How to choose between single-use and reusable medical materials for sustainable nursing: Methodological lessons learned from a national study.

AIM: To demonstrate and reflect upon the methodological lessons by which healthcare organizations can address questions of environmental sustainability related to single-use healthcare materials. DESIGN: A cross-sectional multi-centre study in hospitals was performed, followed by an exploratory analysis of the sustainability of commonly used healthcare materials. METHODS: A hospital survey was conducted to collect the procurement data for single-use medical materials. Based on consumption and cost, five single-use medical materials with sustainable alternatives were selected using different reuse strategies. Single-use and reusable materials were assessed through an exploratory literature review and document study based on four parameters: environmental sustainability, safety, cost and efficiency. RESULTS: A pragmatic method emerged from this study, providing healthcare facilities with tools to select environmentally sustainable alternatives to replace single-use options. First, an inventory of single-use medical materials consumed was collected. Next, single-use materials were prioritized for further study based on criteria such as cost, volume of the material, feasibility and input of stakeholders. We then analysed the prioritized single-use materials and their alternatives based on life cycle assessments or available information on their different life stages. Finally, we assessed safety, costs and efficiency related to the process following the use of the medical material. CONCLUSION: This pragmatic method can guide healthcare institutions in making the most sustainable choices of medical materials and achieving sustainability goals within their institutions and nationwide. IMPACT: Patient care involves a large consumption of single-use medical materials with considerable environmental impact. A pragmatic method was developed to guide healthcare institutions in making the most sustainable choices regarding the use of single-use healthcare materials. Healthcare institutions, ideally represented by a green team including nurses and other relevant professionals, can use this method to reduce the use of single-use medical materials, thereby yielding positive outcomes for the entire population.

Implementation of the Infection Risk Scan (IRIS) in nine hospitals in the Belgian-Dutch border region (i-4-1-Health project).

BACKGROUND: A tool, the Infection Risk Scan has been developed to measure the quality of infection control and antimicrobial use. This tool measures various patient-, ward- and care-related variables in a standardized way. We describe the implementation of this tool in nine hospitals in the Dutch/Belgian border area and the obtained results. METHODS: The IRIS consists of a set of objective and reproducible measurements: patient comorbidities, (appropriate) use of indwelling medical devices, (appropriate) use of antimicrobial therapy, rectal carriage of Extended-spectrum beta-lactamase producing Enterobacterales and their clonal relatedness, environmental contamination, hand hygiene performance, personal hygiene of health care workers and presence of infection prevention preconditions. The Infection Risk Scan was implemented by an expert team. In each setting, local infection control practitioners were trained to achieve a standardized implementation of the tool and an unambiguous assessment of data. RESULTS: The IRIS was implemented in 34 wards in six Dutch and three Belgian hospitals. The tool provided ward specific results and revealed differences between wards and countries. There were significant differences in the prevalence of ESBL-E carriage between countries (Belgium: 15% versus The Netherlands: 9.6%), environmental contamination (median adenosine triphosphate (ATP) level Belgium: 431 versus median ATP level The Netherlands: 793) and calculated hand hygiene actions based on alcohol based handrub consumption (Belgium: 12.5/day versus The Netherlands: 6.3/day) were found. CONCLUSION: The Infection risk Scan was successfully implemented in multiple hospitals in a large cross-border project and provided data that made the quality of infection control and antimicrobial use more transparent. The observed differences provide potential targets for improvement of the quality of care.

Feedback of ATP measurement as a tool for reducing environmental contamination in hospitals in the Dutch/Belgian border area.

DESIGN: A two-phase prospective intervention study. OBJECTIVE: The objective of this study was to determine if feedback of adenosine triphosphate (ATP) measurements decreases environmental contamination within hospitals in the Dutch/Belgian border area. METHODS: Standardized ATP measurements were conducted in nine hospitals on pre-defined fomites. Four different fomite groups were defined: medical devices, patient-bound materials, ward-bound materials and sanitary items. ATP results were reported in relative light unit (RLU), RLU >1000 was considered as 'not clean.' Two rounds of ATP measurements were conducted. After the first round of ATP measurements, results were provided to the wards and cleaning staff. The second round of ATP measurements was performed one year later. The amount of surface contamination before and after the feedback was compared. RESULTS: In total 1923 ATP measurements were performed. Before feedback 960 ATP measurements were conducted and after feedback 963 were conducted. The overall median reduction in RLU was 381 (P < 0.001), from 568 before feedback to 187 afterward. In each hospital there was a reduction of the median RLU after feedback. CONCLUSIONS: Substantial reductions in RLU values were found after feedback of ATP measurements. Feedback of ATP measurement in itself was associated with a major reduction of surface contamination in hospitals.

A recurrent and transesophageal echocardiography-associated outbreak of extended-spectrum ß-lactamase-producing Enterobacter cloacae complex in cardiac surgery patients.

Background: We report a recurrent outbreak of postoperative infections with extended-spectrum ß-lactamase (ESBL)-producing E. cloacae complex in cardiac surgery patients, describe the outbreak investigation and highlight the infection control measures. Methods: Cases were defined as cardiac surgery patients in Ghent University Hospital who were not known preoperatively to carry ESBL-producing E. cloacae complex and who postoperatively had a positive culture for this multiresistant organism between May 2017 and January 2018. An epidemiological investigation, including a case-control study, and environmental investigation were conducted to identify the source of the outbreak. Clonal relatedness of ESBL-producing E. cloacae complex isolates collected from case patients was assessed using whole-genome sequencing-based studies. Results: Three separate outbreak episodes occurred over the course of 9 months. A total of 8, 4 and 6 patients met the case definition, respectively. All but one patients developed a clinical infection with ESBL-producing E. cloacae complex, most typically postoperative pneumonia. Overall mortality was 22% (4/18). Environmental cultures were negative, but epidemiological investigation pointed to transesophageal echocardiography (TEE) as the outbreak source. Of note, four TEE probes showed a similar pattern of damage, which very likely impeded adequate disinfection. The first and second outbreak episode were caused by the same clone, whereas a different strain was responsible for the third episode. Conclusions: Health professionals caring for cardiac surgery patients and infection control specialists should be aware of TEE as possible infection source. Caution must be exercised to prevent and detect damage of TEE probes.
