Contribution of SuPAR for patients in a situation of uncertainty downstream of emergencies

OBJECTIVES: is a non-specific prognostic inflammatory blood biomarker with a high negative predictive value for pejorative outcomes. The aim of this study was to investigate the relationship between low levels of suPAR at ED admission and patient discharge following hospitalization in a short stay unit. METHODS: We carried out a single-center prospective observational study in the acute-care hospital ward of a university hospital center, including patients over 18 years old with an intermediate triage score. RESULTS: Overall, 202 acute medical patients were included, exhibiting a mean suPAR level of 7.43 ± 3.36 μg/L. Of these patients, 25 (12.4 %) displayed a suPAR dosage below 4 μg/L and 177 (87.6 %) a dosage ≥4 μg/L. At 24 h, 55 patients (27.2 %) were discharged, 139 (68.8 %) were hospitalized, and five (2.5 %) were either admitted to intensive care or died. In contrast to group with a high suPAR rate, those with suPAR
