Abstract Introduction NICE Clinical Guideline CG103 states that adults aged 65 and older should be screened for delirium within 48 hours of emergency hospital admission. The Geriatric Medicine Research Collaborative (GeMRC)'s World Delirium Day data from 2019 showed an average screening rate of 27% nationally. After an inpatient fall on the Medical Assessment Unit resulted in hip fracture for a patient who had not been screened for delirium with the recommended 4 A's Test (4AT), we decided to collect data on screening rates and devised a way of improving these. Method Baseline data was collected examining patient notes of adults over 65 years currently on the Medical Assessment Unit who had been seen by a doctor. The intervention was a teaching session on delirium for the junior doctors on the ward, focusing on the adverse prognostic features of delirium and importance of clear diagnosis with onward communication to the patient's GP. Repeat data collection was done following this. Results 55% of all patients on the ward throughout data collection were over 65 years of age. A total of 79 patient notes were examined. The baseline rate of delirium screening with a completed 4AT pre-intervention was 25%. Post-intervention this increased to 41.3%. Without further education this fell to 26.9%. Most of the unscreened patients showed incomplete 4ATs or only the Abbreviated Mental Test (AMT) section completed. Conclusion Integrating delirium teaching into departmental teaching on Acute Medical Units can increase the rates at which delirium is diagnosed, which is important for the patient's clinical trajectory and prognosis, both for their inpatient stay and long term. Further work is required to show sustained improvement. Future work may include assessing the rate of documented diagnosis out of those who clinically fit the criteria.
