Generally speaking, all of these potential tools fall far short of demonstrating their value. Each shows some predictive power to address their problem of interest. Many lack prospective, operational comparisons with presently available objective adjuncts to clinical judgment, such as procalcitonin and CRP, and none robustly demonstrate superiority. Most importantly, no studies of these tests report on prospective implementation and impact on either surrogates for sepsis management, such as antibiotic administration and appropriateness, or patient-oriented outcomes relating to morbidity or mortality. While these are exciting times to witness the development of new tools, remain cautious about adoption before their value is proven.
