Defining and Categorizing Nonpharmacologic Interventions in the Older Population: A Systematic Review.

Objectives: Nonpharmacologic interventions (NPIs) constitute an important part of treatment for older adults, cover a broad and diverse range of interventions, and have advantages over pharmacologic interventions (eg, limited adverse side effects). However, an unambiguous definition of NPIs is still lacking. Defining NPIs may facilitate research on this topic and enhance comparability of results between studies, and might help to face the challenges of recognition, acceptation, funding, and implementation.
