Sleep Quality in Individuals with and without Persistent Postpartum Hypertension.

OBJECTIVE: This study aimed to compare sleep quality at 1 year postpartum following a hypertensive disorder of pregnancy (HDP) among individuals with persistent postpartum hypertension (HTN) compared with those with normal blood pressures (BPs). STUDY DESIGN: We combined data from the Heart Health 4 New Moms pilot randomized trial (n = 118) and the Pathways prospective cohort study (n = 36). Individuals with a singleton pregnancy complicated by gestational HTN or preeclampsia underwent a research study visit at a mean 48.7 ± 9.5 weeks postpartum with standardized BP measurement and assessment of subjective sleep quality with the Pittsburgh Sleep Quality Index (PSQI). Persistent postpartum HTN was defined as Stage 1 HTN or greater (mean systolic BP ≥ 130 mm Hg or mean diastolic BP ≥ 80 mm Hg over three measurements at rest) or requiring antihypertensive medication. Statistical analysis was performed using univariate and multivariable logistic regression analyses. RESULTS: Of 154 individuals with an HDP included in the analysis, 84 (55%) were normotensive at 1 year postpartum and 70 (45%) had persistent postpartum HTN. Individuals with persistent postpartum HTN were more likely to be older, self-identify as Black race, have higher prepregnancy and 1-year postpartum body mass index (BMI), be multiparous, and deliver at an earlier gestational age. The mean global PSQI score was 8.7 ± 3.7, with 81% reporting poor sleep (PSQI > 5), and scores were higher among individuals who were persistently hypertensive (9.6 ± 3.5) compared with those who were normotensive at 1 year postpartum (7.9 ± 3.6), p < 0.01. Findings were unchanged in a multivariable model adjusting for age, self-reported race, prepregnancy BMI, and parity. CONCLUSION: Following an HDP, individuals reported poor sleep quality at 1 year postpartum. Individuals with persistent postpartum HTN reported lower sleep quality, suggesting that sleep behavior may be a target for intervention to improve maternal cardiovascular health following an HDP. KEY POINTS: · After an HDP, poor sleep quality was common at 1 year postpartum.. · Those with persistent postpartum HTN reported worse sleep quality at 1 year postpartum.. · Sleep behavior may be a target for intervention to improve maternal cardiovascular health..

The effect of a neonatal sleep intervention on maternal postpartum hypertension: a randomized trial.

BACKGROUND: In nonpregnant adults, poor sleep is associated with higher blood pressure. Poor sleep is common in the postpartum period and is often attributed to infant caretaking needs. However, its effects on cardiovascular health in individuals with a hypertensive disorder of pregnancy are unknown. OBJECTIVE: This study aimed to determine the effect of a neonatal sleep intervention on maternal postpartum blood pressure in individuals with a hypertensive disorder of pregnancy. STUDY DESIGN: In this single-institution pilot randomized controlled trial from July 2021 to March 2022, 110 individuals with a hypertensive disorder of pregnancy were randomized to receive a neonatal sleep intervention (SNOO responsive bassinet) plus usual care of safe sleep education (n=54) or usual care alone (n=56). Remote follow-up visits were conducted at 1 week, 6 weeks, and 4 months after delivery and involved blood pressure and weights, sleep and mood questionnaires, and self-reported infant and maternal sleep logs. Based on institutional data, the sample size had 80% power to detect a 4.5-mm Hg difference in the primary outcome of mean arterial pressure at 6 weeks after delivery. RESULTS: Baseline characteristics were similar between the arms. At 1 week after delivery, the intervention arm had lower mean arterial pressure and less antihypertensive medication use than the control arm (99±10 vs 103±7 mm Hg [P=.04] and 23% vs 35% [P=.15], respectively). At 6 weeks after delivery, mean arterial pressure was similar between arms (93±8 vs 94±8 mm Hg; P=.54), but there was a lower rate of antihypertensive use in the intervention arm (15% vs 26%; P=.19). Scores from maternal sleep and mood questionnaires at 6 weeks after delivery and self-reported infant and maternal sleep duration at 6 weeks and 4 months after delivery were similar between arms (P>.05). CONCLUSION: The SNOO responsive bassinet as a neonatal sleep intervention did not result in improved mean arterial pressure at 6 weeks after delivery after hypertensive disorders of pregnancy.

Reproductive Decision-Making Capacity in Women With Psychiatric Illness: A Systematic Review.

BACKGROUND: Decision-making capacity can be affected by psychiatric illness. Women who have psychiatric illness who make decisions about their reproductive health may require evaluation of their decision-making capacity. OBJECTIVE: This article aims to characterize existing literature about capacity evaluations in women with psychiatric illness making reproductive decisions. METHODS: We conducted a systematic review searching PubMed, EMBASE, Ovid PsycINFO, and ClinicalTrials.gov databases through July 2020. Articles were evaluated for relevance to inclusion criteria, first by title and abstract screening then by reading the full text of articles. Our inclusion criteria were case reports and studies that involved women of childbearing age with psychiatric illness making obstetrical decisions for whom decision-making capacity was evaluated. We qualitatively analyzed our data by examining themes within the studies, such as the circumstances of the referral and characteristics of reproductive decision-making. We also collected information about the clinical circumstances, such as the clinical setting (e.g., inpatient or outpatient, in primarily psychiatric or obstetric care) and who made the determination of capacity. RESULTS: We identified 18 articles, which included 22 distinct patient cases and 27 distinct obstetrical decisions. Decisions about termination of pregnancy were most common, which were 10 of 27 decisions. Decisions about timing and mode of delivery accounted for 7 and 5 decisions, respectively. The most common psychiatric diagnosis reported was schizophrenia, which was present in 8 patients. Major depression and bipolar disorder were also frequently reported, present in 3 and 5 patients, respectively. CONCLUSION: Patients who make health care decisions must have decision-making capacity. A patient with psychiatric illness does not inherently lack capacity, and in fact, most patients with psychiatric illness have decision-making capacity. Psychiatric illness, however, can add complexity to obstetrical medical decision-making. Reasons for this complexity include the involvement of many stakeholders, the often time-sensitive nature of these decisions, and the potentially unpredictable course of psychiatric illness. Successful management of these cases involves multidisciplinary collaboration, the use of preventative ethics through advanced care planning, and identification of a guardian or surrogate decision-maker when a patient is determined to lack decision-making capacity or for a patient who has capacity through advanced care planning.

A Cost-Benefit Analysis of Low-Dose Aspirin Prophylaxis for the Prevention of Preeclampsia in the United States.

OBJECTIVE: To develop a decision model to evaluate the risks, benefits, and costs of different approaches to aspirin prophylaxis for the approximately 4 million pregnant women in the United States annually. METHODS: We created a decision model to evaluate four approaches to aspirin prophylaxis in the United States: no prophylaxis, prophylaxis per American College of Obstetricians and Gynecologists (the College) recommendations, prophylaxis per U.S. Preventive Services Task Force recommendations, and universal prophylaxis. We included the costs associated with aspirin, preeclampsia, preterm birth, and potential aspirin-associated adverse effects. TreeAge Pro 2011 was used to perform the analysis. RESULTS: The estimated rate of preeclampsia would be 4.18% without prophylaxis compared with 4.17% with the College approach in which 0.35% (n=14,000) of women receive aspirin, 3.83% with the U.S. Preventive Services Task Force approach in which 23.5% (n=940,800) receive aspirin, and 3.81% with universal prophylaxis. Compared with no prophylaxis, the U.S. Preventive Services Task Force approach would save $377.4 million in direct medical care costs annually, and universal prophylaxis would save $365 million assuming 4 million births each year. The U.S. Preventive Services Task Force approach is the most cost-beneficial in 79% of probabilistic simulations. Assuming a willingness to pay of $100,000 per neonatal quality-adjusted life-year gained, the universal approach is the most cost-effective in more than 99% of simulations. CONCLUSION: Both the U.S. Preventive Services Task Force approach and universal prophylaxis would reduce morbidity, save lives, and lower health care costs in the United States to a much greater degree than the approach currently recommended by the College.

Prevention and management of postpartum hemorrhage: a comparison of 4 national guidelines.

OBJECTIVE: The purpose of this study was to compare 4 national guidelines for the prevention and management of postpartum hemorrhage (PPH). STUDY DESIGN: We performed a descriptive analysis of guidelines from the American College of Obstetrician and Gynecologists practice bulletin, the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, the Royal College of Obstetrician and Gynaecologists (RCOG), and the Society of Obstetricians and Gynaecologists of Canada on PPH to determine differences, if any, with regard to definitions, risk factors, prevention, treatment, and resuscitation. RESULTS: PPH was defined differently in all 4 guidelines. Risk factors that were emphasized in the guidelines conferred a high risk of catastrophic bleeding (eg, previous cesarean delivery and placenta previa). All organizations, except the American College of Obstetrician and Gynecologists, recommended active management of the third stage of labor for primary prevention of PPH in all vaginal deliveries. Oxytocin was recommended universally as the medication of choice for PPH prevention in vaginal deliveries. The Royal Australian and New Zealand College of Obstetricians and Gynaecologists and RCOG recommended development of a massive transfusion protocol to manage PPH resuscitation. Recommendations for nonsurgical treatment strategies such as uterine packing and balloon tamponade varied across all guidelines. All organizations recommended transfer to a tertiary care facility for suspicion of abnormal placentation. Specific indications for hysterectomy were not available in any guideline, with RCOG recommending hysterectomy "sooner rather than later" with the assistance of a second consultant. CONCLUSION: Substantial variation exists in PPH prevention and management guidelines among 4 national organizations that highlights the need for better evidence and more consistent synthesis of the available evidence with regard to a leading cause of maternal death.

Blood gases and retinopathy of prematurity: the ELGAN Study.

OBJECTIVE: This study tested the hypothesis that preterm infants who had a blood gas derangement on at least 2 of the first 3 postnatal days are at increased risk for more severe retinopathy of prematurity (ROP). METHOD: 1,042 infants born before 28 weeks' gestational age (GA) were included. An infant was considered to be exposed if his/her blood gas measure was in the highest or lowest quartile for GA on at least 2 of the first 3 postnatal days. RESULTS: Multivariable models adjusting for confounders indicate that exposure to a PCO(2) in the highest quartile predicts ROP (stage 3, 4 or 5: OR = 1.6, 95% CI = 1.1-2.3); zone 1: 2.0, 1.1-3.6; prethreshold/threshold: 1.9, 1.2-3.0; plus disease: 1.8, 1.1-2.9). Estimates are similar for a low pH for zone 1 (2.1, 1.2-3.8), prethreshold/threshold (1.8, 1.1-2.8), but did not quite achieve statistical significance for ROP stage 3, 4, or 5 (1.4, 0.9-2.0) and plus disease (1.5, 0.9-2.4). A PaO(2) in the highest quartile for GA on at least 2 of the first 3 postnatal days was associated with a doubling of the risk of ROP in zone 1 (2.5, 1.4-4.4) and of prethreshold/threshold disease (2.1, 1.4-3.3), a 70% risk increase for plus disease (1.7, 1.04-2.8), while a 40% risk increase for ROP stage 3 or higher did not achieve statistical significance (1.4, 0.96-2.0). CONCLUSION: Infants exposed to high PCO(2), low pH and high PaO(2) appear to be at increased risk of more severe ROP.
