Introduction to DDx GPT

DDx GPT is a specialized version of the GPT model, tailored for medical professionals and students, with a focus on differential diagnosis (DDx). It is designed to assist in eliciting and processing detailed patient information, including age, symptoms, medical history, and current medications. The primary goal of DDx GPT is to facilitate the creation of accurate and comprehensive differential diagnoses by leveraging its vast knowledge of medical conditions, clinical presentations, and diagnostic criteria. For example, when a healthcare provider inputs patient data—such as a 45-year-old male with chest pain and a history of hypertension—DDx GPT can suggest potential diagnoses, ranging from common conditions like angina to less typical but serious conditions like aortic dissection. It guides the user through relevant questions to refine the diagnosis and offers insights into appropriate diagnostic tests and treatment options. This system is meticulously designed to mirror clinical reasoning, allowing users to interact with it as they would with a clinical decision-support tool. DDx GPT can also access a browser and Python tool for data analysis and up-to-date information retrieval, further enhancing its diagnostic capabilities.

Main Functions of DDx GPT

  • Differential Diagnosis Support

    Example Example

    A primary care physician uses DDx GPT to generate a list of possible diagnoses for a patient presenting with unexplained weight loss, fatigue, and night sweats.

    Example Scenario

    In this scenario, the physician inputs the patient's symptoms, and DDx GPT suggests conditions such as tuberculosis, lymphoma, or HIV, guiding further questioning and investigations. This helps the physician consider a broad range of possibilities, including rare or atypical presentations.

  • Patient Information Elicitation

    Example Example

    A medical student uses DDx GPT during a case study to ensure they gather all relevant patient history, including past surgeries, medications, and lifestyle factors.

    Example Scenario

    DDx GPT prompts the student with structured questions about the patient's history, ensuring that no critical information is missed, which is essential for developing an accurate differential diagnosis.

  • Clinical Decision-Making Assistance

    Example Example

    An emergency room doctor consults DDx GPT for guidance on immediate steps for a patient with sudden onset of severe headache and confusion.

    Example Scenario

    DDx GPT recognizes the presentation as potentially life-threatening and suggests urgent imaging to rule out intracranial hemorrhage, followed by a discussion of possible interventions. This real-time assistance supports the doctor in making swift, informed decisions.

Ideal Users of DDx GPT

  • Healthcare Providers

    This group includes physicians, nurse practitioners, and physician assistants who need support in generating differential diagnoses, especially in complex or uncertain cases. DDx GPT helps them explore all relevant possibilities and avoid diagnostic errors, which is crucial for patient safety and effective treatment.

  • Medical Students and Trainees

    Medical students, residents, and other healthcare trainees benefit from DDx GPT's structured approach to patient interviews and diagnostic reasoning. It serves as an educational tool, helping them develop clinical skills and ensuring they consider a wide range of differential diagnoses during their training.
