Rio Grande do Sul state's referral list for endocrinology evaluation in specialized care is highly overloaded. There is currently a referral protocol to select patients how should be referred. It will be evaluated if a intervention of telephone-based teleconsultations provided by the TelessaúdeRS to the primary care physicians can provide additional benefits. TelessaúdeRS is a telehealth program from the University of Rio Grande do Sul. This will be evaluated in a cluster randomized clinical trial.
