Özet
Objectives: This study assessed whether reducing immediate perioperative anticholinergic burden improves functional recovery in older patients undergoing coronary artery bypass grafting (CABG). Design: Prospective randomized controlled study. Setting: Single-institution tertiary care hospital. Participants: One hundred twenty-two patients aged ≥60 years with preoperative Anticholinergic Cognitive Burden scores ≥3. Interventions: Patients were assigned to either standard anesthetic and/or analgesic care including anticholinergic drugs (standard group) or a deprescribing strategy avoiding perioperative anticholinergic anesthetic and analgesic drugs (deprescribing group). Measurements and Main Results: Primary outcomes were functional recovery on postoperative day 90 assessed using the Katz Index and the Clinical Frailty Scale. On postoperative day 90, full independence (Katz Index score of 6) was significantly more frequent in the deprescribing group than in the standard group (75.0% v 41.1%, p < 0.001). Frailty scores were significantly lower in the deprescribing group at 90 days (median, 3 [interquartile range (IQR), 3-3] v 4 [IQR, 3-4]; p < 0.001). Multivariate logistic regression identified perioperative use of anticholinergic anesthetic and analgesic drugs as an independent predictor of 90-day total complications (odds ratio, 2.430; 95% confidence interval, 1.031-5.726; p = 0.042). Within-group analyses showed decreased frailty scores and increased Katz Index scores from baseline to day 90 in the deprescribing group (p < 0.001 for both), whereas the standard group showed increased frailty (p < 0.001) with no significant change in Katz Index scores (p = 0.317). Conclusions: In older CABG patients, immediate perioperative deprescribing of anticholinergic medications improved 90-day functional recovery trajectories and was associated with fewer cardiac and pulmonary complications. Anticholinergic burden may represent a modifiable perioperative risk factor that should be routinely addressed in surgical care pathways to optimize outcomes in older adults.
