The increased risks of death and extra lengths of hospital and ICU stay from hospital-acquired bloodstream infections: a case-control study.

ABSTRACT:

Objectives

Hospital-acquired bloodstream infections are known to increase the risk of death and prolong hospital stay, but precise estimates of these two important outcomes from well-designed studies are rare, particularly for non-intensive care unit (ICU) patients. We aimed to calculate accurate estimates, which are vital for estimating the economic costs of hospital-acquired bloodstream infections.

Design

Case-control study.

Setting

9 Australian public hospitals.

Participants

All the patients were admitted between 2005 and 2010.

Primary and secondary outcome measures

Risk of death and extra length of hospital stay associated with nosocomial infection.

Results

The greatest increase in the risk of death was for a bloodstream infection with methicillin-resistant Staphylococcus aureus (HR=4.6, 95% CI 2.7 to 7.6). This infection also had the longest extra length of stay to discharge in a standard bed (12.8 days, 95% CI 6.2 to 26.1 days). All the eight bloodstream infections increased the length of stay in the ICU, with longer stays for the patients who eventually died (mean increase 0.7-6.0 days) compared with those who were discharged (mean increase: 0.4-3.1 days). The three most common organisms associated with Gram-negative infection were Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumonia.

Conclusions

Bloodstream infections are associated with an increased risk of death and longer hospital stay. Avoiding infections could save lives and free up valuable bed days.

Project description:BackgroundChlorhexidine gluconate (CHG) bathing of hospitalized patients may have benefit in reducing hospital-acquired bloodstream infections (HABSIs). However, the magnitude of effect, implementation fidelity, and patient-centered outcomes are unclear. In this meta-analysis, we examined the effect of CHG bathing on prevention of HABSIs and assessed fidelity to implementation of this behavioral intervention.MethodsWe undertook a meta-analysis by searching Medline, EMBASE, CINAHL, Scopus, and Cochrane's CENTRAL registry from database inception through January 4, 2019 without language restrictions. We included randomized controlled trials, cluster randomized trials and quasi-experimental studies that evaluated the effect of CHG bathing versus a non-CHG comparator for prevention of HABSIs in any adult healthcare setting. Studies of pediatric patients, of pre-surgical CHG use, or without a non-CHG comparison arm were excluded. Outcomes of this study were HABSIs, patient-centered outcomes, such as patient comfort during the bath, and implementation fidelity assessed through five elements: adherence, exposure or dose, quality of the delivery, participant responsiveness, and program differentiation. Three authors independently extracted data and assessed study quality; a random-effects model was used.ResultsWe included 26 studies with 861,546 patient-days and 5259 HABSIs. CHG bathing markedly reduced the risk of HABSIs (IRR = 0.59, 95% confidence interval [CI]: 0.52-0.68). The effect of CHG bathing was consistent within subgroups: randomized (0.67, 95% CI: 0.53-0.85) vs. non-randomized studies (0.54, 95% CI: 0.44-0.65), bundled (0.66, 95% CI: 0.62-0.70) vs. non-bundled interventions (0.51, 95% CI: 0.39-0.68), CHG impregnated wipes (0.63, 95% CI: 0.55-0.73) vs. CHG solution (0.41, 95% CI: 0.26-0.64), and intensive care unit (ICU) (0.58, 95% CI: 0.49-0.68) vs. non-ICU settings (0.56, 95% CI: 0.38-0.83). Only three studies reported all five measures of fidelity, and ten studies did not report any patient-centered outcomes.ConclusionsPatient bathing with CHG significantly reduced the incidence of HABSIs in both ICU and non-ICU settings. Many studies did not report fidelity to the intervention or patient-centered outcomes. For sustainability and replicability essential for effective implementation, fidelity assessment that goes beyond whether a patient received an intervention or not should be standard practice particularly for complex behavioral interventions such as CHG bathing.Trial registrationStudy registration with PROSPERO CRD42015032523 .

Project description:Chlorhexidine gluconate (CHG)-containing dressings are recommended to prevent central line associated bloodstream infections (CLABSIs) and other catheter-related infections. This study compared the effect of 2 CHG dressings on CLABSI, cost of care, and contact dermatitis. A retrospective analysis was conducted using the Premier Healthcare Database of hospitalized patients (n = 53 149) with central venous catheters (CVCs) and receiving either a transparent CHG gel dressing (n = 14 488) or an opaque CHG sponge dressing (n = 38 661) between January 2019 and September 2020. Two cohorts (n = 14 488 each), CHG-Gel and CHG-Sponge, were matched 1:1 using a propensity score method on 33 patient and facility characteristics. CLABSI and contact dermatitis rates, hospital length of stay (LOS), and hospitalization costs were compared using mixed-effect multiple regression. This approach effectively controlled for random clustering effects across hospitals and patients' Diagnosis-Related Group (DRG) classifications. CHG gel dressings were associated with a 41% decrease in CLABSI rates (P = .0008) compared to CHG sponge dressings (0.35%vs 0.60%). A 0.4-day shorter LOS (9.53vs 9.90 days, P = .0001) and a cost saving of $3576 per hospital stay ($40 197 vs $43 774, P = .0179) was observed with CHG gel dressing use. There was no statistically significant difference in contact dermatitis rates (P = .7854) between the CHG-Gel and CHG-Sponge cohorts. The findings of this study suggest that the use of CHG gel dressings may be more effective in reducing the risk of CLABSIs and associated clinical costs compared to CHG sponge dressings in hospitalized patients. Moreover, there appears to be no significant discrepancy in contact dermatitis rates between CHG gel and CHG sponge dressings. Healthcare providers may consider using CHG gel dressings as a standard practice for patients with CVCs to reduce the risk of infections and improve patient outcomes.
