Abstract
The abuse of tetracycline can lead to its residue in animal derived foods, posing many potential hazards to human health. Therefore, rapid and accurate detection of tetracycline is an important means to ensure food safety. Nitrogen doped and phosphorus doped silicon quantum dots (N-SiQDs, P-SiQDs) with remarkable optical stability were fabricated via a one-pot hydrothermal procedure in this study. Upon the excitation at 346 nm, N-SiQDs and P-SiQDs emitted fluorescence at 431 nm and 505 nm, respectively. Two SiQDs had the potential to serve as a probe for detecting low concentrations of tetracycline (TC), employing a mechanism of the static quenching effect. The calibration curves of N-SiQDs and P-SiQDs were linear within the range of 0-0.8 μM and 0-0.4 μM, the limits of detection were low as 5.35 × 10-4 μmol/L and 6.90 × 10-3 μmol/L, respectively. This method could be used successfully to detect TC in honey samples. Moreover, the remarkable antibacterial efficacy of two SiQDs could be attributed to the generation of a large number of intracellular reactive oxygen species. The SEM images showed that the structure of bacterial cell was disrupted and the surface became irregular when treated with both SiQDs. These properties enabled potential usage of SiQDs as excellent antibacterial material for different biomedical applications.

Abstract
BACKGROUND Long-term care facilities (LTCFs) present specific challenges for the implementation of antimicrobial stewardship (AMS) programmes. A growing body of literature is dedicated to AMS in LTCFs. OBJECTIVES We aimed to summarize barriers to the implementation of full AMS programmes, i.e. a set of clinical practices, accompanied by recommended change strategies. METHODS A scoping review was conducted through Ovid-MEDLINE, CINAHL, Embase and Cochrane Central. Studies addressing barriers to the implementation of full AMS programmes in LTCFs were included. Implementation barriers described in qualitative studies were identified and coded, and main themes were identified using a grounded theory approach. RESULTS The electronic search revealed 3904 citations overall. Of these, 57 met the inclusion criteria. All selected studies were published after 2012, and the number of references per year progressively increased, reaching a peak in 2020. Thematic analysis of 13 qualitative studies identified three main themes: (A) LTCF organizational culture, comprising (A1) interprofessional tensions, (A2) education provided in silos, (A3) lack of motivation and (A4) resistance to change; (B) resources, comprising (B1) workload and staffing levels, (B2) diagnostics, (B3) information technology resources and (B4) funding; and (C) availability of and access to knowledge and skills, including (C1) surveillance data, (C2) infectious disease/AMS expertise and (C3) data analysis skills. CONCLUSIONS Addressing inappropriate antibiotic prescribing in LTCFs through AMS programmes is an area of growing interest. Hopefully, this review could be helpful for intervention developers and implementers who want to build on the most recent evidence from the literature.

Abstract
The misuse of antibiotics and antimycotics accelerates the emergence of antimicrobial resistance, prompting the need for novel strategies to combat this global issue. Metallic nanoparticles have emerged as effective tools for combating various resistant microbes. Numerous studies have highlighted their potential in addressing antibiotic-resistant fungi and bacterial strains. Understanding the mechanisms of action of these nanoparticles, including iron-oxide, gold, zinc oxide, and silver is a central focus of research within the life science community. Various hypotheses have been proposed regarding how nanoparticles exert their effects. Some suggest direct targeting of microbial cell membranes, while others emphasize the release of ions from nanoparticles. The most compelling proposed antimicrobial mechanism of nanoparticles involves oxidative damage caused by nanoparticles-generated reactive oxygen species. This review aims to consolidate knowledge, discuss the properties and mechanisms of action of metallic nanoparticles, and underscore their potential as alternatives to enhance the efficacy of existing medications against infections caused by antimicrobial-resistant pathogens.

Abstract
OBJECTIVE In this study, we compared the proportion of antibiotic resistance between patients who visited the emergency department (ED) with urinary tract infection (UTI) from long-term care hospitals (LTCH), which is a type of long-term care facilities (LTCF) and the community. We assessed the resulting difference in prognosis. METHOD Older adults who visited the ED between January and December 2019 and were diagnosed with UTI were divided into community residents and LTCH residents. We investigated the antibiotics sensitivity rates, end of therapy (EOT), and the patient's outcomes were evaluated. RESULTS The antibiotic resistance rate was higher in LTCH residents. LTCH residents had a higher in hospital mortality rate compared to community residents. EOT was found to be longer, and admission rate and in-hospital mortality rate were also higher in LTCH residents. CONCLUSION LTCF residents had a higher rate of antibiotic resistance and a poor prognosis.

Abstract
Incontinence is a common health issue that affects hundreds of millions of people across the world. The solution is often to manage the condition with different kinds of single-use continence technologies, such as incontinence pads and other absorbent hygiene products (AHPs). Throughout their life cycle, these fossil-based products form a remarkable yet inadequately addressed ecological burden in society, contributing to global warming and other environmental degradation. The products are a necessity for their users' wellbeing. When looking for sustainability transitions in this field, focus on individual consumer-choice is thus inadequate - and unfair to the users. The industry is already seeking to decrease its carbon footprint. Yet, to tackle the environmental impact of single-use continence products, also societies and health systems at large must start taking continence seriously. Arguing that continence-aware societies are more sustainable societies, we devise in this article a society-wide working definition for holistically sustainable continence care. Involving dimensions of social, ecological and economic sustainability, the concept draws attention to the wide range of technologies, infrastructures and care practices that emerge around populations' continence needs. Holistically sustainable continence care is thus not only about AHPs. However, in this article, we examine holistically sustainable continence care through the case of AHPs. We review what is known about the environmental impact AHPs, discuss the impact of care practices on aggregate material usage, the future of biobased and degradable incontinence pads, as well as questions of waste management and circular economy. The case of AHPs shows how holistically sustainable continence care is a wider question than technological product development. In the end of the article, we envision an ecosystem where technologies, infrastructures and practices of holistically sustainable continence care can flourish, beyond the focus on singular technologies.

Abstract
Infections are important factors contributing to the morbidity and mortality among elderly patients. High rates of consumption of antimicrobial agents by the elderly may result in increased risk of toxic reactions, deteriorating functions of various organs and systems and leading to the prolongation of hospital stay, admission to the intensive care unit, disability, and lethal outcome. Both safety and efficacy of antibiotics are determined by the values of their plasma concentrations, widely affected by physiologic and pathologic age-related changes specific for the elderly population. Drug absorption, distribution, metabolism, and excretion are altered in different extents depending on functional and morphological changes in the cardiovascular system, gastrointestinal tract, liver, and kidneys. Water and fat content, skeletal muscle mass, nutritional status, use of concomitant drugs are other determinants of pharmacokinetics changes observed in the elderly. The choice of a proper dosing regimen is essential to provide effective and safe antibiotic therapy in terms of attainment of certain pharmacodynamic targets. The objective of this review is to perform a structure of evidence on the age-related changes contributing to the alteration of pharmacokinetic parameters in the elderly.

Abstract
Objective To examine antibiotic use in long-term care residents at a VA skilled nursing facility. Design Quality improvement project. Setting Long-term care residents admitted to the Community Living Center of a Midwestern VA medical
center. Patients Inclusion criteria were long-term care residents admitted to the VA skilled nursing facility who were prescribed an oral (including via percutaneous endoscopic gastrostomy tube) antibiotic from January 1, 2018, to December 31, 2018. Residents were excluded
if they were admitted for hospice care, rehabilitation, or short-term skilled nursing. Residents were also excluded if they were on intravenous or topical antibiotics. Results Fifty-six unique antibiotic courses consisting of 13 different antibiotics were evaluated. Median
days of therapy per 1,000 resident days was 39.7 overall, for quarter 1 was 51, quarter 2 was 42, quarter 3 was 49.3, and quarter 4 was 17.5. Average antibiotic days of therapy was 7.6 days. Fluoroquinolones comprised 26.8% of the courses, followed by beta-lactamase inhibitors at 25%. Of the
56 courses, 85.7% were found to have appropriate dose/frequency, while 73.2% had appropriate duration. No reports of Clostridioides difficile infection were noted. Thirty-one antibiotic courses had cultures obtained, of which 29 did not deescalate therapy. Of these, 5 (17.2%) were indicated
for de-escalation. Conclusion Antibiotic use in this skilled nursing facility have opportunities for intervention, including reducing fluoroquinolone use, optimizing de-escalation, and shortening days of therapy. The implementation of an antimicrobial stewardship monitoring
program within the long-term care setting could assist in maximizing therapy while reducing antibiotic exposure.

Abstract
Objectives We conducted a prospective, randomized, unblinded superiority trial of the safety and efficacy of modified reporting of positive urine cultures to improve the appropriateness of treatment for asymptomatic bacteriuria (ASB) and urinary tract infection (UTI) in long-term care facilities (LTCFs). Methods Consecutive positive urine cultures collected from LTCF patients were randomized between standard (identification and susceptibility) or modified (without identification and susceptibility) laboratory reports. Exclusion criteria were current antibiotic treatment, neutropenia, or transfer to acute care. The diagnosis of UTI or ASB was made prospectively. Results One hundred and sixty-nine urine cultures were considered, 100 were randomized and included in ITT analysis, and 96 were included in PP analysis. Sixty-two out of 100 (62%) patients had ASB [41/62 (66%) treated] and 38/100 (38%) had UTI [35/38 (92%) treated]. The lab was called to report the identification and susceptibility in 31/51 (61%) modified reports. The rate of appropriate treatment was higher in the modified report arm: 31/51 (61%) versus 25/49 (51%) (+10%, P = 0.33). Untreated ASB was higher in the modified report arm: 13/32 (41%) versus 8/30 (27%) (+14%, P = 0.25). There were two deaths (one treated ASB, one untreated ASB) and 15 adverse events in the modified arm. There were no deaths (P = 0.16) and 11 adverse events (P = 0.43) in the standard arm. Three patients with untreated UTI survived. Conclusions Modified reporting of urine culture improved the appropriateness of treatment by reducing treatment of ASB, but not significantly. Many LTCF prescribers requested standard urine culture reports. Modified reporting may not be suitable for LTCF implementation.

Abstract
With increasing incidence of antimicrobial resistance, there is an urgent need for novel and effective antibacterials. Destiny Pharma plc have developed a series of porphyrin-based XF drugs, some with dual mechanisms of antibacterial action. An innate mechanism acts through binding to the outer bacterial membrane and a separate, light-activated, photodynamic (PD) mechanism, acts via the generation of reactive oxygen species. This study aimed to assess the innate and PD associated antibacterial activity of XF drugs against planktonic bacteria, their biofilms and combinational effects with conventional antibiotics. Minimum inhibitory concentrations (MICs) were determined for 3 XF drugs against 114 bacterial isolates. MICs for XF-73 and XF-70 were determined (± PD). DPD-207 was designed to not exhibit PD action due to its structure. XF-drugs (± PD) were further assessed for synergy with conventional antibiotics (using a checkerboard assay) and antibiofilm activity against susceptible strains. XF drugs were innately active against all tested Gram-positive isolates. PD action significantly increased bacterial susceptibility to XF-73 and XF-70 for all Gram-positive isolates. Generally, the XF drugs exhibited higher MICs against Gram-negative isolates, however PD significantly enhanced potency, particularly for XF-70. XF-73 and XF-70 exhibited synergy with ertapenem against a methicillin resistant Staphylococcus aureus (MRSA) strain (± PD) and XF-73 with polymyxin B (± PD) against Pseudomonas aeruginosa. No antagonism was seen between the XF drugs and any of the 5 antibiotics tested. The antibiofilm effect of XF drugs was also observed for all Staphylococcus isolates tested. Generally, PD did not enhance activity for other bacterial isolates tested with the exception of XF-73 against Acinetobacter baumannii biofilms. XF drugs exhibited significant antimicrobial activity against Gram-positive bacteria, with PD enhancement of bacterial susceptibility. Additionally, XF drugs displayed synergy with conventional antibiotics and demonstrated antibiofilm effects.

Abstract
Urinary tract infections (UTIs) are the most common infections among nursing home (NH) residents. Antibiotics are often misused when a UTI is suspected. Using sophisticated information technology (IT) could help in appropriate UTI prevention, diagnosis, and treatment. This repeated cross-sectional study explored relationships between IT maturity and UTI prevalence among long-stay NH residents. Data were from (1) four annual surveys 2013-2017 measuring IT maturity in a random sample of Medicare-certified NHs, (2) Minimum Data Set assessments for resident characteristics, and (3) Certification and Survey Provider Enhanced Reporting data for facility characteristics. In multivariate regressions using NH fixed effects, controlling for resident and NH characteristics, Administrative IT maturity in NHs was associated with decreased odds of UTI (AOR: 0.906, 95% CI: 0.843, 0.973). These results were robust in all sensitivity analyses. Using IT to relieve administrative burden may decrease UTIs.

Abstract
IMPORTANCE Antibiotic overuse in long-term care (LTC) is common, prompting calls for antibiotic stewardship programs (ASPs) designed for specific use in these settings. The optimal approach to establish robust, sustainable ASPs in LTC facilities is unknown. OBJECTIVES To determine if the Agency for Healthcare Research and Quality (AHRQ) Safety Program for Improving Antibiotic Use, an educational initiative to establish ASPs focusing on patient safety, is associated with reductions in antibiotic use in LTC settings. DESIGN, SETTING, AND PARTICIPANTS This quality improvement study including 439 LTC facilities in the US assessed antibiotic therapy data following a pragmatic quality-improvement program, which was implemented to assist facilities in establishing ASPs and with antibiotic decision-making. Training was conducted between December 2018 and November 2019. Data were analyzed from January 2019 to December 2019. INTERVENTIONS Fifteen webinars occurred over 12 months (December 2018 to November 2019), accompanied by additional tools, activities, posters, and pocket cards. All clinical staff were encouraged to participate. MAIN OUTCOMES AND MEASURES The primary outcome was antibiotic starts per 1000 resident-days. Secondary outcomes included days of antibiotic therapy (DOT) per 1000 resident-days, the number of urine cultures per 1000 resident-days, and Clostridioides difficile laboratory-identified events per 10 000 resident-days. All outcomes compared data from the baseline (January-February 2019) to the completion of the program (November-December 2019). Generalized linear mixed models with random intercepts at the site level assessed changes over time. RESULTS Of a total 523 eligible LTC facilities, 439 (83.9%) completed the safety program. The mean difference for antibiotic starts from baseline to study completion per 1000 resident-days was -0.41 (95% CI, -0.76 to -0.07; P = .02), with fluoroquinolones showing the greatest decrease at -0.21 starts per 1000 resident-days (95% CI, -0.35 to -0.08; P = .002). The mean difference for antibiotic DOT per 1000 resident-days was not significant (-3.05; 95% CI, -6.34 to 0.23; P = .07). Reductions in antibiotic starts and use were greater in facilities with greater program engagement (as measured by webinar attendance). While antibiotic starts and DOT in these facilities decreased by 1.12 per 1000 resident-days (95% CI, -1.75 to -0.49; P < .001) and 9.97 per 1000 resident-days (95% CI, -15.4 to -4.6; P < .001), respectively, no significant reductions occurred in low engagement facilities. Urine cultures per 1000 resident-days decreased by 0.38 (95% CI, -0.61 to -0.15; P = .001). There was no significant change in facility-onset C difficile laboratory-identified events. CONCLUSIONS AND RELEVANCE Participation in the AHRQ safety program was associated with the development of ASPs that actively engaged clinical staff in the decision-making processes around antibiotic prescriptions in participating LTC facilities. The reduction in antibiotic DOT and starts, which was more pronounced in more engaged facilities, indicates that implementation of this multifaceted program may support successful ASPs in LTC settings.

Barriers and facilitators to infection prevention and control in Dutch residential care facilities for people with intellectual and developmental disabilities: A theory-informed qualitative study. PLoS One 2021; 16:e0258701. [PMID: 34714846 PMCID: PMC8555856 DOI: 10.1371/journal.pone.0258701] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Accepted: 10/02/2021] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND Care institutions are recognised to be a high-risk setting for the emergence and spread of infections and antimicrobial-resistant organisms, which stresses the importance of infection prevention and control (IPC). Accurate implementation is crucial for optimal IPC practice. Despite the wide promotion of IPC and research thereof in the hospital and nursing home setting, similar efforts are lacking in disability care settings. Therefore, this study aimed to assess perceived barriers and facilitators to IPC among professionals working at residential care facilities (RCFs) for people with intellectual and developmental disabilities (IDD), as well as to identify professional-reported recommendations to improve IPC. METHODS This qualitative study involved semi-structured interviews (before COVID-19) with twelve professionals from five Dutch RCFs for people with IDD. An integrated theoretical approach was used to inform data collection and analysis. Thematic analysis using inductive and deductive approaches was conducted. This study followed the COnsolidated criteria for REporting Qualitative research (COREQ) guidelines. RESULTS Our findings revealed barriers and facilitators at the guideline, client, professional, professional interaction, professional client interaction, client interaction, organisational, community, and societal level. Six main themes covering multiple barriers and facilitators were identified: (1) guidelines' applicability to (work)setting; (2) professionals' cognitions and attitude towards IPC (related to educational background); (3) organisational support and priority; (4) educational system; (5) time availability and staff capacity; and (6) task division and change coaches. The main professional-reported recommendations were the introduction of tailored and practical IPC guidelines, structural IPC education and training among all professionals, and client participation. CONCLUSIONS To promote IPC, multifaceted and multilevel strategies should be implemented, with a preliminary need for improvements on the guideline, professional, and organisational level. Given the heterogeneous character, i.e., different professionals, clients and care needs, there is a need for a tailored approach to implement IPC and sustain it successfully in disability care. Our findings can inform future IPC practice improvements.

JAC Antimicrob Resist 2021; 3:dlab105. [PMID: 34647021 PMCID: PMC8499689 DOI: 10.1093/jacamr/dlab105] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2021] [Accepted: 06/28/2021] [Indexed: 11/18/2022] Open
Abstract
Background Antibiotic resistance is a growing issue in nursing homes (NHs). Antibiotic
stewardship (ABS) programmes can reduce antibiotic use in NHs, but few
studies have assessed to what extent they are implemented in NHs. Objectives To describe ABS current practices and describe the opinion of NH stakeholders
regarding ABS and opportunities for improvement in one French region. Methods We invited by e-mail the medical and nurse coordinators of all NHs of the
Grand Est region, France, to participate in our survey in 2019. The online
questionnaire included 35 questions covering four topics: NH
characteristics, current ABS practices, attitudes towards ABS and opinions
on strategies to promote ABS. A score evaluating implementation of core ABS
elements was calculated using the current ABS practice responses. Results Out of 417 NHs, 75 (18%) participated in our survey. The three most
implemented ABS activities were antibiotic consumption monitoring
(65%), antibiotic plan documentation (56%) and antibiotic
prescription guide distribution (54%). Audit and feedback, training
sessions or identification of a local ABS leader ranged from 13% to
29%. Participants positively perceived ABS and most suggestions to
improve ABS programmes in NH, with maximal interest in training, audit and
feedback interventions. The median score for implementation of core ABS
elements was 3.3 (IQR = 2.3–5.4; theoretical
range 0–11), and the score distribution was not associated with any
NH characteristic. Conclusions While there is still room for improvement, NHs had a positive attitude
towards ABS strategies. Some regional and national initiatives to promote
ABS in NHs exist and should be actively promoted.

Abstract
Antibiotic overuse and misuse has contributed to rising rates of multidrug-resistant organisms and Clostridioides difficile. Decreasing antibiotic misuse has become a national public health priority. This review outlines the goals of antimicrobial stewardship, essential members of the program, implementation strategies, approaches to measuring the program's impact, and steps needed to build a program. Highlighted is the alliance between antimicrobial stewardship programs and infection prevention programs in their efforts to improve antibiotic use, improve diagnostic stewardship for C difficile and asymptomatic bacteriuria, and decrease health care-associated infections and the spread of multidrug-resistant organisms.

Abstract
BACKGROUND Antibiotic resistance is an increasing threat to public health globally. Indicators on antibiotic prescribing are required to guide antibiotic stewardship interventions in nursing homes. However, such indicators are not available in the literature. Our main objective was to provide a set of quantity metrics and proxy indicators to estimate the volume and appropriateness of antibiotic use in nursing homes. METHODS Recently published articles were first used to select quantity metrics and proxy indicators, which were adapted to the French nursing home context. A cross-sectional observational study was then conducted based on reimbursement databases. We included all community-based nursing homes of the Lorraine region in northeastern France. We present descriptive statistics for quantity metrics and proxy indicators. For proxy indicators, we also assessed performance scores, clinimetric properties (measurability, applicability, and room for improvement), and conducted case-mix and cluster analyses. RESULTS A total of 209 nursing homes were included. We selected 15 quantity metrics and 11 proxy indicators of antibiotic use. The volume of antibiotic use varied greatly between nursing homes. Proxy indicator performance scores were low, and variability between nursing homes was high for all indicators, highlighting important room for improvement. Six of the 11 proxy indicators had good clinimetric properties. Three distinct clusters were identified according to the number of proxy indicators for which the acceptable target was reached. CONCLUSIONS This set of 15 quantity metrics and 11 proxy indicators may be adapted to other contexts and could be used to guide antibiotic stewardship programs in nursing homes.

Abstract
BACKGROUND Antimicrobial overuse/misuse is common in nursing homes and although the effectiveness of antimicrobial stewardship (AMS) programmes has been well explored and demonstrated in hospitals, data are scarce for the nursing-home setting. Our objectives for this systematic review were to make an inventory of: (i) all interventions that could be considered as part of AMS programmes in nursing homes; and (ii) all stewardship tools and guidance that are freely available. METHODS We performed a systematic review using the MEDLINE database from inception to June 2018, including all interventional studies, reviews, opinion pieces and guidelines/guidance exploring AMS programmes in nursing homes. For the inventory of freely available tools and guidance to help implement an AMS programme, we also performed screening of professional societies and official agencies' websites and a questionnaire survey among a panel of international experts. RESULTS A total of 36 articles were included in our systematic review. Most interventions took place in North America and have explored education or persuasive interventions within multifaceted interventions, showing that they can improve guideline adherence and decrease antibiotic use and unnecessary microbiological testing. Most reviews also highlighted the importance of accountability, monitoring and feedback. A large number of tools (156) available for free on the internet were identified, mostly about education, patient assessment and outcome measurement. CONCLUSIONS Although high-quality interventional studies are lacking, multifaceted interventions including education, monitoring and feedback seem the most promising strategy. Many tools are available on the internet and can be used to help implement AMS programmes in nursing homes.

Abstract
BACKGROUND Measuring the appropriateness of antibiotic prescribing in nursing homes remains a challenge. The revised McGeer criteria, which are widely used to conduct infection surveillance in nursing homes, were not designed to assess antibiotic appropriateness. The Loeb criteria were explicitly designed for this purpose but are infrequently used outside investigational studies. The extent to which the revised McGeer and Loeb criteria overlap and can be used interchangeably for tracking antibiotic appropriateness in nursing homes remains insufficiently studied. METHODS We conducted a cross-sectional chart review study in 5 Wisconsin nursing homes and applied the revised McGeer and Loeb criteria to all nursing home-initiated antibiotic treatment courses. Kappa (κ) statistics were employed to assess level of agreement overall and by treatment indications. RESULTS Overall, 734 eligible antibiotic courses were initiated in participating nursing homes during the study period. Of 734 antibiotic courses, 372 (51%) satisfied the Loeb criteria, while only 211 (29%) of 734 satisfied the revised McGeer criteria. Only 169 (23%) of 734 antibiotic courses satisfied both criteria, and the overall level of agreement between them was fair (κ = 0.35). When stratified by infection type, levels of agreement between the revised McGeer and Loeb criteria were moderate for urinary tract infections (κ = 0.45), fair for skin and soft-tissue infections (0.36), and slight for respiratory tract infections (0.17). CONCLUSIONS Agreement between the revised McGeer and Loeb criteria is limited, and nursing homes should employ the revised McGeer and Loeb criteria for their intended purposes. Studies to establish the best method for ongoing monitoring of antibiotic appropriateness in nursing homes are needed.

Abstract
BACKGROUND Urine culturing practices are highly variable in long-term care and contribute to overprescribing of antibiotics for presumed urinary tract infections. The purpose of this study was to evaluate the use of virtual learning collaboratives to support long-term care homes in implementing a quality improvement programme focused on reducing unnecessary urine culturing and antibiotic overprescribing. METHODS Over a 4-month period (May 2018-August 2018), 45 long-term care homes were self-selected from five regions to participate in virtual learning collaborative sessions, which provided an orientation to a quality improvement programme and guidance for implementation. A process evaluation complemented the use of a controlled before-and-after study with a propensity score matched control group (n=127) and a difference-in-difference analysis. Primary outcomes included rates of urine cultures performed and urinary antibiotic prescriptions. Secondary outcomes included rates of emergency department visits, hospital admission and mortality. An 18-month baseline period was compared with a 16-month postimplementation period with the use of administrative data sources. RESULTS Rates of urine culturing and urinary antibiotic prescriptions per 1000 resident days decreased significantly more among long-term care homes that participated in learning collaboratives compared with matched controls (differential reductions of 19% and 13%, respectively, p<0.0001). There was no statistically significant changes to rates of emergency department visits, hospital admissions or mortality. These outcomes were observed with moderate adherence to the programme model. CONCLUSIONS Rates of urine culturing and urinary antibiotic prescriptions declined among long-term care homes that participated in a virtual learning collaborative to support implementation of a quality improvement programme. The results of this study have refined a model to scale this programme in long-term care.

Reducing Fluoroquinolone Use and Clostridioides difficile Infections in Community Nursing Homes Through Hospital-Nursing Home Collaboration. J Am Med Dir Assoc 2021; 21:55-61.e2.

Abstract
OBJECTIVE Nursing homes (NHs) are an important target for antibiotic stewardship (AS). We describe a collaborative model to reduce Clostridioides difficile infections (CDIs) in NHs through optimization of antibiotic use including a reduction in high-risk antibiotics such as fluoroquinolones. DESIGN Quasi-experimental, pre- and post-intervention study. SETTING AND PARTICIPANTS Six NHs in Monroe County, NY. METHODS A hospital-based AS expert team assisted NHs in identifying targets for improving antibiotic use. Interventions included (1) collaboration with a medical director advisory group to develop NH consensus guidelines for testing and treatment of 2 syndromes (urinary tract infections and pneumonia) for which fluoroquinolone use is common, (2) provision of multifaceted NH staff education on these guidelines and education of residents and family members on the judicious use of antibiotics, and (3) sharing facility-specific and comparative antibiotic and CDI data. We used Poisson regression to estimate antibiotic use per 1000 resident days (RD) and CDIs per 10,000 RD, pre- and post-intervention. Segmented regression analysis was used to estimate changes in fluoroquinolone and total antibiotic rates over time. RESULTS Postintervention, the monthly rate of fluoroquinolone days of therapy (DOT) per 1000 RD significantly decreased by 39% [rate ratio (RR) 0.61, 95% confidence interval (CI) 0.59-0.62, P < .001] across all NHs and the total antibiotic DOT decreased by 9% (RR 0.91, 95% CI 0.90-0.92, P < .001). Interrupted time series analysis of fluoroquinolone and total DOT rates confirmed these changes. The quarterly CDI rate decreased by 18% (RR 0.82, 95% CI 0.68-0.99, P = .042). CONCLUSIONS AND IMPLICATIONS A hospital-NH partnership with a medical director advisory group achieved a significant reduction in total antibiotic and fluoroquinolone use and contributed to a reduction in CDI incidence. This approach offers one way for NHs to gain access to AS expertise and resources and to standardize practices within the local community.

Abstract
INTRODUCTION Antimicrobial resistance is a growing global health threat, driven by increasing inappropriate use of antimicrobials. High prevalence of unnecessary use of antimicrobials in residential aged care facilities (RACFs) has driven demand for the development and implementation of antimicrobial stewardship (AMS) programmes. The Stepped-wedge Trial to increase antibiotic Appropriateness in Residential aged care facilities and model Transmission of antimicrobial resistance (START) will implement and evaluate the impact of a nurse-led AMS programme on antimicrobial use in 12 RACFs. METHODS AND ANALYSIS The START trial will implement and evaluate a nurse-led AMS programme via a stepped-wedge cluster randomised controlled trial design in 12 RACFs over 16 months. The AMS programme will incorporate education, aged care-specific treatment guidelines, documentation forms, and audit and feedback strategies that will target aged care staff, general practitioners, pharmacists, and residents and their families. The intervention will primarily focus on urinary tract infections, lower respiratory tract infections, and skin and soft tissue infections. RACFs will transition from control to intervention phases in random order, two at a time, every 2 months, with a 2-month transition, wash-in period. The primary outcome is the cumulative proportion of residents within each facility prescribed an antibiotic during each month and total days of antibiotic use per 1000 occupied bed days. Secondary outcomes include the number of courses of systemic antimicrobial therapy, antimicrobial appropriateness, antimicrobial resistant organisms, Clostridioides difficile infection, change in antimicrobial susceptibility profiles, hospitalisations and all-cause mortality. Analyses will be conducted according to the intention-to-treat principle. ETHICS AND DISSEMINATION Ethics approval has been granted by the Alfred Hospital Human Research Ethics Committee (HREC/18/Alfred/591). Research findings will be disseminated through peer-reviewed publications, conferences and summarised reports provided to participating RACFs. TRIAL REGISTRATION NUMBER NCT03941509.

[PMID: 33549769 DOI: 10.1016/j.jhin.2021.01.019] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Revised: 01/15/2021] [Accepted: 01/15/2021] [Indexed: 12/20/2022]
Abstract
BACKGROUND Suboptimal antibiotic treatment of urinary tract infection (UTI) is high in long-term care facilities (LTCFs) and likely varies between facilities. Large-scale evaluations have not been conducted. AIM To identify facility-level predictors of potentially suboptimal treatment of UTI in Veterans Affairs (VA) LTCFs and to quantify variation across facilities. METHODS This was a retrospective cohort study of 21,938 residents in 120 VA LTCFs (2013-2018) known as Community Living Centers (CLCs). Potentially suboptimal treatment was assessed from drug choice, dose frequency, and/or treatment duration. To identify facility characteristics predictive of suboptimal UTI treatment, LTCFs with higher and lower rates of suboptimal treatment (≥median, < median) were compared using unconditional logistic regression models. Joinpoint regression models were used to quantify average percentage difference across facilities. Multilevel logistic regression models were used to quantify variation across facilities. FINDINGS The rate of potentially suboptimal antibiotic treatment varied from 1.7 to 34.2 per 10,000 bed-days across LTCFs. The average percentage difference in rates across facilities was 2.5% (95% confidence interval (CI): 2.4-2.7). The only facility characteristic predictive of suboptimal treatment was the incident rate of UTI per 10,000 bed-days (odds ratio: 4.9; 95% CI: 2.3-10.3). Multilevel models demonstrated that 94% of the variation between facilities was unexplained after controlling for resident and CLC characteristics. The median odds ratio for the full multilevel model was 1.37. CONCLUSION Potentially suboptimal UTI treatment was variable across VA LTCFs. However, most of the variation across LTCFs was unexplained. Future research should continue to investigate factors that are driving suboptimal antibiotic treatment in LTCFs.

Abstract
OBJECTIVES Characterize key tasks and information needs for heart failure disease management (HF-DM) in the distinct care setting of skilled nursing facility (SNF) staff in partnership with community-based clinical stakeholders. Develop design recommendations contextualized to the SNF setting for informatics interventions for improved HF-DM in the SNF setting. METHODS Semi-structured interviews with fifteen participants (registered nurses, licensed practical nurses, certified nursing aides and physicians) from 8 Denver-metro SNFs. Data coded using a data-driven, inductive approach. RESULTS Key tasks of HF-DM: symptom assessment, communicating change in condition, using equipment, documentation of daily weights, and monitoring patients. Themes: 1) HF-DM is challenged by a culture of verbal communication; 2) staff face knowledge barriers in HF-DM that are partially attributed to unmet information needs. HF-DM information needs: identification of HF patients, HF signs and symptoms, purpose of daily weights, indicators of worsening HF, purpose of sodium restricted diet, and materials to improve patients' understanding of HF. DISCUSSION AND CONCLUSIONS HF-DM information needs are not fully supported by current SNF information systems.

Abstract
BACKGROUND In long-term care facilities (LTCFs) residents often receive inappropriate antibiotic treatment and infection prevention and control practices are frequently inadequate, thus favouring acquisition of MDR organisms. There is increasing evidence in the literature describing antimicrobial stewardship (AMS) activities in LTCFs, but practical guidance on how surveillance data should be linked with AMS activities in this setting is lacking. To bridge this gap, the JPIAMR ARCH and COMBACTE-MAGNET EPI-Net networks joined their efforts to provide practical guidance for linking surveillance data with AMS activities. MATERIALS AND METHODS Considering the three main topics [AMS leadership and accountability, antimicrobial usage (AMU) and AMS, and antimicrobial resistance (AMR) and AMS], a literature review was performed and a list of target actions was developed. Consensus on target actions was reached through a RAND-modified Delphi process involving 40 experts from 18 countries and different professional backgrounds adopting a One Health approach. RESULTS From the 25 documents identified, 25 target actions were retrieved and proposed for expert evaluation. The consensus process produced a practical checklist including 23 target actions, differentiating between essential and desirable targets according to clinical relevance and feasibility. Flexible proposals for AMS team composition and leadership were provided, with a strong emphasis on the need for well-defined and adequately supported roles and responsibilities. Specific antimicrobial classes, AMU metrics, pathogens and resistance patterns to be monitored are addressed. Effective reporting strategies are described. CONCLUSIONS The proposed checklist represents a practical tool to support local AMS teams across a wide range of care delivery organization and availability of resources.

Abstract
Successful antimicrobial stewardship programs must be a truly collaborative multidisciplinary team effort. Nurses have critical contributions and are recognized more in publications about antimicrobial stewardship. Examination of patient care workflow patterns indicates the central role of nurses in the application of stewardship concepts in patient care. Education about antimicrobial resistance and antimicrobial stewardship is important not only for nurses and other health care providers but also for the general public. Analysis of the health care workforce population shows the importance of integrating this largest segment of health care providers in the routine daily care of patients into all stewardship efforts.

Abstract
Background: Prevalence of extended-spectrum beta-lactamase-producing Escherichia coli (ESBL-E. coli) is increasing worldwide, but greatly varies geographically. We compared the prevalence of ESBL-E. coli infections at four distinct health care facilities in San Francisco, California. Methods: Antimicrobial susceptibility reports were obtained for E. coli isolates from (1) a county hospital, (2) a public skilled nursing facility, (3) a university hospital, and (4) a Veterans Affairs (VA) Medical Center. We compared change in frequency of ESBL-E. coli and antimicrobial resistance to trimethoprim-sulfamethoxazole between 2012 and 2018. Results: From 2012 to 2018, frequency of ESBL-E. coli increased in urine and nonurine isolates from the county hospital (urine: 1.1% per year, 95% confidence interval [CI]: 0.5-1.6, p < 0.01; nonurine: 1.9% per year, 95% CI: 0.9-2.9, p < 0.01) and in urine isolates from the VA hospital (0.9% per year, 95% CI: 0.3-1.4, p < 0.01). The frequency of trimethoprim-sulfamethoxazole resistance fluctuated in all facilities. Conclusions: At the skilled nursing facility, the prevalence of ESBL-E. coli was highest, but remained stable over time, while the prevalence of ESBL-E. coli increased among urine and nonurine isolates at the county hospital and urine isolates at the VA hospital. The temporal trend of ESBL-E. coli infections, even within one city, varied by health care facility.

Abstract
Long-term care facilities are significant reservoirs of antimicrobial-resistant organisms, and patients with advanced dementia are particularly vulnerable to multidrug-resistant organism (MDRO) acquisition and antimicrobial overuse. In this study, we longitudinally examined a group of patients with advanced dementia using metagenomic sequencing. We found significant inter- and intra-subject heterogeneity in microbiota composition, suggesting temporal instability. We also observed a link between the antimicrobial resistance gene density in a sample and the relative abundances of several pathobionts, particularly Escherichia coli, Proteus mirabilis, and Enterococcus faecalis, and used this relationship to predict resistance gene density in samples from additional subjects. Furthermore, we used metagenomic assembly to demonstrate that these pathobionts had higher resistance gene content than many gut commensals. Given the frequency and abundances at which these pathobionts were found in this population and the underlying vulnerability to MDRO of patients with advanced dementia, attention to microbial blooms of these species may be warranted.

Abstract
BackgroundThe most frequent acute health-care intervention that care home residents receive is the prescribing of medications. There are serious concerns about prescribing generally, and about antimicrobial prescribing in particular, with facilities such as care homes being described as an important ‘reservoir’ of antimicrobial resistance.ObjectivesTo evaluate the feasibility and acceptability of a multifaceted intervention on the prescribing of antimicrobials for the treatment of infections.DesignThis was a non-randomised feasibility study, using a mixed-methods design with normalization process theory as the underpinning theoretical framework and consisting of a number of interlinked strands: (1) recruitment of care homes; (2) adaptation of a Canadian intervention (a decision-making algorithm and an associated training programme) for implementation in UK care homes through rapid reviews of the literature, focus groups/interviews with care home staff, family members of residents and general practitioners (GPs), a consensus group with health-care professionals and development of a training programme; (3) implementation of the intervention; (4) a process evaluation consisting of observations of practice and focus groups with staff post implementation; and (5) a survey of a sample of care homes to ascertain interest in a larger study.SettingSix care homes – three in Northern Ireland and three in the West Midlands.ParticipantsCare home staff, GPs associated with the care homes and family members of residents.InterventionsA training programme for care home staff in the use of the decision-making algorithm, and implementation of the decision-making algorithm over a 6-month period in the six participating care homes. REACH (REduce Antimicrobial prescribing in Care Homes) Champions were appointed in each care home to support intervention implementation and the training of staff.Main outcome measuresThe acceptability of the intervention in terms of recruitment, delivery of training, feasibility of data collection from a variety of sources, implementation, practicality of use and the feasibility of measuring the appropriateness of prescribing.ResultsSix care homes from two jurisdictions were recruited, and the intervention was adapted and implemented. The intervention appeared to be broadly acceptable and was implemented largely as intended, although staff were concerned about the workload associated with study documentation. It was feasible to collect data from community pharmacies and care homes, but hospitalisation data from administrative sources could not be obtained. The survey indicated that there was interest in participating in a larger study.ConclusionsThe adapted and implemented intervention was largely acceptable to care home staff. Approaches to minimising the data-collection burden on staff will be examined, together with access to a range of data sources, with a view to conducting a larger randomised study.Trial registrationCurrent Controlled Trials ISRCTN10441831.FundingThis project was funded by the National Institute for Health Research (NIHR) Health Services and Delivery Research programme and will be published in full inHealth Services and Delivery Research; Vol. 8, No. 8.

Abstract
OBJECTIVE Burgeoning rates of antibiotic resistance have resulted in a shift in national focus to improve infection prevention and control programs in US nursing homes (NHs). We sought to evaluate the changes in nursing home infection prevention and control programs over time. DESIGN Retrospective comparative analysis of national nursing home survey data from 2014 and 2018. SETTING AND PARTICIPANTS We used survey data from 2 nationally representative samples of US nursing homes (945 NHs in 2014 and 888 in 2018). METHODS Three indices measuring antibiotic stewardship, outbreak control, and urinary tract infection prevention (ranging from 0 to 100) were developed to measure the change in infection prevention and control programs. Multivariable linear regression models were used to identify facility and infection preventionist characteristics associated with each index. Decomposition models were used to identify contributions of factors on the differences in each index over time. RESULTS From 2014 to 2018, we saw strengthening of antibiotic stewardship practices by 33 percentage points, outbreak control practices by 13 percentage points, and urinary tract infection prevention practices by 6 percentage points. Although we found several predictors of these improvements, much of the improvement was due to the difference in time. CONCLUSIONS AND IMPLICATIONS Policy mandates and greater national attention are likely important factors in improving nursing home infection prevention and control practices. Further work is needed to evaluate the effect of these programs on resident outcomes.

Abstract
BACKGROUND Prescribing patterns for episodic medications, such as antibiotics, might make useful surrogate measures of a physician's overall prescribing practice because use is common, and variation exists across prescribers. However, the extent to which a physician's current antibiotic prescribing practices are associated with the rate of prescription of other potentially harmful medications remains unknown. OBJECTIVE To examine the association between a physician's rate of antibiotic prescribing and their prescribing rate of benzodiazepines, opioids and proton-pump inhibitors in older adults. DESIGN Population-based cohort study in nursing homes in Ontario, Canada, which provides comprehensive clinical, behavioural and functional information on all patients. PARTICIPANTS 1926 physicians who provided care among 128,979 physician-patient pairs in 2015. MAIN MEASURES Likelihood of prescribing a benzodiazepine, opioid or proton-pump inhibitor between low-, average- and high-intensity antibiotic prescribers, adjusted for patient characteristics. KEY RESULTS Compared with average-intensity antibiotic prescribers, high-intensity prescribers had an increased likelihood of prescribing a benzodiazepine (odds ratio 1.21 [95% CI, 1.11-1.32]), an opioid (odds ratio 1.28 [95% CI, 1.17-1.39]) or a proton-pump inhibitor (odds ratio 1.38 [95% CI, 1.27-1.51]]. High-intensity antibiotic prescribers were more likely to be high prescribers of all three medications (odds ratio 6.24 [95% CI, 2.90-13.39]) and also more likely to initiate all three medications, compared with average-intensity prescribers. CONCLUSIONS The intensity of a physician's episodic antibiotic prescribing was significantly associated with the likelihood of new and continued prescribing of opioids, benzodiazepines and proton-pump inhibitors in nursing homes. Patterns of episodic prescribing may be a useful mechanism to target physician-level interventions to optimize general prescribing behaviors, instead of prescribing behaviors for single medications.

Abstract
BACKGROUND AND OBJECTIVES Clinical decision support systems (CDSS) hold promise to influence clinician behavior at the point of care in nursing homes (NHs) and improving care delivery. However, the success of these interventions depends on their fit with workflow. The purpose of this study was to characterize workflow in NHs and identify implications of workflow for the design and implementation of CDSS in NHs. RESEARCH DESIGN AND METHODS We conducted a descriptive study at 2 NHs in a metropolitan area of the Mountain West Region of the United States. We characterized clinical workflow in NHs, conducting 18 observation sessions and interviewing 15 staff members. A multilevel work model guided our data collection and framework method guided data analysis. RESULTS The qualitative analysis revealed specific aspects of multilevel workflow in NHs: (a) individual, (b) work group/unit, (c) organization, and (d) industry levels. Data analysis also revealed several additional themes regarding workflow in NHs: centrality of ongoing relationships of staff members with the residents to care delivery in NHs, resident-centeredness of care, absence of memory aids, and impact of staff members' preferences on work activities. We also identified workflow-related differences between the two settings. DISCUSSION AND IMPLICATIONS Results of this study provide a rich understanding of the characteristics of workflow in NHs at multiple levels. The design of CDSS in NHs should be informed by factors at multiple levels as well as the emergent processes and contextual factors. This understanding can allow for incorporating workflow considerations into CDSS design and implementation.

Abstract
Antimicrobial stewardship improves patient care and reduces antimicrobial resistance, inappropriate use, and adverse outcomes. Despite high-profile mandates for antimicrobial stewardship programs across the healthcare continuum, descriptive data, and recommendations for dedicated resources, including appropriate physician, pharmacist, data analytics, and administrative staffing support, are not robust. This review summarizes the current literature on antimicrobial stewardship staffing and calls for the development of minimum staffing recommendations.

Abstract
Antibiotics are commonly prescribed among older adults, and inappropriate use of antibiotics has been noted. However, there is limited information about their knowledge and expectations for antibiotics. This study aimed to assess older adults' knowledge of antibiotic use and resistance, their expectations for antibiotics and the relationship between knowledge, expectation and inappropriate practices related to antibiotic use. A cross-sectional survey involving respondents aged 60 years and above was conducted, using a validated questionnaire. A lack of knowledge about the role of antibiotics was observed, whereby more than half of the respondents incorrectly believed that antibiotics can treat viral infections (53.5%) and colds and coughs (53.7%). Also, 67.9% of respondents incorrectly believed that antibiotic resistance occurs when the body becomes resistant to antibiotics. Almost half of the respondents would expect antibiotics for symptoms of self-limiting viral infections. Respondents who answered correctly for the role of antibiotics in viral infections were more likely not to expect antibiotics for cold, flu and cough (p < 0.001). Respondents who answered correctly regarding the need to adhere to antibiotics were more likely to have completed their antibiotic course (p < 0.001). Future educational initiatives should provide key information on the role of antibiotics and the importance of complying with antibiotics in this population.

Abstract
OBJECTIVE To describe urinary tract infection (UTI) treatment among Veterans' Affairs (VA) Community Living Centers (CLCs) nationally and to assess related trends in antibiotic use. DESIGN Descriptive study. SETTING AND PARTICIPANTS All UTI episodes treated from 2013 through 2017 among residents in 110 VA CLCs. UTI episodes required collection of a urine culture, antibiotic treatment, and a UTI diagnosis code. UTI episodes were stratified into culture-positive and culture-negative episodes. METHODS Frequency and rate of antibiotic use were assessed for all UTI episodes overall and were stratified by culture-positive and culture-negative episodes. Joinpoint software was used for regression analyses of trends over time. RESULTS We identified 28,247 UTI episodes in 14,983 Veterans. The average age of Veterans was 75.7 years, and 95.9% were male. Approximately half of UTI episodes (45.7%) were culture positive and 25.7% were culture negative. Escherichia coli was recovered in 34.1% of culture-positive UTI episodes, followed by Proteus mirabilis and Klebsiella spp, which were recovered in 24.5% and 17.4% of culture-positive UTI episodes, respectively. The rate of total antibiotic use in days of therapy (DOT) per 1,000 bed days decreased by 10.1% per year (95% CI, -13.6% to -6.5%) and fluoroquinolone use (ciprofloxacin or levofloxacin) decreased by 14.5% per year (95% CI, -20.6% to -7.8%) among UTI episodes overall. Similar reductions in rates of total antibiotic use and fluoroquinolone use were observed among culture-positive UTI episodes and among culture-negative UTI episodes. CONCLUSION Over a 5-year period, antibiotic use for UTIs significantly decreased among VA CLCs, as did use of fluoroquinolones. Antibiotic stewardship efforts across VA CLCs should be applauded, and these efforts should continue.

Decrease in Antibacterial Use and Facility-Level Variability After the Introduction of Guidelines and Implementation of Physician-Pharmacist-Nurse Quality Circles in Swiss Long-term Care Facilities. J Am Med Dir Assoc 2019; 21:78-83. [PMID: 31327571 DOI: 10.1016/j.jamda.2019.05.016] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2018] [Revised: 05/16/2019] [Accepted: 05/18/2019] [Indexed: 11/24/2022]
Abstract
OBJECTIVES The objective of this study is to describe antibacterial use in long-term care facilities and to investigate the determinants of use. DESIGN This study is a quality improvement study conducted from January 2011 to December 2016. SETTING Long-term care facilities in the canton of Vaud, Western Switzerland, were investigated. PARTICIPANTS Twenty-three long-term care facilities were included in this study. INTERVENTION The intervention included the publication of local guidelines on empirical antibacterial therapy and the implementation of physician-pharmacist-nurse quality circles. MEASURES The main outcome was antibacterial use, expressed as defined daily doses (DDD) per 1000 beds per day. Statistical analyses were performed through a 1-level mixed model for repeated measurements. RESULTS Antibacterial use decreased from 45.6 to 35.5 DDD per 1000 beds per day (-22%, P < .01) over the 6-year study period, which was mostly explained by reduced fluoroquinolone use (-59%, P < .001). A decrease in range of use among LTCFs was observed during the study period, and 27% of antibacterial use was related to the WATCH group (antibiotics with higher toxicity concerns and/or resistance potential) according to the AWaRe categorization of the WHO, decreasing from 17.3 DDD per 1000 beds per day to 9.5 (-45%) over the study period. The use of antibacterials from the RESERVE group ("last-resort" treatment options) was very low. CONCLUSION AND IMPLICATIONS A reduction in facility-level antibacterial use and in variability across LTCFs was observed over the study period. The dissemination of empirical antibacterial prescription guidelines and the implementation of physician-pharmacist-nurse quality circles in all LTCFs of the canton of Vaud likely contributed to this reduction. Antibacterials from the WATCH group still represented 27% of the total use, providing targets for future antibiotic stewardship activities.

Abstract
Drug-resistant bacteria are a serious threat to global public health. Gram-positive bacterial endolysin preparations have been successfully used to fight Gram-positive bacteria as a novel antimicrobial replacement strategy. However, Gram-negative bacterial phage endolysins cannot be applied directly to destroy Gram-negative strains due to the externally inaccessible peptidoglycan layer of the cell wall; this has seriously hampered the development of endolysin-like antibiotics against Gram-negative bacteria. In this study, 3–12 hydrophobic amino acids were successively added to the C-terminus of Escherichia coli phage endolysin Lysep3 to create five different hydrophobic-modified endolysins. Compared with endogenous Lysep3, endolysins modified with hydrophobic amino acids surprisingly could kill E. coli from outside of the cell at the appropriate pH and endolysin concentration. The lysis ability of modified endolysins were enhanced with increasing numbers of hydrophobic amino acids at the C-terminus of endolysin. Thus, these findings demonstrate that the enhancement of hydrophobicity at the C-terminus enables the endolysin to act upon E. coli from the outside, representing a novel method of lysing Gram-negative antibiotic-resistant bacteria.

Abstract
The aim of the current study was to conduct usability testing of a mobile clinical decision support (CDS) prototype designed for urinary tract infection (UTI) assessment by nurses in nursing homes (NHs). Usability of the UTIDecide smartphone application (app) was evaluated using cognitive walk-through and think-aloud protocol sessions with nurses (n = 6) at two NH sites. This evaluation was followed by unsupervised field tests lasting ≥1 week with nurses at one site (n = 4) and posttest interviews and administration of the System Usability Scale (SUS). Cognitive walk-through/think-aloud sessions yielded interface design recommendations that were implemented prior to field tests. All test sessions resulted in highly positive perceived usability and usefulness from participants. Average SUS score was 92.5 (n = 3), which equates to an "A" grade for usability. Design recommendations identified for future app versions are: (a) integration of the mobile CDS app with organizational information systems; and (b) expanded features to support assessment of other conditions.

Abstract
OBJECTIVES To investigate potential effects and acceptability of a theoretically driven hydration intervention (DRInK-Up), on the prevalence of urinary tract infections (UTIs), falls and emergency admissions in care home residents. METHODS A single group pre-post evaluation design to test the DRInK-Up intervention, to increase fluid intake by 200-400ml daily. The number of UTIs, falls and emergency hospital admissions for each resident recorded over the DRInK-Up intervention period were compared to rates in the 24 weeks prior. A qualitative investigation of experiences of DRInK-Up was undertaken using focus group interviews with care home staff to determine acceptability. RESULTS 24 care home residents took part in the intervention. There was a clinically meaningful, but non-statistically significant reduction in number of treated UTIs during the intervention period from 51 UTIs pre-DRInK-Up to 37 post-DRInK-Up (t= .498, 18df, p=0.625). The volume of fluid intake recorded was not correlated with number of UTIs (r= 0.103, p=.676). Falls reported dropped from 52 pre- to 28 post-intervention (t=3.148, df 19, p=0.005). Emergency admissions did not change. Focus group interviews suggested goal setting was uncommon and took the form of externally generated targets for fluid intake rather than negotiated goals. Barriers to increasing fluid intake included resident-related factors or arose from the care home context. A range of facilitators included verbal persuasion, praise and reward. CONCLUSION The DRInK-Up study provides preliminary evidence suggesting that increasing daily fluid intake by small amounts may have a potentially positive effect on number of UTIs experienced and number of falls in frail older care home residents. Further research is needed.

Abstract
BACKGROUND Mathematical transmission models are increasingly used to guide public health interventions for infectious diseases, particularly in the context of emerging pathogens; however, the contribution of modeling to the growing issue of antimicrobial resistance (AMR) remains unclear. Here, we systematically evaluate publications on population-level transmission models of AMR over a recent period (2006-2016) to gauge the state of research and identify gaps warranting further work. METHODS We performed a systematic literature search of relevant databases to identify transmission studies of AMR in viral, bacterial, and parasitic disease systems. We analyzed the temporal, geographic, and subject matter trends, described the predominant medical and behavioral interventions studied, and identified central findings relating to key pathogens. RESULTS We identified 273 modeling studies; the majority of which (> 70%) focused on 5 infectious diseases (human immunodeficiency virus (HIV), influenza virus, Plasmodium falciparum (malaria), Mycobacterium tuberculosis (TB), and methicillin-resistant Staphylococcus aureus (MRSA)). AMR studies of influenza and nosocomial pathogens were mainly set in industrialized nations, while HIV, TB, and malaria studies were heavily skewed towards developing countries. The majority of articles focused on AMR exclusively in humans (89%), either in community (58%) or healthcare (27%) settings. Model systems were largely compartmental (76%) and deterministic (66%). Only 43% of models were calibrated against epidemiological data, and few were validated against out-of-sample datasets (14%). The interventions considered were primarily the impact of different drug regimens, hygiene and infection control measures, screening, and diagnostics, while few studies addressed de novo resistance, vaccination strategies, economic, or behavioral changes to reduce antibiotic use in humans and animals. CONCLUSIONS The AMR modeling literature concentrates on disease systems where resistance has been long-established, while few studies pro-actively address recent rise in resistance in new pathogens or explore upstream strategies to reduce overall antibiotic consumption. Notable gaps include research on emerging resistance in Enterobacteriaceae and Neisseria gonorrhoeae; AMR transmission at the animal-human interface, particularly in agricultural and veterinary settings; transmission between hospitals and the community; the role of environmental factors in AMR transmission; and the potential of vaccines to combat AMR.

Abstract
BACKGROUND The exponential increase in the number of medications associated with clinically important prolongation of the heart rate-corrected QT interval (QTc) places older adults at increased risk of arrhythmias including life-threatening torsade de pointes (TdP) and sudden death. Risk factors, other than age older than 65 years and female sex, include multiple concurrent drugs that prolong QTc and a variety of underlying predisposing conditions. Although electronic medical records and pharmacy dispensing systems can alert clinicians to the risk of QTc-prolonging therapy, more than 95% of safety alerts are overridden, and many systems have deactivated QTc drug interaction alerts. The clinical consequences, magnitude of the effect, mitigation strategies, and recommended monitoring are not well defined for nursing facility (NF) residents. DESIGN Narrative review. SETTING NFs in the United States. PARTICIPANTS NF residents. RESULTS Medications known to prolong QTc include selected anti-infectives, antidepressants, urinary anticholinergics, antipsychotics, and cholinesterase inhibitors (eg, donepezil), used commonly in NFs. Drug-drug interactions are a risk when adding a medication that exaggerates the effect or inhibits the metabolism of a QTc-prolonging medication. The vast majority of patients in whom TdP is induced by noncardiac drugs have risk factors that are easily identifiable. CONCLUSIONS Recommendations are provided to improve standardization and use of drug interaction alerts, evaluate the risk of QTc-prolonging drugs in older adults receiving generally lower doses, validate a QTc risk score addressing complex multimorbidity, garner evidence to guide clinical decision making, avail NFs of access to electrocardiograms and interpretive recommendations, and develop standards of practice for hosting risk discussions with residents and their families.

Abstract
OBJECTIVE To quantify the frequency and outcomes of receiving an antibiotic prescription upon discharge from the hospital to long-term care facilities (LTCFs). DESIGN Retrospective cohort study. SETTING A 576-bed, academic hospital in Portland, Oregon.PatientsAdult inpatients (≥18 years of age) discharged to an LTCF between January 1, 2012, and June 30, 2016. METHODS Our primary outcome was receiving a systemic antibiotic prescription upon discharge to an LTCF. We also quantified the association between receiving an antibiotic prescription and 30-day hospital readmission, 30-day emergency department (ED) visit, and Clostridium difficile infection (CDI) on a readmission or ED visit at the index facility within 60 days of discharge. RESULTS Among 6,701 discharges to an LTCF, 22.9% were prescribed antibiotics upon discharge. The most prevalent antibiotic classes prescribed were cephalosporins (20.4%), fluoroquinolones (19.1%), and penicillins (16.7%). The medical records of ~82% of patients included a diagnosis code for a bacterial infection on the index admission. Among patients prescribed an antibiotic upon discharge, the incidence of 30-day hospital readmission to the index facility was 15.9%, the incidence of 30-day ED visit at the index facility was 11.0%, and the incidence of CDI on a readmission or ED visit within 60 days of discharge was 1.6%. Receiving an antibiotic prescription upon discharge was significantly associated with 30-day ED visits (adjusted odds ratio [aOR], 1.2; 95% confidence interval [CI], 1.02-1.5) and with CDI within 60 days (aOR, 1.7; 95% CI, 1.02-2.8) but not with 30-day readmissions (aOR, 1.01; 95% CI, 0.9-1.2). CONCLUSIONS Antibiotics were frequently prescribed upon discharge to LTCFs, which may be associated with increased risk of poor outcomes post discharge.

Abstract
Background Urinary tract infections (UTIs) are the most prevalent infections in long-term care facilities (LTCFs). Numerous studies have described the problem of inadequate UTI diagnosis and treatment. We assessed the role of urine cultures in the diagnosis and treatment of UTIs in a LTCF. Methods In a 370-bed non-academic LTCF a retrospective assessment of antibiotic (AB) prescriptions for UTIs and urine cultures was performed from July 2014 to January 2016. The reasons why physicians, including 11 nursing home physicians and 2 junior doctors, ordered urine cultures were recorded using questionnaires. Results During the study period, 378 residents were prescribed 1672 AB courses; 803 were for UTIs. One hundred and fifty-five urine cultures were obtained from 135 residents; 66 of these cultures were performed on the same day as ABs were prescribed (8% of all prescriptions for UTI), while 89 were not. There was a discrepancy between the actions that seemed logical based on the culture results and the actions that were actually taken in 75% of the cases. In these cases, initial AB treatment was not adjusted when the isolated microorganism was resistant to the AB prescribed, the urine culture was positive and no ABs had previously been administered, or ABs were prescribed and no microorganism was isolated. The most frequent reason for ordering a urine culture was to confirm the diagnosis of a UTI. Conclusion In the majority of patients, AB therapy was not adjusted when the urine culture results suggested it may be appropriate. The physicians were erroneously convinced that UTIs could be diagnosed by a positive urine culture.

Abstract
Background As antibiotics progressively cease to be effective, silver based nanoparticles (SBNs), with broad antibacterial spectrum, might be the last line of defense against malicious bacteria. Unfortunately, there are still no proper SBNs-based strategies for in vivo antibacterial therapies. In this article, new carbon membrane packaged Ag nanoparticles (Ag-C) were synthesized. We assessed the effect of Ag-C with NaCl on size, cytotoxicity, antibacterial properties, metabolism and sepsis models. Methods The size of Ag-C with NaCl was accessed with UV-vis, TEM and SEM. Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa were used to illustrate the antibacterial properties of SBNs affected by NaCl. L929 and 3T3 cell lines were cultured in vitro; CCK-8 assay was used to test cytotoxicity. Then, we explored the metabolism of Ag-C with NaCl in vivo. Finally, the effect of Ag-C with 4× NaCl on sepsis was observed. Results NaCl could regulate the size of Ag-C. Ag-C exhibited superior antibacterial properties compared to similar sized pure Ag nanoparticles. Furthermore, the addition of NaCl could not only reduce the cytotoxicity of Ag-C, but could also continue to discharge Ag-C from major organs. Based on these factors, this method was used to treat a sepsis model (induced via cecal ligation and puncture), and it achieved satisfactory survival results. Conclusion This discovery, though still in its infancy, could significantly improve the safety and feasibility of SBNs and could potentially play an important role in modern in vivo antibacterial applications. Thus, a new method to combating the growing threat from drug-resistant bacteria could be possible. NaCl is the key to excretion of SBNs after in vivo antibacterial use.

Hospital-associated methicillin-resistant Staphylococcus aureus: A cross-sectional analysis of risk factors in South African tertiary public hospitals. PLoS One 2017; 12:e0188216. [PMID: 29145465 PMCID: PMC5690649 DOI: 10.1371/journal.pone.0188216] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/07/2017] [Accepted: 11/02/2017] [Indexed: 12/27/2022] Open
Abstract
Introduction Hospital-associated methicillin-resistant S. aureus (HA-MRSA) remains a significant cause of morbidity and mortality worldwide. We conducted a study to determine risk factors for HA-MRSA in order to inform control strategies in South Africa. Methods We used surveillance data collected from five tertiary hospitals in Gauteng and Western Cape provinces during 2014 for analysis. A case of HA-MRSA was defined as isolation of MRSA from a blood culture 48 hours after admission and/or if the patient was hospitalised in the six months prior to the current culture. Multivariable logistic regression modelling was used to determine risk factors for HA-MRSA. Results Of the 9971 patients with positive blood cultures, 7.7% (772) had S. aureus bacteraemia (SAB). The overall prevalence of MRSA among those with SAB was 30.9% (231/747; 95% confidence interval [CI] 27.6%– 34.3%). HA-MRSA infections accounted for 28.3% of patients with SAB (207/731; 95% CI 25.1%– 31.7%). Burns (adjusted odds ratio [aOR] 12.7; 95% CI 4.7–34.4), age ≤1 month (aOR 8.7; 95% CI 3.0–24.6), residency at a long-term care facility (aOR 5.2; 95% CI, 1.5–17.4), antibiotic use within two months of the current SAB episode (aOR 5.1; 95% CI 2.8–9.1), hospital stay of 13 days or more (aOR 2.8; 95% CI 1.3–5.6) and mechanical ventilation (aOR 2.2; 95% CI 1.07–4.6), were independent risk factors for HA-MRSA infection. Conclusion The prevalence of MRSA remains high in South African tertiary public hospitals. Several identified risk factors of HA-MRSA infections should be considered when instituting infection and prevention strategies in public-sector hospitals, including intensifying the implementation of antimicrobial stewardship programmes. There is an urgent need to strengthen infection prevention and control in burn wards, neonatal wards, and intensive care units which house mechanically ventilated patients.

Abstract
BACKGROUND Unique characteristics of nursing homes (NHs) contribute to high rates of inappropriate antibiotic use for asymptomatic bacteriuria (ASB), a benign condition. A mobile clinical decision support system (CDSS) may support NH staff in differentiating urinary tract infections (UTI) from ASB and reducing antibiotic days. OBJECTIVES We used Goal-Directed Design to: 1) Characterize information needs for UTI identification and management in NHs; 2) Develop UTI Decide, a mobile CDSS prototype informed by personas and scenarios of use constructed from Aim 1 findings; 3) Evaluate the UTI Decide prototype with NH staff. METHODS Focus groups were conducted with providers and nurses in NHs in Denver, Colorado (n= 24). Qualitative descriptive analysis was applied to focus group transcripts to identify information needs and themes related to mobile clinical decision support for UTI identification and management. Personas representing typical end users were developed; typical clinical context scenarios were constructed using information needs as goals. Usability testing was performed using cognitive walk-throughs and a think-aloud protocol. RESULTS Four information needs were identified including guidance regarding resident assessment; communication with providers; care planning; and urine culture interpretation. Design of a web-based application incorporating a published decision support algorithm for evidence-based UTI diagnoses proceeded with a focus on nursing information needs during resident assessment and communication with providers. Certified nursing assistant (CNA) and registered nurse (RN) personas were constructed in 4 context scenarios with associated key path scenarios. After field testing, a high fidelity prototype of UTI Decide was completed and evaluated by potential end users. Design recommendations and content recommendations were elicited. CONCLUSIONS Goal-Directed Design informed the development of a mobile CDSS supporting participant-identified information needs for UTI assessment and communication in NHs. Future work will include iterative deployment and evaluation of UTI Decide in NHs to decrease inappropriate use of antibiotics for suspected UTI.

Abstract
BACKGROUND Hand hygiene is the single-most important nursing home (NH) infection control measure. We piloted a multifaceted hand-washing/surface cleaning intervention in 5 NHs. Our aims were to assess the feasibility of implementing this intervention by assessing staff participation, satisfaction, hand-washing compliance, and whether the intervention was associated with reductions in infection rates, new antimicrobial orders, or overall hospitalization rates. METHODS We conducted a randomized, pair-matched pilot intervention in 10 Colorado NHs to reduce infections for all NH residents from October 1, 2015 through May 31, 2016. To evaluate process, we determined online education participation rates, recorded intervention fidelity through weekly reporting measures on microbial surface counts, hand-washing, and infection reporting, and conducted a survey of participating employees. To evaluate potential impacts on clinical outcomes, we collected information on monthly infection log data, new antibiotic orders, and hospitalizations. RESULTS Three of 5 sites had education participation rates >90%, the other 2 were poor (13% and 23%). The majority of participation survey respondents (58%) were promoters of the intervention. Directors of nursing reported hygiene hand-washing data for 19.6/24 (81.8%) weeks and microbial surface count data for 20.4/24 (85.1%) weeks. For the first 4 weeks of the study, the bacterial counts averaged 351.4 ± 497.5 relative light units, the mean value for the last 4 weeks was 127.7 ± 85.1 (P value = .12). The number of hand-washing occasions per NH resident was steady over time but differed by treatment facility (P = .03). We observed nonsignificant reductions for total infections (6.7%) and lower respiratory tract infections (19.9%) vs control NHs. There were no significant differences in antimicrobial orders or hospitalization rates pre-post intervention. CONCLUSIONS This multifaceted hand-washing and surface cleaning intervention was designed to reduce infection rates among NH residents. In our 10-facility randomized, matched pair pilot study, we observed program compliance and satisfaction along with reductions in surface bacterial counts, but did not observe a statistically significant reduction in infection rates, antimicrobial use, or hospitalizations.
