Prior to joining the Institute in 2003, Dr. Blanchfield had conducted health services research for 15 years both as an independent consultant and with the Center for Health Affairs at Project Hope analyzing the financial implications of broad policy changes on hospital financial viability, charity care, specific hospital programs, and capital investment.

Her expertise in hospital payment systems, financial analysis, business practices, and quality measurement and improvement is complemented by an array of research skills. These include case study techniques, program and policy evaluation, econometric modeling, and the use of financial data and audited financial statements for health services research.
