Abstract

BackgroundExcessive venipunctures are a significant problem both in emergency rooms and during hospital stays. Near-infrared NIR illumination devices improve venipuncture success rate but their usage is limited by their availability and economic cost. The objectives of this study were to develop a low-cost NIR spectroscopy prototype from a standard mobile device, to evaluate its efficacy and acceptance as an educational tool, and in a clinical setting.

MethodsThrough a user-centric design process a prototype device was developed. Its educational efficacy was evaluated through a non-invasive, observational study 20 student clinicians, 25 subjects and its acceptance was assessed using quantitative and qualitative analysis. A smaller clinical trial was performed by a group of 4 medical professionals over a period of 6 weeks that involved 64 patients.

ResultsThe prototype enables real-time visualization of peripheral veins on a variety of Android-based devices. The prototype was 35.2% more successful in visualizing and locating veins n = 500 attempts than the nursing students. The acceptance assessment revealed high perception of usefulness, satisfaction, and ease of use. In the clinical trial, 1.6 SD 1.3 additional veins per patient were identified compared with the traditional visualization methods.

ConclusionsTo the best of our knowledge this is the first study that describes the design, feasibility and application of an NIR spectroscopy prototype developed on a standard mobile device.
