Functional status change for patients with Foot and Ankle impairments

This is a patient-reported outcome performance measure (PRO-PM) consisting of an item response theory-based patient-reported outcome measure (PROM) of change in functional status (FS) for patients aged 14 years and older with foot and ankle impairments. The change in FS is assessed using the FOTO Lower Extremity Physical Function (LEPF) PROM. The measure is adjusted to patient characteristics known to be associated with FS outcomes (risk adjusted) and used as a performance measure at the patient, individual clinician, and clinic levels to assess quality. Scores are reported on a 0 to 100 continuous scale with higher scores indicating better FS. The LEPF items relate directly to the Mobility and Self-care constructs within the Activities and Participation domain of the International Classification of Functioning, Disability and Health.
Additional information on the different development phases of the LEPF PROM are described in the testing attachment (section 1.5).
