【摘要】目的 探讨改良型CURB-65评分在评估急诊患者社区获得性肺炎(community-acquired pneumonia,CAP)严重程度中的临床应用价值。

访法 选择2011年5月至2012年5月期间收住南京市第一医院符合CAP诊断的198例急诊患者,分别应用CURB-65及改良型CURB-65评分进行评估,根据CAP严重程度分为轻症肺炎组(A组107例)、重症肺炎组(B组91例),并记录白细胞总数、降钙素原、肺炎严重指数、住院天数、住院费用,进行成组t检验比较。B组分为存活亚组(62例)与死亡亚组(29例),进行CURB-65及改良型CURB-65评分成组t检验比较。采用Pearson等级相关法分析CURB-65及改良型CURB-65评分与降钙素原、肺炎严重指数、住院天数、住院费用的相关性。

结果 B组患者的降钙素原、肺炎严重指数、住院天数、住院费用、CURB-65评分、改良型CURB-65评分显著高于A组[ (3.70±0.83) vs. (1.27±0.24), t=28.91,P<0.01; (121.33±16.74) vs. (73.79±9.21), t=25.23,P<0.01; (25.79±10.13) vs. (14.85±6.83), t=9.02,P<0.01; (22.71±3.84) vs. (9.83±1.24), t=32.76,P<0.01; (3.69±1.03 )vs. (3.32±1.06), t=2.48,P<0.05; (4.21±1.13) vs. (3.41±0.96), t=5.39,P<0.01],而白细胞总数比较则差异无统计学意义[(17.58±5.99) vs. (16.86±4.41), t=0.97,P>0.05);在B组患者中,改良型CURB-65评分死亡亚组明显高于存活亚组,两组比较差异具有统计学意义[(4.75±1.17) vs. (4.01±1.09), t=2.95, P<0.01],而CURB-65评分两者差异无统计学意义[(4.01±1.15) vs. (3.58±0.97), t=1.86,P>0.05];CURB-65仅与降钙素原呈正相关P<0.05(r= 0.803,P=0.025),与肺炎严重指数、住院天数、住院费用无明显相关性P>0.05(r= 0.621,P=0.320;r= 0.701,P=0.231;r= 0.675,P=0.256);改良型CURB-65评分与降钙素原、肺炎严重指数、住院天数、住院费用呈显著正相关P<0.01(r= 0.951,P=0.003;r= 0.965,P=0.002;r= 0.947,P=0.004;r= 0.961,P=0.002)。

结论 对于急诊患者,改良型CURB-65评分较CURB-65评分能更有效评估CAP的严重程度并判断预后。

【Abstract】Objective To evaluate the clinical application value of modified CURB-65 score for assessing severity of community-acquired pneumonia(CAP) in emergency patients. Methods During the period from May 2011 to May 2012, 198 emergency patients with CAP enrolled in this study were evaluated by CURB-65 score and modified CURB-65 score, respectively. Based on the severity of CAP, patients were divided into mild pneumonia group (Group A, n=107) and severe pneumonia group(Group B, n=91). The clinical status and biomarkers (the white blood cell count, procalcitonin, pneumonia severity index, hospitalization days, and hospitalization expenses) were recorded and compared with t test. Group B was divided into survived- subgroup(n=62) and death- subgroup(n=29). The differences in CURB-65 score and modified CURB-65 score between the two groups were compared with t test. The correlation of CURB-65 score and modified CURB-65 score with procalcitonin, pneumonia severity index, hospitalization days, and hospitalization expenses were determined with Pearson rank correlation method. Results The procalcitonin, pneumonia severity index, hospitalization days, hospitalization expenses , modified CURB-65 score and CURB-65 score in Group B were significantly higher than those in Group A [(3.70±0.83) vs. (1.27±0.24), t=28.91,P<0.01; (121.33±16.74) vs. (73.79±9.21), t=25.23,P<0.01; (25.79±10.13) vs. (14.85±6.83), t=9.02,P<0.01; (22.71±3.84 )vs. (9.83±1.24), t=32.76,P<0.01; (3.69±1.03) vs. (3.32±1.06), t=2.48,P<0.05; (4.21±1.13 )vs. (3.41±0.96), t=5.39,P<0.01] , while no significant difference was observed in the white blood cell count between Group A and B(17.58±5.99 vs. 16.86±4.41, t=0.97,P>0.05). For Group B, the modified CURB-65 score of death- subgroup was significantly higher than that of survived- subgroup [(4.75±1.17) vs. (4.01±1.09), t=2.95, P<0.01], while no significant difference was observed in the CURB-65 score between the death- subgroup and survived- subgroup (4.01±1.15 vs. 3.58±0.97, t=1.86,P>0.05). The CURB-65 score positive correlated with the procalcitonin (r= -0.803,P=0.025), and had no obvious correlation with the pneumonia severity index, hospitalization days, and hospitalization expenses(r= 0.621,P=0.320;r= 0.701,P=0.231;r= 0.675,P=0.256); The modified CURB-65 score significantly positively correlated with the procalcitonin, pneumonia severity index, hospitalization days, and hospitalization expenses (r= 0.951,P=0.003;r= 0.965,P=0.002;r= 0.947,P=0.004;r= 0.961,P=0.002). Conclusions Compared with the CURB-65 score, the modified CURB-65 score is more efficient in evaluating the severity and prognoses of CAP for emergency patients.

CURB-65评分在临床急诊科用于评估社区获得性肺炎(community-acquired pneumonia,CAP)的严重程度,因只需要5个参数(意识、血尿素氮、呼吸频率、血压及年龄),和应用简单快捷,而被广泛应用于急诊患者。但CURB-65评分中血尿素氮、呼吸频率及血压易受多种临床因素影响,从而对CAP严重程度评估造成干扰。……
