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 jaw functional status for patients aged 14+ with impairments related to jaw function. The change in FS is assessed using the FOTO Jaw Functional Status Scale (JFSS), an item-response theory (IRT)-based PROM derived from 13 of the 20 items of the Jaw Functional Limitation Scale (JFLS).1, 2 The JFLS is a condition-specific PROM for functional limitations in the masticatory system.3 The 13-item FOTO JFSS is scored using the T-score metric (mean=50, SD=10), with higher scores representing higher functional status. The JFSS PROM can be administered using either computerized adaptive test (CAT)4 or a 6-item short form. 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.
