The language of rights has long permeated discussions about health care in Britain, but during the latter half of the 20th century, patients' rights achieved a level of unprecedented prominence. By the end of the 1980s, the language of entitlement appeared to have spread into many areas of the National Health Service: consent to treatment, access to information, and the ability to complain were all legally established patients' rights. Patient organizations played a critical role in both realizing these rights and in popularizing the discourse of rights in health care in Britain. "Rights talk," however, was not without its drawbacks, as it was unclear what kinds of rights were being exercised and whether these were held by patients, consumers, or citizens.
