Fixes #1357

Summary

  • Replaces the hard-coded creat_low_past_48hr <= 3.7 shortcut in stage 3 creatinine logic
  • Uses KDIGO-defined acute rise checks: creat >= creat_low_past_48hr + 0.3 OR creat >= 1.5 * creat_low_past_7day when creat >= 4.0

Test plan

fix(mimic-iv): correct KDIGO stage 3 creatinine rise criteria
d274159 
Replace the hard-coded creat_low_past_48hr <= 3.7 shortcut with the
KDIGO-defined acute rise checks (>=0.3 mg/dL within 48h or >=1.5x
baseline) for patients with creatinine >= 4.0.

Fixes MIT-LCP#1357.
