BackgroundThe rate of induction of labor in the U.S. has risen from 9.6% in 1990 to 25.7% in 2018, including 31.7% of first-time births. Recent studies that have examined inductions have been small qualitative studies or relied on either medical records or administrative data. This study examines induction from the perspective of those women who experienced it, with a particular focus on the prevalence and predictors of inductions for nonmedical indications, women’s experience of pressure to induce labor and the relationship between the attempt to medically initiate labor and cesarean section.MethodsStudy data are drawn from the 2119 respondents to theListening to Mothers in Californiasurvey who were planning to have a vaginal birth in 2016. Mothers were asked if there had been an attempt to medically initiate labor, if it actually started labor, if they felt pressured to have the induction, if they had a cesarean and the reason for the induction. Reasons for induction were classified as either medically indicated or elective.ResultsAlmost half (47%) of our respondents indicated an attempt was made to medically induce their labor, and 71% of those attempts initiated labor. More than a third of the attempts (37%) were elective. Attempted induction overall was most strongly associated with giving birth at 41+ weeks (aOR 3.28; 95% C.I. 2.21–4.87). Elective inductions were more likely among multiparous mothers and in pregnancies at 39 or 40 weeks. The perception of being pressured to have labor induced was related to higher levels of education, maternal preference for less medical intervention in birth, having an obstetrician compared to a midwife and gestational ages of 41+ weeks. Cesarean birth was more likely in the case of overall induction (aOR 1.51; 95% C.I. 1.11–2.07) and especially following a failed attempt at labor induction (aOR 4.50; 95% C.I. 2.93–6.90).ConclusionClinicians counselling mothers concerning the need for labor induction should be aware of mothers’ perceptions about birth and engage in true shared decision making in order to avoid the maternal perception of being pressured into labor induction.

Objective Our objective was to describe patient-, provider-, and health systems-level factors associated with likelihood of obtaining guideline-recommended follow-up to prevent or mitigate early-onset type 2 diabetes after a birth complicated by gestational diabetes mellitus (GDM). Methods This study presents a retrospective cohort analysis of de-identified demographic and health care system characteristics, and clinical claims data for 12,622 women with GDM who were continuously enrolled in a large, national U.S. health plan from January 31, 2006, to September 30, 2012. Data were obtained from the OptumLabs Data Warehouse. We extracted 1) known predictors of follow-up (age, race, education, comorbidities, GDM severity); 2) novel factors that had potential as predictors (prepregnancy use of preventive measures and primary care, delivery hospital size); and 3) outcome variables (glucose testing within 1 and 3 years and primary care visit within 3 years after delivery). Results Asian ethnicity, higher education, GDM severity, and delivery in a larger hospital predicted greater likelihood of post-GDM follow-up. Women with a prepregnancy primary care visit of any type were two to three times more likely to receive postpartum glucose testing and primary care at 1 year, and 3.5 times more likely to have obtained testing and primary care at 3 years after delivery. Conclusions A history of use of primary care services before a pregnancy complicated by GDM seems to enhance the likelihood of postdelivery surveillance and preventive care, and thus reduce the risk of undetected early-onset type 2 diabetes. An emphasis on promoting early primary care connections for women in their early reproductive years, in addition to its overall value, is a promising strategy for ensuring follow-up testing and care for women after complicated pregnancies that forewarn risk for later chronic illness. Health systems should focus on models of care that connect primary and reproductive/maternity care before, during, and long after pregnancies occur.

Objectives Complications of pregnancy such as gestational diabetes mellitus (GDM) forewarn future chronic illness and disability, and demonstrate the need for a life course approach to prevention. Our study had two aims: (1) to elucidate how experiences reported by patients and providers converge to facilitate or impede follow-up care after GDM, and (2) to elicit recommendations for system-level changes to enhance prevention across key care transitions. Methods We conducted in-depth interviews with 30 GDM patients and 29 providers of maternity, specialty and primary care in an urban safety hospital network, and used a three-tiered thematic analysis to interpret their narratives. Results Findings reveal that a 'perfect storm' gathers on the path to prevention across stages of care. At diagnosis, patients feel profound anxiety about the debilitating effects of type 2 diabetes mellitus in their communities, providers choose reassurance over risk communication, and both focus primarily on the birth of a healthy baby. Providers report that clinical teams often lack coordination, and confuse patients with a barrage of often-inconsistent advice. In the postpartum period, providers juggle competing clinical priorities and mothers juggle overwhelming demands; for both, the recommended 2-h oral glucose tolerance test is too arduous for women and providers to do as prescribed. Finally, the transition from maternity to primary care is complicated by communication barriers between clinicians and patients, and between maternity and primary care providers. Conclusions for Practice Respondents propose systems innovations to open communication between provider specialties in order to bridge the chasm between reproductive care and life course prevention.

Objective To implement a standardized universal substance use screening process in an outpatient prenatal clinic at an urban tertiary care hospital. Methods Using a quality-improvement framework that involved process modeling, stakeholder analyses, and plan-do-study-act cycles, we implemented universal substance use screening for prenatal patients using a modified 5Ps screening tool (Parents, Peers, Partner, Past, Present). Implementation included an operational workflow based on the SBIRT (Screening, Brief Intervention, Referral to Treatment) model. The primary outcome measure was percentage of patients who were screened for substance use, with a goal of 90% screened. Secondary outcome measures were percentage who screened positive and percentage of the time a positive screen resulted in documentation of a brief intervention by a health care practitioner. Results Over a 19-month implementation period, 733 patient encounters were sampled. A substance use screen was completed in 618 (84%). We exceeded our goal of screening 90% of eligible patients for the final 6 months of data collection. Of the 618 completed screens, 124 (20%) screened positive. Health care practitioner documentation of brief interventions for patients with a positive screen reached 80% in the final phase of implementation, but then declined to 50% by the completion of the study period. Conclusion A sustainable and generalizable process to carry out substance use screening within a large prenatal practice is feasible, and assisted with identification of patients not known to be at risk. Further efforts are needed to evaluate how to sustain health care practitioner documentation of intervention in response to positive screens.

Objective The study aimed to compare the quantitative blood loss (QBL) and hemorrhage-related outcomes of pregnant women with and without a coronavirus disease 2019 (COVID-19) diagnosis. Study Design This retrospective cohort study of all live deliveries at Boston Medical Center between April 1, 2020 and July 22, 2020 compares the outcomes of pregnant women with a laboratory-confirmed COVID-19 positive diagnosis and pregnant women without COVID-19. The primary outcomes are QBL and obstetric hemorrhage. The secondary outcomes analyzed were a maternal composite outcome that consisted of obstetric hemorrhage, telemetry-level (intermediate care unit) or intensive care unit, transfusion, length of stay greater than 5 days, or intraamniotic infection, and individual components of the maternal composite outcome. Groups were compared using Student's t-test, Chi-squared tests, or Fisher's exact. Logistic regression was used to adjust for confounding variables. Results Of 813 women who delivered a live infant between April 1 and July 22, 2020, 53 women were diagnosed with COVID-19 on admission to the hospital. Women with a COVID-19 diagnosis at their time of delivery were significantly more likely to identify as a race other than white (p = 0.01), to deliver preterm (p = 0.05), to be diagnosed with preeclampsia with severe features (p Conclusion Pregnant women with COVID-19 diagnosis do not have increased risk for obstetric hemorrhage, increased QBL or risk of maternal morbidity compared with pregnant women without a COVID-19 diagnosis. Further research is needed to describe the impact of a COVID-19 diagnosis on maternal hematologic physiology and pregnancy outcomes. Key Points

Background The prevention of venous thromboembolism (VTE) is a high priority in aesthetic surgery. Abdominoplasty is the aesthetic procedure most commonly associated with VTE, yet the mechanisms for the development of VTE associated with this procedure are unclear. Objectives The purpose of this study was to analyze the incidence and predictors of VTE in patients undergoing abdominoplasty procedures in outpatient surgery centers using data from the Internet Based Quality Assurance Program (IBQAP). Methods IBQAP data from 2001 to 2011 were queried retrospectively to identify abdominoplasty cases and VTE cases. Patient- and procedure-specific variables were analyzed to identify potential predictors of VTE in abdominoplasty. Results Among all outpatient aesthetic surgery cases entered from 2001 to 2011, 414 resulted in VTE, representing a VTE incidence of 0.02%. Of these, 240 (58%) occurred in abdominoplasty cases. Predictors of VTE were age greater than 40 years and BMI greater than 25 kg/m2. Patient sex, duration of anesthesia and surgery, type of anesthesia, type of additional procedure, and number of procedures did not appear to influence the risk of VTE. Importantly, 95.5% of the VTEs identified for this study occurred in patients whose Caprini risk assessment model score was between 2 and 8, which would not be an indication for chemoprophylaxis according to current recommendations. Conclusions Many factors must be considered when determining the true incidence of VTE in abdominoplasty. Research is needed to discover the reason abdominoplasty carries a greater risk compared with other aesthetic surgery procedures so that appropriate steps can be taken to prevent its occurrence and improve the safety of the procedure.

BACKGROUND. Low vitamin D status in pregnancy was proposed as a risk factor of preeclampsia. METHODS. We assessed the effect of vitamin D supplementation (4,400 vs. 400 IU/day), initiated early in pregnancy (10–18 weeks), on the development of preeclampsia. The effects of serum vitamin D (25-hydroxyvitamin D [25OHD]) levels on preeclampsia incidence at trial entry and in the third trimester (32–38 weeks) were studied. We also conducted a nested case-control study of 157 women to investigate peripheral blood vitamin D–associated gene expression profiles at 10 to 18 weeks in 47 participants who developed preeclampsia. RESULTS. Of 881 women randomized, outcome data were available for 816, with 67 (8.2%) developing preeclampsia. There was no significant difference between treatment (N = 408) or control (N = 408) groups in the incidence of preeclampsia (8.08% vs. 8.33%, respectively; relative risk: 0.97; 95% CI, 0.61–1.53). However, in a cohort analysis and after adjustment for confounders, a significant effect of sufficient vitamin D status (25OHD ≥30 ng/ml) was observed in both early and late pregnancy compared with insufficient levels (25OHD

This survey study assesses patients’ self-reported communication experiences with their maternity care clinicians and examines the association of these experiences with women’s reports of feeling pressure to have interventions during delivery.

Background A major contributor to the increase in cesarean deliveries over recent decades is the decline in vaginal births after cesarean (VBAC). Racial and ethnic disparities in other perinatal outcomes are widely recognized, but few studies have been directed toward racial/ethnic differences in VBAC rates. Methods We used the population-based Massachusetts Pregnancy to Early Life (PELL) database to investigate racial/ethnic differences in rates of VBAC for Massachusetts residents with one prior cesarean from 1998 to 2008. Results The overall VBAC rate was 17.3 percent. After adjusting for demographic, behavioral, and medical risk factors, non-Hispanic Asian mothers had a greater likelihood of VBAC than non-Hispanic white mothers (adjusted risk ratio 1.31 [95% CI 1.23–1.39]). No other racial/ethnic group was significantly different from non-Hispanic whites in adjusted analyses. The likelihood of VBAC also decreased with increasing maternal age. Discussion Non-Hispanic Asian women are significantly more likely to have VBAC than non-Hispanic white women. Efforts to reduce cesarean delivery rates in the United States should address these disparities. Future research should investigate factors underlying these differences to ensure that all women have access to appropriate maternity care services.

This study investigates the effect of severity of gestational diabetes (GDM) on likelihood of post-delivery glucose testing and early onset Type 2 diabetes (T2DM). We asked if clinical focus on relative risk (RR), i.e. greater probability of T2DM onset in a higher-severity group, contributes to missed opportunities for prevention among women with lower-severity GDM. A sample of 12,622 continuously-insured women with GDM (2006–2015) was drawn from a large national dataset (OptumLabs® Data Warehouse) and followed for 3-years post-delivery. Higher-severity GDM was defined as addition of hypoglycemic therapy to standard of care for GDM. We found that women with higher-severity (n = 2627) were twice as likely as lower-severity women (n = 9995) to obtain glucose testing post-delivery. Moreover, 357 (13.6%) of the higher-severity women developed T2DM by year-3 vs. 600 (6.0%) lower-severity women. In an analysis of the population attributable fraction (PAF), defined as the contribution of excess risk to population prevalence, lower-severity women contributed more cases to diabetes rates than higher-risk women (PAF 79% vs. 21%), despite an increased RR in the higher-severity group (13.6% vs. 6.0%, RR 2.26, 95%CI 2.00, 2.56). Projecting out to the 327,950 U.S. deliveries in 2014, we estimate that 9277 higher-severity women (13.6%) and 15,584 lower-severity women (6.0%), will have developed T2DM by 2018. These data demonstrate that lower-severity GDM contributes substantially to the diabetes epidemic. Greater awareness of clinical and cost implications of gaps in follow-up for lower-severity GDM may strengthen the likelihood of post-delivery testing and primary care referral, and thus reinforce the path to prevention.

Background Maternal asthma, uncontrolled asthma, and low vitamin D levels during pregnancy have been individually linked to increased risk of preeclampsia. Objective To investigate the association of history of physician-diagnosed asthma and uncontrolled asthma status during pregnancy with the risk of preeclampsia and the effects of early pregnancy vitamin D concentrations on this relationship. Methods A total of 816 subjects with available pregnancy outcome data and risk factors of interest were analyzed. A group of experienced obstetricians and gynecologists from 3 study centers validated the preeclampsia diagnoses. Vitamin D was measured using the DiaSorin method at 10 to 18 weeks of gestation. The Pregnancy-Asthma Control Test was used to assess asthma control during pregnancy. Criterion-based stepwise variable selection algorithm was applied to investigate the relationships of risk factors of interest (history of asthma diagnosis, uncontrolled asthma during pregnancy, and vitamin D) to preeclampsia. Results The incidence of preeclampsia was not related to the presence of asthma diagnosis (8.9% with vs 7.4% without). The adjusted odds of preeclampsia controlled for maternal serum 25-hydroxyvitamin D (25OHD) concentrations was higher for women with a higher proportion of uncontrolled asthma months per visit during pregnancy (adjusted odds ratio, 3.55; 95% CI, 1.15-13.0). Adjusting for asthma control status during pregnancy, an additional decrease in the associated preeclampsia risk by 7% was observed for a 10-unit (ng/mL) increase in early pregnancy 25OHD levels (adjusted odds ratio10-unit, 0.60; 95% CI, 0.43-0.82) as compared with the previous risk estimate of preeclampsia associated with low maternal 25OHD unadjusted for asthma control status. Conclusions Uncontrolled asthma during pregnancy is associated with an increased risk of preeclampsia. Early pregnancy 25OHD contributes to the association of uncontrolled asthma status with preeclampsia.

Background: Our study assessed the follow-up of gestational diabetes mellitus (GDM) in the postpartum period among a racially and ethnically diverse group of women receiving care in a major urban medical center. Methods: We conducted cross-sectional analysis of clinical and administrative data on women aged 18–44 years who gave birth at Boston Medical Center (BMC) between 2003 and 2009, had GDM, and used BMC for regular care. We calculated the rate of glucose testing by 70 days and by 180 days after delivery and used logistic regression to assess the predictors of testing. Results: By 6 months postpartum, only 23.4% of GDM-affected women received any kind of glucose test. Among these, over half had been completed by 10 weeks but only 29% were the recommended oral glucose tolerance test (OGTT). After accounting for sociodemographic and health service factors, women aged ≤35 years of age and women with a family practice provider were significantly less likely to be tested than their counterparts (odds ratio [OR] 0.51; 95% confidence interval [CI] 0.32, 0.83 and OR 0.36; 95% CI 0.19, 0.71 respectively). Women who attended a primary care visit within 180 days after birth had three times higher odds of being tested than those without such a visit (OR 3.10; 95% CI 1.97, 4.87). Conclusions: Despite widely disseminated clinical guidelines, postpartum glucose testing rates are exceedingly low, marking a critical missed opportunity to launch preventive care for women at high risk of type 2 DM. Failed follow-up of GDM by providers of prenatal and postpartum care also reflects a broader systems failure: the absence of a well-supported transition from pregnancy care to ongoing primary care for women.

Background The United States has recently experienced increases in both its rate of obesity and its cesarean rate. Our objective was to use a new item measuring prepregnancy body mass index (BMI) on the U.S. Standard Certificate of Live Birth to examine at a population level the relationship between maternal obesity and primary cesarean delivery for women at otherwise low risk for cesarean delivery. Methods By 2012, 38 states with 86 percent of United States births had adopted the U.S. Standard Certificate. The sample was limited to the 2,233,144 women who had a singleton, vertex, term (37–41 weeks) birth in 2012 and no prior cesarean. We modeled the likelihood of a primary cesarean by BMI category, controlling for maternal socio-demographic and medical characteristics. Results Overall, 46.4 percent of otherwise low-risk mothers had a prepregnancy BMI in the overweight (25.1%) or obese (21.3%) categories, with the obese category distributed as follows: obese I (BMI 30.0–34.9, 12.4%); obese II (BMI 35.0–39.9, 5.5%); and obese III (BMI 40+, 3.5%). Obesity rates were highest among American Indian and Alaska Native (32.5%) and non-Hispanic black mothers (30.5%). After adjustment for demographic and medical risks, the adjusted risk ratios (95% confidence intervals) of cesarean for low-risk primiparas were: 1.61 (1.60–1.63) for obese I, 1.86 (1.83–1.88) for obese II, and 2.21 (2.18–2.25) for obese III mothers compared with mothers in the normal weight category. Discussion A relationship between prepregnancy obesity and primary cesarean delivery among relatively low-risk mothers remained even after controlling for social and medical risk factors.

Objective: To test the hypothesis that elevated temperature is more common after abdominal myomectomy than after hysterectomy. Design: Retrospective cohort study. Setting: Academic medical center. Patient(s): One hundred one women who underwent abdominal myomectomy and 160 women who underwent total abdominal hysterectomy for benign disease from 1988–1993. Intervention(s): Abdominal myomectomy. Main Outcome Measure(s): Temperature of ≥38.5°C within 48 hours after operation. Result(s): Although univariate analysis showed that the incidence of elevated temperature was slightly greater among patients who underwent myomectomy (33% versus 26%, relative risk 1.29, 95% confidence interval 0.88–1.90), multivariate logistic regression analysis showed a 3.29 relative risk of elevated temperature (95% confidence interval 1.56–6.96) with myomectomy after controlling for age, parity, estimated blood loss, and treatment by the general gynecology service. Conclusion(s): After controlling for confounders, myomectomy was found to be an independent predictor for fever in the first 48 hours after operation.

Objective : To compare the morbidity of total abdominal hysterectomy and abdominal myomectomy in the surgical management of uterine leiomyomas. Methods : Hospital records were reviewed for all women who underwent hysterectomy ( n = 89) or myomectomy ( n = 103) between May 1, 1988, and May 1, 1993, for the preoperative diagnosis of leiomyoma. Results : There were significant differences between the two groups for average age (hysterectomy 39.2 years, myomectomy 34.4 years; mean difference 4.8, 95% confidence interval [CI] of difference 3.7–5.9), uterine size (hysterectomy 15.2, myomectomy 11.5 weeks; mean difference 3.8, 95% CI of difference 2.0–5.4) and use of a GnRH agonist (hysterectomy 23.6%, myomectomy 55.3%; relative risk [RR] 0.4, 95% CI 0.3–0.6). Myomectomy was associated with decreased estimated blood loss (hysterectomy 796 mL, myomectomy 464 mL; mean difference 331, 95% CI 121–542) and febrile morbidity (risk of temperature 38C or 48 or more hours postoperatively: for hysterectomy 49.4%, for myomectomy 32%; RR 1.5, 95% CI 1.1–2.2). Using multivariate linear regression, estimated blood loss was similar between the groups after controlling for uterine size. There was no difference in blood transfusion rates. There were two ureteral, one bladder, one bowel, and one femoral nerve injury in the hysterectomy group, and there were no intraoperative visceral injuries in the myomectomy group. Conclusion : Myomectomy compares favorably to hysterectomy in the surgical management of leiomyomas, with a possible decreased risk for visceral injury and infection.

Several factors may increase a patient's risk for perioperative pulmonary complications.

Procedural and patient-related risk factors are discussed, as are recommendations for perioperative management and strategies for minimizing complications.

The American Association for Accreditation of Ambulatory Surgery Facilities (AAAASF) has reported statistics on morbidity and mortality for facilities that it accredits based on an analysis of unanticipated sequelae and surgical mortality. Data acquired through the first Internet-Based Quality Assurance and Peer Review reporting system (IBQAP) were reviewed and published in 2004. This article reports the accumulated data in the IBQAP through June of 2006, analyzing death associated with procedures performed in facilities approved by the AAAASF. With the exception of some statistics on the Medicare-aged population, there are few data reported in the literature related to deaths in outpatient surgery.The IBQAP, designed in 1999 by the AAAASF, mandates biannual reporting of all unanticipated sequelae and random case reviews by all surgeons operating in AAAASF-accredited facilities. Surgical log numbers, whose entry is required, allow for tabulation of the number of cases and procedures performed by individual reporting surgeons.In this review of data collected using the IBQAP from January of 2001 through June of 2006, there were 23 deaths in 1,141,418 outpatient procedures performed. Pulmonary embolism caused 13 of the 23 deaths. Only one death occurred as the result of an intraoperative adverse event.A pulmonary embolism may occur after any operative procedure, whether it is performed in a hospital, an ambulatory surgery center, or a physician's office-based surgery facility. The procedure most commonly associated with death from pulmonary embolism in an office-based surgery facility is abdominoplasty. The frequency of pulmonary embolism associated with abdominoplasty warrants further study to determine predisposing factors, understand its cause, and introduce guidelines to prevent its occurrence.

Importance Asthma and wheezing begin early in life, and prenatal vitamin D deficiency has been variably associated with these disorders in offspring. Objective To determine whether prenatal vitamin D (cholecalciferol) supplementation can prevent asthma or recurrent wheeze in early childhood. Design, Setting, and Participants The Vitamin D Antenatal Asthma Reduction Trial was a randomized, double-blind, placebo-controlled trial conducted in 3 centers across the United States. Enrollment began in October 2009 and completed follow-up in January 2015. Eight hundred eighty-one pregnant women between the ages of 18 and 39 years at high risk of having children with asthma were randomized at 10 to 18 weeks’ gestation. Five participants were deemed ineligible shortly after randomization and were discontinued. Interventions Four hundred forty women were randomized to receive daily 4000 IU vitamin D plus a prenatal vitamin containing 400 IU vitamin D, and 436 women were randomized to receive a placebo plus a prenatal vitamin containing 400 IU vitamin D. Main Outcomes and Measures Coprimary outcomes of (1) parental report of physician-diagnosed asthma or recurrent wheezing through 3 years of age and (2) third trimester maternal 25-hydroxyvitamin D levels. Results Eight hundred ten infants were born in the study, and 806 were included in the analyses for the 3-year outcomes. Two hundred eighteen children developed asthma or recurrent wheeze: 98 of 405 (24.3%; 95% CI, 18.7%-28.5%) in the 4400-IU group vs 120 of 401 (30.4%, 95% CI, 25.7%-73.1%) in the 400-IU group (hazard ratio, 0.8; 95% CI, 0.6-1.0; P = .051). Of the women in the 4400-IU group whose blood levels were checked, 289 (74.9%) had 25-hydroxyvitamin D levels of 30 ng/mL or higher by the third trimester of pregnancy compared with 133 of 391 (34.0%) in the 400-IU group (difference, 40.9%; 95% CI, 34.2%-47.5%, P Conclusions and Relevance In pregnant women at risk of having a child with asthma, supplementation with 4400 IU/d of vitamin D compared with 400 IU/d significantly increased vitamin D levels in the women. The incidence of asthma and recurrent wheezing in their children at age 3 years was lower by 6.1%, but this did not meet statistical significance; however, the study may have been underpowered. Longer follow-up of the children is ongoing to determine whether the difference is clinically important. Trial Registration clinicaltrials.gov Identifier:NCT00920621

We have treated more than 250 cases of impotence by inserting a penile rod. The implant has been modified intermittently, and it currently consists of a two-piece rod with a Y-shaped proximal portion to provide greater stability. Most of the patients we treated have been satisfied with the results of the surgery, and would have it repeated. Therefore, we feel that this prosthesis is an excellent one for treating male impotence.

Summary One hundred and two cases of keratoacanthoma were reviewed. Fourteen cases were selected for brief reports to demonstrate the danger in the diagnosis of keratoacanthoma. The danger lies in the treatment of keratoacanthoma as benign when it is probably premalignant and closely associated with squamous cell carcinoma. This has influenced us to recommend wide excision as the primary treatment of all cases of keratoacanthoma.
