CDC’s National Healthcare Safety Network (NHSN), the nation’s most widely used HAI surveillance system, is a shared resource for HAI prevention. For more information, please visit CDC’s Healthcare-Associated Infection Data Reports website.ĬDC’s mission in healthcare safety includes tracking infections, responding to outbreaks, providing infection prevention expertise and guidance, implementing prevention interventions in collaboration with partners, spearheading prevention research, and serving as the nation’s gold standard microbiology laboratory for the pathogens most often implicated in HAIs. For detailed methods, references, and definitions, please refer to the Technical Appendix and Glossary within this report.

National and state HAI reports will be available for viewing, downloading, and printing from the Antibiotic Resistance and Patient Safety Portal. The report is designed to be accessible to many audiences. This report, along with the detailed technical tables, provides national- and state-level data about HAI incidence during 2021. To view HAI data from individual hospitals, LTACHs and IRFs, please see CMS Care CompareĪccess this report in the Antibiotic Resistance & Patient Safety Portal LTACHs provide treatment for patients who are generally very sick and stay, on average, more than 25 days. IRFs include hospitals, or part of a hospital, that provide intensive rehabilitation services using an interdisciplinary team approach. The designation of CAH is assigned by the Centers for Medicare and Medicaid Services (CMS) to hospitals with 25 or fewer acute care inpatient beds and that maintain an annual average length of stay of 96 hours or less for acute care patients. Data from CAHs are provided in the detailed technical tables but not in the report itself. The 2021 annual National and State Healthcare-Associated Infections (HAI) Progress Report provides a summary of select HAIs across four healthcare settings: acute care hospitals (ACHs), critical access hospitals (CAHs), inpatient rehabilitation facilities (IRFs) and long-term acute care hospitals (LTACHs). Preventing healthcare-associated infections (HAIs) is a top priority for CDC and its partners in public health and healthcare. The Centers for Disease Control and Prevention (CDC) is committed to protecting patients and healthcare personnel from adverse healthcare events and promoting safety, quality, and value in healthcare delivery.
