Background: Hospital-acquired Clostridioides difficile infection (HA-CDI) is a major infection control challenge. Using whole-genome sequencing, <40% of HA-CDI cases have been estimated to have been acquired from other inpatient cases. Huge regional variations have been described depending on the prevalence of epidemic ribotypes. We hypothesized that, according to the geographical area, variations in HA-CDI rates between hospitals could be attributable either to differences in infection control policies or to antimicrobial consumption. Objectives: To assess the association of HA-MRSA rates (a surrogate marker of infection control policies) and antimicrobial consumption with HA-CDI incidence from 2011 to 2018 in hospitals reporting at the VINCat-program (Infection Control and Antimicrobial Stewardship Catalan Program). Methods: Data on 45 hospitals in Catalonia (with 70.5% of all adult acute-care hospital beds) reporting antimicrobial consumption, HA-MRSA, and HA-CDI new cases to the VINCat-program since 2011 to 2018 were analyzed. To report antimicrobial consumption, the Anatomical Therapeutic Chemical Classification (ATC) defined daily dose (DDD) index 2018 was used. Participating hospitals were classified into 3 groups according to size: group 1 (>500 beds), 9 hospitals; group 2 (500–200 beds), 15 hospitals; and group 3 (<200 beds), 21 hospitals. The number of hospitalization days recorded at the participating hospitals increased from 2,828,101 in 2011 to 3,201,680 in 2018. To analyze the association between HA-MRSA rate, antimicrobial consumption and the rate of CDI-HA, a Poisson regression model was used. HA-CDI annually new cases have been defined as a dependent variable, the stays as an offset of the model and the HA-MRSA rates and antimicrobial consumption (measured in DDD) as independent factors. The exponents of model coefficients are equal to incidence rate ratios (IRR). Results: The regression model showed an association of with antimicrobial consumption with HA-CDI (IRR,1.05; 95% CI, 1.03–1.07; P < .001) and a lack of association with HA-MRSA (IRR, 0.83; 95% CI, 0.46–1.48; P = .52). Conclusions: The HA-CDI incidence rate grew annually by 5% for an increase of 1 DDD in annual antibiotic consumption. No association HA-MRSA rates was detected, suggesting that antimicrobial stewardship programs are urgently needed to improve the control of HA-CDI in Catalonia, a geographical area with a low prevalence of epidemic ribotypes.Funding: NoneDisclosures: Juan Pablo Horcajada reports consulting fees from MSD, Pfizer, and Menarini and speaker honoraria from MSD, Pfizer, and Zambon.

OBJECTIVETo offer antimicrobial stewardship to a long-term acute care hospital using telemedicine.METHODSWe conducted an uninterrupted time-series analysis to measure the impact of antimicrobial stewardship on hospital-acquired Clostridium difficile infection (CDI) rates and antimicrobial use. Simple linear regression was used to analyze changes in antimicrobial use; Poisson regression was used to estimate the incidence rate ratio in CDI rates. The preimplementation period was April 1, 2010–March 31, 2011; the postimplementation period was April 1, 2011–March 31, 2014.RESULTSDuring the preimplementation period, total antimicrobial usage was 266 defined daily doses (DDD)/1,000 patient-days (PD); it rose 4.54 (95% CI, −0.19 to 9.28) per month then significantly decreased from preimplementation to postimplementation (−6.58 DDD/1,000 PD [95% CI, −11.48 to −1.67]; P=.01). The same trend was observed for antibiotics against methicillin-resistant Staphylococcus aureus (−2.97 DDD/1,000 PD per month [95% CI, −5.65 to −0.30]; P=.03). There was a decrease in usage of anti-CDI antibiotics by 50.4 DDD/1,000 PD per month (95% CI, −71.4 to −29.2; P<.001) at program implementation that was maintained afterwards. Anti-Pseudomonas antibiotics increased after implementation (30.6 DDD/1,000 PD per month [95% CI, 4.9–56.3]; P=.02) but with ongoing education this trend reversed. Intervention was associated with a decrease in hospital-acquired CDI (incidence rate ratio, 0.57 [95% CI, 0.35–0.92]; P=.02).CONCLUSIONAntimicrobial stewardship using an electronic medical record via remote access led to a significant decrease in antibacterial usage and a decrease in CDI rates.Infect.

Background/Aims Hospital-acquired infections pose a risk to the wellbeing of both patients and staff. They are largely preventable, particularly if hospital staff have adequate knowledge of and adherence to infection control policies. This study aimed to assess the knowledge, awareness and practice of hospital-acquired infection control measures among hospital staff. Methods A cross-sectional study was conducted among 71 staff members in a tertiary healthcare facility in Karnataka, India. The researchers distributed a questionnaire containing 33 questions regarding knowledge of hospital-acquired infections, awareness of infection control policies and adherence to control practices. The results were analysed using the Statistical Package for the Social Sciences, version 16.0 and a Kruskal–Wallis test. Results Respondents' mean percentage score on the knowledge of hospital-acquired infections section was 72%. Their mean percentage scores on the awareness and practice of infection prevention measures sections were 82% and 77% respectively. Doctors and those with more years of experience typically scored higher. Conclusion The respondents had an acceptable level of knowledge, awareness and adherence to infection control practices. However, continued training is essential in the prevention of hospital-acquired infections. The majority of the respondents stated that they were willing to undertake training in this area, and this opportunity should be provided in order to improve infection control quality.

The COVID-19 pandemic has changed the way we practice medicine and lead our lives. In addition to pulmonary symptoms; COVID-19 as a syndrome has multisystemic involvement including frequent gastrointestinal symptoms such as diarrhea. Due to microbiome alterations with COVID-19 and frequent antibiotic exposure, COVID-19 can be complicated by Clostridioides difficile infection. Co-infection with these two can be associated with a high risk of complications. Infection control measures in hospitals is enhanced due to the COVID-19 pandemic which in turn appears to reduce the incidence of hospital-acquired infections such as C. difficile infection. Another implication of COVID-19 and its potential transmissibility by stool is microbiome-based therapies. Potential stool donors should be screened COVID-19 symptoms and be tested for COVID-19.

The Impact

During the COVID-19 pandemic, the implementation of antimicrobial stewardship strategies has been recommended. This study aimed to assess the impact of the COVID-19 pandemic in a tertiary care Spanish hospital with an active ongoing antimicrobial stewardship programme (ASP). For a 20-week period, we weekly assessed antimicrobial consumption, incidence density, and crude death rate per 1000 occupied bed days of candidemia and multidrug-resistant (MDR) bacterial bloodstream infections (BSI). We conducted a segmented regression analysis of time series. Antimicrobial consumption increased +3.5% per week (p = 0.016) for six weeks after the national lockdown, followed by a sustained weekly reduction of −6.4% (p = 0.001). The global trend for the whole period was stable. The frequency of empirical treatment of patients with COVID-19 was 33.7%. No change in the global trend of incidence of hospital-acquired candidemia and MDR bacterial BSI was observed (+0.5% weekly; p = 0.816), nor differences in 14 and 30-day crude death rates (p = 0.653 and p = 0.732, respectively). Our work provides quantitative data about the pandemic effect on antimicrobial consumption and clinical outcomes in a centre with an active ongoing institutional and education-based ASP. However, assessing the long-term impact of the COVID-19 pandemic on antimicrobial resistance is required.

Abstract Objective: To estimate the impact of California’s antimicrobial stewardship program (ASP) mandate on methicillin-resistant Staphylococcus aureus (MRSA) and Clostridioides difficile infection (CDI) rates in acute-care hospitals. Population: Centers for Medicare and Medicaid Services (CMS)–certified acute-care hospitals in the United States. Data Sources: 2013–2017 data from the CMS Hospital Compare, Provider of Service File and Medicare Cost Reports. Methods: Difference-in-difference model with hospital fixed effects to compare California with all other states before and after the ASP mandate. We considered were standardized infection ratios (SIRs) for MRSA and CDI as the outcomes. We analyzed the following time-variant covariates: medical school affiliation, bed count, quality accreditation, number of changes in ownership, compliance with CMS requirements, % intensive care unit beds, average length of stay, patient safety index, and 30-day readmission rate. Results: In 2013, California hospitals had an average MRSA SIR of 0.79 versus 0.94 in other states, and an average CDI SIR of 1.01 versus 0.77 in other states. California hospitals had increases (P < .05) of 23%, 30%, and 20% in their MRSA SIRs in 2015, 2016, and 2017, respectively. California hospitals were associated with a 20% (P < .001) decrease in the CDI SIR only in 2017. Conclusions: The mandate was associated with a decrease in CDI SIR and an increase in MRSA SIR.

Abstract Background Microbial bio-burden on high-touch surfaces in patient rooms may lead to acquisition of health care–associated infections in acute care hospitals. This study examined the effect of a novel copper-impregnated solid material (16%–20% copper oxide in a polymer-based resin) on bacterial contamination on high-touch surfaces in patient rooms in an acute care hospital. Methods Five high-touch surfaces were sampled for aerobic bacterial colonies (ABCs) 3 times per day over a 3-day period in 16 rooms with copper installed and 16 rooms with standard noncopper laminate installed on high-touch surfaces. A Bayesian multilevel negative binomial regression model was used to compare ABC plate counts from copper-impregnated surfaces with standard hospital laminate surfaces. Results The mean and median (interquartile range [IQR]) ABC counts from copper-impregnated surfaces were 25.5 and 11 (4–27), and for standard hospital laminate surfaces they were 60.5 and 29 (10–74.3). The negative binomial regression model–estimated incidence rate for ABC counts on plates taken from copper-impregnated surfaces was 0.40 (0.21–0.70) times the incidence rate of ABC counts on plates taken from standard hospital laminate surfaces. Conclusions Copper-impregnated solid surfaces may reduce the level of microbial contamination on high-touch surfaces in patient rooms in the acute care environment, as our study demonstrated a decline in microbial bio-burden on samples taken from copper-impregnated compared with standard hospital laminate high-touch surfaces.

Abstract Background The excessive and inappropriate use of antibiotics is universal across all healthcare facilities. In Qatar there has been a substantial increase in antimicrobial consumption coupled with a significant rise in antimicrobial resistance (AMR). Antimicrobial stewardship programmes (ASPs) have become a standard intervention for effective optimization of antimicrobial prescribing. Methods A before–after study was conducted in Hamad General Hospital (603 bed acute care hospital): 1 year before implementation of a comprehensive ASP compared with the following 2 years. The ASP included a hospital-wide pre-authorization requirement by infectious diseases physicians for all broad-spectrum antibiotics. Prevalence of MDR Pseudomonas aeruginosa was compared with antimicrobial consumption, calculated as DDD per 1000 patient-days (DDD/1000 PD). Susceptibility was determined using broth microdilution, as per CLSI guidelines. Antibiotic use was restricted through the ASP, as defined in the hospital’s antibiotic policy. Results A total of 6501 clinical isolates of P. aeruginosa were collected prospectively over 3 years (2014–17). Susceptibility to certain antimicrobials improved after the ASP was implemented in August 2015. The prevalence of MDR P. aeruginosa showed a sustained decrease from 2014 (9%) to 2017 (5.46%) (P = 0.019). There was a significant 23.9% reduction in studied antimicrobial consumption following ASP implementation (P = 0.008). The yearly consumption of meropenem significantly decreased from 47.32 to 31.90 DDD/1000 PD (P = 0.012), piperacillin/tazobactam from 45.35 to 32.67 DDD/1000 PD (P &lt; 0.001) and ciprofloxacin from 9.71 to 5.63 DDD/1000 PD (P = 0.015) (from 2014 to 2017). Conclusions The successful implementation of the ASP led to a significant reduction in rates of MDR P. aeruginosa, pointing towards the efficacy of the ASP in reducing AMR.

Abstract Background Many patients are avoiding essential care for fear of contracting Covid-19 in healthcare settings. However, the incidence of nosocomial Covid-19 infection in U.S. acute care hospitals is unknown. Methods We conducted an observational study of all patients admitted to Brigham and Women’s Hospital in Boston, Massachusetts between March 7 (when the first Covid-19 patient was admitted) and May 30, 2020. During this period, a comprehensive infection control program was implemented including dedicated Covid-19 units with airborne infection isolation rooms, personal protective equipment (PPE) in accordance with CDC recommendations, PPE donning and doffing monitors, universal masking, restriction of visitors, and liberal RT-PCR testing of symptomatic and asymptomatic patients. We reviewed the medical records of all patients who tested positive for SARS-CoV-2 by RT-PCR on hospital day 3 or later or within 14 days of hospital discharge to determine whether infection was community or hospital-acquired based on timing of RT-PCR tests, clinical course, and exposures. Results Over the 12-week period, 9,149 patients were admitted, in whom 7,394 SARS-CoV-2 RT-PCR tests were performed and 697 Covid-19 cases were confirmed, translating into a total 8,656 days of Covid-19-related care (Figure). The inpatient Covid-19 census peaked at 171 on April 21. Twelve of the 697 Covid-19 patients (1.7%) were first diagnosed by RT-PCR on hospital day 3 or later (median 4 days, range 3–15 days). Of these, only one was deemed hospital-acquired and was most likely acquired from his pre-symptomatic spouse who was visiting daily and diagnosed with Covid-19 before visitor restrictions were implemented. Amongst 8,370 non-Covid-19 patients discharged through June 17, 11 (0.1%) subsequently tested positive within 14 days (median time to diagnosis 6 days, range 1–14). Only one was deemed likely to have been hospital-acquired, albeit with no known exposures. Figure. Timeline of implementation of major infection control policies and cumulative number of hospitalized COVID-19 cases (total and hospital-onset) Conclusion Nosocomial Covid-19 infection was exceedingly rare during the height of the pandemic in a hospital with rigorous infection control measures. Our findings may inform practices in other institutions and provide reassurance to patients regarding the safety of receiving care in acute care hospitals.
