Ultrasonography, Prenatal
Conditions
Brief summary
Mobile medical devices for self-patient-use, are a rapidly evolving component of telehealth. Study examines the feasibility of using the INSTINCT® device, a portable self-use ultrasound system attached to a commercial smartphone in remote pregnancy assessment. Study aims to evaluate its safety, efficacy and usability.
Detailed description
Study includes women carrying a singleton fetus at 14 to 40 gestational weeks. Women with multiple gestations, non-viable fetus at recruitment and those with a major fetal anatomical malformation or genetic syndrome are excluded. Each participant receives the device for a self-use period of 7-14 days, instructed to preform 1-3 scans a day. Each participant completes a self-assessment questionnaire which aims to evaluate satisfactory and usability (user experience and satisfaction). Each scan will be evaluated for the possibility to properly view fetal heart activity, amniotic fluid volume, fetal tone, fetal body and breathing movements.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Safety - Device related SAE's | Through study completion until all subject gave birth, an average of 1 year | The device will be deemed safe if all SAE will be classified as not device related |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| User experience level | Through study completion, an average of 1 year | User experience will be defined positive if the mean value of all answers to user satisfaction related questions in the CRF is better or equal 3.5 out of 5. Questions will be graded by a visual analog scale with scores of 1 to 5 (1=very poor, 5=very high) |
| Usability rating | Through study completion, an average of 1 year | Usability will be defined positive if the mean value of all answers to usability related questions in the CRF is better or equal 3.5 out of 5. Questions will be graded by a visual analog scale with scores of 1 to 5 (1=very poor, 5=very high) |
| Device Sensitivity level | Through study completion, an average of 1 year | Medical data recorded by the device will be defined useful if: At least 70% of 3 out of 5 tested parameters (Fetal Heartbeat, Movements, Tone, Breathing and Amniotic fluids) were classified by professional evaluator as could be estimated. In more than 90% of scans, professional evaluator will be able to define Fetal Viability (identification of at least one of the following parameters: Fetal Heartbeat, Movements, Tone and Breathing) |
