Embracing Sustainability in Healthcare: The Change to Reusable Surgical Caps

In the pursuit of greener healthcare practices, trauma orthopaedics at Somerset has taken a significant step towards sustainability. They are replacing single-use surgical caps with reusable alternatives. This move aligns with the NHS Green Plan and brings substantial cost and environmental benefits. It also enhances communication for patients and staff, leading to improved patient safety.

The Power of Change across Healthcare Trusts

This impactful initiative is not limited to just one hospital. All healthcare trusts can adopt this change and reap the many benefits it brings. By making this transition, hospitals across the UK can take a proactive role in advancing sustainability, improving patient care, and enhancing operational efficiency.

Cost Efficiency Over Three Years

Previously, orthopaedic theatres (three in total) used 19,550 disposable caps per year. By transitioning to 424 reusable caps, along with 84 name badges, the department has significantly reduced expenses:

• Disposable caps cost: £8,211 over three years.
• Reusable caps cost: £4,099 + £243.60 (name badges) = £4,342.60 over three years.
• Total savings: £3,868.40.
  
  

(These are projected savings based on available figures, which will be confirmed with hard data post-implementation.)

The savings illustrate how hospitals can reduce costs simply by rethinking everyday practices. However, these figures are conservative. Reusable caps have proven to last far beyond initial estimates. Our very first customer, Dr. Diwan, who wrote this case study, still wears her reusable hats from 2021, more than four years ago. This longevity means the financial savings and CO2 reductions identified in this study are likely underestimated, making the transition even more beneficial in the long run.

Environmental Impact of Reusable Caps

Considering the life cycle assessment of both disposable and reusable caps, the carbon footprint of reusable caps is initially higher but significantly lower over time.

• Annual carbon emissions from single-use caps: 2,688.1 kg CO2e.
• Annual emissions from reusable caps: 975.2 kg CO2e.
• Total carbon saved per year: 1,712.9 kg CO2e.
  
  

These figures are based on a small department with only three theatres. When scaled across an entire trust, the savings in both cost and environmental impact will most likely quadruple. This makes the transition an even more compelling step toward sustainable healthcare.

Reusable caps reach their carbon break-even point after just 18 washes. This means every subsequent use results in net environmental savings. Given that reusable caps have been worn for four years and counting, the long-term environmental benefits are even greater than initially projected.

Enhancing Communication & Patient Safety

Beyond financial and environmental benefits, the introduction of badge hats significantly improves communication in operating theatres, radiology, Cath labs, and maternity. Traditionally, these teams wear identical disposable caps. This makes it difficult to identify colleagues during critical procedures.

By incorporating name badges into reusable caps, staff can quickly and efficiently communicate. This improvement enhances workflow and collaboration.

Additionally, better identification enhances patient safety, reducing errors and ensuring seamless coordination among surgical teams. Clearer communication leads to a more effective and efficient operating environment, benefiting both patients and healthcare professionals alike.

The Path Forward for Sustainable Practices

With no increase in surgical site infections observed from reusable caps, this project demonstrates a practical and low-burden transition to greener surgical practices. Given the financial, ecological, and communication advantages, expanding the use of reusable badge hats across all surgical units is a logical next step towards a more sustainable and effective healthcare system.

By making this simple yet impactful switch, operating theatres, radiology departments, cardiac catheter labs, and maternity departments across all NHS trusts can champion eco-friendly innovation. They can improve communication in clinical settings and enhance patient safety while maintaining cost efficiency.
