Determinants of overburdening among informal carers: a systematic review.

The most important predictors of caregiver burden are the duration of caregiving and the patient's dependency level. In addition, the patient's behavioural problems and cognitive capacity determine dependency level, and thus care burden. Interventions to relieve burden need to be adapted to the illness trajectory of specific diseases and corresponding needs for social support for both the recipient and the caregiver. Changing role expectations, leading to men being more involved, could reduce the disproportionately high burden for women.
