@y0ssarian87 - Thanks for sharing this story. As tragic as it is, it greatly illustrates the dangers of not being mindful of sexual behavior diversity and of risk factors that may be more relevant to specific LGBTQ patient populations.
I remember once as a pharmacy student I had a very frustrating conversation with a faculty member about the importance of LGBT cultural competency. The faculty member said something along the lines of, "well, you would treat their hypertension the same way you would treat anyone's hypertension, so what does it matter?" and completely missing the point and proving it at the same time. It's not about treating people differently - people ultimately have the same needs - it's about knowing how to best approach their needs and account for differences in behavior and environment that can have an outcome on treatment. Even with hypertension, which is supposedly straightforward enough, I suppose I could ask all my patients if they use poppers, which might interact with their antihypertensives, but it might be more important to check in with my gay male patients about their popper usage. Not to mention, if I didn't have any LGBT cultural competency, I probably wouldn't even know what poppers were to begin with.
