Impact of nesiritide on health care resource utilization and complications in patients with decompensated heart failure

Study Objective. To determine the impact of nesiritide on health care resource utilization and complications in patients hospitalized with decompensated heart failure. Design. Retrospective case-control study. Setting. United States hospitals. Patients. Two hundred sixteen patients hospitalized for decompensated heart failure. Measurements and Main Results. One hundred eight patients who received a nesiritide infusion for a minimum of 12 hours during the first 48 hours after hospital admission were matched with 108 patients not receiving nesiritide. Health care resource utilization, consisting of hospital length of stay (LOS), rate of rehospitalization within 90 days, concomitant drugs administered, and laboratory and diagnostic tests, was determined for each hospital admission. Rates of adverse events also were recorded. Patients receiving nesiritide had a significantly shorter LOS in a critical care unit (p=0.03). General medical ward or step-down unit LOS was not different between the treatment groups. A favorable trend toward a lower rate of rehospitalization over the 90-day follow-up period was observed with nesiritide (p=0.07). The number of patients who developed life-threatening ventricular arrhythmias and hypotension was similar for both treatment groups. However, in patients receiving nesiritide, significantly less atrial fibrillation (p=0.03) and renal dysfunction (p=0.04) occurred compared with patients not receiving nesiritide. Conclusion. Nesiritide therapy is associated with significant reductions in both health care resource utilization and complications in patients with decompensated heart failure.
