cardiopediatric home monitoring tool

Conditions: Congenital Heart Defect

Summary: we hypothesize that a home monitoring program combined with routine postoperative care significantly reduces morbidity and mortality after neonatal and pediatric cardiac surgery. this project differs from the previously published experiences by (a) providing an innovative telemedicine solution via the use of validated measurement sensors, (b) an alert system based on individualized standards, established for each care pathway, and (c) a protocolized response from medical teams in the management of alerts generated by the home monitoring tool.

affecting 12-million people worldwide and 7,400 newborns/year in france, congenital heart defects (chd) are the leading cause of birth defects and a major cause of morbidity and mortality in childhood. it is (a) a growing patient population, due to an increase in birth prevalence and survival, and (b) a major public health issue, due to a substantial use of healthcare resources and a dramatic impact on quality of life. chds concerned by the oscar project are rare diseases (prevalence \<1/2000 births) operated on at birth or in infancy. these chds expose affected newborns/infants to the risk of major cardiovascular events (fainting, cyanosis, arrhythmias) and/or rapid cardiac decompensation occurring at home in the postoperative period, justifying close ambulatory monitoring to detect early warning signs of complication or decompensation (such as oxygen desaturation, accelerated heart rate, poor weight gain, altered tone, etc.) this risk is particularly high in certain critical postoperative situations, such as when the physiology of a single ventricle is palliated by a shunt (modified blalock-taussig systemic-pulmonary anatomy), or in the intermediate period (interstage) between two palliative surgeries in a norwood program. in view of the high ambulatory mortality (12-20% in current series) during the interstage of a norwood program, some expert centers around the world have opted not to discharge operated neonates home, preferring to keep in-hospital monitoring during 4 to 5 months, until stage 2, thus reducing mortality during this critical period. in anglo-saxon countries, an outpatient monitoring program has been developed as an alternative for these vulnerable patients, sometimes accompanied by a telemedicine solution, greatly reducing postoperative mortality. this type of outpatient follow-up program does not exist in france.
