CardiologyCardiac surgeryNephrologyBeta toolThis tool is in beta. It has undergone internal validation but still requires additional testing. Always confirm the data entered and the results obtained before clinical use. It should not be used as the sole basis for clinical decisions.
Female sex
Congestive heart failure
Left ventricular ejection fraction below 35%
Preoperative intra-aortic balloon pump
Chronic obstructive pulmonary disease
Insulin-requiring diabetes
Previous cardiac surgery
Emergency surgery
Use exactly one of the four reviewed surgery categories.
Use mg/dL. Creatinine from 1.2 to <2.1 mg/dL adds 2 points; >=2.1 mg/dL adds 5 points.
mg/dL

Clinical noticeEducational preoperative tool only. Interpret as dialysis-risk stratification after cardiac surgery, not as a diagnosis of postoperative AKI.

Context and use

Thakar score = female sex (1) + congestive heart failure (1) + LVEF <35% (1) + preoperative IABP (2) + COPD (1) + insulin-requiring diabetes (1) + previous cardiac surgery (1) + emergency surgery (2) + surgery-type points + creatinine points

Surgery type: CABG only 0, valve only 1, CABG + valve 2, other cardiac surgery 2.

Preoperative creatinine <1.2 mg/dL = 0 points; 1.2 to <2.1 mg/dL = 2 points; >=2.1 mg/dL = 5 points.
