Effectiveness of comprehensive geriatric assessment-based intervention to reduce frequent emergency department visits: A report of four cases

A small number of clustered visits by emergency department frequent users (EDFUs) may over-consume emergency care resources. We report the effectiveness of comprehensive geriatric assessment (CGA)-based multidisciplinary team (MDT) care for four EDFUs, in reducing ED visits. Case 1 had visited the ED twice/month due to chest discomfort. Her ED visits were significantly reduced to 0.2 visits/month following CGA-based MDT care. Case 2 had failed back surgery syndrome and bipolar disorder. His ED visit was reduced from 2.8 visits to 0.8 visits/month following CGA-based MDT intervention. Case 3 had chronic obstructive pulmonary disease, heart failure, and urinary incontinence, with a urinary catheter in place. He made 31 ED visits (5.1 visits/month) before his lung cancer and depression were discovered by CGA. He died 2 months later. Case 4 made 27 ED visits (2.7 visits/month) due to dizziness. His problems of early dementia and neglect were identified by CGA, and he visited the ED only once following MDT intervention. In conclusion, CGA-based MDT intervention successfully reduced ED visits among these EDFUs, but further investigation is needed to evaluate the effectiveness of geriatric services in the ED.
