Standardized Infection Ratio Research Articles

Closing the gap on infection prevention staffing recommendations: Results from the beta version of the APIC staffing calculator.

Published literature suggests "one-size-fits-all" infection prevention and control (IPC) staffing recommendations do not sufficiently account for program complexity needs. This project's objective was to create and validate a calculator utilizing risk and complexity factors to generate individualized IPC staffing ratios. An online survey-based calculator was created that incorporated factors intended to predict staffing needs and multiple investigative questions to allow for optimization of factors in the algorithm. Hospital characteristics, staffing ratios, staffing perception, and outcomes were analyzed to determine the optimal questions and benchmarks for future releases. The median infection preventionist full-time equivalent to bed ratio was 121.0 beds for 390 participating hospitals. The calculator deemed 79.2% of respondent staffing as below expected. Significant association existed between higher standard infection ratio ranges and staffing status for central line-associated bloodstream infection (P=.02), catheter-associated urinary tract infections (P=.001), Clostridioides difficile infections (P=.003), and colon surgical site infections (P=.0001). This novel approach allows facilities to staff their IPC program based on individual factors. Future versions of the calculator will be optimized based on the findings. Future research will clarify the impact of staffing on patient outcomes and staff retention.

Developing and reporting a healthcare-associated infection composite score for health system board review

Background One strategy for supporting a hospital or health system's board of directors (Board), with their quality oversight responsibility is to review the organization's performance on quality measures. But for large systems, the number of measures needing review is quite burdensome and makes priority setting difficult. Our goal was to develop a scoring method that summarizes multiple quality measures together, while still maintaining the Board's opportunity to examine individual measures where there are specific concerns. Methods We calculated an overall health system-level composite performance score using six publicly reported healthcare-associated infections reported by the Centers for Medicare and Medicaid Services on their Care Compare website [central-line associated bloodstream infections (CLABSI), catheter-associated urinary tract infections (CAUTI), surgical site infections (SSIs) for colon surgery and abdominal hysterectomy, hospital-onset Methicillin-resistant Staphylococcus aureus bacteremia (MRSA), and hospital-onset Clostridioides difficile ( C. diff)], where relative weights assigned to each infection type reflect the severity of patient harm. We also calculated a health-system composite performance target. For individual infection types, we calculated system-wide scores and targets and categorized individual hospital performance into three performance categories. Results The health system's composite score between 2015 and 2019 ranged from a high of 1.10 to a low of 0.71. The health system's composite score in 2017–2019 was better than the composite target. Of the 34 measures used to calculate the 2019 composite score, 20 were better than internal standardized infection ratio (SIR) targets, seven were between internal targets and SIR of 1.0, and seven were worse than SIR of 1.0. Discussion The Board communicated they find this composite score reporting approach helpful for streamlining their understanding of HAI performance, as compared to traditional approaches of reporting out individual performance measures. Approaches that streamline Board review of quality and safety performance are important as we hold Board members accountable for overseeing quality, seek greater engagement from the Board, and work to minimize measure review overload.

An Analysis of the Standardized Infection Ratio in California from 2015 to 2019: A Publicly Reported, Validated Measure of Hospital Case-mix Complexity and Quality for Surgical Site Infections in Hip Arthroplasty

The Standardized Infection Ratio (SIR), developed by the National Healthcare Safety Network (NHSN), is a validated healthcare quality outcome measure utilized by the California Department of Public Health (CDPH). Our primary goal was to use information from the SIR as measures of risk-adjusted surgical case-mix complexity and Healthcare Associated Infection (HAI) quality for surgical site infections (SSIs) in hip prosthesis (HPRO) surgery. We acquired NHSN SSI data files for HPRO surgery from 330 acute care hospitals. We categorized hospitals into 5 types (teaching, rural, community low volume, community medium volume, and community high volume) and sorted hospitals by procedure count, generating volume terciles. We multiplied each SIR and 95% confidence limits by a scale factor to allow for a comparison to the average SIR in California for the study period. The highest and lowest expected infection rates (case-mix complexity) were found in teaching hospital (0.86%) and community, high- volume hospitals (0.56%). When all non-teaching hospitals were combined, teaching hospitals treated a higher case complexity (95% Confidence Limit (CL): 0.7713 to 0.9727) than non-teaching hospitals (95% CL 0.5774, 0.6518). The lowest and highest SIR values were seen in community high volume (0.78) and rural hospitals, (1.38). The lowest- volume hospitals performed significantly worse (SIR 1.15: 95%CL 1.058-1.256) than the highest- volume hospitals (SIR 0.83: 95% CL 0.747-0.920). The SIR model developed by NHSN provides important public information about risk-adjusted surgical case-mix complexity and hospital quality for SSIs that incorporates parameters that may more accurately account for technical challenges in HPRO surgery.

Implementing a Compliance Monitoring Process to Promote Chlorhexidine Gluconate Bathing and Hand Hygiene: An Initiative to Decrease Central Line–Associated Bloodstream Infections

Background Chlorhexidine gluconate (CHG) bathing has proven to reduce central line–associated bloodstream infections (CLABSI) in hospitalized patients. The aim of this study is to evaluate whether the implementation of a compliance monitoring process for CHG bathing and strict hand hygiene as part of the traditional CLABSI prevention bundle will reduce the overall hospital CLABSI standardized infection ratio (SIR). Methods A quasi-experimental study was conducted in intensive care and non-intensive care inpatient hospital units in an urban 361-bed teaching hospital in Western Pennsylvania. The pre-intervention period consisted of January–August 2021, the intervention period consisted of September–November 2021, and the post-intervention and sustainability period consisted of December 2021–June 2022. A compliance monitoring process for the initiation of a daily bath using a 4% CHG solution and strict hand hygiene surveillance was implemented as part of the standard CLABSI prevention bundle (which includes standardized insertion checklists and processes, daily necessity assessment, dressing change and integrity standards, five moments hand hygiene standards, CHG disk [Biopatch], end caps [Curos], and care of tubing). Outcomes A statistically significant increase in hand hygiene (p=<0.001) and in CHG bathing compliance (p=0.014) helped reduce the overall hospital CLABSI SIR from 1.45 to 0.82, standing for an overall 43.4% decrease. Cost reduction was statistically significant (p=0.011) and was an estimated $1.4 million dollars in savings for the hospital. Next Steps Incorporate the compliance monitoring component for CHG bathing and hand hygiene as part of the best strategy for CLABSI bundle prevention within the healthcare system.

Choice of needleless connector technology as a risk reduction strategy for catheter related bloodstream infection, mortality, and cost: A secondary data analysis.

To compare relative risk (RR) of central line-associated bloodstream infection (CLABSI) between hospitals using Clave needleless connector technologies (NCT) and comparator hospitals using non-Clave NCT. And, to estimate avoided CLABSIs, mortality, and cost savings. Needleless connectors, while protective against needlestick injury, have long been implicated as a potential risk for CLABSI. Significant RR reduction of CLABSI among the many NCT has not been clinically demonstrated. The U.S. Healthcare-Associated Infections database was accessed for CLABSI data for calendar year 2019 via the Centers for Medicare and Medicaid Services website. This dataset was merged with the Clave NCT manufacturer's 2019 database to identify hospitals purchasing Clave NCT (MicroClave™, NanoClave™, Clave Neutron™, Clave™, Microclave™ Clear) and non-Clave NCT comparator hospitals. Sub-analysis of Clave NCT hospitals included: (1) Clave NCT mixed-use and (2) Clave high-volume use hospitals. The standardized infection ratio (SIR) was generated to estimate CLABSI RR after adjusting for intern/resident-to-bed-ratio (IRB), care location, and hospital demographics. Using the RR, avoided CLABSIs, mortality, and cost savings were calculated. A total of 2987 eligible hospitals (1288 Clave NCT, 1699 non-Clave NCT) with 17,452,575 central line-days were evaluated. All three Clave NCT hospital groups showed a statistically significant reduction in RR compared to the non-Clave NCT hospitals. The RR in Clave NCT hospitals was 0.93, a 7% decrease in CLABSI risk (p = 0.02). In the Clave NCT subgroups, mixed-use hospitals RR was 0.93, a 7% reduction (p = 0.04), while the Clave NCT high-volume hospitals experienced a 19% reduction, RR 0.81 (p = 0.04). An estimated 563 CLABSIs and 84 related deaths were avoided with use of Clave NCT and $27,095,231 in cost savings. The use of the Clave NCT, in and of itself, is an effective risk reduction strategy for CLABSI prevention, reduced mortality, and substantial cost savings.

Impact of Vascular Access Teams on Central Line Associated Bloodstream Infections

Background: During the COVID-19 pandemic, rates of central line bloodstream infections (CLABSI) increased nationally. Studies pre-pandemic showed improved CLABSI rates with implementation of a standardized vascular access team (VAT).[PL1] [PL2] [mi3] Varying VAT resources and coverage existed in our 10 acute care facilities (ACF) prior to and during the pandemic. VAT scope also varied in 1) process for line selection during initial placement, 2) ability to place a peripherally inserted central catheter (PICC), midline or ultrasound-guided peripheral IV in patients with difficult vascular access, 3) ownership of daily assessment of central line (CL) necessity, and 4) routine CL dressing changes. We aimed to define and implement the ideal VAT structure and evaluate the impact on CLABSI standardized infection ratios (SIR) and rates prior to and during the pandemic. Methods: A multidisciplinary workgroup including representatives from nursing, infection prevention, and vascular access was formed to understand the current state of VAT responsibilities across all ACFs. The group identified key responsibilities a VAT should conduct to aid in CLABSI prevention. Complete VAT coverage[mi4] was defined as the ability to conduct the identified responsibilities daily. We compared the SIR and CLABSI rates between hospitals who had complete VAT (CVAT) coverage to hospitals with incomplete VAT (IVAT) coverage. Given this work occurred during the pandemic, we further stratified our analysis based on a time frame prior to the pandemic (1/2015 – 12/2019) and intra-pandemic (1/2020 - 12/2022). Results: The multidisciplinary team identified 6 key components of complete VAT coverage: Assessment for appropriate line selection prior to insertion, ability to insert PICC and midlines, daily CL and midline care and maintenance assessments, daily assessment of necessity for CL, and weekly dressing changes for CL and midlines[NA5] . A cross walk of VAT scope (Figure 1) was performed in October 2022 which revealed two facilities (A and E) which met CVAT criteria. Pre-pandemic, while IVAT CLABSI rates and SIR were higher than in CVAT units, the difference was not statistically significant. During the pandemic, however, CLABSI rates and SIR were 40-50% higher in IVAT compared to CVAT facilities (Incident Rate Ratio 1.5, 95% CI 1.1-2.0 and SIR Relative Ratio 1.4, 95% CI1.1-1.9 respectively) (Table 1). Conclusions: CLABSI rates were lower in facilities with complete VAT coverage prior to and during the COVID-19 pandemic suggesting a highly functioning VAT can aid in preventing CLABSIs, especially when a healthcare system is stressed and resources are limited.

Breaking the Reflex: Impact in Hospital-Acquired Infection Incidence for Clostridioides difficile Infection

Background: Nucleic acid amplification tests (NAAT) do not distinguish between colonization and Clostridioides difficile (C.diff) associated diarrhea. On April 5th 2023 our laboratory introduced a new C. diff testing methodology. Previously, if a C. diff screen result was negative for toxin and positive for glutamate dehydrogenase (GDH), a second confirmatory test was conducted with NAAT. This confirmatory test was removed from our testing algorithm. NAAT testing may be ordered ad hoc when clinically relevant diarrhea persists, and alternative etiologies have been excluded. We wanted to evaluate the impact of change with testing methods. Method: Retrospective review of all inpatient hospital-acquired C.diff infections reported to NHSN database from Ascension Michigan Market which comprises 14 acute care hospitals from June 2019 to August 2023. Data for C diff was analyzed every quarter. The risk adjustments used to calculate the Standardized Infection Ratios (SIRs) for C. diff infections was set at 0.48 based on CDC mean SIR established for acute care hospitals in 2022. Results: A total of 14 acute care hospitals were included from which 866 C.diff cases were reported during this period. Overall, the SIR dropped from 0.59 from June-August 2019 to 0.32 reported from March-May 2023; 45.7 % decrease. The maximum reduction in SIR was seen post intervention at 0.21 from June-August 2023 which was 78.3% below the benchmark of 0.48. (Figure) Conclusions: Strategies to optimize current laboratory tests are critical to differentiate C. diff infection from colonization. The current strategy by changing the testing method led to substantial reduction in C-diff. Diagnostic stewardship studies should ideally include outcome measures targeted to post-intervention patients to determine clinical relevance and patient safety. Optimizing test utilization remains a critical component of quality healthcare delivery. Future NHSN updated surveillance definition will require incorporating clinical decision-making into the metric; that is including a combination of any positive C-diff test plus initiation of antibiotic therapy for C-diff.Disclosure: Reese Cosimi: Advisory Board - Abbvie

A Deeper Look at Proposed Surveillance of Superficial Incision Surgical Site Infections (SSISSIs)

Although the National Healthcare Safety Network (NHSN) recommends the reporting of superficial incisional SSIs, the standardized infection ratio (SIR) models used by the NSHN exclude superficial incisional SSIs cases. Yet, some superficial incisional SSIs may lead to serious adverse patient outcomes. We previously proposed a new category of such infections: serious superficial incisional surgical site infections (SSISSIs), defined as a superficial incisional SSI that (1) required debridement in an operating room and/or (2) led to a hospital readmission within 30 days of surgery. The objective of our study was to determine the prevalence of SSISSIs in a large network of community hospitals and compare hospital rankings of SSI rates of organ/space and deep SSIs (complex SSIs) with and without SSISSIs. We performed a retrospective descriptive analysis of prospectively collected data on 35 NHSN surgical categories in 47 community hospitals within the Duke Infection Control Outreach Network (DICON) from 1/1/2013-12/31/2022. All hospitals used standardized surveillance and data collection strategies throughout the study period. The Wilcoxon rank-sum was used to test for differences in performance rankings of hospitals sorted by rates of complex SSIs alone compared to complex and SSISSI rates. A two-tailed P value of .05 or less was considered significant. Overall, 11,617 SSIs occurred after 1,272,257 surgeries (0.91 SSIs/100 procedures). Out of 3,996 superficial SSIs, 2,038 (17.5% overall, 51.0% of superficial incisional) met criteria for SSISSI. 112 (5.5%) were diagnosed during the current admission and required takeback to the OR for infection; 1,926 (94.5%) were diagnosed during a readmission; and 3841 (33.1%) were diagnosed during readmission and returned to the OR. (Table1) The highest proportion of SSISSIs was diagnosed in patients who underwent gastrointestinal surgery (32.0%) or orthopedic surgery (24.0%). (Table2) Performance ranking of individual hospitals based on rates of complex SSIs, differed significantly when including SSISSIs (p= 0.02). (Table3) Discussion Our findings suggest that SSISSIs make up a moderate but important proportion of SSIs in community hospitals. SSISSIs can be identified through established database surveillance looking at objective measures of returning to the OR for debridement and/or readmission within 30 days. Hospital rankings differed significantly when SSISSIs were added to complex SSIs to calculate SSI rates. As such, including SSISSIs likely provides a more accurate depiction of SSIs with important outcomes and is not as subjective to surveillance bias. Next steps would be specifically to look at outcomes data for complex SSIs compared to SSISSIs to fully evaluate theDisclosure: Jessica Seidelman: UptoDate- Section Editor; BoneSupport- Consultant

Impact and Safety of Diagnostic Stewardship to Improve Urine Culture Testing Among Patients with Indwelling Urinary Catheters

Background: Indiscriminate urine culturing of patients with indwelling urinary catheters may lead to overdiagnosis of urinary tract infections, resulting in unnecessary antibiotic treatment and inaccurate reporting of catheter-associated urinary tract infections (CAUTIs) as a hospital quality metric. We evaluated the impact of a computerized diagnostic stewardship intervention to improve urine culture testing among patients with indwelling urinary catheters. Methods: We performed a single-center retrospective observational study at Rush University Medical Center from April 2018 – July 2023. In February 2021, we implemented a computerized clinical decision support tool to promote adherence to our internal urine culture guidelines for patients with indwelling urinary catheters. Providers were required to select one guideline criteria: 1) neutropenia, 2) kidney transplant, 3) recent urologic procedure, 4) urinary tract obstruction; or if none of the criteria were met, then an infectious diseases consultation was required for approval. We compared facility-wide CAUTI rate per 10,000 catheter days and standardized infection ratio (SIR) during baseline and intervention periods using ecologic models, controlling for time and for monthly Covid-19 hospitalizations. In the intervention period, we evaluated how providers responded to the intervention. Potential harm was defined as collection of a urine culture within 7 days of the intervention that resulted in a change in clinical management. Results: In unadjusted models, CAUTI rate decreased from 12.5 to 7.6 per 10,000 catheter days (p=0.04) and SIR decreased from 0.77 to 0.49 (p=0.09) during baseline vs intervention periods. In adjusted models, the CAUTI rate decreased from 6.9 to 5.5 per 10,000 catheter days (p=0.60) (Figure 1) and SIR decreased from 0.41 to 0.35 (p=0.65) during baseline vs intervention periods. Urine catheter standard utilization ratio (SUR) did not change (p=0.36). There were 598 patient encounters with ≥1 intervention. Selecting the first intervention for each encounter, 284 (47.5%) urine cultures met our guidelines for testing and 314 (52.5%) were averted (Figure 2). Of these, only 3 ( < 1 %) had a urine culture collected in the subsequent 7 days that resulted in change in clinical management. Conclusion: We observed a trend of decreased CAUTIs over time, but effect of our diagnostic stewardship intervention was difficult to assess due to healthcare disruption caused by Covid-19. Adverse outcomes were rare among patients who had a urine culture averted. A computerized clinical decision support tool may be safe and effective as part of a multimodal program to reduce unnecessary urine cultures in patients with indwelling urinary catheters.

Successful practices to reduce central line–associated bloodstream infections post pandemic: A qualitative study

Central Line-Associated Bloodstream Infections (CLABSIs) decreased in U.S. hospitals over the last decade, but CLABSI rates increased during the COVID-19 pandemic disrupting the downward trend. This study explored factors contributing to the reduction of CLABSI, identifying deviations in infection prevention and control protocol during the pandemic, actions taken to address the increase in CLABSI, and factors promoting sustained progress. This qualitative study used the National Healthcare Safety Network data. The Centers for Disease Control and Prevention identified hospitals with elevated CLABSI standardized infection ratios (SIR) >1 between Q1 2019 - Q4 2021 followed by four quarters of sustained reduction (CLABSI SIR <1). Joint Commission researchers conducted semi-structured phone interviews with infection preventionist professionals from six hospitals representing these performance patterns. Interview themes suggested that staffing shortages (83%) and less vigilant central line practices (100%) contributed to increased CLABSI SIR during the pandemic. Organizations described evidence-based interventions, such as using chlorhexidine gluconate for skin preparation, along with other innovative strategies they used to establish reduced CLABSI rates. Despite challenges faced during the COVID-19 pandemic, some health care organizations have excelled in their efforts to reduce and sustain low rates of CLABSI by implementing evidence-based practices, innovative solutions, and education.

Infection prevention making a difference on statewide standardized infection ratios for device-associated HAIs from 2015-2022

Background: Central line-associated bloodstream infections (CLABSIs) and catheter-associated urinary tract infections (CAUTIs) cause significant morbidity and mortality among hospitalized patients. Over the last 10 to 20 years, hospital accountability for the prevention of device-associated infections increased at the state and national levels. For example, the Centers for Medicare &amp; Medicaid Services implemented the Hospital Inpatient Quality Reporting Program in 2015. The objective of this study was to assess the impact of increased federal attention on infection prevention using longitudinal data from the National Healthcare Safety Network (NHSN). We hypothesize that there was a significant decrease in statewide standardized infection ratios (SIRs) for CLABSI and CAUTI over the last 8 years. Methods: We collected SIRs for CLABSI and CAUTI in acute care hospitals for all 50 states and Washington D.C. from the NHSN database from 2015 to 2022. For CLABSI, we performed unique analyses for critical care units, wards, and neonatal intensive care (NICU) locations. For CAUTI, we stratified by critical care units and wards. We included all states with more than 5 hospitals reporting data. Those with fewer than 5 were excluded by listwise deletion in the corresponding analysis. We tested trends over time using linear mixed effect models with year as fixed effect and state as random effect. We also included an indicator variable representing the influence of SARS-CoV-2 (Covid-19) on healthcare-associated infections (HAIs). We elected an alpha of 0.05 as the threshold for statistical significance. Results: Overall, CLABSI and CAUTI SIRs exhibited significant negative slopes (Figures 1-5) after controlling for the influence of Covid-19. Each analysis revealed progressively lower SIRs compared to the previous year except for the 2019-2020 interval. Interestingly, the linear trend resumed after 2020 with subsequently lower SIRs in 2021 and 2022. Covid-19 had a greater influence on CLABSI SIRs in critical care settings compared to ward or NICU locations. The slope of CAUTI SIRs were impacted less by Covid-19 in wards compared to critical care settings. Conclusion: The results of the analysis demonstrate that CLABSI and CAUTI are trending in the desired direction despite the HAI spike during Covid-19. Government and hospital stakeholders in the United States should be encouraged by the reported trends and continue to prioritize the funding and use of resources for evidence-based device-associated infection prevention.

Aiming for Zero: Success of the Hysterectomy Surgical Site Infection Prevention Bundle

Background: The Center for Disease Control’s National Healthcare Safety Network (NHSN) reported an increased Standardized Infection Ratio (SIR) at a large community hospital, calculated by the number of observed infections over the number of predicted infections. In response to the increased SIR, a multidisciplinary Hysterectomy Surgical Site Infection (SSI) Prevention Workgroup was formed in 2019. Objective: To promote a surgical site infection prevention bundle that was implemented at a large community hospital to reduce hysterectomy associated surgical site infections. Study Design: The Workgroup implemented an evidence-based Hysterectomy SSI Prevention Bundle which enforced standardization of measures and techniques at: The pre-operative clinic appointment, the day of surgery, the intra-operative time prior to incision, the intra-operative time from incision to closure, and in the immediate post-operative recovery. The Hysterectomy SSI Prevention Bundle was implemented November 2, 2020. This study included all hysterectomies for benign pathologies from 10/1/2018 to 9/30/2020 [pre-implementation (n=811)] and 1/1/2021 to 9/30/2022 [post-implementation (n=772)]. Per NHSN data categorization guidelines, a designation of abdominal hysterectomy includes both open and laparoscopic routes. Inpatient surgery was defined as that with a date of discharge different from date of operation; outpatient surgery was defined as the one with the same date of discharge. SSIs included superficial, deep and organ/space, while complex SSIs included deep and organ/space. Patient demographics were categorized and evaluated for statistical significance. Results: After implementation of the SSI bundle, SIR for hysterectomies was reduced to &lt; 1.0, indicating infection prevention. Outpatient abdominal hysterectomy SIR pre-implementation was 2.551 and post-implementation was 0.868 (p=0.007). The outpatient vaginal hysterectomy SIR pre-implementation was 0, and post-implementation remained 0 (p=0.364). Inpatient abdominal hysterectomy SIR pre-implementation was 1.554 and post-implementation was 0.443 (p=0.072). The inpatient vaginal hysterectomy SIR preimple-mentation was 1.064, and post-implementation was 0 (p &lt;0.001). The inpatient complex abdominal hysterectomy SIR pre-implementation was 1.757 and post-implementation was 0 (p=0.040). The inpatient complex vaginal hysterectomy SIR pre-implementation was 1.001, and post-implementation was 0 (p &lt;0.001). Differences between the pre- and post-implementation groups were significant for increased laparoscopic hysterectomies (p&lt;0.001), decreased vaginal hysterectomies (p&lt;0.001), increased number of same day discharges (p&lt;0.001), longer procedure duration (p&lt;0.001), and younger age (p=0.039). Conclusion: Implementation of an evidence-based surgical site infection prevention bundle at a large community hospital has significantly reduced SIR for inpatient vaginal hysterectomies, outpatient abdominal hysterectomies, and all inpatient complex hysterectomies.

A Collaborative Quality Improvement Project to Reduce Surgical Site Infection in Cesarean Delivery.

Cesarean delivery (CD) facilitates delivery of the baby through an incision and is performed in situations where vaginal delivery poses risks to the mother, baby, or both. Over 1.2 million CDs are performed in the United States annually. An interdisciplinary council was created to drive regular data analysis and sharing, interdisciplinary collaboration, and standardized processes to reduce surgical site infections (SSI) following CD. The standardized infection ratio (SIR), a summary measure used to track hospital-acquired infections at a national, state, or local level over time, was used. Bundle components included pre- and postsurgical education and access to follow-up, peri- and intraoperative practice changes, and a risk stratification tool for postoperative dressing selection. The bundle was initiated in April 2022. After use was established for 6 months, the SIR was evaluated in the fourth quarter of 2022. For this one quarter, the expected SIR for the hospital was 2.64, and the calculated SIR measured 0.38. In 2022, which included 3 months prebundle and 9 months postbundle, the expected SIR was 10.57, with a calculated SIR of just 0.66 for the full year. In 2023, the expected SIR was 11.10, with a calculated SIR of 0.27. The SSI rate reflects an observed 75% reduction in SSI between the years 2021 and 2023. Zero SSI have been observed from January to May 2024. For the patients who underwent planned CD, 98% received the full perioperative obstetric bundle. The ongoing analysis and sharing of data, the implementation of standardized processes, and interdisciplinary collaboration were imperative to the success of this hospital's quality improvement project to reduce SSI for patients undergoing CD.

Implementation of a multi-modal intervention adopting new technologies, clinical services, and feedback improves catheter-associated urinary tract infections

ABSTRACT Objectives Catheter-associated urinary tract infections (CAUTI) are a significant cause of morbidity and financial burden to healthcare systems. The aim of this study was to develop and implement a program designed to reduce Foley catheter use days and associated CAUTI rates. Methods A retrospective evaluation of a multi-modal program aimed toward reducing Foley catheter use days and associated CAUTI rates across the Indiana University Health (IUH) system was conducted. IUH is comprised of 16 hospitals and 2,703 available beds. The program included the adoption of new technologies with evidence-based clinical training materials based on change management and feedback from clinicians. National Healthcare Safety Network Standardized Infection Ratio (SIR), Standardized Utilization Ratio (SUR), and Incidence Density Ratio (IDR) rates were assessed. Results Implementation of the multi-modal program resulted in a significant reduction in SIR, SUR, and IDR in the post-implementation compared to the baseline periods. Conclusions Through CAUTI bundle workflow assessments, education, and interventions designed to standardize practice variation, the program was successfully implemented and resulted in a significant decrease in Foley Catheter use days, and associated CAUTI rates.

Hemodialysis-Related Infections: A 4-Year Surveillance

Objective: To analyze the results from the surveillance of hemodialysis-related infections.Material and Methods: Data was prospectively gathered from outpatients attending a hemodialysis unit from April 2019 until March 2023. The National Healthcare Safety Network (NHSN) Dialysis Event Surveillance was used to identify three types of infection-related dialysis events. Event rates were calculated and stratified by vascular access type, standardized infection ratios for bloodstream infections (BSI), intravenous antimicrobial starts, and described pathogens identified among BSI.Results: A total of 2,288 patient-month follow-ups were included. There were 79 infection-related dialysis events (24 BSI; 46 intravenous antimicrobial starts, nine pus, redness, or increased swelling at the vascular access site). The incidence of BSI per 100 patient-months was 1.05 (0.59 arteriovenous fistula, 0.83 arteriovenous graft, and 2.22 central venous catheter). Seventeen BSI were vascular access-related. Access-related BSI per 100 patient-months was 0.74 (0.39 arteriovenous fistula, 0.41 arteriovenous graft, and 1.85 central venous catheter). Intravenous antimicrobial starts per 100 patient-months was 2.01 (0.98 arteriovenous fistula, 2.62 arteriovenous graft, and 3.14 central venous catheter). Most events occurred in patients with a central venous catheter. When benchmarked with the 2014 NHSN, the standardized infection ratio of BSI, access-related BSI, and intravenous antimicrobial starts were 1.40, 1.26, and 0.55, respectively. The most serious outcome was BSI; resulting in 83.3% hospitalizations, 25% loss of vascular access, and 15.8% deaths. Conclusion: Surveillance of infection-related dialysis events is important for prevention. These events were highest among patients with a central venous catheter compared with other vascular access types.

Sprint Team Approach Yields Rapid Improvement in Leapfrog Quality Indicators.

Patient safety and quality care are two critical areas that every healthcare organization strives to grow and improve upon. At Scripps Health, specific efforts reviewed for this article were implemented to reduce hospital-acquired conditions and hospital readmissions that are components of Centers for Medicare & Medicaid Services programs and Leapfrog Hospital Survey scores. Sprint teams, a novel approach to rapidly develop a checklist for lower-performing care improvement areas, were implemented after an internal review of existing tools and an evidence-based literature review. These areas included catheter-associated urinary tract infections (CAUTIs), central-line associated bloodstream infections (CLABSIs), Clostridioides difficile (C. diff.) and methicillin-resistant Staphylococcus aureus (MRSA) infections, chronic obstructive pulmonary disease (COPD) and heart failure readmissions, surgical site infections and handwashing, bar coding, and the computerized physician order entry components of Leapfrog scoring. The checklist for each area served as a teaching tool for staff and a guideline for case review to ensure that standard work was routinely performed. The sprint teams showed dramatic results in the initial focus areas. From a baseline standardized infection ratio (SIR) of 1.141 for CLABSIs, the sprint team reduced the SIR to 0.885 in Year 1 of the program and to 0.687 in Year 2. For CAUTIs, the SIR decreased from a baseline of 1.391 in Year 1 to 0.720 in Year 2. C. diff. infections fell from 0.422 to 0.315 in Year 1 and to 0.260 in Year 2. While the MRSA SIR did not improve during the first year, the MRSA reduction sprint team showed success in Year 2 with a decrease in the SIR from 0.537 to 0.245. Readmission reduction sprint teams focused on heart failure, COPD, and total hip and knee complications. The teams also achieved positive results in reducing readmissions by following checklists and reviewing each readmission case for justification. Rapid change can be safely and effectively implemented with multidisciplinary sprint teams. Developed with an evidence-based, case review approach, sprint team checklists can help to standardize processes for the review of any infections or readmissions that occur in the inpatient arena.

Effect of Standardized Bundle Care and Bundle Compliance on Reducing Surgical Site Infections: A Pragmatic Retrospective Cohort Study.

BACKGROUND Care bundles for infection control consist of a set of evidence-based measures to prevent infections. This retrospective study aimed to compare surgical site infections (SSIs) from a single hospital surveillance system between 2017 and 2020, before and after implementing a standardized care bundle across specialties in 2019. It also aimed to assess whether bundle compliance affects the rate of SSIs. MATERIAL AND METHODS A care bundle consisting of 4 components (peri-operative antibiotics use, peri-operative glycemic control, pre-operative skin preparation, and maintaining intra-operative body temperature) was launched in 2019. We compared the incidence rates of SSIs, standardized infection ratio (SIR), and clinical outcomes of surgical procedures enrolled in the surveillance system before and after introducing the bundle care. The level of bundle compliance, defined as the number of fully implemented bundle components, was evaluated. RESULTS We included 6059 procedures, with 2010 in the pre-bundle group and 4049 in the post-bundle group. Incidence rates of SSIs (1.7% vs 1.0%, P=0.013) and SIR (0.8 vs 1.48, P<0.01) were significantly lower in the post-bundle group. The incidence of SSIs was significantly lower when all bundle components were fully adhered to, compared with when only half of the components were adhered to (0.3% vs 4.0%, P<0.01). CONCLUSIONS SSIs decreased significantly after the application of a standardized care bundle for surgical procedures across specialties. Full adherence to all bundle components was the key to effectively reducing the risk of surgical site infections.
