"Medical transcription experts listen to dictated recordings made by physicians and other health care professionals and transcribe them into medical reports, correspondence, and other administrative material. They generally listen to recordings on a headset, using a foot pedal to pause the recording when necessary, and key the text into a personal computer or word processor, editing as necessary for grammar and clarity.

The documents they produce include discharge summaries, history and physical examination reports, operative reports, consultation reports, autopsy reports, diagnostic imaging studies, progress notes, and referral letters. Medical transcriptionists return transcribed documents to the physicians or other health care professionals who dictated them for review and signature, or correction. These documents eventually become part of patients’ permanent files.

The majority of these workers are employed in comfortable settings, such as hospitals, physicians’ offices, transcription service offices, clinics, laboratories, medical libraries, government medical facilities, or their own homes. Many medical transcriptionists telecommute from home-based offices as employees or subcontractors for hospitals and transcription services or as self-employed, independent contractors."
