August 19, 2025: INSPIRE Sees Sustained Reductions in Use of Extended-Spectrum Antibiotics

Logo for the INSPIRE Demonstration ProjectA new analysis from the INSPIRE research team found that automated prompts to improve judicious use of antibiotics for hospitalized patients led to sustained reductions in the use of extended-spectrum antibiotics.

The findings were reported in a research letter in JAMA.

INSPIRE, an NIH Collaboratory Trial, consisted of 2 cluster randomized trials that used personalized clinical decision support to improve judicious antibiotic prescribing for non–critically ill hospitalized patients with abdominal or skin and soft tissue infections during the first 3 days of hospitalization. The research program also included 2 other trials, which evaluated the same intervention for hospitalized patients with pneumonia and urinary tract infection.

In the new analysis, 65% to 84% of the reductions achieved in the use of extended-spectrum antibiotics in the first 3 days of hospitalization persisted through the remainder of the hospital stay.

“These findings suggest that investing in stewardship for initial antibiotic selection, rather than primarily focusing on de-escalating antibiotics once started, would reduce unnecessary extended-spectrum antibiotics for millions of patients in US hospitals annually,” the authors wrote.

INSPIRE was supported within the NIH Pragmatic Trials Collaboratory by a grant from the National Institute of Allergy and Infectious Diseases. The primary results were reported this year in JAMA Internal Medicine and JAMA Surgery.
