K. John McConnell, PhD
K. John McConnell, PhD, is the Principal Investigator of this NIH-funded research to assess the economic impacts of Oregon's transition to CCOs. Dr. McConnell directs the Center for Health Systems Effectiveness and is an Associate Professor in the Departments of Emergency Medicine and Public Health & Preventive Medicine at Oregon Health & Science University. He is a health economist whose work has focused on state health policy, behavioral health, and quality improvement.

Dr. McConnell's work has been noteworthy for his close collaboration with key stakeholders, frequently working with provider groups and association or serving as an advisor to the Oregon Legislature and state policy makers. He was the Chief Economic Advisor to the Oregon Health Fund Board from 2007 to 2009. Recent experience with policy and economic analysis includes analyses of the impacts of changes in co-payments and benefit structures on Medicaid recipients; the effects of comprehensive mental health and substance abuse "parity" legislation; and a national study of the dissemination and effectiveness of "Lean" management practices in over 600 cardiac units throughout the country.

Deborah Cohen, PhD

Deborah Cohen, PhD
Deborah Cohen, PhD is a co-investigator on this study. She is an Associate Professor in the Department of Family Medicine at Oregon Health & Science University. Dr. Cohen will be leading a qualitative study to learn how the CCO transformation affects all stakeholders including hospitals, medical practices, clinicians and patients.

Dr. Cohen is a communication scientist whose work has focused on examining primary care systems and health care quality, and identifying practice systems and approaches that support the translation of basic research findings into practice improvements. Through this work, Dr. Cohen has developed a mixed method approach to assess change and improvement in clinical settings. Important features of this approach include using qualitative methods to identify successful quality improvements and to gather the process data – how interventions were 'really' implemented — that is necessary for disseminating and translating successful interventions to other settings, fostering collaboration among frontline clinic and organization members implementing interventions and researchers, and collecting and sharing research data in real time in order to foster learning through evaluation. Dr. Cohen is a qualitative researcher by training and has specific expertise in a qualitative approach called conversation analysis. She enjoys working on multidisciplinary research teams. In addition, Dr. Cohen created a web-based resource for the Robert Wood Johnson Foundation that is designed for people with an interest in qualitative research (, and Dr. Cohen is an Associate Editor for the Annals of Family Medicine.

Anna Marie Chang, MD, MSCE
Anna Marie Chang, MD, MSCE is co-investigator on this study. She is Assistant Professor in the Department of Emergency Medicine at Oregon Health & Science University. She will conduct a mixed-methods study to identify CCO, ED and patient level factors that lead to changes in ED utilization and hospitalizations.  Using interviews and surveys, she will identify the key strategies as proposed by CCOs to reduce ED visits for asthma, heart failure, and COPD.  Further interviews and surveys will determine how these key strategies are being implemented at the ED level.

Dr. Chang's research interests are in studying patients with acute cardiopulmonary conditions and transitions of care.  Heart failure, asthma, chronic obstructive pulmonary disease (COPD), and ischemic heart disease account for a significant proportion of emergency department (ED) visits, hospital admissions and repeat ED visits, and have a high rate of readmissions. Thus, reducing ED utilization and admissions for these conditions in the Medicaid population will greatly impact overall ED use, and present research has identified a lack of quality connections and transitions from hospital-to-home for patients with these specific conditions.
