Over the last three decades, the major health risks facing U.S. adolescents have shifted drastically: Teen pregnancy and alcohol, cigarette and drug use have fallen while anxiety, depression, suicide and self-harm have soared. In 2019, the American Academy of Pediatrics issued a report noting that “mental health disorders have surpassed physical conditions” as the most common issues causing “impairment and limitation” among adolescents. In December, the U.S. Surgeon General, in a rare public advisory, warned of a “devastating” mental health crisis among American teens.

But the medical system has failed to keep up, and the transformation has increasingly put emergency rooms and pediatricians at the forefront of mental health care. Community doctors now routinely deal with complex psychiatric issues, making tough diagnoses after brief visits and prescribing powerful psychiatric medications for lack of better alternatives. “Pediatricians need to take on a larger role in addressing mental health problems,” the 2019 A.A.P. report concluded. “Yet, the majority of pediatricians do not feel prepared to do so.”

Dr. Cori M. Green, a co-author of that report and a pediatrician at Weill Cornell Medicine, said medical training lagged behind. “We need to overhaul the whole system,” she said. “We need to see mental health through a prevention lens and stop seeing physical health as different than mental health.”
