A Universal Binary Decision Framework for the Patient Journey: From First Contact to Definitive Intervention

Clinical decision-making is usually taught specialty by specialty, with the logic of each decision left implicit. This Perspective proposes that, from first patient contact to definitive intervention, care resolves into a small set of sequential binary decisions: Do Something or Not; Physics (mechanical) or Chemistry (pharmacological and biological); Invasive or Non-invasive, a distinction that recurs identically under both; Symptomatic or Root Problem; and, for root-problem correction in the musculoskeletal system, Joint Preserving or Joint Destructive. I argue that every terminal branch pursues the same objective, restoration of biomechanical and biochemical parity, and that branches differ in mechanism and in whether motion is retained, not in goal. A corollary is that an intervention drawn from the wrong branch fails regardless of technical execution, illustrated by temporomandibular disorders presenting as dental or sinus infection. The same preserve-or-destroy binary appears in peripheral nerve surgery, chemodenervation, and cardiac catheter ablation. A bone-level classification (osteoereisis) is used as a brief worked example of the same two-axis logic — Conservative or Surgical, then Motion or Fusion-Fixation — recurring within a single specialty. Implications for education, informed consent, and procedure classification are discussed. The framework is conceptual and untested empirically; it is offered as a shared vocabulary, not a replacement for specialty-specific judgment.
