Incorporating clinical-decision support into electronic health records can help mitigate the use of antibiotics, according to researchers presenting at the Infectious Diseases Society of America.
Drug-resistant bacteria are increasing, and there are not enough new drugs being developed to counteract methicillin-resistant Staphylococcus aureus infections or other infections caused by Clostridium difficile, the IDSA said during its 47th annual conference in Philadelphia.
Researchers studied the effect of EHRs and computerized physician order-entry systems implemented at 739-bed Pitt County Memorial Hospital, Greenville, N.C., in 2007 on the use of anti-microbial agents associated with a high risk of causing Clostridium difficile infections. The study measured on a quarterly basis the 46 commonly prescribed antibiotics as well as the cases of Clostridium difficile infections per 1,000 hospital patient days for 10 quarters before EHR implementation and six quarters after.
There was an 18% decrease in the use of all anti-microbials and a 26.2% decrease in the rate of infection after the computer system was implemented, according to the researchers. The results were presented during a session on healthcare-related infections.
