In the evolving landscape of clinical diagnostics, where resource limitations increasingly dictate testing protocols, the integration of value-of-information (VoI) principles within decision-theoretic models offers a transformative approach to optimizing test selection. This conceptual manuscript proposes a novel framework that embeds VoI diagnostics into cost-constrained clinical testing environments, enabling healthcare providers to prioritize tests based on their informational yield relative to economic burdens. Drawing from decision theory, the framework articulates a structured methodology for evaluating diagnostic tests not merely by accuracy but by their capacity to reduce uncertainty in clinical decision-making under budgetary constraints. Key components include a layered architecture that incorporates probabilistic assessments of test outcomes, utility functions for health gains, and iterative feedback mechanisms to refine selections dynamically. Theoretical formulas are introduced to interpret risk propagation in test cascades and decision confidence amid cost thresholds. By synthesizing recent literature on VoI in healthcare, this work highlights how such a framework could mitigate over-testing, enhance resource allocation, and align diagnostic strategies with value-based care paradigms. While conceptual in nature, the implications extend to infrastructural designs in AI-supported healthcare systems, fostering more equitable and efficient clinical pathways. Ultimately, this decision-theoretic lens reframes test selection as an optimization problem, balancing informational value against fiscal realities in diagnostic workflows.
