To investigate whether the 2010 introduction of percutaneous tibial nerve stimulation and the 2013 introduction of intradetrusor onabotulinumtoxinA were associated with an increase in overall utilization of third-line treatments.Using medical claims data from IBM Marketscan database 2010-2019, diagnosis codes were used to identify adult women with overactive bladder. Procedure codes were used to identify third-line treatments. The annual proportion of patients receiving third-line treatments was calculated, as well as the proportion of each treatment received. These were modeled as a function of treatment year using linear regression; a regression coefficient significantly different from zero was considered evidence of a significant change in utilization over time.We identified 3,067,515 unique individuals with a diagnosis of overactive bladder, including 14,652 who initiated third-line treatments. The annual percentage of women with overactive bladder who initiated third-line treatment was 0.18% and did not change significantly over 10 years (p=0.82). However, the proportion receiving sacral neuromodulation decreased significantly (p0.001), with a compensatory increase in intradetrusor onabotulinumtoxinA. Specifically, within 6 years of its introduction, onabotulinumtoxinA accounted for almost half of third-line treatments initiated.Overall, third-line therapies for non-neurogenic overactive bladder are utilized infrequently among privately insured women. Over the past decade, the introduction of new treatment options has led to a shift in the type of treatment initiated, rather than to an increase in the overall utilization of third-line therapies.

The aims of this study were to estimate the incidence of repeated evaluations for urinary tract infection (UTI) after a single occurrence and to identify characteristics associated with repeated evaluations in a female Medicare population.This was a case-control study of women aged 65 years or older undergoing incident outpatient evaluation for UTI between the years of 2011 and 2018. We defined UTI evaluation as an outpatient encounter with diagnostic codes for UTI and an order for urine culture. We excluded women with diagnostic codes suggestive of a complicated UTI. Among all women with an incident UTI evaluation, cases were defined as those with repeated evaluations, defined as either a total of ≥2 UTI evaluations in 6 months and/or ≥3 in 1 year. The characteristics of cases versus controls were compared with both an unadjusted and adjusted logistic regression model.Our overall cohort consisted of 169,958, of which 13,779 (8.1%) had repeated evaluations for UTI. In unadjusted analyses, cases were more likely to be older than 75 years, of White race, and to have cardiovascular conditions, diabetes, dementia, renal disease, and chronic obstructive pulmonary disease (all P's0.01) as compared with controls. In adjusted analysis, ages 75 years to 84 years (P0.01) and ages older than 84 years (P0.01) along with multiple medical comorbidities were significant risk factors for repeated evaluations for UTI. Black women had lower odds of repeated evaluations for UTI (P0.01).Among women with a single UTI evaluation, repeated evaluations for UTI were associated with older age, White race, and medical comorbidities. Future studies should investigate racial disparities seen in care-delivery behavior and/or care-seeking behavior.

Background In vitro fluconazole resistance in vaginal C. albicans has rarely been reported in the U.S. Little is known about the characteristics of patients who demonstrate fluconazole resistance vs. sensitivity, or how likely resistant strains are to persist over time. Hence we sought to describe patterns of fluconazole resistance in clinician ordered vaginal cultures positive for C. albicans at our center. We compared patient characteristics between those with fluconazole sensitive versus resistant isolates. Methods We conducted a chart review of patients with clinician ordered vaginal cultures positive for C. albicans undergoing fluconazole susceptibility testing in our medical center’s clinical mycology lab from January 2017 to April 2021. Patient characteristics were compared using chi-square and ANOVA tests and correlated to fluconazole resistance with logistic regression models. Results Of N=92 patients with vaginal C. albicans, 3.3% were sensitive dose-dependent (SDD: minimal inhibitory concentration (MIC) =4) to fluconazole, and 30.4% were resistant (R: MIC > =8). Amongst those with at least 2 previous episodes of vulvovaginal candidiasis (VVC) in the past 6 months (N=45), 50% had R and 6.5% had SDD isolates. Compared to those with sensitive (S: MIC < =2) isolates, patients with SDD or R were younger and more likely to have the following characteristics: Black race, bacterial vaginosis (BV) in the past year, high or multi-dose azole treatment, fluconazole suppressive therapy in the past 6 months, and more VVC and BV episodes in the previous 6 months (Table 1). Of N=10 patients who had a follow-up culture with initial R isolates, 28.6% had a sensitive C. albicans vaginal isolate. Conclusion The frequency of C. albicans vaginal isolates with in vitro resistance to fluconazole in this study was high. Our findings highlight the importance of obtaining cultures and sensitivity testing in patients with recurrent or refractory VVC. However, resistant vaginal strains may not necessarily persist over time. Future, larger studies on those with recurrent VVC are needed to verify factors associated with fluconazole resistance, how frequently azole-resistant strains persist over time, and how well in vitro resistance correlates to in vivo treatment response.

Objectives To summarize the published literature regarding pelvic organ prolapse, dehiscence or evisceration, vaginal fistula, and dyspareunia after radical cystectomy and to describe the management approaches used to treat these conditions. Methods Ovid MEDLINE, Ovid EMBASE, and Web of Science were systematically searched from January 1, 2001 to January 25, 2021 using a combination of search terms for bladder cancer and radical cystectomy with terms for four categories of vaginal complications (prolapse, fistula, evisceration/dehiscence, and dyspareunia). A total of 229 publications were identified, the final review included 28 publications. Results Neobladder vaginal fistula was evaluated in 17 publications, with an incidence rate of 3 – 6% at higher volume centers, often along the anterior vaginal wall at the location of the neobladder-urethral anastomosis. Sexual function was evaluated in 10 studies, 7 of which utilized validated instruments. Maintaining the anterior vaginal wall and the distal urethra appeared to be associated with improved sexual function. Pelvic organ prolapse was assessed in 5 studies, only 1 used a validated questionnaire and none included a validated objective measure of pelvic organ support. Conclusion There is a need for more prospective studies, using standardized instruments and subjective outcome measures to better define the incidence of vaginal complications after radical cystectomy for bladder cancer, and to understand their impact on quality of life measures.

Despite the prevalence of anxiety, its impact on postoperative pain remains poorly characterized. The present study was aimed at assessing the impact of preoperative anxiety on postoperative pain in patients undergoing pelvic reconstructive surgery. We hypothesized that greater anxiety would be associated with increased postoperative pain for patients undergoing pelvic reconstructive surgery.This was a prospective multi-center observational study in Baltimore between September 2018 and June 2019. The Beck Anxiety Inventory was used to assess preoperative anxiety and the validated Surgical Pain Scale instrument was used to assess pain in the postoperative period. The association between anxiety and postoperative pain was analyzed using multivariate logistic regression, adjusting for relevant confounders.A total of 149 patients undergoing pelvic reconstructive surgery completed preoperative surveys. The median age of the study population was 59. The prevalence of preoperative anxiety (anxiety score9) in our study population was 26.8% (95% CI 19.7-34.0%). Women with preoperative anxiety reported higher postoperative pain on days 1-2 (relative odds 1.05, 95% confidence interval 1.01-1.10) and day 14 (relative odds 1.53, 95% confidence interval 1.00-2.34).A large fraction of women undergoing pelvic reconstructive surgery have moderate to severe preoperative anxiety. Women with preoperative anxiety appear to have greater odds of increased postoperative pain. Understanding this association may help surgeons with preoperative counseling and expectations regarding postoperative pain.

One third of women receive opioids after hysteroscopy; opioid dispensing practices varied significantly by facility type and region.

An enlarged genital hiatus (GH) is associated with the development of prolapse and may be associated with prolapse recurrence following surgery; however, there is insufficient evidence to support surgical reduction of the GH as prophylaxis against future prolapse. The objective of this review is (1) to review the association between GH size and pelvic organ prolapse and (2) to discuss the existing literature on surgical procedures that narrow the GH. A literature search was performed in the PubMed search engine, using the keyword “genital hiatus.” Articles were included if they addressed any of the following topics: (1) normative GH values; (2) associations between the GH and prolapse development or recurrence; (3) surgical alteration of the GH; (4) indications, risks or benefits of surgical alteration of the GH. An enlarging GH has been observed prior to the development of prolapse. Multiple studies show that an enlarged pre- and/or postoperative GH is associated with an increased risk of recurrent prolapse following prolapse repair surgery. There are limited data on the specific risks of GH alteration related to bowel and sexual function. GH size and prolapse appear to be strongly associated. Because GH size appears to be a risk factor for pelvic organ prolapse, the GH size should be carefully considered at the time of surgery. Surgeons should discuss with their patients the risks and potential benefits of additional procedures designed to reduce GH size.

OBJECTIVES: In cross-sectional studies, pelvic organ prolapse is strongly associated with genital hiatus size. The objective of this study was to estimate prolapse incidence by the size of the genital hiatus among parous women followed prospectively. METHODS: Data were derived from a longitudinal study of pelvic floor disorders. Participants were followed annually for 2–9 years. Genital hiatus size and prolapse beyond the hymen were assessed with annual POP-Q examinations. Kaplan-Meier methods described prolapse-free survival as a function of genital hiatus size. Accounting for changes over time in genital hiatus size, lognormal models were used to estimate prolapse-free survival by genital hiatus size. This analysis was repeated separately for women who delivered exclusively by cesarean versus those with at least one vaginal birth RESULTS: Among 1492 participants, median age at enrollment was 38 years; 153 (10.3%) developed POP over 2–9 years. The cumulative probability of prolapse increased substantially as the size of the genital hiatus increased. Lognormal models predicted that the estimated median time to develop prolapse would be 33.4 years for women with a persistent genital hiatus of 3cm; in contrast, the estimated median time to develop prolapse would be 5.8 years for a genital hiatus of ≥4.5 cm. Considering separately women who delivered by cesarean versus those with at least one vaginal birth, genital hiatus size drastically modified prolapse risk in both birth groups. CONCLUSIONS: Prolapse incidence is strongly associated with genital hiatus size, regardless of delivery mode. These findings suggest that a wider GH is an important predictor of future prolapse risk.

Pelvic organ prolapse (POP) severity is poorly correlated with prolapse symptoms. The objective of this study was to investigate the association between genital hiatus (GH) size and presence and severity of bulge symptoms. This analysis utilized data from a longitudinal study of parous women. Women underwent annual assessment of POP, GH size, and bulge symptoms. “Bother” was scored by participants reporting bulge symptoms. Three analyses evaluated the association between GH size and bulge symptoms, each using linear mixed models. First, we compared case visits (bulge symptoms reported) to control visits (bulge symptoms never reported), matching for stage. Second, among women who reported bulge sensation at least once during the study, we compared GH size at visits with and without bulge symptoms. Third, among women who reported bulge sensation, we investigated whether GH size was associated with “bother” score, controlling for stage. Of 1528 women (7440 visits), 148 women (803 visits) reported bulge symptoms at ≥ 1 visit and 1380 women never reported bulge symptoms (6637 visits). Comparing 315 case visits (bulge symptoms reported) to 1260 control visits (bulge symptoms never reported), GH size was significantly greater among case visits (3.05 cm versus 2.85 cm, p ≤ 0.0001). In the case-crossover analysis, GH size was similar for visits with and without bulge symptoms (p = 0.63). When evaluating GH size and degree of bulge symptom bother, bother severity was significantly associated with GH size (p = 0.003). Independent of stage, GH size was significantly associated with prolapse bulge symptoms and bother severity.

Although the peak incidence of surgery for pelvic floor disorders does not occur until after menopause, an increasing number of younger women are seeking treatment for these problems. Whereas most surgeons would recommend delaying surgery until the completion of childbearing, published cases and case series address outcomes after subsequent pregnancies in women who have been treated for urinary incontinence and pelvic organ prolapse. This document synthesizes the available evidence on the impact of pregnancy on women with prior treatment for pelvic floor disorders and on the impact of these prior treatments on subsequent pregnancy. Pregnancy after the repair of obstetrical anal sphincter laceration is also discussed. Consensus recommendations are presented based on available literature review and expert involvement.

INTRODUCTION AND HYPOTHESIS: To investigate the relationship between race and anal incontinence (AI). Our hypotheses were (a) AI symptoms are similar between white and black women and (b) asymptomatic black and white women are equally likely to develop AI over one year of prospective observation. METHODS: Parous women enrolled in a longitudinal cohort study were assessed for AI symptoms annually using Epidemiology of Prolapse and Incontinence Questionnaire. An AI score >0 indicated any bother from AI; a score >22.8 indicated clinically significant AI. We compared the odds of AI scores >0 at the visit level between white vs black women with logistic regression models using generalized estimating equations. We also estimated the odds of new AI symptoms at time T+1(one year later) among women free of AI symptoms at time T comparing white vs black women. In the latter analysis, we considered new AI symptoms to be represented by scores above 11.4. Covariates included in the adjusted models were: mode of delivery, obstetrical anal sphincter injuries, body mass index, age at the first delivery, and parity at enrollment. RESULTS. Among 1256 participants, 189 (15.0%) were black. AI score= 0 was observed at 74.2% (= 5122/6902) person-visits. The adjusted odds ratio of AI score >0 was 1.83 (95% CI 1.24, 2.70) for white vs black women. Across 4364 visit pairs with AI score =0 at time T, 203 (4.7%) had AI score >11.4 at visit T+1 and white race significantly increased the odds of developing symptoms at time T+1 (adjusted OR= 2.26, 95% CI 1.28, 3.98). CONCLUSIONS. In an analysis that controlled for mode of delivery, obstetrical anal sphincter injuries, obesity, age at first delivery, and parity, white race was significantly associated with AI symptoms at any point in time as well as to the development of AI over one year of observation.

Cystectomy with a vaginal-sparing approach may be associated with unique complications specific to the female population. The objective of this study was to estimate the incidence of vaginal complications (defined to include vaginal prolapse, vaginal fistula, dyspareunia and vaginal cuff dehiscence/evisceration) after cystectomy and to determine risk factors for these complications.Women 65 years or older undergoing cystectomy for any indication were identified by procedural codes in the Medicare Limited Data Set 5% sample from January 1, 2011 to December 31, 2017. Patients experiencing a vaginal complication after cystectomy were compared to those who did not. Demographic and biological factors that could increase likelihood of complications were identified and time to development of complications determined. Cumulative incidence was calculated using cumulative incidence function. Multivariable cause-specific Cox proportional hazards model assessed risk factors for vaginal complications.In all, 481 women undergoing cystectomy were identified during the study period, and 37.2% were younger than 70 years old. The majority (378, 79%) had bladder cancer, and 401 (83.4%) underwent an incontinent conduit or catheterizable channel diversion. Within 2 years of cystectomy, 93 patients (19.5%) had 1 or more complications on record. Vaginal cuff dehiscence had the highest cumulative incidence, occurring in 49 patients (10.2%). Over the entire study period (2011-2017), 102 women (21.2%) were diagnosed with a vaginal complication, and 27 (5.6%) received an intervention.Among women who undergo cystectomy, vaginal complications occur at rates higher than expected with over 20% of women experiencing a complication and over a quarter of those diagnosed undergoing intervention.

OBJECTIVE To evaluate effects of frailty and hysterectomy route on 30-day postoperative morbidity for older hysterectomy patients. METHODS Participants included patients in the American College of Surgeons' National Surgical Quality Improvement Program database aged 60 years or older and undergoing simple hysterectomy from 2014 to 2018. The Five-Factor Modified Frailty Index approximated frailty: women with scores of 3 or more, indicating more severe comorbidities, were considered frail. Logistic regression multivariable models with and without an interaction term were used to study the independent and interactive effects of frailty and route on postoperative complications. RESULTS Of 19 888 hysterectomies, 4356 (21.9%) were abdominal, 13 382 (67%) were laparoscopic, and 2150 (10.8%) were vaginal, with 251 (1.3%) frail patients. Frailty (odds ratio [OR] 1.89, 95% confidence interval [CI] 1.32-2.70, P = 0.001) and abdominal versus laparoscopic hysterectomy (OR 2.14, 95% CI 1.88-2.45, P

Intravaginal boric acid (IBA) represents one of the only options available to treat azole-resistant vulvovaginal candidiasis (VVC) and is included as part of multiple national guidelines (including the United Kingdom and the United States) for the treatment of VVC or recurrent bacterial vaginosis. Novel products using IBA are under development for treatment and suppression of VVC and bacterial vaginosis. Use of over-the-counter or clinician-prescribed IBA in reproductive-aged women is already widespread and may increase further if drug resistance in VVC rises. However, IBA is not a Food and Drug Administration-approved drug, and safety data are sparse. Given these factors, it is important to understand the currently available data on the safety of IBA use. Herein, we set out to synthesize human and animal data (converting, where appropriate, dose and serum values to standard units to facilitate comparison) to answer 2 key questions: (1) What are the data on the safety of IBA use for women? and (2) What are the data on the safety of IBA use in pregnancy? We find that, despite gaps, available data suggest IBA use is safe, at least when used in doses commonly described in the literature as being prescribed by clinicians. Information on harms in pregnancy is limited, and data remain insufficient to change current guidelines, which recommend IBA avoidance in pregnancy.

We aimed to explore relationships between changes in genital hiatus (GH) and development of pelvic organ prolapse using data from the Mothers’ Outcomes After Delivery (MOAD) Study, a Baltimore, Maryland, cohort study of parous women who underwent annual assessments during 2008–2018. Prolapse was defined as any vaginal segment protrusion beyond the hymen or reported prolapse surgery. For each case, 5 controls (matched on birth type and interval from first delivery to study enrollment) were selected using incidence sampling methods. We used a mixed model whose fixed effects described the initial size and slope of the GH as a function of prolapse status (case vs. control) and with nested (women within matched sets) random effects. Among 1,198 women followed for 1.0–7.3 years, 153 (13%) developed prolapse; 754 controls were matched to those women, yielding 3,664 visits for analysis. GH was 20% larger among the cases at enrollment (3.16 cm in cases vs. 2.62 cm in controls; P

This article aims to evaluate the impact of a mentorship program to enhance the training of clinical and research scientists in obstetrics and gynecology (OBGYN). A departmental course was developed for junior faculty and fellows based on their areas of interest. The research was IRB-approved. The curriculum consisted of monthly interactive workshops for an interdisciplinary group of trainees in OBGYN. Themes included research, education, and leadership in academic OBGYN. There was a strong emphasis on participatory exercises. Examples of curriculum topics included manuscript publication and review, grant writing, working with an IRB, promotion, and time management. Pre- and post-course questionnaires assessed participants' confidence in skills related to the course topics. Generalized linear models were used to assess changes in post-course response, using each question as the dependent variable and an indicator for post-course as the predictor variable. The control group was composed of junior faculty and fellows before the course was initiated. Outcome measures included the number and impact factor of published manuscripts. A Wilcoxon rank-sum test was used to assess outcome measures. Of the 118 attendees, 26 (22.0%) were junior faculty, 35 (29.66%) were clinical fellows, and 28 (23.7%) were research fellows, other research staff, or students. For each 3-year course series, an average of 20 participants completed the post-course surveys, of which 72% were clinical fellows, 22% were assistant professors, and 5% were instructors. The data revealed a statistically significant change in the participant's overall confidence in skills related to research, education, and leadership when comparing the cumulative results from the pre-to-post course surveys (p

Objective The aim of this article is to review all litigations involving obstetric anal sphincter injury (OASIS) in the United States to highlight the most common allegations and factors that aided the involved obstetricians and gynecologists (ob/gyns). Methods We used Lexis Nexis, a comprehensive legal database, to search all publicly available high-profile federal and state level litigations related to OASIS. Results Of 68 cases that resulted and reviewed, 19 were deemed to be pertinent to the question being addressed. These 19 cases occurred between 1964 and 2011 and all alleged medical negligence. Among these 19 cases, 6 were ruled in favor of the plaintiffs, with most of them being awarded an amount ranging from US $110,000 to US $841,810.80. All 6 cases involved episiotomy. Thorough medical recordkeeping, comprehensive discharge instructions and counseling, and timely evaluation and referral to a female pelvic medicine and reconstructive surgery specialist were the key factors that aided the ob/gyns facing these litigations. Conclusions Avoidance of episiotomy, thorough medical recordkeeping, comprehensive discharge instruction and counseling, and timely evaluation and referral to a female pelvic medicine and reconstructive surgery specialist may help an ob/gyn prevail in OASIS-related litigations.

INTRODUCTION AND HYPOTHESIS: Connective tissue disorders may contribute to pelvic floor disorders (PFDs). Like PFDs, abdominal wall hernias are more common in patients with systemic connective tissue disorders. We conducted this study to explore the possible association between PFDs and hernias in adult women. METHODS: We obtained the data for this study from a study of PFDs among parous women. At enrollment, stress urinary incontinence (SUI), overactive bladder (OAB), and anal incontinence (AI) were assessed using the Epidemiology of Prolapse and Incontinence Questionnaire (EPIQ) and pelvic organ prolapse (POP) was assessed through the Pelvic Organ Prolapse Quantification (POP-Q) examination. Participants were asked to report hernia surgery and list their hernia types. We compared the prevalence of PFDs in those with and without hernias using chi-square test. We used multiple regression analysis to adjust for obstetric and sociodemographic variables. RESULTS: Among 1529 women, 79 (5.2%) reported history of hernia surgery. The prevalence of POP was 7.6% (6 cases) vs. 7.4% (107 cases), the prevalence of SUI was 7.6% (6 cases) vs. 9.9% (144 cases), the prevalence of OAB was 7.6% (6 cases) vs. 5.7% (83 cases), and the prevalence of AI was 7.6% (6 cases) vs. 10.8% (156 cases) in those with hernias compared to those without hernias, respectively. None of these differences were statistically significant. There was no association between hernias and PFDs after adjustment for type of delivery, number of deliveries, age group, primary racial background, weight category, and smoking status. CONCLUSION: In this study, we could not find any association between hernias and PFDs.

An enlarged genital hiatus (GH) is associated with the development of prolapse and may be associated with prolapse recurrence following surgery; however, there is insufficient evidence to support surgical reduction of the GH as prophylaxis against future prolapse. The objective of this review is (1) to review the association between GH size and pelvic organ prolapse and (2) to discuss the existing literature on surgical procedures that narrow the GH.A literature search was performed in the PubMed search engine, using the keyword "genital hiatus." Articles were included if they addressed any of the following topics: (1) normative GH values; (2) associations between the GH and prolapse development or recurrence; (3) surgical alteration of the GH; (4) indications, risks or benefits of surgical alteration of the GH.An enlarging GH has been observed prior to the development of prolapse. Multiple studies show that an enlarged pre- and/or postoperative GH is associated with an increased risk of recurrent prolapse following prolapse repair surgery. There are limited data on the specific risks of GH alteration related to bowel and sexual function.GH size and prolapse appear to be strongly associated. Because GH size appears to be a risk factor for pelvic organ prolapse, the GH size should be carefully considered at the time of surgery. Surgeons should discuss with their patients the risks and potential benefits of additional procedures designed to reduce GH size.

Objectives The 2016 American Urogynecologic Society Prolapse Consensus Conference brought together thought leaders in the field of pelvic organ prolapse (POP). The goal was to identify critical areas of need for future research. This article summarizes the findings. Methods Prior to the conference, 5 major focus areas were identified. Focus areas were explored over the 2-day conference. Clinicians, clinical and basic science researchers, and representatives from government agencies, industry, patient advocacy groups, and the public convened to identify the major gaps in knowledge in each of these focus areas. Results The 5 major topics were as follows: (1) mechanistic research on pelvic supportive structures and how these are altered with pregnancy, delivery, and aging; (2) novel prostheses or implants that address pathophysiology and provide mechanical support; (3) large-scale community-based research; (4) clinical trials to optimize outcomes after POP surgery; and (5) evidence-based quality measures for POP outcomes. Key recommendations were made for each topic. Conclusions Critical gaps in our knowledge were identified. These limit scientific discovery across all 5 topic areas. Further scientific progress would be advanced by (1) developing a standardized group of POP outcomes and quality measures for large trials and community-based research, (2) creating specimen biorepositories that are integrated with robust clinical data, and (3) developing collaborative teams with expertise from a variety of disciplines, convened to tackle our most challenging and complex scientific questions.

Importance Pelvic floor disorders (eg, urinary incontinence), which affect approximately 25% of women in the United States, are associated with childbirth. However, little is known about the course and progression of pelvic floor disorders over time. Objective To describe the incidence of pelvic floor disorders after childbirth and identify maternal and obstetrical characteristics associated with patterns of incidence 1 to 2 decades after delivery. Design, Setting, and Participants Women were recruited from a community hospital for this cohort study 5 to 10 years after their first delivery and followed up annually for up to 9 years. Recruitment was based on mode of delivery; delivery groups were matched for age and years since first delivery. Of 4072 eligible women, 1528 enrolled between October 2008 and December 2013. Annual follow-up continued through April 2017. Exposures Participants were categorized into the following mode of delivery groups: cesarean birth (cesarean deliveries only), spontaneous vaginal birth (≥1 spontaneous vaginal delivery and no operative vaginal deliveries), or operative vaginal birth (≥1 operative vaginal delivery). Main Outcomes and Measures Stress urinary incontinence (SUI), overactive bladder (OAB), and anal incontinence (AI), defined using validated threshold scores from the Epidemiology of Prolapse and Incontinence Questionnaire, and pelvic organ prolapse (POP), measured using the Pelvic Organ Prolapse Quantification Examination. Cumulative incidences, by delivery group, were estimated using parametric methods. Hazard ratios, by exposure, were estimated using semiparametric models. Results Among 1528 women (778 in the cesarean birth group, 565 in the spontaneous vaginal birth group, and 185 in the operative vaginal birth group), the median age at first delivery was 30.6 years, 1092 women (72%) were multiparous at enrollment (2887 total deliveries), and the median age at enrollment was 38.3 years. During a median follow-up of 5.1 years (7804 person-visits), there were 138 cases of SUI, 117 cases of OAB, 168 cases of AI, and 153 cases of POP. For spontaneous vaginal delivery (reference), the 15-year cumulative incidences of pelvic floor disorders after first delivery were as follows: SUI, 34.3% (95% CI, 29.9%-38.6%); OAB, 21.8% (95% CI, 17.8%-25.7%); AI, 30.6% (95% CI, 26.4%-34.9%), and POP, 30.0% (95% CI, 25.1%-34.9%). Compared with spontaneous vaginal delivery, cesarean delivery was associated with significantly lower hazard of SUI (adjusted hazard ratio [aHR], 0.46 [95% CI, 0.32-0.67]), OAB (aHR, 0.51 [95% CI, 0.34-0.76]), and POP (aHR, 0.28 [95% CI, 0.19-0.42]), while operative vaginal delivery was associated with significantly higher hazard of AI (aHR, 1.75 [95% CI, 1.14-2.68]) and POP (aHR, 1.88 [95% CI, 1.28-2.78]). Stratifying by delivery mode, the hazard ratios for POP, relative to a genital hiatus size less than or equal to 2.5 cm, were 3.0 (95% CI, 1.7-5.3) for a genital hiatus size of 3 cm and 9.0 (95% CI, 5.5-14.8) for a genital hiatus size greater than or equal to 3.5 cm. Conclusions and Relevance Compared with spontaneous vaginal delivery, cesarean delivery was associated with significantly lower hazard for stress urinary incontinence, overactive bladder, and pelvic organ prolapse, while operative vaginal delivery was associated with significantly higher hazard of anal incontinence and pelvic organ prolapse. A larger genital hiatus was associated with increased risk of pelvic organ prolapse independent of delivery mode.

Background Obstetrical levator ani muscle avulsion is detected after 10%–30% of vaginal deliveries and is associated with pelvic organ prolapse later in life. However, the mechanism by which levator avulsion may contribute to prolapse is unknown. Objectives This study investigated the extent by which size of the levator hiatus and pelvic muscle weakness may explain the association between levator avulsion and pelvic organ prolapse. Study Design This was a supplementary study of a longitudinal cohort of parous women enrolled 5–10 years after first delivery and assessed annually for prolapse (defined as descent beyond the hymen) for up to 9 annual visits. For this substudy, vaginally parous participants were assessed for levator avulsion using 3-dimensional transperineal ultrasound. Ultrasound was performed at a median interval of 11 years from delivery. Ultrasound volumes also were used to measure levator hiatus area with Valsalva. Pelvic muscle strength was measured with perineometry. Women with and without pelvic organ prolapse were compared for levator avulsion, levator hiatus area, and pelvic muscle strength, using multivariable logistic regression yielding a measure of mediation. Bootstrap methods were used to calculate the confidence interval corresponding to the measure of mediation by hiatus area and pelvic muscle strength. Results Prolapse was identified in 109 of 429 (25%) and was significantly associated with levator avulsion (odds ratio, 4.17; 95% confidence interval, 2.28–7.31). Prolapse also was associated with levator hiatus area (odds ratio, 1.52 per 5 cm2; 95% confidence interval, 1.34–1.73) and inversely with muscle strength (odds ratio, 0.87 per 5 cm H2O; 95% confidence interval, 0.81–0.94). In a multivariable logistic model including levator avulsion, levator hiatus area, and strength, the association between levator avulsion and prolapse was substantially attenuated and indeed was no longer statistically significant (odds ratio, 1.75; 95% confidence interval, 0.91–3.39). Hiatus area and strength mediated 61% (95% confidence interval, 34%–106%) of the association between avulsion and prolapse. Furthermore, since the 95% confidence interval for this estimate contained 100%, it cannot be ruled out that the 2 markers fully mediate the effect of avulsion on prolapse. Conclusions The strong association between pelvic organ prolapse and levator avulsion can be explained to a large extent by a larger levator hiatus and weaker pelvic muscles after levator avulsion.

OBJECTIVE This study aimed to establish the extent to which care-seeking for urinary incontinence is a function of symptom bother; and to identify bother-score thresholds that predict care-seeking in the first 2 decades after delivery. METHODS In this longitudinal cohort, women were assessed annually for symptom bother related to stress urinary incontinence (SUI) and overactive bladder (OAB), as well as for recent episodes of care-seeking for urinary symptoms. Because the goal was to model care-seeking as a function of the woman's characteristics at her prior visit, women who completed 2 or more consecutive visits were included. The population was randomly divided into "training" (model development) and "testing" (model validation) sets. The predictive model was developed in the training set. For SUI and OAB bother scores, we identified thresholds to define statistically distinct probabilities of care-seeking. A multivariable model was created, including SUI and OAB bother categories as well as characteristics associated with care seeking at the P < 0.05 level. The resultant prediction model was then applied to the "testing set"; predicted and observed care-seeking frequencies were compared. RESULTS Care-seeking was strongly associated with SUI and OAB bother. We defined 3 categories for OAB score and 4 categories for SUI score. The resulting 12 risk categories were then collapsed into 5 distinct risk-groups. These groups accurately predicted care-seeking in the testing set (area under the receiver operating curve, 0.760; 95% confidence interval, 0.713-0.807). Inclusion of other risk factors did not improve the model. CONCLUSIONS Symptom bother is a strong determinant of care-seeking in the first 2 decades after delivery. These results define 5 ordinal categories that predict seeking care for urinary symptoms in a community population.

Using a lifespan model, this article presents new scientific findings regarding risk factors for pelvic floor disorders (PFDs), focusing on the role of childbirth in the development of single or multiple coexisting PFDs. Phase I of the model includes predisposing factors, such as genetic predisposition and race. Phase II includes inciting factors, such as obstetric events. Prolapse, urinary incontinence (UI), and fecal incontinence (FI) are more common among vaginally parous women, although the impact of vaginal delivery on risk of FI is less dramatic than prolapse and UI. Phase III includes intervening factors, such as age and obesity.

Background Pelvic floor disorders (including urinary and anal incontinence and pelvic organ prolapse) are associated with childbirth. Injury to the pelvic floor muscles during vaginal childbirth, such as avulsion of the levator ani muscle, is associated with weaker pelvic floor muscle strength. As weak pelvic floor muscle strength may be a modifiable risk factor for the later development of pelvic floor disorders, it is important to understand how pelvic floor muscle strength affects the course of pelvic floor disorders over time. Objective To investigate the association between pelvic floor muscle strength and the incidence of pelvic floor disorders, and to identify maternal and obstetrical characteristics that modify the association. Materials and Methods This is a longitudinal study investigating pelvic floor disorders after childbirth. Participants were recruited 5–10 years after their first delivery and were assessed for pelvic floor disorders annually for up to 9 years. Stress incontinence, overactive bladder, and anal incontinence were assessed at each annual visit using the Epidemiology of Prolapse and Incontinence Questionnaire. Pelvic organ prolapse was assessed on physical examination, and was defined as descent of the vaginal walls or cervix beyond the hymen during forceful Valsalva. The primary exposure of interest was pelvic floor muscle strength, defined as the peak pressure during a voluntary pelvic muscle contraction (measured with a perineometer). The relationship between pelvic floor muscle strength and the cumulative incidence (time to event) of each pelvic floor disorder was evaluated using lognormal models, stratified by vaginal vs cesarean delivery. The relative hazard for each pelvic floor disorder (among those women free of the disorder at enrollment and thus more than 5–10 years from first delivery), was estimated using semiparametric proportional hazard models as a function of delivery mode, pelvic floor muscle strength, and other covariates. Results Of 1143 participants, the median age was 40 (interquartile range, 36.6–43.7) years, and 73% were multiparous. On perineometry, women with at least 1 vaginal delivery were more likely to have a low peak pressure, defined as Conclusion After vaginal delivery, but not cesarean delivery, the cumulative incidence of pelvic organ prolapse, stress incontinence, and overactive bladder is associated with pelvic muscle strength, but the associations attenuate when adjusting for genital hiatus and body mass index.

OBJECTIVES With vaginal childbirth, 10% to 30% of women sustain levator ani muscle avulsion. The objective of this study was to estimate the cumulative incidence of prolapse and other pelvic floor disorders (PFDs), comparing vaginally parous women with and without levator avulsion. METHODS Parous women enrolled in a longitudinal study were assessed annually for PFDs with the Pelvic Organ Prolapse Quantification Examination (for prolapse) and the Epidemiology of Prolapse and Incontinence Questionnaire (for stress incontinence, overactive bladder, and anal incontinence). Three-dimensional transperineal ultrasound was used to identify levator avulsion. Women with and without levator avulsion after vaginal delivery were compared for the cumulative incidence of PFDs. Further analysis also stratified by forceps delivery. RESULTS At the time of assessment, 453 participants were 6 to 17 years from first delivery (median, 11 years). Levator avulsion was identified in 15% (66/453) and was more common among those who had undergone forceps-assisted delivery (P < 0.001). Levator avulsion was strongly associated with prolapse beyond the hymen (odds ratio, 2.7; 95% confidence interval, 1.3-5.7) and with symptoms of prolapse (odds ratio, 3.0; 95% confidence interval-1.2, 7.3). These associations persisted after controlling for forceps-assisted delivery. In contrast, the odds of stress incontinence, overactive bladder, and anal incontinence were marginally (but not significantly) increased among women with levator avulsion in this cohort. CONCLUSIONS Obstetric levator avulsion is strongly associated with pelvic organ prolapse. The relationship between levator avulsion and other PFDs may not be significant.

OBJECTIVES Obstetric levator avulsion may be an important risk factor for prolapse. This study compares the size of the levator hiatus, the width of the genital hiatus, and pelvic muscle strength between vaginally parous women with or without levator avulsion, 5 to 15 years after delivery. METHODS Parous women were assessed for levator ani avulsion, using 3-dimensional transperineal ultrasound. Women with and without levator ani avulsion were compared with respect to levator hiatus areas (measured on ultrasound), genital hiatus (measured on examination), and pelvic muscle strength (measured with perineometry). Further analysis also considered the association of forceps-assisted birth. RESULTS At a median interval of 11 years from first delivery, levator avulsion was identified in 15% (66/453). A history of forceps-assisted delivery was strongly associated with levator avulsion (45% vs 8%; P < 0.001). Levator avulsion was also associated with a larger levator hiatus area (+7.3 cm; 95% confidence interval [CI], 4.1-10.4, with Valsalva), wider genital hiatus (+0.6 cm; 95% CI, 0.3-0.9, with Valsalva), and poorer muscle strength (-14.5 cm H2O; 95% CI, -20.4 to -8.7, peak pressure). Among those with levator avulsion, forceps-assisted birth was associated with a marginal increase in levator hiatus size but not genital hiatus size or muscle strength. CONCLUSIONS Obstetric levator avulsion is associated with a larger levator hiatus, wider genital hiatus, and poorer pelvic muscle strength. Forceps-assisted birth is an important marker for levator avulsion but may not be an independent risk factor for the development of pelvic muscle weakness or changes in hiatus size in the absence of levator avulsion.

BACKGROUND: There is limited knowledge of the effects of time on change in pelvic floor muscle strength after childbirth. OBJECTIVE: The objectives of this study were to estimate the change in pelvic floor muscle strength in parous women over time and to identify maternal and obstetric characteristics associated with the rate of change. STUDY DESIGN: This is an institutional review board-approved prospective cohort study of parous women. Participants were recruited 5—10 years after first delivery and followed annually. Pelvic floor muscle strength (peak pressure with voluntary contraction) was measured at 2 annual visits approximately 4 years apart with the use of a perineometer. We calculated the change in peak pressures, which were standardized per 5-year interval. Linear regression was used to identify maternal and obstetric characteristics that are associated with the rate of change in peak pressure. The obstetric variable of greatest interest was delivery group. Participants were classified into 3 delivery groups (considering all deliveries for each multiparous woman). Delivery categories included cesarean only, at least 1 vaginal birth but no forceps-assisted deliveries, and at least 1 forceps-assisted vaginal birth. Statistical analysis was completed with statistical software. RESULTS: Five hundred forty-three participants completed 2 perineometer measurements with a median 4 years between measures (interquartile range, 3.1—4.8). At initial measurement, women were, on average, 40 years old and 8 years from first delivery. Initial strength was higher in participants who delivered all their children by cesarean (38.5 cm H(2)O) as compared with women with any vaginal non-forceps delivery (26.0 cm H(2)O) or vaginal forceps delivery (13.5 cm H(2)O; P

Objectives The aim of this prospective study was to investigate whether symptoms of incontinence and prolapse bias maternal recall of obstetrical events up to 10 years after delivery. Methods In this secondary analysis of data gathered from the Mothers' Outcomes After Delivery study, we compared obstetrical medical records with maternal recall of delivery events. We calculated the agreement between maternal recall and the medical record across 1821 deliveries from 1011 participants for events including macrosomia, mode of delivery, prolonged second of labor, episiotomy, spontaneous laceration, anal sphincter laceration, and operative delivery. Women with symptomatic pelvic floor disorders were identified through administration of the Epidemiology of Prolapse and Incontinence Questionnaire or a clinical history of therapy for a pelvic floor disorder. We determined whether agreement between maternal recall and the medical record differed for those with or without symptoms using the medical record as a criterion standard. Results Agreement between maternal recall and the medical record was excellent for macrosomia and forceps deliveries (κ > 0.8), fair to good for episiotomy (κ = 0.61) and anal sphincter laceration (κ = 0.57), and poor for spontaneous perineal laceration (κ = 0.41). Symptomatic pelvic floor disorders did not impact maternal recall of macrosomia, prolonged second stage, episiotomy, spontaneous laceration, or operative delivery. However, recall of anal sphincter lacerations was biased by symptoms of pelvic floor disorders. Specifically, symptomatic women were significantly more likely to report a history of anal sphincter laceration, regardless of whether a sphincter laceration was documented (P = 0.025). Conclusions Maternal recall of anal sphincter laceration may be biased by symptomatic pelvic floor disorders. In research based on maternal recall of obstetrical events, this could strengthen the apparent association between sphincter laceration and pelvic floor disorders.

Background Pelvic organ prolapse is more common among parous (vs nulliparous) women and also more common after vaginal (vs cesarean) birth. However, very little is known about how childbirth affects the course and progression of the genital hiatus across a woman’s life span. Objective The objective of the sttudy was to investigate the longitudinal, quantitative changes in pelvic organ support after childbirth, focusing on the impact of vaginal vs cesarean delivery. Study Design This was a prospective longitudinal cohort study in which parous women were recruited 5–10 years from first delivery and followed up annually. Using data from annual pelvic organ prolapse quantification examinations, we considered changes in vaginal support at the anterior vaginal wall (point Ba), the vaginal apex (point C), and the posterior wall (point Bp). In univariate and multivariable models, we compared pelvic organ support between women who had delivered at least 1 child vaginally vs those delivered exclusively by cesarean. Other covariates considered included race, age at first delivery, and the size of the genital hiatus. For models of support at Ba and Bp, we also considered the independent association with apical support. For women who delivered vaginally, we also considered forceps birth. Results A total of 1224 women participated for a total of 7055 woman-visits. In multivariable models, vaginal birth was associated with significantly worse support 5 years from first delivery. Also, women with at least 1 vaginal birth had more rapid worsening of support at point C. The width of the genital hiatus was a significant independent predictor of worse support 5 years from delivery as well as the rate of change over time. In models that controlled for the genital hiatus, the strength of the impact of vaginal birth was attenuated. Conclusion Vaginal birth was associated with worse support 5 years from first delivery and with more rapid deterioration in support at the apex. Above and beyond the impact of vaginal birth, the size of the genital hiatus may be an independent marker for those at greatest risk of prolapse progression.

AIMS To describe longitudinal changes in symptoms of overactive bladder (OAB) and stress urinary incontinence (SUI) among parous women.

BACKGROUND: Postpartum recovery from pelvic floor trauma associated with vaginal delivery may be impaired by the transient hypoestrogenic state associated with breastfeeding. OBJECTIVE: The aim of our study was to examine the association between exclusive breastfeeding and pelvic floor disorders one to two decades after the first vaginal delivery. We hypothesize that compared to women who did not breastfeed following vaginal delivery, women who breastfeed would have a higher proportion of PFDs, and those women who practiced sustained exclusive/unsupplemented breastfeeding would have the highest proportion. STUDY DESIGN: This is a secondary analysis of the Mothers’ Outcomes After Delivery study, a prospective cohort study of pelvic floor disorders after childbirth. Participants were recruited 5–10 years after their first delivery and followed annually for up to 9 years. This analysis focused on participants who experienced at least one vaginal delivery. Each participant completed a self-administered questionnaire regarding breastfeeding. Based on questionnaire responses, breastfeeding status was classified into three ordinal categories: “Unexposed” (did not breastfeed or breastfed

Pelvic muscle strength decreases after childbirth.,1–3 Moreover, several small studies of postpartum women have shown that pelvic muscle strength is lower after vaginal than after cesarean delivery.4–6 The influence of other aspects of childbirth has not been investigated. Also, the influence of childbirth on pelvic muscle function has not been studied beyond the immediate postpartum period. Pelvic muscle function is a potentially important outcome of childbirth, because muscle weakness is associated with pelvic floor disorders. For example, pelvic muscle strengthening is recommended to reduce urinary incontinence in the postpartum period and later in life.7 Also, cross-sectional studies suggest an association between urinary incontinence and pelvic muscle weakness,2,6,8 although anal incontinence does not appear to be associated with pelvic muscle weakness.9 Investigations of pelvic muscle strength and pelvic organ prolapse (POP) have reached conflicting conclusions.10–12 A computer simulation model13 predicts that pelvic muscle weakness would result in progressive uterovaginal prolapse. Although this prediction is intriguing, this model has not been validated in vivo. The current study was undertaken to estimate the effect of vaginal delivery and other obstetric exposures on pelvic muscle strength, measured 6–11 years after first delivery. In the setting of a longitudinal cohort study of maternal health after childbirth,14 we measured pelvic muscle strength among parous women. Our goal was to identify obstetric exposures associated with pelvic muscle strength. We also sought to investigate the relationship between pelvic muscle strength and pelvic floor disorders in this population 6–11 years after a woman’s first delivery.

Aim: The objective of this study was to identify maternal, obstetrical and reproductive factors associated with long-term changes in maternal weight after delivery. Materials & methods: Participants were enrolled in a longitudinal cohort study of maternal health 5–10 years after childbirth. Data were obtained from obstetrical records and a self-administered questionnaire. Weight at the time of first delivery (5–10 years prior) was obtained retrospectively and each woman's weight at the time of her first delivery was compared with her current weight. Results: Among 948 women, obesity was associated with race, parity, education, history of diabetes and history of cesarean at the time of first delivery. On average, the difference between weight at the time of first delivery and weight 5–10 years later was −11 kg (11 kg weight loss). In a multivariate model, black race and diabetes were associated with significantly less weight loss. Cesarean delivery, parity and breastfeeding were not associated with changes in maternal weight. Conclusion: Black women and those with a history of diabetes may be appropriate targets for interventions that promote a long-term healthy weight after childbirth.

Benign joint hypermobility syndrome may be a risk factor for pelvic floor disorders. It is unknown whether hypermobility impacts the progress of childbirth, a known risk factor for pelvic floor disorders. Our objective was to investigate the association between joint hypermobility syndrome, obstetrical outcomes, and pelvic floor disorders. Our hypotheses were: (1) women with joint hypermobility are less likely to experience operative delivery and prolonged second-stage labor; and (2) pelvic floor disorders are associated with benign hypermobility syndrome, controlling for obstetrical history.Joint hypermobility was measured in 587 parous women (participants in a longitudinal cohort study of pelvic floor disorders after childbirth). Their obstetrical histories were obtained from review of hospital records. Pelvic floor disorders were assessed using validated questionnaires and a structured examination for prolapse. Joint hypermobility and pelvic floor disorders were evaluated at enrollment (5-10 years after first delivery). We compared obstetrical outcomes and pelvic floor disorders between women with and without joint hypermobility, defined as a Beighton score ≥ 4.Hypermobility was diagnosed in 46 women (7.8 %) and was associated with decreased odds of cesarean after complete cervical dilation or operative vaginal delivery [odds ratio (OR)=0.51; 95 % confidence interval (CI):0.27-0.95]. Anal sphincter laceration was unlikely to occur in women with hypermobility (OR=0.19; 95 % CI 0.04-0.80). However, hypermobility was not associated with any pelvic floor disorder considered.Benign joint hypermobility syndrome may facilitate spontaneous vaginal birth but does not appear to be a risk factor for pelvic floor disorders in the first decade after childbirth.

Objective The objective of this study was to characterize changes in pelvic organ support and symptoms of prolapse over time and identify characteristics associated with worsening of support. Methods Participants were recruited based on the mode of delivery (cesarean vs vaginal delivery) of their first child. The Pelvic Organ Prolapse Quantification system was used to describe support at baseline and 12 to 18 months later. Symptoms were assessed using a validated questionnaire. Outcomes of interest included the proportion of women with a change in support greater than 1 cm at the anterior vaginal wall (Ba) or posterior vaginal wall (Bp) and a change in support greater than 2 cm at the apex (C). Characteristics associated with worsening of support were identified using 2-sided Fisher's exact test and multivariable logistic regression. Results Among 749 participants, 60% had delivered by cesarean delivery only. Worsening support at Ba, Bp, and C was observed in 8%, 2%, and 6%, respectively. Worsening at any point was observed in 110 women (15%). Women with prolapse symptoms at baseline were not more likely to experience worsening of support. In a multivariable model, age older than 40 years (odds ratio [OR], 1.64; 95% confidence interval [CI], 1.09-2.49), vaginal delivery (OR, 3.12; 95% CI, 1.38-7.07), and genital hiatus greater than or equal to 2 (OR, 2.36; 95% CI, 1.03-5.43) were all associated with worsening support in at least 1 compartment. Conclusions Over 12 to 18 months, characteristics most strongly associated with worsening of pelvic support include genital hiatus size, vaginal birth, and age.

OBJECTIVE: To investigate whether episiotomy, perineal laceration, and operative delivery are associated with pelvic floor disorders after vaginal childbirth. METHODS: This is a planned analysis of data for a cohort study of pelvic floor disorders. Participants who had experienced at least one vaginal birth were recruited 5–10 years after delivery of their first child. Obstetric exposures were classified by review of hospital records. At enrollment, pelvic floor outcomes, including stress incontinence, overactive bladder, anal incontinence, and prolapse symptoms were assessed with a validated questionnaire. Pelvic organ support was assessed using the Pelvic Organ Prolapse Quantification system. Logistic regression analysis was used to estimate the relative odds of each pelvic floor disorder by obstetric history, adjusting for relevant confounders. RESULTS: Of 449 participants, 71 (16%) had stress incontinence, 45 (10%) had overactive bladder, 56 (12%) had anal incontinence, 19 (4%) had prolapse symptoms, and 64 (14%) had prolapse to or beyond the hymen on examination. Forceps delivery increased the odds of each pelvic floor disorder considered, especially overactive bladder (odds ratio [OR] 2.92, 95% confidence interval [CI] 1.44–5.93), and prolapse (OR 1.95, 95% CI 1.03–3.70). Episiotomy was not associated with any of these pelvic floor disorders. In contrast, women with a history of more than one spontaneous perineal laceration were significantly more likely to have prolapse to or beyond the hymen (OR 2.34, 95% CI 1.13–4.86). Our multivariable results suggest that one additional woman would have development of prolapse for every eight women who experienced at least one forceps birth (compared with delivering all her children by spontaneous vaginal birth). CONCLUSION: Forceps deliveries and perineal lacerations, but not episiotomies, were associated with pelvic floor disorders 5–10 years after a first delivery.

Objective Given limitations in surgical educational resources, more efficient teaching methods are needed. We sought to evaluate 3 strategies for improving skills in subcuticular suturing—practice with an instructional video, practice with expert instructor supervision, and independent practice. Design Fifty-eight medical students volunteered for this research. Students viewed a video on subcuticular suturing then completed a pretest requiring closure of an incision in a plastic model. Students were randomized among 3 groups: practice with an instructional video (group A), practice with supervision by an expert instructor (group B), and independent practice (group C). After instruction, students completed a posttest, then a retention test 1 week later. Their performances were video recorded and evaluated using a validated scoring instrument composed of global and task-specific subscales. Results Performances measured using both subscales improved significantly from pretest to post-test only for group B. However, when comparing student performances between pretest and retention posttest, significant improvements on both subscales were seen only in group A. Conclusion These results suggest that practice with an instructional video is an effective method for acquiring skill in subcuticular suturing.

To investigate maternal characteristics associated with breastfeeding initiation and success. Women enrolled in the Mothers Outcomes After Delivery study reported breastfeeding practices 5-10 years after a first delivery. Women were classified as successful breastfeeding initiators, unsuccessful initiators, or non-initiators. For the first birth, demographic and obstetrical characteristics were compared across these three breastfeeding groups. For multiparous women, agreement in breastfeeding status between births was evaluated. Multivariate regression analysis was used to identify characteristics associated with non-initiation and unsuccessful breastfeeding across all births. Of 812 participants, 740 (91%) mothers tried to breastfeed their first child and 593 (73%) reported breastfeeding successfully. In a multivariate analysis, less educated women were less likely to initiate breastfeeding (odds ratio (OR) for non-initiation 1.97; 95% confidence interval (CI) 1.23, 3.14). There was a notable decrease in breastfeeding initiation with increasing birth order: compared to the first birth, the odds for non-initiation after a second delivery almost doubled (OR 1.83, 95% CI 1.42, 2.35) and the odds for non-initiation after a third delivery were further increased (OR 2.44, 95% CI 1.56, 3.82). Successful breastfeeding in a first pregnancy was a predictor of subsequent breastfeeding initiation and success. Specifically, women who did not attempt breastfeeding or who reported unsuccessful attempts to breastfeed at first birth were unlikely to initiate breastfeeding at later births. Cesarean delivery was not associated with breastfeeding initiation (OR 1.01; 95% CI 0.68, 1.48) or success (OR 1.33; 95% CI 0.92, 1.94). Breastfeeding practices after a first birth are a significant predictor of breastfeeding in subsequent births.
