title: Effect of an Internet-based system for doctor-patient communication on health care spending.
abstract: We studied the effect of a structured electronic communication service on health care spending, comparing doctor office and laboratory spending for a group of patients before and after the service became available to them relative to changes in a control group. In the treatment group, doctor office spending and laboratory spending fell in the period after the service became available, relative to the control group (p < 0.05). A rough estimate is that average doctor office spending per treatment group member per month fell $1.71 after availability of the service, and laboratory spending fell roughly $0.12. Spending associated with use of the electronic service was $0.29 per member per month. We conclude that use of structured electronic visits can reduce health care spending.
