Abstract Background The Geriatric Emergency Department (ED) Guidelines recommend screening older patients for need for evaluation by geriatric medicine, physical therapy (PT), and occupational therapy (OT), but explicit evidence that geriatric screening changes care compared to physician gestalt is lacking. We assessed changes in multidisciplinary consultation after implementation of standardized geriatric screening in the ED. Methods Retrospective single‐site observational cohort of older adult ED patients from 2019 to 2023 with three time periods: (1) preimplementation, (2) implementation of geriatric screening, and (3) postimplementation. Geriatric, PT, and OT consultations/referrals were available during all time periods. Descriptive analysis was stratified by disposition: discharged, observation and discharged, observation and hospital admission, and hospital admission. The independent variable was completion of three geriatric screening tools by ED nurses. The dependent variable was consultation and/or referral to geriatrics, PT, and OT. Secondary outcomes were disposition, ED revisits, and 30‐day rehospitalizations. Results There were 57,775 qualifying ED visits of patients age ≥ 65 years during the time periods: implementation increased geriatric screening from 0.5% to 63.2%; postimplementation, discharge patients who received screening had more consultations/referrals to geriatrics (1.5% vs. 0.4%), PT (7.9% vs. 1.9%), and OT (6.5% vs. 1.2%) compared to unscreened patients. Patients observed and then discharged had more consultations/referrals to geriatrics (15.1% vs. 11.3%), PT (74.1% vs. 64.5%), and OT (65.7% vs. 56.5%). Admitted patients had no change in consultation rates. Geriatric screening was not associated with a change in 7‐day ED revisits for discharged patients but was associated with decreased revisits for patients discharged from observation (11.6% vs. 42.9%, p < 0.001). Conclusion Geriatric screening was associated with increased consultations/referrals to geriatrics, PT, and OT in the ED and ED observation unit. This suggests that geriatric screening changes ED care for older adults.
