Dear Bob, Concerned subscribers to this list together with other interested physicians might undertake a formal study to assess the quality of medical care rendered by private and public corporations. Such a study would entail a data bank, which unlike its federally mandated counterpart would focus not upon the derelictions that flow from the negligence of individual physicians but on the derelictions that flow from the negligence of the physicians' employers. One would have to be extraordinarily cautious not to lay oneself open to charges of libel. However such risks would arise not from the collection of the information but from the use that was made of it, a decision that should be postponed until after the information about any given institution had been obtained. The mere existence of such a project would probably have a salutary effect; for, as Francis Bacon said, knowledge itself is power. Ernst Meyer
