GI, liver, and pancreatic diseases cost the U.S. health care system about $120B per year and account for approximately 250,000 annual deaths, according to a "conservative" estimate from a recent analysis.
These figures emphasize the need for more research funding in the area, along with additional clinical and public health initiatives, reported lead author Anne F. Peery, MD, of the University of North Carolina School of Medicine, Chapel Hill, and colleagues.
"Reports detailing the burden of GI diseases are necessary for clinical research, decision making, and priority setting," the investigators wrote in Gastroenterology. "Our aim was to describe health care use, expenditures, and research funding across GI, liver, and pancreatic diseases in the United States."
Peery and colleagues analyzed data from 14 sources, including the National Institutes of Health; the Centers for Disease Control and Prevention; the National Ambulatory Medical Care Survey; and others. GI-specific outcomes included mortality, readmissions, hospitalizations, office-based visits, and emergency department visits. The investigators also characterized trends in cancers, organ transplants, and GI endoscopy, as well as GI-specific health care costs and NIH research funding. Annual findings were presented for various periods.
Total GI health care spending was $119.6 billion in 2018, down from $135.9 billion in 2015. The top five most costly conditions were biliary tract diseases ($16.9 billion), esophageal disorders ($12.1 billion), abdominal pain ($9.5 billion), abdominal hernias ($9.0 billion), and diverticular disease ($9.0 billion). The investigators noted that medication costs were particularly high for two categories: inflammatory bowel diseases and esophageal disorders, which had prescription drug costs relative to total expenditures of 71% and 53%, respectively.
