Home Blood Pressure Measurement and Self-Interpretation of Blood Pressure Readings During Pregnancy: Hy-Result e-Health Prospective Study.

Introduction: Hy-Result is a rule management system designed to help patients to be compliant with the home blood pressure measurement (HBPM) monitoring schedule and to understand their BP readings. The aim of the Hy-Result e-Health prospective study is to evaluate the practice and experience of women using the Hy-Result coaching app for self-interpretation of BP readings during and after pregnancy. Methods: Participants were asked to: i) measure their BP at home; ii) use the Hy-Result app and send their PDF report to the researcher; iii) answer anonymously to 3 online independent questionnaires (Q). Results: A total of 107 women accepted to measure their BP and use the app. Among them 82 (77%) performed HBPM and used successfully the system and 72 (88%) shared to the investigator their PDF report by email. Of these, 95% declared the software was "easy" or "very easy" to use; 93% believe the software helps them to monitor their BP more effectively (74% agree, 18% somewhat agree); 94% that the color code classification was "clear"; 76 (93%) affirmed that the app helped them when consulting their physician for their BP evaluation. Majority (87%) perceived the software to be reliable. Furthermore, 71 (87%) said they trust the system and 51 (62%) declared that performing HBPM and self-interpret their readings was "reassuring" whereas 6 (7%) felt that it was "a concern". Conclusion: This study shows that the majority (88%) of pregnant women performed HBPM and successfully used the Hy-Result software for self-interpretation of the BP readings. The use of the validated Hy-Result system by pregnant women may thus be recommended in common practice by healthcare professionals and patient associations.
