The doctors: Over 100 years of collective experience
As a senior retired ophthalmologist I have witnessed most of these changes. In 1962 when I was a junior medical school student Medicare came into existence.
The reference article focuses on the electronic health care record, which is too narrow a focus on changes over the last 49 years.
Perhaps the most annoying aspects of change have been the growth and interference with doctor and patient choices for treatments requiring authorizations for payment of claims. This interference is perhaps the one greatest change in health care. This is the result of increasing costs, yet health care costs continue to increase.
Recently increasing regulations and CMS rules have been found to increase costs offsetting any possible reductions in health care cost.
In an effort to decrease overhead, many physicians have created group medical practice business structure, in an effort to build an organization with greater negotiating power, and to reduce overhead. The former may be valid, the latter is in doubt.
