Key result
Outpatient BNP testing surges from 8% to ~47% of total volume between 2001 and 2003.
Why the study?
The evolving use of BNP measurements in various clinical settings at a US institution had not been analyzed over time.
Comparison

The clinical utilization of BNP testing rapidly expanded and diversified over a 3-year period, shifting from predominantly emergency department use to widespread outpatient application.
Harrison et al. (2004) conducted an observational in Dyspnea / Heart Failure. B-type natriuretic peptide (BNP) assay utilization vs. Across years (2001, 2002, 2003) was evaluated on Distribution of BNP assays by location across years (p=<0.001). The distribution of BNP assays by clinical location changed significantly from 2001 to 2003 (P<0.001), with outpatient use experiencing the most growth from 8% to 47%.
