Does the type of surgical drape (disposable versus non-disposable) affect the risk of subsequent surgical site infection?

Handling 'carbon footprint' in orthopaedics

INTRODUCTION

The National Health Service contributes 4%-5% of England and Wales' greenhouse gases and a quarter of all public sector waste. Between 20% and 33% of healthcare waste originates from a hospital's operating room, and up to 90% of waste is sent for costly and unneeded hazardous waste processing. The goal of this study was to quantify the amount and type of waste produced during a selection of common trauma and elective orthopaedic operations, and to calculate the carbon footprint of processing the waste.

METHODS

Waste generated for both elective and trauma procedures was separated primarily into clean and contaminated, paper or plastic, and then weighed. The annual carbon footprint for each operation at each site was subsequently calculated.

RESULTS

Elective procedures can generate up to 16.5kg of plastic waste per procedure. Practices such as double-draping the patient contribute to increasing the quantity of waste. Over the procedures analysed, the mean total plastic waste at the hospital sites varied from 6 to 12kg. One hospital site undertook a pilot of switching disposable gowns for reusable ones with a subsequent reduction of 66% in the carbon footprint and a cost saving of £13,483.89.

CONCLUSIONS

This study sheds new light on the environmental impact of waste produced during trauma and elective orthopaedic procedures. Mitigating the environmental impact of the operating room requires a collective drive for a culture change to sustainability and social responsibility. Each clinician can have an impact upon the carbon footprint of their operating theatre.

Reuse of Orthopaedic Equipment: Barriers and Opportunities

» Reuse of orthopaedic equipment is one of many potential ways to minimize the negative impact of used equipment on the environment, rising healthcare costs and disparities in access to surgical care.» Barriers to widespread adoption of reuse include concerns for patient safety, exposure to unknown liability risks, negative public perceptions, and logistical barriers such as limited availability of infrastructure and quality control metrics.» Some low- and middle-income countries have existing models of equipment reuse that can be adapted through reverse innovation to high-income countries such as the United States.» Further research should be conducted to examine the safety and efficacy of reusing various orthopaedic equipment, so that standardized guidelines for reuse can be established.

The carbon footprint of arthroscopic procedures

INTRODUCTION

The healthcare sector contributes the equivalent of 4.4% of global net emissions to the climate carbon footprint; between 20% and 70% of healthcare waste originates from a hospital's operating theatre and up to 90% of waste is sent for costly and unneeded hazardous waste processing. This study aimed to quantify the amount and type of waste produced during an arthroscopic anterior cruciate ligament reconstruction (ACLR) and an arthroscopic rotator cuff repair (RCR), calculate the carbon footprint and assess the cost of the waste disposal.

METHODS

The amount of waste generated from ACLR and RCR procedures was calculated across a range of hospital sites. The waste was separated primarily into clean and contaminated, paper or plastic. Both carbon footprint and cost of disposal across the hospital sites was subsequently calculated.

RESULTS

RCR generated 3.3-15.5kg of plastic waste and 0.9-2.3kg of paper waste. ACLR generated 2.4-9.6kg of plastic waste and 1.1-1.6kg of paper waste. The cost to process waste varies widely between hospital sites, waste disposal contractors and method of waste disposal. The annual burden of the included hospital sites for the arthroscopic procedures undertaken was 6.2 tonnes of carbon dioxide.

CONCLUSIONS

The data collected demonstrated a significant variability in waste production and cost for waste disposal between hospital sites. At a national level, consideration should be given to the procurement of appropriate products such that waste can be efficiently recycled or disposed of by environmentally sustainable methods.

Sustainability studies in orthopaedic surgery: The carbon footprint of anterior cruciate ligament reconstruction depends on graft choice

PURPOSE

Environmental sustainability in medicine is a growing concern. Determining the carbon footprint of medical procedures may aid in selecting a less impactful technique moving forward. The purpose of this study was to understand the environmental impact of different anterior cruciate ligament reconstruction techniques, for which there is no consensus in terms of optimal graft.

METHODS

A life cycle analysis of different anterior cruciate ligament reconstruction techniques was performed. These included quadrupled semitendinosus graft, bone-patellar tendon-bone graft, iliotibial band augmented with gracilis graft, doubled semitendinosus and doubled gracilis graft, and quadriceps tendon graft. All procedures were systematically paired with a lateral extra-articular procedure. The study was conducted in a specialised centre using surgeon preference cards, with the help of a dedicated organisation for calculation according to the ISO 14044 standard. The primary outcome measure was the carbon footprint of each of the five techniques. Secondary outcomes included other environmental impact indicators, including human carcinogenic toxicity and mineral resource scarcity, among others, based on the ReCiPe 2016 midpoint guideline. The analysis had three scopes, each encompassing varying numbers of processes: graft implantation, full procedure, and entire environmental impact, from medical prescription to patient discharge. Results were reported as percentage increases compared to the graft technique with the lowest environmental impact.

RESULTS

It was demonstrated that the surgical procedure itself accounted for <40% of the life cycle, with arthroscopy being 88% of surgery's GHG emissions, and scrubbing and draping contributing 39% to the carbon footprint. The iliotibial band augmented with gracilis tendon technique had the lowest carbon footprint (0.199 Kg Co2 eq), and the least impact in most categories at all scopes of the life cycle analysis. Using this technique as a reference, in terms of graft implantation, it was determined that extensor mechanism grafts had the highest carbon footprint (300% higher than the reference). Greater scopes showed a similar trend, with percentage differences decreasing significantly, reaching 1-3% when considering the entire environmental impact for most categories. Nevertheless, among the aforementioned factors of the ReCiPe 2016 guidelines, the semitendinosus graft paried with a lateral extra-articular procedure displayed greater difference in human carcinogenic toxicity and mineral resource scarcity (6% and 10% respectively) compared to the reference. The individual processes with the highest impact were also highlighted.

CONCLUSIONS

In the institution where the study was conducted, the studied iliotibial band graft option was found to have the lowest environmental impact. Such analyses of standardised procedures can be replicated in individual institutions in order to determine their environmental impact. Identification of procedures with comparable results and differing environmental consequences may influence the future decision-making process.

Reusing sterile cotton fabric barriers in the clinical practice: an observational and longitudinal study

OBJECTIVE

to analyze the physical and biological barrier characteristics of cotton fields used as a sterile barrier system after multiple use and processing cycles in the clinical practice.

METHOD

an observational and longitudinal study to monitor and evaluate 100% cotton fabric used as a sterile barrier system in a medium-sized hospital. Samples were collected before use (after three washes) and at three, six, nine, 12 and 15 months of use and evaluated for the number, thickness and integrity of threads, weight, water absorption and wet penetration by microorganisms.

RESULTS

after 85 washes, the number of threads remained unchanged, and the shredded fibers and the water volume absorbed were increased. The microbiological test using the German standard methodology obtained a negative result and wet penetration by microorganisms did not show significant changes over time, although a percentage of the microbial cells passed through the double-layer samples.

CONCLUSION

the physical properties of 100% cotton used as a sterile barrier system changed with use/processing cycles; however, these alterations did not significantly interfere with the results obtained by the tests performed on the microbiological barrier up to 85 washes. (1) Clinical use and processing exert an impact on the sterile fabric barrier system. (2) There was weight loss, reduction in size and increase in water absorption volume. (3) The longer the use, the more loose fibers. (4) Penetration by microorganisms did not increase over the 15 months of the study. (5) The physical changes of the fabric did not interfere with the fabric barrier efficiency.

Sustainable surgical practices: A comprehensive approach to reducing environmental impact

This paper presents a comprehensive overview of the environmental impact of surgical procedures and highlights potential strategies to reduce the associated greenhouse gas emissions. We discuss procurement, waste management, and energy consumption, providing examples of successful interventions in each area. We also emphasize the importance of adopting the Green Theatre Checklist as a useful tool for clinicians aiming to implement sustainable surgical practices.

Sustainable orthopaedic surgery: Initiatives to improve our environmental, social and economic impact

In response to appeals from the WHO and The Lancet, a collaborative statement from over 200 medical journals was published in September 2021, advising international governments to combat the "catastrophic harm to health" from climate change. Healthcare, specifically surgery, constitutes a major contributor to environmental harm that remains unaddressed. This article provides practical guidance that can be instituted at a departmental, hospital and national level to institute transformative, sustainable efforts into practice. We also aim to provoke healthcare leaders to discuss policy-making with respect to this issue and highlight the necessity for sustainability to become a core domain of quality improvement. The average orthopaedic service produces 60% more waste than any other surgical specialty. Fortunately, simple measures such as a comprehensive education programme can decrease waste disposal costs by 20-fold. Other simple and effective "green" measures include integrating carbon literacy into surgical training, prioritising regional anaesthesia and conducting recycling audits. Furthermore, industry must take accountability and be incentivised to limit the use of single-item packaging and single-use items. National policymakers should consider the benefits of reusable implants, reusable surgical drapes and refurbishing crutches as these are proven cost and climate-effective interventions. It is crucial to establish a local sustainability committee to maintain these interventions and to bridge the gap between clinicians, industry and policymakers.

The Environmental Impact of Spine Surgery and the Path to Sustainability

STUDY DESIGN

Narrative literature review.

OBJECTIVE

The aim of this study was to review published literature discussing sustainable health care and to identify aspects that pertain to spine surgery.

SUMMARY OF BACKGROUND DATA

In recent years, research has investigated the contribution of surgical specialties to climate change. To our knowledge, no article has yet been published discussing the impact specific to spinal procedures and possible mitigation strategies.

METHODS

A literature search was performed for the present study on relevant terms across four electronic databases. References of included studies were also investigated.

RESULTS

Spine surgery has a growing environmental impact. Investigations of analogous specialties find that procurement is the single largest source of emissions. Carbon-conscious procurement strategies will be needed to mitigate this fully, but clinicians can best reduce their impact by adopting a minimalist approach when using surgical items. Reduced wastage of disposable goods and increased recycling are beneficial. Technology can aid remote access to clinicians, and also enable patient education.

CONCLUSIONS

Spine-surgery-specific research is warranted to evaluate its carbon footprint. A broad range of measures is recommended from preventative medicine to preoperative, intraoperative, and postoperative spine care.

Novel Designed Surgical Drapes Reducing Fluid Permeability in the Surgical Critical Area of a Sterile Operation Interface: A Randomized Controlled Trial

Aim. To compare the impact and cost effects of medical long fiber polyester drapes and cotton fabric drapes on operative sterile operation interfaces. Background. The comparison of the properties of the commonly used surgical drapes materials in terms of leakage, device slip, and prevention of intraoperative adverse events is not clear. Method. A prospective randomized controlled study was conducted in the operating room of a tertiary hospital in Chengdu, China. A total of 400 patients who underwent urology surgery were enrolled and randomly divided into two groups by computer, the study group (200 cases) selected the new long-fiber polyester cloth, while the control group (200 cases) selected conventional cotton fabric surgical drapes during the operation to maintain a sterile operating interface. The impermeability and water absorption of surgical drapes, the rate of device slip and skin scald in surgical patients, and the cost effect of the two kinds of surgical drapes were compared. Results. The long fiber polyester surgical drapes were superior to conventional cotton cloth in water absorption (g/m2) (835 ± 15.8 VS 225 ± 21.0, t = 328.261, $P<0.001$ ), preventing surgical site infections (2.5% VS 8.0%, χ2 = 6.081, $P=0.014$ ), device slip (7.5% VS 17.0%, χ2 = 8.396, $P=0.004$ ), patients from burning (0 VS 1, Fisher $P=1.0$ ), and total cost per use ($) (0.83 VS 0.96–1.09). Conclusion. Long fiber polyester fabric has a stronger antipenetration ability of fluid and microorganisms thus forming an effective protective barrier. It also has strong hygroscopicity, and its special design can prevent the occurrence of sliding of surface instruments and skin scald in patients. In addition, its cost effect is superior. Implications for Nursing Management. Operating room nursing managers can introduce long fiber polyester drapes into the selection of medical textiles to construct aseptic surgical barriers and prevent surgical site infection.

Perspectives of vets on plastics in veterinary medicine

INTRODUCTION

The use of disposable plastics and their subsequent environmental impacts are topics of increasing concern in modern society. Medical, including veterinary, sectors are major contributors to plastic waste production. While there is an existing body of literature on the use and reduction of disposable plastics in the human medical sector, few studies, if any, have specifically investigated the use of plastics within the veterinary field. The overall aim of this pilot study was to investigate Australian veterinarians regarding their attitudes toward the ways in which they use disposable plastic in their work and personal lives.

MATERIALS AND METHODS

Seven veterinarians were interviewed, representing a range of demographics and professional backgrounds from multiple states. Thematic qualitative analysis was employed to organise the data into several major themes encompassing many smaller nodes.

RESULTS

The dataset revealed that most, if not all, veterinarians interviewed agree that disposable plastic is used in excess in veterinary medicine, but that veterinarians will never be able to avoid using plastic entirely. Participants supplied differing opinions with respect to the best strategies for reducing plastic waste production within the veterinary field, including recycling, replacing disposable items or improving education.

DISCUSSION

Despite different participants suggesting conflicting ideas, most, if not all, of the ideas presented have support in the scientific literature. This supports a hybrid approach involving refining recycling systems, reducing plastic consumption and improving education on plastic waste production. A hybrid top-down-bottom-up approach must include encouraging cooperation among stakeholders, both within and outside the veterinary sector, as this will be a major contributor to progress. In a broader context, this hybrid approach to inciting change at all levels of the veterinary sector will require engagement from many interdependent entities; as such, this study should act as a starting point for an ongoing process of cooperative change. Recommendations for future research include life cycle analyses of reusable versus disposable veterinary materials; exploring ways to expand sustainability education within and beyond the veterinary sector, and examining methods of improving technology and infrastructure.

Environmental sustainability in orthopaedic surgery

Aims

In the UK, the NHS generates an estimated 25 megatonnes of carbon dioxide equivalents (4% to 5% of the nation’s total carbon emissions) and produces over 500,000 tonnes of waste annually. There is limited evidence demonstrating the principles of sustainability and its benefits within orthopaedic surgery. The primary aim of this study was to analyze the environmental impact of orthopaedic surgery and the environmentally sustainable initiatives undertaken to address this. The secondary aim of this study was to describe the barriers to making sustainable changes within orthopaedic surgery.

Methods

A literature search was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines through EMBASE, Medline, and PubMed libraries using two domains of terms: “orthopaedic surgery” and “environmental sustainability”.

Results

A total of 13 studies were included in the final analysis. All papers studied the environmental impact of orthopaedic surgery in one of three areas: waste management, resource consumption, and carbon emissions. Waste segregation was a prevalent issue and described by nine studies, with up to 74.4% of hazardous waste being generated. Of this, six studies reported recycling waste and up to 43.9% of waste per procedure was recyclable. Large joint arthroplasties generated the highest amount of recyclable waste per procedure. Three studies investigated carbon emissions from intraoperative consumables, sterilization methods, and through the use of telemedicine. One study investigated water wastage and demonstrated that simple changes to practice can reduce water consumption by up to 63%. The two most common barriers to implementing environmentally sustainable changes identified across the studies was a lack of appropriate infrastructure and lack of education and training.

Conclusion

Environmental sustainability in orthopaedic surgery is a growing area with a wide potential for meaningful change. Further research to cumulatively study the carbon footprint of orthopaedic surgery and the wider impact of environmentally sustainable changes is necessary.
