Welcome to Core IM, a virtual medical community! Core IM strives to empower its colleagues of all levels and backgrounds with clinically applicable information as well as inspire curiosity and critical thinking. Core IM promotes its mission through podcasts and other multimodal dialogues. ACP has teamed up with Core IM to offer continuing medical education, available exclusively to ACP members by completing the CME/MOC quiz.

1. Intro
2. Case Introduction
3. Deep DiveClinical Dilemma #1 - How long should I anticoagulate for a PE before doing a time-sensitive liver biopsy?
   • For patients with proximal DVT, the risk of having a recurrence or progression of the DVT or PE without anticoagulation in the first 30 days is about 50% from a
   • Within the first month of being on anticoagulation for DVT you get fibrinolysis and endothelialization so theoretically after 1 month there should be decreased risk of embolization
   • A showed that there was decreased VTE recurrence with 6 months as opposed to 6 weeks of anticoagulation
4. Deep DiveClinical Dilemma #2 - The patient returns with progression of her PE after only 3 days off of anticoagulation. What went wrong here?
   • The looked at holding DOACs prior to surgery in patients with AF and showed that holding the DOAC for 48h was associated with low stroke and low bleeding risk, but that’s all the data that we have for holding DOACs periop that we’re aware of
   • In the trial of apixaban vs low molecular weight heparin (need to find this trial) for cancer associated thrombosis 0.7% of the patients on apixaban had a recurrent clot in the first 6 months while they were still on the drug. And it was even higher for low molecular weight heparin.
5. Deep DiveClinical Dilemma #3 - Should we place an IVC filter to prevent further embolization of her DVT
   • The trial compared anticoagulation alone to anticoagulation plus IVC filter and showed no difference in mortality
   • The trial also compared anticoagulation alone to anticoagulation plus IVC filter but looked symptomatic PE and there was also no difference
   • Both trials found an increased rate of DVT in the IVC filter group
6. Deep DiveClinical Dilemma #4- When should we do a liver biopsy in a patient with an active clot who has failed outpatient interruption of anticoagulation?
   • There are that are used to estimate patient bleeding risk and procedure bleeding risk to decide what best to do with a patient’s anticoagulation
7. Case Conclusion and Reflections

CME Credit

This activity has been planned and implemented in accordance with the accreditation requirements and policies of the Accreditation Council for Continuing Medical Education (ACCME) through the joint providership of the »Æ¹ÏµÎµÎapp (ACP) and Core IM. The »Æ¹ÏµÎµÎapp is accredited by the ACCME to provide continuing medical education for physicians.

The ACP designates this enduring material for .5 AMA PRA Category 1 credit ^TM.   Physicians should claim only the credit commensurate with the extent of their participation in the activity.

ABIM Maintenance of Certification (MOC) Points

Successful completion of this CME activity, which includes participation in the evaluation component, enables the participant to earn up to .5 medical knowledge MOC Point in the American Board of Internal Medicine’s (ABIM) Maintenance of Certification (MOC) program.  Participants will earn MOC points equivalent to the amount of CME credits claimed for the activity. It is the CME activity provider’s responsibility to submit participant completion information to ACCME for the purpose of granting ABIM MOC credit.

How to Claim CME Credit and MOC Points

After listening to the podcast, complete a brief multiple-choice question quiz. To claim CME credit and MOC points you must achieve a minimum passing score of 66%. You may take the quiz multiple times to achieve a passing score.
