Most psychiatric care in the United States happens in primary care, not in specialty psychiatry. The primary care physician treats most depression, most anxiety, most ADHD, most uncomplicated psychiatric illness. Specialty psychiatry's role is to support, consult, and take over for complexity — not to displace primary care psychiatric work.
The collaborative care model is the evidence-based structure for integrating psychiatric support into primary care. A care manager (often a clinical social worker or nurse) coordinates psychiatric care in the primary care setting, with a consulting psychiatrist available for case review and complex decisions. The PCP prescribes and manages most cases; complex cases get psychiatric consultation; the care manager bridges everyone. Trial data show better outcomes than usual care.
The integrated psychiatrist role in collaborative care is largely consultative — caseload review with the care manager, occasional direct visits for complex cases, education for primary care. Different from traditional outpatient psychiatry; the psychiatrist sees fewer patients individually but affects more patients through the system.
When primary care should manage: uncomplicated depression and anxiety, especially first episode. Most ADHD without comorbid substance use. Stable patients on long-term psychiatric medications without recent changes. Adjustment disorders. Mild OCD or other conditions where evidence-based primary care management works.
When specialty psychiatry should take over: Treatment-resistant illness. Complex comorbidity. High-risk regimens (clozapine, lithium with renal concerns, complex polypharmacy). Severe illness that exceeds typical primary care expertise. Specific specialty-required treatments (ECT, TMS, specialty psychotherapy).
Communicate back to the PCP when you do see patients on referral. Letter or message after evaluation. Specific recommendations. Plan for ongoing roles. Don't disappear with the patient; the PCP often has the longer relationship and the broader medical context.
The system depends on the collaboration. Specialty psychiatry can't see every patient with depression; primary care can't manage every complex case. Match patients to the right setting; communicate across the boundary.
