A computerized database for haemophilia patient records.

A microcomputer database system for the storage, retrieval, and statistical analysis of data associated with the treatment of haemophilia and other defects of haemostasis is described. The hardware requirements are an IBM compatible PC with both hard and floppy disc drives and a suitable printer. The system was written using Smartware II, a powerful integrated software package which incorporates database, word processor, spreadsheet and communications functions.

Comparison of liquid and dried sodium citrate as the anticoagulant for Thrombotest and prothrombin time estimations.

Samples which are taken for the Quick one-stage prothrombin time estimation for the control of patients receiving oral anticoagulant treatment are by convention taken into liquid sodium citrate anticoagulant. Dried sodium citrate has been rejected on the grounds that excessive haemolysis causes activation of clotting factors and therefore falsely short clotting times. Tests were performed with both liquid and dried sodium citrate as an anticoagulant for prothrombin time and Thrombotest.
