The mean time to appropriate antimicrobial therapy was 23.4 h longer in the preintervention group than in the postintervention group (P ‫؍‬ 0.0054). A nonsignificant decrease in the mean time to appropriate antimicrobial therapy was seen for patients infected with vancomycin-susceptible Enterococcus isolates (P ‫؍‬ 0.1145). For patients with vancomycin-resistant Enterococcus bacteremia, the mean time to appropriate antimicrobial therapy was 31.1 h longer in the preintervention group than in the postintervention group (P < 0.0001). In the postintervention group, the hospital length of stay was significantly 21.7 days shorter (P ‫؍‬ 0.0484) and mean hospital costs were $60,729 lower (P ‫؍‬ 0.02) than in the preintervention group. The rates of attributed deaths in the two groups were not statistically different. Microarray technology, supported by pharmacy and microbiology departments, can decrease the time to appropriate antimicrobial therapy, the hospital length of stay, and health care costs.

Acute respiratory distress syndrome (ARDS) is a syndrome of acute lung injury that is characterized by noncardiogenic pulmonary edema and severe hypoxemia second to a pathogenic impairment of gas exchange. Despite significant advances in the area, mortality remains high among ARDS patients. High mortality and a limited spectrum of therapeutic options have left clinicians searching for alternatives, spiking interest in selective pulmonary vasodilators (SPVs). Despite the lack of robust evidence, SPVs are commonly employed for their therapeutic role in improving oxygenation in patients who have developed refractory hypoxemia in ARDS. While inhaled epoprostenol (iEPO) also impacts arterial oxygenation by decreasing ventilation-perfusion (V/Q) mismatching and pulmonary shunt flow, this effect is not different from inhaled nitric oxide (iNO). The most effective and safest dose for yielding a clinically significant increase in PaO 2 and reduction in pulmonary artery pressure (PAP) appears to be 20-30 ng/kg/min in adults and 30 ng/kg/min in pediatric patients. iEPO appears to have a ceiling effect above these doses in which no additional benefit may be derived. iNO and iEPO have shown similar efficacy profiles; however, they differ with respect to cost and ease of therapeutic administration. The most beneficial effects of iEPO have been seen in adult patients with secondary ARDS as compared with primary ARDS, most likely due to the difference in etiology of the two disease states, and in patients suffering from baseline right ventricular heart failure. Although iEPO has demonstrated improvements in hemodynamic parameters and oxygenation in ARDS patients, due to the limited number of randomized clinical trials and the lack of studies investigating mortality, the use of iEPO cannot be recommended as standard of care in ARDS. iEPO should be reserved for those refractory to traditional therapies.

Purpose Sepsis can lead to poor outcomes when treatment is delayed or inadequate. The purpose of this study was to evaluate outcomes after initiation of a hospital-wide sepsis alert program. Materials and methods Retrospective review of patients ≥18 years treated for sepsis. Results There were 3917 sepsis admissions: 1929 admissions before, and 1988 in the after phase. Mean age (57.3 vs. 57.1, p = 0.94) and Charlson Comorbidity Scores (2.52 vs. 2.47, p = 0.35) were similar between groups. Multivariable analyses identified significant reductions in the after phase for odds of death (OR 0.62, 95% CI 0.39–0.99, p = 0.046), mean intensive care unit LOS (2.12 days before, 95%CI 1.97, 2.34; 1.95 days after, 95%CI 1.75, 2.06; p < 0.001), mean overall hospital LOS (11.7 days before, 95% CI 10.9, 12.7 days; 9.9 days after, 95% CI 9.3, 10.6 days, p < 0.001), odds of mechanical ventilation use (OR 0.62, 95% CI 0.39, 0.99, p = 0.007), and total charges with a savings of $7159 per sepsis admission (p = 0.036). There was no reduction in vasopressor use (OR 0.89, 95% CI 0.75, 0.1.06, p = 0.18). Conclusion A hospital-wide program utilizing electronic recognition and RRT intervention resulted in improved outcomes in patients with sepsis.
