In Malawi, malaria is responsible for 40% of hospital deaths. Prompt diagnosis and effective treatment within 24 h of fever onset is critical to prevent progression from uncomplicated to severe disease and to reduce transmission.
As part of the large evaluation of the malaria vaccine implementation programme (MVIP), this study analysed survey data to investigate whether prompt treatment-seeking behaviour is clustered at community-level according to socio-economic demographics.
From 4563 households included in the survey, 4856 children aged 5-48 months were enrolled. Out of 4732 children with documented gender, 52.2% were female and 47.8% male. Among the 4856 children, 33.8% reported fever in the two weeks prior to the survey. Fever prevalence was high in communities with low socio-economic status (SES) (38.3% [95% CI: 33.7-43.5%]) and low in areas with high SES (29.8% [95% CI: 25.6-34.2%]). Among children with fever, 648 (39.5%) sought treatment promptly i.e., within 24 h from onset of fever symptoms. Children were more likely to be taken for prompt treatment among guardians with secondary education compared to those without formal education (aOR:1.37, 95% CI: 1.11-3.03); in communities with high compared to low SES [aOR: 2.78, 95% CI: 1.27-6.07]. Children were less likely to be taken for prompt treatment if were in communities far beyond 5 km to health facility than within 5 km [aOR: 0.44, 95% CI: 0.21-0.92].
The high heterogeneity in prevalence of fever and levels of prompt treatment-seeking behaviour underscore the need to promote community-level malaria control interventions (such as use of long-lasting insecticide-treated nets (LLINs), indoor residual spraying (IRS), intermittent preventive therapy (IPT), presumptive treatment and education). Programmes aimed at improving treatment-seeking behaviour should consider targeting communities with low SES and those far from health facility.
在马拉维,疟疾导致 40%的医院死亡。发热发病后 24 小时内及时诊断和有效治疗对防止病情从轻症发展为重症以及减少传播至关重要。
作为疟疾疫苗实施规划(MVIP)大型评估的一部分,本研究通过调查数据分析了根据社会经济人口统计学特征,是否存在社区层面上的及时治疗行为聚集现象。
在调查涵盖的 4563 户家庭中,登记了 4856 名 5-48 月龄儿童。在有性别记录的 4732 名儿童中,52.2%为女性,47.8%为男性。在 4856 名儿童中,33.8%在调查前两周报告有发热。社会经济地位(SES)低的社区发热患病率高(38.3%[95%置信区间:33.7-43.5%]),SES 高的地区则低(29.8%[95%置信区间:25.6-34.2%])。在发热儿童中,648 名(39.5%)及时就医,即发热症状出现后 24 小时内。与未接受正规教育的监护人相比,接受过中等教育的监护人更有可能及时带孩子就医(优势比:1.37,95%置信区间:1.11-3.03);与 SES 低的社区相比,SES 高的社区更有可能及时就医(优势比:2.78,95%置信区间:1.27-6.07)。如果儿童所在社区距离卫生机构超过 5 公里,而不是 5 公里内,他们及时就医的可能性较小(优势比:0.44,95%置信区间:0.21-0.92)。
发热的高异质性和及时治疗行为的差异突显了需要促进社区层面的疟疾控制干预措施(如使用长效驱虫蚊帐、室内滞留喷洒、间歇性预防治疗、疑似治疗和教育)。旨在改善治疗行为的方案应考虑以 SES 较低和远离卫生机构的社区为目标。
