A junior orthopaedic surgery resident is completing a carpal tunnel repair
with the department chairman as the attending physician. During the case,
the resident inadvertently cuts a flexor tendon. The tendon is repaired
without complication. The attending tells the resident that the patient
will do fine, and there is no need to report this minor complication that
will not harm the patient, as he does not want to make the patient worry
unnecessarily. He tells the resident to leave this complication out of the
operative report. Which of the following is the correct next action for
the resident to take? A. Disclose the error to the patient and put it in
the operative report B. Tell the attending that he cannot fail to disclose
this mistake C. Report the physician to the ethics committee D. Refuse to
dictate the operative reporty.
context: >-
Inadvertent Cutting of Tendon is a complication, it should be in the
Operative Reports The resident must put this complication in the operative
report and disscuss it with the patient. If there was no harm to the
patent and correction was done then theres nothing major for worry. But
disclosing this as per ethical guidelines, is mandatory

Model Card for MedGENIE-fid-flan-t5-base-medqa
MedGENIE comprises a collection of language models designed to utilize generated contexts, rather than retrieved ones, for addressing multiple-choice open-domain questions in the medical field. Specifically, MedGENIE-fid-flan-t5-base-medqa is a fusion-in-decoder (FID) model based on flan-t5-base, trained on the MedQA-USMLE dataset and grounded on artificial contexts generated by PMC-LLaMA-13B. This model achieves a new state-of-the-art (SOTA) performance over the corresponding test set.

Bias, Risk and Limitation
Our model is trained on artificially generated contextual documents, which might inadvertently magnify inherent biases and depart from clinical and societal norms. This could lead to the spread of convincing medical misinformation. To mitigate this risk, we recommend a cautious approach: domain experts should manually review any output before real-world use. This ethical safeguard is crucial to prevent the dissemination of potentially erroneous or misleading information, particularly within clinical and scientific circles.
