Expectations predict chronic pain treatment outcomes.

Area of Science:

• Pain Medicine
• Psychology
• Health Outcomes Research

Background:

• Patient expectations are linked to health outcomes, but their role in multidisciplinary pain programs is not well understood.
• Multidisciplinary pain programs offer comprehensive care, yet the influence of patient expectations on treatment success requires further investigation.

Purpose of the Study:

• To investigate the predictive association between patient pretreatment expectations and clinical outcomes in a large cohort of chronic pain patients.
• To determine if patient expectations influence pain intensity, quality of life, functioning, and treatment satisfaction after multidisciplinary pain treatment.

Main Methods:

• Observational cohort study of 2272 patients treated at university-affiliated multidisciplinary pain centers.
• Pretreatment expectations regarding pain relief and quality of life were measured.
• Clinical outcomes including pain intensity, depressive symptoms, and functional interference were assessed at 6-month follow-up using structural equation modeling.

Main Results:

• Significant positive relationships were found between pretreatment expectations and most clinical outcomes.
• Patient expectations mediated the association with outcomes, particularly through global impressions of change.
• These patterns held across diverse patient subgroups (sex, age, pain duration, pain classification).

Conclusions:

• Patient expectations are a crucial determinant of treatment outcomes in multimodal pain management.
• Higher positive expectations are associated with superior clinical results in chronic pain patients.
• Incorporating expectation management may enhance the effectiveness of pain treatment programs.
