Environmental Impact of a Novel UV-C Disinfection Machine for Non-Channel Flexible Laryngoscopes.
Article in Laryngoscope investigative otolaryngology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objectives: Infection prevention in hospitals is a highly discussed and regulated process for endoscopy in Otolaryngology. The current standard for endoscopes involves high level disinfection (HLD). The UV-SMART D60 disinfection machine utilizes Impelux UV-C light technology. This study aimed to evaluate the environmental impact of the D60 machine within an otolaryngology department in comparison to current HLD protocols. Methods: Three equipment, materials, and disposables audits were conducted where the turnover and HLD process of a single non-channeled laryngoscope was analyzed. Every item involved in the cleaning process was documented for both standard HLD and D60 workflows. Water quantity was documented and a power meter was used to determine the wattage of the machinery used. Additionally, scope turnover time was documented and CO Results: Results demonstrated a significant reduction in material usage with the D60 including reduced PPE. The total water usage was about 45 L more per scope for traditional HLD. Power analysis demonstrated a reduction of 250 watts per scope. Additionally, the D60 reduced CO Conclusions: Environmental analysis demonstrates a significant amount of usage of disposables, water, and energy per non-channeled nasolaryngoscope with current HLD protocols. UV-C HLD resulted in less consumption of these resources. The marked reduction in turnover time and scope handling represents a significant opportunity for clinical efficiency, cost reduction, and resource consumption and will merit further investigation when FDA approval is granted. Level of Evidence: N/A.
