The role of the telephone in medical practice is important, but often probl
ematic. Mistakes in telephone diagnosis and triage can have severe conseque
nces. An effective office system can reduce liability risks, and in some ca
ses telephone contact can substitute for office visits. Internists feel unp
repared to provide telephone care. Therefore, residency education needs to
focus on documentation, consultant availability, and performance feedback.
Research should focus on improving outcomes, reimbursement issues, and tech
nologic advances. This article describes internists' telephone interactions
with ambulatory patients, preparation for telephone medicine, and aspects
of office telephone systems and makes comparisons with other primary care f
ields.
