Objectives: This study aimed to (1) estimate patients' willingness to pay (WTP) for remote monitoring (RM) and patient self-measurement (PSM) for pregnant women at risk of gestational hypertensive disorders, (2) assess the impact of experience with these technologies on WTP, and (3) determine their impact on health-related quality of life (HRQoL)., Methods: Data collection was part of a multicentric randomized controlled trial, Pregnancy Remote Monitoring II, with 2 interventions: RM and PSM. A contingent valuation survey, combining a payment card and open-ended question, was completed twice by 199 participants. Two-part models analyze the impact of experience on WTP, regression models estimated using ordinary least squares the impact of RM and PSM on HRQoL., Results: The mean WTP amount was approximately €120 for RM and €80 for PSM. Compared with having no experience, WTP RM was €63 higher after a long-term exposure to RM (P = .01) and WTP PSM was €26 lower after a short-term exposure to RM (P = .07). No significant impact of RM or PSM on HRQoL was found., Conclusions: This study contributes to the discussion on the impact of experience on WTP. Those who had a long-term experience with RM, were willing to pay more for RM than those without experience. This confirms our hypothesis that involving patients without experience with the valued treatment, possibly underestimates WTP. A long-term experience has, however, no impact on the WTP for technologies for which the potential benefits are apparent without experiencing them, such as PSM., Competing Interests: Author Disclosures Author disclosure forms can be accessed below in the Supplemental Material section., (Copyright © 2024.

Background/Objectives : Gestational hypertensive disorders (GHD) pose significant maternal and fetal health risks during pregnancy. Preconception physical exercise has been associated with a lower incidence of GHD, but insights into the cardiovascular mechanisms remain limited. This study aimed to evaluate the effect of preconception physical exercise on the complete cardiovascular functions of women at risk for GHD in a subsequent pregnancy. Methods : A non-invasive hemodynamics assessment of arteries, veins, and the heart was performed on 40 non-pregnant women at risk for developing GHD in a subsequent pregnancy. Measurements of an electrocardiogram Doppler ultrasound, impedance cardiography and bio-impedance spectrum analysis were taken before and after they engaged in physical exercise (30-50 min, 3×/week, 4-6 months). Results : After a mean physical exercise period of 29.80 weeks, the total peripheral resistance (TPR), diastolic blood pressure and mean arterial pressure decreased in the total study population, without changing cardiac output (CO). However, in 42% (9/21) of women categorized with high or low baseline CO (>P75 or

In contrast to whole body bioimpedance, which estimates fluid status at a single point in time, thoracic bioimpedance applied by a wearable device could enable continuous measurements. However, clinical experience with thoracic bioimpedance in patients on dialysis is limited. To test the reproducibility of whole body and thoracic bioimpedance measurements and to compare their relationship with hemodynamic changes during hemodialysis, these parameters were measured pre- and end-dialysis in 54 patients during two sessions. The resistance from both bioimpedance techniques was moderately reproducible between two dialysis sessions (intraclass correlations of pre- to end-dialysis whole body and thoracic resistance between session 1 and 2 were 0.711 [0.58-0.8] and 0.723 [0.6-0.81], respectively). There was a very high to high correlation between changes in ultrafiltration volume and changes in whole body thoracic resistance. Changes in systolic blood pressure negatively correlated to both bioimpedance techniques. Although the relationship between changes in ultrafiltration volume and changes in resistance was stronger for whole body bioimpedance, the relationship with changes in blood pressure was at least comparable for thoracic measurements. These results suggest that thoracic bioimpedance, measured by a wearable device, may serve as an interesting alternative to whole body measurements for continuous hemodynamic monitoring during hemodialysis. NEW & NOTEWORTHY We examined the role of whole body and thoracic bioimpedance in hemodynamic changes during hemodialysis. Whole body and thoracic bioimpedance signals were strongly related to ultrafiltration volume and moderately, negatively, to changes in blood pressure. This work supports the further development of a wearable device measuring thoracic bioimpedance longitudinally in patients on hemodialysis. As such, it may serve as an innovative tool for continuous hemodynamic monitoring during hemodialysis in hospital or in a home-based setting.

Background: The peripartum period, defined as the period from the beginning of the gestation until 1 year after the delivery, has long been shown to be potentially associated with increased levels of stress and anxiety with regard to one's transition to the status of parent and the accompanying parental tasks. Yet, no research to date has investigated changes in intrapersonal factors during the peripartum period in women at risk for pregnancy-induced hypertension (PIH)., Objective: The aim of this study is to explore and describe changes in intrapersonal factors in participants at risk for PIH., Methods: We used an explorative design in which 3 questionnaires were sent by email to 110 participants the day following enrollment in the Pregnancy Remote Monitoring program for pregnant women at risk for PIH. Women were invited to complete the questionnaires at the beginning of their participation in the Pregnancy Remote Monitoring project (mostly at 14 weeks of gestation) and after approaching 32 weeks of gestational age (GA). The Generalized Anxiety Disorder-7 Scale (GAD-7) and the Patient Health Questionnaire-9 were used to assess anxiety and depression, and adaptation of the Pain Catastrophizing Scale was used to measure trait pain catastrophizing., Results: Scores were significantly higher at 32 weeks of GA than at the moment of enrollment (GAD-7 score=7, range 4-11 vs 5, range 3-8; P=.01; and Patient Health Questionnaire-9 score=6, range 4-10 vs 4, range 2-7; P<.001). The subscale scores of the Pain Catastrophizing Scale were all lower at 32 weeks of GA compared with 14 weeks of GA (rumination: 4, range 1-6 vs 5, range 2-9.5; P=.11; magnification: 3, range 1-5.5 vs 4, range 3-7; P=.04; and helplessness: 5, range 2-9 vs 6, range 3.5-12; P=.06). The proportion of women with a risk for depression (GAD-7 score >10) was 13.3% (10/75) at enrollment and had increased to 35.6% (26/75) at 32 weeks of GA., Conclusions: This study shows that pregnant women at risk for PIH have higher levels of stress and anxiety at 32 weeks of GA than at the moment of enrollment. Further research is recommended to investigate potential strategies to help pregnant women at risk for PIH manage feelings of stress and anxiety., Trial Registration: ClinicalTrials.gov NCT03246737; https://clinicaltrials.gov/study/NCT03246737., (©Dorien Lanssens, Thijs Vandenberk, Valerie Storms, Inge Thijs, Lars Grieten, Lotte Bamelis, Wilfried Gyselaers, Eileen Tang, Patrick Luyten.

Background: There has been an exponential growth in the availability of apps, resulting in increased use of pregnancy apps. However, information on resources and use of apps among pregnant women is relatively limited., Objective: The aim of this study is to map the current information resources and the use of pregnancy apps among pregnant women in Flanders., Methods: A cross-sectional study was conducted, using a semistructured survey (April-June 2019) consisting of four different domains: (1) demographics; (2) use of devices; (3) sources of information; and (4) use of pregnancy apps. Women were recruited by social media, flyers, and paper questionnaires at prenatal consultations. Statistical analysis was mainly focused on descriptive statistics. Differences in continuous and categorical variables were tested using independent Student t tests and chi-square tests. Correlations were investigated between maternal characteristics and the women's responses., Results: In total, 311 women completed the entire questionnaire. Obstetricians were the primary source of information (268/311, 86.2%) for pregnant women, followed by websites/internet (267/311, 85.9%) and apps (233/311, 74.9%). The information that was most searched for was information about the development of the baby (275/311, 88.5%), discomfort/complaints (251/311, 80.7%) and health during pregnancy (248/311, 79.7%), administrative/practical issues (233/311, 74.9%), and breastfeeding (176/311, 56.6%). About half of the women (172/311, 55.3%) downloaded a pregnancy app, and primarily searched app stores (133/311, 43.0%). Pregnant women who are single asked their mothers (22/30, 73.3%) or other family members (13/30, 43.3%) for significantly more information than did married women (mother [in law]: 82/160, 51.3%, P=.02; family members: 35/160, 21.9%, P=.01). Pregnant women with lower education were significantly more likely to have a PC or laptop than those with higher education (72/73, 98.6% vs 203/237, 85.5%; P=.008), and to consult other family members for pregnancy information (30/73, 41.1% vs 55/237, 23.1%; P<.001), but were less likely to consult a gynecologist (70/73, 95.9% vs 198/237, 83.5%; P=.001). They also followed more prenatal sessions (59/73, 80.8% vs 77/237, 32.5%; P=.04) and were more likely to search for information regarding discomfort/complaints during pregnancy (65/73, 89% vs 188/237, 79.5%; P=.02). Compared to multigravida, primigravida were more likely to solicit advice about their pregnancy from other women in their social networks (family members: primigravida 44/109, 40.4% vs multigravida 40/199, 20.1%; P<.001; other pregnant women: primigravida 58/109, 53.2% vs multigravida 80/199, 40.2%; P<.03)., Conclusions: Health care professionals need to be aware that apps are important and are a growing source of information for pregnant women. Concerns rise about the quality and safety of those apps, as only a limited number of apps are subjected to an external quality check. Therefore, it is important that health care providers refer to high-quality digital resources and take the opportunity to discuss digital information with pregnant women., (©Dorien Lanssens, Inge M Thijs, Pauline Dreesen, Ann Van Hecke, Pascal Coorevits, Gitte Gaethofs, Joyce Derycke, Inge Tency.

Introduction: Evidence-based practice (EBP) leads to improved health outcomes and reduces variability in the quality of care. However, literature on the knowledge, attitudes and use of EBP among midwives is scarce internationally and in Belgium., Methods: A cross-sectional study using an online semi-structured questionnaire explored practice, attitudes and barriers on EBP and clinical practice guidelines. Midwives (n=251) working in university and non-university hospitals, primary care, and midwifery education, in Flanders (Belgium) were included., Results: Midwives with a Master's degree (57.7% vs 37.8%; p=0.004), ≤15 years since graduation (50.8% vs 35.5%; p=0.015) and aged <40 years (49.7% vs 34.6%; p=0.02), had better knowledge of the EBP-definition. The majority searched for literature (80.1%), mainly evidence-based (EB) clinical practice guidelines (50.6%), randomized controlled trials (45.0%) and systematic reviews (43.0%). Midwives found EBP necessary and realistic to apply in daily practice and support decision-making. They were willing to improve EBP-knowledge and skills but assumed to be competent in providing evidence-based care. Most respondents were convinced of the importance of EB clinical practice guidelines but did not believe guidelines facilitated their practices or enabled them to consider patient preferences adequately. Half of the midwives (55.8%) experienced barriers to EB clinical practice guideline use, mainly lack of time (35.9%), access (19.5%), and support (17.9%)., Conclusions: Although midwives showed a positive attitude towards EBP, education programs to promote EBP and improve EBP-related knowledge and skills are needed. Future efforts should focus on developing strategies for overcoming barriers and enhancing the consistency of EBP implementation., Competing Interests: The authors have completed and submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest and none was reported., (© 2022 Lanssens D. et al.)
