Jones CA, Feeny DH. Agreement between patient and proxy responses during recovery after hip fracture: evidence for the FIM instrument.ObjectiveTo evaluate the agreement between patient and proxy responses of the FIM instrument at 4 different periods of time during the first 6 months after hip fracture.DesignProspective cohort study.SettingA large urban health region with 2 tertiary hospitals that treat hip fractures.ParticipantsPatients (n=137) who were 65 years or older, admitted to the health region with a primary diagnosis of hip fracture, who had Mini-Mental State Examination scores greater than 17. Family caregivers (n=137) participated as proxy respondents.InterventionsNot applicable.Main Outcome MeasureThe FIM instrument. Agreement was evaluated at each of the 4 assessments during the 6-month follow-up after hip fracture using intraclass correlation coefficient.ResultsFIM scores improved over the 6 months with the greatest improvement occurring within the first month of recovery. Agreement was higher for more observable activities than less observable ones. The magnitude of agreement improved over the 6 months with the proportion of clinically important systematic differences decreasing over time. Agreement for change scores was lower than the agreement at each of the 4 assessments.ConclusionsPatient-proxy agreement levels are acceptable; the agreement varies with the subscale and the recovery phase. Substitution of proxy for patient responses across time may be used guardedly when patient responses are missing.
