Limited cancer screening seems appropriate after unprovoked PE

Cancers can cause pulmonary embolism, and an unprovoked PE may signal an undiscovered cancer lurking in the body. In older studies, as many as 1 in 10 patients with unprovoked PE were diagnosed with cancer within a year. (The current terminology is that a PE is provoked if associated with a known cancer or another provoking factor, but [… read more]

Dabigatran-induced bleeding: antidote (idarucizumab) on the way

New oral anticoagulants like dabigatran, apixaban and rivaroxaban have advantages over warfarin: not requiring regular monitoring for efficacy; faster onset of action; shorter half-lives. Unlike warfarin, they’ve had the significant disadvantage of having no proven antidote for the bleeding that inevitably occurs when any anticoagulant is given to thousands of people.

Are central lines really needed for vasopressor infusions?

image: Wikipedia There’s only one sure way to prevent complications from a central line: don’t place one. Like many invasive interventions, some of central venous catheters’ indications have been called into question in recent years. Monitoring of central venous pressure and central venous oxygen saturation via central IV access — once considered essential to good care [… read more]

Recurrent PE risk after long-term warfarin therapy remains high (PADIS-PE)

Not long ago, doctors were taught that 6 months of anticoagulation was plenty for patients with unprovoked pulmonary embolism. That standard was never based on long-term outcomes studies. And as longer-range data started to come in — gulp — it was clear that large numbers of people treated with 6-month warfarin courses after unprovoked PE [… read more]

Bridging anticoagulation for procedures after DVT/PE: usually, more harm than help?

“Bridging” anticoagulation — usually, interrupting chronic warfarin therapy, starting injectable or intravenous heparin, stopping just before an invasive procedure, restarting heparin and warfarin after, then stopping heparin — is a cumbersome and common practice in medicine. A new paper in JAMA Internal Medicine suggests that for most patients taking anticoagulation after deep venous thrombosis (DVT) [… read more]

Medicare will pay for death panels, I mean end-of-life counseling

Medicare announced last week it will finally pay doctors for their time spent talking to patients about their end-of-life preferences, among the most important medical decisions most people will make. The decision overcomes years of setbacks brought about by Sarah Palin’s politicizing of the Affordable Care Act’s provision for end-of-life counseling as endorsing “death panels” of [… read more]

Direct thrombin inhibitors associated with heart attack risk in multiple trials

Direct thrombin inhibitors (DTIs) are anticoagulants (blood thinners) most often used as alternatives to heparin and warfarin. DTIs are approved by the FDA for prevention and treatment of venous thromboembolism (deep venous thrombosis and pulmonary embolism) and to prevent blood clots in people with atrial fibrillation. But multiple randomized trials suggest these widely used anticoagulants might cause heart [… read more]

Families stall end of life talks, say doctors. True?

Doctors and nurses said patients and their families created the largest obstacles to end-of-life decision making in the ICU, in a large survey published in JAMA Internal Medicine. About 1,300 staff at 13 academic hospitals in Canada rated barriers to end-of-life goals of care on a 1-7 scale. Doctors and nurses considered the largest barriers [… read more]

Restricting calories by 50% during critical illness results in no harm

Everyone agrees that providing adequate nutrition in critical illness is vitally important. The problem is, no one knows for sure what “adequate” means. Caloric targets are not based on evidence from randomized trials with meaningful clinical outcomes. They emerge as consensus from educated guesses by researchers conducting physiology studies. One camp believes that extra calories should [… read more]

High flow oxygen by nasal cannula saves lives over noninvasive ventilation

Image: F&P Healthcare Noninvasive ventilation (NIV), often referred to by the trade name “BiPAP®,” can prevent intubation and save lives in patients with COPD exacerbations or pulmonary edema due to heart failure. Its proven benefits and low risk have led to NIV being used for patients in respiratory failure in virtually every acute care setting [… read more]
