Impact of age and renal function on usefulness of NT-proBNP to diagnose heart failure .

Aims: NT-proBNP is a useful biomarker for heart failure (HF) diagnosis. We aimed to determine NT-proBNP's ability to diagnose HF by age and renal function.

Materials And Methods: We analyzed 3,699 consecutive and unique adults admitted for dyspnea at the Emergency Unit of St.

Establishment of indicators to improve clinical analysis prescribing patterns.

An appropriate medical analysis prescribing pattern is part of the medical biologists' work as it enhances patient care and reduces costs. In this study, we use four indicators to aim to evaluate the relevance of clinical analysis prescription. We confronted clinical data and medical analysis prescribed in June 2013 in the emergency department (ED) and found that prescriptions were justified in 73% of TnT prescriptions but only in less than 50% of NTproBNP (27%), APTT (37%), PR (33%) or INR (23%) prescriptions.
