Patient flow and access block will be evaluated through comparing time to decision making in the Emergency Department (ED) and Emergency Department length of stay (ED LOS) between patients who have POC and Laboratory BNP testing. Cost effectiveness will be evaluated by reviewing treatment type given, admission rate, ICU admission rate, inpatient length of stay (IP LOS), Emergency Department Length of Stay and 30day readmission rate.
This study will build upon the findings of a similar concurrent study. Both studies demonstrate a poor utility in BNP testing in patients presenting with shortness of breath in reducing Emergency Department length of stay. While this limits the potential for BNP Point of care testing within the ED, the validated Abbott Point of Care BNP cartridge will have the good potential for improving patient care in rural and remote cardiac outpatient locations where current BNP testing results take several days to obtain.
One-hundred fifty consecutive adult patients presenting with acute dyspnea to Nambour Hospital Emergency Department were recruited. B-type natriuretic peptide levels were compared (using the Abbott POC analyzer and the laboratory), as were grouped levels using clinically useful accepted reference ranges (<100, 100-500, and >500 pg/mL). The data were tested using general correlation and least squares regression.
The correlation between the POC and laboratory BNP results was strong, R2 = 0.87. There is a good correlation for the measurement of BNP between Abbott POC BNP and laboratory BNP analyzer. The Abbott (Chicago, Ill) POC BNP analyzer is suitable for measurement of BNP in Australian emergency departments.
