Referral guidelines are meant to help providers decide if a specialty referral is needed. They are not intended to be comprehensive management algorithms. The clinical guidelines and policies on this page assist clinicians in standardizing the evaluation, diagnosis, and care of patients, with the goal of achieving optimal outcomes. The guidelines translate national recommendations and the best available evidence into local context. Adherence to these guidelines should limit unwanted or unintended variation in practice, but guidelines are not meant to be prescriptive. The clinician retains the responsibility to select the appropriate guideline for a particular patient and to use the guideline to the extent that it serves the individual patient.
