Computational tool for the estimation of prothrombin time
Abstract
Introduction: the calculation of the international normalized relation allows to estimate the prothrombin time as a control method of anticoagulant therapy.
Objective: to develop a computational tool for the estimation of prothrombin time according to the international normalized relation.
Method: the Microsoft Office Excel 2007 program was used as a computer language, with a results-oriented user interface for easily analyzing, sharing and managing data.
Results: the computer system solved a potential-type function that estimated the international normalized relation based on the prothrombin time of the patient, the standard prothrombin time and the international sensitivity index of the thromboplastin used. It was applied at the Hospital "Dr. Antonio Luaces Iraola" of Ciego de Ávila, at the Hospital "Roberto Rodríguez Fernández" of Morón and at the Hospital "Manuel Ascunce Domenech" of Camagüey.
Conclusions: the proposed computational tool allows the calculation of the normalized international relation to be carried out quickly and easily without the need to use equipment such as the STA line analyzers based on the use of STA®-Neoplastine® CI Plus kits containing reagents to determine the prothrombin time in plasma. In the clinical laboratories in which it was used, it was able to optimize and facilitate the workDownloads
