Characteristics of outpatient emergency department visits of nursing home residents: an analysis of discharge letters

Background Unplanned emergency department (ED) visits of nursing home residents (NHR) are common, with many transfers not leading to hospitalization. However, there is little research on what diagnostic and therapeutic measures are performed during visits. Aims We analyzed underlying diagnoses, characteristics and performed medical procedures of unplanned outpatient ED visits by NHR. Methods We conducted a multi-center study of 14 nursing homes (NHs) in northwestern Germany in 03/2018-07/2019. Hospital transfers were documented by nursing staff using a standardized questionnaire for 12 months. In addition, discharge letters were used to collect information about the respective transfer, its reasons and the extend of the medical services performed in the ED. Results A total of 161 unplanned ED visits were included (mean age: 84.2 years; 68.3% females). The main transfer reasons were trauma (59.0%), urinary catheter and nutritional probe problems (overall 10.6%; male NHR 25.5%) and altered mental state (9.9%). 32.9% where discharged without imaging or blood test prior. 67.4% of injured NHR (n = 95) required no or only basic wound care. Catheter-related problems (n = 17) were mainly treated by changing an existing suprapubic catheter (35.3%) and by flushing the pre-existing catheter (29.4%). Discussion Our data suggest that the diagnostic and therapeutic interventions performed in ED, often do not exceed general practitioner (GP) care and many ED visits seem to be unnecessary. Conclusion Better coordination and consultation with GPs as well as better training of nursing staff in handling catheter problems could help to reduce the number of ED visits.
