baseline-creatinine

Estimate baseline creatinine by applying a hierarchical rule set that uses the lowest in-hospital creatinine when CKD is present, or MDRD-based estimation otherwise, ensuring consistent comparisons across patients.

Determining baseline creatinine for CKD identification uses a hierarchical approach applying admission creatinine, CKD status, and MDRD-based estimation to provide a defensible, reproducible baseline per admission.

Compute baseline creatinine for KDIGO staging by running the provided SQL baseline query, which calculates scr_baseline for patient admissions based on a hierarchical clinical rule set.

Use MDRD-based estimation for renal function trajectory research when a patient's baseline creatinine is unknown at admission and CKD status does not indicate using the lowest in-hospital value.

Yes, the baseline creatinine approach works for diverse clinical research datasets by enforcing a hierarchical rule set that provides reproducible baseline values across varied adult inpatient populations.

Use a hierarchical rule set for baseline creatinine because baseline is often unknown at admission, requiring fallback logic between admission creatinine, CKD flags, and MDRD estimation for defensible AKI staging.
