Despite contact precautions (CP) being recommended as an infection prevention measure, little is known about the burden of CP on health care workers (HCWs).Methods: An online survey was conducted between May 2021 and August 2022 at baseline (BP) and intervention period (IP) of a multicenter trial discontinuing CP for patients colonized with third-generation cephalosporin resistant gram-negative bacteria in which 38 ICUs participated.Results: 147 HCWs from 33 ICUs (BP), 154 HCWs from 38 ICUs (IP) responded to the survey. At BP, most burdensome were: donning personal protective equipment (PPE) in case of emergency (84.0%), need of additional time (73.5%), elevated time management requirements to complete all daily tasks (68.7%), transport to diagnostic areas (65.2%). A significant reduction during IP was shown for: transport to diagnostic areas (p = .010), elevated time management requirements to complete all daily tasks (p = .004), need of additional time (p = .020), donning and doffing PPE (p = .014), increased hand and surface disinfection (p = .035) and anxiety (p = .031).Conclusions: Removing CP may be associated with considerable relief in burden for HCWs. However, removing CP must be guided by defined evidence since infection prevention control must be ensured.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143476149","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}

Output dosing was evaluated for consistency to comply with the Leapfrog 2022 guidance requirement of ≥1.0mL per ABHR dispense.Methods: Fifteen dispensers and 32 distinct refills were tested, with >10,000 dispenses analyzed for 5 different dispensing systems. Automated testing used computer programming and mechatronics to activate the dispensers and capture output weights at predetermined delay patterns. Low, medium, and high usage patterns per day were set with dispense delay patterns. In another laboratory, dispensers were activated manually for measurements; 50 doses were collected and weighed within an hour for each refill.Results: Three of the dispenser systems had mean output >1.0 mL, and 2 were <1.0 mL. Two dispensers have significantly greater variability, which is driven by the foam pump design.Conclusions: It was discovered that usage/testing patterns impact dosing performance. The dispenser design and engineering cause significant differences in volume dispensed and consistency across dispenses. Using sufficient ABHR to cover hands completely and keeping hands wet long enough to significantly reduce pathogens is an important requirement. Facilities should assess ABHR dispenser outputs and consider consistent dosing as an essential performance criterion for effective hand hygiene policies and practices.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143456836","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}

A total of 208 out of 450 health care workers completed a Theoretical Domain Framework-based survey, and 16 patients and 12 health workers were interviewed. Survey results were compared by professional category; interviews were analyzed using Critical Discourse Analysis.Results: Professionals with higher education scored higher across most domains. In the \"Optimism\" domain, these professionals scored ≥6.0, while others scored ≤5.0. Similar patterns were observed in the domains \"Knowledge\" (≥6.0 vs ≤5.5), \"Social/professional role and identity\" (≥6.36 vs ≤5.79), and \"Intentions\" (≥6.0 vs ≤5.0). Qualitative data highlighted breaks in the continuity of care and gaps in patient knowledge about antimicrobial use. Key barriers included disparities in training, physician-centered decision-making, and patient knowledge gaps. Enablers included health care workers' willingness to learn and home caregivers' understanding of patient conditions.Conclusions: The implementation of the antimicrobial stewardship program depends on addressing training disparities and leveraging health care workers' willingness to learn.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143432024","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}

Three reviewers independently validated qualitative analysis of findings. Virtual meetings were leveraged to discuss findings and identify themes.Results: 100% (9/9) of respondents changed COVID-19-associated isolation discontinuation guidance at least once. All (9/9) included patient immune status as criterion. All (9/9) required clearance testing at some point in the pandemic, 6 of 9 (66%) continued to require clearance testing at the time of the survey. Only 1 of 9 (11%) allowed antigen testing to meet criteria. Seven isolation titles were noted across 9 institutions, despite near agreement on measures employed.Discussion: Variability existed in COVID-19 management among study participants, despite serving similar populations, which may stem from limited data supporting understanding of viral transmissibility in immunocompromised hosts.Conclusions: Guideline development for immunocompromised hosts, potential drivers for viral evolution, can lack clarity for consistent management of the population. Engaging subject matters in specialty populations with future guideline development will improve infection prevention in health care settings.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143432023","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}

References for environmental service workers appeared more frequently in nursing home regulations (22 states) than in assisted living regulations (6 states). Infection control training was required more often in nursing homes (32 states) than in assisted living facilities (27 states). Gloves were the most common personal protective equipment cited, addressed in 14 state nursing home regulations and 13 state-level assisted living regulations. Only 7 state nursing home regulations and 2 assisted living regulations addressed carpet, with only 6 addressing high-touch items.Conclusions: State regulations inadequately address environmental service workers, staff training, carpets, and high-touch items.

Infections have been linked to surgical instruments with retained tissue and foreign debris, as the presence of blood or soil interferes with sterilization effectiveness. This study aimed to determine the prevalence of visible soil or debris inside instruments and evaluate the impact of recleaning efforts.Methods: Borescopes were used to inspect lumens of instruments used for orthopedic, neurologic, or ear-nose-throat procedures. Whenever visible soil or debris was observed, the instrument was recleaned up to 3 times and reinspected to assess the impact of additional cleaning.Results: Researchers performed 117 inspections (40 unique instruments, 77 reinspections). All instruments had complex lumens that impede access by brushes. Debris and discoloration or residues were observed inside 100% of instruments, with rusty patches in 95%. Some soil was removed by recleaning, but visible soil remained in most lumens and fragments of lint or brush bristles were visible upon repeat inspection.Conclusions: Cleaning in accordance with the manufacturer's instructions was not effective for lumened surgical instruments.

Previously reported bacteremia definitions were applied to determine the variability in rates by definition.Results: In 68 patients who received ECMO during the study period, 424 blood culture sets were obtained, of which 20 (4%) yielded CoNS in 13 (19%) patients. Only 5 (38%) patients had repeat isolation. Clinical variables, such as fever and leukocytosis, did not predict repeat positivity. Rates of CoNS varied from 0 to 15 infections per 1,000 ECMO days depending on the definition utilized.Conclusions: CoNS were frequently isolated in blood cultures from patients receiving ECMO. Despite the concern for biofilm formation, most CoNS were only isolated in a single culture. With the limited utility of clinical markers and frequent false positives, clinicians should order repeat blood cultures on those with CoNS isolated from blood cultures. We propose a standardized definition for CoNS bacteremia, which entails isolations of CoNS from 2 subsequent blood cultures.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143412763","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}
