Towards a solution to the global healthcare crisis: using hierarchical decomposition and theory of constraints (TOC) to address the healthcare supply chain wicked problem.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Healthcare is facing a crisis globally, with rising demand and technological advances escalating costs and outpacing supply. The healthcare supply chain (HCSC) encompasses various links, from primary and specialty care to hospitals, which often fail to function quickly, seamlessly, or cost-effectively individually or together. Indeed, the complexities of healthcare make this a "wicked problem" without easy solutions. Research has typically focused on individual links in the supply chain oversimplifying and neglecting their interdependence. Key characteristics - such as the system's hierarchical structure, diverse stakeholder involvement, interdependencies among links, the importance of timeliness, and the need to cope with complexity, change, and uncertainty - are frequently overlooked. Addressing the healthcare crisis requires a pragmatic approach to improving service delivery. This paper advocates for a systems perspective, allowing a breakdown of the problem into manageable units of analysis based on the system hierarchy, viewing each link in the HCSC as integral to the whole. We outline a multimethodology that capitalises on HCSC characteristics to enhance patient flow and provide timely, high-quality, and cost-effective care. It emphasises classifying, prioritising, and synchronising treatment based on urgency. The paper also discusses existing solutions to the system's components and presents a comprehensive strategy for the overall issue.
