OBJECTIVE: To evaluate the change of geriatric anticholinergic cognitive burden (ACB) over acute admission for fall, fracture, or altered mental status (AMS) with a secondary endpoint of associated 30-day all-cause readmission. DESIGN: Retrospective, single-center chart review. SETTING: An academic, 636-bed level-I trauma and tertiary care hospital in Texas. PATIENTS, PARTICIPANTS: Participants at least 65 years of age admitted for acute fall, fracture, or AMS between January 1, 2014, and August 31, 2018. A total of 265 participants were included; average age was 83 years, with 56% female. MAIN OUTCOME MEASURES: Change in ACB of home medications from hospital admission to discharge. RESULTS: At admission, ACB averaged 2.6 with 43.4% of participants having clinically significant scores, defined as ACB greater than or equal to 3. Overall, ACB decreased by 0.1 by discharge with 63.8% and 13.9% of participants having no change and increases in their ACB over admission, respectively. Clinically significant anticholinergic burden at discharge was significantly associated with 30-day all-cause readmission (P<0.001). CONCLUSIONS: Anticholinergic burden in older people admitted for fall, fracture, or AMS is not consistently intervened upon in this acute care setting. Strategies to optimize deprescribing in this setting are needed.
