Antibiotic Resistance

1. This data portal presents antimicrobial resistance testing data from select healthcare-associated infections (CLABSI, CAUTI, and SSI) in U.S. hospitals. Other types of infections or asymptomatic carriage with antibiotic resistant organisms are not addressed in the portal. The data were reported into CDC’s National Healthcare Safety Network and are based on routine testing performed and reported by U.S. hospital laboratories. As such, testing or reporting errors may be included. More information on the methodology, data collection, and limitations can be found in the Antibiotic Resistance Data Methodology paper.

2. Data presented in the portal are not representative of the entire U.S. patient population and may vary by state and year. Data presented include but are not limited to facilities reporting through participation in the Centers for Medicare and Medicaid Services (CMS) Inpatient Quality Reporting Program, which started in 2011. However, individual states may have additional reporting requirements (e.g., State A may require reporting of SSIs from hip prosthesis while State B may not). Therefore caution should be used when making direct comparisons of percent resistance or number of resistant infections between states. The data shown in portal do not change clinical recommendations previously made by CDC but could be used by researchers, health departments, and facilities to help generate infection control priorities.

3. These 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, 2019 (AR Threat Report). The percent resistance describes the proportion of all pathogens that are resistant to certain antibiotics. Percentages shown in the portal may not reflect the total burden of healthcare-associated infections. For example, State A has a higher percentage of MRSA (48.0%) among all years and HAI’s compared to State B (46.0%), however State B had more MRSA infections (1393) than State A (20). For an estimate of total burden of disease, please see the AR Threat Report.

Hospital Antibiotic Stewardship

1. Denominator data include all inpatient acute care facilities, with the exception of inpatient psychiatric hospitals, long-term acute care hospitals, and inpatient rehabilitation facilities.

2. To maintain hospital anonymity, data are not shown for states, territories, or military postings with 7 or fewer total survey respondents. The following U.S. territories are not represented in results shown here: Armed Forces Europe (AE), Armed Forces Pacific (AP), American Samoa (AS), Guam (GU), Northern Mariana Islands (MP), Virgin Islands (VI).
