Improving health systems means finding smarter ways to deliver care, reduce errors, and ensure patients receive the best possible treatment. This field explores how hospitals and clinics can function more effectively, focusing on the practical changes that lead to better outcomes for everyone involved. It is less about discovering new drugs and more about refining the everyday processes that keep our healthcare networks running smoothly.

At Gist.Science, we track every new preprint in this category from medRxiv to bring you the latest research immediately. Our team processes these papers to provide both detailed technical summaries for experts and clear, plain-language explanations for anyone interested in how healthcare can improve. We believe that understanding these systemic changes is vital for building a more resilient future.

Below are the latest studies and insights from the health systems and quality improvement community, sorted by their recent submission dates.

Beyond Injection Detection: A Positive-Security Prompt Firewall that Closes the Scope and PHI Gap SOTA Classifiers Miss in Healthcare

This paper introduces QFIRE, a high-performance Rust-based prompt firewall that addresses critical gaps in healthcare AI safety by combining positive security scope constraints, PHI-specific detection, and de-obfuscation techniques to effectively block legitimate-looking data exfiltration and out-of-scope requests that state-of-the-art injection classifiers miss, all while maintaining low latency and deterministic auditability.
