Study Type

  • Study Type: Observational
  • Study Design
    • Time Perspective: Prospective
  • Study Primary Completion Date: October 2015

Detailed Description

At the preoperative visit, the co-researcher invites 322 general and vascular patients (male 190, female 132) and 260 urological patients (male 220, female 40) who meet the inclusion criteria to join the study. The process of the project is explained to the interested patients in details before an informed consent is obtained. All participants are interviewed by using the Montreal Cognitive Assessment test. The history of drug used preoperatively (medication reconciliation) has also been recorded.

Clinical Trial Outcome Measures

Primary Measures

  • Incidence of mild cognitive impairment in preoperative geriatric patients
    • Time Frame: 1 Year

Secondary Measures

  • Relationship between mild cognitive impairment and drug used preoperatively in geriatric patients
    • Time Frame: 1 year
    • Pearson correlation coefficient will be used to evaluate the relationship between mild cognitive impairment and drug used preoperatively in geriatric patients.
