Hospitalized patients in the United States faced a lower risk of healthcare-associated infections (HAIs) in 2023 compared to 2015, according to new data from the Centers for Disease Control and Prevention (CDC). While roughly 1 in 38 patients contracted an infection in 2023, the rate improved from 1 in 31 patients in 2015, signaling progress in hospital safety protocols.
Trends in Hospital Infection Rates
The CDC’s latest survey, conducted through its Emerging Infections Program, involved 13,653 patients across 218 hospitals in 10 states. By reviewing medical records against National Healthcare Safety Network definitions, researchers determined that patients in 2023 were statistically less likely to experience an HAI than those in the 2015 cohort, even when adjusting for differences in patient populations.
Specific categories of infections showed marked improvement. The data highlights significant reductions in:
- Central line-associated bloodstream infections
- Catheter-associated urinary tract infections
- Clostridioides difficile (C. diff) infections
These improvements align with national prevention initiatives and enhanced infection control practices adopted by healthcare facilities.
Persistent Challenges in Patient Safety
Despite these gains, HAIs remain a significant public health burden. In 2023, an estimated 518,000 HAIs occurred within U.S. hospitals. These infections continue to pose serious risks to patient outcomes and contribute to substantial healthcare costs.
Data analysis reveals that 61% of all recorded HAIs were not linked to specific medical devices or procedures, suggesting that broader environmental and transmission-based precautions remain critical. Furthermore, some areas of care have not seen the same level of progress as others. Rates of pneumonia and surgical site infections remained largely unchanged between the two survey periods, indicating a need for more effective, targeted prevention strategies for these specific conditions.
Federal Oversight and Quality Initiatives
The reduction in infection rates is attributed in part to collaborative efforts between the CDC and the Centers for Medicare & Medicaid Services (CMS). These agencies utilize the National Healthcare Safety Network to facilitate quality reporting, benchmarking, and national transparency.
The CDC’s Division of Healthcare Quality Promotion has provided funding and technical support to every U.S. state, working alongside professional organizations and patient advocacy groups to optimize antibiotic use and improve clinical hygiene. Simultaneously, CMS has engaged its national Quality Improvement Organization networks to assist hospitals in implementing safer care standards.
These findings were formally published in The New England Journal of Medicine, providing a benchmark for clinicians and policymakers to refine future infection prevention protocols. While the decline in certain infection types is promising, federal health officials maintain that eliminating preventable harm remains a priority for the U.S. healthcare system.
