Using the balanced scorecard to measure outcomes, a multidisciplinary team worked to improve antiemetic therapy and decrease postoperative nausea and vomiting. Patient satisfaction measures were nausea and pain scales (10 cm, nonnumbered, visual analog). The quality measure was number of vomiting episodes. ⋯ There were no deteriorations in pain scores or length of stay. Balanced scorecard measurements suggest no adverse unintended outcomes consequent to changes in prescribing behavior. Balanced scorecard processes assisted consensus among pharmacists, nurses, and physicians that may have accelerated behavioral changes.

To identify and describe the scope of practice that characterizes the critical care pharmacist and critical care pharmacy services. Specifically, the goals were to define the level of clinical practice and specialized skills characterizing the critical care pharmacist as clinician, educator, researcher, and manager; and to recommend fundamental, desirable, and optimal pharmacy services and personnel requirements for the provision of pharmaceutical care to critically ill patients. Hospitals having comprehensive resources as well as those with more limited resources were considered. ⋯ By combining the strengths and expertise of critical care pharmacy specialists with existing supporting literature, these recommendations define the level of clinical practice and specialized skills that characterize the critical care pharmacist as clinician, educator, researcher, and administrator. This position paper recommends fundamental, desirable, and optimal pharmacy services as well as personnel requirements for the provision of pharmaceutical care to critically ill patients.

Review Case Reports
Phytonadione therapy in a multiple-drug overdose involving warfarin.
We cared for a patient who ingested an unknown amount of acetaminophen with zopiclone and warfarin. The only liver function test that was abnormal was an increased international normalized ratio (INR), which remained elevated despite treatment with subcutaneous phytonadione and a prolonged infusion of N-acetylcysteine. ⋯ The patient received numerous antibiotics that may have contributed to the increased INR. The prolonged elevation of INR also may have been due to infrequent administration of phytonadione.

Randomized Controlled Trial Clinical Trial
Randomized, placebo-controlled trial of oral phytonadione for excessive anticoagulation.
To compare the efficacy of managing excessive anticoagulation in the absence of bleeding by either omitting warfarin therapy alone or administering oral phytonadione in addition to omitting warfarin therapy. ⋯ The addition of oral phytonadione 2.5 mg reduced the time to achieve an INR of 4.0 by approximately 1 day compared with omitting warfarin therapy alone. Adverse events did not differ between the two groups. Both strategies were effective in managing asymptomatic patients with INRs of 6.0-10.0. Oral phytonadione may be most appropriate for patients at high risk for bleeding in whom the benefit of prompt INR reduction would outweigh the thromboembolic risk associated with INR overcorrection.

Review
Hemodynamic and cardiovascular effects of nitric oxide modulation in the therapy of septic shock.
Nitric oxide synthase (NOS) of the inducible subtype (iNOS) plays a pivotal role in vasodilation associated with sepsis. Various biochemical pathways are involved, revealing targets for inhibiting the consequence of iNOS activation. Interactions of transcription factors, inducers, cofactors, and regulators of iNOS are important in understanding the development of iNOS inhibitors. ⋯ It is anticipated that iNOS-specific compounds will be clinically useful. The focus of future human trials will be on these agents. Although ideal therapy for treating vasodilation from sepsis is not available, research into the pathophysiology of NOS in sepsis clarified the complexities surrounding this therapeutic dilemma.
