急性卒中后肺炎对卒中近期预后影响的前瞻性研究

目的 探讨急性卒中后肺炎对卒中近期预后的影响.方法 对上海交通大学附属第六人民医院金山分院神经内科自2008年1月1日至2010年6月30日住院治疗的急性卒中患者进行前瞻性研究观察,比较肺炎组与非肺炎组入院时和入院后21 d神经功能缺损程度(NIHSS)、残障程度(mRS)及日常生活能力(BI),比较2组患者其他并发症发生率、病死率、住院时间及治疗费用.结果 (1)人院后21 d,市炎组NIHSS改善程度明显低于非肺炎组改善值-(1.04±1.20)vs(1.37±2.48)],但差异无统计学意义(P=0.663);mRS、BI改善程度明显低于非肺炎组改善值-(0.12±0.33)vs-(0.64±0.82);3.00±6.55 vs 14.70±19.45],差异均有统计学意义(P＜0.05).(2)肺炎组其他并发症发生率、病死率明显高于非肺炎组(80.0%vs19.0%;16.7%vs2.5%),差异均有统计学意义(P＜0.05).(3)肺炎组住院时间明显长于非肺炎组(35±17)dvs(23±11)d],住院总费用及药物费用均明显高于非肺炎组(8509±4425)元vs(4867±1648)元;(4089±2709)元vs(2168±795)元],差异均有统计学意义(P＜0.05).结论 急性卒中后肺炎是导致卒中病死率增加、近期临床预后不良、住院时间延长、医疗费用增加的重要因素.

Abstract：

Objective To study the influence of acute post-stroke pneumonia on short-term prognosis of acute stroke. Methods A prospective, observational study of inpatients with acute stroke,admitted to our hospital from January 1, 2008 to June 30, 2010, was carried out. All the selected patients were divided into pneumonia group and non-pneumonia group. Neurological deficit (NIHSS), disability (modified Rankin Scale, mRS) and activity of daily living (Barthel Index, BI) between these 2 groups were compared on the day of admission and the 21st day of admission; the incidence of other complications, the mortality rate, the hospital length of stay (LOS), and the total costs of hospitalization and drugs between these 2 groups were compared. Results The improvement (NIHSS) in pneumonia group (-1.04±1.20]) was less significant than that in non-pneumonia group (-1.37±2.48]), but their differences were not statistically significant (P=0.663); the improvement (mRS and BI, respectively) in pneumonia group (-0.12±0.33], 3.00±6.55) was obviously less significant than that in non-pneumonia group (-0.64±0.82], 14.70±19.45, P＜0.05). The incidences of other complications and mortality rate in pneumonia group were significantly higher than those in non-pneumonia group (80.0% vs. 19.0%, 16.7%vs. 2.5%, P＜0.05). As compared with those in patients of pneumonia group, patients of non-pneumonia group had shorter LOS(23±11) d vs. (35±17) d, P＜0.05], less total costs ofhospitalization(4867±1648)$ vs. (8509±4425)$, P＜0.05] and less drug costs (2168±795)$ vs. (4089±2709)$, P＜0.05].Conclusion Acute post-stroke pneumonia was an important factor that leads to increased acute stroke mortality rate, poor short-term clinical prognosis, prolonged LOS and increased treatment costs.
