Objective
To evaluate a central line care maintenance bundle to reduce central
line-associated bloodstream infection (CLABSI) in non-ICU settings.
Design
Before-after trial with 12 month follow-up period.
Setting
1250-bed teaching hospital.
Participants
Patients with central lines on eight general medicine wards. Four
wards received the intervention and four served as controls.
Intervention
A multifaceted catheter care maintenance bundle consisting of
educational programs for nurses, update of hospital policies, visual aids, a
competency assessment, process monitoring, regular progress reports, and
consolidation of supplies necessary for catheter maintenance.
Results
Data were collected for 25,542 catheter-days including 43 CLABSI
(rate = 1.68 per 1,000 CL-days) and 4,012 catheter dressing observations.
Following the intervention, a 2.5% monthly decrease in the CLABSI incidence
density was observed on intervention floors, but this was not statistically
significant (95% confidence interval (CI); −5.3 – 0.4). On
control floors, there was a smaller, but marginally significant decrease in
CLABSI incidence during the study (change in monthly rate = −1.1%;
95% CI, −2.1 - −0.1). Implementation of the bundle was
associated with improvement in catheter dressing compliance on intervention
wards (78.8% compliance pre-intervention vs. 87.9% during
intervention/follow-up; p<0.001) but improvement was also observed on
control wards (84.9% compliance pre-intervention vs. 90.9% during
intervention/follow-up; P = .001).
Conclusions
A multi-faceted program to improve catheter care was associated with
improvement in catheter dressing care, but no change in CLABSI rates.
Additional study is needed to determine strategies to prevent CLABSI in
non-ICU patients.
