Maternal self-administered fetal heart rate monitoring and transmission from home in high-risk pregnancies

Abstract 

Objectives: To evaluate the feasibility of high-risk pregnancy surveillance by patient-directed fetal heart rate monitoring and transmission, and to assess patient satisfaction with this technology. Methods: Thirty-six women with high-risk pregnancies performed daily non-stress tests at home and transmitted the data to our perinatal care center by telephone. At each transmission, patients were asked by a physician about perceived fetal movements and uterine contractions and given the results. If the tracing was unsatisfactory, further evaluation was performed. In addition, patients completed a questionnaire on quality of life and anxiety state before and after the study. Results: All patients were able to perform the tests and transmissions. The quality of recorded data was significantly correlated with maternal body mass index, but not with gestational age at the time of monitoring or birth weight. Thirty-nine of the total 562 tracings (6.9%) were inconclusive or non-reassuring. After repeated testing, 32 of them (82%) were considered normal, and seven patients (18%) were referred for additional in-hospital evaluation. Of this group, four were discharged for further surveillance with routine home monitoring and the remaining three were hospitalized for continued evaluation. There were no significant immediate adverse maternal or neonatal outcomes as a result of the monitoring. Patient satisfaction was high. Conclusions: Daily home FHR monitoring in high-risk patients is safe and feasible at all gestational ages, based on this initial pilot evaluation. It is easily and reliably performed and accepted by patients with a high level of satisfaction.
