Abstract

Background and objectives: Bundled interventions and auditing have been recommended to reduce central line-associated bloodstream infection (CLABSI) events at acute care hospitals. We review the outcomes of a bundle audit program at an adult and pediatric academic medical center from April 1, 2021, to May 31, 2022. To analyze the impact on CLABSI rates following the introduction of a central line maintenance bundle audit process.

Methods: All audit survey data, CLABSI event rates, and line days were collected. Statistical relationships were evaluated for CLABSI bundle performance with CLABSI rates and audit volume with CLABSI rates. Analyses were conducted at the hospital and unit level.

Results: No correlation is found between CLABSI rates and audit performance at the hospital level (adult units, P = .619, r-sq = 2.13%; peds/NICU, P = .825, r-sq = 0.43%) or at the unit level (n = 7; P = .8-.896, r-sq = 0.15%-18.2%). There was no correlation in CLABSI rates when reviewing performance by audit volume at the hospital level (adult, P = .65, r-sq = 1.7%; peds/NICU, P = .677, r-sq = 1.5%) or at the unit level (n = 7; P = .25-.8, r-sq = 1.2%-8.5%). By contrast, a single unit that did not participate in the audit program during the sample period reported a lower CLABSI rate than comparable participating units ( P = .008).

Conclusion: During the sample period, there was no relationship found between this CLABSI bundle audit program and improvement in CLABSI performance.
