Cost of Preventable Hospitalizations Associated With Diabetes on the Rise


December 14, 2018

The cost of diabetes-related preventable hospitalizations in the United States rose 1.6% annually between 2001 and 2014 — mostly due to an increase in the number of people with diabetes as well as the rising cost of hospital stays. Researchers published their findings online in Diabetes Care.

The study was based on data from the US National Inpatient Sample for adults for the years 2001 through 2014.

Of the 1.6% annual increase in the estimated total cost of diabetes-relation preventable hospitalizations, researchers said 75% of that increase was due to an increase in the number of hospitalizations. That rise in hospitalizations, in turn, was the result of a 3.8% increase in people with diabetes combined with a 2.6% decrease in the hospitalization rate.

The remaining 25% of the annual increase in hospitalization costs was due, according to the study, to the increased cost of a hospital stay (although the mean length-of-stay decreased by 1.3%, researchers reported).

The study also looked at cost trends for factors underlying diabetes-related preventable hospitalizations. The cost of short-term complications increased annually by 4.2%. The cost of lower-extremity complications increased annually by 1.9%, and the cost of long-term complications rose annually by 1.5%. The cost of uncontrolled diabetes, on the other hand, declined annually by 2.6%.

“The underlying factors identified in our study,” researchers wrote, “could lead to efforts that may lower future hospitalization costs.”
