The clinical standard for benchmarking and improving patient outcomes

Access trusted, risk-adjusted benchmarks across mortality, length of stay, cost, readmissions, complications, and care variation — so teams understand their performance, identify gaps, and focus improvement efforts with confidence.

Why Clinical Data Base?

For more than 40 years, Vizient's Clinical Data Base (CDB) has equipped healthcare leaders with the clinical quality intelligence needed to act with confidence. Transparent, risk-adjusted data across mortality, length of stay, cost, and readmissions — benchmarked against relevant peer organizations — helps organizations reduce unwarranted variation, close performance gaps, and sustain improvement over time.
