Changes in nursing team composition and risk of device-associated infection in intensive care units.

The relationship between nursing staffing levels and healthcare-associated infections (HAIs) has been explored previously with conflicting results. This study uses daily shift records from 2 intensive care units (ICUs) to evaluate whether nuanced changes in nursing team composition impacts subsequent risk for device associated HAIs. Staffing deficiencies may be associated with periods of risk prior to central line-associated bloodstream infection in the ICU.

Turning and repositioning the critically ill patient with hemodynamic instability: a literature review and consensus recommendations.

In the critical care population, heart rate and rhythm, blood pressure, respiratory rate, and oxygen saturation are monitored continuously, providing immediate feedback regarding any changes in patient status. Hemodynamic instability is a term commonly used by clinicians to describe labile changes in cardiopulmonary status, although this term is poorly defined in the literature. The clinician's perception of hemodynamic instability may cause a delay or omission in turning, repositioning, and other interventions to advance patient mobility and may contribute to pressure ulcer formation. The intensive care unit's practice culture and individual clinician perceptions regarding hemodynamic instability may lead to staff not turning patients out of fear that they are "too unstable to turn." This article provides a discussion of the link between pressure ulcers and immobility, provides a review of current literature on progressive mobility and hemodynamic instability, and presents the results of a critical care consensus panel on safe and effective turning of critical care patients.
