Improving Delirium Care: A Retrospective Audit of Early Detection and Management Practices

Abstract

Abstract Background Delirium, an acute change in cognition, consciousness, attention, and perception, is prevalent among older adults in hospitals. Patients with delirium experience longer hospital stays, higher fall risks, increased mortality, and greater care needs upon discharge. However, delirium is under-recognized, with up to 50% of cases missed. With an aging population, the need for improved delirium recognition and management is critical. Methods We conducted a retrospective audit on the charts of 47 patients over the age of 65 on two General Medical Wards at an Irish Model 3 hospital. We assessed medical admission proformas and notes to evaluate delirium recognition and management within the first 24 hours. The audit measured compliance with the 4AT cognitive screening tool, documentation of delirium and risk factors, non-pharmacological management, and antipsychotic use against HSE National Guidelines. Data was analysed in Excel. Results 47 patients with a median age of 80 years, 51% (n=24) male and 49% (n=23) female, were captured. Cognitive screening within 24 hours was performed in 34% (n=16) of patients, with 75% (n=12) showing abnormal results. Delirium was documented in 8.5% (n=4) of patients, and 50% (n=2) of these had a 4AT score recorded. 15% (n=7) were prescribed new antipsychotics within 24 hours, with 57% (n=4) lacking a formal delirium diagnosis. Conclusion This audit reveals deficiencies in initial cognitive screening and delirium recognition among high-risk patients. Only 8.5% of the cohort was identified with delirium compared to national statistics that suggest up to 31% of older patients are affected upon admission. Compliance with cognitive screening and diagnostic tool use was poor. Antipsychotic prescribing without a documented delirium diagnosis was prevalent, highlighting the need for improved diagnostic accuracy and non-pharmacological management. We plan to introduce a “Delirium Tool” for 4AT assessments and “PINCH-ME” risk-factors, alongside regular education sessions. A re-audit will measure improvements in care and outcomes.
