The aim of this study was to examine to what extent patients remained silent to the health care system after they experienced abusive or wrongful incidents in health care. Female patients visiting a women’s clinic in Sweden (n = 530) answered the Transgressions of Ethical Principles in Health Care Questionnaire (TEP), which was constructed to measure patients’ abusive experiences in the form of staff’s transgressions of ethical principles in health care. Of all the patients, 63.6% had, at some point, experienced staff’s transgressions of ethical principles, and many perceived these events as abusive and wrongful. Of these patients, 70.3% had remained silent to the health care system about at least one transgression. This silence is a loss of essential feedback for the health care system and should not automatically be interpreted as though patients are satisfied. / <p>funding agencies|Nordic Council of Ministers||Swedish Research Council|2009-2380|</p>
