(Lifespan) A new study from Rhode Island Hospital shows that guidelines concerning testing patients for possible community-acquired pneumonia due to Legionella may underestimate the number of cases being seen by clinicians.
The study found that if testing was only done in patients felt to be at increased risk of Legionnaires' disease based on such guidelines, more than 40 percent of Legionella cases could be missed based on this single-center study.
