Item Cleaning Time and Motion: An Observational Study on the Time Required to Clean Shared Medical Equipment in Hospitals Effectively(Elsevier, 2024) Matterson, Georgia; Browne, Katrina; Tehan, Peta E.; Russo, Philip L.; Kiernan, Martin; Mitchell, Brett G.Background Despite the important role that cleaning plays in reducing the risk of healthcare-associated infections, no research has been undertaken to quantify the time required for effective cleaning and disinfection of different pieces of shared medical equipment commonly used in hospitals. This short report presents the results from a study that aimed to quantify the time required to clean common pieces of shared medical equipment effectively. Methods An observational time and motion study was conducted in a nursing simulation laboratory to determine the time required for effective cleaning and disinfection of 12 pieces of shared medical equipment commonly used in hospital. After training, the participants cleaned and disinfected equipment, with the time taken to clean recorded. Cleaning was deemed to be effective if ≥80% of ultraviolet fluorescent dots were removed during the cleaning process. Main results The time to clean equipment effectively ranged from 50 s [blood glucose testing kit; 95% confidence interval (CI) 0:40–1:00 (min:s)] to 3 min 53 s [medication trolley; 95% CI 3:36–4:11 (min:s)]. The intravenous stand was cleaned most effectively, with 100% of dots removed (N = 100 dots). In contrast, the bladder scanner was the most difficult to clean, with 12 attempts required to meet the 80% threshold for effective cleaning. Conclusion This study will inform staffing and training requirements to plan the cleaning and disinfection of shared medical equipment effectively. The findings can also be used for business cases, and in future cost-effectiveness evaluations of cleaning interventions that include shared medical equipment.Item Air Purifiers and Acute Respiratory Infections: A Randomised Clinical Trial(JAMA Network, 2024) Thottiyil Sultanmuhammed Abdul Khadar, Bismi; Sim, Jenny; McDonald, Vanessa M.; McDonagh, Julee; Clapham, Matthew; Mitchell, Brett G.Importance The effectiveness of in-room air purification for the reduction of acute respiratory infections (ARIs) in residential aged-care facilities (RACFs) is unknown. Objective To investigate the effectiveness of in-room air purifiers with high-efficiency particulate air (HEPA)–14 filters in reducing the incidence of ARIs among residents of RACFs. Design, Setting, and Participants This randomized clinical trial used a multicenter, double-blind, 2-period, 2-treatment crossover design for 6 months from April 7 to October 26, 2023, in 3 RACFs with a bed capacity of 50 to 100 in New South Wales, Australia. The purposive sampling approach included permanent residents in private rooms in the enrolled RACFs. Data collection was performed every 2 weeks and required no additional follow-up beyond the final data collection on October 31, 2023. Intervention An air purifier containing a HEPA-14 filter was placed in rooms of participants in the intervention group, and an air purifier without a HEPA-14 filter was placed in rooms of the control participants. The groups crossed over after 3 months. Main Outcomes and Measures The primary outcome was the incidence of ARIs, assessed with logistic mixed-model regression. Results Among 135 participants randomized (70 to the intervention-first group and 65 to the control-first group), 78 (57.8%) were female; mean (SD) age was 85.2 (8.6) years. In the intention-to-treat analysis, the use of air purifiers with HEPA-14 filters did not reduce ARIs compared with the control (OR, 0.57; 95% CI, 0.32-1.04; P = .07). Among the 104 participants who completed the entire study, the intervention reduced ARI incidence from 35.6% (37 participants) in the control group to 24.0% (25 participants) in the intervention group (OR, 0.53; 95% CI, 0.28-1.00; P = .048). Conclusions and Relevance In this clinical trial investigating use of air purifiers with HEPA-14 filters for reducing ARIs, no significant between-group difference was found in the intention-to-treat analysis. However, a significant reduction in ARIs was identified among participants who completed the entire study. These findings may help inform future large-scale studies of respiratory infectious diseases.Item Oral Care Practices and Hospital-acquired Pneumonia Prevention: A National Survey of Australian Nurses(Elsevier, 2024) Tehan, Peta E.; Browne, Katrina; Matterson, Georgia; Cheng, Allen C.; Dawson, Sonja; Graves, Nicholas; Johnson, Douglas; Kiernan, Martin; Madhuvu, Auxillia; Marshall, Caroline; McDonagh, Julee; Northcote, Maria; O'Connor, Jayne; Orr, Liz; Rawson, Helen; Russo, Philip; Sim, Jenny; Stewardson, Andrew J.; Wallace, Janet; White, Nicole; Wilson, Rhonda; Mitchell, Brett G.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.Item Which Trial do we Need? Gown and Glove use Versus Standard Precautions for Patients Colonized or Infected with methicillin-resistant Staphylococcus aureus or vancomycin-resistant Enterococcus(Elsevier, 2024-08) Browning, Sarah; White, Nicole M.; Raby, Edward; Davis, Joshua S.; Mitchell, Brett G.Background Gown and glove use as a component of ‘contact precautions’ was first recommended by the United States Healthcare Infection Control Practices Advisory Committee in 1996 and remains widely adhered to today. Despite a lack of randomized trial evidence in support of this practice, donning of gowns and gloves upon entry to the patient area (room or cubicle) continues to be ‘strongly recommended’ when the patient is infected or colonized with pathogens of epidemiological importanceItem Infection Prevention and Control Programme Priorities for Sustainable Health and Environmental Systems(Springer Nature, 2024-02-01) Saravanos, Gemma L.; Islam, Md Saiful; Huang, Yuanfei; Basseal, Jocelyne M.; Seale, Holly; Mitchell, Brett G.; Sheel, MeruInfection prevention and control (IPC) programmes reduce infection risk for patients, health workers, and the community. They are fundamental to achieving resilient, responsive, and sustainable health systems that align with the Sustainable Development Goals. Paradoxically, IPC programmes contribute to environmental harm, and this must be addressed alongside longstanding programme priorities.Item Patient Perspectives of Healthcare Associated Infection(Australasian College for Infection Prevention and Control, 2022) Mitchell, Brett G.; Northcote, Maria; Rickett, Carolyn; Russo, Phil; Amin, Maham; De Souza, Fiona; Pearce, Kirsty; Sim, Jenny; Curryer, CassieItem Healthcare-associated Infections in Australia : Principles and Practice of Infection Prevention and Control.(Elsevier, 2024) Mitchell, Brett G.; Shaban, Ramon Z.; Russo, Philip L.; MacBeth, DeboroughItem 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(2023-07-03) Russo, Philip; Graham, Kirsty; Lydeamore, Michael; Busija, Ljoudmila; Curtis, Stephanie; Ferguson, John K.; Kerr, Lucille; Stewardson, Andrew J.; Mitchell, Brett G.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.
Item Risk of Organism Acquisition from Prior Room Occupants: An Updated Systematic Review(2023-09-01) Kiernan, Martin; Browne, Katrina; Rawson, Helen; Maillard, Jean-Yves; Russo, Philip; Thottiyil Sultanmuhammed Abdul Khadar, Bismi; Sims, Jenny; Ford, Sindi; Dancer, Stephanie; McDonagh, Julee; Mitchell, Brett G.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.
Item Have Gloves and Gowns had their day? An Australian and New Zealand Practice and Attitudes Survey about Contact Precautions for MRSA and VRE Colonisation(2023-08-01) Mitchell, Brett G.; Davis, Joshua; Browning, SarahBackground
‘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.
