ABSTRACT
BACKGROUND: Older people receive care from multiple providers which often results in a lack of coordination. The Information and Communication Technology (ICT) enabled value-based methodology for integrated care (ValueCare) project aims to develop and implement efficient outcome-based, integrated health and social care for older people with multimorbidity, and/or frailty, and/or mild to moderate cognitive impairment in seven sites (Athens, Greece; Coimbra, Portugal; Cork/Kerry, Ireland; Rijeka, Croatia; Rotterdam, the Netherlands; Treviso, Italy; and Valencia, Spain). We will evaluate the implementation and the outcomes of the ValueCare approach. This paper presents the study protocol of the ValueCare project; a protocol for a pre-post controlled study in seven large-scale sites in Europe over the period between 2021 and 2023. METHODS: A pre-post controlled study design including three time points (baseline, post-intervention after 12 months, and follow-up after 18 months) and two groups (intervention and control group) will be utilised. In each site, (net) 240 older people (120 in the intervention group and 120 in the control group), 50-70 informal caregivers (e.g. relatives, friends), and 30-40 health and social care practitioners will be invited to participate and provide informed consent. Self-reported outcomes will be measured in multiple domains; for older people: health, wellbeing, quality of life, lifestyle behaviour, and health and social care use; for informal caregivers and health and social care practitioners: wellbeing, perceived burden and (job) satisfaction. In addition, implementation outcomes will be measured in terms of acceptability, appropriateness, feasibility, fidelity, and costs. To evaluate differences in outcomes between the intervention and control group (multilevel) logistic and linear regression analyses will be used. Qualitative analysis will be performed on the focus group data. DISCUSSION: This study will provide new insights into the feasibility and effectiveness of a value-based methodology for integrated care supported by ICT for older people, their informal caregivers, and health and social care practitioners in seven different European settings. TRIAL REGISTRATION: ISRCTN registry number is 25089186 . Date of trial registration is 16/11/2021.

INTRODUCTION: Blood pressure levels during pregnancy are important risk factors for gestational hypertensive disorders. Non-pregnant women from ethnic minority groups are found to have higher blood pressure levels compared to white women. Little is known about variation in blood pressure development during pregnancy across different ethnic groups. OBJECTIVES: To investigate ethnic differences in blood pressure levels in each trimester of pregnancy and the risk of gestational hypertensive disorders and the degree to which such differences can be explained by education and lifestyle related factors. METHODS: The study included 6215 women participating in a population-based prospective cohort study from early pregnancy onwards in Rotterdam, The Netherlands. Ethnicity was assessed at enrolment. Blood pressure was measured in each trimester. Information about gestational hypertensive disorders was available from medical records. Lifestyle factors included smoking, alcohol, caffeine intake, folic acid supplementation, sodium and energy intake, body mass index and maternal stress. Associations and explanatory pathways were investigated using linear and logistic regression analysis. RESULTS: Dutch pregnant women had higher systolic blood pressure levels as compared to women in other ethnic groups in each trimester of pregnancy. Compared to Dutch women, Turkish and Moroccan women had lower diastolic blood pressure levels in each trimester. These differences remained after adjusting for education and lifestyle factors. Turkish and Moroccan women had a lower risk of gestational hypertension as compared to Dutch women (OR 0.32; 95% CI: 0.18, 0.58 and OR 0.28; 95% CI: 0.14, 0.58) and Cape Verdean women had an elevated risk of preeclampsia (OR 2.22; 95% CI: 1.22, 4.07). Differences could not be explained by education or lifestyle. CONCLUSION: Substantial ethnic differences were observed in blood pressure levels in each trimester of pregnancy and risk of gestational hypertensive disorders. A wide range of potential explanatory variables could not explain these differences.
ABSTRACT
BACKGROUND AND AIMS: Periconception folic acid supplementation may influence early placentation processes and thereby the occurrence of hypertensive pregnancy disorders. For this reason we examined the associations between periconception folic acid supplementation and uteroplacental vascular resistance, blood pressure, and the risks of gestational hypertension and preeclampsia, in 5993 pregnant women, participating in a population-based cohort study. METHODS AND RESULTS: Folic acid supplementation was assessed by questionnaire. Mean pulsatility index (PI) and resistance index (RI) of the uterine (UtA) and umbilical arteries (UmA) were measured by Doppler ultrasound in mid- and late pregnancy. Systolic and diastolic blood pressures (SBP, DBP) were measured in early, mid- and late pregnancy. Compared to women who did not use folic acid, preconception folic acid users had a slightly lower UtA-RI in mid-pregnancy [ß -0.02, 95% confidence interval (CI) -0.03, -0.01] and late pregnancy [ß -0.02, 95% CI -0.03, -0.001], a lower UtA-PI in mid-pregnancy [ß -0.06, 95% CI -0.1, -0.03] and late pregnancy [ß -0.03, 95% CI -0.05, -0.01], as well as tendencies towards a lower UmA-PI in mid-pregnancy [ß -0.02, 95% CI -0.04, -0.001] and late pregnancy [ß -0.01, 95% CI -0.02, 0.01]. Additionally, these women had slightly higher SBP and DBP throughout pregnancy. Neither the patterns of blood-pressure change during pregnancy, nor the risk of gestational hypertension and preeclampsia differed between the folic acid categories. CONCLUSION: Periconception folic acid supplementation is associated with lower uteroplacental vascular resistance and higher blood pressures during pregnancy. The effects are small and within physiologic ranges and seem not associated with the risk of hypertensive pregnancy disorders.
