A fundamental principle of clinical reasoning is that assessment precedes plan; clinicians are taught to base interventions on the presumed etiology of a presentation. A notable exception is in the domain of communication education, where training is focused heavily on tools and interventions, with minimal focus on the assessment that informs which tools or strategies to select with a given patient. The concept of formulation (foundational in psychotherapy education) provides a framework with which to address this gap, enhancing a clinician's ability to be more therapeutically effective with the communication tools at their disposal. Our formulation serves as the compass that guides our decisions around communication, allowing us to conceptualize communication as a therapeutic intervention and align our approach to communication with the broader philosophy of clinical reasoning. This manuscript explores the concept of formulation, the direct relevance and applicability to palliative care, sample cases to underscore the impact of this framework, and high-yield tips for use of formulation in general palliative care practice. Palliative care clinicians and IDTs can readily apply formulation in synergy with the communication tools they already possess, elevating their ability to address patients' psychological needs.
