Grading Gowns: Redesigning One-size PPE To Fit And Protect Female Health Workers More Effectively

Lead Research Organisation: Nottingham Trent University
Department Name: Sch of Art and Design

Abstract

Since the outbreak of COVID-19, a shortage of suitable PPE has resulted in healthcare workers(HCWs) wearing one-size, disposable isolation gowns, compromising comfort and safety. Oversized, ill-fitting gowns impede movement and increase body temperature and risk of viral transmission. Clinical procurement and acute care leads have expressed the need for more sustainable, reusable, individually sized PPE gowns fabricated from washable textiles to enhance the HCWs experiences, while mitigating infection risk and reducing clinical waste. The project will deliver a 'reusable PPE isolation gown system' including a doffing accessory to safely remove contaminated gowns. The healthcare sector ready set of gowns will be designed and produced in EN-certificated textiles and manufacturing conditions in multiple sizes (XS-XXXL) informed by: a systematic review of current PPE design, provision and use; qualitative data from interviews, questionnaires and wearer trials. The PPE outcomes will be disseminated via UK NHS trusts, health authorities, service conferences and publications. The investigators have industry/ research expertise in user-centred fashion and workwear design. Alexandra, is an industry leader in the production and supply of PPE gowns to UK health authorities and links with the Chelsea and Westminster NHS Foundation Trust. Other NHS partners include clinical procurement and acute care team leaders who have in-depth knowledge of the acquisition, distribution, use and affect of disposable PPE. The applicants' universities encompass the product design labs and resources required for fashion/ accessory development and prototyping. Alexandra will provide access to advanced clinical textiles, gown production and testing facilities. Interviews, questionnaires and wearer trials will facilitated via London, Northampton and Nottingham hospitals.

Title 'Cross-Contamination Gown' featured in , REPAIR Exhibition, PLATE Conference, Aalto University, 1-9 June 2023 
Description A selection of textile samples, full and half-scale garments created by repurposing used isolation gowns. I co-created an artefact entitled the Cross-Contamination Gown - a conceptual garment whereby sublimation printing and hand stitching were used to simulate viruses and damage. The other artefacts featured in the 'PPE Repurposing: Workshop oucomes 1' exhibit, were crafted by undergraduate student and teaching staff from the Fashion, Textile and Knitwear department at Nottingham Trent University. Embroidery, weave, print and knitting techniques were explored alongside zero waste pattern cutting techniques to develop innovative fabrics and garments.

Acceptance by these conferences evidences a shift in perceptions sustainable fashion practice, by embracing research into circular PPE product approaches, not traditionally considered as part of fashion/ design. 
 
Description Achievements
The most significant achievement of the research is a market-ready multi-sized Reusable Gown System (XS-5XL) suitable for use as a PPE isolation or surgeons' gown, encompassing improved wearer comfort, fit and safety compared to single use (and some reusable) products. The identified benefits of the gown include: enhanced comfort and fit; preferred by clinical teams; higher quality and performance against standards; lower overall cost than single-use products; more resilient supply; less storage requirement; decreased environmental impact; supports local economies. The design and fabrication of the gowns was informed by fulfilling the following objectives, leading to, or corroborating key findings.

Surveying healthcare workers
While this objective was challenging during and post-pandemic, an online questionnaire completed by 130 nursing staff - mainly from the East Midlands - confirmed that 75% were wearing disposable gowns in one-size, L and XL, causing different levels of discomfort, safety and performance issues, particularly for individuals with petite, ectomorphic or tall, endomorphic bodies. Analysis of the surveyed participants' narrative comments provided compelling evidence relating to how: wearing oversized impeded actions during medical procedures, risking accidents (e.g. tripping over); gaping backs, loose and tight necklines and cuffs presented comfort and safety risks; heat stress was explicitly linked to oversized garment volumes and plastic-based fabrication - all of which have the capacity to detrimentally impact patient care. An unexpected finding was the desire by NHS staff to be sustainable and concern about the amount of PPE waste being generated.
Gown Review
Our objective of undertaking a review of 30 single use and reusable gowns on the market resulted in findings that corroborated the generic 'one-size fits all' approach of single-use products and the lack of bespoke sizing (and shaping) options to meet the contrasting physiologies associated with the 75%+ of women who make up the NHS workforce, many from different ethnic backgrounds.

By documenting the specifications of 12 physical samples we were able to cross-reference the findings from the survey and interviews with medical team leads. By trying the gowns on we were able to understand how poorly designed/ placed neck and waist fastenings made donning and doffing difficult; the lack of flexibility of elasticated cuffs and thermal discomfort caused by composite and plastic (PU) coated fabrics; the desire by healthcare workers to be sustainable.

The most significant issue highlighted, apart from sizing, was the heat inducing properties of the synthetic textiles the gowns are fabricated in. To mitigate this in our redesign, we sourced specialist PPE textiles from a locally based international textile manufacturer to improve the thermal comfort of wearers. Wearer trials of more than 500 gowns by five NHS trusts confirmed that the fluorocarbon coated breathable polyester textiles are more comfortable to wear and easier to launder than plastic (PU) coated reusable products.

A related finding was that reusable PPE isolation gowns are based on the design surgeons' gowns and as traditionally more surgeons are men, the sizing and shaping relates to male physiology and associated dimensions. The main difference between reusable PPE and surgeons' gowns is the decontamination and sterilising requirements, which influenced our decision to design and market the gown for both contexts.

Procurement and Servicing Infrastructure
A significant barrier to the procurement of reusable PPE during the COVID-19 pandemic was the lack of a documented network of UK manufacturers, the fragmented nature of the NHS supply chain and government's resistance to support on-shore production. SME's with established experience of making (and servicing) reusable surgeons gowns and other medical apparel and textiles were overlooked by the VIP Lane despite lobbying their MPs (e.g. in Sutton-in-Ashfield). This led to many companies with no, or limited experience of manufacturing PPE being awarded large contracts to effectively import single-use products, as reported in the COVID Enquiry and beyond.

Another significant barrier to healthcare organisations adopting reusable PPE (during and post-COVID) is the lack of hospital laundries, most of which have been closed. While there are medical laundry providers, many of whom are members of the Textile Services Association (TSA) there are still gaps in the market. In response RevolutionZERO have designed a cost-effective modular alternative. The all-electric decontamination hub that be placed close to healthcare facilities avoiding transport costs and improving supply resilience, reducing the carbon footprint of both the process and logistics.
Exploitation Route In addition to marketing the Anze.NTU,RevolutionZERO reusable product/service ourselves, we envisage that the system could be taken up by the NHS and other healthcare providers across the UK. In comparison with other products on the market, our reusable gown represents a medical product that surpasses EN1379 quality standards by offering high level protection, flexible fit and thermal comfort, in acknowledgement of the ethnicity, diversity and inclusivity of the workforce and their environments.

The successful implementation of the system could inform a national (four nations) procurement policy supported by the Department for Health and Social Care to help reduce the carbon footprint of PPE in alignment with Net Zero/ Greener NHS targets by replacing the model of importing up to 80% of PPE from offshore. Mapping a national infrastructure of reusable PPE providers could highlight geographical gaps in supply and investment in key regions linked to the UK Government's Levelling Up initiative.

Circularity
Our Reusable PPE/Surgeons' Gown has been designed within a Circular System incorporating design, servicing, re-use and recycling. With further research and development this, or a similar 'system' focused on enhancing user/patient safety and experience while extending product lifetimes the has the capacity to revolutionise the sustainability of the PPE supply chain.

In developing the reusable gown we have assembled a local supply chain comprising a textile mill, gown manufacturer and decontamination service to support the local/ regional network required to develop a redistributed manufacturing (RDM) and circular economy (CE) model.

Research into repurposing the gowns at end of their first life (75 uses) is ongoing through a range of potential initiatives and spin-outs with partners in education, industry and the third sector.

Description Emerging Impact The research team have developed a reusable PPE/Surgeons' isolation gown in collaboration with industry and NHS partners. The contribution of our research has been acknowledged in the labelling of the gown as: Anze.NTU.RevolutionZERO. The reusable gown, produced in sizes XS-5XL and fabricated in polyester/carbon graft, has been deemed to be better fitting, more comfortable and cooler to wear than single-use and (some) other reusable gowns, by 70 participants in wearer trials of over 500 gowns. These include doctors and nursing staff treating patients with COVID-19, its variants, other contagious viruses or surgical contexts where cross-contamination could occur (e.g. hip replacement operations). The Reusable PPE Gown System is due to be launched commercially in July 2024 at the Mansfield Hub, Nottingham Trent University. Once launched the gown will replace all the current reusable PPE/Surgeons' gowns sold by Anze (n=5,000 per annum) and further orders will be sought which in time, representing societal benefits for the healthcare industry and the environment and potential economic growth for the gown manufacturers who are based in a designated 'levelling up' area of the East Midlands. The gown system is supported by a circular model and take-back scheme, devised to extend the lifetime of the reusable gown (and its constituent materials) through three additional phases of reuse. Reuse Phase 1 involves up to 75 wash (decontamination) and wears by healthcare workers. The three further stages of reuse are still being developed in the following contexts. In Reuse Phase 2 gowns will be customized for patient care (e.g. colonoscopy); Reuse Phase 3 will focus on utilising the polyester materials within upcycled fashion and textile contexts; Reuse Phase 4 represents the ultimate recycling phase whereby the resulting materials will be melted down, extruded and re-spun as polyester yarn to be woven into new reusable gowns. Challenges There are numerous challenges involved in developing a fully circular reusable gown model because the current PPE procurement, use and disposal model is generally based on offshore production and disposal via incineration (for single use) or landfill/ offshore (for reusable). We have devised a distributed local and national network to produce and service the Anze.NTU.RevolutionZERO reusable gown. We now need to design routes for reuse of the PPE material waste stream, requiring new services and skills development involving the collection, storage and redirection of used garments to partner organisations who can customize, deconstruct, upcycle and recycle the polyester textiles. Design Education We have raised awareness of the user and environment- centred benefits for designing and recycling reusable PPE isolation gowns by engaging with commercial designers and undergraduate and postgraduate students and staff from the Fashion, Textile and Knitwear department at Nottingham Trent University and at the University of Maribor, Slovenia in repurposing workshops and exhibitions. We plan to tour the PPE Refashioned exhibition in the UK (possibly EU universities) and have approached the Royal College of Nursing and Wellcome Trust as potential venues.

Title Online questionnaire 
Description We designed an illustrated, anonymous Online Research Questionnaire directed at healthcare workers to gain first hand insights into issues experienced when wearing isolation gowns, as it was impossible to interview them during the COVID-19 pandemic and beyond. Questions were based on findings from the literature and gown review. 
Type Of Material Improvements to research infrastructure

Provided To Others? Yes  
Impact The questionnaire enabled participants from healthcare organisations to candidly state the issues experienced with the gowns procured for them and describe how these products could be enhanced. At present most nurses have limited say in the design, fabrication or size of the gowns they are issued with despite well publicised problems associated with the generic supply of one-size, L or XL products. Space for additional comments reflected the desire for staff to have a wider choice of sizes, breathable fabrics and reusable styles to improve person-centred and environmental sustainability.
