NIA AD/ADRD Health Care Systems Research Collaboratory (IMPACT)

The NIA AD/ADRD Collaboratory will provide the national infrastructure necessary to catalyze and support embedded pragmatic clinical trials of non-pharmacological interventions for persons with dementia. By convening national experts to provide consultation and guidance to Collaboratory-funded pilot projects and NIA-funded trials, the Collaboratory has the potential to transform care delivery, quality, and outcomes for millions of Americans suffering with AD/ADRD.

Principal Investigator

Trial to Reduce Antimicrobial Use in Nursing Home Residents with Alzheimer's Disease and Other Dementias (TRAIN-AD2)

The research aims to develop and implement a pragmatic trial of a practice-level intervention to reduce antimicrobial use in nursing home residents who are exhibiting AD or related dementias.
