This is a patient-reported outcome performance measure (PRO-PM) consisting of a patient-reported outcome measure (PROM) of risk-adjusted change in functional status (FS) for patients aged 14 years+ with lymphedema or other causes of edema. For patients with such conditions affecting the leg, foot, groin, or lower trunk regions, the change in FS is assessed using the FOTO Lower Quadrant Edema (LQE) FS PROM. For patients with such conditions affecting the arm, hand, chest, or breast body regions, the change in FS is assessed using the FOTO Upper Quadrant Edema (UQE) FS PROM. PROM scores were scaled to the 0-100 metric, with higher scores representing higher perceived functional status. In order to fairly measure performance between providers, the 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.
