Prognostic value of shock index, modified shock index, respiratory-adjusted shock index, and age shock index in pneumonia

Purpose

The aim of this study was to evaluate shock index (SI), modified SI (mSI), respiratory-adjusted SI (RASI), and age SI (aSI) scores, which are calculated using only age and vital signs, on 30-day mortality in patients presenting to the emergency department (ED) with pneumonia. Materials and Methods: This single-center, prospective cohort study included 378 patients who presented to the ED of Pamukkale University Hospital between February 2023 and January 2024 and were diagnosed with pneumonia. We evaluated the association between their clinicodemographic characteristics, including SI, mSI, RASI, aSI, and ED outcome, which was mortality within 30 days of presentation.
