PROMS - Overview & Differences between surgeries Patient Reported Outcome Measures are validated, standardised sets of questions which when used routinely improve patients’ quality of life and survival (1). They can be use prospectively to direct individual care and help manage symptoms or retrospectively to assess the patient’s perspective on the differences between two alternate treatments. This talk will cover an overview of PROMs for breast cancer surgery broadly including their origins and evidence as well as discuss BRENDA, the St. Vincent’s Melbourne database which uses incorporated PROMs for cancer patients to direct care and inform patients about real life outcomes in our unit. 1.Balitsky AK, Rayner D, Britto J, Lionel AC, Ginsberg L, Cho W, . . .
