Estimation of the Possible Economic Effects of a Sequential Testing Strategy with NT-ProBNP before Echocardiography in Primary Care by Banafsheh Seyyed Khezri, Johanna Helmersson-Karlqvist, Anders Larsson

Background: The object of the study was to estimate the possible economic effects of a sequential testing strategy with NT-proBNP from a primary care payer perspective.
Methods: The study data were collected from primary care physicians in the County of Uppland from 2005 through 2012. Two different cut-off levels were used for negative NT-proBNP in the rule-out test: 300 and 400 pg/ mL. The cost-effectiveness of the testing strategy was estimated through the short-term cost avoidance and reduction in demand for echocardiographies.
Results: The female patients were slightly older than the males. Based on the data from 2012, the estimated costs for NT-proBNP tests and echocardiographies per county were reduced by EUR 300000/100000 inhabitants with the 300 pg/mL cut-off and EUR 350000/100000 inhabitants with the 400 pg/mL.
Conclusions: The use of NT-proBNP as a rule-out test in a sequential testing strategy reduced the cost for diagnostic work-up of primary care patients with suspected heart failure.
