Objective:
The aim of this study was to compare quick Sepsis-related Organ Failure Assessment (qSOFA) and Systemic Inflammatory Response Syndrome (SIRS) scores for predicting mortality.
Patients And Methods:
A single-center, retrospective study of adult patients with suspected infection was conducted. Area under the curve (AUC) and multivariate analyses were used to explore associations between the qSOFA and SIRS scores and mortality.
Results:
Of the 69 115 patients enrolled, 1798 died within 72 h and 5640 within 28 days. The qSOFA scores were better than SIRS scores at predicting 72-h mortality (AUC: 0.77 vs. 0.64). However, the discriminatory power of both scores was low in terms of 28-day mortality (AUC: 0.69 vs. 0.60). Patients with qSOFA score of at least 2 had a higher hazard ratio for 72-h mortality than for 28-day mortality (2.64 vs. 1.91).
Conclusion:
The qSOFA scores are more accurate than SIRS scores for predicting 72-h mortality and are better at predicting 72-h mortality than 28-day mortality.

01:03Prediction Intervals
However, the point estimate is most likely not the exact value of the population parameter, but close to it. After calculating point estimates, we construct interval estimates, called confidence intervals or prediction intervals. This prediction interval comprises a range of values unlike the point estimate and is a better predictor of the observed sample value, y.
