OBJECTIVE:

To compare in-hospital mortality predictive capacity of quick Sequential Organ Failure Assessment (qSOFA) and Systemic Inflammatory Response Syndrome (SIRS) in adult patients admitted with suspected infection.

MATERIAL AND METHOD:

A descriptive, cross-sectional study was carried out from January to July 2017 with a non-experimental design in adult patients admitted with infection of different source to the Hospital General del Sur Dr. Pedro Iturbe from Maracaibo city, Venezuela, selected by an intentional sampling. We quantified the qSOFA and SIRS scores, comparing the characteristics of admission, days of stay and in-hospital mortality in the two groups.

RESULTS:

There were included 60 subjects, 51.6% were men; the most frequent infectious source was the urinary tract with 43.3%, the use of vasoactive agents was necessary in 40% of the patients, while in-hospital mortality occurred in 45% of cases. The quick SOFA score was associated with a greater percentage of in-hospital mortality compared to the SIRS score, also exhibiting a greater predictive capacity with sensitivity of 96%, specificity of 33%, positive predictive value of 54%, negative predictive value of 92%, positive likelihood ratio: 1.4, negative likelihood ratio: 0.1 and area under the curve of 0.77 (0.65-0.89).

CONCLUSION:

The quick SOFA score showed greater sensitivity and specificity for in-hospital mortality compared to the SIRS.
