There has been a slight decrease in the number of hospital-acquired infections reported across California. According to data was recently released by the California Department of Public Health, there was a drop in the number of healthcare infections reported in the state between 2011 and 2012.

California hospitals saw a 5% decline in the number of central line -associated bloodstream infections that occurred during this period of time. There was also a 6% drop in the number of methicillin resistant Staphylococcus aureus or MRSA bloodstream infections during the same period of time. The drops in these infections are especially significant because they happen to be some of the deadliest and most difficult-to-treat infections recorded in California hospitals.

Central line-associated bloodstream infections are some of the deadliest infections, and usually occur due to contamination of the central lines that are often used to deliver nutrition and drugs to a patient in an intensive care unit. When these lines are contaminated due to improper handling, improper use of catheters, failure to wash hands before attending to a patient in the ICU and other causes, it can result in a deadly infection that is swiftly transmitted to the patient. Since drugs and nutrients are directly transferred into the patient's bloodstream via central lines, the infectious bacteria is also transmitted super quickly as well. MRSA infections are some of the most resistant infections and are resistant to most antibiotics are used to treat hospital-acquired infections.

There has also been a decline in the number of hospitals that reported vancomycin -resistant enterococcus bloodstream infections. In 2012, out of the 386 hospitals that reported data on these deadly infections, 54% reported no such infection in 2012. However, in 2011, the number of hospitals that reported no vancomycin -resistant enterococcus bloodstream infections was just about 48%.
