Residents of long-term care facilities are particularly vulnerable to patient safety risks. This systematic review including 66 studies evaluated tools used to identify adverse events in intermediate and long-term care centers (ILCCs). The authors found that most tools are designed to identify specific adverse events or safety risks (such as medication errors, falls, or infections). Common adverse events impacting this population include adverse drug events, delirium, malnutrition, pressure ulcers, and infections.
