Models of Risk Selection in Maternal and Newborn Care: Exploring the Organization of Tasks and Responsibilities of Primary Care Midwives and Obstetricians in Risk Selection across The Netherlands.

An effective system of risk selection is a global necessity to ensure women and children receive appropriate care at the right time and at the right place. To gain more insight into the existing models of risk selection (MRS), we explored the distribution of different MRS across regions in The Netherlands, and examined the relation between MRS and primary care midwives' and obstetricians' satisfaction with different MRS. We conducted a nationwide survey amongst all primary midwifery care practices and obstetrics departments. The questionnaire was completed by 312 (55%) primary midwifery care practices and 53 (72%) obstetrics departments. We identified three MRS, which were distributed differently across regions: (1) primary care midwives assess risk and initiate a consultation or transfer of care without discussing this first with the obstetrician, (2) primary care midwives assess risk and make decisions about consultation or transfer of care collaboratively with obstetricians, and (3) models with other characteristics. Across these MRS, variations exist in several aspects, including the routine involvement of the obstetrician in the care of healthy pregnant women. We found no significant difference between MRS and professionals' level of satisfaction. An evidence- and value-based approach is recommended in the pursuit of the optimal organization of risk selection. This requires further research into associations between MRS and maternal and perinatal outcomes, professional payment methods, resource allocation, and the experiences of women and care professionals.

Associations between phenotypes of preeclampsia and thrombophilia.

OBJECTIVES: Preeclampsia complicates 2-8% of all pregnancies. Studies on the association of preeclampsia with thrombophilia are conflicting. Clinical heterogeneity of the disease may be one of the explanations. The present study addresses the question whether different phenotypes of preeclampsia are associated with thrombophilia factors. Study design We planned a retrospective cohort study. From 1985 until 2010 women with preeclampsia were offered postpartum screening for the following thrombophilia factors: anti-phospholipid antibodies, APC-resistance, protein C deficiency and protein S deficiency, hyperhomocysteineamia, factor V Leiden and Prothrombin gene mutation. Hospital records were used to obtain information on phenotypes of the preeclampsia and placental histology. RESULTS: We identified 844 women with singleton pregnancies who were screened for thrombophilia factors. HELLP complicated 49% of pregnancies; Fetal growth restriction complicated 61% of pregnancies. Early delivery (<34th week) occurred in 71% of pregnancies. Any thrombophilia factor was present in 29% of the women. Severe preeclampsia was associated with protein S deficiency (p=0.01). Fetal growth restriction was associated with anti-phospholipid antibodies (p<0.01). Early onset preeclampsia was associated with anti-phospholipid antibodies (p=0.01). Extensive placental infarction (>10%) was associated with anti-phospholipid antibodies (p<0.01). Low placental weight (<5th percentile) was associated with hyperhomocysteineamia (p=0.03). No other associations were observed. CONCLUSIONS: Early onset preeclampsia, especially if complicated by fetal growth restriction, are associated with anti-phospholipid antibodies. Other phenotypes of preeclampsia, especially HELLP syndrome, were not associated with thrombophilia. We advise only to test for anti-phospholipid antibodies after early onset preeclampsia, especially if complicated by fetal growth restriction. We suggest enough evidence is presented to justify no further studies are needed.

PP045. Different associations between phenotypes of preeclampsia and thrombophilias.

INTRODUCTION: Studies on the association of preeclampsia (PE) with thrombophilias (TRPH) are conflicting. Clinical heterogeneity of PE may be one of the explanations. OBJECTIVES: The present study addresses the question whether different phenotypes of PE are associated with subtypes of TRPH. METHODS: In this retrospective cohort study between 1985 until 2010 women with PE were offered postpartum screening for the following TRPH: anti-phospholipid antibodies (APA), APC-resistance, protein C deficiency and protein S deficiency (PSD), hyperhomocysteinemia (HCY), factor V Leiden and Prothrombin gene mutation. RESULTS: 890 Women with PE were screened for TRPH. 49% Also had HELLP, 60% had IUGR, 71% delivered before the 34th week. One or more TRPH factors were present in 31% of the women. Severe PE was associated with PSD (p=0.01). IUGR (p<0.01) was associated with APA (p<0.01) and PSD (P=0.03). Early onset PE was associated with APA (P, 0.01). More than 10% of placental infarction was associated with APA (p<0.01). Placental weight below the 5th percentile was associated with HCY (p=0.03). Other phenotypes of PE and TRPH were not associated. CONCLUSION: Severe and early onset PE, especially if complicated by IUGR, are associated with APA and PSD. Other phenotypes of PE, especially HELLP syndrome, were not associated with TRPH. We advise to screen for APA and PSD after severe and early onset PE, especially if complicated by IUGR. We do not recommend screening for TRPH in other phenotypes of PE.

Motivators and barriers to a healthy postpartum lifestyle in women at increased cardiovascular and metabolic risk: a focus-group study.

OBJECTIVE: To describe the motivators and barriers to the adoption of a healthy postpartum lifestyle after a pregnancy complicated by preeclampsia, intrauterine growth restriction, and/or gestational diabetes. METHODS: Thirty-six women with complicated pregnancies participated in six focus-group interviews that aimed to explore the perceptions of modifiable determinants of postpartum lifestyle. RESULTS: Although women expressed that they intended to live a healthy postpartum lifestyle, it was generally not achieved. The motivators included improving their own current health condition as well as modeling a healthy lifestyle for their children. Important barriers were reported to be lack of knowledge, poor recovery, and lack of professional support after delivery. CONCLUSIONS: The reported motivators and barriers can be used to develop a postpartum lifestyle intervention.

Postpartum physical activity after preeclampsia.

OBJECTIVE: After mild and severe preeclampsia, to assess whether women meet the physical activity recommendation at 3 and 6months postpartum, and whether demographic, obstetric and anthropometric characteristics, mental health, and health-related quality of life are associated with less physical activity than recommended. STUDY DESIGN: Prospective cohort study. MAIN OUTCOME MEASURES: Self-reported physical activity in MET-min/week, percentage of women who fail to meet the physical activity recommendation. METHODS: Of the 255 women diagnosed with preeclampsia invited to participate in this prospective cohort study, 174 (68%) provided informed consent. Analyses were restricted to 141 participants who completed the short form of the International Physical Activity Questionnaire at 3 and/or 6months postpartum. Logistic regression analysis was used to evaluate changes in physical activity level over time, and to establish which variables were associated with failure to meet the postpartum physical activity recommendation. RESULTS: At both 3 and 6months postpartum, 38% of women failed to meet the physical activity recommendation. Failure was associated with severe preeclampsia, cesarean section, admission to the neonatal intensive care unit, low gestational age at delivery, and low birth weight (all p<0.05). CONCLUSIONS: There seems to be a need to stimulate physical activity in about one third of women after a pregnancy complicated by preeclampsia, particularly in case of severe preeclampsia and other adverse pregnancy outcomes. Tailored lifestyle interventions are needed for women who fail to meet the recommendation.

Poor health-related quality of life after severe preeclampsia.

BACKGROUND: Preeclampsia is a major complication of pregnancy associated with increased maternal morbidity and mortality, and adverse birth outcomes. The objective of this study was to describe changes in all domains of health-related quality of life between 6 and 12 weeks postpartum after mild and severe preeclampsia; to assess the extent to which it differs after mild and severe preeclampsia; and to assess which factors contribute to such differences. METHODS: We conducted a prospective multicenter cohort study of 174 postpartum women who experienced preeclampsia, and who gave birth between February 2007 and June 2009. Health-related quality of life was measured at 6 and 12 weeks postpartum by the RAND 36-item Short-Form Health Survey (SF-36). The population for analysis comprised women (74%) who obtained scores on the questionnaire at both time points. RESULTS: Women who experienced severe preeclampsia had a lower postpartum health-related quality of life than those who had mild preeclampsia (all p < 0.05 at 6 wk postpartum). Quality of life improved on almost all SF-36 scales from 6 to 12 weeks postpartum (p < 0.05). Compared with women who had mild preeclampsia, those who experienced severe preeclampsia had a poorer mental quality of life at 12 weeks postpartum (p < 0.05). Neonatal intensive care unit admission and perinatal death were contributing factors to this poorer mental quality of life. CONCLUSIONS: Obstetric caregivers should be aware of poor health-related quality of life, particularly mental health quality of life in women who have experienced severe preeclampsia (especially those confronted with perinatal death or their child's admission to a neonatal intensive care unit), and should consider referral for postpartum psychological care.

Symptoms of post-traumatic stress after preeclampsia.

This study describes the prevalence of postpartum post-traumatic stress disorder (PTSD) based on the DSM-IV criteria, including its symptoms of intrusion, avoidance and hyperarousal after pregnancies complicated by preeclampsia, and examines which variables are associated with PTSD and its symptoms. Women whose pregnancies were complicated by preeclampsia completed the Self-Rating Inventory for PTSD at 6 and 12 weeks postpartum: 149 women completed this questionnaire on at least one time point. Logistic regression analyses were used to examine associations with PTSD and its symptoms. Results showed that the prevalence of PTSD was 8.6% at 6 weeks, and 5.1% at 12 weeks postpartum; 21.9% of the study sample experienced postpartum symptoms of intrusion at 6 weeks postpartum (11.7% at 12 weeks), 9.4% symptoms of avoidance (8.0% at 12 weeks), and 28.9% symptoms of hyperarousal (20.4% at 12 weeks). Younger age, severe preeclampsia, cesarean section, lower gestational age, lower birth weight, admission to the neonatal intensive care unit, and perinatal death were found to be associated with PTSD and its symptoms. There was a relatively high prevalence of postpartum symptoms of PTSD among women after preeclampsia. The prevalence was highest among younger women who experienced more adverse pregnancy outcomes.

Postpartum depression after mild and severe preeclampsia.

OBJECTIVE: To describe the prevalence of postpartum depressive symptoms after preeclampsia, to assess the extent to which the prevalence of postpartum depressive symptoms differs after mild and severe preeclampsia, and to investigate which factors contribute to such differences. METHODS: Women diagnosed with preeclampsia (n=161) completed the Edinburgh Postnatal Depression Scale (EPDS) at 6, 12, or 26 weeks postpartum. Multiple logistic regression analysis was used to investigate the association between severity of preeclampsia, contributing factors and postpartum depression (PPD) (1) at any time during the first 26 weeks postpartum and (2) accounting for longitudinal observations at three time points. RESULTS: After mild preeclampsia, 23% reported postpartum depressive symptoms at any time up to 26 weeks postpartum compared to 44% after severe preeclampsia (unadjusted odds ratio [OR] 2.65, 95% confidence interval [CI] 1.16-6.05) for depression at any time up to 26 weeks postpartum (unadjusted OR 2.57, 95% CI, 1.14-5.76) while accounting for longitudinal observations. Admission to the neonatal intensive care unit (NICU) (adjusted OR 3.19, 95% CI 1.15-8.89) and perinatal death (adjusted OR 2.96, 95% CI 1.09-8.03) contributed to this difference. CONCLUSIONS: It appears that not the severity of preeclampsia itself but rather the consequences of the severity of the disease (especially admission to the NICU and perinatal death) cause postpartum depressive symptoms. Obstetricians should be aware of the high risk of postpartum depressive symptoms after severe preeclampsia, particularly among women whose infant has been admitted to the NICU or has died.

Preferences for postpartum lifestyle counseling among women sharing an increased cardiovascular and metabolic risk: a focus group study.

OBJECTIVE: To describe women's preferences for postpartum lifestyle counseling after a pregnancy complicated by preeclampsia, intrauterine growth restriction, and/or gestational diabetes. METHODS: Thirty-six women who had experienced these pregnancy complications participated in six focus group interviews. RESULTS: All women expressed a need for participation in postpartum lifestyle counseling. They preferred participation to be tailored to individual preferences. A combination of face-to-face counseling supported by computer-tailored lifestyle advice appealed to them. CONCLUSION: Postpartum lifestyle counseling aimed at these women should be tailored to individual needs and preferences.

Effect of postpartum lifestyle interventions on weight loss, smoking cessation, and prevention of smoking relapse: a systematic review.

UNLABELLED: Postpartum lifestyle interventions are recommended for women after pregnancies complicated by preeclampsia, intrauterine growth restriction, and/or gestational diabetes, since they are at increased cardiovascular risk. To identify potential intervention strategies to reduce this risk, a systematic review of the literature is presented on the effectiveness of postpartum lifestyle interventions aimed at weight loss, smoking cessation, and smoking relapse prevention. The main characteristics of these postpartum lifestyle interventions are briefly described. The PubMed, Embase, Web of Science, PsychInfo, and Cinahl databases were searched for studies on the effects of postpartum lifestyle interventions on weight loss, and smoking cessation or prevention of smoking relapse, initiated for up to 1 year postpartum. No studies on the effectiveness of postpartum lifestyle interventions after the aforementioned specific pregnancy complications were found. However, 21 studies are included that describe existing postpartum lifestyle interventions, which were applied to unselected (on the basis of pregnancy complications) postpartum women. Six of 8 weight loss interventions, 4 of 5 smoking cessation interventions, and 4 of 8 smoking relapse prevention interventions were effective. Individually tailored counseling, group counseling sessions, and use of diaries or other correspondence materials were shown to be effective. Currently, postpartum lifestyle interventions tailored specifically for women who experienced the pregnancy complications are lacking. While awaiting their development, it seems reasonable to utilize existing lifestyle interventions shown to be effective in unselected postpartum women. LEARNING OBJECTIVES: After completion of this educational activity, the obstetrician/gynecologist should be better able to: counsel patients on how to apply existing postpartum lifestyle intervention strategies aimed at weight loss, smoking cessation, and smoking relapse prevention to lower future cardiovascular risk; and educate postpartum women who have experienced preeclampsia, intra-uterine growth restriction, and/or gestational diabetes about their increased cardiovascular risk later in life. TARGET AUDIENCE: Obstetricians & Gynecologists, Family Physicians.

Resolution of hypertension and proteinuria after preeclampsia.

OBJECTIVE: To estimate the time required for hypertension and proteinuria to resolve after preeclampsia, and to estimate how this time to resolution correlates with the levels of blood pressure and proteinuria during preeclampsia and prolonging pregnancy after the development of preeclampsia. METHODS: This is a historic prospective cohort study of 205 preeclamptic women who were admitted between 1990 and 1992 at the Erasmus MC Medical Centre, Rotterdam, The Netherlands. Data were collected at 1.5, 3, 6, 12, 18, and 24 months after delivery. Hypertension was defined as a blood pressure 140/90 mm Hg or higher or use of antihypertensive drugs. Proteinuria was defined as 0.3 g/d or more. Resolution of hypertension and proteinuria were analyzed with the Turnbull extension to the Kaplan-Meier procedure. Correlations were calculated with an accelerated failure time model. RESULTS: At 3 months postpartum, 39% of women still had hypertension, which decreased to 18% at 2 years postpartum. Resolution time increased by 60% (P<.001) for every 10-mm Hg increase in maximal systolic blood pressure, 40% (P=.044) for every 10-mm Hg increase in maximal diastolic blood pressure, and 3.6% (P=.001) for every 1-day increase in the diagnosis-to-delivery interval. At 3 months postpartum, 14% still had proteinuria, which decreased to 2% at 2 years postpartum. Resolution time increased by 16% (P=.001) for every 1-g/d increase in maximal proteinuria. Gestational age at onset of preeclampsia was not correlated with resolution time of hypertension and proteinuria. CONCLUSION: The severity of preeclampsia and the time interval between diagnosis and delivery are associated with postpartum time to resolution of hypertension and proteinuria. After preeclampsia, it can take up to 2 years for hypertension and proteinuria to resolve. Therefore, the authors suggest that further invasive diagnostic tests for underlying renal disease may be postponed until 2 years postpartum. LEVEL OF EVIDENCE: III.
