New Study Demonstrates Significant Economic and Clinical Value of NT-proBNP Testing for the Management of Heart FailurePaper Published in Circulation Shows Improved Management of Patients Through Better Diagnosis, Treatment Efficiency and Lower Medical Costs
ROTKREUZ, Switzerland, June 19 (HSMN NewsFeed) -- A study published today in Circulation demonstrates the effective use of NT-proBNP, Roche Diagnostics' breakthrough marker for suspected heart failure (HF), for use in both point of care and laboratory testing. The multi-center, randomized-controlled trial conducted on 500 patients in seven hospitals, shows that NT-proBNP (N-terminal proB-type natriuretic peptide) guided strategy in the management of suspected acute HF in the emergency department (ED) reduced the duration of emergency department (ED) visits by 21 percent (6.3 to 5.6 hours, p =0.031), numbers of patients re-hospitalized over 60 days by 35 percent (51 to 33, p=0.046) and direct medical costs of all ED visits, hospitalisations and subsequent outpatient services by 15 percent (USD6,129 to USD5,180 per patient, p=0.023) over 60 days from enrolment. With the total annual cost of managing HF estimated to be between USD1.4 and USD2.3 billion(1),(2), this can be calculated as potential annual savings to the Canadian healthcare system of between USD210 and USD345million.
Dr. Gordon W. Moe, a cardiologist and director of the heart failure programme and biomarker laboratory at St. Michael's Hospital in Toronto, Canada who chaired the study stated: "In a universal-access publicly-funded healthcare system like we have in Canada, we have to mandate judicious resource allocation. An approach using NT-proBNP in conjunction with clinical assessment improves the overall management of patients presenting to the emergency department with suspected acute HF through the facilitation of diagnosis, and provides health cost savings that are accompanied by an improvement in selected clinical outcomes. The use of the NT-proBNP test will improve the overall management of patients with suspected acute HF, and this biomarker should be part of the routine management of these patients."
About the Study
The multi-centre, randomised-controlled trial was conducted in 500 patients who arrived at the hospitals' emergency with shortness of breath, a classic symptom of HF. Shortness of breath is also a common symptom of other conditions such as worsening chronic obstructive pulmonary (lung) disease, pneumonia and some heart attacks, forcing emergency physicians to spend a significant amount of time trying to reach a diagnosis. NT-proBNP facilitates differentiation of those conditions.
In this study, physicians immediately committed to a diagnosis for each patient based on their clinical judgment. Those diagnoses were later judged by cardiologists blinded to each patient's NT-proBNP results, which were measured upon admission and again at 72 hours. The patients were then randomised to receive either usual care or care guided by the NT-proBNP test results. The median level of NT-proBNP in the 230 patients with final diagnoses of acute HF was 3,097 picograms per milliliter (pg/ml), compared to 212 pg/ml in those without acute decompensate HF. In establishing a diagnosis, adding NT-proBNP to clinical judgment enhanced accuracy, the area under the receiver-operating characteristic curve increased from 0.83 to 0.90 (p<0.00001).
About the Roche NT-proBNP Diagnostic Test
The Roche NT-proBNP test is a quick and simple blood test that allows the identification and exclusion of HF by measuring the level of NT-proBNP in a patient's blood(4). In addition, monitoring levels of NT-proBNP can be used to guide drug treatment and in turn reduce the total number of cardiovascular events with clinically guided treatment(5). NT-proBNP is approved by the FDA and recommended by the European Society of Cardiology (ESC), for instance, as an aid in the diagnosis of congestive heart failure (CHF) and assessing its severity and the detection of mild forms of cardiac dysfunction(6).
