EQ-5D-5L Pain Assessment in Colorectal Cancer Surgery Patients, 2023-2025

A retrospective analysis of prospectively collected data from 333 adult patients undergoing elective minimally invasive colorectal cancer surgery at a single tertiary center between October 2023 and December 2025. The dataset, authored by Sooah Cho and hosted on Harvard Dataverse, examines the validity of the EQ-5D-5L pain/discomfort dimension for acute postoperative pain assessment against numeric rating scales.

Use Cases

• Validate the EQ-5D-5L pain/discomfort dimension against numeric rating scale scores based on correlations mentioned in the description.
• Assess the discriminative ability of a health-related quality of life instrument for postoperative pain based on the analysis of adjacent level discrimination.
• Compare pain outcomes between Enhanced Recovery After Surgery and conventional care groups using the cumulative link mixed models described.
• Evaluate the responsiveness of a pain assessment tool based on standardized response means calculated in the study.

Strengths

• Includes data from 333 patients, providing a substantial sample size for analysis.
• Covers postoperative days 1–3 with pain assessments at rest and during coughing, offering a multi-day perspective.
• Demonstrates moderate correlations (ρ = 0.44–0.57) between the EQ-5D-5L dimension and numeric rating scales, providing quantitative validity evidence.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a single tertiary center, which may limit generalizability to other surgical populations.
