Longevity & AgingPLATO-11 Gives Clinicians a Fast, Validated Way to Track Sleep Apnea Treatment
Researchers developed and validated PLATO-11, an 11-item patient-reported outcome (PRO) tool designed to monitor obstructive sleep apnea (OSA) symptoms over time in clinical settings. Built following FDA guidance for PRO measures, the tool underwent rigorous multi-phase development including patient concept elicitation, cognitive interviews, pilot testing at 10 AASM-accredited sleep centers, and psychometric validation in 560 adults with OSA plus 40 controls. PLATO-11 covers both daytime and nighttime OSA symptoms with a 7-day recall window, completes in under 4 minutes, and demonstrated excellent internal consistency, test-retest reliability, and responsiveness to treatment-related symptom change. Available in paper and electronic formats with a Spanish translation, it is now publicly available for clinical use.
