The impact of pre-eclampsia definitions on the identification of adverse outcome risk in hypertensive pregnancy - analyses from the CHIPS trial (Control of Hypertension in Pregnancy Study).

OBJECTIVE: To examine the association between pre-eclampsia definition and pregnancy outcome. DESIGN: Secondary analysis of Control of Hypertension in Pregnancy Study (CHIPS) trial data. SETTING: International multicentre randomised controlled trial (RCT). POPULATION: In all, 987 women with non-severe non-proteinuric pregnancy hypertension. METHODS: We evaluated the association between pre-eclampsia definitions and adverse pregnancy outcomes, stratified by hypertension type and blood pressure control. MAIN OUTCOME MEASURES: Main CHIPS trial outcomes: primary (perinatal loss or high-level neonatal care for >48 hours), secondary (serious maternal complications), birthweight <10th centile, severe maternal hypertension, delivery at <34 or <37 weeks, and maternal hospitalisation before birth. RESULTS: Of 979/987 women with informative data, 280 (28.6%) progressed to pre-eclampsia defined restrictively by new proteinuria, and 471 (48.1%) to pre-eclampsia defined broadly as proteinuria or one/more maternal symptoms, signs or abnormal laboratory tests. The broad (versus restrictive) definition had significantly higher sensitivities (range 62-79% versus 36-50%), lower specificities (range 53-65% versus 72-82%), and similar or higher diagnostic odds ratios and 'true-positive' to 'false-positive' ratios. Stratified analyses showed similar results. Addition of available fetoplacental manifestations (stillbirth or birthweight <10th centile) to the broad pre-eclampsia definition improved sensitivity (74-87%). CONCLUSIONS: A broad (versus restrictive) pre-eclampsia definition better identifies women who develop adverse pregnancy outcomes. These findings should be replicated in a prospective study within routine healthcare to ensure that the anticipated increase in surveillance and intervention in a larger number of women with pre-eclampsia is associated with improved outcomes, reasonable costs and congruence with women's values. TWEETABLE ABSTRACT: A broad (versus restrictive) pre-eclampsia definition better identifies the risk of adverse pregnancy outcomes.

The brain study: Cognition, quality of life and social functioning following preeclampsia; An observational study.

OBJECTIVES: Previously preeclamptic women may express cognitive difficulties, which have largely been unappreciated or attributed to stresses of a complicated pregnancy. This study aimed to explore the scope of perceived neurocognitive and psychosocial problems as well as quality of life following preeclampsia. STUDY DESIGN: Observational study. Through website promotion and e-mail, registrants of the USA-based Preeclampsia Foundation who experienced preeclampsia in the past 20years were invited to complete a web-based survey. Participants were requested to ask an acquaintance that had a normotensive pregnancy to also complete the survey (controls). MAIN OUTCOME MEASURES: The Cognitive Failures Questionnaire (CFQ), abbreviated WHO Quality Of Life questionnaire (WHOQOL-BREF), Social Functioning Questionnaire (SFQ) and Breslau Short Screening Scale for DSM-IV Posttraumatic Stress Disorder were used in the survey. Analysis was performed using Mann-Whitney U tests and linear regression. RESULTS: 966 cases and 342 controls completed the survey (median age 34, median time since first pregnancy 4 vs. 5years). Cases scored significantly worse on CFQ (median 35 vs. 27), WHOQOL-BREF domains physical health (15 vs. 17), psychological (13 vs. 15), social relationships (13 vs. 15) and environment (15 vs. 16), and SFQ (8 vs. 7). All p<0.001. Multivariable analysis showed an independent significant effect of eclampsia on CFQ and of migraine on all questionnaires and the effect of preeclampsia was still present after adjustment for confounders. Posttraumatic stress symptoms accounted for part of the relationships. CONCLUSIONS: Previously preeclamptic women appear to perceive more cognitive and social problems, and report poorer quality of life compared to a group of women with normotensive pregnancies. Research relating to the origin and management of these issues is needed.

OS107. Pregnancies involving hypertensive disorders of pregnancy are associated with posttraumatic stress disorder.

INTRODUCTION: Pregnancies complicated by hypertensive disorders of pregnancy (HDP) can result in adverse perinatal outcomes leading to additional and unexpected levels of stress for the families involved. OBJECTIVES: Our primary aim was to examine if HDP is associated with posttraumatic stress disorder (PTSD). METHODS: We analyzed data collected through an online survey by the Preeclampsia Foundation on PTSD symptoms using the Breslau Short Screening Scale for DSM-IV. We compared participant characteristics between women with and without PTSD using chi-square tests for discrete variables and t-tests for continuous variables. Univariate and multivariable logistic regression analyses were used to examine the outcome of PTSD and identify possible risk factors associated with HDP. RESULTS: We surveyed 1448 women (1076 HDP, 372 controls). After adjusting for psychiatric illness or mood disorder, parity, and age at affected pregnancy, we found that women with HDP were more than four times as likely to screen positive for PTSD (OR = 4.64, 95% CI: 3.37-6.39) when compared to women without HDP. Additionally, we found that PTSD symptoms increase with severity of HDP. When stratifying by severity, we found that women with gestational hypertension and preeclampsia were three and a half times more likely (OR=3.45, 95% CI: 1.70-7.00 and OR=3.48, 95% CI: 2.45-4.96, respectively); women with hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome were nearly six times as likely (OR=5.76, 95% CI: 3.97-8.36), and women with eclampsia were almost ten times as likely to screen positive for PTSD (OR=9.76, 95% CI: 5.45-17.49) when compared to women without HDP. CONCLUSION: Pregnancies complicated by HDP are associated with increased risk of PTSD, with risk of PTSD increasing as severity of HDP increases. Medical practitioners should be aware of this association and consider screening women with HDP for signs of PTSD at their first postpartum visit. Those who screen positive could then be referred for a confirmatory diagnosis and, if needed, subsequent supportive care.

OS101. The brain study: cognition, quality of life and social functioning following preeclampsia.

INTRODUCTION: Previously preeclamptic women may express cognitive difficulties, which have largely been ignored or attributed to the stresses of a complicated pregnancy. OBJECTIVES: This study aimed to identify the scope of neurocognitive and psychosocial problems following preeclampsia. METHODS: Through website promotion and a mass e-mail members of the USA-based Preeclampsia Foundation who experienced preeclampsia in the past 20 years were invited to complete a web-based survey, consisting of a questionnaire about current and past medical health, the Cognitive Failures Questionnaire (CFQ), the abbreviated WHO Quality Of Life questionnaire (WHOQOL-BREF), and the Social Functioning Questionnaire (SFQ). Participants were stimulated to ask a friend who had a normotensive pregnancy to complete the survey as well (controls). Women with current or past neurological conditions were excluded. Analysis was performed using Mann Whitney U test and linear regression. RESULTS: 966 cases and 342 controls were included. Median age was 34, median time since first pregnancy 4 and 5 years respectively. Cases scored significantly worse on all three questionnaires, and more often underwent psychiatric therapy, currently or in the past. There was a significant effect of migraine on all questionnaires and of eclampsia on CFQ score. Cronbach's alphas were >0.7, indicating good internal consistency of the questionnaires. Results are expressed as median (range) or number (percentage) (∗)p<.001. CONCLUSION: Previously preeclamptic women report more cognitive and social problems, and worse quality of life compared to women who had normotensive pregnancies. Health care providers and patients should be aware of this so that affected women may receive recognition, psychological care and escape from the ignorance of their environment. Our findings may stimulate research relating to the origin and management of these important issues.
