Preparing for the Next Pandemic: An After-Action Review of Infection Prevention and Control Audit Strategies Within Airport and Hotel Quarantine Program.

BACKGROUND: Effective infection prevention and control (IPAC) practices within the New South Wales (NSW) Airport Operations and Hotel Quarantine Program (Quarantine Program) were required to mitigate the risk of COVID-19 being transmitted to staff, other guests, contractors, and the community. METHOD: The Quarantine Program relied on complex logistical arrangements and an end-to-end process that included all steps from the time travelers boarded the returning flight until completion of the quarantine period. This required compliance with relevant IPAC standards historically reserved for health care and the implementation of a quality assurance audit framework. RESULTS: The Clinical Excellence Commission (CEC) as the NSW Health Pillar for quality and safety and the lead in IPAC provided training and resources coupled with an IPAC quality audit framework after program commencement. CONCLUSION: This approach ensured a clear governance structure and a regular review process to minimize risk and support continuous improvement within the program.

Prevalence of antibiotic allergy labels and their consequences in people presenting to a teaching hospital Emergency Department; a retrospective chart review.

BACKGROUND: Antibiotic allergy labels have a direct impact on individual patient care and on the consumption of broad-spectrum antibiotics. OBJECTIVE: Our aim was to establish the prevalence of antibiotic allergies and to determine whether patients with documented antibiotic allergy labels received guideline concordant antimicrobial therapy. Additionally we wanted to evaluate the quality of allergy documentation in the medical record. METHODS: Prospective audit of all patients presenting to the Emergency Department of an adult teaching hospital in Sydney over a 4 month period. Documented allergy labels, diagnoses, antibiotic administration and outcomes were recorded. Appropriateness of antibiotic choice was based on the Australian National Antimicrobial Prescribing Survey. RESULTS: 9.9% of presentations had at least one antibiotic allergy recorded. Significantly more women than men had antibiotic allergies documented. One third of patients with documented antibiotic allergies were prescibed inappropriate antibiotic therapy and some had significant adverse events. CONCLUSIONS: The documentation of antibiotic allergy labels and choice of antibiotic treatment can be significantly improved. Strategies to safely de-label people with documented allergies who are not truly allergic need to be implemented.

Impact of Rapid Molecular Diagnostic Testing of Respiratory Viruses on Outcomes of Adults Hospitalized with Respiratory Illness: a Multicenter Quasi-experimental Study.

A standard multiplex PCR offers comprehensive testing for respiratory viruses. However, it has traditionally been performed in a referral laboratory with a lengthy turnaround time, which can reduce patient flow through the hospital. We aimed to determine whether the introduction of a rapid PCR, but with limited targets (Cepheid Xpert Flu/RSV XC), was associated with improved outcomes for adults hospitalized with respiratory illness. A controlled quasi-experimental study was conducted across three hospitals in New South Wales, Australia. Intervention groups received standard multiplex PCR during the preimplementation, July to December 2016 (n = 953), and rapid PCR during the postimplementation, July to December 2017 (n = 1,209). Control groups (preimplementation, n = 937, and postimplementation, n = 1,102) were randomly selected from adults hospitalized with respiratory illness during the same periods. The outcomes were hospital length of stay (LOS) and microbiology test utilization (blood culture, urine culture, sputum culture, and respiratory bacterial and virus serologies). The introduction of rapid PCR was associated with a nonsignificant 8.9-h reduction in median LOS (95% confidence interval [CI], -21.5 h to 3.7 h; P = 0.17) for all patients and a significant 21.5-h reduction in median LOS (95% CI, -36.8 h to -6.2 h; P < 0.01) among patients with positive test results in an adjusted difference-in-differences analysis. For patients receiving test results before disposition, rapid PCR use was associated with a significant reduction in LOS, irrespective of test results. Compared with standard PCR testing, rapid PCR use was significantly associated with fewer blood culture (adjusted odds ratio [aOR], 0.67; 95% CI, 0.5 to 0.82; P < 0.001), sputum culture (aOR, 0.56; 95% CI, 0.47 to 0.68, P < 0.001), bacterial serology (aOR, 0.44; 95% CI, 0.35 to 0.55, P < 0.001) and viral serology (aOR, 0.42; 95% CI, 0.33 to 0.53, P < 0.001) tests, but not with fewer urine culture tests (aOR, 0.94; 95% CI, 0.78 to 1.12, P = 0.48). Rapid PCR testing of adults hospitalized with respiratory illnesses can deliver benefits to patients and reduce resource utilization. Future research should consider a formal economic analysis and assess its potential impacts on clinical decision making.

The impact of rapid molecular diagnostic testing for respiratory viruses on outcomes for emergency department patients.

OBJECTIVE: To determine whether rapid polymerase chain reaction (PCR) testing for influenza and respiratory syncytial viruses (RSV) in emergency departments (EDs) is associated with better patient and laboratory outcomes than standard multiplex PCR testing. DESIGN, SETTING: A before-and-after study in four metropolitan EDs in New South Wales. PARTICIPANTS: 1491 consecutive patients tested by standard multiplex PCR during July-December 2016, and 2250 tested by rapid PCR during July-December 2017. MAIN OUTCOME MEASURES: Hospital admissions; ED length of stay (LOS); test turnaround time; patient receiving test result before leaving the ED; ordering of other laboratory tests. RESULTS: Compared with those tested by standard PCR, fewer patients tested by rapid PCR were admitted to hospital (73.3% v 77.7%; P < 0.001) and more received their test results before leaving the ED (67.4% v 1.3%; P < 0.001); the median test turnaround time was also shorter (2.4 h [IQR, 1.6-3.9 h] v 26.7 h [IQR, 21.2-37.8 h]). The proportion of patients admitted to hospital was also lower in the rapid PCR group for both children under 18 (50.6% v 66.6%; P < 0.001) and patients over 60 years of age (84.3% v 91.8%; P < 0.001). Significantly fewer blood culture, blood gas, sputum culture, and respiratory bacterial and viral serology tests were ordered for patients tested by rapid PCR. ED LOS was similar for the rapid (7.4 h; IQR, 5.0-12.9 h) and standard PCR groups (6.5 h; IQR, 4.2-11.9 h; P = 0.27). CONCLUSION: Rapid PCR testing of ED patients for influenza virus and RSV was associated with better outcomes on a range of indicators, suggesting benefits for patients and the health care system. A formal cost-benefit analysis should be undertaken.

Probiotics [LGG-BB12 or RC14-GR1] versus placebo as prophylaxis for urinary tract infection in persons with spinal cord injury [ProSCIUTTU]: a randomised controlled trial.

STUDY DESIGN: Randomised double-blind factorial-design placebo-controlled trial. OBJECTIVE: Urinary tract infections (UTIs) are common in people with spinal cord injury (SCI). UTIs are increasingly difficult to treat due to emergence of multi-resistant organisms. Probiotics are efficacious in preventing UTIs in post-menopausal women. We aimed to determine whether probiotic therapy with Lactobacillus reuteri RC-14+Lactobacillus GR-1 (RC14-GR1) and/or Lactobacillus rhamnosus GG+Bifidobacterium BB-12 (LGG-BB12) are effective in preventing UTI in people with SCI. SETTING: Spinal units in New South Wales, Australia with their rural affiliations. METHODS: We recruited 207 eligible participants with SCI and stable neurogenic bladder management. They were randomised to one of four arms: RC14-GR1+LGG-BB12, RC14-GR1+placebo, LGG-BB12+ placebo or double placebos for 6 months. Randomisation was stratified by bladder management type and inpatient or outpatient status. The primary outcome was time to occurrence of symptomatic UTI. RESULTS: Analysis was based on intention to treat. Participants randomised to RC14-GR1 had a similar risk of UTI as those not on RC14-GR1 (HR 0.67; 95% CI: 0.39-1.18; P = 0.17) after allowing for pre-specified covariates. Participants randomised to LGG-BB12 also had a similar risk of UTI as those not on LGG-BB12 (HR 1.29; 95% CI: 0.74-2.25; P = 0.37). Multivariable post hoc survival analysis for RC14-GR1 only vs. the other three groups showed a potential protective effect (HR 0.46; 95% CI: 0.21-0.99; P = 0.03), but this result would need to be confirmed before clinical application. CONCLUSION: In this RCT, there was no effect of RC14-GR1 or LGG-BB12 in preventing UTI in people with SCI.

Cluster of invasive Mycobacteria chimaera infections following cardiac surgery demonstrating novel clinical features and risks of aortic valve replacement.

There is a global outbreak of infections due to Mycobacterium chimaera associated with cardiac surgery. The most serious infections involve prosthetic material implantation, and all have followed surgical procedures involving cardiopulmonary bypass. We describe a cluster of four cases following cardiac surgery at a tertiary referral centre in Sydney, Australia. We report novel clinical findings, including haemolysis and kidney rupture possibly related to immune reconstitution inflammatory syndrome. The positive effect of corticosteroids on haemodynamic function in two cases and the failure of currently recommended antimicrobial therapy to sterilise prosthetic valve material in the absence of surgery despite months of treatment are also critically examined. Positron emission tomography was positive in two cases despite normal transoesophageal echocardiograms. The proportion of cases with M. chimaera infection after aortic valve replacement (4/890, 0.45%; 95% confidence interval 0.18-1.15%) was significantly higher than after all other cardiothoracic surgical procedures (0/2433, 0%; 95% confidence interval 0-0.16%).

Outcomes of multisite antimicrobial stewardship programme implementation with a shared clinical decision support system.

Background: Studies evaluating antimicrobial stewardship programmes (ASPs) supported by computerized clinical decision support systems (CDSSs) have predominantly been conducted in single site metropolitan hospitals. Objectives: To examine outcomes of multisite ASP implementation supported by a centrally deployed CDSS. Methods: An interrupted time series study was conducted across five hospitals in New South Wales, Australia, from 2010 to 2014. Outcomes analysed were: effect of the intervention on targeted antimicrobial use, antimicrobial costs and healthcare-associated Clostridium difficile infection (HCA-CDI) rates. Infection-related length of stay (LOS) and standardized mortality ratios (SMRs) were also assessed. Results: Post-intervention, antimicrobials targeted for increased use rose from 223 to 293 defined daily doses (DDDs)/1000 occupied bed days (OBDs)/month (+32%, P < 0.01). Conversely, antimicrobials targeted for decreased use fell from 254 to 196 DDDs/1000 OBDs/month (-23%; P < 0.01). These effects diminished over time. Antimicrobial costs decreased initially (-AUD$64551/month; P < 0.01), then increased (+AUD$7273/month; P < 0.01). HCA-CDI rates decreased post-intervention (-0.2 cases/10 000 OBDs/month; P < 0.01). Proportional LOS reductions for key infections (respiratory from 4.8 to 4.3 days, P < 0.01; septicaemia 6.8 to 6.1 days, P < 0.01) were similar to background LOS reductions (2.1 to 1.9 days). Similarly, infection-related SMRs (observed/expected deaths) decreased (respiratory from 1.1 to 0.75; septicaemia 1.25 to 0.8; background rate 1.19 to 0.90. Conclusions: Implementation of a collaborative multisite ASP supported by a centrally deployed CDSS was associated with changes in targeted antimicrobial use, decreased antimicrobial costs, decreased HCA-CDI rates, and no observable increase in LOS or mortality. Ongoing targeted interventions are suggested to promote sustainability.

Probiotics for preventing urinary tract infection in people with neuropathic bladder.

BACKGROUND: Neuropathic or neurogenic bladder describes a process of dysfunctional voiding as the result of injury in the brain, spinal cord or nerves innervating the bladder. People with neuropathic bladder, such as from spinal cord injury (SCI), are at significant risk of morbidity from urinary tract infections (UTI). Effective methods to prevent UTI in people with SCI have been sought for many years. Probiotics (micro-organisms that exert beneficial health effects in the host) have been recommended for bacterial interference of the urological tract to reduce colonisation by uropathogen and to manage the dual problems of infection and antibiotic resistance. OBJECTIVES: This review looked at the benefits and harms of probiotics in preventing symptomatic UTI in people with neuropathic bladder compared with placebo, no therapy, or non-antibiotic prophylaxis (cranberry juice, methenamine hippurate, topical oestrogen). SEARCH METHODS: We searched the Cochrane Kidney and Transplant Specialised Register up to 10 March 2017 through contact with the Information Specialist using search terms relevant to this review. Studies in the Specialised Register are identified through searches of CENTRAL, MEDLINE, and EMBASE, conference proceedings, the International Clinical Trials Register (ICTRP) Search Portal, and ClinicalTrials.gov. SELECTION CRITERIA: All randomised controlled trials (RCTs), quasi-RCTs and cross-over RCTs looking at the use of probiotics for the prophylaxis of UTI in people with neuropathic bladders was considered for inclusion. Men, women and children of all ages with neuropathic bladders from neurological injury such as suprapontine, supra sacral and sacral aetiologies was included. All bladder management types, including reflex voiding, time voiding, indwelling and intermittent catheterization were eligible for this review.Studies comparing probiotics to placebo, no treatment or other non-antibiotic prophylaxis was included. Studies comparing probiotics with antibiotics or in combination with antibiotics were excluded. DATA COLLECTION AND ANALYSIS: Summary estimates of effect were obtained using a random-effects model, and results were expressed as risk ratios (RR) and their 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) or standardised mean difference (SMD) and 95% CI were planned for continuous outcomes. MAIN RESULTS: This review includes a total of three studies (one cross-over and two parallel RCTs) which involved 110 participants. All three studies looked at intravesical instillation of a low virulent Escherichia coli (E. coli) strain in reducing the risk of symptomatic UTI in participants with neuropathic bladder, predominantly from SCI. Two studies used the E. coli 83972 strain and one study used the E. coli HU2117 strain.We did not find any RCTs involving other probiotics or other routes of administration for preventing UTI in people with neuropathic bladder.There was consistency in definition of symptomatic UTI in all three studies. Symptoms that all studies considered were relevant to diagnose UTI were adequately defined. All three studies defined microbiological diagnosis of symptomatic UTI.Asymptomatic bacteriuria was not considered an outcome measure in any of the included studies; however it was defined in two studies to establish successful inoculation.It is uncertain if the risk of symptomatic UTI is reduced with bladder inoculation using E. coli because the certainty of the evidence is very low (3 studies, 110 participants: RR 0.32, 95% CI 0.08 to 1.19; I2 = 82%).Two studies reported adverse events. One study reported one episode of autonomic dysreflexia. One study reported three symptomatic UTI occurring in two patients, and two studies mentioned the absence of septicaemia and pyelonephritis. Intravesical instillation was reported as "generally safe". One study reported high attrition rates in participants due to the need to adhere to strict instillation protocols.The overall quality of the studies was poor. All three studies had high risk of attrition bias due to failure of an intention-to-treat analysis which undermines the randomisation process and weakened the results of the studies. All three studies also had high risk of reporting bias. AUTHORS' CONCLUSIONS: In this review, there were no studies identified addressing oral probiotics in preventing UTI in people with neuropathic bladder. It is uncertain if the risk of symptomatic UTI is reduced in people with neuropathic bladders via intravesical instillation of non-pathogenic E. coli as data were derived from small studies with high risk of bias.Although very minimal levels of harm was reported with this procedure, due to variable success rates, the need for strict adherence to instillation protocols together with high attrition rates in these studies, it is doubtful bladder instillation will be a widely accepted intervention in its current form.It is recommended that further appropriately powered RCTs with more robust methodological reporting be carried out.

Outbreak of respiratory syncytial virus (RSV) infection in immunocompromised adults on a hematology ward.

We describe an outbreak of respiratory syncytial virus (RSV) infection on a hematology ward without allogeneic stem cell transplant patients. Twelve patients and one staff member infected with RSV were identified from the laboratory database. Five patients had lower respiratory tract infection, seven had upper respiratory tract infection, one was asymptomatic, and there were two (15.4%) deaths. Most patients had overlapping periods of potential infectiousness on the ward. Sequencing was possible on eight specimens and five of these had identical sequences. Results were consistent with transmission occurring both on the ward and by introduction of RSV from the community. J. Med. Virol. 88:1827-1831, 2016. © 2016 Wiley Periodicals, Inc.

Probiotics [LGG-BB12 or RC14-GR1] versus placebo as prophylaxis for urinary tract infection in persons with spinal cord injury [ProSCIUTTU]: a study protocol for a randomised controlled trial.

BACKGROUND: Urinary tract infections [UTIs] are very common in people with Spinal Cord Injury [SCI]. UTIs are increasingly difficult and expensive to treat as the organisms that cause them become more antibiotic resistant. Among the SCI population, there is a high rate of multi-resistant organism [MRO] colonisation. Non-antibiotic prevention strategies are needed to prevent UTI without increasing resistance. Probiotics have been reported to be beneficial in preventing UTIs in post-menopausal women in several in vivo and in vitro studies. The main aim of this study is to determine whether probiotic therapy with combinations of Lactobacillus reuteri RC-14 + Lactobacillus rhamnosus GR-1 [RC14-GR1] and/or Lactobacillus rhamnosus GG + Bifidobacterium BB-12 [LGG-BB12] are effective in preventing UTI in people with SCI compared to placebo. METHOD: This is a multi-site randomised double-blind double-dummy placebo-controlled factorial design study conducted in New South Wales, Australia. All participants have a neurogenic bladder as a result of spinal injury. Recruitment started in April 2011. Participants are randomised to one of four arms, designed for factorial analysis of LGG-BB12 and/or RC14-GR1 v Placebo. This involves 24 weeks of daily oral treatment with RC14-GR1 + LGG-BB12, RC14-GR1 + placebo, LGG-BB12 + placebo or two placebo capsules. Randomisation is stratified by bladder management type and inpatient status. Participants are assessed at baseline, three months and six months for Short Form Health Survey [SF-36], microbiological swabs of rectum, nose and groin; urine culture and urinary catheters for subjects with indwelling catheters. A bowel questionnaire is administered at baseline and three months to assess effect of probiotics on bowel function. The primary outcome is time from randomisation to occurrence of symptomatic UTI. The secondary outcomes are change of MRO status and bowel function, quality of life and cost-effectiveness of probiotics in persons with SCI. The primary outcome will be analysed using survival analysis of factorial groups, with Cox regression modelling to test the effect of each treatment while allowing for the other, assuming no interaction effect. Hazard ratios and Kaplan-Meier survival curves will be used to summarise results. DISCUSSION: If these probiotics are shown to be effective in preventing UTI and MRO colonisation, they would be a very attractive alternative for UTI prophylaxis and for combating the increasing rate of antibiotic resistance after SCI.

Anncaliia algerae microsporidial myositis.

The insect microsporidian Anncaliia algerae was first described in 2004 as a cause of fatal myositis in an immunosuppressed person from Pennsylvania, USA. Two cases were subsequently reported, and we detail 2 additional cases, including the only nonfatal case. We reviewed all 5 case histories with respect to clinical characteristics, diagnosis, and management and summarized organism life cycle and epidemiology. Before infection, all case-patients were using immunosuppressive medications for rheumatoid arthritis or solid-organ transplantation. Four of the 5 case-patients were from Australia. All diagnoses were confirmed by skeletal muscle biopsy; however, peripheral nerves and other tissues may be infected. The surviving patient received albendazole and had a reduction of immunosuppressive medications and measures to prevent complications. Although insects are the natural hosts for A. algerae, human contact with water contaminated by spores may be a mode of transmission. A. algerae has emerged as a cause of myositis, particularly in coastal Australia.

Evaluation of health worker acceptance and tolerance of respirators in clinical practice-An Australian perspective.

BACKGROUND: One of the main infection prevention and control measures introduced during the COVID-19 pandemic was the focused application of respiratory protection to ensure health worker safety and the effective use of personal protective equipment. However, user acceptance of these strategies is paramount in sustainable compliance. This study explores various aspects of respirator use and provides recommendations to improve and maximize health worker safety. The aim of this study was to understand the relationship between respirator (P2/N95) comfort and user experience toward respiratory protection. The aim of this study was to understand the relationship between respirator (P2/N95) comfort and user experience toward respiratory protection. METHODS: The nonexperimental cross-sectional design study was conducted in New South Wales, Australia between November and December 2022 using an anonymous self-administered online questionnaire in Microsoft Forms. RESULTS: Of 2,514 respondents, 65% reported to have used a respirator every working day with only a few using a respirator once weekly or less (9%). Almost all respondents had completed at least one quantitative fit test (96%) prior to the survey. Fifty-nine percent reported to have experienced discomfort from wearing a respirator and the most reported adverse effect was difficulty communicating (64%), followed by skin irritation or acne (62%) and headache (56%). CONCLUSIONS: Despite somewhat less favorable ratings on comfort and communication, health workers are in favor of respiratory protection. However, a focus on tolerance of respirators and strategies to address adverse effects from prolonged respirator use must be considered when implementing policies and procedures. Moreover, resources must be allocated to improve the design, breathability, and sustainability of a respirator along with education and training on how to use respiratory protection safely and effectively.

Implementation of a successful infection prevention and control governance structure and capacity building strategies during COVID-19 pandemic - A brief report.

An analysis of the Clinical Excellence Commissions response to COVID-19 prevention and protection measures identified the need to build on the existing governance process to achieve a more structured and methodical approach. The infection prevention and control measures and strategies implemented within health and nonhealth care, proved to be effective and sustainable with the ability to build additional clinician capacity even during an ongoing pandemic.

Lifting the curtains of silence: Patient perceptions towards needs and responsibilities in contributing to the prevention of healthcare-associated infections and antimicrobial resistance.

BACKGROUND: Beyond the use of policy and system-focused approaches, it has been established globally that patients can play a role in enhancing the health care landscape. However, efforts to meaningfully translate patient engagement strategies that promote participation by hospitalized patients in relevant infection prevention and antimicrobial stewardship activities have not yet been realized. This study mapped the key factors acting as barriers and facilitators of patient engagement using a theoretical framework to identify potential new approaches to promote engagement. METHODS: Semistructured interviews were conducted with 36 patients from 3 major hospitals in Sydney, Australia, in 2019. Transcripts were inductively analyzed, with the resulting themes categorized into the components of the Capability-Opportunity-Motivation-Behavior model. RESULTS: The themes regarding barriers to patient engagement with relevant infection prevention and antimicrobial stewardship activities were: (1) Capability: misunderstanding and knowledge gaps about antimicrobial resistance; (2) Opportunity: strong family/patient support networks and good relationships with nursing staff provide an opportunity to support engagement; (3) Motivation: those who have some level of understanding or experience see the benefit and are most likely to engage actively. CONCLUSIONS: Assuming patients are inclined to participate in efforts, a logical starting point would be to build awareness amongst patients and providers; however, education will not suffice. There needs to be a system and policy shift to ensure that patient engagement is recognized as a worthy endeavor.

Antimicrobial stewardship in primary health care programs in humanitarian settings: the time to act is now.

Fragile and conflict-affected settings bear a disproportionate burden of antimicrobial resistance, due to the compounding effects of weak health policies, disrupted medical supply chains, and lack of knowledge and awareness about antibiotic stewardship both among health care providers and health service users. Until now, humanitarian organizations intervening in these contexts have confronted the threat of complex multidrug resistant infections mainly in their surgical projects at the secondary and tertiary levels of care, but there has been limited focus on ensuring the implementation of adequate antimicrobial stewardship in primary health care, which is known to be setting where the highest proportion of antibiotics are prescribed. In this paper, we present the experience of two humanitarian organizations, Médecins sans Frontières and the International Committee of the Red Cross, in responding to antimicrobial resistance in their medical interventions, and we draw from their experience to formulate practical recommendations to include antimicrobial stewardship among the standards of primary health care service delivery in conflict settings. We believe that expanding the focus of humanitarian interventions in unstable and fragile contexts to include antimicrobial stewardship in primary care will strengthen the global response to antimicrobial resistance and will decrease its burden where it is posing the highest toll in terms of mortality.

Retrospective analysis of fungemia among children in Anka General Hospital, Nigeria, from October 2018 to November 2021: a case series.

Yeast-related bloodstream infections (BSIs) in pediatric patients are associated with severe acute malnutrition (SAM), hematological/oncological malignancies and admission to an intensive care unit. These infections are rarely described from low- and middle-income countries. We describe a case series of pediatric patients diagnosed with severe sepsis and yeast isolated from their blood culture in a conflict-affected area of Nigeria from October 2018 to November 2021. We identified 20 patients with yeast BSIs, among whom 17 were also diagnosed with SAM. We recommend the inclusion of antifungal treatment for empiric treatment guidelines for children with SAM and severe sepsis in similar settings.

Implementation of a respiratory protection program within healthcare facilities during the COVID-19 pandemic- lessons learned.

The use of fit tested respirators in the workplace is required to protect health workers against airborne pathogens. The COVID-19 pandemic required rapid upscaling of fit testing which was achieved using the framework of a respiratory protection program. Implementing and sustaining such a program in the midst of a pandemic was challenging and required clear direction from a lead agency combined with stakeholder engagement.

Electronic monitoring of doffing using video surveillance to minimise error rate and increase safety at Howard Springs International Quarantine Facility.

BACKGROUND: Safe donning and doffing of personal protective equipment (PPE) are critical to prevent transmission of infectious diseases. Novel strategies to improve infection prevention and control (IPC) adherence can optimise safety. We describe and quantify video surveillance of doffing at an outdoor hotel quarantine facility led by the Australian Medical Assistance Team in the Northern Territory, Australia. METHODS: Motion-activated video cameras were installed in seven areas where personnel doffed PPE upon exit from an area dedicated to quarantined residents. Video footage was reviewed daily and compliance issues were identified using a standardised checklist and risk graded to initiate feedback. We collated audit data from 1 February to 18 April 2021 to describe trends by month, staff group, doffing component and risk. RESULTS: In 235 h of video footage, 364 compliance issues were identified, of which none were considered high-risk compromising to PPE integrity. Compliance issues were low risk (55/364, 15%) or moderate risk (309/364, 85%) and the most common issue was missed or inadequate hand hygiene (156/364, 43%). Compliance issues per minute of video footage reviewed decreased following introduction of the activity, from 24 per 1000 in February to 7 per 1000 in March and April. CONCLUSION: Video surveillance with feedback supported rapid response to improve IPC adherence in a challenging ambient environment. The activity focused on perfection to identify compliance issues that would go unreported in most healthcare settings and contributed to a suit of activities that prevented any high-risk PPE breaches or compromises to safety.

Early warning for healthcare acquired infections in neonatal care units in a low-resource setting using routinely collected hospital data: The experience from Haiti, 2014-2018.

In low-resource settings, detection of healthcare-acquired outbreaks in neonatal units relies on astute clinical staff to observe unusual morbidity or mortality from sepsis as microbiological diagnostics are often absent. We aimed to generate reliable (and automated) early warnings for potential clusters of neonatal late onset sepsis using retrospective data that could signal the start of an outbreak in an NCU in Port au Prince, Haiti, using routinely collected data on neonatal admissions. We constructed smoothed time series for late onset sepsis cases, late onset sepsis rates, neonatal care unit (NCU) mortality, maternal admissions, neonatal admissions and neonatal antibiotic consumption. An outbreak was defined as a statistical increase in any of these time series indicators. We created three outbreak alarm classes: 1) thresholds: weeks in which the late onset sepsis cases exceeded four, the late onset sepsis rates exceeded 10% of total NCU admissions and the NCU mortality exceeded 15%; 2) differential: late onset sepsis rates and NCU mortality were double the previous week; and 3) aberration: using the improved Farrington model for late onset sepsis rates and NCU mortality. We validated pairs of alarms by calculating the sensitivity and specificity of the weeks in which each alarm was launched and comparing each alarm to the weeks in which a single GNB positive blood culture was reported from a neonate. The threshold and aberration alarms were the strongest predictors for current and future NCU mortality and current LOS rates (p<0.0002). The aberration alarms were also those with the highest sensitivity, specificity, negative predictive value, and positive predictive value. Without microbiological diagnostics in NCUs in low-resource settings, applying these simple algorithms to routinely collected data show great potential to facilitate early warning for possible healthcare-acquired outbreaks of LOS in neonates. The methods used in this study require validation across other low-resource settings.
