Experts Recommend Fewer Tests for Hospitalized Patients

Routine daily laboratory testing of hospitalized patients reflects a wasteful clinical practice that threatens the value of health care. Initiatives from numerous professional societies have identified repetitive laboratory testing in the face of clinical stability as low value care. More...

Fecal Hemoglobin Stability Evaluated for FITs

Screening with guaiac-based fecal occult blood tests (gFOBT), followed by colonoscopy for patients who test positive, has been associated with a reduction of 15% to 33% in colorectal cancer (CRC)–related mortality. More...

Risk Factors Identified for Duchenne Muscular Dystrophy-Associated Cardiomyopathy

Researchers have now identified important factors associated with death, thus highlighting a high‐risk DMD population with a worse cardiovascular and overall prognosis. More...

Ovarian Reserve Tests Prove Poor Predictors of Fertility

Tests that measure a woman’s “ovarian reserve” to estimate how many more years of fertility she has have grown increasingly popular, yet despite the lack of evidence of their utility, biomarkers of ovarian reserve are being promoted as potential markers of reproductive potential. More...

Low Serum Calcium Increases Risk of SCA

Sudden cardiac arrest (SCA) is fatal for over 90% of patients, and more than half of men and close to 70% of women who die of SCA have no clinical history of heart disease prior to this cardiac event. It is one of the leading causes of death in the USA and kills more people than any single cancer. More...

Renal Biomarker Test Prevents Acute Kidney Injury

Acute kidney injury (AKI) is a frequent complication among patients undergoing major surgery, and is known to increase morbidity, mortality risk, and costs. Although the complication can be managed, today’s standard indicators of AKI, such as elevated levels of serum creatinine, may not be present until kidney damage has already occurred. More...
