Estimated Creatinine Clearance: Enhance Cockcroft-Gault calculation with IDMS conversion

This is an ask for an enhancement of the Cockcroft-Gault calculation for estimated creatine clearance when site lab uses IDMS methodology for serum creatinine for patient.

Current formula: [ (140-age) * Wt ] / ( SCr * 72 )

Conversion to Conventional: SCr (mg/dL) = ( IDMSSCr ) ∗ 1.065 + 0.067

Final formula: [ ( 140-age ) * Wt ] / [ ( IDMSSCr * 1.065 + 0.067 ) * 72 ]
