This study aimed to summarize the sociodemographic characteristics of eligible HCP in Oregon and estimate vaccine effectiveness (VE) of a mRNA COVID-19 vaccine booster dose.Methods: Using a case-control design, we compared HCP with positive antigen or nucleic acid amplification test SARS-CoV-2 test results (cases) to those with negative results (controls) and matched by site and test date. Using conditional logistic regression adjusted for age, sex, race and ethnicity, educational level, underlying conditions, and exposure to COVID-19, we estimated VE for a third COVID-19 vaccine booster dose using the screening method as 1-odds ratio × 100%.Results: VE of a mRNA booster dose was 62.6% (95% CI: 37.6%, 77.6%), compared with 2-dose primary mRNA vaccination. Additionally, HCP with a college degree (vs no degree), private insurance (vs government), and an income level $200K+ (vs < $50K) were more likely to have received the booster vaccine.Conclusions: The mRNA COVID-19 booster vaccine conferred approximately 63% protection against COVID-19 among Oregon HCP. These findings encourage remaining up-to-date with subsequent COVID-19 vaccines.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144939033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study sought to better characterize HCP attitudes toward cleaning and MDRO transmission, as well as describe cleaning practices for mobile equipment.Methods: Fifteen focus groups were conducted at 3 skilled nursing facilities (n ≥ 4 focus groups per site) with HCP likely to be tasked with cleaning mobile equipment (ie, nurses, certified nursing assistants, and environmental service workers). Focus groups were recorded and transcribed, reviewed for accuracy, and analyzed by 2 independent reviewers using thematic analysis.Results: Participants at all 3 sites described suboptimal cleaning practices of mobile equipment. Barriers to MDRO infection prevention and control practices included time pressure, knowledge gaps, and cost (material and staff).Conclusions: Many of these challenges can be addressed through role-specific education campaigns, substituting dedicated equipment (eg, vital signs carts) for mobile equipment where possible, and human factors-based interventions to support cleaning efforts within existing clinical workflow.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144938907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to evaluate the predictive value of inflammatory indices, Aggregate Index of Systemic Inflammation (AISI), Systemic Inflammatory Index (SII), and Systemic Inflammatory Response Index (SIRI), within 2 calendar days of central line insertion.Methods: We conducted a retrospective analysis of patients who underwent central line insertion. Indices were calculated with the parameters collected within 2 calendar days post-insertion. Logistic regression analysis was used to assess the predictive performance.Results: Among 234 patients, 39 were CLABSI-positive. We found all 3 indices significantly elevated in the CLABSI-positive group and logistic regression confirmed each index as an independent predictor of CLABSI. AISI demonstrated the strongest overall performance, with an optimal cutoff of 3,257.4 yielding the highest area under the receiver operating characteristic curve (AUROC = 0.75) and a sensitivity of 87.2%. These indices may serve as the effective early screening marker for CLABSI in this cohort.Conclusions: AISI, SII, and SIRI offer promising, accessible and low-cost early warning tools for CLABSI prediction with AISI emerging as the most reliable marker within 2 calendar days of central line insertion, enabling timely decisions.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144938939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BSI can be inaccurately attributed due to BC contamination or bacterial translocation. Reporting BCs after patient death (PD) can be inaccurate and potentially increase BSI incidence.Methods: The study was performed in two phases, a retrospective review of positive BCs that resulted after PD and a prospective phase of discontinuing BC after PD. A cost-benefit analysis was conducted of the program considering the cost of HAIs.Results: Retrospectively, there were 4,868 positive BC (10%) and 407 (8%) were finalized after PD. The BCs that resulted after PD and were identified as HAI included 8 CLABSI (Central Line Associated Blood Stream Infections), 11 primary and 25 secondary BSIs. During the prospective phase, the infection preventionists reviewed 795 patients and identified 285 with pending BC at the time of PD. 90.5% of these cultures were cancelled, reducing the number of potential HAI events related to BCs after PD to seven.Conclusions: HAI rates could be falsely increased as NHSN (National Healthcare Safety Network) definitions do not address positive BC after PD. Implementing a stewardship protocol to discontinue BCs after PD is appropriate clinical practice and likely cost beneficial.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144938975","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Malnutrition has been associated with adverse outcomes, including higher rates of surgical site infections (SSIs). Food insecurity, affecting approximately 9% of U.S. adults aged 65 and older, may contribute to malnutrition and influence postoperative recovery. This systematic review examines the relationship between food security, nutritional status, and SSIs in patients undergoing TJA.Methods: A systematic search of PubMed and CINAHL was conducted between January and October 2024 for studies published before December 2023, following PRISMA guidelines. Eligible studies assessed the impact of food access and/or nutritional status on SSI incidence among TJA patients. Data on study characteristics, nutritional indicators, SSI rates, and postoperative outcomes were extracted and analyzed.Results: Of 2,766 articles identified, 20 met inclusion criteria. Malnutrition, particularly low serum albumin, was significantly associated with increased SSIs, longer hospital stays, higher complication rates, and increased readmissions. However, no studies directly evaluated the impact of food insecurity on SSIs.Conclusions: These findings support the implementation of preoperative nutritional and food security screening to identify at-risk patients and guide interventions that may improve postoperative outcomes.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144939042","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In response, the hospital sought a targeted intervention for MRSA prevention within 2 intensive care units using an alcohol based nasal antiseptic.Methods: In August 2021, Infection Prevention and Control (IPC) partnered with Nursing and the alcohol-based nasal antiseptic product vendor to implement the product in the 2 units. Nasal antiseptic was administered twice daily. To measure process adherence, a report was created within the electronic medical record to track compliance. Patient tracking and communication of data reports to nurse leadership by IPC began shortly afterward.Results: MRSA standardized infection ratios (SIR) declined with an SIR of 1.18 in 2021 to an SIR of 0.90 in 2023. The total number of MRSA cases decreased from 2021 to 2022 with 4 cases and 1 case, respectively.Discussion: Barriers were identified, including personnel permitted to administer alcohol-based antiseptic, product location, and administration documentation. As these were addressed, compliance in administration began to increase. Manually tracking compliance was later replaced with an automated report for sustainability purposes. Options available to analyze the data were limited due to lack of control data.Conclusion: Implementation of universal decolonization using twice daily alcohol based nasal antiseptic can be accomplished and assessed with the development of an electronic data tracking process.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":2.4,"publicationDate":"2025-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144938992","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
