A pocket calculator program for prediction of warfarin maintenance dose.
A 398 step program, written for the TI59 programmable calculator, has been presented. The procedure allows the user to estimate a patient's maintenance warfarin dose requirements after administration of three 10 mg doses or after any series of doses which produces a PT value greater than or equal to 20. The equation used, although based on published literature data, require further evaluation to adequately assess their clinical accuracy. They may, however, provide a starting point for maintenance dose treatment after initial therapy.
