Dr. Horton joined Christiana Care in 2007 as director of the Consult Service at Wilmington Hospital. The next year, he helped launch Project Engage at Wilmington Hospital. This program embeds a peer engagement specialist at the hospital to reach substance-addicted patients when they most need help and provide a clear pathway to treatment. Project Engage has drawn national attention for its innovative approach and success in reducing health care costs and utilization by reducing emergency room visits and hospital stays.

Also receiving national recognition, from the Institute for Healthcare Improvement and the Innovations Exchange of the national Agency for Healthcare Research and Quality, is the work of the Christiana Care Alcohol Withdrawal Working Group, which Dr. Horton chairs. This group developed and implemented protocols for screening and treating hospital patients for alcohol withdrawal.

Dr. Horton is also an experienced teacher. In his role as an internal medicine faculty member, he trains Department of Medicine residents in inpatient and outpatient work. He also teaches second- and third-year students from Jefferson Medical College of Thomas Jefferson University in Philadelphia.

Prior to joining Christiana Care, Dr. Horton worked for 15 years as medical director and vice president of the New York-based Phoenix House Foundation, the nation’s largest nonprofit substance abuse treatment program. His primary roles there were development of health services and serving as national spokesperson.

Dr. Horton’s areas of expertise include: addiction and primary care; addiction screening and interventions in hospital and primary care settings; detoxification programming and comorbidity. He is a frequent lecturer on these topics for Christiana Care staff as well as across the country and world. He has provided testimony before the U.S. House and Senate and lectured in Taiwan and Germany. He is regularly interviewed by the national press, including The New York Times and the Associated Press, and has appeared more than 40 times on local and national television and radio, including CBS News, ABC News and CNN.

Dr. Horton’s research on the science and treatment of addiction is well represented in the academic literature through numerous articles published in peer-reviewed journals and book chapters.

Dr. Horton is involved in numerous professional organizations. He is an executive committee member and national steering committee representative for the Delaware Valley Node of the Clinical Trials Network of the National Institute on Drug Abuse, part of the National Institutes of Health, and a member of the Governor’s Advisory Council for the Delaware chapter of the American College of Physicians. He is a diplomate for the American Board of Internal Medicine and the American Board of Addiction Medicine.
