Study:  

Quezada, Carlos Andrés, et al. "Accuracy and interobserver reliability of the simplified pulmonary embolism severity index versus the hestia criteria for patients with pulmonary embolism." Academic Emergency Medicine (2018).

Outcome measure:

Compare the accuracy and interobserver reliability of the sPESI and Hestia criteria for predicting short term mortality in patients with pulmonary embolism

Methods:

- Prospective cohort study, single center (large/tertiary/academic center)

- 488 adult patients diagnosed with symptomatic PE in the ED

- Compared sPESI and Hestia criteria accuracy for 30 day all cause mortality and interobserver reliability for classifying patients as low or high risk

Results:

- sPESI and Hestia both classified approximately one quarter of patients as low risk (28% vs 27%, respectively)

- Patients classified as low risk had similar rate of all cause mortality with no statistical difference (sPESI 0.7% vs Hestia 2.3%)

- Both had good interobserver reliability (disagreement in 1.2% with sPESI and 7.6% with Hestia)

Conclusion:

Both tools identified similar numbers of patients as low risk and both had similar 30 day all cause mortality, interobserver reliability was better with sPESI
