This is a patient-reported outcome performance measure (PRO-PM) consisting of a patient-reported outcome measure (PROM) of risk-adjusted functional status (FS) change in balance confidence for patients aged 14+ with balance impairments. The change in FS is assessed using the FOTO Balance Confidence, an item-response theory-based PROM derived from the 16-items of the Activities-specific Balance Confidence (ABC) Scale©, scored using the T-score metric (mean=50, SD=10), with higher scores representing higher balance confidence. Patient responses to ABC Scale© items may be used to directly score Balance Confidence PROM, thus allowing clinicians flexibility of choice of PROM used in routine clinical care without adding to patient response burden. In order to fairly measure performance between providers, this quality measure is risk-adjusted to patient characteristics known to be associated with FS outcomes and used as a performance measure at the patient and provider levels to assess quality. 1. © Dr. Anita M.
