Common CLABSI Rates Per 1,000 Catheter Days
CLABSI rates vary significantly by patient population and setting, ranging from approximately 2.9 per 1,000 catheter days in well-resourced adult ICUs to as high as 11.3 per 1,000 catheter days in high-risk neonatal populations, though prevention-focused protocols can reduce rates to less than 1 per 1,000 catheter days. 1
Adult ICU Populations
The most comprehensive benchmark data comes from CDC's National Nosocomial Infection Surveillance System (NNIS), which tracked rates across nearly 300 U.S. hospitals from 1992-2001. Adult ICU CLABSI rates ranged from 2.9 to 7.9 per 1,000 catheter days depending on the specific ICU type 2:
- Cardiothoracic ICU: 2.9 per 1,000 catheter days (lowest adult rate)
- Coronary ICU: 4.5 per 1,000 catheter days
- Medical ICU: 5.9 per 1,000 catheter days
- Medical/Surgical ICU: 5.3 per 1,000 catheter days
- Surgical ICU: 5.3 per 1,000 catheter days
- Pediatric ICU: 7.6 per 1,000 catheter days
- Trauma ICU: 7.9 per 1,000 catheter days
- Burn ICU: 9.7 per 1,000 catheter days
More recent data from 2023-2024 shows an overall incidence of 0.507 per 1,000 catheter days in a tertiary care hospital setting 3, while another contemporary study reported 8.91 per 1,000 catheter days in Palestinian ICUs 4, and 13.70 per 1,000 catheter days in an Indian tertiary care hospital 5. This wide variation reflects differences in prevention protocols, patient populations, and resource availability.
Pediatric and Neonatal Populations
Pediatric CLABSI rates are consistently higher than adult rates and show dramatic variation based on birth weight and resource setting 6:
Neonatal ICU (NICU) Rates by Birth Weight:
- <1,000 g: 11.3 per 1,000 catheter days (highest risk group)
- 1,001-1,500 g: 6.9 per 1,000 catheter days
- 1,501-2,500 g: 4.0 per 1,000 catheter days
- >2,500 g: 3.8 per 1,000 catheter days
Geographic Variation in NICUs:
- USA NICUs: 2.9 per 1,000 catheter days
- Limited-resource countries: 2.6 to 60 per 1,000 catheter days 6
A recent Swiss neonatal study (2020-2023) reported an overall rate of 2.9 per 1,000 catheter days, but this varied dramatically by catheter type 7:
- Umbilical artery catheters (UACs): 0 per 1,000 catheter days
- Peripherally inserted central lines (PICCs): 0.9 per 1,000 catheter days
- Umbilical venous catheters (UVCs): 5.6 per 1,000 catheter days
- Centrally inserted venous catheters (CVCs): 17.9 per 1,000 catheter days
Specialized Populations
Pediatric Intestinal Failure/Home Parenteral Nutrition:
Children with intestinal failure on parenteral nutrition show rates of 3.8 to 11.3 per 1,000 catheter days, with a more specific range of 1.2 to 10.2 per 1,000 catheter days 1. Home parenteral nutrition patients demonstrate lower rates of 0.34 to 3.94 episodes per catheter year 1.
Recent data on adult home parenteral nutrition shows 0.91 episodes per 1,000 total catheter days overall, with significant variation by catheter type 8:
- Peripherally inserted catheters: 1.91 per 1,000 catheter days
- Tunneled catheters: 0.63 per 1,000 catheter days
- Implanted ports: 0 per 1,000 catheter days
Resource-Limited Settings:
A multinational study implementing prevention bundles in 30 countries across Africa, Asia, Latin America, Eastern Europe, and the Middle East documented a baseline CLABSI rate of 15.34 per 1,000 catheter days, which was successfully reduced to 2.23 per 1,000 catheter days over 29 months 9.
Achievable Targets with Prevention Protocols
The most important clinical takeaway is that prevention-focused protocols can reduce CLABSI rates to less than 1 per 1,000 catheter days 1. A Turkish pediatric study demonstrated reduction from a baseline of 10.5 to 3.6 per 1,000 catheter days following bundle implementation 9. Meta-analyses show that care bundles can achieve a 60% reduction in CLABSI rates (rate ratio = 0.40, CI 0.31 to 0.51) 6.
Critical Clinical Context
These rates carry substantial clinical significance beyond mere statistics. CLABSI mortality in neonates reaches 21%, with infections increasing length of stay by 23 days and causing significant neurodevelopmental impairment risk in very low birth-weight infants 6. In adult populations, a 2023-2024 study found CLABSI significantly prolonged hospitalization by 20 days, increased mortality risk by 88%, and elevated direct medical costs by $13,962 3.
The goal for any institution should be elimination of CLABSI, with sustained rates below 1 per 1,000 catheter days as an achievable benchmark through rigorous adherence to insertion and maintenance bundles 1, 10.
