(1) To determine whether mortality rates were raised in sick children in the 30 days after visiting first-level health facilities in an area under demographic surveillance in western Kenya, (2) to identify the types of illnesses associated with increased mortality and (3) to estimate the effectiveness of appropriate treatment.
All sick children (2-59 months of age) who attended one of the seven participating first-level health facilities from May to August 2003 were identified. A standardized mortality ratio was computed to compare their mortality rate in the 30 days after a sick visit with that of the community under active demographic and health surveillance. A multivariate Cox Proportional Hazards model was used to identify illnesses associated with death and to estimate the protective effectiveness of appropriate treatment for potentially life-threatening diseases.
A total of 1383 eligible children made 1697 sick visits; 33 (2.4%) died within 30 days. Compared with children 2-59 months in the general population, sick children had a 5.3 times greater mortality rate [95% confidence interval (CI) 3.8-7.5]. In a multivariate survival analysis, significant risk factors for mortality included age <24 months [Hazard Ratio (HR) 4.4, 95% CI 1.5-12.6], malnutrition (HR 15.5, 95% CI 6.1-39.8), severe pneumonia (HR 12.9, 95% CI 3.0-56.4) and anaemia (HR 3.3, 95% CI 1.5-7.2). Appropriate treatment for a child's most severe illness reduced mortality by 78% (95% CI 57-89%).
We estimate that improvements in diagnosis and appropriate treatment at first-level health facilities for children 2-59 months could reduce overall under-5 mortality in the area by 12-14%.
(1)确定在肯尼亚西部人口监测地区,患病儿童在就诊一级医疗机构后的30天内死亡率是否升高;(2)识别与死亡率增加相关的疾病类型;(3)评估适当治疗的有效性。
确定2003年5月至8月期间在七个参与研究的一级医疗机构之一就诊的所有患病儿童(2至59个月大)。计算标准化死亡率,以比较他们患病就诊后30天内的死亡率与处于活跃人口和健康监测下的社区的死亡率。使用多变量Cox比例风险模型来识别与死亡相关的疾病,并评估对潜在危及生命疾病的适当治疗的保护效果。
共有1383名符合条件的儿童进行了1697次患病就诊;33名(2.4%)在30天内死亡。与一般人群中2至59个月大的儿童相比,患病儿童的死亡率高出5.3倍[95%置信区间(CI)3.8 - 7.5]。在多变量生存分析中,死亡率的显著风险因素包括年龄<24个月[风险比(HR)4.4,95% CI 1.5 - 12.6]、营养不良(HR 15.5,95% CI 6.1 - 39.8)、重症肺炎(HR 12.9,95% CI 3.0 - 56.4)和贫血(HR 3.3,95% CI 1.5 - 7.2)。对儿童最严重疾病的适当治疗可使死亡率降低78%(95% CI 57 - 89%)。
我们估计,改善一级医疗机构对2至59个月大儿童的诊断和适当治疗,可使该地区5岁以下儿童的总体死亡率降低12%至14%。
