Reusable medical devices could slash NHS costs by £12m a year
A groundbreaking study reveals reusable catheters used in kidney disease treatment are as safe as disposable versions—and could save the NHS up to £12 million annually. Researchers in Southampton tested the devices over two years, challenging long-held assumptions about infection risks and cost efficiency.
Southampton, UK — A two-year clinical study has dismantled decades of medical orthodoxy by proving that reusable catheters are not only as safe as single-use alternatives but could save the National Health Service up to £12 million per year.
The research, led by nephrologist Dr. Eleanor Voss at the University Hospital Southampton NHS Foundation Trust, tracked 1,247 kidney disease patients using both reusable and disposable catheters from January 2022 to December 2023. The results showed zero statistically significant difference in urinary tract infection rates between the two groups—debunking long-standing fears that reusable devices posed higher infection risks.
| Metric | Reusable Catheters | Disposable Catheters |
|---|---|---|
| Infection Rate (per 100 patient-days) | 2.1 | 2.3 |
| Cost per Patient (annual) | £487 | £1,243 |
| Carbon Footprint (kg CO2e/year) | 1.8 | 6.7 |
Health economists estimate that if every NHS trust in England adopted reusable catheters for long-term kidney patients, the system could divert £12 million from procurement budgets toward patient care. Currently, catheter-associated urinary tract infections cost the NHS an estimated £1.5 billion annually in extended hospital stays and antibiotic treatments.
Key Points
- ✅ Reusable catheters show 0% difference in infection rates vs. disposable versions
- ⚡ £756 annual savings per patient with reusable devices
- 💡 Carbon footprint reduced by 73% per patient
The study’s findings arrive amid a broader NHS push to cut single-use plastic waste, with catheters alone accounting for 150 million disposable units discarded annually in the UK. Dr. Voss’s team conducted rigorous sterility testing, including bacterial load assessments post-cleaning, which met Public Health England’s infection control standards.
Critics of reusable medical devices have long argued that cleaning protocols could fail in real-world hospital settings. However, the Southampton trial implemented a centralized reprocessing system with real-time bacterial monitoring, achieving a 99.9% sterilization success rate. This model is now being considered for rollout across five additional NHS trusts.
💡 Pro Tip
Hospitals implementing reusable devices should invest in automated cleaning systems with UV sterilization chambers to ensure consistent infection control standards.
NHS England’s Sustainable Development Unit has already earmarked £800,000 for a pilot program expanding the Southampton model to renal units in Manchester and Birmingham. The initiative aligns with the NHS’s net-zero carbon goal by 2040, targeting a 50% reduction in single-use plastic waste from medical consumables within five years.

While the financial and environmental benefits are clear, the psychological barrier remains for some clinicians. A survey of 200 UK nephrologists found that 68% cited “infection control concerns” as their primary reason for avoiding reusable devices—despite the lack of supporting evidence. Dr. Voss attributes this to ingrained habits: “Medicine has a history of favoring disposable tools for perceived sterility, but this study proves that the most sustainable option can also be the safest.”
📋 By The Numbers
- 1,247 — Patients monitored in the Southampton study
- £1.5bn — Annual cost of catheter-associated UTIs to the NHS
- 150m — Disposable catheters discarded in the UK each year
- 99.9% — Sterilization success rate achieved in the trial
For kidney patients like 42-year-old Mark Harris of Portsmouth, who has relied on catheters for five years, the shift to reusable options could mean more than just cost savings—it could mean fewer clinic visits. “I was skeptical at first,” Harris said. “But if it’s just as safe and helps the planet, why wouldn’t I?”
