A study team led by IMPACT’s Multiple Principal Investigator Susan Mitchell, PhD, MPH recently published results of a Trial to Reduce Antimicrobial Use in Nursing Home Residents with Alzheimer’s Disease and Other Dementias (TRAIN-AD). The journal article and an accompanying editorial were published in JAMA Internal Medicine on July 12th.
Mitchell and colleagues conducted a cluster randomized clinical trial of a multicomponent intervention designed to improve management of suspected urinary tract infections (UTIs) and lower respiratory infections (LRIs) for nursing home residents with advanced dementia. The trial was conducted at 28 Boston-area nursing homes (14 per arm). The intervention, which targeted nursing home care providers, integrated best practices from infection diseases and palliative care for management of suspected UTIs and LRIs in residents with advanced dementia. Researchers observed a clinically significant 33% reduction in antimicrobial courses for suspected lower respiratory infections (LRIs) and urinary tract infections (UTIs) among participants living in facilities assigned to the intervention. Although this result was underpowered to show a statistically significant reduction, the TRAIN-AD study was unique in that it completed a rigorous evaluation of an intervention to reduce antibiotics in people with advanced dementia.
The study team found that despite a comprehensive training approach that included an in-person seminar, online course, management algorithms, communication tips, and feedback reports and a high adherence to the training, the intervention did not significantly reduce antimicrobial use among nursing home residents with advanced dementia. However, both Mitchell’s team and the commentary authors noted the potential of the intervention to yield more significant results when scaled up and applied to a broader range of nursing home settings.
The study results were accompanied by an invited commentary from Shiwei Zhou, MD and Pretti N. Malani, MD, noting these strengths and describing the study as a “a low-cost, low risk, scalable intervention that is associated with a reduction in inappropriate antibiotic prescriptions is worthy of replication” from a stewardship perspective.
