Spreadsheet use to calculate creatinine clearance from serum creatinine

Area of Science:

• Nephrology
• Cardiovascular Surgery
• Medical Informatics

Background:

• Serum creatinine is an insufficient indicator of renal function.
• Creatinine clearance (CrCl) offers a more precise assessment of kidney function.
• Perioperative risk assessment and management strategies require accurate renal function data.

Purpose of the Study:

• To demonstrate the utility of spreadsheets for calculating glomerular filtration rate (GFR) using the Cockcroft-Gault Formula (CGF).
• To highlight the benefits of CrCl over serum creatinine for perioperative risk assessment.
• To explore the potential of spreadsheet implementation for clinical perfusion management.

Main Methods:

• Development of spreadsheets incorporating the Cockcroft-Gault Formula (CGF).
• Utilizing serum creatinine, age, weight, and sex as inputs for the CGF calculation.
• Employing logical test functions within spreadsheets for accurate CrCl computation.

Main Results:

• Spreadsheets can accurately calculate creatinine clearance (CrCl) using the CGF.
• CrCl provides a superior method for perioperative renal function assessment compared to serum creatinine.
• Spreadsheet implementation facilitates consistent and accurate clinical perfusion management.

Conclusions:

• Spreadsheets offer a practical tool for estimating GFR via the CGF.
• Accurate CrCl estimation is crucial for optimizing renal protective strategies during cardiopulmonary bypass.
• Spreadsheet-based calculations enhance the consistency and accuracy of clinical perfusion management.
