Personal History:

Raymond K. Cross, Jr., M.D.,M.S. is a board certified Gastroenterologist and Associate Professor of Medicine, Division of Gastroenterology and Hepatology, at the University of Maryland School of Medicine in Baltimore, Maryland. He also serves as Director of the Inflammatory Bowel Disease Program at the University of Maryland School of Medicine in Baltimore and is the Chief of the GI section at the Veterans Affairs, Maryland Health Care System Baltimore.

Dr. Cross received his undergraduate degree from Washington and Jefferson College in Washington, Pennsylvania, and his medical degree from the University of Pittsburgh School of Medicine in Pittsburgh, Pennsylvania. He completed his postgraduate training in Internal Medicine at the University of Maryland and Baltimore VA Medical Centers in Baltimore, Maryland, where he was chosen as Chief Resident. He performed his Gastroenterology fellowship also at the University of Maryland and Baltimore VA Medical Centers in Baltimore. In addition, Dr. Cross has obtained a Master of Science degree in Clinical Research at the University of Maryland School of Medicine, Department of Epidemiology and Preventive Medicine, in Baltimore.

Research Interests:

Dr. Cross has several research interests within the field of inflammatory bowel disease. First, he is testing a home telemanagement system for patients with ulcerative colitis (UC). Telemanagement is a home telemedicine system that assists providers in implementing practice guidelines and in monitoring their patients. Additionally, telemanagement systems assist patients in following action plans and in delivering patients focused education. Dr. Cross has previously tested the system in patients with inflammatory bowel disease, and was able to demonstrate that telemanagement was feasible in this population and that patients accepted the technology. The 12-month study will compare the telemanagement system to best available care in patients with ulcerative colitis. He is planning a separate trial to examine telemanagement in patients with Crohn's disease (CD).

Dr. Cross has evaluated the differences in disparities in outcomes both UC and CD by race at the University of Maryland and VA. He has published his findings in CD in Inflammatory Bowel Diseases, treatment disparities in CD and UC in Inflammatory Bowel Diseases and in Digestive Diseases and Sciences. A follow up study is being conducted to evaluated disparities in disease activity and quality of life in patients with inflammatory bowel disease.

Dr. Cross completed a health survey of physician practicing patterns and knowledge of infliximab side effects among gastroenterologists in Maryland and Washington D.C. The results have been published in Digestive Diseases and Sciences. He has completed a follow up national e-mail survey of American Gastroenterological Association members; the findings have been published in Inflammatory Bowel Diseases.

In addition, Dr. Cross recently completed a study of the impact of medication side effects on the quality of life and disease activity in patients with IBD. To evaluate medication side effects, he used a new questionnaire that had been used in patients with asthma and depression. The findings have been published in the Journal of Clinical Gastroenterology.

Clinical Speciality:
