the comprehensive care and subacute care groups reported better HRQoL in physical-related function (physical functioning, role disability due to physical health problems and physical component summary score ) than the usual care group. The comprehensive care group also had better general health perceptions and better general mental health at the end of the first year than the usual care group. At the same time, the subacute care group had better health outcomes (including vitality (energy/fatigue and social functioning) relating to both physical and mental health than the usual care group. However, no dimensions of HRQoL differed significantly between the comprehensive care and subacute care groups at 12 months following discharge. Therefore, we can only conclude that both the comprehensive care and subacute care interventions more effectively improved HRQoL than usual care. These results partially support the first hypothesis and support the second hypothesis, i.e. the comprehensive care group would have better general mental health than the subacute and usual care groups.
These results mostly support the third hypothesis that the intervention effects would increase after 6 months following hip fracture. For most dimensions of HRQoL, the intervention effects for both the comprehensive and subacute care groups increased over time, specifically after 6 months following hip fracture, and reached a maximum at 12 months following discharg
