Central line-associated bloodstream infections (CLABSI), ubiquitous yet preventable hospital-acquired infections, contribute to significant morbidity and healthcare expenditure, necessitating rigorous scrutiny. Recently, a study has delved into the disparities in CLABSI outcomes based on variables such as race, ethnicity, and hospital attributes. This study used data from the National Inpatient Sample (NIS) database from 2016 to 2020 to compile a comprehensive patient cohort. It specifically focused on adult patients diagnosed with CLABSI and excluded those with primary CLABSI diagnoses, cancer, immune-compromised states, or neonatal conditions. The study primarily examined in-hospital mortality, length of stay, and hospital costs adjusted to mid-2020 U.S. dollars.
A significant finding of the study reveals approximately 19,835 CLABSI hospitalizations during the period from 2016 to 2020. With an overarching mortality rate of 9.1%, the median hospital stay and median cost were observed as 16.9 days and $44,810 respectively. A comparative analysis demonstrated that Hispanic patients bore higher mortality rates, longer hospital stays, and elevated costs than their non-Hispanic Black and White counterparts.
Several disparities were unearthed, for instance, urban teaching hospitals reported longer lengths of stay and increased costs than rural and urban non-teaching facilities, and geographically, the Northeast and West encountered higher costs and prolonged stays than the Midwest and South. However, the study found no significant difference in mortality rates across regions.
The study underscores the urgency to address these disparities in developing improved protocols for CLABSI management and ensuring healthcare equity. Furthermore, policies must adopt a targeted approach to understanding the underlying reasons causing these disparities and accordingly devise informed interventions.
Valuable light has been shed on CLABSI’s how their clinical and financial burden on healthcare system can be considerably mitigated through well-structured quality improvement initiatives aimed at addressing systemic factors like duration of catheterization, catheter type, and site of insertion, and standard of catheter care. However, patient-related risk factors, including medical conditions imposing health disparities, remain to be considerably attended.
The study also puts forth the difference in outcomes for CLABSI patients based on race/ethnicity, hospital location, and geographic regions in the U.S., unpacking various unexplored arenas in the journey towards health equity.
