An increasing number of U.S. hospitals have adopted policies that explicitly ban discrimination against lesbian, gay and bisexual patients, according to a report to be released Tuesday. An annual survey by the Human Rights Campaign, an advocacy group, found that over 95 percent of more than 400 hospitals and clinics included sexual orientation in their nondiscrimination policies and nearly 80 percent included gender identity in those policies. Additionally, more than 65 percent of inpatient hospitals had explicit policies granting equal visitation rights to same-sex couples and same-sex parents.
