Which patients improve: characteristics increasing sensitivity to a supportive patient-practitioner relationship

Area of Science:

• Psychosomatic Medicine
• Clinical Trial Methodology
• Genomics and Bioinformatics Applications in Health Research

Background:

• Supportive social relationships, particularly the patient-practitioner dynamic, are linked to positive health outcomes.
• Previous research demonstrated that a supportive patient-practitioner relationship significantly improved symptomatology and quality of life in Irritable Bowel Syndrome (IBS) patients.

Purpose of the Study:

• To identify baseline factors predicting patient response to an experimentally applied supportive patient-practitioner relationship within a randomized controlled trial (RCT).
• To apply a novel false discovery rate method, adapted from genomics, to analyze a large number of baseline variables in clinical trial data.

Main Methods:

• Utilized data from a three-week, single-blind, three-arm RCT involving 289 individuals with IBS.
• Employed a local false discovery rate procedure to examine associations between 452 baseline subject variables and sensitivity to the supportive patient-practitioner relationship.
• Collected data using a multi-level measurement package to prospectively assess change and identify factors associated with improvement.

Main Results:

• Only two baseline factors, reclusiveness and previous trial experience, significantly increased sensitivity to the supportive patient-practitioner relationship.
• Experiential interviews, offering additional discussion opportunities, were associated with improved outcomes for patients not receiving the supportive relationship.
• A supportive patient-practitioner relationship appears broadly beneficial, particularly for reclusive individuals and those with prior trial experience.

Conclusions:

• Patient-centered supportive relationships are likely beneficial for most patients, especially reclusive individuals.
• Additional study attention, like repeated interviews, can compensate for a lack of supportive patient-practitioner interaction.
• Supportive relationships may help overcome low provider expectations in patients with previous trial experience, highlighting the social world's importance in healing.
