baseline-creatinine

What problem does it solve?

Baseline creatinine is often unknown at admission, complicating AKI staging and renal-function research. This Skill provides a defensible baseline by applying a hierarchical approach that uses the lowest in-hospital creatinine when CKD is present, or MDRD-based estimation otherwise, ensuring consistent comparisons across patients.

Core Features & Use Cases

• Hierarchical baseline determination using admission creatinine, CKD status, and MDRD-based estimation.
• Reproducible baseline value per admission with clear CKD consideration.
• Provides SQL-based baseline query and documentation for research cohorts.

Quick Start

Run the provided SQL baseline query to compute scr_baseline for a patient admission.
