Abstract
Background: *Soluble urokinase-type plasminogen activator receptor (suPAR) is a new biomarker, which is increased in conditions associated with inflammatory immune cell activation. In low resource, densely populated countries, there is a need for a quick test for triage and prognosticating in the emergency department.
Materials and Methods: *A pilot, observational study was conducted wherein all consenting adult patients (>18 years) presented to casualty with acute medical illnesses were included. Detailed clinical history, examination, and suPAR quick tests were done and patients were categorized into five groups based on the emergency severity index (ESI) triage algorithm. Patients with suPAR level more than 5.5 ng/mL were advised hospitalization and those below were advised follow-up. All patients were followed-up after 3 days.
Results: Total 190 patients (20-80 years), 80 males and 110 females participated. ESI triage 1, 2, and 3 had suPAR levels > 5.5 ng/mL and ESI triage 4 and 5 had suPAR level of <5.5 ng/mL. In ESI-1, 29 patients were admitted in ICU and 16 left against medical advice (LAMA) and on follow-up mortality was 96% (P = <0.05). In ESI-2, all patients were admitted in high dependency units and on follow-up they still needed hospitalization. In ESI-3, 22 patients admitted in ward and 24 went LAMA, on follow-up all improved except LAMA patients who required hospitalization (P - <0.05). Patients in ESI-4 and 5 did not require admission (P = <0.001).
Conclusion: *suPAR can reliably be used in the emergency department to prognosticate and triage.
