New HAI Statistics
The CDC has released new information and statistics on the prevalence of health care-associated infections, or HAIs.
Nationally, among acute care hospitals, there was a 1-13% statistically-significant decrease in specific HAI types between 2016 and 2017. The CDC previously reported that 1 in 25 patients will contract an HAI; however, that has been reduced to 1 in 31 patients. Further, there were an estimated 687,000 HAIs in U.S. acute care hospitals in 2015, and about 72,000 hospital patients with HAIs died during their hospitalizations. That number is also down from the previously reported 700,000 HAIs and 75,000 patient fatalities.
While C. diff decreased by 13% and MRSA by 8% in 2017, HAIs remain the most common form of preventable hospital complication, affecting hundreds of thousands of patients each year.
In 2014, a total of 14.2 million operative procedures were performed in the inpatient setting in U.S. hospitals. A recent prevalence study found that SSIs were the most common healthcare-associated infection (HAI), accounting for 31% of all HAIs among hospitalized patients. The CDC HAI prevalence survey found that there were an estimated 157,500 surgical site infections associated with inpatient surgeries in 2011. Further, SSIs are the costliest HAI type with an estimated annual cost of $3.3 billion and are associated with nearly 1 million additional inpatient days annually.
While it is good news that HAIs are on the decline, there is still much work to do to eradicate these preventable infections.
The BETR-D study showed that enhanced terminal room disinfection strategies using Tru-D decreased the relative risk of colonization and infection of target MDROs among patients admitted to the same room by a cumulative 30% in a hospital setting with 93% compliance of standard disinfection protocols. Individual hospital results may vary.
