EL DORADO Cohort: Integrated Disability Evaluation for Low Back Pain

The EL DORADO cohort dataset contains integrated multidomain disability evaluations for 542 patients with low back pain referred to the Spine Center of Southern Denmark. Anders Hansen published this proof-of-concept study on figshare in March 2026, demonstrating the feasibility of embedding a 22-minute assessment protocol into routine secondary care. The dataset integrates patient-reported outcomes, performance-based functional tests, markerless kinematic motion capture, quantitative sensory testing, and linked electronic health record data.

Use Cases

• Predicting long-term disability outcomes based on integrated patient-reported outcomes and performance-based measures.
• Identifying patient subgroups for targeted interventions using combined quantitative sensory testing and kinematic motion data.
• Modeling the relationship between electronic health record data (e.g., MRI availability) and clinical assessment scores.
• Analyzing patient retention and engagement patterns using the 60-week SMS follow-up data.

Strengths

• Multidomain data integration from 5 distinct sources (PROs, functional tests, kinematics, QST, EHR) for 542 patients.
• High data completeness reported at over 95% for the core assessment battery.
• Successful EHR linkage for all participants and 75% SMS follow-up retention at 60 weeks.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale modeling.
• The dataset is very small (30.1 KB), suggesting it may be a summary or metadata document rather than the full raw data.
