A recent study, the results of which were published in the American Journal of Public Health, shows that health care providers show bias based upon sexual orientation. To summarize these findings, Medical Press reports that health care providers, "similar to others in society, hold a bias for people who shared their own sexual identity." These results stem from the Sexuality Implicit Association Test, which was developed to assess the presence of implicit bias toward those of varying sexual orientation. More than 200,000 people participated in this test between May 2006 and December 2012. Participants included medical doctors, nurses, mental health care providers, and other treatment providers.
Lead researcher Janice Sabin pointed out that clinical care of the LGBT population is a neglected area in curricula in of studying nurses, medical doctors, and other care providers, reports Medical Press. You can read more of that story here, and see the study itself here.
