Patient-centered Treatment of Anxiety After Low-Risk Chest Pain in the Emergency Room

Those randomized to primary care and enhanced primary care coordination will receive the minimal intensity treatment that includes: (1) assistance in identifying a primary care provider for participants who do not have one, (2) sharing results of diagnostic testing (including anxiety screening) with the primary care provider (results sent via EMR note, mailed letter, or delivered by participant at appointment); and (3) an educational brochure on anxiety and treatment.

Individuals randomized to the online Cognitive Behavioral Therapy (CBT) + peer support guidance arm will receive access to six online, evidence-based CBT modules in the This Way Up Generalized Anxiety Course to be completed weekly or bi-monthly. Individuals who screen positive on the PHQ panic measure will complete 2 additional panic-specific homework assignments applying exposure therapy to panic (in addition to Generalized Anxiety Disorder) experiences aligned with content from the This Way Up Panic Course.

Individuals randomized to therapist-led CBT via telehealth will receive 8 one-hour sessions over the course of 8 to 10 weeks via telehealth (HIPAA compliant software such as Zoom Health or AmWell) or telephone. Therapists will be master's-degreed or eligible clinicians trained in CBT by our study psychologist. Therapists will follow a manualized protocol for delivering CBT for anxiety, specifically, with a primary focus on anxiety and worry management. Individuals who screen positive on the PHQ panic measure will have training in exposure therapy added to CBT. Although many CBT trials have a standard length of 12 sessions, brief CBT lasting 4-8 sessions is equally efficacious.
