Colorectal Cancer Screening Trial Data from Switzerland (2018-2021)

2,112 patient records from a pragmatic randomized controlled trial in Switzerland (2018–2021) testing a primary care physician intervention to increase colorectal cancer screening rates. The dataset, authored by Tamara Scharf and shared under a CC-BY-4.0 license, includes results from 63 physicians across nine quality circles, showing a significant increase in screening rates.

Use Cases

• Analyzing the impact of physician training and feedback on screening rates based on the described intervention.
• Modeling patient-level screening outcomes based on the trial's demographic data (e.g., mean age 61.5, 53% women).
• Studying cluster effects in healthcare interventions based on data grouped by physician and quality circle.
• Evaluating pragmatic trial design and participation rates based on the described recruitment of 9 out of 120 invited circles.

Strengths

• Includes 2,112 patient records with demographic details (mean age 61.5, 53% women).
• Data is from a pragmatic randomized controlled trial with a clear methodology described.
• Results are statistically significant, showing a screening rate increase from 55% to 57.9% in the intervention group.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the underlying data tables is unknown, which may limit suitability assessment.
• The trial had limited participation, with only 9 out of 120 invited quality circles taking part.
