RESUMO
AIM: To assess infection prevention and control programs in residential aged care facilities. METHODS: A cross-sectional survey and structured interviews from 10 residential aged care facilities in Victoria, Australia, were used. Infection prevention and control nurse leads from each facility completed a purpose-built survey based on best practice infection prevention control program core components, including staff training, policies and procedures, governance, and surveillance. Follow-up interviews with residential aged care staff, residents and family visitors were carried out to elaborate and verify survey data. RESULTS: Surveys from all 10 facilities were received and 75 interviews carried out. All facilities had an infection prevention and control lead nurse who had undergone additional training, and 60% of facilities had an infection prevention and control lead position description. All facilities had a committee to oversee their infection prevention and control program, and all had policies and procedures for standard and transmission-based precautions. One facility did not have a policy on healthcare-associated infection surveillance, and two facilities did not have an antimicrobial stewardship policy. All facilities provided staff training in hand hygiene and personal protective equipment use, but not all routinely assessed competency in these. CONCLUSIONS: The residential aged care facilities' infection prevention and control programs were generally in a strong position, although there were some areas that require improvement. Further assessment of the quality of infection prevention and control program components, such as content of education and training, and policies and procedures, and ongoing evaluation of programs is recommended.

BACKGROUND: The addition of vancomycin to beta-lactam prophylaxis in arthroplasty may reduce surgical-site infections; however, the efficacy and safety are unclear. METHODS: In this multicenter, double-blind, superiority, placebo-controlled trial, we randomly assigned adult patients without known methicillin-resistant Staphylococcus aureus (MRSA) colonization who were undergoing arthroplasty to receive 1.5 g of vancomycin or normal saline placebo, in addition to cefazolin prophylaxis. The primary outcome was surgical-site infection within 90 days after surgery. RESULTS: A total of 4239 patients underwent randomization. Among 4113 patients in the modified intention-to-treat population (2233 undergoing knee arthroplasty, 1850 undergoing hip arthroplasty, and 30 undergoing shoulder arthroplasty), surgical-site infections occurred in 91 of 2044 patients (4.5%) in the vancomycin group and in 72 of 2069 patients (3.5%) in the placebo group (relative risk, 1.28; 95% confidence interval [CI], 0.94 to 1.73; P = 0.11). Among patients undergoing knee arthroplasty, surgical-site infections occurred in 63 of 1109 patients (5.7%) in the vancomyin group and in 42 of 1124 patients (3.7%) in the placebo group (relative risk, 1.52; 95% CI, 1.04 to 2.23). Among patients undergoing hip arthroplasty, surgical-site infections occurred in 28 of 920 patients (3.0%) in the vancomyin group and in 29 of 930 patients (3.1%) in the placebo group (relative risk, 0.98; 95% CI, 0.59 to 1.63). Adverse events occurred in 35 of 2010 patients (1.7%) in the vancomycin group and in 35 of 2030 patients (1.7%) in the placebo group, including hypersensitivity reactions in 24 of 2010 patients (1.2%) and 11 of 2030 patients (0.5%), respectively (relative risk, 2.20; 95% CI, 1.08 to 4.49), and acute kidney injury in 42 of 2010 patients (2.1%) and 74 of 2030 patients (3.6%), respectively (relative risk, 0.57; 95% CI, 0.39 to 0.83). CONCLUSIONS: The addition of vancomycin to cefazolin prophylaxis was not superior to placebo for the prevention of surgical-site infections in arthroplasty among patients without known MRSA colonization.

Objective This study evaluated whether a consumer codesigned leaflet about the common skin infection cellulitis would improve patient satisfaction. Methods A patient information leaflet was codesigned with consumers incorporating health literacy principles and attached to a new adult lower limb cellulitis management plan launched in three regional Victorian health services. Health service staff were educated to provide the leaflet during hospital care. Patients discharged with a diagnosis of cellulitis in an 8-month period were followed-up via telephone between 31 and 60 days after their discharge. Each patient was asked to provide feedback on the utility of the leaflet (if received) and their overall satisfaction with the information provided to them using a five-point scale (with scores of 4 or 5 considered to indicate satisfaction). Results In all, 81 of 127 (64%) patients (or carers) were contactable, consented to the study and answered the questions. Of these, 27% (n = 22) reported receiving, accepting and reading the leaflet. The proportion of patients who were satisfied with the information provided to them about cellulitis was 100% for those who received the leaflet, compared with 78% for those who did not receive the leaflet (95% confidence interval 4.8-34%; P = 0.02). Conclusion The provision of a consumer codesigned leaflet increased patient satisfaction with the information received about cellulitis. Real-world strategies to embed the delivery of such resources are required to ensure that more patients receive the benefit. What is known about the topic? There are known deficiencies in the information provided to patients about the common skin condition cellulitis. There is little published evaluation of strategies to address these knowledge deficiencies. What does this paper add? This study evaluated a simple strategy to address patient knowledge deficiencies on cellulitis. It highlights that pertinent information delivered in an accessible way can significantly increase patient satisfaction with the information provided to them. What are the implications for practitioners? These findings are a timely reminder for practitioners that even a simple intervention, such a providing a hard copy information leaflet, can improve patient satisfaction. A national repository of similar consumer codesigned materials would be valuable and could minimise existing duplication of effort in resource development across health sectors. Real-world strategies to embed the delivery of such resources is required to ensure that more patients receive the benefit.

BACKGROUND: Hospital-based contact tracing aims to limit spread of COVID-19 within healthcare facilities. In large outbreaks, this can stretch resources and workforce due to quarantine of uninfected staff. We analysed the performance of a manual contact tracing system for healthcare workers (HCW) at a multi-site healthcare facility in Melbourne, Australia, from June-September 2020, during an epidemic of COVID-19. METHODS: All HCW close contacts were quarantined for 14 days, and tested around day 11, if not already diagnosed with COVID-19. We examined the prevalence and timing of symptoms in cases detected during quarantine, described this group as proportions of all close contacts and of all cases, and used logistic regression to assess factors associated with infection. RESULTS: COVID-19 was diagnosed during quarantine in 52 furloughed HCWs, from 483 quarantine episodes (11%), accounting for 19% (52/270) of total HCW cases. In 361 exposures to a clear index case, odds of infection were higher after contact with an infectious patient compared to an infectious HCW (aOR: 4.69, 95% CI: 1.98-12.14). Contact with cases outside the workplace increased odds of infection compared to workplace contact only (aOR: 7.70, 95% CI: 2.63-23.05). We estimated 30%, 78% and 95% of symptomatic cases would develop symptoms by days 3, 7, and 11 of quarantine, respectively. CONCLUSION: In our setting, hospital-based contact tracing detected and contained a significant proportion of HCW cases, without excessive quarantine of uninfected staff. Effectiveness of contact tracing is determined by a range of dynamic factors, so system performance should be monitored in real-time.

Antimicrobial stewardship (AMS) in Australia is supported by a number of factors, including enabling national policies, sectoral clinical governance frameworks and surveillance programmes, clinician-led educational initiatives and health services research. A One Health research programme undertaken by the National Centre for Antimicrobial Stewardship (NCAS) in Australia has combined antimicrobial prescribing surveillance with qualitative research focused on developing antimicrobial use-related situational analyses and scoping AMS implementation options across healthcare settings, including metropolitan hospitals, regional and rural hospitals, aged care homes, general practice clinics and companion animal and agricultural veterinary practices. Qualitative research involving clinicians across these diverse settings in Australia has contributed to improved understanding of contextual factors that influence antimicrobial prescribing, and barriers and facilitators of AMS implementation. This body of research has been underpinned by a commitment to supplementing 'big data' on antimicrobial prescribing practices, where available, with knowledge of the sociocultural, technical, environmental and other factors that shape prescribing behaviours. NCAS provided a unique opportunity for exchange and cross-pollination across the human and animal health programme domains. It has facilitated synergistic approaches to AMS research and education, and implementation of resources and stewardship activities. The NCAS programme aimed to synergistically combine quantitative and qualitative approaches to AMS research. In this article, we describe the qualitative findings of the first 5 years.
RESUMO
OBJECTIVES: There have been efforts to promote timely antimicrobial administration for patients with sepsis, but the importance for other infections is uncertain. This study analysed whether time to first antimicrobial dose (TFAD) in patients with lower limb cellulitis influenced outcome measures such as acute length of stay (LOS) in hospital and 30-day hospital readmission rates for cellulitis. METHODS: Medical records of patients admitted with lower limb cellulitis or erysipelas over a 15-month period (1 May 2019 to 30 November 2019 and 1 March 2020 to 31 October 2020) were reviewed. Patients requiring intensive care unit (ICU) admission were excluded. The TFAD was the difference (in minutes) between the emergency department triage time and the time that the antimicrobial was first recorded as administered. Analysis included log-transformed linear regression (for LOS) and logistic regression (for 30-day readmission with cellulitis), controlling for confounders where possible. RESULTS: The study included 282 patients with lower limb cellulitis. The median TFAD was 177 min (interquartile range, 98-290 min). Linear regression suggested a weak association between TFAD and LOS (P = 0.05; adjusted R2 = 0.01), which was non-significant after adjusting for confounders (P = 0.18). There were too few patients readmitted within 30 days with cellulitis for meaningful analysis. CONCLUSION: After controlling for confounders, no association between increased TFAD and increased acute LOS was identified for patients with lower limb cellulitis who did not require ICU admission (i.e. without septic shock). Conclusions could not be made for 30-day readmission rates for cellulitis.

OBJECTIVES: To design and evaluate 3D-printed nasal swabs for collection of samples for SARS-CoV-2 testing. DESIGN: An iterative design process was employed. Laboratory evaluation included in vitro assessment of mock nasopharyngeal samples spiked with two different concentrations of gamma-irradiated SARS-CoV-2. A prospective clinical study compared SARS-CoV-2 and human cellular material recovery by 3D-printed swabs and standard nasopharyngeal swabs. SETTING, PARTICIPANTS: Royal Melbourne Hospital, May 2020. Participants in the clinical evaluation were 50 hospital staff members attending a COVID-19 screening clinic and two inpatients with laboratory-confirmed COVID-19. INTERVENTION: In the clinical evaluation, a flocked nasopharyngeal swab sample was collected with the Copan ESwab and a mid-nasal sample from the other nostril was collected with the 3D-printed swab. RESULTS: In the laboratory evaluation, qualitative agreement with regard to SARS-CoV-2 detection in mock samples collected with 3D-printed swabs and two standard swabs was complete. In the clinical evaluation, qualitative agreement with regard to RNase P detection (a surrogate measure of adequate collection of human cellular material) in samples collected from 50 hospital staff members with standard and 3D-printed swabs was complete. Qualitative agreement with regard to SARS-CoV-2 detection in three pairs of 3D-printed mid-nasal and standard swab samples from two inpatients with laboratory-confirmed SARS-CoV-2 was also complete. CONCLUSIONS: Using 3D-printed swabs to collect nasal samples for SARS-CoV-2 testing is feasible, acceptable to patients and health carers, and convenient.

The rapid spread of severe acute respiratory syndrome coronavirus 2 led to the declaration of a global pandemic within 3 months of its emergence. The majority of patients presenting with coronavirus disease 2019 (COVID-19) experience a mild illness that can usually be managed in the community. Patients require careful monitoring and early referral to hospital if any signs of clinical deterioration occur. Increased age and the presence of comorbidities are associated with more severe disease and poorer outcomes. Treatment for COVID-19 is currently predominantly supportive care, focused on appropriate management of respiratory dysfunction. Clinical evidence is emerging for some specific therapies (including antiviral and immune-modulating agents). Investigational therapies for COVID-19 should be used in the context of approved randomised controlled trials. Australian clinicians need to be able to recognise, diagnose, manage and appropriately refer patients affected by COVID-19, with thousands of cases likely to present over the coming years.

Objective The aim of this study was to explore the features of sustainable antimicrobial stewardship (AMS) programs in Australian rural hospitals and develop recommendations on incorporating these features into rural hospitals' AMS programs. Methods Lead AMS clinicians with knowledge of at least one AMS program sustained for >2 years in a health service in rural Australia were recruited to the study. A series of interviews was conducted and the transcripts analysed thematically using a framework method. Results Fifteen participants from various professional disciplines were interviewed. Key features that positively affected the sustainability of AMS programs in rural hospitals included a hospital executive who provided strong governance and accountability, dedicated resources, passionate local champions, area-wide arrangements and adaptability to engage in new partnerships. Challenges to building AMS programs with these features were identified, particularly in engaging hospital executive to allocate AMS resources, managing the burn out of passionate champions and formalising network arrangements. Conclusions Strategies to increase the sustainability of AMS programs in rural hospitals include using accreditation as a mechanism to drive direct resource allocation, explicit staffing recommendations for rural hospitals, greater support to develop formal network arrangements and a framework for integrated AMS programs across primary, aged and acute care. What is known about the topic? AMS programs facilitate the responsible use of antimicrobials. Implementation challenges have been identified for rural hospitals, but the sustainability of AMS programs has not been explored. What does this paper add? Factors that positively affected the sustainability of AMS programs in rural hospitals were a hospital executive that provided strong governance and accountability, dedicated resources, network or area-wide arrangements and adaptability. Challenges to building AMS programs with these features were identified. What are the implications for practitioners? Recommended actions to boost the sustainability of AMS programs in rural hospitals are required. These include using accreditation as a mechanism to drive direct resource allocation, explicit staffing recommendations for rural hospitals, greater support to develop network arrangements and support to create integrated AMS programs across acute, aged and primary care.

BACKGROUND: Antimicrobial stewardship programmes are important in driving safety and quality of antimicrobial prescribing. The National Antimicrobial Prescribing Survey (NAPS) is a point-prevalence audit of inpatient antimicrobial prescribing in Australian hospitals. OBJECTIVES: To design and adapt the NAPS tool for use in the outpatient parenteral antimicrobial therapy (OPAT) and hospital-in-the-home (HITH) setting. METHODS: An inter-disciplinary working group with expertise in OPAT and HITH services was established to adapt the NAPS template for use in the OPAT setting-called HITH-NAPS. This was initially trialled in 5 HITH services, subsequently adapted following participant feedback, then offered nationally to 50 services in 2017. RESULTS: There were 1154 prescriptions for 715 patients audited via the HITH-NAPS. The most common antimicrobials prescribed were cefazolin (22%), flucloxacillin (12%), piperacillin/tazobactam (10%) and ceftriaxone (10%). The most common infections treated were cellulitis (30%) and respiratory tract infections (14%). Eighty-seven percent of prescriptions were assessed as appropriate, 11% inappropriate and 2% not assessable. Prolonged durations of antimicrobials and unnecessarily broad-spectrum antibiotics were used in 9% of prescriptions. CONCLUSIONS: The HITH-NAPS pilot project revealed that auditing of this type is feasible in HITH. It showed that antibiotic use in these HITH services was generally appropriate, but there are some areas for improvement. A national OPAT/HITH-NAPS can facilitate benchmarking between services, identify potentially inappropriate prescribing and help guide quality improvement.
RESUMO
Many regional and remote hospitals (RRHs) do not have the specialist services that usually support antimicrobial stewardship (AMS) programmes in major city hospitals. It is not known if this is associated with higher rates of inappropriate antimicrobial prescribing. The aim of this study was to identify similarities and differences in antimicrobial prescribing patterns between major city hospitals and RRHs in Australia. The Australian Hospital National Antimicrobial Prescribing Survey (H-NAPS) datasets from 2014, 2015 and 2016 (totalling 47,876 antimicrobial prescriptions) were analysed. The antimicrobial prescribed, indications for use, documentation of indication, recording of a review date and assessment of the appropriateness of prescribing were evaluated. Overall, inappropriate prescribing of antimicrobials was higher in RRHs than in major city hospitals (24.0% vs. 22.1%; P<0.001). Compared with major city hospitals, inappropriate prescribing of ceftriaxone was higher in RRHs (33.9% vs. 27.6%; P<0.001), as was inappropriate prescribing for cellulitis (25.7% vs. 19.0%; P≤0.001). A higher rate of inappropriate prescribing was noted for some high-risk infections in RRHs compared with major city hospitals, including Gram-positive bacteraemia with sepsis (12.6% vs. 6.5%; P=0.004), empiric therapy for sepsis (26.0% vs. 12.0%; P<0.001) and endocarditis (8.2% vs. 2.7%; P=0.02). To the authors' knowledge, this is the largest study to date comparing antimicrobial prescribing of RRHs with major city hospitals. A key finding was that antimicrobial prescribing was more frequently inappropriate for some high-risk infections treated in RRHs. Targeted strategies that support appropriate antimicrobial prescribing in RRHs are required.

INTRODUCTION: Antimicrobial resistance (AMR) has been recognised as an urgent health priority, both nationally and internationally. Australian hospitals are required to have an antimicrobial stewardship (AMS) program, yet the necessary resources may not be available in regional, rural or remote hospitals. This review will describe models for AMS programs that have been introduced in regional, rural or remote hospitals internationally and showcase achievements and key considerations that may guide Australian hospitals in establishing or sustaining AMS programs in the regional, rural or remote hospital setting. METHODS: A narrative review was undertaken based on literature retrieved from searches in Ovid Medline, Scopus, Web of Science and the grey literature. 'Cited' and 'cited by' searches were undertaken to identify additional articles. Articles were included if they described an AMS program in the regional, rural or remote hospital setting (defined as a bed size less than 300 and located in a non-metropolitan setting). RESULTS: Eighteen articles were selected for inclusion. The AMS initiatives described were categorised into models designed to address two different challenges relating to AMS program delivery in regional, rural and remote hospitals. This included models to enable regional, rural and remote hospital staff to manage AMS programs in the absence of on-site infectious diseases (ID) trained experts. Non-ID doctor-led, pharmacist-led and externally led initiatives were identified. Lack of pharmacist resources was recognised as a core barrier to the further development of a pharmacist-led model. The second challenge was access to timely off-site expert ID clinical advice when required. Examples where this had been overcome included models utilising visiting ID specialists, telehealth and hospital network structures. Formalisation of such arrangements is important to clarify the accountabilities of all parties and enhance the quality of the service. Information technology was identified as a facilitator to a number of these models. The variance in availability of information technology between hospitals and cost limits the adoption of uniform programs to support AMS. CONCLUSION: Despite known barriers, regional, rural and remote hospitals have implemented AMS programs. The examples highlighted show that difficulty recruiting ID specialists should not inhibit AMS programs in regional, rural and remote hospitals, as much of the day-to-day work of AMS can be done by non-experts. Capacity building and the strengthening of networks are core features of these programs. Descriptions of how Australian regional, rural and remote hospitals have structured and supported their AMS programs would add to the existing body of knowledge sourced from international examples. Research into AMS programs predominantly led by GPs and nursing staff will provide further possible models for regional, rural and remote hospitals.

BACKGROUND: Antimicrobial prophylaxis at the time of urinary catheter insertion and removal is commonly administered in patients undergoing joint arthroplasty, despite the lack of evidence to support this practice. The rationale is the theoretical risk of prosthetic joint infection arising from bacterial seeding from the urinary tract at the time of catheterization. In an era of antimicrobial stewardship, further assessment is warranted. METHODS: This study aimed to investigate the incidence of catheter-associated (CA) bacteriuria and bacteraemia in patients undergoing total joint arthroplasty and to assess the antimicrobial susceptibility of any isolated microorganisms. This prospective observational study undertaken over a 6-month period (May to October 2014) included 99 patients undergoing elective primary hip and knee arthroplasty at St Vincent's Hospital, Melbourne. Urine specimens were collected at insertion and removal of urinary catheters along with blood cultures upon urinary catheter removal. RESULTS: Overall 98% of the cohort received catheter antimicrobial prophylaxis for urinary catheter insertion and removal; the majority of patients received gentamicin (94%). Bacteriuria on catheter insertion had an incidence of 4.4%. The incidence of CA bacteriuria was 1.3%. All cultured organisms were sensitive to commonly used antibiotics including cephazolin. There were no cases of bacteraemia with urinary catheter removal. Increasing age, American Society of Anesthesiologists status and female gender were associated with the development of bacteriuria. CONCLUSION: The incidence of CA bacteriuria and bacteraemia with antimicrobial prophylaxis is low. This study provokes discussion about the requirement of catheter prophylaxis in this surgical context and the utility of preoperative urine screening.

OBJECTIVE: To explore organisational factors and barriers contributing to limited uptake of antimicrobial stewardship (AMS) in Australian private hospitals and to determine solutions for AMS implementation. METHODS: A qualitative study using a series of focus group discussions was conducted in a large private hospital making use of a semistructured interview guide to facilitate discussion among clinical and non-clinical stakeholders. A thematic analysis using five sequential components that mapped and interpreted emergent themes surrounding AMS implementation was undertaken by a multidisciplinary team of researchers. RESULTS: Analysis revealed that autonomy of consultant specialists was perceived as being of greater significance in private hospitals compared with public hospitals. Use of an expert team providing antimicrobial prescribing advice and education without intruding on existing patient-specialist relationships was proposed by participants as an acceptable method of introducing AMS in private hospitals. There was more opportunity for nursing and pharmacist involvement, as well as empowering patients. Opportunities were identified for the hospital executive to market an AMS service as a feature that promoted excellence in patient care. CONCLUSIONS: Provision of advice from experts, championing by clinical leaders, marketing by hospital executives and involving nurses, pharmacists and patients should be considered during implementation of AMS in private hospitals.

OBJECTIVE: To explore organisational workflow and workplace culture influencing antibiotic prescribing behaviour from the perspective of key health care providers working in residential aged care facilities (RACFs). DESIGN, SETTING AND PARTICIPANTS: Qualitative approach using semistructured interviews, focus groups and onsite observation between 8 January 2013 and 2 July 2013. Nursing staff, general practitioners and pharmacists servicing residents at 12 high-level care RACFs in Victoria were recruited. MAIN OUTCOME MEASURES: Emergent themes on antibiotic prescribing practices in RACFs. RESULTS: Sixty-one participants (40 nurses, 15 GPs and six pharmacists) participated. Factors influencing antibiotic prescribing practice have been divided into workflow-related and culture-related factors. Five major themes emerged among workflow-related factors: logistical challenges with provision of medical care, pharmacy support, nurse-driven infection management, institutional policies and guidelines, and external expertise and diagnostic facilities. Lack of onsite medical and pharmacy staff led to nursing staff adopting significant roles in infection management. However, numerous barriers hindered optimal antibiotic prescribing, especially inexperienced staff, lack of training of nurses in antibiotic use and lack of institutional infection management guidelines. With regard to culture-related factors, pressure from family to prescribe and institutional use of advance care directives were identified as important influences on antibiotic prescribing practices. CONCLUSIONS: Workflow- and culture-related barriers to optimal antibiotic prescribing were identified. This study has provided important insights to guide antimicrobial stewardship interventions in the RACF setting, particularly highlighting the role of nurses.
