| Objective To explore the value of Oxford Acute Severity of Illness Score(OASIS) and Physiological Scoring System(PSS) in evaluating the severity and prognosis of critical care patients. Methods A total of102 patients admitted to our ICU from August 2016 to August 2017were retrospectively analyzed,among them 30 were in non-survivors group and 72in survivors group. OASIS,PSS and the area under the receiver operating characteristic(ROC) in survivors and non-survivors were calculated. Results OASIS, PSS score and duration of mechanical ventilation of survivors group were(24.64±5.95),(4.18±2.36) and(3.36±3.97)d respectively, those of non-survivors group were(34.60±7.17),(6.47±2.66) and(8.13±9.36)d, respectively, and there wasstatistically significant difference between the two groups(P<0.05).The area under the ROC of OASIS was 0.856(95%CI:0.770~0.942, P<0.05), Youden index wasthe biggest,namely 0.592,when OASIS was 30.5. The area under the ROC of PSS score was 0.747(95%CI:0.637~0.858, P<0.05),Youden index was the biggest,namely 0.421,when PSS score was 5.5. Conclusion Oxford Acute Severity of Illness Score is useful in evaluating the severity and prognosis of critical care patients and superior to PSS. |
