The document introduces the Know Your Numbers program, which aims to improve healthcare staff's alcohol-specific health literacy. It does this through a behavioral change approach that teaches staff to calculate a patient's risk level based on their weekly alcohol units, rather than categorizing them. The program conducted trainings and assessments that demonstrated increased ability to correctly estimate units of alcohol and confidence in discussing alcohol with patients. It produced online trainings, apps, and materials to continue disseminating the Know Your Numbers approach.
