baseline-creatinine
Estimate baseline serum creatinine for AKI assessment in MIMIC-IV. Use for KDIGO staging, AKI research, or renal function baseline establishment.

Same command for any agent — swap --agent for codex, cursor, copilot.

# Baseline Creatinine Estimation Estimates the patient's baseline (pre-illness) serum creatinine, which is critical for accurate AKI staging. The true baseline is often unknown; this query uses a hierarchical approach. ## When to Use This Skill - KDIGO AKI staging (requires baseline comparison) - AKI research cohorts - Chronic kidney disease identification - Renal function trajectory analysis ## Baseline Determination Rules The baseline creatinine is determined hierarchically: 1. **If lowest admission creatinine <= 1.1 mg/dL**: Use the lowest value (assumed normal) 2. **If patient has CKD diagnosis**: Use the lowest admission value (even if elevated) 3. **Otherwise**: Estimate baseline using MDRD equation assuming GFR = 75 mL/min/1.73m^2 ## Pre-computed Table ```sql SELECT hadm_id, gender, age, scr_min, -- Lowest creatinine during admission ckd, -- 1 if CKD diagnosis present mdrd_est, -- Estimated creatinine from MDRD scr_baseline -- Final baseline determination FROM mimiciv_derived.creatinine_baseline; ``` ## MDRD Estimation Formula For patients without normal creatinine and without CKD, baseline is estimated: **Male patients:** ``` scr_baseline = (75 / 186 / age^(-0.203))^(-1/1.1

What does the baseline-creatinine skill do?
Estimate baseline serum creatinine for AKI assessment in MIMIC-IV. Use for KDIGO staging, AKI research, or renal function baseline establishment.
How do I install it?
Run `npx skills add majiayu000/claude-skill-registry --skill baseline-creatinine --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From majiayu000/claude-skill-registry, a repository with 534 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
