Hypothesis
This study aimed to compare the prognostic utility of A-DROP, NEWS2, and REMS in predicting in-hospital mortality and the requirement for mechanical ventilation among ED patients with pneumonia.
Conclusion
A-DROP had the highest prognostic utility for predicting in-hospital mortality in non-COVID-19 pneumonia patients in the ED compared to NEWS2 and REMS.
Supporting Evidence
- A-DROP had the highest discrimination capacity for in-hospital mortality.
- 272 patients (37%) died at hospital discharge.
- 75 patients (10.2%) required mechanical ventilation.
- A-DROP showed superior calibration and overall model performance compared to NEWS2 and REMS.
Takeaway
Doctors used three scoring systems to see which one could best predict if pneumonia patients would die in the hospital. They found that one score, A-DROP, was the best at predicting this.
Methodology
A retrospective cohort study was conducted at the ED of Siriraj Hospital, Thailand, including adult patients diagnosed with non-COVID-19 pneumonia.
Potential Biases
The retrospective nature of the study may introduce biases related to data collection and patient selection.
Limitations
The study was a single-center retrospective study, which may limit generalizability, and the primary outcome was all-cause mortality, which may not be specific to pneumonia.
Participant Demographics
Adult patients diagnosed with non-COVID-19 pneumonia, with a mean age of 73.6 years for those who died and 69.8 years for those who survived.
