CDC's Antibiotic Resistance Patient Safety Atlas

CDC's Antibiotic Resistance Patient Safety Atlas provides open and interactive data about healthcare-associated infections (HAIs) caused by antibiotic resistant bacteria, which are reported to CDC through the National Healthcare Safety Network (NHSN).

Interactive Maps and Customizable Data

You can customize maps and tables to show antibiotic resistance patterns in HAIs by filtering the data by geographical area (national, regional, and state), time period, event type, and patient age.

About the Data*

The AR Atlas includes 2011-2014 data reported to CDC’s National Healthcare Safety Network.

Data Sources

The data is from 4,403 facilities that reported at least one HAI to NHSN, including:

3,676 acute care hospitals
506 long-term acute care hospitals
221 inpatient rehabilitation facilities

Due to insufficient data, long-term care and skilled nursing facilities are not included at this time.

Event Types

The data shown in the AR Atlas were gathered after one of three key types of infections occurred in the hospital:

Central line-associated bloodstream infections (CLABSI)
Catheter-associated urinary tract infections (CAUTI)
Surgical site infections (SSI)**

**At the national level, SSI data reflect all types of SSIs (superficial, deep, and organ/space) that occurred following any of the 39 NHSN inpatient procedures and were performed between 2011-2014.

Pathogens Included

The AR Atlas includes resistance data for 31 bug-drug profiles (or phenotypes, pathogen-antibiotic combinations that are used to describe the bacteria’s resistance to a specific drug(s)). These phenotypes include:

Methicillin-resistant Staphylococcus aureus (MRSA)
Carbapenem-resistant Enterobacteriaceae (CRE)
Multidrug-resistant Pseudomonas aeruginosa

For a full list of pathogen-drug combinations, read the Phenotype Definitions document[PDF - 180 KB].

*To read how the data were gathered and limitations of the data, please read the Methodology document[PDF - 123 KB]. The AR Atlas data help inform, but do not replace, national estimates of cases of infection in the U.S. reported by CDC in the Antibiotic Resistance Threats in the United States, 2013 (AR Threat Report). The AR Threat Report published in 2013 used NHSN data from 2010-2012 in combination with other national surveillance and prevalence survey data to extrapolate estimates. CDC will perform such extrapolations periodically to update the AR Threat Report, which will remain a separate initiative from this Atlas.
