Background: High-cost health care users use disproportionate amounts of health care resources relative to the typical patient. It is unclear to what extent poor-quality prescribing, including potentially inappropriate prescribing (PIP), may be contributing to their adverse outcomes and health utilization costs.
Objectives: To evaluate the prevalence of PIP and to explore its impact in older adult high-cost health care users.
