Performance was assessed under dynamic (3.6 L/min flow, 6h/day) and static (8-day stagnation) conditions.Results: Under dynamic conditions, the BPSH filter consistently maintained effluent bacterial concentrations ≤10 CFU/100 mL for all three organisms throughout the 64-day study. In contrast, the PES and PP filters showed progressive deterioration in performance. Under static conditions, BPSH maintained <1 CFU/100 mL for all organisms over 7 days, whereas PES and PP exceeded the limit from day 2 for P aeruginosa and E coli, and from day 6 for S aureus.Discussion: The sustained efficacy of BPSH under both dynamic and static conditions is attributed to the continuous release of active bromine. This release kills retained bacteria and offers a significant advantage over conventional physical filters.Conclusion: BPSH provides consistent, high bacterial removal under both conditions, ideal for clinical settings with intermittent downtime.","PeriodicalId":7621,"journal":{"name":"American journal of infection control","volume":" ","pages":""},"PeriodicalIF":2.6,"publicationDate":"2026-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148910608","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}

Multivariate linear regression examined associations between home environment and sociodemographic, clinical, and community factors.Results: On average, at least 1 household hazard was observed; poor lighting and clutter were the most common, followed by infestation. Homes were predominantly assessed as mostly clean but exhibited moderate clutter. Older age, being Hispanic, and more favorable IPC attitudes were associated with greater cleanliness. Difficulty paying medical bills was associated with higher clutter scores. High neighborhood deprivation was associated with lower clutter scores.Discussion: Although homes were mostly clean, clutter and hazards were common and may impede IPC practices.

We evaluated a pharmacist-led bundled program in a county-level tertiary referral hospital.Methods: We conducted a retrospective interrupted time-series study using monthly hospital-level data from January 2019 through December 2024. The program combined multidisciplinary governance, departmental accountability, tiered antimicrobial authorization, computerized pre-prescription review, and ward-based pharmacist stewardship. The primary outcome was antimicrobial use density (AUD), expressed as defined daily doses per 100 patient-days; prescribing appropriateness was an exploratory process outcome.Results: Annual hospital-wide AUD decreased from 55.93 in 2019 to 31.10 in 2024. Monthly AUD was already decreasing before implementation (-0.90 per month; 95% CI, -1.47 to -0.32).

Patients were excluded for death within 48 hours, neutropenia, receipt of antibiotics for an active infection, or urologic procedure with mucosal involvement. Two electronic interventions were implemented 1 year apart: a best practice advisory (BPA) prompting appropriate urine culture ordering, followed by a microbiology nudge at the time of urine culture results to encourage reassessment of therapy. Patients were categorized into pre-BPA, BPA, and BPA plus nudge (BPAN) cohorts. The primary outcome was antibiotic treatment for more than 24 hours.Results: A total of 903 patients were included (pre-BPA n = 572, BPA n = 112, BPAN n = 219).

Studies published between January 2013 to January 2026 were included.Results: Of 1,112 studies identified, 33 met inclusion criteria. Studies were categorized by outcome with 9 evaluating UTI interventions and measuring UTI rates, 10 measuring diagnostic accuracy and 19 reporting antimicrobial prescribing and several reporting multiple outcomes.Discussion: Multifaceted UTI management programs including antimicrobial stewardship and a combination of staff education, guidelines, decision-support tools and use of change champions effectively reduced UTI rates. Diagnostic inconsistencies exist when applying McGeer surveillance criteria, Loeb's minimum criteria, and specific organizational criteria potentially resulting in inappropriate antimicrobial prescribing.Conclusions: A standardized, validated UTI definition is needed to improve diagnostic accuracy and support antimicrobial stewardship for older populations.
