The study of the inclusion of new variables in already existing early warning scores is a growing field. The aim of this work was to determine how capnometry measurements, in the form of end-tidal CO2 (ETCO2) and the perfusion index (PI), could improve the National Early Warning Score (NEWS2). ⋯ The present study findings indicate that the PI and ETCO2 improved the ability of the NEWS2 to predict 30-day in-hospital mortality. The novel association of the NEWS2 with the PI and ETCO2 should be considered since it could improve the identification of patients at risk of clinical worsening.

Evaluating the prognostic value of DECAF score and procalcitonin in patients with COPD exacerbation.
Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) frequently result in emergency department (ED) visits, necessitating accurate risk stratification. The aim of this study was to evaluate and compare the prognostic utility of the DECAF score and serum procalcitonin levels in predicting clinical outcomes in patients with AECOPD. ⋯ The DECAF score and serum procalcitonin levels both exhibit robust prognostic capabilities in excluding adverse outcomes in AECOPD patients, with their predictive accuracy enhanced when used in tandem.
