Signal Acquisition, Score Interpretation, and Economics of a Non-Invasive Point-of-Care Test for Coronary Artery Disease

Abstract:
To investigate whether the risk of life-threatening complications influence the decisions involving invasive diagnostic procedures, a study was conducted that focused on the use of coronary angiography and endomyocardial biopsy with risk rates of either 1% or 2%. The participants included 38 physicians from two university-affiliated hospitals. Of their 76 pairs of decisions, 53% were of the "risk-avoidance" type and 26% were of the "risk-taking" type. Only 13% of decisions were of the "risk-conscious" type. The practical implication of these biases can be substantial in real-life decisions regarding events with low-probability, but high-consequence risks.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Documentation of Nursing Diagnosis
In some settings, data-driven computerized decision support systems are in place, allowing for more accurate nursing diagnoses. The database within one of these systems includes diagnostic labels defining characteristics, activities, and indicators for nursing. A nurse enters assessment...
