Cost-effectiveness of an Environmental Cleaning Bundle for Reducing Healthcare-associated Infections.

BACKGROUND: Healthcare-associated infections (HAIs) remain a significant patient safety issue, with point prevalence estimates being ~5% in high-income countries. In 2016-2017, the Researching Effective Approaches to Cleaning in Hospitals (REACH) study implemented an environmental cleaning bundle targeting communication, staff training, improved cleaning technique, product use, and audit of frequent touch-point cleaning. This study evaluates the cost-effectiveness of the environmental cleaning bundle for reducing the incidence of HAIs. METHODS: A stepped-wedge, cluster-randomized trial was conducted in 11 hospitals recruited from 6 Australian states and territories. Bundle effectiveness was measured by the numbers of Staphylococcus aureus bacteremia, Clostridium difficile infection, and vancomycin-resistant enterococci infections prevented in the intervention phase based on estimated reductions in the relative risk of infection. Changes to costs were defined as the cost of implementing the bundle minus cost savings from fewer infections. Health benefits gained from fewer infections were measured in quality-adjusted life-years (QALYs). Cost-effectiveness was evaluated using the incremental cost-effectiveness ratio and net monetary benefit of adopting the cleaning bundle over existing hospital cleaning practices. RESULTS: Implementing the cleaning bundle cost $349 000 Australian dollars (AUD) and generated AUD$147 500 in cost savings. Infections prevented under the cleaning bundle returned a net monetary benefit of AUD$1.02 million and an incremental cost-effectiveness ratio of $4684 per QALY gained. There was an 86% chance that the bundle was cost-effective compared with existing hospital cleaning practices. CONCLUSIONS: A bundled, evidence-based approach to improving hospital cleaning is a cost-effective intervention for reducing the incidence of HAIs.

Protocol: investigating the effectiveness and cost benefit of a lifestyle intervention targeting type 2 diabetes in Australia.

BACKGROUND: Type 2 Diabetes Mellitus (T2DM) has become an endemic disease. A number of interrelated factors increase the risk of the onset of T2DM, however much of the pathogenesis of the disease is associated with lifestyle. A number of studies have indicated that adopting positive lifestyle changes can successfully prevent or delay the onset of T2DM in a number of different population groups. The CHIP intervention is a lifestyle program that has been shown in over more than 30 published papers have indicated that the CHIP intervention leads to dramatic improvement in the indicators of T2DM these diseases of lifestyle. METHODS: A randomized control trial will be conducted involving 150 individuals with an established diagnosis of T2DM. All participants will continue to receive usual ongoing diabetes care, however, the intervention group (75 individuals) will in addition participate in a 12-week CHIP lifestyle intervention programme followed by a further 9 months of monthly follow-up appointments. Approval for funding was obtained on 30 June 2017. DISCUSSION: The outcomes of this study have the potential to inform decisions about patient treatment and potentially provide incentive for the provision of funded lifestyle-based preventive and restorative programs for patients diagnosed with T2DM. TRIAL REGISTRATION: This trial is registered as an initial version with the Australia New Zealand Clinical Trials Registry ( http://www.anzctr.org.au/ ), registration number ACTRN12617001233314. Registered on 23/08/2017. No enrollments in the study to date.

Hospital Staffing and Health Care-Associated Infections: A Systematic Review of the Literature.

BACKGROUND: Previous literature has linked the level and types of staffing of health facilities to the risk of acquiring a health care-associated infection (HAI). Investigating this relationship is challenging because of the lack of rigorous study designs and the use of varying definitions and measures of both staffing and HAIs. METHODS: The objective of this study was to understand and synthesize the most recent research on the relationship of hospital staffing and HAI risk. A systematic review was undertaken. Electronic databases MEDLINE, PubMed, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched for studies published between January 1, 2000, and November 30, 2015. RESULTS: Fifty-four articles were included in the review. The majority of studies examined the relationship between nurse staffing and HAIs (n = 50, 92.6%) and found nurse staffing variables to be associated with an increase in HAI rates (n = 40, 74.1%). Only 5 studies addressed non-nurse staffing, and those had mixed results. Physician staffing was associated with an increased HAI risk in 1 of 3 studies. Studies varied in design and methodology, as well as in their use of operational definitions and measures of staffing and HAIs. CONCLUSION: Despite the lack of consistency of the included studies, overall, the results of this systematic review demonstrate that increased staffing is related to decreased risk of acquiring HAIs. More rigorous and consistent research designs, definitions, and risk-adjusted HAI data are needed in future studies exploring this area.

Healthcare-associated infections in Australia: tackling the 'known unknowns'.

Australia does not have a national healthcare-associated infection (HAI) surveillance program. Without national surveillance, we do not understand the burden of HAIs, nor can we accurately assess the effects of national infection prevention initiatives. Recent research has demonstrated disparity between existing jurisdictional-based HAI surveillance activity while also identifying broad key stakeholder support for the establishment of a national program. A uniform surveillance program will also address growing concerns about hospital performance measurements and enable public reporting of hospital data.

Ciprofloxacin resistance in community- and hospital-acquired Escherichia coli urinary tract infections: a systematic review and meta-analysis of observational studies.

BACKGROUND: During the last decade the resistance rate of urinary Escherichia coli (E. coli) to fluoroquinolones such as ciprofloxacin has increased. Systematic reviews of studies investigating ciprofloxacin resistance in community- and hospital-acquired E. coli urinary tract infections (UTI) are absent. This study systematically reviewed the literature and where appropriate, meta-analysed studies investigating ciprofloxacin resistance in community- and hospital-acquired E. coli UTIs. METHODS: Observational studies published between 2004 and 2014 were identified through Medline, PubMed, Embase, Cochrane, Scopus and Cinahl searches. Overall and sub-group pooled estimates of ciprofloxacin resistance were evaluated using DerSimonian-Laird random-effects models. The I(2) statistic was calculated to demonstrate the degree of heterogeneity. Risk of bias among included studies was also investigated. RESULTS: Of the identified 1134 papers, 53 were eligible for inclusion, providing 54 studies for analysis with one paper presenting both community and hospital studies. Compared to the community setting, resistance to ciprofloxacin was significantly higher in the hospital setting (pooled resistance 0.38, 95% CI 0.36-0.41 versus 0.27, 95% CI 0.24-0.31 in community-acquired UTIs, P < 0.001). Resistance significantly varied by region and country with the highest resistance observed in developing countries. Similarly, a significant rise in resistance over time was seen in studies reporting on community-acquired E. coli UTI. CONCLUSIONS: Ciprofloxacin resistance in E. coli UTI is increasing and the use of this antimicrobial agent as empirical therapy for UTI should be reconsidered. Policy restrictions on ciprofloxacin use should be enhanced especially in developing countries without current regulations.

A major reduction in hospital-onset Staphylococcus aureus bacteremia in Australia-12 years of progress: an observational study.

BACKGROUND: Staphylococcus aureus bacteremia (SAB) is a serious cause of morbidity and mortality. This longitudinal study describes significant reductions in hospital-onset SAB (HO-SAB) in Australian hospitals over the past 12 years. METHODS: An observational cohort study design was used. Prospective surveillance of HO-SAB in 132 hospitals in Australia was undertaken. Aggregated data from all patients who acquired HO-SAB was collected (defined as 1 or more blood cultures positive for S. aureus taken from a patient who had been admitted to hospital for >48 hours). The primary outcome was the incidence of HO-SAB, including both methicillin-resistant (MRSA) and methicillin-susceptible (MSSA) S. aureus strains. RESULTS: A total of 2733 HO-SAB cases were identified over the study period, giving an aggregate incidence of 0.90 per 10 000 patient-days (PDs) (95% confidence interval [CI], .86-.93). There was a 63% decrease in the annual incidence, from 1.72 per 10 000 PDs in 2002 (95% CI, 1.50-1.97) to 0.64 per 10 000 PDs (95% CI, .53-.76) in 2013. The mean reduction per year was 9.4% (95% CI, -8.1% to -10.7%). Significant reductions in both HO-MRSA (from 0.77 to 0.18 per 10 000 PDs) and HO-MSSA (from 1.71 to 0.64 per 10 000 PDs) bacteremia were observed. CONCLUSIONS: There was a major and significant reduction in incidence of HO-SAB caused by both MRSA and MSSA in Australian hospitals since 2002. This reduction coincided with a range of infection prevention and control activities implemented during this time. It suggests that national and local efforts to reduce the burden of healthcare-associated infections have been very successful.

Increasing incidence of Clostridium difficile infection, Australia, 2011-2012.

OBJECTIVES: To report the quarterly incidence of hospital-identified Clostridium difficile infection (HI-CDI) in Australia, and to estimate the burden ascribed to hospital-associated (HA) and community-associated (CA) infections. DESIGN, SETTING AND PATIENTS: Prospective surveillance of all cases of CDI diagnosed in hospital patients from 1 January 2011 to 31 December 2012 in 450 public hospitals in all Australian states and the Australian Capital Territory. All patients admitted to inpatient wards or units in acute public hospitals, including psychiatry, rehabilitation and aged care, were included, as well as those attending emergency departments and outpatient clinics. MAIN OUTCOME MEASURES: Incidence of HI-CDI (primary outcome); proportion and incidence of HA-CDI and CA-CDI (secondary outcomes). RESULTS: The annual incidence of HI-CDI increased from 3.25/10 000 patient-days (PD) in 2011 to 4.03/10 000 PD in 2012. Poisson regression modelling demonstrated a 29% increase (95% CI, 25% to 34%) per quarter between April and December 2011, with a peak of 4.49/10 000 PD in the October-December quarter. The incidence plateaued in January-March 2012 and then declined by 8% (95% CI, - 11% to - 5%) per quarter to 3.76/10 000 PD in July-September 2012, after which the rate rose again by 11% (95% CI, 4% to 19%) per quarter to 4.09/10 000 PD in October-December 2012. Trends were similar for HA-CDI and CA-CDI. A subgroup analysis determined that 26% of cases were CA-CDI. CONCLUSIONS: A significant increase in both HA-CDI and CA-CDI identified through hospital surveillance occurred in Australia during 2011-2012. Studies are required to further characterise the epidemiology of CDI in Australia.

Addressing the need for an infection prevention and control framework that incorporates the role of surveillance: a discussion paper.

AIM: To present a discussion on theoretical frameworks in infection prevention and control. BACKGROUND: Infection prevention and control programmes have been in place for several years in response to the incidence of healthcare-associated infections and their associated morbidity and mortality. Theoretical frameworks play an important role in formalizing the understanding of infection prevention activities. DESIGN: Discussion paper. DATA SOURCES: A literature search using electronic databases was conducted for published articles in English addressing theoretical frameworks in infection prevention and control between 1980-2012. RESULTS: Nineteen papers that included a reference to frameworks were identified in the review. A narrative analysis of these papers was completed. Two models were identified and neither included the role of surveillance. DISCUSSION: To reduce the risk of acquiring a healthcare-associated infection, a multifaceted approach to infection prevention is required. One key component in this approach is surveillance. The review identified two infection prevention and control frameworks, yet these are rarely applied in infection prevention and control programmes. Only one framework considered the multifaceted approach required for infection prevention. It did not, however, incorporate the role of surveillance. We present a framework that incorporates the role of surveillance into a biopsychosocial approach to infection prevention and control. CONCLUSION: Infection prevention and control programmes and associated research are led primarily by nurses. There is a need for an explicit infection prevention and control framework incorporating the important role that surveillance has in infection prevention activities. This study presents one framework for further critique and discussion.

Australian graduating nurses' knowledge, intentions and beliefs on infection prevention and control: a cross-sectional study.

BACKGROUND: In recent year, national bodies have been actively addressing the increasing concern on the spread of healthcare-associated infections (HAIs). The current study measures the knowledge, intentions and beliefs of third-year Australian nursing students on key infection prevention and control (IPC) concepts. METHODS: A cross-sectional study of final-year undergraduate nursing students from Schools of Nursing at six Australian universities was undertaken. Students were asked to participate in an anonymous survey. The survey explored knowledge of standard precautions and transmission based precautions. In addition intentions and beliefs towards IPC were explored. RESULTS: 349 students from six universities completed the study. 59.8% (95% CI 58.8-60.8%) of questions were answered correctly. Significantly more standard precaution questions were correctly answered than transmission-based precaution questions (p < 0.001). No association was found between self-reported compliance with IPC activities and gender or age. Certain infection control issues were correlated with the percentage of correctly answered transmission-based precaution questions. The participants were most likely to seek infection control information from an infection control professional. CONCLUSION: Knowledge on transmission-based precautions was substandard. As transmission-based precautions are the foundation of IPC for serious organisms and infections, education institutions should reflect on the content and style of educational delivery on this topic.

Gender differences in effectiveness of the Complete Health Improvement Program (CHIP) lifestyle intervention: an Australasian study.

ISSUE ADDRESSED: Complete Health Improvement Program (CHIP) is a lifestyle modification program that promotes healthy diet, physical activity and stress management techniques. Among US CHIP participants, differences in gender responsiveness to improvements in chronic disease risk factors were demonstrated. This study examined gender differences in outcomes to the CHIP intervention in Australasia. METHODS: Changes in body weight, blood pressure (BP), blood lipid profile and fasting plasma glucose (FPG) were assessed in 925 participants (34.3% men, mean age=56.0±12.5 years; 65.7% women, mean age=54.4±13.5 years) 30 days after program commencement. RESULTS: Significant reductions (P<0.001) in all biometrics measured were found for men and women but were greater among men for total (TC) and low-density lipoprotein cholesterol (LDL), triglycerides (TG), FPG, body mass index (BMI) and TC/high-density lipoprotein cholesterol (HDL) ratio. Participants with highest baseline classifications of BMI, systolic BP, blood lipids and FPG showed greatest reductions in 30 days. CONCLUSIONS: CHIP more effectively reduced chronic disease risk factors among men than women. All participants, but particularly men, entering the program with the greatest risk achieved the largest reductions. Possible physiological or behavioural factors include food preferences, making commitments and differential support modes. SO WHAT?: Developers of lifestyle intervention programs should consider gender differences in physiological and behavioural factors when planning interventions. In particular, developers should manage expectations of people entering lifestyle interventions to increase awareness that men tend to respond better than women. In addition, this is a call for further research to identify the underlying mechanisms responsible for the disproportionate responsiveness of males.

Oral care practices and hospital-acquired pneumonia prevention: A national survey of Australian nurses.

BACKGROUND: Hospital-acquired pneumonia (HAP) also known as non-ventilator associated pneumonia, is one of the most common infections acquired in hospitalised patients. Improving oral hygiene appears to reduce the incidence of HAP. This study aimed to describe current practices, barriers and facilitators, knowledge and educational preferences of registered nurses performing oral health care in the Australian hospital setting, with a focus on the prevention of HAP. We present this as a short research report. METHODS: We undertook a cross sectional online anonymous survey of Australian registered nurses. Participants were recruited via electronic distribution through existing professional networks and social media. The survey used was modified from an existing survey on oral care practice. RESULTS: The survey was completed by 179 participants. Hand hygiene was considered a very important strategy to prevent pneumonia (n = 90, 58%), while 45% (n = 71) felt that oral care was very important. The most highly reported barriers for providing oral care included: an uncooperative patient; inadequate staffing; and a lack of oral hygiene requisite. Patients' reminders, prompts and the provision of toothbrushes were common ways believed to help facilitate improvements in oral care. CONCLUSION: Findings from this survey will be used in conjunction with consumer feedback, to help inform a planned multi-centre randomised trial, the Hospital Acquired Pneumonia PrEveNtion (HAPPEN) study, aimed at reducing the incidence of HAP. Findings may also be useful for informing studies and quality improvement initiatives aimed at improving oral care to reduce the incidence of HAP.

Mortality and Clostridium difficile infection in an Australian setting.

AIM: To quantify the risk of death associated with Clostridium difficile infection, in an Australian tertiary hospital. BACKGROUND: Two reviews examining Clostridium difficile infection and mortality indicate that Clostridium difficile infection is associated with increased mortality in hospitalized patients. Studies investigating the mortality of Clostridium difficile infection in settings outside of Europe and North America are required, so that the epidemiology of Clostridium difficile infection in these regions can be understood and appropriate prevention strategies made. DESIGN: An observational non-concurrent cohort study design was used. METHODS: Data from all persons who had (exposed) and a matched sample of persons who did not have Clostridium difficile infection, for the calendar years 2007-2010, were analysed. The risk of dying within 30, 60, 90 and 180 days was compared using the two groups. Kaplan-Meier survival analysis and conditional logistic regression models were applied to the data to examine time to death and mortality risk adjusted for comorbidities using the Charlson Comorbidity Index. RESULTS: One hundred and fifty-eight cases of infection were identified. A statistically significant difference in all-cause mortality was identified between exposed and non-exposed groups at 60 and 180 days. In a conditional regression model, mortality in the exposed group was significantly higher at 180 days. CONCLUSION: In this Australian study, Clostridium difficile infection was associated with increased mortality. In doing so, it highlights the need for nurses to immediately instigate contact precautions for persons suspected of having Clostridium difficile infection and to facilitate a timely faecal collection for testing. Our findings support ongoing surveillance of Clostridium difficile infection and associated prevention and control activities.

Multimodal environmental cleaning strategies to prevent healthcare-associated infections.

Infection transmission in healthcare is multifaceted and by in large involves the complex interplay between a pathogen, a host and their environment. To prevent transmission, infection prevention strategies must also consider these complexities and incorporate targeted interventions aimed at all possible transmission pathways. One strategy to prevent and control infection is environmental cleaning. There are many aspects to an environmental cleaning strategy. We believe the key to successfully reducing the risk of healthcare-associated infections through the environment, is to design and implement a multimodal intervention. This paper aims to provide an overview of important considerations for designing a meaningful and sustainable environmental program for healthcare facilities.

Have gloves and gowns had their day? An Australian and New Zealand practice and attitudes survey about contact precautions for MRSA and VRE colonisation.

BACKGROUND: 'Contact precautions,' are recommended for hospitalised patients with known methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE) colonisation. Despite increasing observational evidence suggesting that gowns and gloves are of no added benefit over hand hygiene and environmental cleaning, guidelines continue to recommend them. METHODS: A cross-sectional online survey of infection prevention professionals, infectious diseases physicians and microbiologists in Australian and New Zealand hospitals was conducted. The purpose was to explore variations in current approaches to known MRSA and VRE colonisation, and determine clinical equipoise for a proposed randomised control trial (RCT) to withdraw the use of gowns and gloves in this setting. RESULTS: 226 responses from 122 hospitals across all Australian jurisdiction and multiple regions of New Zealand were received. While most hospitals implement contact precautions for MRSA (86%) and VRE (92%), variations based on MRSA and VRE subtypes are common. There was strong interest in removing glove and gown use for MRSA (72% and 73%, respectively) and VRE (70% and 68%, respectively). 62% of surveyed hospitals expressed interest in participating in a proposed cluster RCT comparing discontinuation of gown and glove use as part of contact precautions for MRSA and VRE, with their ongoing use. CONCLUSION: The mandated use of PPE in the context of MRSA and VRE colonisation warrants further examination. An RCT is needed to definitively address this issue and to promote a widespread change in practice, if warranted.

Moisturizers, Emollients, or Barrier Preparations for the Prevention of Pressure Injury: A Systematic Review and Meta-Analysis.

Significance: Pressure injuries are prevalent, yet preventable global health care problem estimated to affect 14% of hospital patients and up to 46% of aged care residents. One common prevention strategy is improving skin integrity through emollient therapy to optimize hydration and avoid skin breakdown. Therefore, this study aimed to review the literature and determine effectiveness of inert emollients, moisturizers, and barrier preparations compared with standard care, to prevent pressure injury in aged care or hospital settings. Recent Advances: Search terms were derived with database searches, including ProQuest, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medline, Science Direct, Scopus, and the Cochrane library. The Robins1 and Risk of Bias 2 (Rob2) quality appraisal tools were used. A meta-analysis of the effects of interventions was conducted (random effects). Four studies met the inclusion criteria, with heterogeneous quality. Pooling of nonrandomized studies found that the application of emollients, moisturizers or barrier preparations did not significantly reduce incidence of pressure injury compared with standard care (relative risk 0.50, 95% confidence interval: 0.15-1.63, Z = 1.15, p = 0.25). Critical Issues: This review suggests that the use of inert moisturizers, emollients, or barrier preparations for preventing pressure injuries was not effective to prevent pressure injury in aged care or hospital settings. However, there was a distinct lack of randomized controlled trials (RCTs), with only one meeting the inclusion criteria. Furthermore, most of the included studies did not report on the frequency of application of the product, making it difficult to determine if application was in line with current international guidelines. One included study, which utilized a combination of neutral body wash and emollient demonstrated a significant reduction in the development of stage one and two pressure injuries. This combination of care may further support skin integrity and should be further examined in future trials. Future Directions: Future studies should ideally be RCTs, which control for skin cleansing, and implement an inert moisturizer emollient or barrier preparation as part of a pressure injury reduction bundle of care. Standardization of the application of the product, the volume of product applied at each application, and the quality of the product should also be considered.

Air purifiers for reducing the incidence of acute respiratory infections in australian residential aged care facilities: A study protocol for a randomised control trial.

INTRODUCTION: Adults living in Residential Aged Care Facilities (RACFs) are highly susceptible to seasonal respiratory infections. Evidence indicates that the aerosols contaminated with virus particles in closed indoor spaces may play a significant role in the transmission of respiratory infections. In this protocol paper, we outline details of a planned RCT which aims to evaluate the effectiveness of portable in room air purifiers in reducing the risk of ARIs among residents in Australian RACFs. This study uses a multi-centre double-blind randomised crossover design. Three RACFs in a regional area of New South Wales will be invited to participate in the study. Air purifiers with or without high-efficiency particulate absorbing (HEPA) filters will be placed in the rooms of residents who are enrolled in the trial. The primary outcome will be a reduction in the incidence of ARI and the secondary outcomes will be the time to first infection, number of emergency department admissions, hospital admissions, and medical consultations due to an ARI. CONCLUSION: To our knowledge, this will be the first RCT using air purifiers in resident rooms to identify their effect in reducing ARIs in RACFs. If our findings indicate some potential benefit for in-room air purification, it will help provide support and justification for larger trials, which may include a facility wide approach to air purification.

The incidence of nosocomial bloodstream infection and urinary tract infection in Australian hospitals before and during the COVID-19 pandemic: an interrupted time series study.

BACKGROUND: The COVID-19 pandemic has had a significant impact on healthcare including increased awareness of infection prevention and control (IPC). The aim of this study was to explore if the heightened awareness of IPC measures implemented in response to the pandemic influenced the rates of healthcare associated infections (HAI) using positive bloodstream and urine cultures as a proxy measure. METHODS: A 3 year retrospective review of laboratory data from 5 hospitals (4 acute public, 1 private) from two states in Australia was undertaken. Monthly positive bloodstream culture data and urinary culture data were collected from January 2017 to March 2021. Occupied bed days (OBDs) were used to generate monthly HAI incidence per 10,000 OBDs. An interrupted time series analysis was undertaken to compare incidence pre and post February 2020 (the pre COVID-19 cohort and the COVID-19 cohort respectively). A HAI was assumed if positive cultures were obtained 48 h after admission and met other criteria. RESULTS: A total of 1,988 bloodstream and 7,697 urine positive cultures were identified. The unadjusted incident rate was 25.5 /10,000 OBDs in the pre-COVID-19 cohort, and 25.1/10,000 OBDs in the COVID-19 cohort. The overall rate of HAI aggregated for all sites did not differ significantly between the two periods. The two hospitals in one state which experienced an earlier and larger outbreak demonstrated a significant downward trend in the COVID-19 cohort (p = 0.011). CONCLUSION: These mixed findings reflect the uncertainty of the effect the pandemic has had on HAI's. Factors to consider in this analysis include local epidemiology, differences between public and private sector facilities, changes in patient populations and profiles between hospitals, and timing of enhanced IPC interventions. Future studies which factor in these differences may provide further insight on the effect of COVID-19 on HAIs.

A randomised controlled trial investigating the effect of improving the cleaning and disinfection of shared medical equipment on healthcare-associated infections: the CLEaning and Enhanced disiNfection (CLEEN) study.

BACKGROUND: Healthcare-associated infections (HAIs) are a common, costly, yet largely preventable complication impacting patients in healthcare settings globally. Improving routine cleaning and disinfection of the hospital environment has been shown to reduce the risk of HAI. Contaminated shared medical equipment presents a primary transmission route for infectious pathogens, yet is rarely studied. The CLEEN study will assess how enhanced cleaning and disinfection of shared medical equipment affects the rate of HAIs in a tertiary hospital setting. The initiative is an evidence-based approach combining staff training, auditing and feedback to environmental services staff to enhance cleaning and disinfection practices. METHODS: The CLEEN study will use a stepped wedge randomised controlled design in 10 wards of one large Australian hospital over 36 weeks. The intervention will consist of 3 additional hours per weekday for the dedicated cleaning and disinfection of shared medical equipment on each ward. The primary outcome is to demonstrate the effectiveness of improving the quality and frequency of cleaning shared medical equipment in reducing HAIs, as measured by a HAI point prevalence study (PPS). The secondary outcomes include the thoroughness of equipment cleaning assessed using fluorescent marker technology and the cost-effectiveness of the intervention. DISCUSSION: Evidence from the CLEEN study will contribute to future policy and practice guidelines about the cleaning and disinfection of shared medical equipment. It will be used by healthcare leaders and clinicians to inform decision-making and implementation of best-practice infection prevention strategies to reduce HAIs in healthcare facilities.

Risk of organism acquisition from prior room occupants: An updated systematic review.

BACKGROUND: Evidence from a previous systematic review indicates that patients admitted to a room where the previous occupant had a multidrug-resistant bacterial infection resulted in an increased risk of subsequent colonisation and infection with the same organism for the next room occupant. In this paper, we have sought to expand and update this review. METHODS: A systematic review and meta-analysis was undertaken. A search using Medline/PubMed, Cochrane and CINHAL databases was conducted. Risk of bias was assessed by the ROB-2 tool for randomised control studies and ROBIN-I for non-randomised studies. RESULTS: From 5175 identified, 12 papers from 11 studies were included in the review for analysis. From 28,299 patients who were admitted into a room where the prior room occupant had any of the organisms of interest, 651 (2.3%) were shown to acquire the same species of organism. In contrast, 981,865 patients were admitted to a room where the prior occupant did not have an organism of interest, 3818 (0.39%) acquired an organism(s). The pooled acquisition odds ratio (OR) for all the organisms across all studies was 2.45 (95% CI: 1.53-3.93]. There was heterogeneity between the studies (I2 89%, P < 0.001). CONCLUSION: The pooled OR for all the pathogens in this latest review has increased since the original review. Findings from our review provide some evidence to help inform a risk management approach when determining patient room allocation. The risk of pathogen acquisition appears to remain high, supporting the need for continued investment in this area.

Healthcare-associated infections: getting the balance right in safety and quality v. public reporting.

Healthcare settings are dangerous places. For those receiving care, the risk of unintended harm from healthcare failures continues to be significant. Given this, there is a need to monitor standards in healthcare, not only to identify potential issues, but also to plan and evaluate interventions aimed at improving healthcare standards. Public reporting of performance standards is one aspect to monitoring standards, but not the only one. Public reporting also brings with it challenges. This perspective explores the recent move to publicly report one healthcare-associated infection (HAI) on the MyHospitals website and comments on the broader issue of using existing HAI data for the purposes of public reporting.
