RESUMO
BACKGROUND: Spontaneous preterm birth significantly increases the risk for a recurrent preterm birth. Only a few identifiable clinical risk factors can be referenced in counseling for recurrent preterm birth. Furthermore, treatment using progesterone supplementation has not consistently prevented preterm birth among high-risk patients, but it may be effective in a subset of those patients. Placental pathology from a previous pregnancy may be used to predict which patients will experience a recurrent preterm birth or to identify a subset of patients more likely to respond to treatment with antenatal progesterone. OBJECTIVE: This study aimed to determine if histologic patterns are associated with recurrent preterm birth among patients with an index spontaneous preterm birth. A secondary objective was to determine if placental histologic types and/or progesterone receptor density in the decidua are associated with the response to progesterone supplementation with intramuscular 17-hydroxyprogesterone caproate. STUDY DESIGN: This was a retrospective cohort study at a single institution of women with singleton pregnancies with an index spontaneous preterm birth and a subsequent birth within the same hospital system between 2009 and 2019. Patients were included if placental pathology was available for the index spontaneous preterm birth. A logistic regression was used to determine if there were independent associations between 4 histologic types (acute inflammation, maternal vascular malperfusion, fetal vascular malperfusion, chronic inflammation) and recurrent preterm birth. For the secondary endpoint, 17-hydroxyprogesterone caproate response was defined as prolonging gestation by >3 weeks beyond the gestational age at delivery in the index pregnancy. Patients who delivered <3 weeks beyond the gestational age in the index pregnancy but at ≥39 weeks' gestation were excluded. A logistic regression was used to assess the independent association between placental histology and 17-hydroxyprogesterone caproate response. Sensitivity analyses were completed using only patients with an index birth <36 weeks' gestation, and then excluding those with medically indicated preterm birth in a subsequent pregnancy. A nested case-control immunohistochemical study was done among 20 patients with a subsequent term birth and 20 patients with a subsequent spontaneous preterm birth. The percentage of cells in the maternal decidua positive for progesterone receptors was correlated with the subsequent pregnancy outcome. RESULTS: A total of 352 patients were included. Acute inflammation was the most common histologic type seen among patients with spontaneous preterm birth (44.1%), followed by chronic inflammation (40.9%) and maternal vascular malperfusion (31.3%). No histologic type was independently associated with recurrent preterm birth. A total of 155 patients received 17-hydroxyprogesterone caproate in a second pregnancy. Low-grade acute inflammation was significantly associated with a decreased likelihood of 17-hydroxyprogesterone caproate response. Low-grade maternal vascular malperfusion among those with an index pregnancy delivered at <36 weeks' gestation was significantly associated with a more than 4 times increased likelihood of 17-hydroxyprogesterone caproate response when excluding those with a subsequent iatrogenic preterm birth. Progesterone receptor staining was not associated with recurrent preterm birth. CONCLUSION: Although acute inflammation was prevalent among spontaneous preterm births, more than half of the spontaneous preterm births were not associated with acute inflammation. Low-grade acute inflammation was associated with a significantly decreased response to 17-hydroxyprogesterone caproate supplementation. Low-grade maternal vascular malperfusion was associated with a 4-fold increased likelihood of 17-hydroxyprogesterone caproate response among those with index deliveries <36 weeks' gestation. Further work is needed to determine if placental pathologic examination can be used to target treatment in subsequent pregnancies to prevent recurrent preterm birth.

OBJECTIVE: Our objective was to assess whether variables from an index pregnancy (PG1) can be used to guide testing for gestational diabetes mellitus (GDM) in a subsequent pregnancy (PG2) and to create a risk calculator for GDM in PG2. STUDY DESIGN: This was a retrospective cohort study of patients delivering ≥2 singleton gestations at >24 weeks' gestation from June 2009 to December 2018, for whom results of a 1-hour glucose challenge test (GCT) were available from PG1. Univariable and multivariable analyses were performed to evaluate factors associated with GDM in PG2. RESULTS: In total, 4,278 patients met the inclusion criteria. Among patients with a normal 1-hour GCT (<140 mg/dL) in PG1 (n = 3,719), 3.9% were diagnosed with GDM in PG2. In multivariable analysis of this group, GDM in PG2 was associated with higher GCT in PG1 (adjusted odds ratio [aOR]: 1.05, 95% confidence interval [CI]: 1.04-1.06), large for gestational age neonate in PG1 (aOR: 1.97, 95% CI: 1.24-3.13), and higher BMI (aOR: 1.08, 95% CI: 1.05-1.11). A novel risk calculator for GDM in PG2 was developed based on these associations. Using a risk cut-off of 15%, the calculator had a positive predictive value of 26% and a negative predictive value of 97%, with 3.2% of patients identified as "at risk". Among patients with abnormal 1-hour GCT in PG1, 38.3% (n = 214/559) had an abnormal 1-hour GCT in PG2 and 34.5% (n = 74/214) of these patients received a diagnosis of GDM. CONCLUSION: A normal 1-hour GCT in an PG1 is followed by GDM in a subsequent pregnancy in only 3.9% of cases. A novel calculator supports replacing universal screening with targeted testing in subsequent pregnancies in this population. Among patients with an abnormal 1-hour GCT in PG1, nearly 40% have an abnormal 1-hour GCT in a subsequent pregnancy. Direct diagnostic testing can be considered in such patients. KEY POINTS: · Normal GCT in a first pregnancy is associated with normal GCT in subsequent pregnancy.. · A risk calculator can target diabetes testing in a subsequent pregnancy.. · Abnormal GCT in a first pregnancy is associated with abnormal GCT in subsequent pregnancy..

OBJECTIVE: The aim of this study was to evaluate whether the risk of perinatal depression is associated with body mass index (BMI) category. STUDY DESIGN: We performed a retrospective cohort study of women who completed an Edinburgh Postnatal Depression Scale (EPDS) questionnaire during the antepartum period at an integrated health system from January 2003 to May 2018. Risk of perinatal depression was defined as a score of ≥10 on the EPDS or an affirmative response to thoughts of self-harm. Risk of perinatal depression was compared by first trimester BMI category, defined as underweight (BMI: <18.5 kg/m2), normal weight (BMI: 18.5-24.9 kg/m2), overweight (BMI: 25.0-29.9 kg/m2), or obese (BMI: ≥30.0 kg/m2). Univariable analyses were performed using χ 2, Fisher's exact test, analysis of variance, Kruskal-Wallis, and Wilcoxon rank-sum tests as appropriate to evaluate the association between maternal BMI category, demographic and clinical characteristics, and risk of perinatal depression. Logistic multivariable regression models were performed to adjust for potential confounders identified as variables with p < 0.10 in univariable analysis. RESULTS: Our analysis included 3,420 obese women, 3,839 overweight women, 5,949 normal weight women, and 1,203 underweight women. The overall median gestational age at EPDS administration was 27 weeks (interquartile range: 23-29). Overweight and obese women were more likely to be non-Hispanic Black, Hispanic, multiparous, to have public insurance, prepregnancy diabetes, and chronic hypertension as compared with normal or underweight women (p < 0.001). In univariable analysis, the risk of perinatal depression was not significantly different among underweight (10.8%, odds ratio [OR]: 0.86, 95% confidence interval [CI]: 0.79-1.18) or overweight women (12%, OR: 0.96, 95% CI: 0.79-1.18); however, the risk was higher among obese women (14.7%, 95% CI: 1.21-1.55) compared with normal weight women (11.2%). In multivariable analysis, obesity remained associated with an increased risk of perinatal depression (adjusted OR: 1.19, 95% CI: 1.04-1.35). CONCLUSION: Obesity is associated with an increased risk of perinatal depression as compared with women of normal weight. KEY POINTS: · Maternal obesity is associated with an increased risk of perinatal depression.. · Maternal BMI is associated with increased risk of perinatal depression.. · Maternal obesity is an independent risk factor for perinatal depression..

OBJECTIVE: The objective of the study was to evaluate whether patients with oxytocin discontinued during the second stage of labor (≥30 minutes prior to delivery) had a lower rate of postpartum hemorrhage (PPH) compared with those with oxytocin continued until delivery or discontinued <30 minutes prior to delivery. STUDY DESIGN: Retrospective cohort study was performed from August 1, 2014 to July 31, 2019. Singleton pregnancies of 24 to 42 weeks gestation were included if they reached the second stage of labor and received oxytocin during labor. Patients on anticoagulants were excluded. Patients with oxytocin discontinued ≥30 minutes prior to delivery represented STOPPED and those with oxytocin continued until delivery or discontinued <30 minutes prior to delivery represented CONTINUED. Patient data were abstracted from the electronic medical record. The primary outcome was PPH (≥1,000 mL blood loss). Univariable analyses were performed to compare groups. Multi-variable logistic regression was performed to adjust for prespecified confounders. Planned sub-group analyses by the route of delivery were performed. RESULTS: Of 10,421 total patients, 1,288 had oxytocin STOPPED and 9,133 had oxytocin CONTINUED. There were no significant differences in age, race, or ethnicity, body mass index, public insurance, gestational diabetes, or pregnancy-induced hypertension between STOPPED and CONTINUED. The PPH rate was 15.2 and 5.7% in STOPPED and CONTINUED, respectively (p < 0.001). After adjusting for confounders, STOPPED remained at higher odds for PPH (adjusted odds ratio 2.859, 95% confidence interval 2.394, 3.414, p < 0.001). Among cesarean deliveries only, there was no significant difference in the rate of PPH between STOPPED and CONTINUED (38.0 vs. 36.4%, respectively, p = 0.730). However, among vaginal deliveries, the rate of PPH was actually lower in STOPPED than CONTINUED (3.4 vs. 5.2%, respectively, p = 0.024). CONCLUSION: The rate of PPH was higher in patients with oxytocin STOPPED compared with CONTINUED. However, among vaginal deliveries, there was a significantly lower rate of PPH in STOPPED. These disparate findings may be explained by the variable impact of second-stage oxytocin on PPH as a function of delivery type. KEY POINTS: · It is unclear if oxytocin use in the second stage of labor may independently increase the risk of hemorrhage.. · Patients with oxytocin discontinued during the second stage of labor had a higher rate of PPH.. · PPH was significantly lower among vaginal deliveries in patients with oxytocin discontinued..
RESUMO
OBJECTIVE: The aim of this study was to evaluate whether a 1-hour glucose challenge test (GCT) ≥140 mg/dL in a nondiabetic index pregnancy is associated with the development of gestational diabetes mellitus (GDM) in a subsequent pregnancy. STUDY DESIGN: We performed a retrospective cohort study from a single institution from June 2009 to December 2018. Women with a nondiabetic index singleton gestation who underwent a 1-hour GCT at 24 to 28 weeks and had a successive singleton delivery were included. GDM was defined by a 1-hour GCT of ≥ 200 mg/dL, ≥2 of 4 elevated values on a 3-hour GCT, or a diagnosis of GDM defined by International Classification of Disease codes in the electronic medical record. Univariable analyses were performed to evaluate the associations between an elevated 1-hour GCT result in the index pregnancy, maternal characteristics, and the development of GDM in the subsequent pregnancy. Variables found to be significant (p < 0.05) were included in multivariable analysis. RESULTS: A total of 2,423 women were included. Of these, 340 (14.0%) had an elevated 1-hour GCT in the index pregnancy. Women with an elevated 1-hour GCT in the index pregnancy compared with those without were significantly more likely to be older, married, privately insured, of Hispanic ethnicity or Asian race, chronically hypertensive, have a higher body mass index (BMI), have a shorter inter-pregnancy interval, and to develop GDM in the subsequent pregnancy (14.4 vs. 3.3%, p < 0.001). In multivariable analysis, an elevated 1-hour GCT (adjusted odds ratio [aOR]: 4.54, 95% confidence interval [CI]: 3.02-6.81), first-trimester BMI ≥30 kg/m2 in the index pregnancy (aOR: 3.10, 95% CI: 2.03-4.71), Asian race (aOR: 2.96, 95% CI: 1.70-5.12), Hispanic ethnicity (aOR: 2.11, 95% CI: 1.12-4.00), and increasing age (aOR: 1.07, 95% CI: 1.02-1.12) were significantly associated with an increased risk of GDM in the subsequent pregnancy. CONCLUSION: An elevated 1-hour GCT in a nondiabetic index pregnancy is associated with a fourfold increased risk of GDM in a subsequent pregnancy. KEY POINTS: · An abnormal 1 hour GCT in an index pregnancy is associated with GDM in a subsequent pregnancy.. · An abnormal 1 hour GCT may be an independent risk factor for GDM in a subsequent pregnancy.. · An abnormal 1 hour GCT is associated with a 4 fold increased risk of GDM in a subsequent pregnancy..

OBJECTIVE: Surgical site infections (SSI, including wound infections, endometritis, pelvic abscess, and sepsis) may complicate cesarean section (C/S). We report outcomes before and after the introduction of an SSI prevention bundle that did not include antibiotics beyond routine prophylaxis (cefazolin, or gentamicin/clindamycin for penicillin-allergic patients). STUDY DESIGN: The prevention bundle was introduced following an increase in C/S-associated SSI, which itself was associated with an institutional switch in preoperative scrub from povidone-iodine to chlorhexidine gluconate (CHG)/isopropanol. Components of the bundle included: (1) full-body preoperative wash with 4% CHG cloths; (2) retraining on surgeon hand scrub; (3) retraining for surgical prep; and (4) patient education regarding wound care. Patients delivered by C/S at ≥24 weeks of gestation were segregated into four epochs over 7 years: (1) baseline (18 months when povidone-iodine was used); (2) CHG scrub (18 months after skin prep was switched to CHG); (3) bundle implementation (24 months); and (4) maintenance (24 months following implementation). RESULTS: A total of 3,637 patients were included (n = 667, 796, 1098, and 1076, respectively, in epochs 1-4). A rise in SSI occurred with the institutional switch from povidone-iodine to CHG (i.e., from baseline to the CHG scrub epoch, 8.4-13.3%, p < 0.01). Following the intervention (maintenance epoch), this rate decreased to below baseline values (to 4.5%, p < 0.01), attributable to a decline in wound infection (rates in the above three epochs 6.9, 12.9, and 3.5%, respectively, p < 0.01), with no change in endometritis. In multivariable analysis, only epoch and body mass index (BMI) were independently associated with SSI. The improvement associated with the prevention bundle held for stratified analysis of specific risk factors such as chorioamnionitis, prior C/S, obesity, labor induction, and diabetes. CONCLUSION: Implementation of a prevention bundle was associated with a reduction in post-C/S SSI. This improvement was achieved without the use of antibiotics beyond standard preoperative dosing.

Screens and adjunctive treatments for perinatal mood are available, but barriers prevent many women from receiving them. Mobile technology may help bypass barriers. The purpose of this study was to evaluate the feasibility of screening and texting perinatal women via their personal smartphones. This prospective cohort study enrolled 203 pregnant and postpartum women receiving obstetric care at a Midwestern US academic medical center. Participants received one electronic mood screen and three text messages per week for two weeks. Texts were based on the Mothers and Babies Course, a CBT-based preventative program that addresses limited social support, lack of pleasant activities, and harmful thought patterns. Feasibility was defined as the ability to take the mood screen and receive texts without technical difficulties. Demographic variables were paired with results. Insurance type (private or public) was used as a proxy for socioeconomic status. Pearson chi-squared tests were used to analyze the data. A text-based satisfaction survey was also administered. The sample was 72% privately insured and 28% publicly insured. Sixty-seven percent completed electronic screening. Screen completion was significantly associated with private insurance (OR = 3.8, 95% CI 2.00-7.30) and "married" status (OR = 1.93, 95% CI 1.01-3.70). Most survey respondents (92%) found it easy to receive the texts, and 76% responded with very favorable comments about the texts. Smartphone mood screening and supportive texting were technically feasible. Screen completion was lower among single women with public insurance.

We assessed differential item functioning (DIF) based on computerized adaptive testing (CAT) to examine how perinatal mood disorders differ from adult psychiatric disorders. The CAT-Mental Health (CAT-MH) was administered to 1614 adult psychiatric outpatients and 419 perinatal women with IRB approval. We examined individual item-level differences using logistic regression and overall score differences by scoring the perinatal data using the original bifactor model calibration based on the psychiatric sample data and a new bifactor model calibration based on the perinatal data and computing their correlation. To examine convergent validity, we computed correlations of the CAT-MH with contemporaneously administered Edinburgh Postnatal Depression Scales (EPDS). The rate of major depression in the perinatal sample was 13 %. Rates of anxiety, mania, and suicide risk were 5, 6, and 0.4 %, respectively. One of 66 depression items, one of 69 anxiety items, and 15 of 53 mania items exhibited DIF (i.e., failure to discriminate between high and low levels of the disorder) in the perinatal sample based on the psychiatric sample calibration. Removal of these items resulted in correlations of the original and perinatal calibrations of r = 0.983 for depression, r = 0.986 for anxiety, and r = 0.932 for mania. The 91.3 % of cases were concordantly categorized as either "at-risk" or "low-risk" between the EPDS and the perinatal calibration of the CAT-MH. There was little evidence of DIF for depression and anxiety symptoms in perinatal women. This was not true for mania. Now calibrated for perinatal women, the CAT-MH can be evaluated for longitudinal symptom monitoring.

To explore the potential of an integrated outpatient electronic health record (EHR) for preconception health optimization. An automated case-finding EHR-derived algorithm was designed to identify women of child-bearing age having outpatient encounters in an 85-site, integrated health system. The algorithm simultaneously cross-referenced multiple discrete data fields to identify selected preconception factors (obesity, hypertension, diabetes, teratogen use including ACE inhibitors, multivitamin supplementation, anemia, renal insufficiency, untreated sexually transmitted infection, HIV positivity, and tobacco, alcohol or illegal drug use). Surveys were mailed to a random sample of patients to obtain their self-reported health profiles for these same factors. Concordance was assessed between the algorithm output, survey results, and manual data abstraction. Between 8/2010-2/2012, 107,339 female outpatient visits were identified, from which 29,691 unique women were presumed to have child-bearing potential. 19,624 (66 %) and 8,652 (29 %) had 1 or ≥2 health factors, respectively while only 1,415 (5 %) had none. Using the patient survey results as a reference point, health-factor agreement was similar comparing the algorithm (85.8 %) and the chart abstraction (87.2 %) results. Incorrect or missing data entries in the EHR encounters were largely responsible for discordances observed. Preconception screening using an automated algorithm in a system-wide EHR identified a large group of women with potentially modifiable preconception health conditions. The issue most responsible for limiting algorithm performance was incomplete point of care documentation. Accurate data capture during patient encounters should be a focus for quality improvement, so that novel applications of system-wide data mining can be reliably implemented.

OBJECTIVE: We evaluated the relationship between antenatal depressive symptoms and preterm birth. STUDY DESIGN: Patients completed the Edinburgh Postnatal Depression Scale between 24-28 weeks of gestation. A score ≥ 12 (or thoughts of self-harm) indicated an at-risk woman. Symptomatic women were compared to risk-negative patients for relevant demography, historical variables, and pregnancy outcome. RESULTS: After screening 14,175 women we found a screen positive rate of 9.1% (n = 1298). At-risk women had a significant increase in preterm birth at <37, <34, <32, and <28 weeks of gestation. Multivariable analysis adjusting for maternal age, race/ethnicity, prior preterm delivery, and insurance status revealed a persistent association between antenatal depressive symptoms and preterm birth (adjusted odds ratio, 1.3; 95% confidence interval, 1.09-1.35), which was also observed after multiple gestations were excluded from the analysis (odds ratio, 1.7; 95% confidence interval, 1.38-1.99). CONCLUSION: In this large cohort of prenatally screened women, those with depressive symptoms had an increased likelihood of preterm birth.

OBJECTIVE: Determine whether depression screen results are consistent across successive pregnancies. STUDY DESIGN: The Edinburgh Postnatal Depression Scale was administered in 2 successive pregnancies to 2116 women. A woman was "screen-positive" if she scored ≥ 12 at 24-28 weeks' or 6-weeks' postpartum. Screen-positive women were assessed by telephone and triaged by mental health professionals. RESULTS: Most women (87.9%) were screen-negative in both pregnancies; 1.7% screened successively positive, 5.9% screened positive in only the first pregnancy; 4.5% screened positive in only the second pregnancy. Unpartnered, nonwhite, and publicly insured women were each likelier to screen positive in either or both pregnancies (P < .0001). Gestational age at delivery was significantly greater in women who never screened positive (P < .05). A majority (63%) of screen-positive women in both pregnancies reported no history of mood disorder. CONCLUSION: There is sufficient variability in depression screening results between successive gestations to warrant screening during each pregnancy.

The aim of this study was to determine whether meteorological factors are associated with the timing of either onset of labor with intact membranes or rupture of membranes prior to labor-together referred to as 'the initiating event' of parturition. All patients delivering at Evanston Hospital after spontaneous labor or rupture of membranes at ≥20 weeks of gestation over a 6-month period were studied. Logistic regression models of the initiating event of parturition using clinical variables (maternal age, gestational age, parity, multiple gestation and intrauterine infection) with and without the addition of meteorological variables (barometric pressure, temperature and humidity) were compared. A total of 1,088 patients met the inclusion criteria. Gestational age, multiple gestation and chorioamnionitis were associated with timing of initiation of parturition (P < 0.01). The addition of meteorological to clinical variables generated a statistically significant improvement in prediction of the initiating event; however, the magnitude of this improvement was small (less than 2% difference in receiver-operating characteristic score). These observations held regardless of parity, fetal number and gestational age. Meteorological factors are associated with the timing of parturition, but the magnitude of this association is small.

To investigate obstetric care provider attitudes toward perinatal depression screening and factors associated with variable screening rates. Provider attitudes about depression screening were investigated via structured interviews (open-ended and rating scale questions) and analyzed using qualitative content analysis. Most providers (86%) found screening effective at identifying women at risk for perinatal depression (average rating of 8.7 on 10-point analog scale). However, 95% overestimated their own screening rates and 67% inaccurately thought they achieved universal screening. Providers not directly involved in their office-based screening process demonstrated lower average screening rates (37%) than those who maintained active involvement (59%; p = 0.07). Obstetric care providers support perinatal depression screening in the context of a program that assumes responsibility for processing screens, conducts assessments of at-risk women and provides referrals to mental health professionals. Provider participation in screening and tying screening to routine obstetric outpatient activities such as glucose tolerance testing are associated with higher screening rates.

OBJECTIVE: The purpose of this study was to estimate the prevalence of maternal depressive risk in patients during the third trimester and to determine whether unique at-risk women are identified when the data are compared with postpartum screening. STUDY DESIGN: As part of a comprehensive program for universal perinatal depression screening and behavioral health referral of at-risk women, patients completed the Edinburgh Postnatal Depression Scale both during pregnancy (24-28 weeks of gestation) and again at 6 weeks after delivery. Based on Edinburgh Postnatal Depression Scale scores of > or =12, the prevalence of antepartum depressive risk and the rates of concordant/discordant risk status with the corresponding postpartum results were calculated. Discordant-risk cases were further analyzed to determine whether obstetric, psychosocial, or demographic variables were associated with changing risk status over time. RESULTS: We screened 1584 women in the third trimester and again after delivery: 7.7% and 6.8% of the women scored in the at-risk range in the antepartum and postpartum time frames, respectively; 88.9% of patients had the same risk status, and 11.1% were discordant before and after delivery. Statistically significant associations were found between premature birth, newborn infant admission to the intensive care nursery, and acquisition of postpartum depressive risk. CONCLUSION: Screening for depression in the third trimester resulted in a comparable prevalence rate of depressive risk identification when compared with the postpartum time frame. Unique women were identified before and after delivery who may have been missed if screening had not been performed twice.

OBJECTIVE: Postpartum hemorrhage (PPH), a major cause of maternal mortality and morbidity in low-income countries, can occur unpredictably. This study examined the sociodemographic, clinical, and perinatal characteristics of low-risk women who experienced PPH. METHODS: This analysis was conducted using data on 1620 women from a randomized trial testing oral misoprostol for prevention of PPH in rural India. RESULTS: Of the women, 9.2% experienced PPH. No maternal or sociodemographic factors and few perinatal factors differed between women with PPH and those without, other than treatment with misoprostol. Having fewer than 4 prenatal visits and lack of iron supplementation increased the risk for PPH (P<0.001 and P=0.037, respectively). Several factors unknown until the second stage of labor (perineal tear and birth weight) were also associated (P=0.003). CONCLUSIONS: Among women at low risk for PPH, there were few factors associated with further risk. Given that PPH can occur without warning, rural communities should consider ways to increase both primary prevention (iron supplementation, AMTSL) and secondary prevention of PPH (availability of obstetric first aid, availability of transport, and availability of emergency obstetric care).

STUDY DESIGN: One hundred cases of serious morbidity and death among peripartum women were reviewed by 2 independent groups of medical experts to identify potentially preventable provider or system events that may have led to the progression of illness. RESULTS: Seventy-seven percent of the cases had concordant findings in both groups regarding the identification of any preventable events. Interrater agreement, which was measured by Cohen's Kappa, was 0.49, which suggests moderate to good reliability. Cases with multiple comorbidities, poor documentation, or preventable patient factors tended to have higher levels of disagreement. CONCLUSION: There was high agreement between the 2 groups regarding the identification of preventable events that impact maternal morbidity and death. The reliability of this model for the assessment of preventability is an important step for improvement in obstetric and medical care.

The leading cause of maternal mortality is hemorrhage, generally occurring in the postpartum period. Current levels of PPH-related morbidity and mortality in low-resource settings result from institutional, environmental, cultural and social barriers to providing skilled care and preventing, diagnosing and treating PPH. Conventional uterotonics to prevent PPH are typically not available or practical for use in low-resource settings. In such deliveries, most often taking place at home or in rural health centers, underestimation of blood loss leads to a delay in diagnosis. Deficiencies in communication and transportation infrastructure impede transfer to a higher level of care. Inability to stabilize a patient who is in hemorrhagic shock rapidly results in death. To address these individual factors, we propose a continuum of care model for PPH, including routine use of prophylactic misoprostol or other appropriate uterotonic, a standardized means of blood loss assessment, availability of a non-pneumatic anti-shock garment, and systemization of communication, transportation, and referral. Such a multifaceted, systematic, contextualized PPH continuum of care approach may have the greatest impact for saving women's lives. This model should be developed and tested to be region-specific.

BACKGROUND: The National Institutes of Health Revitalization Act of 1993 requires that NIH-funded clinical trials include women and minorities as subjects; other federal agencies have adopted similar guidelines. The objective of this study was to determine the current level of compliance with these guidelines in federally funded randomized controlled trials. METHODS: Randomized controlled trials published in nine influential medical journals in 2004 were identified by PubMed search. Studies where individuals were not the unit of analysis, those begun before 1994, and those not receiving federal funding were excluded. Included studies were examined to determine sample characteristics and presence of subgroup reporting. RESULTS: PubMed located 589 published papers. After exclusion of ineligible papers, 69 remained for analysis. Among 46 clinical studies enrolling both men and women, women were generally underrepresented, comprising on average 37% of the sample and only 24% of the sample when analysis was restricted to drug trials. Eighty-seven percent of the studies did not report any outcomes by sex or include sex as a covariate in modeling. Among all 69 studies, 18% did not break down sample sizes by racial and ethnic groups, and 87% did not provide any analysis by racial or ethnic groups. Only 5 studies indicated that the generalizability of their results may be limited by lack of diversity among those studied. CONCLUSIONS: These findings illustrate inadequate compliance with the NIH guidelines. Researchers, editors, and journal audiences share the responsibility of ensuring compliance with our country's policies regarding federally funded research to effect healthcare improvements for all.

OBJECTIVE: To estimate the incidence and clinical significance of suicidal ideation revealed during perinatal depression screening and estimate the associated suicide risk. METHODS: Retrospective cohort study of women completing the Edinburgh Postnatal Depression Scale at 24-28 weeks of gestation and 6 weeks postpartum through a suburban integrated health system with approximately 5,000 annual deliveries on two hospital campuses. Suicidal ideation on the Edinburgh Postnatal Depression Scale and prediction of suicide risk were examined through multivariable modeling and qualitative analysis of clinical assessments. RESULTS: Among 22,118 Edinburgh Postnatal Depression Scale questionnaires studied, suicidal ideation was reported on 842 (3.8%, 95% confidence interval [CI] 3.5-4.1%) and was positively associated with younger maternal age (antepartum mean age 30.9 compared with 31.9 years, P=.001), unpartnered relationship status (antepartum 29.5% compared with 16.5%, P<.001 and postpartum 25.0% compared with 17.5%, P<.01), non-Caucasian race (antepartum 62.1% compared with 43.8%, P<.001 and postpartum 62.4% compared with 45.2%, P<.001), non-English language (antepartum 11.0% compared with 6.6%, P<.001 and postpartum 12.4% compared with 7.7%, P<.01), public insurance (antepartum 19.9% compared with 12.5%, P<.001 and postpartum 18.2% compared with 14.2%, P<.001), and preexisting psychiatric diagnosis (antepartum 8.4% compared with 4.2%, P<.001 and postpartum 12.0% compared with 5.8%, P<.001). Multivariable antepartum and postpartum models retained relationship status, language, relationship status by language interaction, and race; the postpartum model also found planned cesarean delivery negatively associated with suicidal ideation risk (odds ratio [OR] 0.56, 95% CI 0.36-0.87) and severe vaginal laceration positively associated with suicidal ideation risk (OR 2.1, 95% CI 1.00-4.40). A qualitative study of 574 women reporting suicidal ideation indicated that 330 (57.5%, 95% CI 53.5-61.5%) experienced some degree of suicidal thought. Six patients (1.1%, 95% CI 0.2-1.9%) demonstrated active suicidal ideation with plan, intent, and access to means. Within this highest risk group, three patients reported a suicide attempt within the perinatal period. CONCLUSION: Among perinatal women screened for depression, 3.8% reported suicidal ideation, but only 1.1% of this subgroup was at high risk for suicide. These findings support the need for systematic evaluation of those who report suicidal ideation to identify the small subset requiring urgent evaluation and care.

Objective This study aims to determine if shoulder dystocia is associated with a difference in the fetal abdominal (AC) to head circumference (HC) of 50 mm or more noted on antenatal ultrasound. Study Design A multicenter matched case-control study was performed comparing women who had shoulder dystocia to controls who did not. Women with vaginal births of live born nonanomalous singletons ≥ 36 weeks of gestation with an antenatal ultrasound within 4 weeks of delivery were included. Controls were matched for gestational age, route of delivery, and diabetes status. Results We identified 181 matched pairs. Only 5% of the fetuses had an AC to HC of ≥ 50 mm. The proportion of AC to HC difference of ≥ 50 mm was significantly higher in shoulder dystocia cases (8%) than controls (1%, p = 0.002). With multivariate regression, the three significant factors associated with shoulder dystocia were AC to HC ≥ 50 mm (odds ratio [OR], 7.3; confidence interval [CI], 1.6-33.3; p = 0.010), femur length (OR, 1.1; CI, 1.0-1.2; p = 0.002), and induced labor (OR, 1.8; CI, 1.1-3.1; p = 0.027). Conclusion A prenatal ultrasound finding of a difference in AC to HC of ≥ 50 mm while uncommon is associated with shoulder dystocia.
