Reduction of catheter-associated urinary tract infections among patients in a neurological intensive care unit: a single institution's success

Pragmatic review of interventions to prevent catheter-associated urinary tract infections (CAUTIs) in adult inpatients

BACKGROUND

Urinary tract infections (UTIs) are one of the most common hospital-acquired complications. Insertion of a urinary catheter and the duration of catheterization are the main risk factors, with catheter-associated UTIs (CAUTIs) accounting for 70-80% of hospital-acquired UTIs. Guidance is available regarding the prevention of hospital-acquired CAUTIs; however, how best to operationalize this guidance remains a challenge.

AIM

To map and summarize the peer-reviewed literature on model-of-care interventions for the prevention of CAUTIs in adult inpatients.

METHODS

PubMed, CINAHL and SCOPUS were searched for articles that reported UTI, CAUTI or urinary catheter outcomes. Articles were screened systematically, data were extracted systematically, and interventions were classified by intervention type.

FINDINGS

This review included 70 articles. Interventions were classified as single component (N=19) or multi-component (N=51). Single component interventions included: daily rounds or activities (N=4), protocols and procedure changes (N=6), reminders and order sets (N=5), audit and feedback interventions (N=3), and education with simulation (N=1). Overall, daily catheter reviews and protocol and procedure changes demonstrated the most consistent effects on catheter and CAUTI outcomes. The components of multi-component interventions were categorized to map common elements and identify novel ideas.

CONCLUSION

A range of potential intervention options with evidence of a positive effect on catheter and CAUTI outcomes was identified. This is intended to provide a 'menu' of intervention options for local decision makers, enabling them to identify interventions that are relevant and feasible in their local setting.

Development and validation of a user-friendly risk nomogram for the prediction of catheter-associated urinary tract infection in neuro-intensive care patients

OBJECTIVE

This study aimed to develop a user-friendly nomogram model to evaluate the risk of catheter-associated urinary tract infections in neuro-critically ill patients.

METHODS

A retrospective cohort analysis was conducted on 537 patients with indwelling catheters admitted to the neuro-intensive care unit. Patients' general information, laboratory examination findings, and clinical characteristics were collected. Multivariate regression analysis was applied to develop the nomogram for the prediction of catheter-associated urinary tract infections in this group of patients. The discriminative capacity, calibration ability, and clinical effectiveness of the nomogram were evaluated.

RESULTS

The occurrence of catheter-associated urinary tract infections was 3.91 % and Escherichia coli was the major causative pathogen. Multivariate regression analysis showed that age ≥ 60 years (odds ratio: 35.2, 95 % confidence interval: 2.3-550.8), epilepsy (39.3, 5.1-301.4), a length of neuro-intensive care stay > 30 days (272.2, 8.3-8963.5), and low albumin levels (<35 g/L) (12.1, 2.1-69.9) were independent risk factors associated with catheter-associated urinary tract infection in neuro-intensive care patients. The nomogram demonstrated good calibration and discrimination in both the training and the validation sets. The model exhibited good clinical use since the decision curve analysis covered a large threshold probability.

CONCLUSIONS

We developed a user-friendly nomogram to predict catheter-associated urinary tract ibfection in neuro-intensive care patients. The nomogram incorporated clinical variables collected on admission (age, admission diagnosis, and albumin levels) and the length of stay and enabled the effective prediction of the likelihood of catheter-associated urinary tract infections.

Reducing CAUTI in patients with acute urinary retention in the critical care setting: A pilot study with electronic medical record analytics

BACKGROUND

This study implemented and evaluated an algorithm protocol for management of indwelling urinary catheters (IUCs) among patients treated for acute urinary retention (AUR) in an intensive care unit. The algorithm protocol (1) instituted in and out catheterization before placing an IUC for retention; (2) encouraged more consistent use of medications for AUR; and (3) provided for prompt removal of IUCs placed for AUR.

METHODS

An uncontrolled pre- and post-test intervention approach was used to assess the impact of the algorithm on the treatment of AUR. Bivariate and multivariate analyses assessed data collected using 2 approaches: (1) electronic extracts from the electronic medical record (EMR) vs (2) manual chart reviews.

RESULTS

Findings suggest that the intervention decreased indwelling IUC days by 1.93 average days and increased medication prescription rates. An EMR extract identified fewer catheters per patient pre-intervention than a manual chart review, but otherwise the differences observed in the EMR extract and manual chart review were insignificant.

CONCLUSIONS

Implications for practitioners and administrators are that the algorithm protocol may reduce CAUTI risk and - provided consistent EMR documentation - EMR extracts may represent an efficient and effective approach for monitoring data when spreading the intervention.

Implementation of systematic safety checklists in a neurocritical care unit: a quality improvement study

BACKGROUND AND OBJECTIVES

Structured and systematised checklists have been shown to prevent complications and improve patient care. We evaluated the implementation of systematic safety checklists in our neurocritical care unit (NCCU) and assessed its effect on patient outcomes.

DESIGN/METHODS

This quality improvement project followed a Plan-Do-Study-Act (PDSA) methodology. A checklist for medication reconciliation, thromboembolic prophylaxis, glycaemic control, daily spontaneous awakening, breathing trial, diet, catheter/lines duration monitoring and antibiotics de-escalation was implemented during daily patient rounds. Main outcomes included the rate of new infections, mortality and NCCU-length of stay (LOS). Intervened patients were compared with historical controls after propensity score and Euclidean distance matching to balance baseline covariates.

RESULTS

After several PDSA iterations, we applied checklists to 411 patients; the overall average age was 61.34 (17.39). The main reason for admission included tumour resection (31.39%), ischaemic stroke (26.76%) and intracerebral haemorrhage (10.95%); the mean Sequential Organ Failure Assessment (SOFA) score was 2.58 (2.68). At the end of the study, the checklist compliance rate throughout the full NCCU stays reached 97.11%. After controlling for SOFA score, age, sex and primary admitting diagnosis, the implementation of systematic checklists significantly correlated with a reduced LOS (ß=-0.15, 95% CI -0.24 to -0.06), reduced rate of any new infections (OR 0.59, 95% CI 0.40 to 0.87) and reduced urinary tract infections (UTIs) (OR 0.23, 95% CI 0.09 to 0.55). Propensity score and Euclidean distance matching yielded 382 and 338 pairs with excellent covariate balance. After matching, outcomes remained significant.

DISCUSSION

The implementation of safety checklists in the NCCU proved feasible, easy to incorporate into the NCCU workflow, and a helpful tool to improve adherence to practice guidelines and quality of care measurements. Furthermore, our intervention resulted in a reduced NCCU-LOS, rate of new infections and rate of UTIs compared with propensity score and Euclidean distance matched historical controls.

Effectiveness and safety of a program for appropriate urinary catheter use in stroke care: A multicenter prospective study

OBJECTIVES

Since patients with stroke frequently develop bladder dysfunction, a careful approach is required to reduce unnecessary indwelling urinary catheter (IUC) for preventing catheter-associated urinary tract infection (CAUTI). This study aimed to assess the effectiveness and safety of a program to promote appropriate IUC use in stroke care.

METHODS

We conducted a prospective interrupted time series study in three tertiary care hospitals in Japan. Adult patients with acute stroke were eligible. The study consisted of three phases: baseline, education and implementation. Our program included an assessment of IUC indications, educational meetings among healthcare professionals, reminders for removal of inappropriate IUC and a urinary retention protocol. The primary outcome was the proportion of inappropriate IUC use to assess effectiveness. The device utilization ratio and incidence of CAUTI were examined to assess effectiveness, and incidences of urinary retention and all symptomatic urinary tract infection (UTI) were examined to assess safety.

RESULTS

Among 976 patients who met the inclusion criteria, 738 were analysed. Inappropriate IUC use decreased from 50.1% in the baseline phase to 22.5% in the implementation phase (absolute risk reduction in interrupted time series analysis 42.4% [95% confidence interval, 19.2%-65.6%]). The device utilization ratio decreased from 0.302 to 0.194 (p < 0.001), whereas CAUTI did not change significantly (from 8.81 to 8.28 per 1000 catheter-days; incidence rate ratio 0.95 [0.44-1.94]). All symptomatic UTI decreased from 9.5% to 4.9% (p = 0.015), with no increase in urinary retention.

CONCLUSIONS

Our program improved the appropriateness of IUC use in stroke care while ensuring safety.

Catheter-Associated Urinary Tract Infection in Neurological Intensive Care Units: A Narrative Review

Catheter-associated urinary tract infection (CAUTI) is among the most common types of healthcare-associated infection (HAI), which is associated with poor outcomes and prolonged hospitalization in critically ill patients. Previous studies have mentioned that patients admitted to neurological ICUs are at higher risk of CAUTI compared to patients in other ICU settings. This review paper aims to review studies published during the last decade that evaluated the incidence, risk factors, causative pathogens, and preventive strategies and treatment in neuro-critically ill patients.

A single institution pre-/post-comparison after introduction of an external urinary collection device for female medical patients

Background

External urinary collection devices (EUCDs) may serve as an alternative to indwelling urinary catheters (IUCs) and decrease the rate of catheter associated urinary tract infections (CAUTIs). PureWick® is a novel female EUCD; however, no study has definitively proven benefit regarding reduction of CAUTIs.

Aim

We sought to compare the CAUTI rate and IUC days before and after availability of the PureWick® EUCD at a single institution. We provide a descriptive analysis of female medical patients receiving an EUCD.

Methods

A retrospective review of adult female patients admitted to a single institution on a medical service who received an IUC and/or an EUCD was performed. Patients who received an IUC in the 3 months before EUCD availability (PRE) were compared to patients who received an IUC and/or EUCD in the 12 months after (POST).

Results

Out of 848 female patients, 292 received an EUCD in the POST cohort and overall, 656 received an IUC (259 (100%) PRE vs. 397 (67.4%) POST). Compared to the PRE cohort, the POST cohort had a higher number of IUC days (median, 3 vs 2 days, p = 0.001) and a higher rate of CAUTI (infections per 1000 catheter days, 9.3 vs 2.3, p = 0.001). The rate of UTI associated with EUCD use was 9.8 infections per 1000 device days.

Discussion

While EUCDs might appear to be a promising alternative to IUCs for female patients, this single center pre-/post-analysis found that both the number of IUC days and the CAUTI rate increased after introduction of a female EUCD.

Intervention to reduce unnecessary urinary catheter use in a large academic health science centre: A one-group, pretest, posttest study with a theory-based process evaluation

AIM

To evaluate an intervention to reduce unnecessary urinary catheter use and prevent catheter-associated urinary-tract infections (CAUTI) in hospitalized patients across an academic health science centre.

METHODS

We conducted a one-group, pretest, posttest study with a theory-based process evaluation. Phase 1 consisted of a pre/postintervention to test the impact of a CAUTI protocol. Audits on four units were conducted, and data were analysed descriptively. Phase 2 consisted of a theory-based process evaluation to understand the barriers/enablers to the implementation. Semistructured interviews were conducted and then analysed using a systematic approach.

RESULTS

In Phase 1, all inpatients with urinary catheters admitted to the units (N = 4) during the study period (N = 99, pre) and (N = 99, post) were included. CAUTI prevalence rate was 18.2% pre versus 14.1% post (p = .563). In Phase 2, participants (N = 18) who worked on the units were interviewed, and a total of 13 barriers and 19 enablers were found.

Catheter-associated urinary tract infection reduction in critical care units: a bundled care model

Catheter-associated urinary tract infections (CAUTIs) represent approximately 9% of all hospital acquired infections, and approximately 65%–70% of CAUTIs are believed to be preventable. In the spring of 2013, Boston Medical Center (BMC) began an initiative to decrease CAUTI rates within its intensive care units (ICUs). A CAUTI taskforce convened and reviewed process maps and gap analyses. Based on Centers for Disease Control and Prevention (CDC) and Institute for Healthcare Improvement (IHI) guidelines, and delineated by the Healthcare Infection Control Practices Advisory Committee 2009 guidelines, all BMC ICUs sequentially implemented plan–do–study–act cycles based on which measures were most easily adaptable and believed to have the highest impact on CAUTI rates. Implementation of five care bundles spanned 5 years and included (1) processes for insertion and maintenance of foley catheters; (2) indications for indwelling foley catheters; (3) appropriate testing for CAUTIs; (4) alternatives to indwelling devices; and (5) sterilisation techniques. Daily rounds by unit nursing supervisors and inclusion of foley catheter necessity on daily ICU checklists held staff accountable on a daily basis. With these interventions, the total number of CAUTIs at BMC decreased from 53 in 2013 to 9 in 2017 (83% reduction) with a 33.8% reduction in indwelling foley catheter utilisation during the same time period. Adapted protocols showed success in decreasing the CAUTI rate and indwelling foley catheter usage in all of the BMC ICU’s. While all interventions had favourable and additive trends towards decreasing the CAUTI rate, the CAUTI awareness education, insertion and removal protocols and implementation of PureWick female incontinence devices had clear and significant effects on decreasing CAUTI rates. Our project provides a framework for improving HAIs using rapid cycle testing and U-chart data monitoring. Targeted education efforts and standardised checklists and protocols adapted sequentially are low-cost and high yield efforts that may decrease CAUTIs in ICU settings.

Catheter-Associated Urinary Tract Infections in the Adult Patient Group: A Qualitative Systematic Review on the Adopted Preventative and Interventional Protocols From the Literature

Catheter-associated urinary tract infections (CA-UTIs) are among the most common nosocomial infections acquired by patients in health care settings. A significant risk factor for CA-UTIs is the duration of catheterization. To summarize the current strategies and interventions in reducing urinary tract infections associated with urinary catheters, use and the need for re-catheterization on the rate of CA-UTIs, we performed a systematic review. A rapid evidence analysis was carried out in the Medline (via Ovid) and the Cochrane Library for the periods of January 2005 till April 2021. The main inclusion criterion required to be included in this review was symptomatic CA-UTI in adults as a primary or secondary outcome in all the included studies. Only randomized trials and systematic reviews were included, reviewed, evaluated, and abstracted data from the 1145 articles that met the inclusion criteria. A total of 1145 articles were identified, of which 59 studies that met the inclusion criteria were selected. Studies of relevance to CA-UTIs were based on: duration of catheterization, indication for catheterization, catheter types, UTI prophylaxis, educational proposals and approaches, and mixed policies and interventions. The duration of catheterization is the contributing risk factor for CA-UTI incidence; longer-term catheterization should only be undertaken where needed indications. The indications for catheterization should be based on individual base to base cases. The evidence for systemic prophylaxis instead of when clinically indicated is still equivocal. However, antibiotic-impregnated catheters reduce the risk of symptomatic CA-UTIs and bacteriuria and are more cost-effective than other impregnated catheter types. Antibiotic resistance, potential side effects and increased healthcare costs are potential disadvantages of implementing antibiotic prophylaxis. Multiple interventions and measures such as reducing the number of catheters in place, removing catheters at their earliest, clinically appropriate time, reducing the number of unnecessary catheters inserted, decrease antibiotic administration unless clinically needed, raising more awareness and provide training of nursing personnel on the latest guidelines, can effectively lower the incidence of CA-UTIs.

A Bundle-Based Approach to Prevent Catheter-Associated Urinary Tract Infections in the Intensive Care Unit

BACKGROUND

Catheter-associated urinary tract infections are the second most common health care-associated infections, occurring most frequently in intensive care units. These infections negatively affect patient outcomes and health care costs.

LOCAL PROBLEM

The targeted institution for this improvement project reported 13 catheter-associated urinary tract infections in 2018, exceeding the hospital's benchmark of 4 or fewer such events annually. Six of the events occurred in the intensive care unit. Project objectives included a 30% reduction in reported catheter-associated urinary tract infections, 20% reduction in urinary catheter days, and 75% compliance rating in catheter-related documentation in the intensive care unit during the intervention phase.

METHODS

This project used a pre-post design over 2 consecutive 4-month periods. The targeted population was critically ill patients aged 18 and older who were admitted to the intensive care unit. A set of bundled interventions was implemented, including staff education, an electronic daily checklist, and a nurse-driven removal protocol for indwelling urinary catheters. Data were analyzed using mixed statistics, including independent samples t tests and Fisher exact tests.

RESULTS

No catheter-associated urinary tract infections were reported during the intervention period, reducing the rate by 1.33 per 1000 catheter days. There was a 10.5% increase in catheter days, which was not statistically significant (P = .12). Documentation compliance increased significantly from 50.0% before to 83.3% during the intervention (P = .01).

CONCLUSIONS

This bundled approach shows promise for reducing catheter-associated urinary tract infections in critical care settings. The concept could be adapted for other health care-associated infections.

Partnership among hospitals to reduce healthcare associated infections: a quasi-experimental study in Brazilian ICUs

BACKGROUND

Healthcare-associated infections (HAIs) are relevant in developing countries where frequencies can be at least 3 times higher than in developed countries. The purpose of this research was to describe the intervention implemented in intensive care units (ICUs) to reduce HAIs through collaborative project and analyze the variation over 18 months in the incidence density (ID) of the three main HAIs: ventilator associated pneumonia (VAP), central line-associated bloodstream infections (CLABSIs) and catheter-related urinary tract infections (CAUTIs) and also the length of stay and mortality in these ICUs.

METHODS

A quasi-experimental study in five public adult clinical-surgical ICUs, to reduce HAIs, through interventions using the BTS-IHI "Improvement Model", during 18 months. In the project, promoted by the Ministry of Health, Brazilian philanthropic hospitals certified for excellence (HE), those mostly private, certified as excellence and exempt from security contributions, regularly trained and monitored public hospitals in diagnostics, data collection and in developing cycles to improve quality and to prevent HAIs (bundles). In the analysis regarding the length of stay, mortality, the IDs of VAP, CLABSIs and CAUTIs over time, a Generalized Estimating Equation (GEE) model was applied for continuous variables, using the constant correlation (exchangeable) between assessments over time. The model estimated the average difference (β coefficient of the model) of the measures analyzed during two periods: a period in the year 2017 (prior to implementing the project) and in the years 2018 and 2019 (during the project).

RESULT

A mean monthly reduction of 0.427 in VAP ID (p = 0.002) with 33.8% decrease at the end of the period and 0.351 in CAUTI ID (p = 0.009) with 45% final decrease. The mean monthly reduction of 0.252 for CLABSIs was not significant (p = 0.068). Length of stay and mortality rates had no significant variation.

CONCLUSIONS

Given the success in reducing VAP and CAUTIs in a few months of interventions, the achievement of the collaborative project is evident. This partnership among public hospitals/HE may be applied to other ICUs including countries with fewer resources.

Protocolized Urine Sampling is Associated with Reduced Catheter-associated Urinary Tract Infections: A Pre- and Postintervention Study

Background

Standard urine sampling and testing techniques do not mitigate against detection of colonization, resulting in false positive catheter-associated urinary tract infections (CAUTI). We aimed to evaluate whether a novel protocol for urine sampling and testing reduces rates of CAUTI.

Methods

A preintervention and postintervention study with a contemporaneous control group was conducted at 2 campuses (test and control) of the same academic medical center. The test campus implemented a protocol requiring urinary catheter removal prior to urine sampling from a new catheter or sterile straight catheterization, along with urine bacteria and pyuria screening prior to culture. Primary outcomes were test campus CAUTI rates, compared between each 9-month pre- and postintervention epoch. Secondary outcomes included the percent reductions in CAUTI rates, compared between the test campus and a propensity score–matched cohort at the control campus.

Results

A total of 7991 patients from the test campus were included in the primary analysis, and 4264 were included in the propensity score–matched secondary analysis. In the primary analysis, the number of CAUTI cases per 1000 patients was reduced by 77% (6.6 to 1.5), the number of CAUTI cases per 1000 catheter days was reduced by 63% (5.9 to 2.2), and the number of urinary catheter days per patient was reduced by 37% (1.1 to 0.69; all P values ≤ .001). In the propensity score–matched analysis, the number of CAUTI cases per 1000 patients was reduced by 82% at the test campus, versus 57% at the control campus; the number of CAUTI cases per 1000 catheter days declined by 68% versus 57%, respectively; and the number of urinary catheter days per patient decreased by 44% versus 1%, respectively (all P values &lt; .001).

Conclusions

Protocolized urine sampling and testing aimed at minimizing contamination by colonization was associated with significantly reduced CAUTI infection rates and urinary catheter days.

Beyond the Brain: The Systemic Pathophysiological Response to Acute Ischemic Stroke

Stroke research has traditionally focused on the cerebral processes following ischemic brain injury, where oxygen and glucose deprivation incite prolonged activation of excitatory neurotransmitter receptors, intracellular calcium accumulation, inflammation, reactive oxygen species proliferation, and ultimately neuronal death. A recent growing body of evidence, however, points to far-reaching pathophysiological consequences of acute ischemic stroke. Shortly after stroke onset, peripheral immunodepression in conjunction with hyperstimulation of autonomic and neuroendocrine pathways and motor pathway impairment result in dysfunction of the respiratory, urinary, cardiovascular, gastrointestinal, musculoskeletal, and endocrine systems. These end organ abnormalities play a major role in the morbidity and mortality of acute ischemic stroke. Using a pathophysiology-based approach, this current review discusses the pathophysiological mechanisms following ischemic brain insult that result in end organ dysfunction. By characterizing stroke as a systemic disease, future research must consider bidirectional interactions between the brain and peripheral organs to inform treatment paradigms and develop effective, comprehensive therapeutics for acute ischemic stroke.

When guidelines conflict: patient safety, quality of life, and CAUTI reduction in patients with spinal cord injury

The current Medicare payment structure and some of the recent guidelines aimed at reducing catheter-associated urinary tract infections may be generating a financial incentive for the protocolized, systematic removal of indwelling catheters in hospitalized patients-including those with spinal cord injury. This creates a tension with the Consortium for Spinal Cord Medicine's clinical practice guidelines for the management of neurogenic bladder. This article presents a series of cases and a discussion of the implications with regard to patient safety and quality of life.

Identifying the risk factors for catheter-associated urinary tract infections: a large cross-sectional study of six hospitals

MOTIVATION

Catheter-associated urinary tract infections (CAUTI) are a common and serious healthcare-associated infection. Despite many efforts to reduce the occurrence of CAUTI, there remains a gap in the literature about CAUTI risk factors, especially pertaining to the effect of catheter dwell-time on CAUTI development and patient comorbidities.

OBJECTIVE

To examine how the risk for CAUTI changes over time. Additionally, to assess whether time from catheter insertion to CAUTI event varied according to risk factors such as age, sex, patient type (surgical vs medical) and comorbidities.

DESIGN

Retrospective cohort study of all patients who were catheterised from 2012 to 2016, including those who did and did not develop CAUTIs. Both paediatric and adult patients were included. Indwelling urinary catheterisation is the exposure variable. The variable is interval, as all participants were exposed but for different lengths of time.

SETTING

Urban academic health system of over 2500 beds. The system encompasses two large academic medical centres, two community hospitals and a paediatric hospital.

RESULTS

The study population was 47 926 patients who had 61 047 catheterisations, of which 861 (1.41%) resulted in a CAUTI. CAUTI rates were found to increase non-linearly for each additional day of catheterisation; CAUTI-free survival was 97.3% (CI: 97.1 to 97.6) at 10 days, 88.2% (CI: 86.9 to 89.5) at 30 days and 71.8% (CI: 66.3 to 77.8) at 60 days. This translated to an instantaneous HR of. 49%-1.65% in the 10-60 day time range. Paraplegia, cerebrovascular disease and female sex were found to statistically increase the chances of a CAUTI.

CONCLUSIONS

Using a very large data set, we demonstrated the incremental risk of CAUTI associated with each additional day of catheterisation, as well as the risk factors that increase the hazard for CAUTI. Special attention should be given to patients carrying these risk factors, for example, females or those with mobility issues.

The preventable proportion of healthcare-associated infections 2005-2016: Systematic review and meta-analysis

OBJECTIVE

The preventable proportion of healthcare-associated infections (HAIs) may decrease over time as standards of care improve. We aimed to assess the proportion of HAIs prevented by multifaceted infection control interventions in different economic settings.

METHODS

In this systematic review and meta-analysis, we searched OVID Medline, EMBASE, CINAHL, PubMed, and The Cochrane Library for studies published between 2005 and 2016 assessing multifaceted interventions to reduce catheter-associated urinary tract infections (CAUTIs), central-line-associated bloodstream infections (CLABSIs), surgical site infections (SSIs), ventilator-associated pneumonia (VAP), and hospital-acquired pneumonia not associated with mechanical ventilation (HAP) in acute-care or long-term care settings. For studies reporting raw rates, we extracted data and calculated the natural log of the risk ratio and variance to obtain pooled risk ratio estimates.

RESULTS

Of the 5,226 articles identified by our search, 144 studies were included in the final analysis. Pooled incidence rate ratios associated with multifaceted interventions were 0.543 (95% confidence interval [CI], 0.445-0.662) for CAUTI, 0.459 (95% CI, 0.381-0.554) for CLABSI, and 0.553 (95% CI, 0.465-0.657) for VAP. The pooled rate ratio was 0.461 (95% CI, 0.389-0.546) for interventions aiming at SSI reduction, and for VAP reduction initiatives, the pooled rate ratios were 0.611 (95% CI, 0.414-0.900) for before-and-after studies and 0.509 (95% CI, 0.277-0.937) for randomized controlled trials. Reductions in infection rates were independent of the economic status of the study country. The risk of bias was high in 143 of 144 studies (99.3%).

CONCLUSIONS

Published evidence suggests a sustained potential for the significant reduction of HAI rates in the range of 35%-55% associated with multifaceted interventions irrespective of a country's income level.

A pre and post intervention study to reduce unnecessary urinary catheter use on general internal medicine wards of a large academic health science center

BACKGROUND

Urinary catheters are a common medical intervention, yet they can also be associated with harmful adverse events such as infection, urinary tract trauma, delirium and patient discomfort. The purpose of this study was to describe the use of the SafetyLEAP program to drive improvement efforts, and specifically to reduce the use of urinary catheters on general internal medicine wards.

METHODS

A pre and post intervention study using the SafetyLEAP program was performed with urinary catheter prevalence as the primary outcome on two general internal medicine wards in a large academic health sciences center.

RESULTS

A total of n = 534 patients (n = 283 from ward #1; and n = 252 from ward #2) were included in the initial audit and feedback portion of the study and 1601 patients (n = 824 pre-intervention and n = 777 post-intervention were included in the planned quality improvement portion of the study). A total of 379 patients during the quality improvement intervention had a urinary catheter. Overall, the adherence to the SafetyLEAP program was 97.4% on both general internal medicine wards. The daily catheter point prevalence decreased from 22 to 13%. After the implementation of the program, the urinary catheter utilization ratio (defined as urinary catheter days/patient days) declined from 0.14 to 0.12. Catheter-associated urinary tract infections (CAUTI) were unchanged.

CONCLUSION

The SafetyLEAP program can help provide a systematic approach to the detection, and reduction of safety incidents. Future studies should aim at refining and implementing this intervention broadly.

A Technology Intervention for Nurses Engaged in Preventing Catheter-Associated Urinary Tract Infections

Catheter-associated urinary tract infections account for 40% of healthcare-acquired infections. This study explored the addition of cloud-based software technology to an established nursing quality improvement program to reduce catheter-associated urinary tract infections. Unit-based nurse champions evaluated peers' evidence-based catheter-associated urinary tract infection prevention practices using manual, paper-based feedback. That process achieved reduced rates of catheter-associated urinary tract infection over 18 months. However, it was resource intensive. Cloud-based software technology was introduced to replace the paper. Nurse champions' satisfaction, catheter-associated urinary tract infection and indwelling urinary catheter utilization, and prevention practices were compared before and after the technology intervention. Compliance with the provision of a chlorhexidine bath demonstrated improvement (P = .003), while other practice measures did not significantly change. The indwelling urinary catheter utilization ratio was lower (P = .01), yet the intervention yielded no change in catheter-associated urinary tract infection rates. The short time interval of the intervention was potentially a contributing factor in no significant rate change. Nurse champions (N = 14) were more satisfied with the cloud-based technology (P = .004), the clarity of improvement targets (P = .004), and the speed of sharing data (P = .001). Their time to share data decreased from 4 days or more to 1 hour or less. Nurse champions readily adopted the cloud-based technology. These findings suggest additional research on technology innovations for nursing quality improvement is needed.

Reducing indwelling urinary catheter use through staged introduction of electronic clinical decision support in a multicenter hospital system

Objective

To integrate electronic clinical decision support tools into clinical practice and to evaluate the impact on indwelling urinary catheter (IUC) use and catheter-associated urinary tract infections (CAUTIs).

Design, Setting, and Participants

This 4-phase observational study included all inpatients at a multicampus, academic medical center between 2011 and 2015.

Interventions

Phase 1 comprised best practices training and standardization of electronic documentation. Phase 2 comprised real-time electronic tracking of IUC duration. In phase 3, a triggered alert reminded clinicians of IUC duration. In phase 4, a new IUC order (1) introduced automated order expiration and (2) required consideration of alternatives and selection of an appropriate indication.

Results

Overall, 2,121 CAUTIs, 179,070 new catheters, 643,055 catheter days, and 2,186 reinsertions occurred in 3·85 million hospitalized patient days during the study period. The CAUTI rate per 10,000 patient days decreased incrementally in each phase from 9·06 in phase 1 to 1·65 in phase 4 (relative risk [RR], 0·182; 95% confidence interval [CI], 0·153–0·216; P<·001). New catheters per 1,000 patient days declined from 53·4 in phase 1 to 39·5 in phase 4 (RR, 0·740; 95% CI, 0·730; P<·001), and catheter days per 1,000 patient days decreased from 194·5 in phase 1 to 140·7 in phase 4 (RR, 0·723; 95% CI, 0·719–0·728; P<·001). The reinsertion rate declined from 3·66% in phase 1 to 3·25% in phase 4 (RR, 0·894; 95% CI, 0·834–0·959; P=·0017).

Conclusions

The phased introduction of decision support tools was associated with progressive declines in new catheters, total catheter days, and CAUTIs. Clinical decision support tools offer a viable and scalable intervention to target hospital-wide IUC use and hold promise for other quality improvement initiatives.

Health Care-Associated Infections after Subarachnoid Hemorrhage

OBJECTIVE

Health care-associated infections (HAIs) after subarachnoid hemorrhage (SAH) are prevalent; however, data describing epidemiology of infection are limited. This study reports incidence rates, risk factors, and the resulting SAH patient-related outcomes.

METHODS

We studied the incidence of HAIs acquired in the intensive care unit (ICU) over a 6-year period. We used Bayesian Model Averaging to identify risk factors associated with an increased risk of HAIs, particularly urinary tract infections (UTI), pneumonia, and ventriculostomy-associated infections (VAI). We also examined the impact of HAIs on risk of vasospasm, ICU and hospital length of stay, and discharge disposition and adjusted for other risk factors.

RESULTS

Of 419 patients with SAH, 66 (15.8%) developed 79 HAI episodes. Mean HAI incidence rates (per 1000 ICU-days) were UTI, 7.1; pneumonia, 4.3; and VAI, 2.4. The admission characteristic associated with increased risk of overall HAI, UTI, and VAI was diabetes mellitus. Hunt and Hess grades III-V were associated with increased risk of overall HAI and VAI. Male gender, intraventricular hemorrhage, and blood glucose level (>10) were associated with increased risk of pneumonia, whereas the incidence was lower in the presence of steroids. HAI was associated with increased length of stay of 10 ICU-days and 22 hospital-days, but not vasospasm or poor discharge disposition.

CONCLUSIONS

HAIs are serious complications after SAH associated with prolonged ICU and hospital length of stay. Additional rigorous infection control measures aimed at patients with identifiable risk factors should trigger prevention, and early detection of nosocomial infections is warranted to further reduce the prevalence of HAIs.

Decreasing Catheter-Associated Urinary Tract Infections in the Neurological Intensive Care Unit: One Unit's Success

BACKGROUND

Catheter-associated urinary tract infections are preventable adverse outcomes that increase hospital morbidity, mortality, and costs. These infections are particularly prevalent in intensive care units.

OBJECTIVES

To describe the success of an 18-bed neurological intensive care unit in using several nurse-implemented strategies that reduced the number of catheter-associated urinary tract infections.

METHODS

A prospective, interventional design with application of evidence-based practices to reduce catheter-associated urinary tract infections was used.

RESULTS

Before implementation of the strategies, 40 catheter-associated urinary tract infections were reported for 2012 and 38 for 2013. The standardized infection ratio was 2.04 for 2012 (95% CI, 1.456-2.775) and 2.34 (95% CI, 1.522-3.312) for 2013. After implementation of the strategies, significantly fewer catheter-associated urinary tract infections were reported. In 2014, a total of 15 infections were reported, and the standardized infection ratio was less than 1.0 (95% CI, 0.685-1.900).

CONCLUSIONS

Application of current evidence-based practices resulted in a substantial decrease in the number of catheter-associated urinary tract infections and a lower standardized infection ratio. These findings support current recommendations for "bundling" to maximize outcomes.

Predictive performance of the American College of Surgeons universal risk calculator in neurosurgical patients

OBJECTIVE

The American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) universal Surgical Risk Calculator is an online decision-support tool that uses patient characteristics to estimate the risk of adverse postoperative events. Further validation of this risk calculator in the neurosurgical population is needed; therefore, the object of this study was to assess the predictive performance of the ACS NSQIP Surgical Risk Calculator in neurosurgical patients treated at a tertiary care center.

METHODS

A single-center retrospective review of 1006 neurosurgical patients treated in the period from September 2011 through December 2014 was performed. Individual patient characteristics were entered into the NSQIP calculator. Predicted complications were compared with actual occurrences identified through chart review and administrative quality coding data. Statistical models were used to assess the predictive performance of risk scores. Traditionally, an ideal risk prediction model demonstrates good calibration and strong discrimination when comparing predicted and observed events.

RESULTS

The ACS NSQIP risk calculator demonstrated good calibration between predicted and observed risks of death (p = 0.102), surgical site infection (SSI; p = 0.099), and venous thromboembolism (VTE; p = 0.164) Alternatively, the risk calculator demonstrated a statistically significant lack of calibration between predicted and observed risk of pneumonia (p = 0.044), urinary tract infection (UTI; p < 0.001), return to the operating room (p < 0.001), and discharge to a rehabilitation or nursing facility (p < 0.001). The discriminative performance of the risk calculator was assessed using the c-statistic. Death (c-statistic 0.93), UTI (0.846), and pneumonia (0.862) demonstrated strong discriminative performance. Discharge to a rehabilitation facility or nursing home (c-statistic 0.794) and VTE (0.767) showed adequate discrimination. Return to the operating room (c-statistic 0.452) and SSI (0.556) demonstrated poor discriminative performance. The risk prediction model was both well calibrated and discriminative only for 30-day mortality.

CONCLUSIONS

This study illustrates the importance of validating universal risk calculators in specialty-specific surgical populations. The ACS NSQIP Surgical Risk Calculator could be used as a decision-support tool for neurosurgical informed consent with respect to predicted mortality but was poorly predictive of other potential adverse events and clinical outcomes.

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.

Epidemiologische Grundlagen nosokomialer Infektionen

Viele Faktoren tragen zu erhöhten nosokomialen Infektionsraten bei. Der Anteil alter Patienten mit chronischen Krankheiten und Immunsupprimierter steigt. Fortschritte in Diagnostik und Therapie resultieren immer häufiger in invasiven Eingriffen. Antibiotikaresistenzen und Folgen nosokomialer Infektionen erfordern daher eine verlässliche Epidemiologie. Konsequenzen nosokomialer Infektionen betreffen einerseits Patienten (Morbidität und Letalität), aber auch das Gesundheitswesen, dem zusätzliche, teilweise vermeidbare finanzielle Belastungen entstehen.

A flowchart for building evidence-based care bundles in intensive care: based on a systematic review

Purpose

The Institute for Healthcare Improvement is the founder of the care bundled approach and described the methods used on how to develop care bundles. However, other useful methods are published as well. In this systematic review, we identified what different methods were used to design care bundles in intensive care units. The results were used to build a comprehensive flowchart to guide through the care bundle design process.

Data sources

Electronic databases were searched for eligible studies in PubMed, EMBASE and CINAHL from January 2001 to August 2014.

Study selection

There were no restrictions on the types of study design eligible for inclusion. Methodological quality was assessed by using the Downs & Black-checklist or Appraisal of Guidelines, REsearch and Evaluation II.

Data extraction

Data extraction was independently performed by two reviewers.

Results of data synthesis

A total of 4665 records were screened and 18 studies were finally included. The complete process of designing bundles was reported in 33% (6/18). In 50% (9/18), one of the process steps was described. A narrative report was written about care bundles in general in 17% (3/18). We built a comprehensive flowchart to visualize and structure the process of designing care bundles.

Conclusion

We identified useful methods for designing evidence-based care bundles. We built a comprehensive flowchart to provide an overview of the methods used to design care bundles so that others could choose their own applicable method. It guides through all necessary steps in the process of designing care bundles.

Avoiding inappropriate urinary catheter use and catheter-associated urinary tract infection (CAUTI): a pre-post control intervention study

Background

Urinary tract infection (UTI) as the most common healthcare-associated infection accounts for up to 36% of all healthcare-associated infections. Catheter-associated urinary tract infection (CAUTI) accounts for up to 80% of these. In many instances indwelling urinary catheter (IDC) insertions may be unjustified or inappropriate, creating potentially avoidable and significant patient distress, embarrassment, discomfort, pain and activity restrictions, together with substantial care burden, costs and hospitalisation. Multifaceted interventions combining best practice guidelines with staff engagement, education and monitoring have been shown to be more effective in bringing about practice change than those that focus on a single intervention. This study builds on a nurse-led initiative that identified that significant benefits could be achieved through a systematic approach to implementation of evidence-based practice.

Methods

The primary aim of the study is to reduce IDC usage rates by reducing inappropriate urinary catheterisation and duration of catheterisation. The study will employ a multiple pre-post control intervention design using a phased mixed method approach. A multifaceted intervention will be implemented and evaluated in four acute care hospitals in NSW, Australia. The study design is novel and strengthened by a phased approach across sites which allows for a built-in control mechanism and also reduces secular effects. Feedback of point prevalence data will be utilised to engage staff and improve compliance. Ward-based champions will help to steward the change and maintain focus.

Discussion

This study will improve patient safety through implementation and robust evaluation of clinical practice and practice change. It is anticipated that it will contribute to a significant improvement in patient experiences and health care outcomes. The provision of baseline data will provide a platform from which to ensure ongoing improvement and normalisation of best practice. This study will add to the evidence base through enhancing understanding of interventions to reduce CAUTI and provides a prototype for other studies focussed on reduction of hospital acquired harms. Study findings will inform undergraduate and continuing education for health professionals.

[Recurrent and catheter-associated urinary tract infections : Prophylaxis and prevention]

Urinay tract infection (UTI) as one of the most frequent bacterial infections in humans is of utmost relevance. Because of the rising prevalence of antimicrobial resistance, urinalysis should always include urine culture and a resistogram in order to avoid an unspecific selection and overuse of antibiotics. Prevention of recurrent UTI must first of all rule out predisposing uropathogenic conditions. Nowadays, a great variety of drugs, behavioral, and supportive treatment options can effectively minimize UTI recurrence. The growing importance of vaccines (immunotherapy), probiotics (lactobacilli), and standardized herbal preparations meets the need of reducing antibiotic use and the development of antimicrobial resistance. Around 80% of all nosocomial UTIs (nUTIs) are associated with indwelling urinary catheters. It is estimated that up to 70% of all nUTIs occurring in Germany may be avoided by using appropriate preventative measures. Therefore, profound knowledge about the basics of catheter-associated nUTIs and the correct management of urinary catheters are of utmost individual and socioeconomic importance.

An intervention to improve the catheter associated urinary tract infection rate in a medical intensive care unit: Direct observation of catheter insertion procedure

BACKGROUND

Healthcare associated infections from indwelling urinary catheters lead to increased patient morbidity and mortality.

AIM

The purpose of this study was to determine if direct observation of the urinary catheter insertion procedure, as compared to the standard process, decreased catheter utilization and urinary tract infection rates.

METHODS

This case control study was conducted in a medical intensive care unit. During phase I, a retrospective data review was conducted on utilsiation and urinary catheter infection rates when practitioners followed the institution's standard insertion algorithm. During phase II, an intervention of direct observation was added to the standard insertion procedure.

RESULTS

The results demonstrated no change in utilization rates, however, CAUTI rates decreased from 2.24 to 0 per 1000 catheter days.

CONCLUSION

The findings from this study may promote changes in clinical practice guidelines leading to a reduction in urinary catheter utilization and infection rates and improved patient outcomes.

Management of infections associated with neurocritical care

The reported incidence of hospital-acquired infections (HAIs) in the neurointensive care unit (NICU) ranges from 20% to 30%. HAIs in US hospitals cost between $28 and $45 billion per year in direct medical costs. These infections are associated with increased length of hospital stay and increased morbidity and mortality. Infection risk is increased in NICU patients due to medication side-effects, catheter and line placement, neurosurgical procedures, and acquired immune suppression secondary to steroid/barbiturate use and brain injury itself. Some of these infections may be preventable but many are not. Their appearance do not always constitute a failure of prevention or physician error. Neurointensivists require indepth knowledge of common nosocomial infections, their diagnosis and treatment, and an approach to evidence-based practices that improve processes of care and reduce HAIs.

External Collection Devices as an Alternative to the Indwelling Urinary Catheter: Evidence-Based Review and Expert Clinical Panel Deliberations

Multiple evidence-based guidelines have suggested clinicians consider external collection devices (ECD) as alternatives to indwelling catheters. Nevertheless, there is a dearth of evidence-based resources concerning their use. An expert consensus panel was convened to review the current state of the evidence, indications for ECDs as an alternative to an indwelling urinary catheter, identify knowledge gaps, and areas for future research. This article presents the results of the expert consensus panel meeting and a systematic literature review regarding ECD use in the clinical setting.

Length of hospital stay after craniotomy for tumor: a National Surgical Quality Improvement Program analysis

OBJECT

Although the length of hospital stay is often used as a measure of quality of care, data evaluating the predictors of extended hospital stay after craniotomy for tumor are limited. The goals of this study were to use multivariate regression to examine which preoperative characteristics and postoperative complications predict a prolonged hospital stay and to assess the impact of length of stay on unplanned hospital readmission.

METHODS

Data were extracted from the National Surgical Quality Improvement Program (NSQIP) database from 2007 to 2013. Patients who underwent craniotomy for resection of a brain tumor were included. Stratification was based on length of hospital stay, which was dichotomized by the upper quartile of the interquartile range (IQR) for the entire population. Covariates included patient age, sex, race, tumor histology, comorbidities, American Society of Anesthesiologists (ASA) class, functional status, preoperative laboratory values, preoperative neurological deficits, operative time, and postoperative complications. Multivariate logistic regression with forward prediction was used to evaluate independent predictors of extended hospitalization. Thereafter, hierarchical multivariate logistic regression assessed the impact of length of stay on unplanned readmission.

RESULTS

The study included 11,510 patients. The median hospital stay was 4 days (IQR 3-8 days), and 27.7% (n = 3185) had a hospital stay of at least 8 days. Independent predictors of extended hospital stay included age greater than 70 years (OR 1.53, 95% CI 1.28%-1.83%, p < 0.001); African American (OR 1.75, 95% CI 1.44%-2.14%, p < 0.001) and Hispanic (OR 1.68, 95% CI 1.36%-2.08%) race or ethnicity; ASA class 3 (OR 1.52, 95% CI 1.34%-1.73%) or 4-5 (OR 2.18, 95% CI 1.82%-2.62%) designation; partially (OR 1.94, 95% CI 1.61%-2.35%) or totally dependent (OR 3.30, 95% CI 1.95%-5.55%) functional status; insulin-dependent diabetes mellitus (OR 1.46, 95% CI 1.16%-1.84%); hematological comorbidities (OR 1.68, 95% CI 1.25%-2.24%); and preoperative hypoalbuminemia (OR 1.78, 95% CI 1.51%-2.09%, all p ≤ 0.009). Several postoperative complications were additional independent predictors of prolonged hospitalization including pulmonary emboli (OR 13.75, 95% CI 4.73%-39.99%), pneumonia (OR 5.40, 95% CI 2.89%-10.07%), and urinary tract infections (OR 11.87, 95% CI 7.09%-19.87%, all p < 0.001). The C-statistic of the model based on preoperative characteristics was 0.79, which increased to 0.83 after the addition of postoperative complications. A length of stay after craniotomy for tumor score was created based on preoperative factors significant in regression models, with a moderate correlation with length of stay (p = 0.43, p < 0.001). Extended hospital stay was not associated with differential odds of an unplanned hospital readmission (OR 0.97, 95% CI 0.89%-1.06%, p = 0.55).

CONCLUSIONS

In this NSQIP analysis that evaluated patients who underwent craniotomy for tumor, much of the variance in hospital stay was attributable to baseline patient characteristics, suggesting length of stay may be an imperfect proxy for quality. Additionally, longer hospitalizations were not found to be associated with differential rates of unplanned readmission.

The Ann Arbor Criteria for Appropriate Urinary Catheter Use in Hospitalized Medical Patients: Results Obtained by Using the RAND/UCLA Appropriateness Method

Interventions to reduce urinary catheter use involve lists of "appropriate" indications developed from limited evidence without substantial multidisciplinary input. Implementing these lists, however, is challenging given broad interpretation of indications, such as "critical illness." To refine criteria for appropriate catheter use-defined as use in which benefits outweigh risks-the RAND/UCLA Appropriateness Method was applied. After reviewing the literature, a 15-member multidisciplinary panel of physicians, nurses, and specialists in infection prevention rated scenarios for catheter use as appropriate, inappropriate, or of uncertain appropriateness by using a standardized, multiround rating process. The appropriateness of Foley catheters, intermittent straight catheters (ISCs), and external condom catheters for hospitalized adults on medical services was assessed in 299 scenarios, including urinary retention, incontinence, wounds, urine volume measurement, urine sample collection, and comfort. The scenarios included patient-specific issues, such as difficulty turning and catheter placement challenges. The panel rated 105 Foley scenarios (43 appropriate, 48 inappropriate, 14 uncertain), 97 ISC scenarios (15 appropriate, 66 inappropriate, 16 uncertain), and 97 external catheter scenarios (30 appropriate, 51 inappropriate, 16 uncertain). The refined criteria clarify that Foley catheters are appropriate for measuring and collecting urine only when fluid status or urine cannot be assessed by other means; specify that patients in the intensive care unit (ICU) need specific medical indications for catheters because ICU location alone is not an appropriate indication; and recognize that Foley and external catheters may be pragmatically appropriate to manage urinary incontinence in select patients. These new appropriateness criteria can inform large-scale collaborative and bedside efforts to reduce inappropriate urinary catheter use.
