The study, published online on June 28 in the journal PLOS ONE, found that people who were more likely to use novel antibiotics were more costly to treat.
The researchers found that the higher the antibiotic usage, the more expensive the treatment.
The authors also noted that the increase in costs could be attributed to a “high proportion of novel antibiotics used by patients,” and noted that antibiotic use increased in the first half of the 21st century, and has since increased again.
The study is the first to look at antibiotic usage trends in U.S. hospitals, a health care sector that has become a hotbed of antibiotic resistance.
It also comes at a time when the U.N. Office for Drugs and Crime is warning of a new trend in antibiotic resistance: The use of novel antibiotic drugs to treat infections in people with infections, including in infants and children.
The new drug use trend has led to a doubling of antibiotic-resistant infections since the year 2000, the agency reported last week.
The drug resistant bacteria are spreading rapidly across the U
