Choosing Wisely's five top "no-no's" in critical care

Choosing Wisely is an initiative of the American Board of Internal Medicine (ABIM) with the stated goal of “promoting conversations between physicians and patients by helping patients choose care that is supported by evidence, not duplicative, free from harm, and truly necessary.” Sounds good, huh? Politically, ABIM’s Choosing Wisely seeks to demonstrate to policymakers responsible [... read more]

US Gov't pronounces lung cancer screening the standard of care

It’s official: the U.S. Preventive Services Task Force (USPSTF) announced its formal recommendation for yearly low-dose chest CT screening for lung cancer in high-risk individuals on December 30, 2013. The final grade B recommendation (“Suggestion: offer or provide this service”) was virtually unchanged from the draft recommendations the USPSTF made in July 2013. It advises [... read more]

Overdiagnosis rate with lung cancer screening CT is 18%

Low-dose CT screening reduced death from lung cancer by about 20% in the National Lung Screening Trial, and the U.S. Preventive Services Task Force signaled it would recommend CT screening for most people with a heavy smoking history. The Affordable Care Act stipulates that USPSTF-recommended screening tests be completely free to consumers, so lung cancer screening will [... read more]

"Choosing Wisely" campaign targets pulmonary hypertension drugs' off-label use

Choosing Wisely, the initiative for medical cost-effectiveness (don’t call it rationing!) of the American Board of Internal Medicine, included the use of vasodilators for pulmonary hypertension owing to left heart disease or hypoxemic lung disease (WHO Groups II and III) as #2 on its top five “no-no’s” in its new pulmonology section. The “Five Things Physicians and [... read more]

USPSTF Recommends Lung Cancer Screening CT; Obamacare Pays

USPSTF Endorses Lung Cancer Screening CT; New Standard of Care Begins Lung cancer screening CT took its most important step toward widespread implementation last week, when the U.S. Preventive Services Task Force (USPSTF) released a draft of its forthcoming recommendation that the 9 million U.S. people meeting entry criteria for the National Lung Screening Trial [... read more]

How to ration lung cancer screening CTs, rationally

Restrict Lung Cancer Screening CT To Highest-Risk People? The National Lung Screening Trial showed that 3 annual low-dose chest CT scans in people with heavy smoking histories (30+ pack-years) saved lives, reducing the risk of death from lung cancer by a relative 20% compared to screening with annual chest X-rays. With 160,000 lung cancer deaths [... read more]

How safe is EBUS? Complication rates <1% at experienced centers

image: Olympus EBUS Complication Rates <1% at Experienced Centers Endobronchial ultrasound (EBUS) — an ultrasound probe on the tip of a bronchoscope — allows real-time viewing of tissues beyond the bronchial wall. It enables more accurate and safer needle biopsies of lymph nodes and masses that abut the bronchial wall. EBUS is an exciting new [... read more]

Inferior vena cava filters: debatable benefit; rarely removed

image: Wikimedia Inferior Vena Cava Filters: What’s the Harm? Do inferior vena cava filters actually create more harm than health? That’s the provocative question being posed by authors and editorialists in JAMA Internal Medicine. Inferior vena cava filters are frequently placed after a pulmonary embolism (PE) or deep venous thrombosis (DVT) in patients with a [... read more]

Forget "embolic burden" of pulmonary embolism: location is everything

In Most Patients with Pulmonary Embolism, Central Clot is Worse than Peripheral by Brett Ley, MD Pulmonary embolism (PE) presents with a wide range of clinical severity and course. Management decisions (level of care, length of observation, and aggressive therapies such as thrombolysis) are generally based on a patient’s risk of a poor outcome. Guidelines recommend risk [... read more]

PET scans often inaccurate; may deny curative surgery for lung cancer

The use of positron emission tomography — better known as PET scans — has grown dramatically over the past 15 years, thanks to their seemingly magical ability to identify foci of undetected metastatic cancer. But PET scans’ perceived high accuracy in diagnosing metastatic non-small cell lung cancer (NSCLC) — a published 94% sensitivity and 83% [... read more]

ACCP, ATS only weakly recommend lung cancer CT screening, warn of harms

The American College of Chest Physicians (ACCP) has issued its long-awaited recommendations on lung cancer screening with chest CT — and far from a ringing endorsement of screening, they are conservative and subdued, emphasizing the potential risks of an uncontrolled approach to lung cancer screening in the general population. The American Society of Clinical Oncology [... read more]

American Lung Association recommends CT screening for lung cancer

The American Lung Association has become the largest advisory body to recommend lung cancer screening for high-risk people, advising nearly all people aged 55-74 with a 30+ pack-year smoking history (the entry criteria for the National Lung Screening Trial, or NLST) to undergo low-dose CT scanning to detect early lung cancer. The National Comprehensive Cancer Network, [... read more]
