The BPS scale categorizes the receipt of services as excellent, good, fair, or poor.', 'Most children received excellent (34.9%) or good (31.5%) care, but many received fair (24.9%) or poor (8.7%) care. Sociodemographic and health care factors such as race/ethnicity, insurance, and practice setting were not associated with BPS levels. Higher BPS scores were associated with parental reports of longer well-child visits, more counseling regarding family and community risk factors, lower rates of delayed or missed care, and greater satisfaction.'] Does prevalence and correlate of high-quality basic pediatric preventive care?
