James G. Kahn, MD, MPH

Professor in Residence, Department of Epidemiology and Biostatistics (DEB) School of Medicine

Dr. Kahn is a Professor of Health Policy and Epidemiology at the Philip R. Lee Institute for Health Policy Studies, the Department of Epidemiology and Biostatistics, and Global Health Sciences, all at UCSF. Dr. Kahn is an expert in policy modeling in health care, cost-effectiveness analysis, and evidence-based medicine. His work focuses on the use of cost-effectiveness analysis to inform decision-making in public health and medicine.

He is particularly interested in the cost effectiveness of HIV prevention and treatment in resource-constrained global health settings. He has also evaluated interventions for malaria, diarrhea, gestational diabetes, congenital syphilis, pregnancy prevention, and orthopedic devices.

Dr. Kahn has served as consultant to WHO, PEPFAR, IOM and the World Bank on this topic. Dr Kahn’s research has been in Africa (Kenya, Tanzania, Uganda, South Africa), Russia, India and Mexico. Funding for his research projects has been awarded by the CDC, NIH, WHO, the Gates Foundation, the Axios Foundation, Novo Nordisk, and Vestergaard Frandsen.

Dr. Kahn is also interested in U.S. health care financing, in particular the administrative costs of insurance and billing, as well as single payer health care reform. He is the past President of California Physicians for a National Health Program.

Dr. Kahn is the lead instructor in global health economics and cost-effectiveness analysis at UCSF. He has participated in two National Academies of Science / Institute of Medicine studies.

Dr. Kahn’s current major projects are listed below.

Selected Projects: 

Global Health Intervention Review. In Phase 1, Dr. Kahn and team reviewed the efficacy of 150 prevention and treatment interventions for 8 diseases, posted as part of the Kaiser Family Foundation global health portal. In Phase 2, Dr. Kahn and team received NIH funding for a project entitled, “Global Health Comparative Effectiveness: A Data Synthesis Method Applied to HIV”. This study is building the “Global Health Decisions” web site. This site will translate research on the health benefits of HIV prevention and treatment interventions into locally-tailored data for HIV policies and programs. Users will interactively explore intervention portfolios, with resulting estimates of health impact, cost, and cost-effectiveness.

Scale-up of Community Integrated Prevention Campaigns. IPCs include HIV testing, bed nets to prevent malaria, and water filters to prevent diarrhea. Research in western Kenya suggests efficiencies and attractive health benefits and cost-effectiveness. Dr. Kahn led a satellite session at the recent AIDS conference in Washington DC on this topic, and is coordinating a set of research papers.
