Preexisting cognitive impairment, such as mild cognitive impairment, is common in many elderly patients who undergoing major surgeries. Accumulating evidence has demonstrated that preexisting cognitive impairment is associated with increased mortality, increased incidence of postoperative complications, decreased quality of life, and worse outcomes. However, few studies have evaluated the relationship between preexisting cognitive impairment and cognitive trajectories and clinical outcomes.

Cognition changes
Cognitive function was assessed at baseline before the elective operation and one year in all subjects using the Mini-Cog test by a member of a trained research team.
1 year
Patients in this group have normal cognition as assessed by the validated Mini-Cog test before the elective operation.
Patients in this group have impaired cognition as assessed by the validated Mini-Cog test before the elective operation.
Patients were 65 years and older undergoing an elective operation on the general, noncardiac thoracic, urologic, and vascular surgical services.
