Can you elaborate on the PPE? Double gloving has been the subject of a Cochrane Review http://onlinelibrary.wiley.com/doi/10.1002/14651858.CD003087.pub2/pdf
Double gloving carries less of a risk to surgeons of acquiring blood borne pathogens when operating on patients who pose an infection transmission risk-eg patients with Hepatitis C.

Precautions for the surgeon by wearables has been reviewed extensively. If you want safety for your patients you might want to take a look into the surgical checklists like SURPASS (E. de Vries, NEJM).
