A multicenter quasi-experimental study: impact of a central line infection control program using auditing and performance feedback in five Belgian intensive care units

The use of procedural kits may reduce unscheduled central line dressing changes: A matched pre-post intervention study

Background

Unscheduled dressing changes for central venous lines (CVLs) have been shown to increase the risk of bloodstream infections.

Objective

The objective of this study is to determine if the use of an innovative dressing change kit reduces the rate of unscheduled dressing changes.

Methods

This pre-post interventional study took place at a large, academic, tertiary care center in metro Detroit, Michigan, the United States. We assessed the impact of the interventional dressing change procedure kit on the rate of unscheduled dressing changes for adult patients who underwent placement of a CVL inclusive of a central catheter, peripherally inserted central catheter, or hemodialysis catheter. Data was collected for the pre-intervention cohort through electronic health records (EHRs), while data for the post-intervention cohort were collected by direct observation by trained research staff in combination with EHR data. The primary outcome was the rate of unscheduled dressing changes. Secondary outcomes included rate of unscheduled dressing changes based on admission floor type, etiology of unscheduled dressing changes, and central line-associated bloodstream infections (CLABSIs).

Results

The study included a convenience sample of 1548 CVLs placed between May 2018 and June 2022 with a matched analysis including 488 catheters in each of the pre- and post-intervention groups. The results showed that the unadjusted rate of unscheduled dressing evaluations was significantly reduced from the pre-intervention group (0.21 per day) to the post-intervention group (0.13 per day) (p < .001). The adjusted rate ratio demonstrated the same trend at 1.00 pre- and 0.60 post-intervention (p < .001). Stratifying the analysis based on the highest level of care showed that the intervention was effective in reducing the unadjusted rate of unscheduled dressing evaluations for both the advanced and regular medical floor subgroups pre- to post-intervention; the advanced subgroup had an reduction from 0.22 to 0.15 per day (p = .001), while the regular medical floor subgroup had a reduction from 0.21 to 0.09 per day (p < .001). CLABSIs were similar in both groups (0.6% vs 0.8%; p = 1.00) in pre- and post-intervention groups, respectively.

Discussion

Procedural kits for central line dressing changes are effective in reducing unscheduled dressing changes and may have a role in reducing CLABSI. Further studies assessing the impact of dressing change kits on cost, procedural compliance, and the precise impact on CLABSI are needed.

Knowledge and behavior of professionals about bundled strategies of central venous catheter

OBJECTIVE

To investigate the factors that influence the knowledge and behavior of professionals of neonatal and pediatric units about bundled strategies of insertion of central venous catheter.

METHOD

This is a cross-sectional study, conducted in one neonatal and one pediatric intensive care units in a public hospital in Belo Horizonte, Brazil, from April to July, 2016. The sample consisted of 255 professionals who answered a structured instrument. Descriptive and comparative analyses were made using the SPSS software.

RESULTS

The category nursing professional (p = 0.010), working hours of 12×36 scale (p < 0.001), training as a form of acquiring knowledge (p < 0.001) and participation in training programs (p < 0.001) are associated to greater knowledge about the bundle. Regarding behavior, no significant associations were observed.

CONCLUSION

The study showed that there are factors that influence the knowledge about bundled strategies of insertion of central venous catheter, reflecting the need to consider these practices for making more effective educational practices in health care.

Using the agile implementation model to reduce central line-associated bloodstream infections

BACKGROUND

Central line-associated bloodstream infections (CLABSIs) are among the most common hospital-acquired infections and can lead to increased patient morbidity and mortality rates. Implementation of practice guidelines and recommended prevention bundles has historically been suboptimal, suggesting that improvements in implementation methods could further reductions in CLABSI rates. In this article, we describe the agile implementation methodology and present details of how it was successfully used to reduce CLABSI.

METHODS

We conducted an observational study of patients with central line catheters at 2 adult tertiary care hospitals in Indianapolis from January 2015 to June 2017.

RESULTS

The intervention successfully reduced the CLABSI rate from 1.76 infections per 1,000 central line days to 1.24 (rate ratio = 0.70; P = .011). We also observed reductions in the rates of Clostridium difficile and surgical site infections, whereas catheter-associated urinary tract infections remained stable.

CONCLUSIONS

Using the AI model, we were able to successfully implement evidence-based practices to reduce the rate of CLABSIs at our facility.

IMPACTO DA IMPLEMENTAÇÃO DOS BUNDLES NA REDUÇÃO DAS INFECÇÕES DA CORRENTE SANGUÍNEA: UMA REVISÃO INTEGRATIVA

RESUMO Objetivo: analisar as produções científicas nacionais e internacionais sobre o impacto dos bundles na prevenção de infecção da corrente sanguínea relacionada ao cateter venoso central em unidade de terapia intensiva adulta. Método: revisão integrativa de artigos publicados no Portal Capes, Biblioteca Virtual em Saúde, PubMed, Science Direct, Cochrane, CINAHL e SCOPUS, entre 2011 e 2016. Resultados: encontraram-se 16 artigos, 100% relacionados à implementação dos bundles para a inserção do cateter venoso central e 50% à manutenção deste dispositivo. O tempo de intervenção foi variado, bem como o número de medidas e o período analisado (inserção/manutenção do cateter). No entanto, a redução da infecção da corrente sanguínea relacionada ao dispositivo foi apontada em todos os estudos entre 26% e 100%. Conclusão: a adoção de bundle evidenciou um impacto positivo na redução da infecção. Todavia, não se observou uma relação direta entre o número de medidas descritas nos estudos ou o maior tempo de implementação e taxas mais altas de redução da infecção.

Review of Strategies to Reduce Central Line-Associated Bloodstream Infection (CLABSI) and Catheter-Associated Urinary Tract Infection (CAUTI) in Adult ICUs

Central line-associated bloodstream infection (CLABSI) and catheter-associated urinary tract infection (CAUTI) are costly and morbid. Despite evidence-based guidelines, Some intensive care units (ICUs) continue to have elevated infection rates. In October 2015, we performed a systematic search of the peer-reviewed literature within the PubMed and Cochrane databases for interventions to reduce CLABSI and/or CAUTI in adult ICUs and synthesized findings using a narrative review process. The interventions were categorized using a conceptual model, with stages applicable to both CAUTI and CLABSI prevention: (stage 0) avoid catheter if possible, (stage 1) ensure aseptic placement, (stage 2) maintain awareness and proper care of catheters in place, and (stage 3) promptly remove unnecessary catheters. We also looked for effective components that the 5 most successful (by reduction in infection rates) studies of each infection shared. Interventions that addressed multiple stages within the conceptual model were common in these successful studies. Assuring compliance with infection prevention efforts via auditing and timely feedback were also common. Hospitalists with patient safety interests may find this review informative for formulating quality improvement interventions to reduce these infections.

Prevention of central venous line associated bloodstream infections in adult intensive care units: A systematic review

BACKGROUND

In adult Intensive Care Units, the complexity of patient treatment requirements make the use of central venous lines essential. Despite the potential benefits central venous lines can have for patients, there is a high risk of bloodstream infection associated with these catheters.

AIM

Identify and critique the best available evidence regarding interventions to prevent central venous line associated bloodstream infections in adult intensive care unit patients other than anti-microbial catheters.

METHODS

A systematic review of studies published from January 2007 to February 2016 was undertaken. A systematic search of seven databases was carried out: MEDLINE; CINAHL Plus; EMBASE; PubMed; Cochrane Library; Scopus and Google Scholar. Studies were critically appraised by three independent reviewers prior to inclusion.

RESULTS

Nineteen studies were included. A range of interventions were found to be used for the prevention or reduction of central venous line associated bloodstream infections. These interventions included dressings, closed infusion systems, aseptic skin preparation, central venous line bundles, quality improvement initiatives, education, an extra staff in the Intensive Care Unit and the participation in the 'On the CUSP: Stop Blood Stream Infections' national programme.

CONCLUSIONS

Central venous line associated bloodstream infections can be reduced by a range of interventions including closed infusion systems, aseptic technique during insertion and management of the central venous line, early removal of central venous lines and appropriate site selection.

Effect of intensive education and training of nurses on ventilator-associated pneumonia and central line-associated bloodstream infection incidence in intensive care unit at a tertiary care center in North India

Objective:

The aim was to analyze the impact of education and training of nurses on the incidence of ventilator-associated pneumonia (VAP) and central line-associated bloodstream infection (CLABSI).

Patients and Methods:

A prospective observational study at a tertiary care hospital included adult patients with Intensive Care Unit stay >48 h. The study was done in three phases: in Phase 1, baseline VAP and CLABSI incidence was calculated; in Phase 2, education and training of nurses; and in Phase 3, data were recollected for the incidence of VAP and CLABSI.

Results:

The baseline incidence of VAP in Phase 1 was 28.86/1000 ventilator days and that of CLABSI was 7.89/1000 central-line days. In Phase 3, the incidence of VAP increased to 35.06 and that of CLABSI decreased significantly, 1.73.

Conclusion:

Intensive education and training sessions with feedback from nurses over a period of 6 months led to significant reduction in the incidence of CLABSI; however, the incidence of VAP increased.

Poor adherence to guidelines for preventing central line-associated bloodstream infections (CLABSI): results of a worldwide survey

Background

Central line-associated bloodstream infections (CLABSI) are a cause of increased morbidity and mortality, and are largely preventable. We documented attitudes and practices in intensive care units (ICUs) in 2015 in order to assess compliance with CLABSI prevention guidelines.

Methods

Between June and October 2015, an online questionnaire was made available to medical doctors and nurses working in ICUs worldwide. We investigated practices related to central line (CL) insertion, maintenance and measurement of CLABSI-related data following the SHEA guidelines as a standard. We computed weighted estimates for high, middle and low-income countries using country population as a weight. Only countries providing at least 10 complete responses were included in these estimates.

Results

Ninety five countries provided 3407 individual responses; no low income, 14 middle income (MIC) and 27 high income (HIC) countries provided 10 or more responses. Of the total respondents, 80% (MIC, SE = 1.5) and 81% (HIC, SE = 1.0) reported availability of written clinical guidelines for CLABSI prevention in their ICU; 23% (MIC,SE = 1.7) and 62% (HIC,SE = 1.4) reported compliance to the following (combined) recommendations for CL insertion: hand hygiene, full barrier precaution, chlorhexidine >0.5%, no topic or systemic antimicrobial prophylaxis; 60% (MIC,SE = 2.0) and 73% (HIC,SE = 1.2) reported daily assessment for the need of a central line. Most considered CLABSI measurement key to quality improvement, however few were able to report their CLABSI rate. Heterogeneity between countries was high and country specific results are made available.

Conclusions

This study has identified areas for improvement in CLABSI prevention practices linked to CL insertion and maintenance. Priorities for intervention differ between countries.

Belgian hand hygiene campaigns in ICU, 2005-2015

BACKGROUND

Healthcare-associated infections (HCAI) are still a major problem especially in most intensive care units (ICU). Incompliance by clinical staff with hand hygiene (HH) increases rates of preventable infections. We report the outcome of the Belgian national hand hygiene campaign from 2005 to 2015 with focus on intensive care units.

METHODS

Using the World Health organisation (WHO) standardised observation roster, trained infection control teams measured adherence to HH guidelines by direct observation. HH opportunities were counted and the actual episodes of HH were scored as no HH, HH with water and soap, or HH with alcohol-based hand rub. Measurements were repeatedly done before and after a one month awareness campaign every second year. Compliance was stratified by indication and by type of healthcare worker, and computed as a percentage of the number of HH episodes with water and soap or with alcohol-based hand rub, divided by the number of opportunities.

RESULTS

A total of 108,050 hand hygiene opportunities were observed in ICU during this period. HH compliance increased significantly from 49.6 % before campaign in 2005 to 72.0 % before campaign in 2015. Over the same time frame, post campaign compliance increased from 67.0 to 80.2 %. The number of opportunities observed substantially increased when automated feedback was installed.

CONCLUSIONS

In Belgian intensive care units, hand hygiene compliance is getting improved overtime, though consecutive campaigns with immediate feedback are required to achieve and sustain a high compliance rate.

Evidence-based measures to prevent central line-associated bloodstream infections: a systematic review

Objective:

to identify evidence-based care to prevent CLABSI among adult patients hospitalized in ICUs.

Method:

systematic review conducted in the following databases: PubMed, Scopus, Cinahl, Web of Science, Lilacs, Bdenf and Cochrane Studies addressing care and maintenance of central venous catheters, published from January 2011 to July 2014 were searched. The 34 studies identified were organized in an instrument and assessed by using the classification provided by the Joanna Briggs Institute.

Results:

the studies presented care bundles including elements such as hand hygiene and maximal barrier precautions; multidimensional programs and strategies such as impregnated catheters and bandages and the involvement of facilities in and commitment of staff to preventing infections.

Conclusions:

care bundles coupled with education and the commitment of both staff and institutions is a strategy that can contribute to decreased rates of central line-associated bloodstream infections among adult patients hospitalized in intensive care units.

Active surveillance and safety organizational goals to reduce central line-associated bloodstream infections outside the intensive care unit: 9 years of experience

We performed a quasi-experimental, cohort study in the medical-surgical inpatient wards comparing central line-associated bloodstream infection (CLABSI) rates and microbiologic characteristics in 3 phases. The CLABSI rates decreased 60% from phase 1 to 2 and 61.5% from phase 2 to 3. Gram-positive organisms were most frequently isolated in phases 1 and 3, and gram-negative bacilli were most frequently isolated in phase 2. The CLABSI surveillance and prevention program focusing on patient safety had a significant impact on CLABSI rates.
