Today's critically ill patients require heightened vigilance and extraordinarily intricate care. As skilled and responsible health professionals, the 403,000 critical care nurses in the United States must acquire the specialized knowledge and skills needed to provide this care and demonstrate their competence to the public, their employers, and their profession. Recognizing that nurses can validate specialty competence through certification, this white paper from the American Association of Critical-Care Nurses and the AACN Certification Corporation puts forth a call to action for all who can influence and will benefit from certified nurses' contribution to patient care.

Severe sepsis is a major public health concern and a burden on the healthcare system. Despite improvements in efforts to control the source of infection and increased recognition by healthcare providers of patients with the disease, the mortality rate remains unacceptably high, from 30% to 50%. The systemic inflammatory response syndrome criteria are used as diagnostic indicators of sepsis when they occur in patients with known or suspected infection. ⋯ In its active form, protein C has anti-inflammatory, antithrombotic, and profibrinolytic properties that can reduce organ injury associated with severe sepsis. A recombinant form of activated protein C, drotrecogin alfa (activated), significantly reduces 28-day mortality due to all causes in patients with severe sepsis and has an acceptable safety profile. This review provides an overview of severe sepsis, highlighting recent advances in treatment of the disease and the role of critical care nurses.

As costs related to mechanical ventilation increase, clear indicators of patients' readiness to be weaned are needed. Research has not yet yielded a consensus on physiological variables that are consistent correlates of weaning outcomes. Subjective perceptions rarely have been examined for their contribution to successful weaning. ⋯ Multidimensional assessment of both primary and secondary indicators of readiness to be weaned is necessary for timely, efficient weaning from mechanical ventilation. Primary assessments include physiological variables related to gas exchange, hemodynamic status, diaphragmatic expansion, and airway clearance. Secondary assessments include perceptions related to key physiological variables. Additional research is needed to determine the predictive value of physiological variables and perceptions of dyspnea, fatigue, and self-efficacy.

No data have been collected to describe the products, methods, and frequency of oral care needed to reduce dental plaque, oral colonization, and ventilator-associated pneumonia in critically ill patients. ⋯ Despite evidence that they are ineffective for plaque removal, sponge toothettes remain the primary tool for oral care, especially in intubated patients in intensive care units. Nurses report frequent oral care interventions, but few are documented. Education and focus on good oral care strategies are required; nursing research to delineate the best procedure for all patients in intensive care units is needed.
