For years, we’ve known about the cesspool of germs, diseases, and bacteria that line hospital halls, but two new reports are shedding more light on the dirty truth.

The Centers for Disease Control and Prevention (CDC) issued a progress report on infections contracted during hospital stays. Efforts have been in action by agencies such as the Health and Human Services Department and the Centers for Medicare and Medicaid Services to decrease hospital-acquired infections, but the CDC findings show that more still needs to be done for patient safety.

The study shows a 50 percent decrease in central line-associated bloodstream infections between 2008 and 2014, but there was only an 11 percent drop in catheter-associated urinary tract infections between 2009 and 2013.
