Both components are connected via cable to the patient and to a central non-portable unit equipped with a speaker and a printer. Standard electronic fetal heart monitors have two main components-a Doppler ultrasound transducer used to detect the fetal heart rate and a tocodynamometer used to assess for uterine contractions. Electronic fetal heart rate monitoring, first proposed in 1958, has become an integral part of inpatient labor care, with approximately 85% of all hospital births using this technology by 2002. This does not alter their adherence to PLOS ONE Editorial policies and criteria.Įach year in the United States (US) approximately 4 million women give birth in hospitals, making childbirth the most common indication for admission to US hospitals.

Further research is needed to assess feasibility of using this technology in busy inpatient settings.Ĭitation: Boatin AA, Wylie B, Goldfarb I, Azevedo R, Pittel E, Ng C, et al. We found it to be acceptable to both pregnant women and clinicians. In this pilot study we found that this wireless fetal monitoring prototype technology has potential for use in a United States inpatient setting but would benefit from some technology changes. Both pregnant women and clinicians found the prototype technology likable (81.3% and 66.7% respectively), useful (96.9% and 66.7% respectively), and would either use it again or recommend its use to another pregnant woman (77.4% and 66.7% respectively). Recorded cardiotocographs received a mean score of 4.2/5 (± 1.0) on ease of readability with an interclass correlation of 0.81(95%CI 0.45, 0.96). Delays were ascribed to Wi-Fi connectivity problems. The primary technical problem observed was a delay in data transmission between the prototype and the web portal, which ranged from 2 to 209 minutes. Six non-study clinicians interacted with the prototype technology. Four sessions though completed, were not successfully uploaded to the Cloud storage. Thirty-two women were enrolled, 28 of whom (87.5%) successfully completed 30 minutes of fetal monitoring including transmission of cardiotocographs to the web portal. We assessed acceptability by administering closed and open-ended questions on perceived utility and likeability to pregnant women and clinicians interacting with the prototype technology. Three obstetricians also rated fetal cardiotocographs on ease of readability. We assessed functionality by evaluating the ability to successfully monitor the fetal heartbeat for 30 minutes, transmit this data to Cloud storage and view the data on a web portal. Women with full-term singleton pregnancies and no evidence of active labor were asked to wear the prototype technology for 30 minutes. We tested functionality and acceptability of a wireless fetal monitoring prototype technology in pregnant women in an inpatient labor unit in the United States.
