A new checklist surgical hand scrub to replace time-based methods – A pixel intensity analysis
Background
Hand scrubbing is an absolute precaution to avoid surgical site infections. World Health Organization (WHO) recommends 4-min overall scrubbing (4MS) for surgical hand hygiene. However, we hypothesize that the more methodical 10-stroke counting technique (10SS) via locational partitioning of the arm is superior to WHO's superficial guideline dictating only the duration.
Purpose
The mechanical efficiency of 4MS and 10SS techniques are compared.
Methods
24 healthcare professionals were recruited for the study. A novel methodology was devised to quantify the average brightness change of skin-applied UV ink before and after scrubbing via pixel intensity analysis. A black-box setup is constructed with an integrated high-resolution camera to photograph the UV-stained dorsal arm. Each stain was then digitally isolated for brightness comparison.
Results
It was observed that the 10SS technique was overall more successful in removing the UV ink in comparison to the 4MS method (p = 0.014). In addition, a bias was observed in removing more percentage of the proximal stains when compared to middle and distal stains with the 4MS technique (p = 0.0027), while location-based brightness change averages were statistically equal with the 10SS technique (p = 0.423).
Conclusions and Clinical Relevance
10SS provided not only a more mechanically efficient scrubbing but also a more homogenous cleaning than 4MS. We recommend the use of the 10SS technique to achieve more effective pre-surgical hand hygiene.
期刊介绍:
Since its establishment in 2003, The Surgeon has established itself as one of the leading multidisciplinary surgical titles, both in print and online. The Surgeon is published for the worldwide surgical and dental communities. The goal of the Journal is to achieve wider national and international recognition, through a commitment to excellence in original research. In addition, both Colleges see the Journal as an important educational service, and consequently there is a particular focus on post-graduate development. Much of our educational role will continue to be achieved through publishing expanded review articles by leaders in their field.
Articles in related areas to surgery and dentistry, such as healthcare management and education, are also welcomed. We aim to educate, entertain, give insight into new surgical techniques and technology, and provide a forum for debate and discussion.
