Counseling pregnant women on calcium: effects on calcium intake.

Objectives: To evaluate the effect of incorporating calcium advice into early pregnancy counseling on calcium intake during pregnancy in the Netherlands.

Methods: A multicenter prospective before-after cohort study was conducted introducing risk-based care including calculating individual pre-eclampsia risk. Part of the intervention was to incorporate calcium advice into routine counseling.

Adherence rates to a prediction tool identifying women with an increased gestational diabetes risk: An implementation study.

Objective: The best screening strategy for gestational diabetes mellitus (GDM) remains a topic of debate. Several organizations made a statement in favor of universal screening, but the volume of oral glucose tolerance tests (OGTT) required may burden healthcare systems. As a result, many countries still rely on selective screening using a checklist of risk factors, but reported diagnostic characteristics vary.

External validation of a prediction model on vaginal birth after caesarean in a The Netherlands: a prospective cohort study.

Objectives: Discussing the individual probability of a successful vaginal birth after caesarean (VBAC) can support decision making. The aim of this study is to externally validate a prediction model for the probability of a VBAC in a Dutch population.

Methods: In this prospective cohort study in 12 Dutch hospitals, 586 women intending VBAC were included.

Impact on perinatal health and cost-effectiveness of risk-based care in obstetrics: a before-after study.

Background: Obstetric health care relies on an adequate antepartum risk selection. Most guidelines used for risk stratification, however, do not assess absolute risks. In 2017, a prediction tool was implemented in a Dutch region.

External validation and clinical utility of prognostic prediction models for gestational diabetes mellitus: A prospective cohort study.

Introduction: We performed an independent validation study of all published first trimester prediction models, containing non-invasive predictors, for the risk of gestational diabetes mellitus. Furthermore, the clinical potential of the best performing models was evaluated.

Material And Methods: Systemically selected prediction models from the literature were validated in a Dutch prospective cohort using data from Expect Study I and PRIDE Study.
