Prevention of central line-associated bloodstream infections through quality improvement interventions: a systematic review and meta-analysis.

ABSTRACT: This systematic review and meta-analysis examines the impact of quality improvement interventions on central line-associated bloodstream infections in adult intensive care units. Studies were identified through Medline and manual searches (1995-June 2012). Random-effects meta-analysis obtained pooled odds ratios (ORs) and 95% confidence intervals (CIs). Meta-regression assessed the impact of bundle/checklist interventions and high baseline rates on intervention effect. Forty-one before-after studies identified an infection rate decrease (OR, 0.39 [95% CI, .33-.46]; P < .001). This effect was more pronounced for trials implementing a bundle or checklist approach (P = .03). Furthermore, meta-analysis of 6 interrupted time series studies revealed an infection rate reduction 3 months postintervention (OR, 0.30 [95% CI, .10-.88]; P = .03). There was no difference in infection rates between studies with low or high baseline rates (P = .18). These results suggest that quality improvement interventions contribute to the prevention of central line-associated bloodstream infections. Implementation of care bundles and checklists appears to yield stronger risk reductions.

Project description:ImportanceAlthough quality improvement (QI) interventions can reduce central-line-associated bloodstream infections (CLABSI) and catheter-related bloodstream infections (CRBSI), their economic value is uncertain.ObjectiveTo systematically review economic evaluations of QI interventions designed to prevent CLABSI and/or CRBSI in acute care hospitals.Evidence reviewA search of Ovid MEDLINE, Econlit, Centre for Reviews & Dissemination, New York Academy of Medicine's Grey Literature Report, Worldcat, prior systematic reviews (January 2004 to July 2016), and IDWeek conference abstracts (2013-2016), was conducted from 2013 to 2016. We included English-language studies of any design that evaluated organizational or structural changes to prevent CLABSI or CRBSI, and reported program and infection-related costs. Dual reviewers assessed study design, effectiveness, costs, and study quality. For each eligible study, we performed a cost-consequences analysis from the hospital perspective, estimating the incidence rate ratio (IRR) and incremental net savings. Unadjusted weighted regression analyses tested predictors of these measures, weighted by catheter-days per study per year.FindingsOf 505 articles, 15 unique studies were eligible, together representing data from 113 hospitals. Thirteen studies compared Agency for Healthcare Research and Quality-recommended practices with usual care, including 7 testing insertion checklists. Eleven studies were based on uncontrolled before-after designs, 1 on a randomized controlled trial, 1 on a time-series analysis, and 2 on modeled estimates. Overall, the weighted mean IRR was 0.43 (95% CI, 0.35-0.51) and incremental net savings were $1.85 million (95% CI, $1.30 million to $2.40 million) per hospital over 3 years (2015 US dollars). Each $100 000-increase in program cost was associated with $315 000 greater savings (95% CI, $166 000-$464 000; P < .001). Infections and net costs declined when hospitals already used checklists or had baseline infection rates of 1.7 to 3.7 per 1000 catheter-days. Study quality was not associated with effectiveness or costs.Conclusions and relevanceInterventions related to central venous catheters were, on average, associated with 57% fewer bloodstream infections and substantial savings to hospitals. Larger initial investments may be associated with greater savings. Although checklists are now widely used and infections have started to decline, additional improvements and savings can occur at hospitals that have not yet attained very low infection rates.

Project description:Importance:National Healthcare Safety Network methods for central line-associated bloodstream infection (CLABSI) surveillance do not account for potential additive risk for CLABSI associated with use of 2 central venous catheters (CVCs) at the same time (concurrent CVCs); facilities that serve patients requiring high acuity care with medically indicated concurrent CVC use likely disproportionally incur Centers for Medicare & Medicaid Services payment penalties for higher CLABSI rates. Objective:To quantify the risk for CLABSI associated with concurrent use of a second CVC. Design, Setting, and Participants:This retrospective cohort study included adult patients with 2 or more days with a CVC at 4 geographically separated general acute care hospitals in the Atlanta, Georgia, area that varied in size from 110 to 580 beds, from January 1, 2012, to December 31, 2017. Variables included clinical conditions, central line-days, and concurrent CVC use. Patients were propensity score-matched for likelihood of concurrence (limited to 2 CVCs), and conditional logistic regression modeling was performed to estimate the risk of CLABSI associated with concurrence. Episodes of CVC were categorized as low or high risk and single vs concurrent use to evaluate time to CLABSI with Cox proportional hazards regression models. Data were analyzed from January to June 2019. Exposures:Two CVCs present at the same time. Main Outcomes and Measures:Hospitalizations in which a patient developed a CLABSI, allowing estimation of patient risk for CLABSI and daily hazard for a CVC episode ending in CLABSI. Results:Among a total of 50?254 patients (median [interquartile range] age, 59 [45-69] years; 26?661 [53.1%] women), 64?575 CVCs were used and 647 CLABSIs were recorded. Concurrent CVC use was recorded in 6877 patients (13.7%); the most frequent indications for concurrent CVC use were nutrition (554 patients [14.1%]) or hemodialysis (1706 patients [43.4%]). In the propensity score-matched cohort, 74 of 3932 patients with concurrent CVC use (1.9%) developed CLABSI, compared with 81 of 7864 patients with single CVC use (1.0%). Having 2 CVCs for longer than two-thirds of a patient's CVC use duration was associated with increased likelihood of developing a CLABSI, adjusting for central line-days and comorbidities (adjusted risk ratio, 1.62; 95% CI, 1.10-2.33; P?=?.001). In survival analysis adjusting for sex, receipt of chemotherapy or total parenteral nutrition, and facility, compared with a single CVC, the daily hazard for 2 low-risk CVCs was 1.78 (95% CI, 1.35-2.34; P?<?.001), while the daily hazard for 1 low-risk and 1 high-risk CVC was 1.80 (95% CI, 1.42-2.28; P?<?.001), and the daily hazard for 2 high-risk CVCs was 1.78 (95% CI, 1.14-2.77; P?=?.01). Conclusions and Relevance:These findings suggest that concurrent CVC use is associated with nearly 2-fold the risk of CLABSI compared with use of a single low-risk CVC. Performance metrics for CLABSI should change to account for variations of this intrinsic patient risk among facilities to reduce biased comparisons and resultant penalties applied to facilities that are caring for more patients with medically indicated concurrent CVC use.
