A tele-medicine home support programme for families of infants with major CHD is feasible, sustainable and effective. Home support with video-conferencing is superior to telephone consultations. Parents are highly satisfied with tele-homecare. Tele-homecare significantly reduces health service utilisation and may reduce health service costs.
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.
Videoconferencing is acceptable to parents and physicians and provides a more effective form of follow-up in terms of clinical observation and parental anxiety levels.
To compare the sensitivity, specificity, and predictive values of compression ultrasonography (US) in postoperative orthopedic patients with those of (a) impedance plethysmography in postoperative patients and (b) compression US in symptomatic outpatients, the authors performed an investigator-blinded cohort study. One hundred thirty-four consecutive inpatients who had undergone elective knee-replacement surgery or surgery for a fractured hip and 65 consecutive outpatients with clinically suspected venous thrombosis who had undergone venography were evaluated. Compression US allowed detection of 11 of 21 (52.4%) proximal-vein thrombi but was insensitive to calf-vein thrombi in the orthopedic patients. Compression US had a significantly greater specificity and positive predictive value than impedance plethysmography for all thrombi in orthopedic patients; compression US also had greater sensitivity. The sensitivity of compression US for proximal-vein thrombi was significantly higher (92.1%) in symptomatic outpatients than in orthopedic patients. The authors conclude that compression US has significant advantages over impedance plethysmography in the detection of proximal-vein thrombi in patients who have undergone hip- or knee-replacement surgery.
Over an eight-year period, echocardiograms were transmitted by ISDN at 384 kbit/s for a total of 132 patients suspected of having congenital heart disease (CHD). Five transmitted scans were inadequate. Hands-on echocardiograms were performed subsequently on 116 of the remaining 127 cases (91%). Major CHD was diagnosed in 42 of the 116 infants (36%) and minor CHD in 49 (42%). The telemedicine diagnosis was accurate in 97% of the cases (kappa = 0.90). There were four diagnostic errors. Transfer to the regional unit was avoided in 95 patients (72%). The present study shows that high diagnostic accuracy is possible using a telemedicine link to transmit images obtained with the assistance of real-time guidance by a paediatric cardiologist. The results also demonstrate the importance of an expert interpreting the echocardiographic images, since the accuracy of diagnosis was considerably improved (the kappa coefficient increased from 0.14 to 0.90).
Parents of children hospitalized with major congenital heart disease often state that the weeks following discharge from hospital are particularly difficult. There is a sudden change from 24-h medical supervision and care to outpatient reviews. Videoconferencing not only gives the family an opportunity to have visual and audio contact with staff but also allows clinicians to visually assess the patient. We have investigated the feasibility of using videoconferencing to provide support for families at home. We also report the early results of a randomized control trial comparing videoconference support with regular telephone support and the current clinic review follow-up.
In children over 7 years, it is possible to demonstrate the LV FFR by interval measurement of IVA during exercise. The availability of pediatric normal values for both this relation and resting LV IVA might facilitate future investigation of LV contractility and myocardial contractile reserve during childhood.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
