Meeting ambitious global health goals with limited resources requires a precision public health (PxPH) approach. Here we describe how integrating data collection optimisation, traditional analytics and causal artificial intelligence/machine learning (ML) can be used in a use case for increasing hospital deliveries of newborns in Uttar Pradesh, India.
Using a systematic behavioural framework we designed a large-scale survey on perceptual, interpersonal and structural drivers of women's behaviour around childbirth (n=5613). Multivariate logistic regression identified factors associated with institutional delivery (ID). Causal ML determined the cause-and-effect ordering of these factors. Variance decomposition was used to parse sources of variation in delivery location, and a supervised learning algorithm was used to distinguish population subgroups.
Among the factors found associated with ID, the causal model showed that having a delivery plan (OR=6.1, 95% CI 6.0 to 6.3), believing the hospital is safer than home (OR=5.4, 95% CI 5.1 to 5.6) and awareness of financial incentives were direct causes of ID (OR=3.4, 95% CI 3.3 to 3.5). Distance to the hospital, borrowing delivery money and the primary decision-maker were not causal. Individual-level factors contributed 69% of variance in delivery location. The segmentation analysis showed four distinct subgroups differentiated by ID risk perception, parity and planning.
These findings generate a holistic picture of the drivers and barriers to ID in Uttar Pradesh and suggest distinct intervention points for different women. This demonstrates data optimised to identify key behavioural drivers, coupled with traditional and ML analytics, can help design a PxPH approach that maximise the impact of limited resources.
在资源有限的情况下实现雄心勃勃的全球健康目标需要采用精准公共卫生(PxPH)方法。本文描述了如何将数据收集优化、传统分析和因果人工智能/机器学习(ML)整合到一个案例中,以提高印度北方邦医院新生儿的分娩率。
我们使用系统行为框架设计了一项关于女性分娩行为的感知、人际和结构驱动因素的大规模调查(n=5613)。多变量逻辑回归确定了与机构分娩(ID)相关的因素。因果 ML 确定了这些因素的因果顺序。方差分解用于解析分娩地点的变化来源,监督学习算法用于区分人群亚组。
在与 ID 相关的因素中,因果模型显示,有分娩计划(OR=6.1,95%CI 6.0 至 6.3)、认为医院比家更安全(OR=5.4,95%CI 5.1 至 5.6)和意识到财务激励是 ID 的直接原因(OR=3.4,95%CI 3.3 至 3.5)。到医院的距离、借贷分娩资金和主要决策者不是因果因素。个体因素对分娩地点的变化贡献了 69%。细分分析显示,有四个不同的亚组通过 ID 风险感知、生育次数和计划来区分。
这些发现为北方邦 ID 的驱动因素和障碍提供了全面的了解,并为不同的女性提供了不同的干预点。这表明,数据优化可用于识别关键行为驱动因素,结合传统和 ML 分析,可帮助设计一种 PxPH 方法,最大限度地利用有限资源的影响力。
