This problem is complicated by limited high-quality data, which restricts the applicability of traditional data-driven techniques. We propose a novel decision-aware machine learning framework for essential medicines allocation, which additionally leverages multi-task learning to ensure sample efficiency and catalytic priors to ensure equitable allocation. In collaboration with the Sierra Leone national government, we performed a staggered, nationwide deployment of our system as a decision support tool. Our econometric evaluation finds an estimated 19% increase in consumption of allocated products in treated districts, demonstrating its efficacy at improving access to essential medicines. Our tool was subsequently scaled nationwide, covering an estimated 2 million women and children under five. Our work demonstrates how machine learning methods can improve efficiency at very low cost in resource-constrained global health settings.", "url": "https://wpnews.pro/news/improving-access-to-essential-medicines-via-decision-aware-machine-learning", "canonical_source": "https://arxiv.org/abs/2607.20542", "published_at": "2026-07-24 04:00:00+00:00", "updated_at": "2026-07-24 04:13:03.787425+00:00", "lang": "en", "topics": ["machine-learning", "ai-products"], "entities": ["Sierra Leone national government"], "alternates": {"html": "https://wpnews.pro/news/improving-access-to-essential-medicines-via-decision-aware-machine-learning", "markdown": "https://wpnews.pro/news/improving-access-to-essential-medicines-via-decision-aware-machine-learning.md", "text": "https://wpnews.pro/news/improving-access-to-essential-medicines-via-decision-aware-machine-learning.txt", "jsonld": "https://wpnews.pro/news/improving-access-to-essential-medicines-via-decision-aware-machine-learning.jsonld"}}
