Mclean Hospital is an American psychiatric hospital in Belmont, Massachusetts. McLean is a teaching hospital of Harvard Medical School and a member of Partners HealthCare. Founded in 1811 as the first psychiatric hospital in the United States, it was named after its founder, John McLean. The current campus comprises two buildings on 53 acres (21 ha) of land: the original building from 1811 and the newer Breckinridge Building from 1971. It also operates residential treatment facilities in Waltham and Canton, Massachusetts; North Reading, Massachusetts; and South Hamilton, Massachusetts. The average daily census is approximately 300 patients.
Inpatient care at McLean uses a multidisciplinary team approach with input from psychiatrists, psychologists, social workers, nurses, creative arts therapists, and addiction counselors. Treatment modalities include individual psychotherapy, group therapy, psychoeducation classes (such as stress management or assertiveness training), medication management by psychiatric nurses and physicians, experiential therapies (such as art therapy or equine-assisted therapy), as well as recreation therapy. Family involvement is encouraged through weekly visits and education about illness and treatment. Patients are also encouraged to attend 12-step meetings such as Alcoholics Anonymous or Narcotics Anonymous during their stay.
