention and at four months follow-up | 
| Global Deterioration Scale (GDS) | The GDS is a staging scale indicating deterioration in dementia. The scale details clinical descriptions of seven major distinguishable stages, ranging from normal cognition to severe dementia. Stages 1-3 are the pre dementia stages/ Stages 4-7 reflect the stages of dementia. | From baseline, immediately after intervention and at four months follow-up | 
| Client Service Receipt Inventory (CSRI) | The CSRI is used to estimate the cost of service packages for each participant in the study. Information is collected on the current living arrangements, use of hospital, community-based and day services. The data collected through the CSRI can be used to calculate service costs and total costs of care. | From baseline, immediately after intervention and at four months follow-up | 
| Functional Assessment Staging (FAST) | FAST is a proxy-rated instrument validated for use in people with dementia. It ascertains the severity of dementia in seven stages of functioning. | From baseline, immediately after intervention and at four months follow-up | 
| EQ5D-5L | The EQ5D-5L is a measure of Health Related Quality of Life. The EQ5D-5L consist of the EQ5D descriptive system and the EQ visual analogue scale (EQ VAS). | From baseline, immediately after intervention and at four months follow-up | 
| Abbey Pain Scale | The Abbey Scale is an observation brief indicator of pain for people with end-stage dementia. The scale is rated on six non verbal indicators of pain where 0 is none and 3 is severe | From baseline, immediately after intervention and at four months follow-up | 
| Approached to Dementia Questionnaire (ADQ) | The ADQ is a 19-item instrument. Responses are indicated using a 5-point Likert scale. Higher values represent a better outcome (range from 19-96). The ADQ includes two subscales: person-centredness and hopefulness. | From baseline, immediately after intervention and at four months follow-up | 
| Patient Health Questionnaire 9 (PHQ-9) | A measure of carer mental health and behaviour consisting of 9 questions | From baseline, immediately after intervention and at four months follow-up |
