The relationship between having a regular general practitioner (GP) and the experience of healthcare barriers: a cross-sectional study among young people in NSW, Australia, with oversampling from marginalised groups.

General practice is the appropriate setting for preventive health care and care coordination. Having a regular GP is associated with fewer barriers and more positive attitudes to health system navigation and may provide better engagement with and coordination of care. Strategies are needed to increase the proportion of young people who have a regular GP.
