RESUMEN

Background: It is generally accepted that shoes and floors are contaminated with pathogens including methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant enterococci (VRE), and Clostridium difficile, yet correlation to clinical infection is not well established. Because floors and shoes are low-touch surfaces, these are considered non-critical surfaces for cleaning and disinfection. The purpose of this review is to assess peer-reviewed literature inclusive of floors and shoe soles as contributors to the dissemination of infectious pathogens within healthcare settings. Methods: Using the Preferred Reporting Items for Systematic Reviews (PRISMA) methodology, PubMed and Medline were searched for articles assessing the presence of pathogens on or the transmission of pathogens between or from floors or shoe soles/shoe covers. Inclusion criteria are the human population within healthcare or controlled experimental settings after 1999 and available in English. Results: Four hundred eighteen articles were screened, and 18 articles documented recovery of bacterial and viral pathogens from both floors and shoes. Seventy-two percent (13/18) of these were published after 2015, showing increased consideration of the transfer of pathogens to high-touch surfaces from shoe soles or floors during patient care. Conclusions: There is evidence that floors and shoes in healthcare settings are contaminated with several different species of health-care-associated pathogens including MRSA, VRE, and Clostridium difficile.

RESUMEN

BACKGROUND: The U.S. Patient Protection and Affordable Care Act created the Hospital Readmissions Reduction Program (HRRP) and the Hospital-Acquired Condition Reduction Program (HACRP). Under these programs, hospitals face reimbursement reductions for having high rates of readmission and hospital-acquired conditions. This study investigated whether readmission following total joint arthroplasty (TJA) under the HRRP was associated with reimbursement penalties under the HACRP. METHODS: Hospital-level data on hospital-acquired conditions, readmissions, and financial penalties were obtained from Definitive Healthcare. Outcomes included receipt of an HACRP penalty and the associated losses in revenue in 2018. Logistic regression and linear regression models were used to determine whether the all-cause, 30-day readmission rate following TJA was associated with the receipt or magnitude of an HACRP penalty. RESULTS: Among 2,135 private, acute care hospitals, 477 (22.3%) received an HACRP penalty. After controlling for other patient and hospital characteristics, hospitals with a 30-day readmission rate of >3% after TJA had over twice the odds of receiving an HACRP penalty (odds ratio, 2.20; p = 0.043). In addition, hospitals with a readmission rate of >3% after TJA incurred $77,519 more in revenue losses due to HACRP penalties (p = 0.011). These effects were magnified in higher-volume hospitals. CONCLUSIONS: Acute care hospitals in the United States with higher 30-day readmission rates following TJA are more likely to be penalized and to have greater revenue losses under the HACRP than hospitals with lower readmission rates after TJA. This strengthens the incentive to invest in the prevention of readmissions after TJA, for example, through greater efforts to reduce surgical site infections and other modifiable risk factors.

RESUMEN

Patients undergoing surgery may be at risk for infection from airborne particles such as dust, skin scales, respiratory aerosols, and hair fibers emanating from multiple sources in the OR, including personnel, heater-cooler devices, and surgical smoke. This risk is increased in surgical patients undergoing procedures involving implanted devices. Surgical personnel also are at risk from exposure to surgical smoke, which can contain viable viral particles including human papillomavirus infection. Air quality in the OR is improved by engineering controls (eg, maintaining positive pressure). During the past decade, innovations in the field of adjunctive technology designed to improve OR air quality include using ultraviolet disinfection and mobile ultraviolet disinfection plus high-efficiency particulate air filtration. Some of these technologies additionally provide continuous monitoring of circulating air particle counts. Additional research regarding the benefits of adjunctive air-cleaning technology in the OR is warranted.

RESUMEN

Research is an integral component of the mission of the Association for Professionals in Infection Control and Epidemiology (APIC). In January 2010, APIC 's Board of Directors decided to update and clarify the Association's approach to research. The purpose of this paper is to briefly review the history of APIC's role in research and to report on the recent vision and direction developed by a research task force regarding appropriate roles and contributions for APIC and its members in regards to research. APIC and its membership play critical roles in the research process, especially in terms of setting the research agenda so that research resources can be directed to important areas. Additionally, dissemination and implementation are areas in which APIC members can utilize their unique talents to ensure that patients receive the most up-to-date and evidence-based infection prevention practices possible.

RESUMEN

Hospital-acquired infections (HAIs) take a significant toll not only on patients, but also on a hospital's bottom line. By taking a zero tolerance approach to HAIs, hospital leaders can improve patient safety and financial performance. Eliminating HAIs requires clear goals, a committed leadership, access to resources, a best-practice mindset, effective people management, and ongoing vigilance.
