摘要: 背景 重症肺炎是呼吸系统常见的急危重症,病死率高、社会负担重。早期准确评估重症肺炎患者的病情和预后,有助于临床决策。序贯性脏器功能衰竭(SOFA)评分、CURB-65评分以及肺炎严重指数(PSI)评分可以从不同方面反映肺炎严重程度,然而对于预测重症肺炎预后的最佳风险评分还没有达成共识。 目的 探讨SOFA评分、CURB-65评分及PSI评分对重症肺炎患者短期预后的预测效能。 方法 本研究为多中心、前瞻性观察性研究,选取2017年12月至2022年3月在河南中医药大学第一附属医院等11家医院重症监护室(ICU)和呼吸与危重症医学科住院的重症肺炎患者作为研究对象。根据患者确诊重症肺炎后28 d内是否死亡将其分为存活组和死亡组,于住院当天对患者进行SOFA评分、CURB-65评分和PSI评分。比较两组患者临床特征和3种风险评分。绘制3种风险评分预测重症肺炎患者28 d死亡的受试者工作特征(ROC)曲线,并采用Hosmer-Lemeshow检验和校准度图等评价风险评分的预测效能。使用X-tile v3.6确定最优风险评分的最佳临界值对患者进行分层,并绘制重症肺炎患者Kaplan-Meier生存曲线,采用Log-rank检验进行比较。 结果 最终纳入240例重症肺炎患者,其中28 d死亡57例(23.8%)。死亡组重症肺炎患者年龄高于存活组,血小板计数低于存活组(P<0.05)。死亡组重症肺炎患者SOFA评分、CURB-65评分及PSI评分均高于存活组(P<0.05)。ROC曲线结果显示,SOFA评分预测重症肺炎患者28 d死亡的ROC曲线下面积(AUC)为0.741〔95%CI(0.663,0.820)〕,CURB-65评分为0.627〔95%CI(0.544,0.710)〕,PSI评分为0.621〔95%CI(0.539,0.703)〕。3种风险评分的AUC均>0.6,表明三者对重症肺炎患者28 d死亡均有较好的预测价值(P<0.001),其中SOFA评分的AUC分别高于CURB-65评分和PSI评分(Z=2.492,P=0.013;Z=2.775,P=0.006)。Hosmer-Lemeshow检验和校准度图均提示SOFA评分准确度较好。基于X-tile软件确定的SOFA评分的最佳临界值将患者分为低危组(0~5分)、中危组(6~8分)和高危组(9~18分)。Kaplan-Meier生存曲线分析显示,低、中、高危组重症肺炎患者28 d病死率分别为12.0%(17/142)、28.8%(19/66)、65.6%(21/32)。三组生存曲线比较,差异有统计学意义(χ2=37.93,P<0.001)。 结论 SOFA评分、CURB-65评分及PSI评分均对重症肺炎患者28 d死亡有一定预测作用,其中SOFA评分更具有临床应用价值。

Abstract:

Background

Severe pneumonia is a common critical respiratory illness with high mortality and heavy social burden. Early and accurate assessment of the condition and prognosis of patients with severe pneumonia contributes to clinical decision-making. The Sequential Organ Failure Assessment (SOFA), CURB-65 score, and Pneumonia Severity Index (PSI) score can reflect the severity of pneumonia in different aspects, but there is no consensus on which one of them has the highest performance in predicting the prognosis of severe pneumonia.

Objective

To explore the predictive efficacy of SOFA, CURB-65 and PSI scores for short-term prognosis of patients with severe pneumonia.

Methods

This was a multicenter, prospective observational study. Inpatients with severe pneumonia were selected from the ICU and department of respiratory and critical medicine of 11 hospitals (including the First Affiliated Hospital of Henan University of Traditional Chinese Medicine and other 10 hospitals) from December 2017 to March 2022. The patients were divided into survival group and death group according to the 28-day mortality after diagnosis to compare clinical characteristics and SOFA, CURB-65 and PSI scores assessed on the day of hospitalization. The receiver operating characteristic (ROC) curve was used to assess the performance of three risk scores for predicting the 28-day mortality. The predictive efficacy of the risk scores was evaluated using the Hosmer-Lemeshow test and calibration plot. Optimal risk scores were stratified using X-tile 3.6 to determine the optimal threshold. Kaplan-Meier survival curves of the patients were plotted and compared using the Log-rank test.

Results

A total of 240 patients were included, among whom 57 (23.8%) died within 28 days after diagnosis. Compared with the survival group, the death group had greater average age and lower average platelet count (P<0.05). And the SOFA, CURB-65 and PSI scores in the death group were higher (P<0.05). ROC analysis demonstrated that the values of AUC of SOFA score, CURB-65 score and PSI score were 0.741〔95%CI (0.663, 0.820) 〕, 0.627〔95%CI (0.544, 0.710) 〕, and 0.621〔95%CI (0.539, 0.703) 〕, respectively, all were greater than 0.6, indicating that the three scores had good predictive value for 28-day mortality in severe pneumonia (P<0.001), and the AUC of SOFA score was higher than that of CURB-65 score (Z=2.492, P=0.013) or PSI score (Z=2.775, P=0.006). Both the Hosmer-Lemeshow test and calibration plot suggested that the SOFA score was more accurate. Kaplan-Meier survival analysis showed that 28-day mortalities in low-risk (0-5), moderate-risk (6-8), and high-risk (9-18) patients stratified by SOFA score using the X-tile 3.6 were 12.0% (17/142), 28.8% (19/66), and 65.6% (21/32) respectively (χ2=37.93, P<0.001) .

Conclusion

SOFA, CURB-65 and PSI score are all suitable for predicting 28-day mortality of patients with severe pneumonia, with SOFA score being more valuable for clinical application.
