We greatly enjoyed reading the article by Kershaw and colleagues,¹ as well as the study by Elliot et al,² each describing successful methods of standardizing heparin therapy in the treatment of deep venous thrombosis. Kershaw and colleagues¹ expressed interest in a success rate analysis from our study³ on the weight-based heparin nomogram that appeared in a tabular form in our original article.

From among 62 patients randomized to treatment with the weight-based nomogram, 444 activated partial thromboplastin time (aPTT) values were obtained within 48 hours of initiation of heparin therapy. We found that 17% (77/444) of our aPTTs were subtherapeutic, 65% (288/444) were therapeutic, and 18% (79/444) were supratherapeutic. Thus, our nomogram was identically successful to computer-assisted dosing in maintaining aPTT values above the therapeutic threshold (83% of the time). We were slightly less successful in avoiding supratherapeutic aPTTs, however our definition of therapeutic range (an . . . [Full Text PDF of this Article]
