CLINICAL FINDINGS AND BLOOD GAS PARAMETERS IN PATIENTS PRESENTED WITH DYSPNEA

Abstract

ObjectiveTo determine the effectiveness of Objective Classification Scale (OCS-9 scores) at the emergency department on the patients presenting with complaintsof dyspnea.Materials and MethodsThe study was performed retrospectively on 373 patients with respiratory distress. Three important parameters of blood gas (pH, base deficit, lactate level)were used to calculate the OCS-9 value of patientswho were admitted with dyspnea. Clinical parametersand blood gas parameters (OCS-9 scores) were compared with the outcome status of the patients (discharge, service stay, intensive care stay, exitus).ResultsIn the differentiation of the clinical outcomes of thepatients, the effectiveness of the OCS-9 value wasfound to be significant. OCS-9 scores of the patientswho were hospitalized at a regular ward or who were discharged were higher than those who were hospitalized at the intensive care unit (ICU). When cut-off value for OCS-9 score was accepted as 1, its sensitivityfor predicting exitus and hospitalization at an ICU was46.9% and specificity was 77.08%.ConclusionWe suggest that the OCS-9 score may be used asa method to help predict clinical outcomes and shortterm prognosis in patients presenting to the emergency room with dyspnea.
