This week health care professionals are gathering in Sioux Falls at the Violent Crime and Human Trafficking Conference sponsored by Avera Health and the Department of Justice. Avera has new protocols for health care professionals if they suspect patients are victims of sex trafficking. Nurses, doctors and other health care workers can listen for red flags during assessments and move to more standard questions to identify abuse. Avera Health chief medical officer Tad Jacobs says with heightened awareness, health care professionals can look for clues. He says sometimes those clues are very subtle and not very obvious. Dr. Jacobs joined Dakota Midday and discussed new efforts among health care systems to identify and help victims of human trafficking.
