Prior research has demonstrated that limited English proficiency in Hispanic patients is associated with adverse health outcomes. The authors sought to compare the perception of primary care in resident practices between Spanish-speaking and English-speaking parents using a previously validated tool, the Parents' Perception of Primary Care. Using survey results from 19 CORNET sites nationwide, they compared mean scores for each primary care domain and the full scale between the groups using Student's t test. Multiple linear regression models compared outcomes controlling for demographic variables. Of the 2122 analyzable surveys, 490 (23%) were completed in Spanish and 1632 (77%) in English. The mean scores for each domain and the total scale were not statistically different between the 2 groups. After adjustment, Spanish-speaking parents rated communication significantly higher. Resident clinics may use systems to provide high quality care to Spanish-speaking patients, which may help other sites improve care.
