Enhanced Recovery After Surgery (ERAS) programs significantly lower the incidence of postoperative delirium.

• Overall incidence of delirium dropped by 62% (RR = 0.38).
• First-day delirium occurrence reduced by 80% (RR = 0.20).
• Hospital stays shortened by an average of 4.6 days (MD = -4.61).

Implementing ERAS can lead to faster recovery and fewer complications.

• Patients experienced quicker ambulation (MD = -1.53) and improved cognitive scores (MD = 1.95).
