As an expert in the use of payment and quality incentives in healthcare, Dr. Chien is especially committed to improving care delivery for vulnerable populations like those who are socioeconomically disadvantaged, racial/ethnic minorities, children, and those with disabilities. To date, she is the only general pediatrician to have received a K08 career development award to study payment incentives from the Agency for Healthcare Research and Quality (AHRQ), through which she examined the effectiveness of pay-for-performance (P4P) incentives in the federally qualified health center setting.
