Abstract：Objective To analyze the predictive value of qSOFA score and CURB-65 score in assessing the severity and prognosis of community acquired pneumonia(CAP).Methods 180 patients with community or acquired pneumonia admitted in the respiratory department of our hospital from April 2021 to June 2022 were retrospectively collected.According to the treatment outcome,they were divided into death group(n=30)and survival group(n=150).According to the diagnosis and grading criteria of adult community-acquired pneumonia in China in 2016,they were divided into severe group(n=80)and non severe group(n=100).The main adverse outcomes were death and severe.The predictive value of qSOFA score and CURB-65 score on disease severity and prognosis was analyzed by ROC curve.Results There were statistically significant differences in age,respiratory rate,systolic blood pressure,blood lactic acid,qSOFA score and CURB-65 score between the death group and the survival group(P<0.05).There were statistically significant differences in age,respiratory rate,systolic blood pressure,blood lactic acid,qSOFA score and CURB-65 score between the severe group and the non severe group(P<0.05).In severe CAP,the sensitivity of CURB-65 score was 70.31%,specificity was 83.25%,the sensitivity of qSOFA score was 58.14%,specificity was 89.80%,the sensitivity of Age Lac qSOFA score was 97.15%,specificity was 79.88%,the sensitivity of Age qSOFA score was 98.05%,specificity was 29.82%,the sensitivity of Lac qSOFA score was 82.16%,specificity was 62.27%.In death,the sensitivity of CURB-65 score was 38.15%,the specificity was 83.25%,the sensitivity of qSOFA score was 49.80%,the specificity was 92.0%,the sensitivity of Age Lac qSOFA score was 91.53%,the specificity was 83.45%,the sensitivity of Age qSOFA score was 82.12%,the specificity was 39.42%,and the sensitivity of Lac qSOFA score was 96.26%,the specificity was 36.15%.The prediction ability of Age qSOFA score and Lac qSOFA score is low,while that of Age Lac qSOFA score is high.Conclusion qSOFA score and CURB-65 score have high predictive value for severe cases and death of CAP,but after optimizing qSOFA score,Age Lac qSOFA score has high predictive value.
