Dr. Lanlan Xu

Dr. Lanlan Xu (Ph.D. Public Policy, Indiana University) is a health economist with subject matter expertise in Medicare and Medicaid population, long-term supports and services to older adults and disabled, maternal and child health, and immigrant health. Dr. Xu has extensive training in advanced econometrics, particularly in economic modeling for policy analysis and quasi-experimental methods for program evaluation. Dr. Xu is experienced in using administrative and survey data to develop quality and cost measures, simulate policy outcomes, and assess program impact. Additionally, she has experience in using Meta-analysis to systematically review academic literature and policy documents.

Dr. Xu’s research at IMPAQ focuses on assessing the impact of changes in care delivery and financing on health care quality, cost, equity, and patient outcomes. Currently, Dr. Xu is working on two impact evaluation projects: the Evaluation of the Medicare Demonstration Community-Based Care Transitions Program and the Evaluation of the Maryland Patient-Centered Medical Home Demonstration. Both of these projects involve a mixed methods evaluation design using program and claims data in a quasi-experimental framework.

In addition to quantitative evaluation work, Dr. Xu has also served in leadership roles for other program monitoring and compliance review projects for CMS. As the project director of the Medicare Part D Organization’s Performance Metrics and Composite Scoring Report Card, Dr. Xu oversees all aspects of this project in designing and carrying out ad-hoc analyses to support CMS with decisions on the choices of star rating measures, display measures and compliance thresholds.

Prior to joining IMPAQ, Dr. Xu conducted research in the School of Public and Environmental Affairs, Indiana University, the Indiana University Public Policy Institute, and the National Association of Home Builders. She has published a number of research papers and presented at numerous conferences such as the annual research meetings of AcademyHealth, the Association for Public Policy Analysis and Management (APPAM), Population Association of America (PAA), and the Midwest Political Science Association (MPSA).
