A therapist working in an outpatient surgery center receives a phone call from a woman demanding to know when her (adult) son's appointment is. The therapist obviously cannot disclose this information, and the mother becomes very angry and abusive with the therapist and threatens to make a complaint. After the phone call, the therapist, who has access to all practice patients' electronic surgery records, goes to make a note about the conversation on the system. However, the therapist accesses the woman's notes accidentally and not her son's. The therapist realizes the mistake, but not before spotting that the woman has a diagnosis of a serious mental health disorder, which might explain the woman's behavior. The therapist mentions to his supervisor the possibility of a complaint being brought by the woman, and also mentions that the woman has a history of mental health problems. Do you feel that there has been a breach of confidentiality? Why, or why not? How do you feel the supervisor should handle this situation?
