Domiciliary Fetal Monitoring in a District Maternity Unit

Abstract

Domiciliary Fetal Monitoring is a new technique which allows fetal heart rate monitoring from within a patient's home. The 30 minute cardiotocograph is transmitted by telephone, to a central labour ward computer, within 45 seconds. Of 522 domiciliary cardiotocographs performed on 100 consecutive patients, 356 (68%) were performed for suspected intrauterine growth retardation or reduced fetal movements. Thirty one (5.9%) recordings were abnormal; a repeat cardiotocograph in hospital was abnormal in 9 cases (1.3%); all such patients were delivered within 7 days. The induction rate for the study group was increased by a factor of 3.2 with respect to all hospital confinements; 49% of infants were small for gestational age (less than 10th percentile). Caesarean section and forceps delivery rates were the same for both groups. No stillbirths occurred in the study group. After the introduction of domiciliary monitoring, the number and duration of hospital admissions for fetal surveillance were reduced by 29% and 52% respectively. Patients were equally as able as midwives to perform domiciliary fetal monitoring. A patient survey revealed widespread satisfaction with the DFM system.
