Copper in Guidelines and Rating Systems

As the evidence base for copper alloy touch surfaces has grown, and awareness becomes more widespread, they are being included in infection prevention and control horizon scanning and guidance, healthcare accreditation systems and green and healthy building schemes, aound the world. This page provides an overview of these schemes with pointers to the relevant sections.

Infection Prevention and Control

Healthcare Accreditation Scheme, Poland, 2016

National Centre for Quality Assessment in Healthcare

Centrum Monitorowania Jakości w Ochronie Zdrowia (CMJ) is a Polish Ministry of Health body and WHO collaborating centre which operates a hospital accreditation scheme to improve the quality and efficacy of services and patient safety standards. In order to obtain accreditation, hospitals are required to demonstrate appropriate procedures are in place and followed. It carries out a structured process of external assessment, based on measurable criteria and accepted standards which it publishes.

In the accreditation standards, Chapter lX 'Infection Control' provides guidelines concerning the prevention of pathogen transmission by touch and states:

Reduction of microbial transmission should be achieved, inter alia, using frequently touched surfaces made from metals with antimicrobial properties, such as copper, brass and bronze, as per the US Environmental Protection Agency's registration.

CMJ's role is comparable to the Care Quality Commission and the National Institute for Health and Care Excellence in England.

EPIC3: National Evidence-Based Guidelines for Preventing Healthcare-Associated Infections in NHS Hospitals in England, 2014

In these NICE-accredited guidelines, copper is recognised under 'emerging technology' for its ability to continuously and significantly reduce bioburden:

Four non-randomised, experimental studies, conducted in clinical environments, demonstrated significant reductions in microbial burden of between 80% and 90% on high-touch surfaces coated with metallic copper and/or its alloys compared with similar non-copper surfaces.

ECRI: Top 10 Technology Watch List for the Hospital C-Suite, 2014

ECRI published a Watch List 'Copper Surfaces: How Many Are Needed in a Hospital Room to Prevent Hospital-acquired Infections?' which concludes that implementation of copper and copper alloy surfaces might not only improve patient health outcomes, but might also save the healthcare system significant funds.

The ECRI Institute is a globally-renowned non-profit organisation, dedicated to bringing the discipline of applied scientific research to discover which medical procedures, devices, drugs and processes are best, to enable its international members to improve patient care.

CNESH: Top 10 New & Emerging Health Technology Watch List, 2014

The Canadian Network for Environmental Scanning in Health published this Watch List reporting:

Lower levels of bacteria on copper surfaces in an ICU setting have led to a reduction in rates of healthcare-acquired infection. This new technology, which is intended to deliver antibacterial activity in between regular cleaning intervals, is purported to have antibacterial properties that last the product’s lifetime. It appears the antimicrobial copper surfaces achieve a 99.9% reduction in both gram-negative and gram-positive bacteria within two hours of exposure.

AHRQ: Understanding the Role of Facility Design in the Acquisition and Prevention of Healthcare-Associated Infections, 2013

The Agency for Healthcare Research and Quality's (AHRQ) mission is to produce evidence to make healthcare safer, higher quality, more accessible, equitable and affordable, and to work within the US Department of Health and Human Services and with other partners to make sure that the evidence is understood and used.

AHRQ supported research into evidence-based hospital design, published in a special supplement of Health Environments Research & Design Journal. These studies concluded novel and best-practice technologies, materials, and design strategies may directly decrease the risk of transmission of pathogens by decreasing the burden of microorganisms in the environment. The role of copper was recognised: Alternative surface materials, such as copper alloys, provide continuous antimicrobial activity.

Green and Healthy Building Schemes

Finnish Building Information Foundation Indoor Hygiene  - General Criteria: RT1, 2017

Antimicrobial materials for high-touch surfaces are included as a measure to meet defined hygiene ratings for a variety of building types, including healthcare, education and food processing. Copper is recognised as the most effective and best known antimicrobial material.

See 4. Infection Control Indoors; 4.1 Surfaces, Fixtures and Fittings; 4.1.1 Antimicrobial Materials.

International WELL Building Standard™, 2016

The WELL Building Standard™ is an evidence-based system for measuring, certifying and monitoring the performance of building features that impact health and well-being. WELL is administered by the International WELL Building Institute™ (IWBI), a public benefit corporation whose mission is to improve human health and well-being through the built environment. It is third-party certified by Green Business Certification Inc which administers the Leadership in Energy and Environmental Design (LEED) programme.

Antimicrobial Copper meets the requirement of Section 27 Antimicrobial Activity for Surfaces - Part 1: High Touch Surfaces.

Antimicrobial surfaces (countertops and fixtures in bathrooms and kitchens, and all handles, doorknobs, light switches and elevator buttons) comprised of a material that is abrasion-resistant, non-leaching and meets EPA testing requirements for antimicrobial activity are an optimisation option.

IGBC Green Healthcare Facilities Rating System Guidelines, Pilot Version, 2016

In this Indian Green Building Council pilot scheme, copper surfaces approved by International Copper Association India comply with SH Credit 1: Sanitisation and Hygiene: Infection Control within the Spaces: Antibacterial Surfaces. High-touch surfaces for upgrade are listed as bed rails, telephones, toilet seats, toilet flush handles and inner washroom doorknobs, referencing the US Centers for Disease Control Environmental Checklist for Monitoring Terminal Cleaning.

Copper and copper alloys are engineering materials that are durable, colourful and recyclable and are widely available in various product forms suitable for a range of manufacturing purposes. Copper and its alloys offer a suite of materials for designers of functional, sustainable and cost-effective products.

Copper and certain copper alloys have intrinsic antimicrobial properties (so-called ‘Antimicrobial Copper’) and products made from these materials have an additional, secondary benefit of contributing to hygienic design. Products made from Antimicrobial Copper are a supplement to, not a substitute for standard infection control practices. It is essential that current hygiene practices are continued, including those related to the cleaning and disinfection of environmental surfaces.
