Delirium affects nearly 40% of patients undergoing elective vascular surgery. Key risk factors include advanced age, cognitive issues, and blood transfusions, highlighting potential areas for pre-operative intervention.

Area of Science:

  • Medical Research
  • Surgical Outcomes
  • Geriatric Medicine

Background:

  • Delirium is a frequent complication in surgical patients.
  • Elective vascular surgery patients face a heightened risk of delirium.
  • Identifying modifiable risk factors could inform pre-operative strategies.

Purpose of the Study:

  • To review the existing literature on the incidence of delirium in elective vascular surgery.
  • To identify the etiological factors contributing to delirium in this patient population.

Main Methods:

  • A comprehensive literature search was conducted across medical databases, journals, and bibliographies.
  • Predetermined quality criteria were applied to appraise the identified incidence and etiological studies.

Main Results:

  • Four relevant studies were included in the review.
  • The incidence of delirium ranged from 29.1% to 39.2%.
  • Significant etiological factors identified included advanced age, pre-operative cognitive impairment, depressive symptoms, intra-operative blood transfusion, and prior amputation.

Conclusions:

  • Delirium is a common occurrence in patients undergoing elective vascular surgery.
  • Further research is needed to understand the impact of delirium on patient outcomes.
  • Investigating the efficacy of psychiatric and geriatric medicine interventions in this context is recommended.
