The Spread Of Antibiotic Bacteria Can Be Restrained Through Patient Registries

A new study by researchers at the Johns Hopkins Bloomberg School of Public Health reveals that the spread of carbapenem-resistant enterobacteria (CREs) bacteria with a high degree of opposition to most antibiotics could be dropped. This is possible if only 25% of larger health units utilize patient registry, which used as a database whose patients with CREs.

The Centers for Disease Control and Prevention (CDC) estimate that around 2 Million people get infected to an antibiotic-resistant bacterium every year, resulting in 23,000 deaths at least. Antibiotic-resistant bacteria, which do not react to many diverse treatments, can spread rapidly in health facilities as hospital staff and doctors may not know which patients, including new ones, have entered the facility.

For the study, the team developed a detailed computer simulation model of all 462 health facilities, with a population of 9.9 million in the Chicago metropolitan area. The study area comprised parts of Indiana, Illinois, Wisconsin. The model included virtual representations of patients and imitated their movements amid their communities and different health units, as well as within each health institution. Every virtual patient can use CRE or not use it.

The researchers found that when 25% of the largest healthcare institutions used a register with 60% of NCE operators, after three years there were 9.1% fewer new operators in the region. With the participation of all 402 health units in Illinois, the registry reduced the number of new CRE patients by 11.7% and the prevalence by 7.6% in three years. When half of Illinois health institutions participated, the registry reduced the number of new CRE  patients by 10.7% and the prevalence by 5.6% in three years.

Recognizing patient carrying CRE through the CRE can help save time and resources, specifically, if carriers don’t require to be reidentified, said co-author and MPH, faculty at the GOPC, Sarah M. Bartsch.
