I think these restrictions are essentials and would help physicians and employers to avoid many problems at work. I think without any gifts restrictions, some people would go crazy thinking that the more expensive the gift we give is the more we will get back from the physician, and that would cause a lot of embarrassment and issues for people who have less income and more responsibilities and could be an extra thing to think about. AMA ethics and The Physician Payments Sunshine Act (PPSA) rules of 2010 put a clear end line for all participants in the US federal health care programs regarding gifts related concerns such as cash or other gifts made to physicians or education hospitals during either an internship or residency program.
From my research, I knew that each state has a different rule regarding gift restrictions. However, in New Jersey, “Starting January 15, 2018, all contracts and payments entered into by physicians directly with the pharmaceutical industry will be subject to a $10,000 total yearly cap for New Jersey physicians with all pharmaceutical companies. This includes payments from industry for consulting and speaking but exempts research and education related payments. In addition, physicians will be subject to a $15 dollar meal cap, for meals related to all activities.”
