Hospital and EMS partnerships allows us to be the best stewards of the nation’s precious O red cell resources, so we can ensure patients needing blood both inside and outside the hospital have access!

Today we announced an innovative program with the Genesee County Sheriff's Office that helps ensure lifesaving blood is available when and where it's needed - before a patient reaches the hospital. Read more: https://t.co/xnBCg4NO9H

Every 15 seconds someone in the U.S. needs platelets. Platelets must be used within 5 days of donation. That means the need is constant! More platelet donors are needed to help the millions of Americans who need platelets every year for survival. Get info: https://t.co/sSKQkaa5kL

Prehospital transfusion saves lives, but optimal strategies remain unclear.

The SWiFT trial, published in @NEJM, found no survival or massive transfusion advantage to whole blood versus component therapy in severe trauma.

Phenomenal talk on a key patient population that would benefit from more nuanced care at the @HopkinsMedicine VTE symposium today. "Sickle cell anemia is a high-risk thrombophilia: implications for VTE prevention in pregnancy." #BCAM #JHMVTE @elliotthaut @LauzeeTweet @mstreif1

Whole blood resuscitation is well studied in trauma. But what about non-trauma hemorrhage?

Researchers from @WakeForestMed examined 331 patients. The findings suggest whole blood can be safely used in severely hemorrhaging non-trauma patients.

Diabetes impacts 38M+ people in the U.S. & nearly 25% don't know they have it. Successful blood, platelet & plasma donations in March get free A1C testing (diabetes screen; 1 result in 2026). Get valuable insight into your health & help save lives: https://t.co/HhtdMFt8g4

Apixaban and rivaroxaban are the most frequently used oral anticoagulants for acute venous thromboembolism, but data on the difference in bleeding risk between the drugs are lacking. Research findings from the COBRRA trial are summarized in a new Quick Take video. https://t.co/aRRnnWmU34

It's #PatientSafetyAwarenessWeek and we are loving the creative ways our @HopkinsMedicine colleagues are recognizing the occasion, demonstrating their commitment, and spreading the word. Check out "Zero Harm Fest" from the team at @allchildrens!

[NEJM @NEJM]

In an international, randomized trial involving patients with acute venous thromboembolism, the risk of clinically relevant bleeding was significantly lower with apixaban than with rivaroxaban during the 3-month treatment period.

🚨 New head-to-head RCT in @NEJM: apixaban vs rivaroxaban 🥊

🏆 Apixaban emerges as the safe winner, with half the risk of bleeding complications

💡 For patients at high risk of GI bleeding, apixaban may be preferrable to rivaroxaban

Do I ever plan to steer a boat?
Nope. 🙂‍↔️
Am I still taking notes?
💯

[Virginia Department of Emergency Management @VDEM]

For boaters, getting too close can turn deadly in seconds.

🚤 If you see a waterspout, steer clear and give it plenty of distance. Don’t chase it, don’t film it up close, and definitely don’t test how close you can get.

New in #Transfusion:

A survey of inpatient providers at @UChicagoHospMed explores which factors clinicians prioritize when deciding whether to transfuse. Five of the seven top-ranked factors were hemoglobin-related.

As a post-2022 Teams user, I had no idea there was a time before the raising of hands. I am intrigued by this level of potential chaos. 🤠

[Delphine Govender @Delphine_DG]

Dear @MicrosoftTeams please please can we have a “raise hand” 🖐🏾 feature or equivalent in group calls?! So necessary. Please and thank you in advance.
