ObjectivesTo determine the contribution of cognitive impairment, prefracture functional impairment, and treatment as predictors of functional status and mobility 6 months after discharge from rehabilitation for older adults with hip fracture.DesignLongitudinal.SettingInpatient rehabilitation units of two community hospitals.ParticipantsAdults with hip fractures aged 65 and older who were discharged from a rehabilitation unit and had been living in the community before the fracture (N = 133).MeasurementsMini‐Mental State Examination (MMSE) score at discharge from rehabilitation was used to identify the presence and severity of cognitive impairment. Outcomes were measured using questions from two subscales of the Functional Independence Measure (Self‐Care Function and Functional Mobility) and the New Mobility Scale (NMS). Measurements were made at discharge from a rehabilitation setting and 3 and 6 months after discharge.ResultsPrefracture functional impairment was associated with worse outcomes throughout the 6 months after discharge and with lower rates of improvement, or in some cases decline, after discharge. Cognitive impairment was associated with worse outcomes throughout the 6 months after discharge but was only weakly associated with lower rates of improvement or decline. The Patient Centered Rehabilitation Model of care targeting persons with cognitive impairment (PCRM‐CI) intervention group had higher NMS scores after discharge than a usual care group.ConclusionAlthough cognitive impairment and prefracture functional impairment contribute to poor outcomes, prefracture functional impairment was more strongly associated with poor outcomes than cognitive impairment. There is evidence to show that individuals with cognitive impairment are able to regain their mobility, which suggests a need for postdischarge targeted interventions that include a focus on activities of daily living for older adults with cognitive impairment and functional impairment to stabilize gains from inpatient rehabilitation.
