Navigating Appropriateness of Care in the ICU: A Case-Based Application of the Fourfold Assessment.

Abstract

PurposeAppropriateness of care is a fundamental yet often underexamined aspect of critical care medicine. Drawing on Kant's notion of appropriateness as providing "no more and no less than the matter requires," we explore how clinicians can align medical indication with patient or surrogate consent. Misalignments in this regard may result in overtreatment or undertreatment, contributing to moral distress, burnout, and dissatisfaction among families and clinicians.MethodsWe present a case report of an elderly patient whose clinical course in the intensive care unit (ICU) traverses all four quadrants of a proposed framework-the Fourfold Table of Appropriateness. This conceptual tool classifies medical interventions according to two dimensions: medical indication (yes/no) and patient or surrogate consent (yes/no). Each quadrant is associated with ethical and clinical implications and is color-coded like a traffic light to support real-time decision-making: green (appropriate), yellow (caution), red (stop).ResultsThe case illustrates how alignment between indication and consent fosters goal-concordant care. It also demonstrates how therapeutic obstinance, paternalism, or emotionally driven demands may lead to inappropriate care. Each episode reveals different challenges-physician biases, surrogate distress, unclear prognoses-and highlights the role of communication, shared decision-making, and clinical humility.ConclusionThe Fourfold Table provides a didactic framework to guide structured reflection among ICU clinicians. By naming and examining patterns of inappropriateness, it fosters ethical awareness and better communication practices. This case-based approach highlights the necessity of early recognition of misalignments, the importance of addressing emotional and cognitive biases, and the value of interventions such as time-limited trials and family-centered care. Ultimately, this framework contributes to more compassionate, appropriate, and goal-aligned critical care.
