Do patient and physician expectations predict response to pain-relieving procedures?

Area of Science:

• Pain management research
• Clinical psychology
• Medical decision-making

Background:

• Patient expectations can influence treatment outcomes.
• The role of physician expectations in chronic pain management is less understood.

Purpose of the Study:

• To investigate the relationship between patient and physician pretreatment expectations of pain relief and actual pain relief in chronic pain patients.
• To determine who is a better predictor of treatment success: patient or physician expectations.

Main Methods:

• Prospective study involving 46 chronic pain patients undergoing procedures like nerve blocks or IV infusions.
• Patients and physicians independently rated expected pain relief before procedures.
• Pain levels and pain relief were assessed post-procedure.

Main Results:

• Patient pretreatment expectations did not significantly correlate with post-procedure pain relief.
• Physician expectations of pain relief showed a significant correlation with patient-reported pain relief and improvement.
• Physician predictions were stronger indicators of patient outcomes than patient self-predictions.

Conclusions:

• Physicians may be more accurate predictors of patient response to pain treatments than patients themselves.
• Physician expectations might subtly influence patient outcomes, potentially through communication or by affecting nonspecific treatment effects.
• Patient pretreatment expectations may not be the primary driver of nonspecific effects in certain pain interventions.
