Hospital-Acquired Infection (HAI) Rates in New York State Hospitals

Hospital-acquired infections (HAIs) are a significant cause of morbidity and mortality, affecting approximately four percent of inpatients1. A CDC report estimated the annual medical costs of healthcare-associated infections to U.S. hospitals to be between $28 and $45 billion dollars.2

In July, 2005, the Legislature passed and the Governor signed Public Health Law 2819 requiring hospitals to report select HAIs to the New York State Department of Health. This law was created to provide the public with fair, accurate, and reliable HAI data to compare hospital infection rates and to support quality improvement and infection prevention activities in hospitals. Annual reports that summarize hospital HAI rates are published on this website each year. The data are also available for download on Health Data NY, the Department's open data portal.

The eighth annual report entitled "Hospital-Acquired Infections - New York State 2014" (PDF, 5.7MB) provides hospital-acquired infection rates statewide and by individual hospital for 2014. The infections selected for reporting in 2014 include colon surgical site infections, hip replacement surgical site infections, coronary artery bypass graft surgical site infections, abdominal hysterectomy surgical site infections, central line-associated bloodstream infections in intensive care units (adult, pediatric and neonatal intensive care units), and Clostridium difficile and carbapenem-resistant Enterobacteriaceae infection rates occurring on admission and during a patient's hospital stay. The report also describes progress of HAI prevention projects supported by the Department.
