The evolving subspecialization of psychiatry: implications for the profession.

Psychiatry is likely to evolve into a number of subspecialty areas, paralleling developments in other medical specialties. These changes are impelled both from within psychiatry, where the rapid increase in knowledge and skills makes mastery of the entire field by any one practitioner less possible, and from without, related to new expectations for psychiatric services from referral sources and patients, increasing competition by other physicians and nonphysician mental health care providers, and shifting reimbursement patterns. The authors discuss the advantages and disadvantages of subspecialization as well as implications for psychiatric practitioners and training programs.
