Evaluation of an Innovative Information, Training and Social Support Intervention "INFOSADEM" to Principal Caregivers of Dementia Patients Living at Home (INFOSA-DEM)

Evaluation of an Innovative Information, Training and Social Support Intervention "INFOSADEM" to Principal Caregivers of Dementia Patients Living at Home. Experimental Study

Background: Dementia is an illness that mostly affects people of advanced age and causes disability and dependency. Although the difficulties, a vast number of older people with dementia at our context, are cared for in their own homes by a family member, usually their spouse/partner, son, daughter or companion, but it is well known that this could be one of the main factors of institutionalization. However, home care is an effective option for the health system. This care may be provided over months or years and can have negative effects on the caregivers' health. This article describes the development and implementation of a structured, psychoeducational intervention addressed to informal caregivers of people with dementia cared for at home.

Methods: A quasi-experimental study with repeated observations at 3 and 6 months post-intervention was performed. Intentional sampling and convenience assignment method was used for intervention and control groups. The intervention was structured developed at the beginning of the study, which consists of a multicomponent training, information and emotional support programme of five, 90-minute sessions over one week. The control group received Usual Care. The project was approved by the ethics committee (HCB/2014/0317) and follows the recommendations of the Declaration of Helsinki. Evidence gathered from our research will be published at national and international level.

Discussion: The results of this intervention will support other studies and contribute scientific evidence on the importance of promoting non-pharmacologic interventions in informal caregivers of people with dementia. At the same time, they can be used as the basis for the implementation of psycho educational interventions in home care and in long-term care institutions responsible for monitoring people with dementia; responding to training and information needs, and providing the social support that the caregivers themselves demand.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: intervention group; The INFOSA-DEM programme consists of five, 90-minute informational/training sessions delivered consecutively over one week. Morning or afternoon groups are offered depending on the caregiver's availability. Programme content was developed for use in small groups of 6-8 caregivers. Topics covered in the sessions include basic concepts in dementia and specific issues such as nutrition, rest, medication, physical and cognitive changes, management of behavioural symptoms, affective problems in the patient and informal caregiver, verbal and non-verbal communication techniques, caregiver self-care and information on available resources and community services. The sessions are conducted using audio-visual material to facilitate understanding of the content and to encourage active participation among caregivers when talking about their experiences.	Other: INFOSA-DEM; Caregivers in the intervention group received the INFOSA-DEM programme, together with usual care provided by the participating centres, while caregivers in the CG received usual care in the centres where the follow-up was carried out.
No Intervention: usual care; Caregivers in the Group control received usual care in the centres where the follow-up was carried out. This consisted of annual or quarterly consultations with a health professional (GP, geriatrician or neurologist) and, depending on the health centre, a nurse and social worker.Currently, there is no homogenous protocol for all care centres for the patient with high levels of cognitive impairment and dependency.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Preparedness for Caregiving	Preparedness for Caregiving Scale (PCS; 8 items): Assess readiness for tasks and demands of caregiving role. Domains include providing physical care, providing emotional support, setting up in-home support services and deling with the stress of caregiving. Participants are asked to identified how well prepared they feel on a scale from not all prepared (0) to very well prepared (4). Cronbach's Alpha: 0.88-93	2 years
positive and negative aspects of care	. Caregiver Reaction Aspects (CRA; 24 items): consists of 24 items in five subscales: self-esteem (range 7-35), lack of family support (range 5-25), financial problems (range 3-15), disrupted schedule (range 5-25) and health problems (range 4-20).	2 years
perceived social support	Perceived Social Support Questionnaire (Duke-UNK; 8 items): Instrument to measure the strength of the person's social support network. Cronbach's Alpha: 0.88.	2 years
Level of Quality of life: EQ-5D	Quality of Life Scale (EQ-5D): a measure of self-reported quality of life that is applicable to a wide range of health conditions and treatments. It consists of two parts: a descriptive system (Part I) and a visual analogue scale (VAS) (Part II). Cronbach's Alpha: 0.87.	2 years
FAMILY NEEDS	Family needs inventory	2 years
level of burden	Zarit Burden Scale (ZBS; 22 items): a questionnaire developed to measure subjective burden among caregivers. Cronbach's Alpha: 0.92.	2 years
Neuropsychiatric Inventory (NPI)	Assess dementia-related behavioral symptoms. Is composed by 10 sub-domains: delusions, hallucinations, agitation/aggression, dysphoria, anxiety, euphoria, apathy, deshinibition, irritability/liability, and aberrant motor activity. Cronbach's Alpha:0.88	2 years
degree of independence in activities of daily living	Katz index of Activity of Daily Living (KATZ; 5 items): to assess an older adult's baseline ability to bathe, dress, use the toilet, transfer, remain continent, and feed her- or himself. It's also used for evaluating changes in response to illness. Cronbach's Alpha: 0.87	2 years
Competence for care	The Perceived Competence Scale for Care	2 years

Other Outcome Measures

Outcome Measure	Measure Description	Time Frame
level of cognitive deterioration	Global Deterioration Scale (GDS): provides caregivers an overview of the stages of cognitive function for those suffering from a primary degenerative dementia such as Alzheimer's disease. It is broken down into 7 different stages. Stages 1-3 are the pre-dementia stages. Stages 4-7 are the dementia stages. Beginning in stage 5, an individual can no longer survive without assistance.	2 years
Comorbidity	Charlson Comorbidity Index (CCI): Assess multiple comorbidity. To complete the Index, patients are asked whether they have a history of medical problems in 12 areas. Among patients with chronic medical conditions, the Index categories were predictive of 1-year mortality and health care costs. Cronbach's Alpha: 0.96.	2 years
