Reprocessing Standards for Medical Devices and Equipment in Otolaryngology: Safe Practices for Scopes, Speculums, and Single-Use Devices

Complications Associated with AMBU™ Scope Use: An FDA MAUDE Analysis

Ambu® aScope™ is a disposable flexible videoscope used for a wide range of medical procedures. However, adverse events associated with this device can occur. The Food and Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database was explored for patient-related adverse events associated with Ambu® aScope™ use between January 1, 2000 and December 15, 2023. Search terms included "Ambu" and "Ascope." Thirty unique adverse events were identified. Twenty-one of the events were associated with patient injury, and 9 with device malfunction. Eight patient-reported problems were documented as foreign bodies, 3 events as airway obstruction, desaturation, or hypoxic events, and 1 event as anxiety/cardiac arrest. The remaining 18 reported insufficient information other than associated with patient injury. We found that Ambu® aScope™ flexible nasolaryngoscopes and bronchoscopes are a common and effective tool for airway evaluations that may infrequently serve as a rare form of foreign body with potentially life-threatening consequences.

Sustainable equipment donation in otolaryngology in low-resource settings

PURPOSE OF REVIEW

The purpose of this review is to examine current practices in surgical equipment donation to lower- and middle-income countries (LMICs) with a particular focus on otolaryngology-head and neck surgery (OHNS). This is designed as a pragmatic review to guide potential donor communities to implement sustainable OHNS equipment donation in LMICs.

RECENT FINDINGS

LMICs are increasingly reliant on international equipment donation. In terms of OHNS services, global OHNS have compiled a list of essential equipment for baseline care in LMICs. Especially in terms of audiology, OHNS equipment donation has the potential to have a significant impact on populational health. However, there is a scarcity of research on donated equipment in OHNS. A suggested blueprint for sustainable equipment donation follows these steps: establish partnerships, assess needs, source equipment, and follow-up and evaluate the intervention. Key further considerations for sustainability include remanufacturing and repurposing methods, maintenance, and contextual understanding.

SUMMARY

Sustainable equipment donation in otolaryngology is an important part of global health equity and healthcare delivery in low-resource settings. Despite the good intentions behind medical equipment donations, there are many challenges; donors and recipients should engage in collaborative, needs-based planning processes that result in long-term sustainability, local capacity building, and community participation.

Carbon Neutral Hand Surgery: Simple Changes to Reduce Carbon Footprint

Introduction: Rapid climate change poses a major challenge to healthcare. The operating room is especially responsible for carbon emission, with 20% to 70% of hospital waste traced back to the operating room. This literature review aims to suggest changes that can be made in hand surgery for a more sustainable practice. Methods: A literature search was conducted from PubMed, Medline, and other online search engines with the keywords "carbon footprint, environmental health, carbon neutral, plastic surgery, hand surgery, surgery." Results: "Reduce, Reuse, Recycle, Research, Rethink and Culture" was the framework used to recommend a more carbon neutral practice. In reduction, techniques such as cutting down oversupply of materials, adopting protocols to perform cases in ambulatory settings, and simple measures to reduce energy were identified as valuable methods. Modified sterilization techniques and reprocessing single-use devices were techniques identified for reuse and recycling involved single-stream recycling, staff training, and donation of basic surgical supplies. Research involved adopting data-driven programs for life cycle assessment of all equipment in the operating room, while the use of telemedicine and "green meetings' were suggested for rethinking. Finally, strategies to encourage a team approach to environmental responsibility were discussed. Conclusion: Carbon neutral practice must be implemented to safeguard sustainable and cost-effective operating rooms and healthcare systems. Hand surgery can pave the way for other specialties through the use of available resources to develop guidelines for carbon neutral practice. This requires active effort from hand surgeons to act as role models for other healthcare professionals.

Remanufacturing of single-use medical devices: a case study on cross-border collaboration between the UK and Nigeria

This paper aims to evaluate the current state of the remanufacturing of medical devices, considering the differences between developed and developing countries. With reference to various socio-economic factors, the impact of remanufacturing to sustainability was evaluated and from this, single-use medical devices were deemed to be critical in minimising waste within the medical industry. This is even more critical with increasing use of single-use devices in the Coronavirus disease 2019 (COVID 19) pandemic. It was identified that cleaning is a key consideration for ensuring a safe remanufacturing process that would minimise the risk of infection to patients. Therefore, this process was evaluated and appropriate recommendations made. Although there may be some challenges, further research would be required for integration of the methodology and process outlined into the medical sector.
