Literature related to transgender health in adults has focused on definitions, hormone therapy, and transgender-sensitive care provision. Further understanding is needed on the delivery of primary care for transgender adults. The aim of this review was to understand the primary-care needs and access to health care services for transgender adults in Canada. A state-of-the-art literature review was conducted. Thirteen research studies were included. There is limited literature on the delivery of primary care for transgender adults, particularly in Canada. Health care issues and access to care have been explored. However, there remains minimal Canadian content on primary-care delivery for transgender adults. Additional studies are needed to understand transgender primary-care needs in Canada. Further understanding can reduce the invisibility and disparities experienced by transgender individuals. With better understanding of transgender primary health care issues, primary-care practitioners can advocate for the heath needs of their patients and improve care delivery.
