Healthcare-Associated Infections

Healthcare-Associated Infections (HAIs) are among the leading causes of death in the United States. HAIs put the patient at risk, increase the days of hospitalization required for patients and add to healthcare costs. HAIs are largely preventable with widely publicized interventions, such as better hygiene and advanced scientifically tested techniques for surgical patients.

HAI measure data are collected by the Centers for Disease Control and Prevention (CDC) via the National Healthcare Safety Network (NHSN) tool. Hospitals must enroll and complete NHSN training to comply with the Centers for Medicare & Medicaid Services (CMS) Hospital Inpatient Quality Reporting (IQR) Program HAI requirements.

The CDC strongly recommends:

  • Multiple users complete the required NHSN training
  • Multiple users have access to the NHSN tool
  • Monthly data submission

CDC and CMS Joint Reminder on NHSN Reporting

CDC’s NHSN is the nation’s most comprehensive medical event tracking system and is currently utilized by more than 16,000 U.S. healthcare facilities. NHSN provides critical data to guide prevention efforts aimed at protecting patients.

CDC and CMS are committed to ensuring data accuracy and reliability for guiding prevention priorities and protecting patients. Identifying infections and making sure that patients receive the highest quality of care is our top priority.

In response to anecdotal reports of intentional non-reporting of infection data, CDC and CMS are jointly issuing a reminder that addresses concerns about healthcare facility non–reporting of healthcare-associated infections events. While there is no evidence of a widespread issue, CDC and CMS want to emphasize that accurate reporting to NHSN through strict adherence to the NHSN definitions is critical.
