BNP Therapy Observation Unit Outcomes STudy (BOOST)

Congestive heart failure (CHF) is a growing problem in the United States. The increasing number of decompensated heart failure patients presenting to emergency departments (ED) for treatment is worsening the burden on already strained and limited health care resources. In addition, many of these patients will return to the ED for treatment within three months of being treated for decompensated heart failure. The emergence of ED observation units has provided a viable and cost effective alternative to inpatient treatment for many diseases including CHF. It has been shown that intensive, directed therapy in ED observation units has decreased the revisit rates for CHF patients. In addition, the introduction of nesiritide has shown promising results in the treatment of decompensated congestive heart failure.

The primary aim of this study is to compare nesiritide versus standard heart failure therapy in an ED setting. A secondary aim is to determine if serial BNP levels during this observation unit stay will predict clinical outcomes.

The treatment of heart failure in the ED places a tremendous burden on already limited resources. The costs of treatment as well as the morbidity and mortality associated with the disease are worsening and are predicted to increase as the general population ages. The ability to safely treat and discharge patients from an ED observation unit while reducing return visits would be invaluable in managing the growing number of heart failure patients.
