Confidentiality in health care. A survey of knowledge, perceptions, and attitudes among high school students.

OBJECTIVE: To assess adolescent knowledge, perceptions, and attitudes about health care confidentiality. DESIGN: Anonymous self-report survey with 64 items addressing confidentiality issues in health care. SETTING: Rural, suburban, and urban high schools in central Massachusetts. PARTICIPANTS: Students in ninth through 12th grades from three schools. RESULTS: A total of 1295 students (87%) completed the survey: 58% had health concerns that they wished to keep private from their parents, and 69% from friends and classmates; 25% reported that they would forgo health care in some situations if their parents might find out. There were differences in response by gender, race, and school. About one third were aware of a right to confidentiality for specific health issues. Of those with a regular source of care, 86% would go to their regular physician for a physical illness, while only 57% would go there for questions about pregnancy, the acquired immunodeficiency syndrome, or substance abuse that they wished to keep private. Sixty-eight percent had concerns about the privacy of a school health center. CONCLUSIONS: A majority of adolescents have concerns they wish to keep confidential and a striking percentage report they would not seek health services because of these concerns. Interventions to address confidentiality issues are thus crucial to effective adolescent health care.

Ocular manifestations and impression cytology of anorexia nervosa.

A prospective age- and sex-controlled study of seven anorexia nervosa patients and seven normal control patients was conducted to determine the ocular manifestations of anorexia nervosa. Slit-lamp examination of the anorexic patients demonstrated a high incidence (4/7) of multiple episcleral capillary aneurysms and subconjunctival hemorrhages. Two of seven anorexia nervosa patients had bilateral superficial punctate keratopathy. Anesthetized Schirmer tear testing demonstrated a significantly (P less than 0.005) reduced mean tear production in the anorexia nervosa group (11.3 mm) compared with the control group (22.4 mm). Masked interpretation of conjunctival impression cytology demonstrated moderate to severe conjunctival squamous metaplasia in the majority of the anorexia nervosa group (5/7) compared to normal conjunctival epithelium in the majority of the control group (5/7). Absence of nyctalopia, Bitot's spots, and xerosis, and lack of conjunctival goblet cell loss indicate that the anorexia nervosa group did not have vitamin A deficiency.
