Our healthsystem uses VCS-Vendor Credentialling Service (www.vcsdatabase.com) for outside vendors that service healthcare equipment or other facility-based machinery or services. The vendor has to create a profile with VCS who does background checks, medical & security screenings, etc. We have two kiosks that reps have to swipe an ID when they arrive to get a printed, dated (sticky) name badge to wear while on-site. The badge denotes different levels of access.
We are no longer able to have vendor sales in our lobby, so I have not asked those vendors to participate in VCS, but suspect I would be expected to do so if we had continued to have sales.
