Openness about one's sexual orientation in the health care context contribu
tes to lesbians satisfaction with care and to continued use of health servi
ces. We undertook a qualitative study to examine lesbians experiences in th
e health care environment and explain why openness about sexual orientation
may be resisted by lesbians. Data were derived from four focus groups cond
ucted with lesbians who discussed their expectations and preferences for th
eir health care, as well as their met and unmet health care needs. Transcri
pts of the focus groups were analyzed using NUD*IST qualitative software to
derive salient themes presented by the women. Five major themes were ident
ified: anxiety and concern related to self-disclosure, non-disclosure of se
xual orientation, seeking out gay-positive physicians, frustration with ass
umptions of heterosexuality, and treatment of lesbian partners. Examples fo
r each of the major themes are provided. Data from this study suggest ways
health care providers can alleviate concerns among lesbian patients. Our fi
ndings also suggest the need for formal training on lesbian health and meth
ods for making medical professionals more comfortable with diverse sexual o
rientations.
