Unsafe Healthcare Practices: Who Will Speak Up?

I was reading the news about a situation that is alleged that a doctor was practicing in ways that was detrimential and harmful to patients. When I read further, it appears that the doctor is not alone as he worked in a clinic with other healthcare workers. This lead me to wonder, what happens when healthcare professionals and other office staff persons see practices that are questionable or wrong. Why aren't we speaking up and exposing the situations at hand before someone gets hurt, or worst dies. I have found in similar cases such as this, many times the reasons given were that in a sense people believed that they are helping the doctor and/or the patients. It is not uncommon, however, when things are in the open and the wrongdoing is evident, and that those who witnessed such acts become just as guilty that they are able to really understand why it was wrong.  I think as healthcare professions, we have to be willing to be uncomfortable when situations are compromising to the health and well-being of our patients or when they are just not the standards of care. I believe that the the cost spent in litigation is huge for the healthcare industry on cases such as this when the easier and more inexpensive remedy should have been to speak up against a harmful or unsafe practices of healthcare professionals. Wrong is wrong...right?...Who will speak up? Have you ever witnessed an unsafe healthcare practice?
