Dr. McClellan is a health services researcher with a strong interest in examining interventions with the potential to improve the effectiveness of the health care system in the United States. Through this research agenda, he specifically aims to better understand how organizations adopt to new circumstances and how those changes may influence patients and providers of health care. Dr. McClellan’s research emphasizes that innovations for health care organizations are not “one size fits all.” Dr. McClellan completed his Ph.D. in the health services and policy analysis program at the University of California, Berkeley, with a concentration in organizational behavior.  While at UC Berkeley, he worked closely with the National Study of Physician Organizations, under Dr. Stephen Shortell. Dr. McClellan wrote his dissertation on the topic of organizational and market factors associated with the adoption of health information technology within two national cohorts of physician organizations, before and after the passage of meaningful use policy. Additionally, his paper recently appearing in the Journal of the American Medical Informatics Association examined factors associated with the adoption of health information technology functionalities by physician practices and the use of those functionalities once adopted by physicians within practices. Dr. McClellan also has a strong interest in studying the accessibility of mental healthcare. Working with Dr. Lonnie Snowden, he has published two studies examining the effects of language assistance programming on the accessibility of mental health care for Medicaid-eligible persons with limited English proficiency in California.
