Health Care Pulse - or something similar. If you have hired a health care service (home health care, senior care, etc.) or work for a private health care service, these people are contracted by that health care service to contact you and get your opinion(s) about them. That's the good part. The bad part is that they tend to call you like a collection agency: they keep calling and calling and calling until you finally answer the phone. Other than that, they're harmless; take the call.
