A pilot study comparing pattern of damage sustained among instruments from different surgical units in a tertiary care centre in Nepal - reappraising the role of instrument reprocessing in retaining their value

Development of a "Scissor-Tip-Separator" for adjustment of scissor blade separation and prevention of scissor blade damage during steam sterilization

Background

Reprocess reusable surgical instruments during steam sterilization; damage occurs to sharp scissor blades in close position, so steam cannot reach the blades. Surgical instruments' management requires standards to ensure patient safety and prevent harmful pathogens, especially in the COVID-19 pandemic. Although various devices can separate scissor blades, they do not prevent damage to cutting edges. To address the above problem, we developed a new scissor protector, the "Scissor-Tip-Separator," and evaluated its efficacy.

Methods

The "Scissor-Tip-Separator" design follows the steam sterilization guideline that instrument tips must be separated. The locking handles and V groove mechanism keep the scissor blades separated while preventing damage to the cutting edges. For efficacy assessment, purposive sampling was performed to select 44 Thai perioperative nurses at Ramathibodi Hospital, Bangkok, Thailand, to evaluate the "Scissor-Tip-Separators" in 450 sterile instrument containers. All participants evaluated surgical scissors placed in the "Scissor-Tip-Separators" during instrument setup, following a problem record checklist. At the end of the fifth use, participants were asked to complete the "Scissor-Tip-Separator" Effectiveness Scale, which was used to test the structural design of the "Scissor-Tip-Separator" in terms of function, usability, and safety. The Adenosine Triphosphate surface test was also used to validate the "Scissor-Tip-Separator" cleanliness. Data were collected from August 2020 to November 2020, then analyzed via descriptive statistics.

Results

The "Scissor-Tip-Separator" met the cleaning validation criteria, and in 44 uses, the physical property remained the same. The scissor shank was discovered loose from the handle before it had been unlocked (0.2–0.4%) at the 45^th use. Based on participants' opinions, the overall instrument effectiveness was high in terms of function, usability, and safety.

Conclusion

The "Scissor-Tip-Separator" regulates scissor blade separation under sterilization guidelines; it prevents damage to cutting edges, thus ensuring patient safety. It protects against losses in a sterile field and can prevent hand injuries.

Quality of water for reprocessing of medical devices in healthcare facilities in Nepal

Reusable medical devices are decontaminated and sterilized often many times by healthcare facilities across the globe. Reprocessing of medical devices comprises several processes and water plays an important role in some of these, including cleaning and steam sterilization. The water used is required to have certain qualities to ensure the effectiveness of the processes. In this short communication, we report findings of our study which measured quality parameters (pH, total hardness) for water used for medical device reprocessing in 13 primary and secondary care public hospitals in Nepal. The mean pH of water used for reprocessing of medical devices varied from 6.48 to 8.05 across the hospitals whereas the mean total hardness of water varied from 5.93 to 402.50 mg/L CaCO₃. Although the range of the mean water pH across hospitals fell within the recommended range, many of the hospitals had mean total hardness higher than recommended for cleaning medical devices. None of the hospitals had mean total hardness suitable for using as feed-water for steam generation. Public hospitals in Nepal should have appropriate water treatment systems so that the recommended water quality can be achieved to ensure effective decontamination and reprocessing of medical devices.

Sterile processing in low- and middle-income countries: an integrative review

BACKGROUND

Worldwide disparities in surgical capacity are a significant contributor to health inequalities. Safe surgery and infection prevention and control depend on effective sterile processing (SP) of surgical instruments; however, little is known about SP in low- and middle-income countries (LMICs), where surgical site infection is a major cause of postoperative morbidity and mortality.

AIM

To appraise and synthesise available evidence on SP in LMICs.

METHODS

An integrative review of research literature was conducted on SP in LMICs published between 2010 and 2020. Studies were appraised and synthesised to identify challenges and opportunities in practice and research.

RESULTS

Eighteen papers met the inclusion criteria for qualitative analysis. Challenges to advancing SP include limited available evidence, resource constraints and policy-practice gaps. Opportunities for advancing SP include tailored education and mentoring initiatives, emerging partnerships and networks that advance implementation guidelines and promote best practices, identifying innovative approaches to resource constraints, and designing and executing quality assurance and surveillance programmes.

DISCUSSION

Research investigating safe surgery, including SP, in LMICs is increasing. Further research and evidence are needed to confirm the generalisability of study findings and effectiveness of strategies to improve SP practice in LMICs. This review will help researchers and stakeholders identify opportunities to contribute. The burdens of unsafe surgery transcend geopolitical borders, and the global surgery and research communities are called upon to negotiate historical and present-day inequities to achieve safe surgery for all.
