: For every item on the problem list, a specific plan is formulated. This includes diagnostic studies (to narrow the diagnosis), therapeutic interventions, and patient education. Progress Notes (SOAP)

Implementing a rigorous problem-oriented diagnostic framework offers significant advantages across the healthcare ecosystem:

: Vital signs, physical exam findings, lab trends, and imaging results.

Specific medical interventions, surgeries, physical therapy, or immediate lifestyle modifications.

Before Dr. Weed’s innovation, medical charts were largely "source-oriented." Notes from physicians, nurses, laboratory results, and imaging reports were grouped by their source rather than the patient's specific conditions. This traditional structure often resulted in fragmented data, making it difficult to track the narrative of a complex illness or understand the clinical reasoning behind specific treatments.

The patient’s current symptoms, feelings, and self-reported progress.

Resident physicians and medical students develop structured clinical reasoning skills, learning to separate subjective complaints from objective clinical data systematically. Challenges and Best Practices
