stdKtV Calculator

The app estimates the treatment times required to reach a target stdKt/V calculated according to the 2015 Update of the KDOQI Clinical Practice Guidelines for Hemodialysis Adequacy. The app first requires an estimate of the urea distribution volume. A physician can either enter a urea volume obtained from the provider's monthly report or enter the patient's age, gender, weight, and height to obtain the body water volume calculated by the Watson formula. The physician next enters the current treatment time, spKt/V, Kru, estimated weekly fluid gain, and a target stdKt/V. The default target stdKt/V is 2.3 as recommended in the 2015 Update. Different values, however, can be entered. From these entered values the app calculates the treatment times required to reach the target stdKt/V if frequency is maintained at three treatments a week and if frequency is reduced to two treatments a week. The app provides an alert if the suggested treatment times would result in fluid removal rates in excess of a commonly cited maximum of 13 ml/kg/hr.

Otherwise, the user can use the physical parameters of the patient, such as age, weight, height, gender by birth, to calculate an estimated urea distribution volume to then further calculate the estimated time at which the patient should be under dialysis to achieve the target stdKt/V. Also note that the program uses body water volume and the Watson equations to get an estimate of the urea distribution volume.
