[Vulnerability of caregivers for demented patients. The Pixel study]

Caregivers of demented outpatients can have a weak health, are often old and alone, and the burden of care can generate precariousness.

This survey tends to determine the parameters influencing the caregiver's Quality of Life (QoL) and precariousness, and to measure their consequences.

A scale measuring caregivers' QoL and a scale measuring precariousness, developed from data of previous PIXEL studies were used. Each scale is a 20-item questionnaire. The results were related to the socio-demographic data of both patients and their principal caregivers, and to the patients' medical and therapeutic data.

1.410 patients diagnosed with dementia who lived at home with their principal caregivers were included in this survey. The caregivers' QoL was correlated to the carers' precariousness. Females caregivers had poorer QoL and more precariousness than men. Caregivers' QoL and precariousness were favourably influenced by specific dementia treatment. Frail caregivers had a poor QoL and an important precariousness. They were often sick and had to deal with nutritional difficulties with the demented patient. They were less satisfied with their care ability and their relationships with their patients.

Caregivers' QoL and precariousness are related and both express their distress. The specific treatment of dementia is beneficial for both of them. Presumably, this benefit would be increased by supportive care of carer and patient.
