This carer study forms part of a wider study which compares accelerate
d rehabilitation after proximal femoral fracture with conventional car
e. Two measures of burden on family caregivers were used: social worke
r's assessment of overall burden and an index of disruption to carers'
lives. Participants were carers of 200 patients interviewed at five p
eriods up to 12 months after fracture. Carer burden prior to the fract
ure was the strongest predictor of subsequent burden, with carers of p
atients in nursing homes and patients with a cognitive or physical dis
ability being more burdened. Carer burden may increase or decrease aft
er the patient's injury, irrespective of randomization group. There is
no simple relationship between burden and randomized group. Accelerat
ed rehabilitation does not impact greatly on carer burden, but already
severely burdened carers may benefit from additional counselling/info
rmation. Specific ways in which carers' lives were disrupted are repor
ted.
