Abstract

Recently, our institution adopted a weight-based nurse-driven heparin titration protocol that relies on nurses ordering laboratories, adjusting doses, and initiating boluses. Numerous institutions have implemented similar protocols with reported success. A single-center retrospective analysis was conducted at the Brigham and Women's Hospital in Boston, Massachusetts that included all patients who were initiated on the weight-based nurse-driven heparin nomogram during a 30-day period. Nomogram compliance was defined as the rate of correct titrations per nomogram encounter and further separated into laboratory, titration, or dosing compliance. Spearman's coefficient was utilized to determine the correlation between noncompliance and percentage of activated partial thromboplastin time (aPTT) values in range. Overall, 211 patients were evaluated for inclusion, of which 95 patients were determined to meet criteria for evaluation. The total nomogram compliance rate was 84.6% ± 10.5%. Laboratory, titration, and dosing compliances were 77.6% ± 19.2%, 87.2% ± 14.5%, and 91.8% ± 10.6%, respectively. The percent of aPTT values in therapeutic range was 39.6% ± 24.6%. A moderate negative correlation between the percentage of aPTT values in ...Continue Reading

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.
