Patti Katz, Ph.D., is Professor in Residence in the Department of Medicine at UCSF. Dr. Katz’s earlier research focused on costs and resource use associated with specific conditions and technologies, and on outcomes research and evaluation. She collaborated on projects investigating the costs of kidney and liver transplantation, pelvic inflammatory disease, ectopic pregnancy, neonatal care, and asthma, and also engaged in research that assessed health care quality and outcomes, the impact of hospitalist systems and variations in health insurance on health outcomes. She was Associate Director of a Program Project (P01) funded by NIH (NICHD) entitled, “Individual, Family, and Societal Outcomes of Infertility,” Director of the Methodology Core for that P01, and was Principal Investigator of a project entitled, “Economic and Social Costs of Infertility” within the P01.

For the past decade Dr. Katz’s research has focused the development of disability in life activities and the role of functional decline, defined both traditionally and to include a broader range of life activities, as a risk factor for the development of depressive symptoms. She has received NIH funding to examine the relationship of different ways of coping with rheumatoid arthritis (RA) to functional decline, health status, and health care utilization; parenting disability and psychological well-being among individuals with RA; and disability in valued life activities and psychological outcomes among persons with RA, systemic lupus erythematosus, and obstructive lung disease. More recently, her research has examined the role of body composition and obesity in development of disability among individuals with RA and lupus.  In 2013, she began a randomized controlled trial of a physical activity intervention to reduce fatigue among individuals with rheumatoid arthritis.
