Abstracts e IMPLEMENTATION OF EARLY GOAL-DIRECTED THERAPY FOR SEVERE SEPSIS AND SEPTIC SHOCK: A DECISION ANALYSIS. Huang DT, Clermont G, Dremsizov TT, et al. Crit Care Med 2007;35:2090 –100. This study from the University of Pittsburgh used a decision model to evaluate the clinical and economic consequences of early goal-directed therapy (EGDT) using data generated from previous human trials. The authors devised a simulation of an average United States Emergency Department (ED) and inves- tigated the potential costs and consequences of implementing EGDT in this simulated ED. There were three ways in which EGDT was simulated to begin: a) ED-based, b) mobile inten- sive care unit (ICU) team, and c) ICU-based (after ED transfer). The simulation estimated 91 annual cases of severe sepsis and septic shock with start-up costs of the implementation ranging from $12,973 (ICU based) to $26,952 (ED based), with an annual cost of $100,113 thereafter. It was estimated that EGDT reduced net hospital costs by approximately 22.9%, principally by decreasing hospital length of stay. Simulated EGDT imple- mentation was determined to have a 99.4 –99.8% probability of saving lives and reducing costs from $2749 (ICU based) to $7019 (ED based) per quality-adjusted life-year. The ICU- based treatment arm was the least expensive but also the least effective, thought secondary to a potential delay in EGDT implementation. The authors conclude that although EGDT may have significant start-up costs and not-insignificant deliv- ery costs, it is cost-saving to the hospital with decreased patient length of stay and may have favorable lifetime cost-effective- ness projections with overall decreased mortality.

Agati L, Funaro S, Madonna M, et al. Am Heart J 2007;154:151–7. This study from Italy randomized 96 consecutive patients with their first ST-segment elevation myocardial infarction, presenting within 3 h of onset of symptoms, into three treat- ment groups: primary percutaneous coronary intervention (PCI), thrombolysis followed within 24 h by PCI (thromboly- sis/PCI), and thrombolysis alone. All patients initially received aspirin and subcutaneous enoxaparin. Patients in the two PCI groups received infarct-related artery stenting with abciximab administered just before the procedure, and for 12 h afterwards, as well as a 6-month course of clopidigrel and daily aspirin indefinitely. Those in the thrombolysis groups received tenect- eplase. The primary endpoint of the study was to assess the effect of early PCI after thrombolysis on the extent of residual microvascular damage, quantified with myocardial contrast echocardiography. Left ventricular function was also assessed with two-dimensional echocardiography on hospital day 2, pre-discharge, and at 3 months. The thrombolysis-only group had a significantly higher degree of microvascular damage, larger infarct size, and poorer left ventricular function, both after treatment and on follow-up, than those in the PCI and thrombolysis/PCI groups. There was not a statistically signifi- cant difference in outcomes for the primary PCI and thrombol- ysis/PCI groups. The authors conclude that PCI within 24 h of thrombolysis is superior to thrombolysis alone, and similar to primary PCI. This information may be helpful in planning treatment for patients who present to institutions where primary PCI is not available. [Emily Johnston, MD, Denver Health Medical Center, Denver, CO] Editor’s Comment: This study confirms others previously published and suggests that thrombolysis alone is less effective than thrombolysis combined with early PCI or PCI alone at reducing infarct size. The study does not address whether this disease-oriented outcome is clinically relevant. e OUTCOME IN PATIENTS WITH SUBARACHNOID HEMORRHAGE TREATED WITH ANTIEPILEPTIC DRUGS.

Editor’s Comment: The findings of this study are dependenton the validity of its many assumptions needed to generate thesimulation. Nonetheless, the model demonstrated potential hos-pital and societal financial gains by implementing EGDT, es-pecially in the ED setting. The ED implementation of EGDT inpatients with severe sepsis and septic shock has been shown tobe effective in reducing patient mortality and also may be morecost-effective for the hospital and society overall.
