Key result
Mild cognitive impairment is linked to reduced postoperative pain, while disability and frailty show no effect.
Why the study?
Postoperative pain is linked to complications, motivating an exploration of potential age-related risk factors for acute postoperative pain in older surgical patients.
Do preoperative disability, cognitive impairment, frailty, and opioid use affect acute postoperative pain in older patients undergoing surgery?
Population
155 patients ≥65 years undergoing elective surgery
Comparison
Patients with vs without disability, mild cognitive impairment, frailty, and preoperative opioid use

Do preoperative disability, cognitive impairment, frailty, and opioid use affect acute postoperative pain in older patients undergoing surgery?
In older patients undergoing surgery, preoperative mild cognitive impairment is associated with reduced reported postoperative pain, while preoperative opioid use is associated with increased pain, suggesting a need to simplify pain assessment in cognitively impaired patients.
Admiraal et al. (2023) conducted a cohort in Acute postoperative pain in older patients undergoing surgery (n=155). Preoperative disability, cognitive impairment, frailty, and opioid use vs. Absence of these risk factors was evaluated on Postoperative pain (numeric rating scale score) on the first postoperative day. Preoperative disability and frailty did not affect acute postoperative pain, whereas mild cognitive impairment was associated with reduced pain on the first postoperative day (P=0.01).
