Association Between Maternal Depression and Lower Urinary Tract Symptoms in Their Primary School-Age Daughters: A Birth Cohort Study

PURPOSE

Although maternal depression is associated with adverse outcomes in women and children, its relationship with lower urinary tract symptoms (LUTS) in offspring is less well-characterized. We examined the association between prenatal and postpartum maternal depression and LUTS in primary school-age daughters.

DESIGN

Observational cohort study.

SUBJECTS AND SETTING

The sample comprised 7148 mother-daughter dyads from the Avon Longitudinal Study of Parents and Children.

METHOD

Mothers completed questionnaires about depressive symptoms at 18 and 32 weeks' gestation and 21 months postpartum and their children's LUTS (urinary urgency, nocturia, and daytime and nighttime wetting) at 6, 7, and 9 years of age. Multivariable logistic regression models were used to estimate the association between maternal depression and LUTS in daughters.

RESULTS

Compared to daughters of mothers without depression, those born to mothers with prenatal and postpartum depression had higher odds of LUTS, including urinary urgency (adjusted odds ratio [aOR] range = 1.99-2.50) and nocturia (aOR range = 1.67-1.97) at 6, 7, and 9 years of age. Additionally, daughters born to mothers with prenatal and postpartum depression had higher odds of daytime wetting (aOR range = 1.81-1.99) and nighttime wetting (aOR range = 1.63-1.95) at 6 and 7 years of age. Less consistent associations were observed for depression limited to the prenatal or postpartum periods only.

CONCLUSIONS

Exposure to maternal depression in the prenatal and postpartum periods was associated with an increased likelihood of LUTS in daughters. This association may be an important opportunity for childhood LUTS prevention. Prevention strategies should reflect an understanding of potential biological and environmental mechanisms through which maternal depression may influence childhood LUTS.

Occupational groups and lower urinary tract symptoms: A cross-sectional analysis of women in the Boston Area Community Health Study

OBJECTIVES

The objective of this study is to inform our hypothesis that the workplace toileting environment may impact lower urinary tract symptoms (LUTS); we examined the prevalence of LUTS across occupational groups in the Boston Area Community Health Survey.

METHODS

At baseline, women (n = 3205) reported their occupation and frequency of 15 LUTS. Using the US Department of Labor's Standard Occupational Classification (SOC) system, we categorized women into 11 standard occupational groups. Prevalence ratios (PRs) were calculated by log-link generalized linear models, adjusting for age, race, education, fluid intake, and parity. Women classified in Office and Administrative Support were used as the reference group given their potential for fewer workplace toileting restrictions.

RESULTS

Of the 3189 women with complete data, 68% of women reported any LUTS, ranging from 57% to 82% across the SOCs. Relative to women in Office and Administrative Support (n = 576), women in Computing, Engineering, and Science (n = 64) were more likely to report any LUTS (PR = 1.2, 95% confidence interval [95% CI]: 1.0-1.4) and urinating again in <2 h (PR = 1.7, 95% CI: 1.4-2.2), and women in Education, Legal, Community Service, Arts, and Media (n = 477), as well as Healthcare Practitioner and Technical Occupations (n = 162), were less likely to report perceived frequent daytime urination (PR = 0.6, 95% CI: 0.5-0.9 and PR = 0.6, 95% CI: 0.4-0.9, respectively).

CONCLUSIONS

Our cross-sectional findings suggest that urination frequency varies across understudied occupational groups with various workplace toileting environments. Future studies should examine this relationship prospectively to inform the influence of workplace toileting environments on urination frequency, as well as the development and/or worsening of LUTS.

Sexual Health Behaviors by Age 17 and Lower Urinary Tract Symptoms at Age 19: PLUS Research Consortium Analysis of ALSPAC Data

PURPOSE

We examined how antecedent sexual health factors affect lower urinary tract symptoms (LUTS) in adolescent women.

METHODS

We analyzed 1,941 adolescent women from the Avon Longitudinal Study of Parents and Children at age 19. At ages 15 and 17, participants reported use of oral contraceptives (OCs), history of sexual intercourse, number of sexual partners, and condom use. At age 19, The Bristol Female Lower Urinary Tract Symptoms questionnaire quantified the frequency over the past month: stress incontinence, any incontinence, urgency, sensation of incomplete emptying, bladder pain, and urinary tract infection. Multivariable regression models examined associations between sexual health behaviors reported at ages 15 and 17 and six LUTS reported at age 19, after controlling for covariates.

RESULTS

Commonly reported LUTS at age 19 were past-month stress incontinence (26.8%), bladder pain (26.3%), any urine leakage (22.1%), and urinary tract infection (15.4%). OC use by age 17 was associated with urgency (odds ratio [OR] = 1.62, 95% confidence interval [CI] 1.19-2.20), incomplete emptying (OR = 1.62, 95% CI = 1.17-2.26), bladder pain (OR = 1.45, 95% CI = 1.15-1.83), and urinary tract infections (OR = 1.68, 95% CI = 1.28-2.21) at age 19 after adjustment for covariates. However, associations were attenuated after adjustment for condom use and number of sexual partners. Sexual intercourse by age 17 was associated with 1.53-2.65 increased odds of LUTs categories except incontinence, with lower confidence interval boundaries > 1.0. Associations were stronger among women with ≥ 3 sexual partners (vs. 0) by age 17.

DISCUSSION

We found longitudinally assessed associations between OC use, sexual intercourse, and number of sexual partners during adolescence and LUTS at age 19.

Associations Between Preconception Glycemia and Preterm Birth: The Potential Role of Health Care Access and Utilization

Background: Preconception diabetes is strongly associated with adverse birth outcomes. Less is known about the effects of elevated glycemia at levels below clinical cutoffs for diabetes. In this study, we estimated associations between preconception diabetes, prediabetes, and hemoglobin A1c (HbA1c) on the risk of preterm birth, and evaluated whether associations were modified by access to or utilization of health care services. Materials and Methods: We used data from Add Health, a US prospective cohort study with five study waves to date. At Wave IV (ages 24-32), glucose and HbA1c were measured. At Wave V (ages 32-42), women with a live birth reported whether the baby was born preterm. The analytic sample size was 1989. Results: The prevalence of preterm birth was 13%. Before pregnancy, 6.9% of women had diabetes, 23.7% had prediabetes, and 69.4% were normoglycemic. Compared to the normoglycemic group, women with diabetes had 2.1 (confidence interval [95% CI]: 1.5-2.9) times the risk of preterm birth, while women with prediabetes had 1.3 (95% CI: 1.0, 1.7) times the risk of preterm birth. There was a nonlinear relationship between HbA1c and preterm birth such that risk of preterm birth emerged after HbA1c = 5.7%, a standard cutoff for prediabetes. The excess risks of preterm birth associated with elevated HbA1c were four to five times larger among women who reported unstable health care coverage and among women who used the emergency room as usual source of care. Conclusion: Our findings replicate prior research showing strong associations between preconception diabetes and preterm birth, adding that prediabetes is also associated with higher risk. Policies and interventions to enhance access and utilization of health care among women before pregnancy should be examined.

Non-invasive bladder function measures in healthy, asymptomatic female children and adolescents: A systematic review and meta-analysis

BACKGROUND

Lower urinary tract symptoms (LUTS) are common in children and adolescents. Non-invasive tests evaluating bladder function are generally preferred over invasive tests, yet few studies have explored the range of normative values for these tests in healthy, asymptomatic children.

OBJECTIVE

To define normative reference ranges for non-invasive tests of bladder function in healthy, asymptomatic girls and adolescents.

STUDY DESIGN

A comprehensive search strategy was performed in seven electronic databases through October 2019. English-language studies reporting data on voiding frequency, voided and postvoid residual volumes (PVR) and uroflowmetry results in healthy, asymptomatic girls (mean age ≥ 5 years) were included. Two independent reviewers performed study review, data extraction, and quality assessment. Overall mean estimates and 95% confidence intervals for each bladder function parameter were calculated using random effects models, and 95% normative reference values were estimated.

RESULTS

Ten studies met eligibility criteria for the meta-analysis (n = 2143 girls, age range: 3-18). Mean estimates of maximum voided volume and PVR were 233.4 ml (95% CI 204.3-262.6; n = 1 study) and 8.6 ml (95% CI 4.8-12.4; n = 2 studies) respectively. Pooled mean estimates for uroflowmetry parameters were: 21.5 ml/s (95% CI 20.5-2.5) for maximum flow rate (n = 6 studies), 12.5 ml/s (95% CI 11.2-13.8) for mean flow rate (n = 6 studies), 6.8 s (95% CI 4.4-9.3) for time to maximum flow (n = 3 studies), 15.7 s (95% CI 13.0-18.5) for flow time (n = 3 studies), and 198.7 ml (95% CI 154.2-234.2) for voided volume (n = 9 studies). No studies reported estimates of voiding frequency. Between-study heterogeneity was high (89.0-99.6%).

CONCLUSIONS

Although we were able to calculate pooled mean estimates for several parameters, the small number of included studies and the wide age ranges of participants preclude generalization of reference values to all healthy girls. Further research is needed to determine normative reference values within specific age groups.

Views of Normal Bladder Function Among Women Experiencing Lower Urinary Tract Symptoms

OBJECTIVE

To explore the perspectives of normal bladder function among women with lower urinary tract symptoms.

METHODS

This was a secondary analysis of qualitative data from structured interviews with 50 adult women with lower urinary tract symptoms. A directed content analysis of the transcripts explored women's perspectives on normal bladder function.

RESULTS

Participants' descriptions of "normal" took many forms and were based on several aspects of bladder function. A prominent feature of normal was that voiding occurred as a seamless process, beginning with an urge sensation, followed by voiding with ease and to completion, and then "being done." Descriptions of normal were based largely on concepts of voiding regularity, including voiding frequency, intervals, and patterns during the day and night. Another aspect of normal bladder function was the notion of having control in terms of not leaking urine, as well as the ability to hold urine and defer urination. Views of normal bladder function extended to the absence of symptoms and the impact of being symptom-free on day-to-day life, including not having to think about or worry about the bladder or limit daily activities.

CONCLUSION

Women's perspectives on normal bladder function are multifaceted, reflecting attributes most salient to each individual and likely informed by their personal experience with symptoms and their influence on daily life. This work has implications for how clinicians might engage women in discussing bladder symptoms and can inform future research and public health messaging about normal bladder function.

Applying concepts of life course theory and life course epidemiology to the study of bladder health and lower urinary tract symptoms among girls and women

AIMS

Although lower urinary tract symptoms (LUTS) may occur at different periods during the life course of women, a little research on LUTS has adopted a life course perspective. The purpose of this conceptual paper is to demonstrate how life course theory and life course epidemiology can be applied to study bladder health and LUTS trajectories. We highlight conceptual work from the Prevention of Lower Urinary Tract Symptoms Research Consortium to enhance the understanding of life course concepts.

METHODS

Consortium members worked in transdisciplinary teams to generate examples of how life course concepts may be applied to research on bladder health and LUTS in eight prioritized areas: (a) biopsychosocial ecology of stress and brain health; (b) toileting environment, access, habits, and techniques; (c) pregnancy and childbirth; (d) physical health and medical conditions; (e) musculoskeletal health; (f) lifestyle behaviors; (g) infections and microbiome; and (h) hormonal status across the life span.

RESULTS

Life course concepts guided consortium members' conceptualization of how potential risk and protective factors may influence women's health. For example, intrapartum interventions across multiple pregnancies may influence trajectories of bladder health and LUTS, illustrating the principle of life span development. Consortium members also identified and summarized methodologic and practical considerations in designing life course research.

CONCLUSIONS

This paper may assist researchers from a variety of disciplines to design and implement research identifying key risk and protective factors for LUTS and bladder health across the life course of women. Results from life course research may inform health promotion programs, policies, and practices.

Normative noninvasive bladder function measurements in healthy women: A systematic review and meta-analysis

AIM

To conduct an evidence synthesis of normative reference values for bladder function parameters in women.

METHODS

We conducted a systematic review and meta-analysis of studies reporting bladder function parameters obtained from noninvasive tests in healthy women. Seven databases were searched for relevant studies from inception through December 2018, with manual searching of reference lists. We included English language articles that provided quantitative data on urination frequency, voided and postvoid residual volumes, and uroflowmetry results in women without lower urinary tract symptoms. Study selection, data extraction, and quality assessment were undertaken by at least two independent reviewers. Random-effects meta-analytic models were used to derive study-level pooled mean estimates and 95% confidence intervals.

RESULTS

A total of 24 studies (N = 3090 women, age range, 18-91 years) met eligibility criteria. Pooled mean estimates of bladder function parameters were: 6.6 daytime voids (95% confidence interval (95% CI), 6.2, 7.0), 0.4 nighttime voids (95% CI, 0.0, 0.8), 1577 mL for 24-hour voided volume (95% CI 1428,1725); 12 mL for postvoid residual volume (95% CI, 4, 20); and 28 mL/sec for maximum flow rate (95% CI, 27,30). Between-study heterogeneity was high for all outcomes (I²  = 61.1-99.6%), but insufficient data were available to explore reasons for this high heterogeneity (eg, differences by age).

CONCLUSION

Although summary mean estimates of bladder function parameters were calculated, the wide heterogeneity across studies precludes generalization of these estimates to all healthy women. Further research is needed to determine normative reference values within specific groups, such as those defined by age.

Early Second Trimester Weight Gain in Obese Women Predicts Excessive Gestational Weight Gain in Pregnancy

OBJECTIVE

To assess gestational weight gain (GWG) in obese women to determine an inflection point that identifies women at risk for excessive weight gain.

STUDY DESIGN

This is an observational prospective cohort study of pregnancies managed through the UC San Diego Maternal Weight and Wellness Program from 2011 to 2014. The primary outcome was total gestational weight gain. GWG was categorized as inadequate (<11 pounds), adequate (11-20 pounds), and excessive (>20 pounds) based on Institute of Medicine (IOM) recommendations. Other outcomes were GWG by trimester and postpartum weight retention. Bivariate and multivariate analyses were used to assess factors associated with GWG.

RESULTS

Ninety-five patients had a mean prepregnancy body mass index (BMI) of 41.9 ± 8.9 kg/m(2) and a net weight gain of 21.9 ± 19 pounds. First trimester GWG was -0.3 ± 4.9 pounds, second trimester was 10.4 ± 10.8 pounds, and third trimester was 11.4 ± 8.5 pounds for all participants. Women who exceeded IOM recommendations accelerated weight gain at 12-14 weeks and gained a majority of weight during the second trimester. Weight gain of more than two pounds at 12-14 weeks had a 96 % positive predictive value (95 % CI 79-99) for excessive GWG. Postpartum women with excessive GWG retained more weight than those with inadequate GWG (10.7 ± 15.6 pounds compared with -13.6 ± 10.9 pounds, P < 0.001). On multiple linear regression GWG by trimester was predictive of total GWG with second and third trimester GWG having the greatest effect on total GWG. Prepregnancy BMI and gestational diabetes were not predictors of total GWG.

CONCLUSIONS

Obese women at risk for excessive GWG may be identified as early as 12-14 weeks and gain most weight during the second trimester. GWG less than 11 pounds resulted in significant postpartum weight loss among obese women.

Maternal obesity and sex-specific differences in placental pathology

OBJECTIVE

Adverse effects of obesity have been linked to inflammation in various tissues, but studies on placental inflammation and obesity have demonstrated conflicting findings. We sought to investigate the influence of pregravid obesity and fetal sex on placental histopathology while controlling for diabetes and hypertension.

METHODS

Placental histopathology focusing on inflammatory markers of a cohort of normal weight (BMI = 20-24.9) and obese (BMI ≥ 30) patients was characterized. Demographic, obstetric and neonatal variables were assessed.

RESULTS

192 normal and 231 obese women were included. Placental characteristics associated with obesity and fetal sex independent of diabetes and hypertension were placental disc weight >90(th) percentile, decreased placental efficiency, chronic villitis (CV), fetal thrombosis, and normoblastemia. Additionally, female fetuses of obese mothers had higher rates of CV and fetal thrombosis. Increasing BMI increased the risk of normoblastemia and CV. The final grade and extent of CV was significantly associated with obesity and BMI, but not fetal gender. Finally, CV was less common in large-for-gestation placentas.

CONCLUSIONS

Maternal obesity results in placental overgrowth and fetal hypoxia as manifested by normoblastemia; it is also associated with an increased incidence of CV and fetal thrombosis, both more prevalent in female placentas. We have shown for the first time that the effect of maternal obesity on placental inflammation is independent of diabetes and hypertension, but significantly affected by fetal sex. Our data also point to the intriguing possibility that CV serves to normalize placental size, and potentially fetal growth, in the setting of maternal obesity.

Postpartum depression: risks, protective factors, and the couple's relationship

This study examined pregnancy risk for developing, and protective factors for preventing, Postpartum Depression (PPD). The object of this study was to (a) examine previously identified pregnancy stressors to learn which stressors put women more at risk for PPD and (b) to identify possible buffers for women who are at risk for developing PPD. A secondary data set was used for two analyses. Women were invited to participate in the study while still in the hospital, within 24-48 hours after delivery of a singleton, term (≥37 weeks) live-born infant. The data were collected in four large urban hospitals in Utah from 2005-2007. A total of 1,568 women participated in the study. Women who report experiencing less stress in their couple relationship are less likely to report PPD symptoms even when they have a personal history of depression and or PPD. The results of these analyses illustrate that a couple's relationship, depending on the stress level experienced in the relationship, can be both a risk and protective factor for pregnant women.

Abnormal second-trimester serum analytes are more predictive of preterm preeclampsia

OBJECTIVE

We sought to determine the association of abnormal second-trimester serum analytes with early preterm preeclampsia.

STUDY DESIGN

We conducted a retrospective study of 7767 subjects undergoing second-trimester serum aneuploidy screening. Values of maternal serum α-fetoprotein (AFP), β-human chorionic gonadotropin (hCG), and inhibin (INH) were calculated as multiples of the median (MoM) and evaluated by gestational age at delivery and occurrence of preeclampsia.

RESULTS

Of 459 (6.5%) cases of preeclampsia, 65 (14%) delivered <34 weeks and 394 (86%) delivered >34 weeks. Elevated AFP, hCG, and INH >2 MoM were associated with preeclampsia, and the odds ratio was higher for the development of preeclampsia <34 weeks than >34 weeks (odds ratio, 8.04 vs 2.91 for AFP, 3.6 vs 2 for hCG, and 4.17 vs 3.08 for INH, P < .001 for all). The higher the MoM for each analyte the greater the likelihood of preeclampsia.

CONCLUSION

Elevated AFP, hCG, and INH levels >2 MoM are associated with developing early preeclampsia, and the more elevated they are, the higher the likelihood.

The association between prepregnancy obesity and screening positive for postpartum depression

OBJECTIVE

To describe the association between reported prepregnancy body mass index (BMI) and screening positive for depression.

DESIGN

Cohort study.

SETTING

Four urban hospitals in Utah, USA.

POPULATION

Women delivering a term, singleton, live-born infant at one of four urban hospitals in Utah in the period 2005-2007.

METHODS

Women were enrolled immediately postpartum. Demographic, anthropometric, stressors, psychiatric, and medical/obstetric and family-history data were obtained. Prepregnancy height, weight, and pregnancy weight gain were self-reported. The primary exposure variable, prepregnancy BMI, was calculated. Women were stratified into the six World Health Organization BMI categories (underweight, normal weight, pre-obese, or obese class 1-3).

MAIN OUTCOME MEASURE

At 6-8 weeks postpartum, women were screened for depression using the Edinburgh Postnatal Depression Scale (EPDS). The primary outcome measure was a prespecified EPDS score of > or =12.

RESULTS

Among the 1053 women studied, 14.4% of normal weight women screened positive for postpartum depression. This proportion was greater in women classed as underweight (18.0%, n = 11), pre-obese (18.5%, n = 38), obese class 1 (18.8%, n = 16), obese class 2 (32.4%, n = 11), and obese class 3 (40.0%, n = 8) (P < 0.01). Controlling for demographic, psychological, and medical/obstetric factors, prepregnancy class-2 (aOR 2.87, 95% CI 1.21-6.81) and class-3 (aOR 3.94, 95% CI 1.38-11.23) obesity remained strongly associated with screening positive for postpartum depression, compared with women of normal weight.

CONCLUSIONS

Self-reported prepregnancy obesity may be associated with screening positive for depression when measured postpartum.

Differences Between Hospitals in Cesarean Rates for Term Primigravidas With Cephalic Presentation

OBJECTIVE

The purpose of this study was to quantify patient populations and practice patterns at perinatal centers with the highest and lowest cesarean delivery rates.

METHODS

The 2 perinatal centers in our state with the lowest (Hospital A-16.6%) and highest (Hospital B-20.3%) overall cesarean rates for Robson group 1 (term primigravidas, vertex, spontaneous labor) and group 2 (term primigravidas, vertex, induced labor) were identified. A total of 174 medical records at Hospital A and 150 records at Hospital B were reviewed. Statistical analysis was performed using independent-sample t tests, chi(2), and multiple logistic regression.

RESULTS

Indications for cesarean delivery were not different between the 2 groups, with the majority being for failure to progress in labor and nonreassuring fetal status. There were no differences between groups in rates of postpartum hemorrhage, chorioamnionitis, or endometritis. There were no differences in neonatal outcomes. Although women delivering in hospital A were not more likely to receive oxytocin augmentation (P = .291), their mean maximal oxytocin dosage was higher (14.5 units compared with 11.6 units, P < .001), and they were more likely to receive both fetal scalp electrodes (60.9% compared with 37.3%, P < .001) and intrauterine pressure catheters (63.8% compared with 26.0%, P < .001).

CONCLUSION

Because safe reduction in cesarean delivery rates for primigravidas will proportionately reduce the number of repeat cesarean delivery required, benchmarking practices as described in this study can be considered in obstetric practices interested in long-term reductions of their cesarean delivery rates.

Population-based trends and correlates of maternal overweight and obesity, Utah 1991-2001

OBJECTIVE

This study aims to identify recent population-based trends in maternal overweight and obesity and adverse outcomes.

STUDY DESIGN

Statewide retrospective cohort study of birth certificate data for live singleton births to women in Utah between 1991 and 2001.

RESULTS

Prepregnancy overweight and obesity increased from 25.1% in 1991 to 35.2% in 2001, a 40.2% increase (prevalence ratio [PR] 1.40 [1.37-1.43]), whereas maternal obesity at delivery rose 36.2% from 28.7% to 39.1% (PR 1.36 [1.33-1.39]). The attributable fraction of cesarean delivery in overweight and obese women was 0.388 (0.369-0.407). Statewide, among all women having a cesarean delivery in 2001, 1 in 7 is attributable to overweight and obesity.

CONCLUSION

This is the first state-wide analysis of maternal obesity trends demonstrating a significant increase in maternal overweight and obesity. Overweight and obese women are at increased risk of cesarean delivery, preeclampsia, eclampsia, dystocia, and macrosomia, risks that increase as the body mass index rises.

Retained fragments after total laparoscopic hysterectomy

A 36-year-old woman had a history of worsening menorrhagia, refractory to medical therapy. She underwent a total laparoscopic hysterectomy. Postoperatively, she experienced significant dyspareunia, dysuria, and pelvic pain. Ten months after her initial procedure, laparoscopy revealed several parasitized fragments of uterine and cervical origin in the pelvis. As laparoscopic morcellation is performed with increased frequency, the need to understand its sequelae has also increased. A concern of morcellating tissue within the abdomen is the fate of fragments inadvertently left behind.

Recurrent Fetal Aneuploidy and Recurrent Miscarriage

OBJECTIVE

Some investigators have found a high frequency of abortus aneuploidy in women with recurrent miscarriage, suggesting the possibility of recurrent aneuploidy as a cause of recurrent miscarriage. Others contend that aneuploidy is not a cause of recurrent miscarriage. The purpose of this study was to investigate the relationship between fetal aneuploidy and recurrent miscarriage by estimating whether fetal aneuploidy is more common in patients with recurrent miscarriage than in patients with sporadic miscarriage

METHODS

Recurrent miscarriage cases (n = 135) included women who had a subsequent miscarriage in which an abortus karyotype was obtained. Controls (n = 150) were patients experiencing a sporadic miscarriage who had fetal karyotypes performed as part of a study to assess the utility of abortus tissue for transplantation. Karyotype analysis was performed using standard G-banding techniques.

RESULTS

Abortuses from 122 cases and 133 controls were successfully karyotyped. Thirty-one (25.4%) abortuses from cases and 56 (42.1%) from controls were aneuploid (odds ratio 0.47, 95% confidence interval 0.27-0.80). Aneuploid abortuses occurred in 20% of cases and 25% of controls, aged 20-29 years, 19% of cases and 24% of controls, aged 30-34 years, 35% of cases and 47% of controls, aged 35-39 years, and 50% of both cases and controls, aged 40 years or older (not significant). Of 30 cases in whom 2 or more miscarriages were karyotyped, 3 (10%) had aneuploidy in each abortus.

CONCLUSION

In our population of recurrent miscarriage patients, abortus aneuploidy occurred significantly less often than in sporadic miscarriages. The rate of aneuploidy in this study was considerably lower than reported in other studies. If recurrent aneuploidy contributes to recurrent miscarriage, it does so in only a small number of patients.

A comparison of two models of gynecology service consultation to the emergency department in an academic medical center

OBJECTIVE

This study was undertaken to determine differences in resource use and outcomes when emergency department (ED) physicians consult the gynecology service routinely versus selectively.

STUDY DESIGN

In July 2000, an ED policy of "routine" gynecology consultation for pregnant women less than 20 weeks' gestation with pain and/or bleeding complaints changed to a policy of "selective" consultation. Resource use and outcomes were compared for 222 women who received care during the 9 months before the protocol change with 268 women who presented during the 9 months after the protocol change.

RESULTS

With selective consultation, patients receiving gynecology evaluations decreased from 74% to 39%. Return visits to the ED increased from 9% to 21%. Ultrasound studies performed by ED physicians and radiologists increased, whereas studies by gynecologists decreased. Patients waited longer and received more unnecessary human chorionic gonadotropin studies.

CONCLUSION

A policy of selective gynecology consultation, compared with routine gynecology consultation in the ED, increases diagnostic study resource use and patient length of stay.
