[How reliable is our memory for acute postoperative pain].

Area of Science:

• Pain research
• Medical memory studies

Background:

• Clinicians rely on patient recall of pain for diagnosis and treatment assessment.
• The accuracy of retrospective pain accounts is not well understood.

Purpose of the Study:

• To assess the accuracy of patients' retrospective pain evaluations.
• To compare retrospective pain recall with objective pain intensity data.

Main Methods:

• Examined patients' retrospective pain intensity ratings from the first postoperative day.
• Compared these ratings with pain intensity data recorded in patient-controlled analgesia (PCA) reports.

Main Results:

• Patient recall of pain intensity was moderately accurate, with a tendency to overestimate.
• Overestimation of pain was linked to a lack of significant pain relief in the first three postoperative days.
• Pain intensity on day three and patient expectations influenced recall accuracy.

Conclusions:

• Real-time pain intensity recording is recommended alongside retrospective accounts.
• Pain memory, not just the experience, influences future treatment decisions, compliance, and satisfaction.
• Findings align with established memory research frameworks.
