These products, often not meeting any standards, raised concerns about their effectiveness in reducing the spread of respiratory viruses.Methods: This study quantified total outward leakage (TOL) of units from 9 face-worn product categories used by members of the general public. A benchtop system was devised to test 2 units from each category on 2 different-sized headforms with silicone elastomer skin. Each unit was donned 5 times per headform.Results: Both face-worn product category and headform size significantly affected TOL (P value < .05). The TOL of tested face-worn products varied from 10% to 58% depending on both model and headform size. Face-worn products donned on the medium headform had a higher mean TOL compared to those donned on the larger headform.Conclusions: Overall, single-layer cloth masks are the least effective measure for source control due to their highest TOL among the tested face-worn products. Three-layer disposable face masks may be a favorable option for source control among the public. A standard should be developed for face-worn product design and manufacturing to accommodate different facial sizes.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142339278","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}

Initially, neurological procedures were a common risk factor among cases, leading to sampling of related environmental settings. Cases with other medical procedures started to be reported. The pulsed-field gel electrophoresis results showed most R mannitolilytica isolates were indistinguishable, which expanded our investigation to all hospital areas. The outbreak source was traced to a specific lot of contaminated sodium chloride solution, which was recalled from all hospital units. The findings were reported to the Saudi Food and Drug Authority to communicate with the manufacturer and other health care organizations involved. No new cases of R mannitolilytica were identified thereafter.Conclusions: It is essential to regularly monitor the compliance of manufacturers and suppliers with regulations related to the safety of solutions administered in medical practice.

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).Conclusions: This novel approach allows facilities to staff their IPC program based on individual factors.

Effective hand hygiene (HH) is crucial for prevention, but achieving high compliance remains challenge. This study explores using machine learning to integrate an electronic HH auditing system with electronic health records to predict HAIs.Methods: A retrospective cohort study was conducted at a Brazilian hospital during 2017-2020. HH compliance was recorded electronically, and patient data were collected from electronic health records. The primary outcomes were HAIs per CDC/National Healthcare Safety Network surveillance definitions. Machine learning algorithms, balanced with Random Over Sampling Examples (ROSE), were utilized for predictive modeling, including generalized linear models (GLM); generalized additive models for location, scale, and shape (GAMLSS); random forest; support vector machine; and extreme gradient boosting (XGboost).Results: 125 of 6,253 patients (2%) developed HAIs and 920,489 HH opportunities (49.3% compliance) were analyzed. A direct correlation between HH compliance and HAIs was observed. The GLM algorithm with ROSE demonstrated superior performance, with 84.2% sensitivity, 82.9% specificity, and a 93% AUC.Conclusions: Integrating electronic HH auditing systems with electronic health records and using machine learning models can enhance infection control surveillance and predict patient outcomes. Further research is needed to validate these findings and integrate them into clinical practice.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-09-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142306962","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}

Of 780 residents observed, one third met EBP indications: MDRO colonization (21%), indwelling medical device (14%), and/or chronic wound (10%). The most noted facilitator to EBP implementation included HCP perception that EBP reduces MDRO transmission to other residents and staff.

We surveyed IPs covering ambulatory/procedural locations regarding clinical complexity indicators and estimated hours per week spent engaged in IP activities. The reported hours were used to calculate total IP hours per week and associated full-time equivalents (FTEs).Results: Half (118/237) of surveyed locations/services reported at least 1 complexity indicator, while nearly 9% (21/237) reported 3 or more complexity indicators. IPs spent 181.0 h/wk focused on ambulatory/procedural locations, equating to 4.5 FTEs.Discussion: Infection prevention and control leadership used these findings to successfully add 4 IP FTEs to the department. These FTEs will allow increased ambulatory/procedural IP support, improved regulatory readiness, and increased quality improvement initiatives.Conclusions: Assessing the complexity and scope of pediatric ambulatory/procedural locations can be a valuable tool for (1) advocating for overall IP staffing increases at a system level and (2) determining the distribution of IP time and resources in such locations.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142456031","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}

To improve vaccination coverage rates, some municipalities began to independently provide subsidization programs for the mumps vaccine. However, the changes in vaccination coverage and incidence of mumps before and after initiating the subsidization programs remain unknown.METHODSIn April 2018, a city in Japan started a subsidization program for the mumps vaccine for children aged 1-6 years. This study used data on vaccination records and healthcare claims from the city obtained between July 2016 and December 2019. We described changes in vaccination coverage, and the incidence of mumps infections before and after the start of the subsidization program.RESULTSThe mumps vaccination coverage rate among eligible children was 3.3% at the program's initiation; this increased by about 1.5% per month, reaching 38.4% 21 months after the initiation of the program. Among 308,976 individuals, 145 cases of mumps were identified; of these, 92 cases (0.27 cases per 1,000 person-years) occurred before, and 53 (0.15 cases per 1,000 person-years) occurred after the initiation of the subsidization program.CONCLUSIONWhile the mumps vaccination coverage rate increased after the initiation of the subsidization program, it did not reach the level required for eradication.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":null,"pages":null},"PeriodicalIF":4.9,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254193","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}
