Evaluating the cost-effectiveness of the ABCDE bundle: impact of bundle adherence on inpatient and 1-year mortality and costs of care.
This study examined the cost-effectiveness of the Awakening and Breathing Coordination, Delirium monitoring/management, and Early exercise/mobility (ABCDE) bundle intervention to improve short- and long-term clinical outcomes for patients requiring ICU care. A 2-year, prospective, cost-effectiveness study in 12 adult ICUs in six hospitals belonging to a large, integrated healthcare delivery system was conducted. Hospitals in the study included a large, urban center and five community hospitals. ICU types included medical/surgical, trauma, neurologic, and cardiac care units. The cohort included 2,953 adults with an ICU stay greater than 24 hours who were on a ventilator for more than 24 hours and less than 14 days. ICUs with high ABCDE bundle adherence significantly decreased odds of inpatient mortality and had significantly higher costs of inpatient care. The incremental cost-effectiveness ratio of high bundle adherence was $15,077 per life saved, and $1,057 per life-year saved.

Utilization of intensive care unit nutrition consultation is associated with reduced mortality.
The aim of this project was to investigate the prevalence of nutrition consultation (NC) in U.S. intensive care units (ICUs) and to examine its association with patient outcomes. Data from the Healthcare Cost and Utilization Project's state inpatient databases was utilized from 2010 - 2014. A multilevel logistic regression model was used to evaluate the relationship between NC and clinical outcomes. The investigators concluded that rates of NC were low in critically ill patients.

Mortality among older adults before versus after hospital transition to intensivist staffing.
The researchers sought to determine whether hospitals can reduce their mortality by adopting an intensivist staffing model. Adoption of an intensivist staffing model was not associated with improved mortality in Medicare beneficiaries. These findings suggest that the lower mortality rates previously observed at hospitals with intensivist staffing may be attributable to other factors.
