Human Papillomavirus (HPV)
Risk and Challenges
UV-C High Level Disinfection
is Effective Against HPV
The aim of this study was to determine if UV-C disinfection is efficient in routine clinical conditions, especially against HPV. 1
The study also aimed to compare two protocols usually found in infection prevention practice of endocavity ultrasound probes. The simple protocol consisted of performing LLD with a chemically impregnated wipe on a probe used with a disposable cover. The more rigorous protocol consisted of performing HLD on a visibly clean probe.
The three-step study evaluated ultraviolet-C (UV-C) efficacy against human papillomavirus (HPV) found on vaginal ultrasound probes.
The first two steps evaluated UV-C disinfection of vaginal ultrasound probes.
Overview
The study took place in a high-turnover gynaecological practice (12,000 emergency consultations with 8,000 vaginal ultrasound examinations annually) in a specialized university hospital.
- It was the first to evaluate UV-C disinfection efficacy against HPV in real conditions when the UV-C system is run within a short time cycle (90 seconds).
- The results of this study indicated that UV-C can be used to ensure patient safety during ultrasound examinations.
- The second and third parts confirmed that the LLD procedure alone is unsafe when compared to HLD method such as UV-C that can reliably inactivate HPV. This method is strongly recommended to ensure patient safety.
- The study demonstrated the benefit of using the UV-C system: easy to use, effective, safe to the user, and faster than other decontamination systems.
- The study highlighted the need for standardised solutions that include HPV
Conclusion
UV-C has been confirmed as a relevant and easily adaptable solution to the healthcare environment. 1
