Abstract:
Study examined the level of agreement between self-reported dose and the dose reflected in administrative records of outpatient physical, occupational, and speech therapies at 6 and 12 months after severe traumatic brain injury (TBI). Sixty-five people with severe TBI living in the community provided 6-month data; 54 provided 12-month data. Participants were queried about therapy doses using a structured interview, either alone or assisted by relatives, with responses compared to administrative records of scheduled and billed therapy appointments using intraclass correlation coefficients (ICCs). Linear regression models were used to predict accuracy from demographic variables and cognitive status. Results showed ICCs were in the moderate range at 6 months, but were more variable, with some in the poor range, at 12 months. Agreement was higher for scheduled than for billed (attended) appointments. Assisted and unassisted patients provided comparable agreement with records. No demographic factors were associated with accuracy, but lower cognitive Functional Independence Measure scores, as hypothesized, tended to predict lower agreement at 6 months. People with severe TBI can provide reasonable estimates of commonly prescribed outpatient therapy doses at 6 months post injury. Accuracy may be improved by inviting patients to request assistance from relatives and by asking them to consider attended (versus scheduled) sessions.
