In a survey administered at HIMSS by anonymous health IT blogger HIStalk, more than four in 10 women said they experienced "unwanted sexual overtures or comments" at the conference that made them feel uncomfortable.
Additionally, 14 percent of male respondents indicated experiencing such unwanted advances.
Overall, 22 percent of survey respondents said they were made uncomfortable at HIMSS.
The anonymous blogger also shared some comments from respondents, including one female attendee who mentioned the "rampant misogyny" at the conference.
"The conference has a problem with making all of its attendees feel welcome and safe in a professional environment," wrote HIStalk.
Gender-based discrimination at tech conferences has been a longstanding issue, and this year the issue was brought to the forefront when a Craigslist ad seeking a "HIMSS '16 Conference Booth Girl" evoked criticism for its blatant sexism.
HIStalk outlined several suggestions to eliminate this type of sexist behavior, including publish a zero-tolerance code of conduct for HIMSS participants, prohibit sexually related images or suggestive attire as part of the exhibitor policy, allow anonymous reporting of unwanted attention and offer safe rides to attendees who seek them.
