[Burden on family caregivers of frail elderly persons one year after the introduction of public long-term care insurance service in the Onga District, Fukuoka Prefecture: evaluation with a Japanese version of the Zarit caregiver burden interview]

Factors influencing caregivers' burden among family caregivers and institutionalization of in-home elderly people cared for by family caregivers

OBJECTIVES

The purpose of this study was to determine the factors related to changes in the burden of caregivers who look after the elderly at home, as well as factors related to the institutionalization of the elderly who require care. The types of care services associated with reducing caregivers' burden and continuing in-home care were also studied.

METHODS

The study subjects were adults aged ≥65 years who used the services of in-home care management centres located in Osaka Prefecture, Japan, and their caregivers. This 2-year longitudinal study began in October 2007, with a total of three surveys undertaken once a year. The survey methods included self-administered questionnaires and the review of clinical records.

RESULTS

Dementia and its accompanying behavioural disturbances were found to be significantly related to the increased burden of caregivers and the institutionalization of those requiring care. A significantly higher proportion of caregivers with an increasing burden or those who maintained a high level of burden used day care services compared to those in the other groups.

CONCLUSION

Preventive intervention against dementia and its accompanying behavioural disturbances should be considered in the day care service to reduce caregivers' burden and to decrease institutionalization.
