Abstract

OBJECTIVES: To determine the accuracy of remote diagnosis of congenital heart disease (CHD) by real-time transmission of echocardiographic images via integrated services digital network (ISDN) lines, to assess the impact on patient management and examine cost implications.

DESIGN: Prospective comparison of echocardiograms on infants with suspected significant CHD performed as follows: (1) hands-on evaluation and echocardiogram by a paediatrician at a district general hospital (DGH) followed by (2) transmission of the echocardiogram via ISDN 6 with guidance from a paediatric cardiologist and finally (3) hands-on evaluation and echocardiogram by a paediatric cardiologist. The economic analysis compares the cost of patient care associated with the telemedicine service with a hypothetical control group.

SETTING: Neonatal units of three DGH and a UK regional paediatric cardiology unit.

RESULTS: Echocardiograms were transmitted on 124 infants. In five cases scans were inadequate for diagnosis. Of the remaining 119 tele-echocardiograms, a follow-up echocardiogram was performed on 109/119 (92%). Major CHD was diagnosed in 39/109 infants (36%) and minor CHD in 45 (41%). The tele-echo diagnosis was accurate in 96% of cases (kappa=0.89). Unnecessary transfer to the regional unit was avoided in 93/124 patients (75%). Despite relatively high implementation costs, telemedicine care was substantially cheaper than standard care. Each DGH potentially saved money by utilising the telemedicine service (mean saving: pound728/patient).

CONCLUSIONS: CHD is accurately diagnosed by realtime transmission of echocardiograms performed by paediatricians under live guidance and interpretation by a paediatric cardiologist. Remote diagnosis and exclusion of CHD affects patient management and may be cost saving.
