Perioperative Impact of Frailty and Cognitive Impairment in Older Surgical Patients

Strategic Insights

— 1 min read

Older surgical patients with cognitive impairment (CI) and frailty are at a higher risk of experiencing worse perioperative outcomes, including longer hospital stays and a greater incidence of non-home discharge. A recent multicentered longitudinal cohort study conducted at the University of Toronto found that patients with preoperative CI were more frail at all postoperative time points than those without CI. The study, published in the Journal of Clinical Anesthesia, aimed to investigate the impact of preoperative frailty and CI on patient-reported outcomes and clinical outcomes in older non-cardiac surgical patients.

Key Takeaways:

  • Preoperative frailty and CI are prevalent conditions in older surgical patients, affecting up to 63% of patients, with CI present in 81% of patients.
  • Patients with preoperative CI were more frail at all postoperative time points than those without CI.
  • Patients classified as prefrail/frail preoperatively had longer length of stay, greater incidence of non-home discharge, and composite outcomes at 30 days than robust patients.
  • Patients with combined prefrailty/frailty and CI experienced significantly worse 90-day composite outcomes than those with prefrailty/frailty alone.
  • Female gender, orthopedic surgery, significant preoperative functional disability, and high risk of obstructive sleep apnea were significantly associated with preoperative frailty.

Statistics:

  • Up to 63% of older surgical patients experienced preoperative prefrailty (48%) or frailty (15%).
  • 81% of patients with preoperative CI were preoperatively prefrail (49%) or frail (32%).
  • Patients with preoperative CI were more frail at all postoperative time points than those without CI.
  • 30-day composite outcomes were worse in patients with preoperative frailty (20%) compared to robust patients (<5%).
  • 90-day composite outcomes were significantly worse in patients with combined prefrailty/frailty and CI (30%) compared to those with prefrailty/frailty alone (10%).
