You are invited to attend Rebecca Carter’s Dissertation Proposal on Wednesday April 19th at 10am in WG-86. The title of her proposal is Antibiotic Use in Nursing Homes.
Description: Antibiotic-resistant bacteria cause over 2.5 million infections and 23,000 deaths annually. Nursing homes, where experts estimate that 25% to 75% of antibiotic prescriptions are inappropriate or unnecessary, contribute to the burden of antibiotic-resistant bacteria. Antibiotic stewardship, which seeks to minimize inappropriate or unnecessary antibiotic use, is critical to combating antibiotic-resistant bacteria. Antibiotic stewardship is urgently needed in nursing homes to improve resident outcomes and to reduce selection for antibiotic-resistant bacteria across all healthcare settings.
There is a paucity of evidence for successful antibiotic stewardship in nursing homes, the majority of which is derived from clinical interventions. Little is known about benchmarking antibiotic use or characterizing antibiotic use patterns in nursing homes, let alone how that use corresponds with engagement in principles of antibiotic stewardship. We propose an investigation that will evaluate antibiotic use among community-based nursing homes, characterize said nursing homes based on their antibiotic use, and investigate the organizational culture of the nursing homes including the extent of their engagement with antibiotic stewardship.
We propose to accomplish this investigation through a study design grounded in behavioral theory, with a novel approach that integrates existing, public, and survey-based data. Our central hypothesis is that nursing homes with a low rate of antibiotic use will have an interconnected organizational culture in comparison to nursing homes with a high rate of antibiotic use.
