About Leslie

Leslie Conwell has expertise in qualitative research, quality measurement, and health information technology and has extensive experience in managing complex federal contracts.

As part of the evaluation of the second round of the Health Care Innovation Awards, she oversees the implementation evaluation for 13 awardees. Additionally, her recent work has focused on learning systems initiatives from the Center for Medicare & Medicaid Innovation (CMMI) to support accountable care organizations (ACOs) and the development of hospital- and physician-based quality measures for the Centers for Medicare & Medicaid Services (CMS).

Conwell oversaw the development and launch of a learning system to support CMMI’s proposed End-Stage Renal Disease Seamless Care Organizations and Medicare Shared Savings Program ACOs, including creating a structure for training and peer-to-peer learning to help the Medicare ACOs achieve the triple aim of better care for patients, better health for populations, and lower health care costs. She also oversaw the design and development of a dashboard system to facilitate learning and monitoring among Pioneer ACOs.

Additionally, Conwell has been involved in all stages of the quality measure life cycle, from measure development to implementation. She was recently the deputy project director of a contract to lead the development of new electronic clinical quality measures (eCQM) and the retooling of approximately 100 existing quality measures into eCQMs in support of the meaningful use of electronic health records by clinicians for CMS. In her other measure development work, Conwell has overseen efforts by partners to develop and test quality-of-care measures for prospective payment system-exempt cancer hospitals and inpatient psychiatric facilities. She has also been task lead for the production of risk-adjusted hospital mortality and readmission rates and hospital feedback reports on these measures, for public reporting on the Medicare Hospital Compare website.

Before joining Mathematica in 2007, Conwell worked at the Center for Studying Health System Change, Covance, and the Segal Company. She holds a Ph.D. in health services research from the Johns Hopkins University.
