In the health care community, nurses are important agents of change and vehicles for improvements in clinical practice and policy. Pediatric nurses empowered with the tools of evidence-based practice and clinical expertise collaborated in 2007 with other health care professionals to make changes in clinical practice for pediatric patients with vascular access devices (VADs). Nurses recognized that there was a need for a change in the heparinization policy for children with short- and long-term VADs. Data were methodically collected over a 1-year period on 500 VAD. Data collection demonstrated a range of VAD volumes that did not exceed 2 mL. The group analysis of the results gave support for changes in the volumes needed for heparinization. Establishment of appropriate heparin dosing based on scientific data led to a decrease in heparin used to maintain pediatric VAD patency and aided in lowering the risk of side effects in patients.

To understand differences in anti-factor-Xa levels produced by two different dosing strategies (conventional and individualized) for therapeutic enoxaparin in a cohort of hospital inpatients. A multicenter, retrospective cohort study over a two- and a half-year period for inpatients with stable renal function and on therapeutic enoxaparin. Anti-factor-Xa levels were taken 3-5 h after enoxaparin administration and a minimum of 48 h of dosing.

The role of heparin in sepsis therapy has been widely debated. The controversy surrounding heparin's use as an anticoagulant in sepsis may stem from differences in sepsis definitions, study designs, timing and dosage of drug administration, treatment duration, complications, and patient severity. In this study, we aimed to determine the optimal timing and dosage of heparin in patients with sepsis, identify specific subgroups that could benefit from heparin therapy, and explore laboratory markers to assess its efficacy.

Background: A minimum threshold activated clotting time (ACT) to guide heparin dosing during percutaneous coronary intervention (PCI) is associated with lower ischemic complications. However, data are variable regarding the risk of high ACT levels. The aim of this study was to assess the impact of peak procedural ACT on complications and mortality for transfemoral and transradial access PCI.
