Clinical effectiveness

Ability of a test to improve health outcomes that are relevant to the individual patient.

Example

  • The clinical effectiveness of BNP testing for diagnosis of heart failure in patients presenting to emergency with acute dyspnea were investigated in RCTs that compared the addition of BNP testing with standard investigations alone followed by routine care. A meta-analysis of these RCTs reported that addition of BNP testing decreased length of hospital stay by ~1 day; possibly reduced admission rates, but did not affect 30-day mortality rates.
