Background |
Little is known about the accuracy of the quick Sequential Organ Failure Assessment (qSOFA) and the National Early Warning Score (NEWS) in identifying sepsis patients with a history of hypertension on anti-hypertensive agents, which affect vital signs as components of the scoring systems. We aimed to examine the ability of qSOFA and NEWS to predict sepsis among anti-hypertensive agent users by comparing them with non-users.
Methods |
We retrospectively identified adult patients (aged ≥18years) with suspected infection who presented to an emergency department (ED) of a large tertiary medical center in Japan between April 2018 and March 2020. Suspected infection was defined based on the chief complaint of fever, high body temperature, or the clinical context on arrival at the ED. We excluded patients who had trauma or cardiac arrest, those who were transported to other hospitals after arrival at the ED, and those whose vital signs data were mostly missing. The predictive performances of qSOFA and NEWS based on initial vital signs were examined separately for sepsis, ICU admission, and in-hospital mortality and compared between anti-hypertensive agent users and non-users.
Results |
Among 2900 patients with suspected infection presenting to the ED, 291 (10%) had sepsis, 1023 (35%) were admitted to the ICU, and 188 (6.5%) died. The prediction performances of qSOFA and NEWS for each outcome among anti-hypertensive agent users were lower than that among non-users (e.g., c-statistics of qSOFA for sepsis, 0.66 vs. 0.71, p = 0.07; and for ICU admission, 0.70 vs. 0.75, p = 0.01). For identifying sepsis, the sensitivity and specificity of qSOFA ≥2 were 0.43 and 0.77 in anti-hypertensive agent users and 0.51 and 0.82 in non-users. Similar associations were observed for identifying ICU admission and in-hospital mortality. Regardless of the use of anti-hypertensive agents, NEWS had better prediction abilities for each outcome than qSOFA.
Conclusion |
The clinical performance of qSOFA and NEWS for identifying sepsis among anti-hypertensive agent users was likely lower than that among non-users.
