Additional value of geriatric parameters to Quick Sepsis Related Organ Failure Assessment score for predicting clinical deterioration in older emergency department patients with a suspected infection: post-hoc analysis of a prospective observational study.

Aim: To investigate the additional value of geriatric parameters such as physical impairment to the quick Sequential Organ Failure Assessment (qSOFA) tool for predicting clinical deterioration in older ED patients with a suspected infection and to validate the final prediction model.

Methods: Post-hoc multivariable regression analysis from a prospective observational cohort study of adult patients visiting the ED of a university hospital to develop a prediction model. External validation of the prediction model was performed using the prospective data-biobank Acutelines.
