Care bundles aim to improve standard of care and patient outcome by promoting the consistent implementation of a group of effective interventions. However, a variety of barriers prevent their full application in clinical practice. Here, we discuss some of the benefits and limitations of care bundles in the delivery of safer and more effective and consistent health care.

Climate change and environmental stewardship are phrases that have been defining the past few decades and promoting change in our societies. The sensitivities of intensive care as a specialty make the process of greening an intensive care unit a challenge, but not one that is insurmountable. ⋯ Generally, practices in critical care are accepted without questioning the environmental consequences. We believe it is time for change, and critical care should give environmental stewardship a higher priority.

The number of patients requiring prolonged mechanical ventilation (PMV) is likely to increase. Transferring patients to specialised weaning units may improve outcomes and reduce costs. The aim of this study was to establish the incidence and outcomes of PMV in a UK administrative health care region without a dedicated weaning unit, and model the potential impact of establishing a dedicated weaning unit. ⋯ One in every sixteen ventilated patients requires PMV in our region and this group use a substantial amount of health care resource. Establishing a weaning unit would potentially reduce acute bed occupancy by 8-10% and could reduce overall treatment costs. Restructuring the current configuration of critical care services to introduce weaning units should be considered if the expected increase in PMV incidence occurs.

Experiencing treatment on a modern intensive care unit (ICU) is a potentially traumatic event. People who experience traumatic events have an increased risk of depression, anxiety disorders and post-traumatic stress disorder (PTSD). ⋯ The extent to which the consequences of critical illness and the treatments received in the ICU contribute to the development of PTSD is poorly understood and more rigorous studies are needed. Understanding the factors associated with a poor psychological recovery after critical illness is essential to generate models of causality and prognosis, and to guide the delivery of effective, timely interventions.

Protocols using high levels of positive end-expiratory pressure (PEEP) in combination with low tidal volumes have been shown to reduce mortality in patients with severe acute respiratory distress syndrome (ARDS). However, the optimal method for setting PEEP is yet to be defined. It has been shown that respiratory system reactance (Xrs), measured by the forced oscillation technique (FOT) at 5 Hz, may be used to identify the minimal PEEP level required to maintain lung recruitment. The aim of the present study was to evaluate if using Xrs for setting PEEP would improve lung mechanics and reduce lung injury compared to an oxygenation-based approach. ⋯ In a lavage model of lung injury a PEEP optimization strategy based on maximizing Xrs attenuated the signs of ventilator induced lung injury. The respiratory system reactance measured by FOT could thus be an important component in a strategy for delivering protective ventilation to patients with ARDS/acute lung injury.
