Researchers associated with South Miami Hospital (SMH) developed a new experimental laser treatment for heart patients. Its development team and the physicians who use the laser consider it to be a lifesaving advance. It should be noted that the physicians who are touting the laser hold a significant stake in the company that produces the laser. To offer a substitute for a balloon angioplasty to treat heart blockages, the experimental laser was developed at a cost of $250,000. SMH estimates that it will cost $20,000 to install the laser. The procedure requires a nurse at $50 per hour, a technician at $30 per hour, and a physician who is paid $750 per hour. Patients are billed $3,000 for the procedure compared to $1,500 for the traditional balloon treatment. Is it proper for physicians to recommend this procedure when they have a vested interest in its usage?
