Hypothesis

How accurate are self-reported case numbers in hospital quality reports?

Conclusion

The study found that a significant percentage of reported MCR caseloads were ambiguous, and many were corrected, indicating issues with data quality.

Supporting Evidence

  • 11.8–27.7% of MCR caseload values were ambiguous.
  • 7.9–23.7% of reported values were corrected.
  • 0.7–3.7% of cases not previously stated were added.
  • 1.5–26.1% of hospital sites were identified as MCR performing hospitals after correction.

Takeaway

This study checked if hospitals in Germany reported their patient numbers correctly, and found many mistakes that needed fixing.

Methodology

The study used internal cross-field validation to compare reported MCR caseloads with other variables in the German Hospital Quality Reports.

Potential Biases

Potential underreporting by hospitals with low case numbers may bias the results.

Limitations

The validation is limited by data protection regulations and the comparability of counting methods.

Participant Demographics

The study analyzed data from all hospitals in Germany reporting MCR compliance.
