Health care-associated infections in Canadian hospitals: still a major problem

"I think we did the best that we could in the space:" A qualitative study exploring individuals' experiences with three unconventional environments for patients with a delayed hospital discharge

BACKGROUND

Given growing hospital capacity pressures, persistent delayed discharges, and ongoing efforts to improve patient flow, the use of unconventional environments (newly created or repurposed areas for patient care) is becoming increasingly common. Despite this, little is known about individuals' experiences in providing or receiving care in these environments.

OBJECTIVES

The objectives of this study were to: (1) describe the characteristics of three unconventional environments used to care for patients experiencing a delayed discharge, and (2) explore individuals' experiences with the three unconventional environments.

METHODS

This was a multi-method qualitative study of three unconventional environments in Ontario, Canada. Data were collected through semi-structured interviews and observations. Participants included patients, caregivers, healthcare providers, and clinical managers who had experience with delayed discharges. In-person observations of two environments were conducted. Interviews were transcribed and notes from the observations were recorded. Data were coded and analyzed thematically.

RESULTS

Twenty-nine individuals participated. Three themes were identified for unconventional environments: (1) implications on the physical safety of patients; (2) implications on staffing models and continuity of care; and, (3) implications on team interactions and patient care. Participants discussed how the physical set-up of some unconventional spaces was not conducive to patient needs, especially those with cognitive impairment. Limited space made it difficult to maintain privacy and develop social relationships. However, the close proximity of team members allowed for more focused collaborations regarding patient care and contributed to staff fulfilment. A smaller, consistent care team and access to onsite physicians seemed to foster improved continuity of care.

CONCLUSIONS

There is potential to learn from multi-stakeholder perspectives in unconventional environments to improve experiences and optimize patient care. Key considerations include keeping hallways and patient rooms clear, having communal spaces for activities and socialization, co-locating team members to improve interactions and access to resources, and ensuring a consistent care team.

Sustainable Purchasing Practices: A Comparison of Single-use and Reusable Pulse Oximeters in the Emergency Department

Background

Delivering healthcare requires significant resources and creates waste that pollutes the environment, contributes to the climate crisis, and harms human health. Prior studies have generally shown durable, reusable medical devices to be environmentally superior to disposables, but this has not been investigated for pulse oximetry probes.

Objective

Our goal was to compare the daily carbon footprint of single-use and reusable pulse oximeters in the emergency department (ED).

Methods

Using a Life Cycle Assessment (LCA), we analyzed greenhouse gas (GHG) emissions from pulse oximeter use in an urban, tertiary care ED, that sees approximately 150 patients per day. Low (387 uses), moderate (474 uses), and high use (561 uses), as well as cleaning scenarios, were modelled for the reusable oximeters and compared to the daily use of single-use oximeters (150 uses). We calculated GHG emissions, measured in kilograms of carbon dioxide equivalents (kgCO2e), across all life cycle stages using life-cycle assessment software and the ecoinvent database. We also carried out an uncertainty analysis using Monte Carlo methodology and calculated the break-even point for reusable oximeters.

Results

Per day of use, reusable oximeters produced fewer greenhouse gases in low-, moderate-, and high-use scenarios compared to disposable oximeters: 3.9 kgCO2e, 4.9 kgCO2e, 5.7 kgCO2e vs 23.4 kgCO2e, respectively). An uncertainty analysis showed there was no overlap in emissions, and a sensitivity analysis found reusable oximeters only need to be used 2.3 times before they match the emissions created by a single disposable oximeter. Use phases associated with the greatest emissions varied between oximeters, with the cleaning phase of reusables responsible for the majority of its GHG emissions (99%) compared to the production phases of the single-use oximeter (74%).

Conclusion

Reusable pulse oximeters generated fewer greenhouse gas emissions per day of use than their disposable counterparts. Given that the pulse oximeter is an ubiquitous piece of medical equipment used in emergency care globally, carbon emissions could be significantly reduced if EDs used reusable rather than single-use, disposable oximeters.

The Canadian Nosocomial Infection Surveillance Program: Keeping an eye on antimicrobial resistance in Canadian hospitals since 1995

Surveillance is essential to inform evidence-based policy and control measures that combat antimicrobial resistance (AMR). The Canadian Nosocomial Infection Surveillance Program (CNISP) collaborates with 88 sentinel hospitals across Canada to conduct prospective surveillance of infections and antimicrobial resistant organisms important to hospital infection prevention and control. This article aims to increase awareness of CNISP hospital-based surveillance activities. Since its inception in 1995, the scope of CNISP has expanded to include community-associated infections, outpatient Clostridioides difficile infections, viral respiratory infections such as coronavirus disease 2019, and emerging pathogens such as Candida auris. This change in scope, along with expansion to include rural, northern and community hospitals, has improved the generalizability of CNISP surveillance data. To generate actionable surveillance data, CNISP integrates demographic and clinical data abstracted from patient charts with molecular and microbiological data abstracted from laboratory testing. These data serve as a benchmark for participating hospitals and stakeholders to assess the burden of AMR in hospital and intervene as needed. Further, CNISP surveillance data are now available on a public-facing data blog that provides interactive visualizations and data syntheses sooner than peer-reviewed publications. Future directions of CNISP include the Simplified Dataset, which will capture aggregate AMR data from hospitals outside of the CNISP network, surveillance in long-term care facilities and a fourth point prevalence survey. Given its strengths and future directions, CNISP is well positioned to serve as the reference point for hospital-based AMR data in Canada.

Assessment of cleaning methods on bacterial burden of hospital privacy curtains: a pilot randomized controlled trial

Healthcare-associated infections (HAIs) are an important global issue, leading to poor patient outcomes. A potential route of transmission of HAIs is through contact with hospital privacy curtains. The aim of this study is to evaluate cleaning on reduction of curtain bacterial burden. In this pilot cluster randomized controlled trial we compared the bacterial burden between three groups of 24 curtains on a regional burn/plastic surgery ward. A control group was not cleaned. Two groups were cleaned at 3-4 day intervals with either disinfectant spray or wipe. The primary outcome was the difference in mean CFU/cm² between day 0 to day 21. The secondary outcome was the proportion of curtains contaminated with Methicillin-resistant Staphylococcus aureus (MRSA). By day 21, the control group was statistically higher (2.2 CFU/cm²) than spray (1.3 CFU/cm²) or wipe (1.5 CFU/cm²) (p < 0.05). After each cleaning at 3-4 day intervals, the bacterial burden on the curtains reduced to near day 0 levels; however, the level increased again over the intervening 3-4 days. By day 21, 64% of control curtains were contaminated with MRSA compared to 10% (spray) and 5% (wipe) (p < 0.05). This study show that curtains start clean and progressively become contaminated with bacteria. Regularly cleaning curtains with disinfectant spray or wipes reduces bacterial burden and MRSA contamination.

Healthcare-associated infections and antimicrobial resistance in Canadian acute care hospitals, 2014-2018

Background

Healthcare-associated infections (HAIs) and antimicrobial resistance (AMR) pose serious threats to the health of Canadians due to increased morbidity, mortality and healthcare costs. Epidemiologic and laboratory surveillance data, collected through the Canadian Nosocomial Infection Surveillance Program, are used to inform infection prevention and control and antimicrobial stewardship programs and policies. The objective of this study was to describe the epidemiologic and laboratory characteristics and trends of HAIs and AMR from 2014 to 2018 using surveillance data provided by Canadian hospitals participating in the Canadian Nosocomial Infection Surveillance Program.

Methods

Data were collected from 70 Canadian sentinel hospitals between January 1, 2014 and December 31, 2018 for Clostridioides difficile infection (CDI), methicillin-resistant Staphylococcus aureus bloodstream infections, vancomycin-resistant Enterococci bloodstream infections and carbapenemase-producing Enterobacteriaceae. Case counts, rates, outcome data, molecular characterization and antimicrobial resistance profiles are presented. Additionally, hospital-level Escherichia coli antibiogram data were collected and are described.

Results

Increases in rates per 10,000 patient-days were observed for methicillin-resistant S. aureus bloodstream infections (59%; 0.66-1.05, p=0.023) and vancomycin-resistant Enterococci bloodstream infections (143%; 0.14-0.34, p=0.023). However, CDI rates decreased by 12.5% between 2015 and 2018 (from 6.16-5.39, p=0.042). Carbapenemase-producing Enterobacteriaceae infection rates remained low and stable whereas colonization increased by 375% (0.04-0.19; p=0.014).

Conclusion

Ongoing efforts to prevent HAIs and reduce AMR in Canada require consistent, standardized surveillance data from acute care hospitals. Increased collaboration with provincial, territorial and international partners in infection prevention and control, as well as antimicrobial stewardship, will be essential in reducing the burden of observed HAIs (including antimicrobial resistant organisms).
