Interventions to reduce unnecessary central venous catheter use to prevent central-line–associated bloodstream infections in adults: A systematic review

Effectiveness of de-implementation of low-value healthcare practices: an overview of systematic reviews

BACKGROUND

Reducing low-value care (LVC) is crucial to improve the quality of patient care while increasing the efficient use of scarce healthcare resources. Recently, strategies to de-implement LVC have been mapped against the Expert Recommendation for Implementing Change (ERIC) compilation of strategies. However, such strategies' effectiveness across different healthcare practices has not been addressed. This overview of systematic reviews aimed to investigate the effectiveness of de-implementation initiatives and specific ERIC strategy clusters.

METHODS

We searched MEDLINE (Ovid), Epistemonikos.org and Scopus (Elsevier) from 1 January 2010 to 17 April 2023 and used additional search strategies to identify relevant systematic reviews (SRs). Two reviewers independently screened abstracts and full texts against a priori-defined criteria, assessed the SR quality and extracted pre-specified data. We created harvest plots to display the results.

RESULTS

Of 46 included SRs, 27 focused on drug treatments, such as antibiotics or opioids, twelve on laboratory tests or diagnostic imaging and seven on other healthcare practices. In categorising de-implementation strategies, SR authors applied different techniques: creating self-developed strategies (n = 12), focussing on specific de-implementation strategies (n = 14) and using published taxonomies (n = 12). Overall, 15 SRs provided evidence for the effectiveness of de-implementation interventions to reduce antibiotic and opioid utilisation. Reduced utilisation, albeit inconsistently significant, was documented in the use of antipsychotics and benzodiazepines, as well as in laboratory tests and diagnostic imaging. Strategies within the adapt and tailor to context, develop stakeholder interrelationships, and change infrastructure and workflow ERIC clusters led to a consistent reduction in LVC practices.

CONCLUSION

De-implementation initiatives were effective in reducing medication usage, and inconsistent significant reductions were observed for LVC laboratory tests and imaging. Notably, de-implementation clusters such as change infrastructure and workflow and develop stakeholder interrelationships emerged as the most encouraging avenues. Additionally, we provided suggestions to enhance SR quality, emphasising adherence to guidelines for synthesising complex interventions, prioritising appropriateness of care outcomes, documenting the development process of de-implementation initiatives and ensuring consistent reporting of applied de-implementation strategies.

Use of central venous access devices outside of the pediatric intensive care units

BACKGROUND

Central venous access devices (CVAD) are associated with central line associated bloodstream infection (CLABSI) and venous thromboembolism (VTE). We identified trends in non-intensive care unit (ICU) CVAD utilization, described complication rates, and compared resources between low and high CVAD sites.

METHODS

We combined data from the Pediatric Health Information System (PHIS) database and surveys from included hospitals. We analyzed 10-year trends in CVAD encounters for non-ICU children between 01/2012-12/2021 and described variation and complication rates between 01/2017-12/2021. Using Fisher's exact test, we compared resources between low and high CVAD users.

RESULTS

CVAD use decreased from 6.3% to 3.8% of hospitalizations over 10 years. From 2017-2021, 67,830 encounters with CVAD were identified. Median age was 7 (IQR 2-13) years; 46% were female. Significant variation in CVAD utilization exists (range 1.4-16.9%). Rates of CLABSI and VTE were 4.0% and 3.4%, respectively. Survey responses from 33/41 (80%) hospitals showed 91% had vascular access teams, 30% used vascular access selection guides, and 70% used midline/long peripheral catheters. Low CVAD users were more likely to have a team guiding device selection (100% vs 43%, p = 0.026).

CONCLUSIONS

CVAD utilization decreased over time. Significant variation in CVAD use remains and may be associated with hospital resources.

IMPACT

Central venous access device (CVAD) use outside of the ICU is trending down; however, significant variation exists between institutions. Children with CVADs hospitalized on the acute care units had a CLABSI rate of 4% and VTE rate of 3.4%. 91% of surveyed institutions have a vascular access team; however, the services provided vary between institutions. Even though 70% of the surveyed institutions have the ability to place midline/long peripheral catheters, the majority use these catheters less than a few times per month. Institutions with low CVAD use are more likely to have a vascular access team that guides device selection.

Impact of a Rounding Checklist Implementation in the Trauma Intensive Care Unit on Clinical Outcomes

We aimed to evaluate the effectiveness of an intensive care unit (ICU) round checklist, FAST HUGS BID (Feeding, Analgesia, Sedation, Thromboembolic prophylaxis, Head-of-bed elevation, Ulcer prophylaxis, Glycemic control, Spontaneous breathing trial, Bowel regimen, Indwelling catheter removal, and De-escalation of antibiotics-abbreviated as FD hereafter), in improving clinical outcomes in patients with severe trauma. We included patients admitted to our trauma ICU from 2016 to 2020 and divided them into two groups: before (before-FD, 2016-2017) and after (after-FD, 2019-2020) implementation of the checklist. We compared patient characteristics and clinical outcomes, including ICU and hospital length of stay (LOS) and in-hospital mortality. Survival analysis was performed using Kaplan-Meier curves and multivariable logistic regression models; furthermore, multiple linear regression analysis was used to identify independent factors associated with ICU and hospital LOS. Compared with the before-FD group, the after-FD group had significantly lower in-hospital mortality and complication rates, shorter ICU and hospital LOS, and reduced duration of mechanical ventilation. Moreover, implementation of the checklist was a significant independent factor in reducing ICU and hospital LOS and in-hospital mortality. Implementation of the FD checklist is associated with decreased ICU and hospital LOS and in-hospital mortality.

Current Updates in Rectal Infusion of Fluids and Medications

Purpose of Review

Rectal infusion is a feasible alternative for the immediate administration of medication and fluids when intravenous access is delayed, contraindicated, or unnecessary. Advances in medical device technology have made rectal infusion more practical and easier for medical care providers, and more comfortable for patients. This paper briefly reviews the history of therapeutic rectal infusion, including recent improvements in technology and the existing evidence for the use of this technique.

Recent Findings

While ultrasound-guided peripheral intravenous (PIV) access techniques and other alternatives to landmark-based PIV catheter insertion have recently improved the ability of providers to overcome challenges related to difficult vascular access (DVA), these challenges are increasingly affecting patient outcomes, emergency department throughput, and the cost of medical care. In recent years, waves of parenteral drug, fluid, and supply shortages have affected hospitals. Concurrently, advances in rectal infusion technology have made rectal infusion easier, more comfortable, and more cost-effective than many parenteral options.

Summary

The infusion of resuscitative fluids and medications via the rectal route has previously fallen out of favor due to concurrent improvements in IV access devices. However, this technique demonstrates the potential for a reemergence considering the current challenges facing healthcare providers and systems. Improvements in rectal infusion devices, coupled with an aging population, increased incidence of DVA, shortages in parenteral drugs, fluids, supplies and skilled staff, and the need for care improvements in the post-acute setting have contributed to a greater need for easy, safe and effective alternatives to IV infusion.

Chlorhexidine (di)gluconate locking device for central line infection prevention in intensive care unit patients: a multi-unit, pilot randomized controlled trial

PURPOSE

Intensive care unit (ICU) patients are at risk for central line-associated bloodstream infection (CLABSI) with significant attributable mortality and increased hospital length of stay, readmissions, and costs. Chlorhexidine (di)gluconate (CHG) is used as a disinfectant for central line insertion; however, the feasibility and efficacy of using CHG as a locking solution is unknown.

METHODS

Patients with a central venous access device (CVAD) in situ were randomized to standard care or a CHG lock solution (CHGLS) within 72 hours of ICU admission. The CHG solution was instilled in the lumen of venous catheters not actively infusing. CVAD blood cultures were taken at baseline and every 48 hours. The primary outcome was feasibility including recruitment rate, consent rate, protocol adherence, and staff uptake. Secondary outcomes included CVAD colonization, bacteraemia, and clinical endpoints.

RESULTS

Of 3,848 patients screened, 122 were eligible for the study and consent was obtained from 82.0% of the patients or substitute decision makers approached. Fifty participants were allocated to each group. Tracking logs indicated that the CHGLS was used per protocol 408 times. Most nurses felt comfortable using the CHGLS. The proportion of central line colonization was significantly higher in the standard care group with 40 (29%) versus 26 (18.7%) in the CHGLS group (P=0.009).

CONCLUSIONS

Using a device that delivers CHG into CVADs was feasible in the ICU. Findings from this trial will inform a full-scale randomized controlled trial and provide preliminary data on the effectiveness of CHGLS.

I-DECIDED®-a decision tool for assessment and management of invasive devices in the hospital setting

Indwelling medical devices, including vascular access and urinary catheters, pose a risk for infection, and therefore daily assessment and consideration of their continued need is a patient safety priority. The I-DECIDED® device assessment and decision tool is an evidence-based checklist, designed to improve the assessment, care and timely removal of invasive devices in acute hospitalized patients. This paper explains each step of the tool, with rationale for inclusion.

A Multidisciplinary Approach and Development of an Algorithm for Timely Repair of Central Venous Access in Pediatric Patients

Background: Central venous catheters (CVCs) carry a risk for many complications. This can lead to numerous and prolonged hospitalizations for patients undergoing intravenous nutrition. The aim was to create a standardized protocol for the medical facility to expedite the repair process as well as implement a broadened educational effort for the care of CVCs.

Method: A retrospective chart review was completed for 365 catheter days before implementation. Two protocols were then created in collaboration with the multidisciplinary team. Prospective chart data were subsequently collected 365 catheter days post-implementation.

Result: Pre-implementation (32 encounters), 100% of compromised CVCs required admission. Post-implementation (21 encounters), only 48% of compromised CVCs required admission accompanied by an overall reduction in the number of compromised catheters that presented to the hospital. The average hospital length of stay pre-protocol initiation decreased from 7.2 to 1.8 days post-protocol initiation. The implementation of our algorithm also lead to a decrease in the average cost of compromised CVC repair inpatient ($2741) vs repair in the emergency department ($34,436).

Conclusion: This study demonstrates that working with a multidisciplinary team utilizing a standardized protocol improved the quality of patient care by decreasing hospital admissions for compromised CVCs. The authors also conclude that the expedited repair of CVCs can help alleviate health care costs for both families and the hospital system.

Association of CLABSI With Hospital Length of Stay, Readmission Rates, and Mortality: A Retrospective Review

BACKGROUND

An evidence-based practice (EBP) approach to implementing change is relevant and pertinent to the strategy to improve outcomes for hospitalized patients with central venous catheters (CVC). As health systems endeavor to achieve the ambitious goals of improving the patient experience of care, improving the health of populations, and reducing the cost of health care, it is imperative to understand the impact of a central line-associated bloodstream infection (CLABSI) on outcomes.

AIMS

The purpose of the study was to contribute to the evidence of the association of CLABSI with the outcomes of hospital length of stay (LOS), readmission rates, and mortality rates for hospitalized patients.

METHODS

A retrospective study was conducted, including all hospitalized patients with a CVC within four hospitals in an integrated health system in northwest Ohio and southeast Michigan. The sample population was stratified into two groups, CLABSI and no CLABSI, and the outcomes of interest for each group were compared.

RESULTS

The findings substantiate the association between CLABSI and the hospital mortality rate, LOS, and readmission. Patients with a CVC who develop a CLABSI were 36.6% more likely to die in the hospital and 37.0% more likely to be readmitted compared with patients with a CVC who did not develop a CLABSI. In addition, hospital LOS increased an average of 2 days compared with patients without CLABSI. This study evokes implications for EBP change to reduce the rate of CLABSI and for quality improvement during in-hospital care.

LINKING EVIDENCE TO ACTION

There is an association between CLABSI and hospital mortality rate, LOS, and 30-day readmission outcomes, presenting a profound sense of urgency for EBP change. There were potential variances in processes or practice relative to insertion, maintenance, and removal in the hospitals studied, representing an opportunity to examine the best practices in the hospitals that are performing well. Implementation of EBP requires selecting effective and innovative strategies, with a focus on stakeholder involvement and needs.

Prevention of Central-Line Associated Bloodstream Infections: 2021 Update

Despite a large volume of research in prevention, central line-associated bloodstream infections and catheter-related bloodstream infections continue to cause significant morbidity, mortality, and increased health care costs. Strategies in prevention, including decision about catheter placement, insertion bundles, adherence to standard of care guidelines, and technologic innovations, shown to decrease rates of catheter-related bloodstream infections and central line-associated bloodstream infections are described in this update. The coronavirus disease 2019 pandemic has resulted in increased health care-acquired infections, including central line-associated bloodstream infections.

Reducing Central Line Associated Bloodstream Infections (CLABSIs) by Reducing Central Line Days

Purpose of Review

While reducing unnecessary days present of central venous catheters (CVCs) is part of central line associated bloodstream infection (CLABSI) best practices, there is limited information regarding compliance with this recommendation as well as addressing barriers to compliance.

Recent Findings

Significant work has been directed towards daily audits of necessity and improving communication between members of the medical team. Other critical interventions include utilization of the electronic health record (EHR), leadership support of CLABSI reduction goals, and avoiding CVC placement over more appropriate vascular access.

Summary

Institutions have varied approaches to addressing the issue of removing idle CVCs, and more standardized approaches in checklists as well as communication, particularly on multidisciplinary rounds, will be key to CVC removal. Utilization of the EHR for reminders or appropriate documentation of necessity is a factor. Avoidance of placing a CVC or appropriateness of the CVC is also important to consider.

Trends in central-line-associated bloodstream infections and catheter-associated urinary tract infections in a large acute-care hospital system in New York City, 2016-2019

BACKGROUND

Central-line bloodstream infections (CLABSIs) and catheter-associated urinary tract infections (CAUTIs) negatively impact clinical outcomes and hospital reimbursement. In this report, 4 year trends involving 11 hospitals in New York City were examined.

METHODS

Data from the National Healthcare Safety Network (NHSN) were extracted for 11 acute-care hospitals belonging to the NYC Health + Hospital system from 2016 through 2019. Trends in device infections per 1,000 patient days, device utilization ratios, and standardized infection ratios (SIRs) were examined for the 11 hospitals and for the entire system.

RESULTS

Over the 4-year period, there were progressive declines in central-line days, infections per 1,000 central-line days, and device utilization ratios for the system. The average annual SIRs for the system also declined: 1.40 in 2016, 1.09 in 2017, 1.04 in 2018, and 0.82 in 2019. Case-mix indices correlated with SIRs for CLABSIs. Level 1 trauma centers had higher SIRs and a disproportionately greater number of CLABSIs in patients located in NHSN-defined surgical intensive care units. Similar trends with CAUTIs were noted, with progressive declines in catheter days, infections per 1,000 patient days, device utilization ratios, and SIRs (1.42 in 2016, 0.93 in 2017, 1.18 in 2018, and 0.78 in 2019) over the 4-year period.

CONCLUSIONS

Across an 11-hospital system, continuing efforts to reduce device utilization and infection rates resulted in declining SIRs for CLABSIs and CAUTIs. Hospitals with higher case-mix indices, and particularly level 1 trauma centers, had significantly higher central-line infection rates and SIRs.

Trends in Central Venous Catheter Insertions by Anesthesia Providers: An Analysis of the Medicare Physician Supplier Procedure Summary From 2007 to 2016

BACKGROUND

Central line insertion is a core skill for anesthesiologists. Although recent technical advances have increased the safety of central line insertion and reduced the risk of central line-associated infection, noninvasive hemodynamic monitoring and improved intravenous access techniques have also reduced the need for perioperative central venous access. We hypothesized that the number of central lines inserted by anesthesiologists has decreased over the past decade. To test our hypothesis, we reviewed the Medicare Physician Supplier Procedure Summary (PSPS) database from 2007 to 2016.

METHODS

Claims for central venous catheter placement were identified in the Medicare PSPS database for nontunneled and tunneled central lines. Pulmonary artery catheter insertion was included as a nontunneled line claim. We stratified line insertion claims by specialty for Anesthesiology (including Certified Registered Nurse Anesthetists and Anesthesiology Assistants), Surgery, Radiology, Pulmonary/Critical Care, Emergency Physicians, Internal Medicine, and practitioners who were not anesthesia providers such as Advanced Practice Nurses (APNs) and Physician Assistants (PAs). Utilization rates per 10,000 Medicare beneficiaries were then calculated by specialty and year. Time-based trends were analyzed using Joinpoint linear regression, and the Average Annual Percent Change (AAPC) was calculated.

RESULTS

Between 2007 and 2016, total claims for central venous catheter insertions of all types decreased from 440.9 to 325.3 claims/10,000 beneficiaries (AAPC = -3.4, 95% confidence interval [CI], -3.6 to -3.2: P < .001). When analyzed by provider specialty and year, the number of nontunneled line insertion claims fell from 43.1 to 15.9 claims/10,000 (AAPC = -7.1; -7.3 to -7.0: P < .001) for surgeons, from 21.3 to 18.5 claims/10,000 (AAPC = -2.5; -2.8 to -2.1: P < .001) for radiologists, and from 117.4 to 72.7 claims/10,000 (AAPC = -5.2; 95% CI, -6.3 to -4.0: P < .001) for anesthesia providers. In contrast, line insertions increased from 18.2 to 26.0 claims/10,000 (AAPC = 3.2; 2.3-4.2: P < .001) for Emergency Physicians and from 3.2 to 9.3 claims/10,000 (AAPC = 6.0; 5.1-6.9: P < .001) for PAs and APNs who were not anesthesia providers. Among anesthesia providers, the share of line claims made by nurse anesthetists increased by 14.5% over the time period.

CONCLUSIONS

We observed a 38.3% decrease in claims for nontunneled central lines placed by anesthesiologists from 2007 to 2016. These findings have implications for anesthesiology resident training and maintenance of competence among practicing clinicians. Further research is needed to clarify the effect of decreasing line insertion numbers on line insertion competence among anesthesiologists.

Preventing catheter-related infections in cancer patients: a review of current strategies

Introduction: Central line-associated bloodstream infections (CLABSI) are a frequent cause of healthcare-associated infections, increasing healthcare costs and decreasing the quality of life for critically and chronically ill patients such as those with cancer. These infections are largely preventable and have been significantly reduced throughout the United States. However, further reduction of CLABSI requires continued innovation in preventive strategies.Areas covered: We provide an overview of the recent medical literature on catheter-related infections among cancer patients, discussing epidemiology, risk factors, and pathogenesis of CLABSI with a focus on the newest and current preventive measures. The data discussed here were retrieved mainly from clinical trials, meta-analyses, and systematic reviews published in the English language using a MEDLINE database search from 1 January 1990 until the end of December 2019.Expert opinion: The growing impact of CLABSI on the healthcare setting and mortality and morbidity rates in cancer patients calls for novel technologies for preventing central line-related infections. Advances in antimicrobial lock therapy are not limited to salvage therapy but have also provided a novel and promising prophylactic approach to CLABSI. Also, the use of antimicrobial-coated catheters with chlorhexidine-impregnated dressings, along with the application of insertion and maintenance bundles, is an effective and cost-effective approach for preventing central line-related infections.
