This study investigated whether implementing the Preferences for Everyday Living Inventory (PELI) could serve as a predictor of nursing home quality, as defined by deficiencies. Data were analyzed from 1,300 nursing home year observations, merged from six Ohio nursing home sources. Complete PELI implementation (i.e., gathered and used PELI information to guide care delivery and quality Improvement) was related to lower deficiency scores and an increased probability of having a deficiency score of zero, indicating that person-centered care stands to improve quality outcomes.
