Quality Improvement Initiatives Lead to Reduction in Nulliparous Term Singleton Vertex Cesarean Delivery Rate.

BACKGROUND: The nulliparous term singleton vertex (NTSV) cesarean delivery rate has been recognized as a meaningful benchmark. Variation in the NTSV cesarean delivery rate among hospitals and providers suggests many hospitals may be able to safely improve their rates. The NTSV cesarean delivery rate at the authors' institution was higher than state and national averages. This study was conducted to determine the influence of a set of quality improvement interventions on the NTSV cesarean delivery rate. METHODS: From 2008 through 2015, at a single tertiary care academic medical center, a multi-strategy approach that included provider education, provider feedback, and implementation of new policies was used to target evidence-based and inferred factors that influence the NTSV cesarean delivery rate. Data on mode of delivery, maternal outcomes, and neonatal outcomes were collected from birth certificates and administrative claims data. The Cochran-Armitage test and linear regression were used to calculate the p-trend for categorical and continuous variables, respectively. RESULTS: More than 20,000 NTSV deliveries were analyzed, including more than 15,000 during the intervention period. The NTSV cesarean delivery rate declined from 35% to 21% over eight years. The total cesarean delivery rate declined as well. Increase in meconium aspiration syndrome and maternal transfusion were observed. CONCLUSION: Quality improvement initiatives can decrease the NTSV cesarean delivery rate. Any increased incidence of fetal or maternal complications associated with decreased NTSV cesarean delivery rate should be considered in the context of the risks and benefits of vaginal delivery compared to cesarean delivery.

Risk factors for Staphylococcus aureus postpartum breast abscess.

BACKGROUND: Staphylococcus aureus (SA) breast abscesses are a complication of the postpartum period. Risk factors for postpartum SA breast abscesses are poorly defined, and literature is conflicting. Whether risk factors for methicillin-resistant SA (MRSA) and methicillin-susceptible SA (MSSA) infections differ is unknown. We describe novel risk factors associated with postpartum breast abscesses and the changing epidemiology of this infection. METHODS: We conducted a cohort study with a nested case-control study (n = 216) involving all patients with culture-confirmed SA breast abscess among >30 000 deliveries at our academic tertiary care center from 2003 through 2010. Data were collected from hospital databases and through abstraction from medical records. All SA cases were compared with both nested controls and full cohort controls. A subanalysis was completed to determine whether risk factors for MSSA and MRSA breast abscess differ. Univariate analysis was completed using Student's t test, Wilcoxon rank-sum test, and analysis of variance, as appropriate. A multivariable stepwise logistic regression was used to determine final adjusted results for both the case-control and the cohort analyses. RESULTS: Fifty-four cases of culture-confirmed abscess were identified: 30 MRSA and 24 MSSA. Risk factors for postpartum SA breast abscess in multivariable analysis include in-hospital identification of a mother having difficulty breastfeeding (odds ratio, 5.00) and being a mother employed outside the home (odds ratio, 2.74). Risk factors did not differ between patients who developed MRSA and MSSA infections. CONCLUSIONS: MRSA is an increasingly important pathogen in postpartum women; risk factors for postpartum SA breast abscess have not changed with the advent of community-associated MRSA.

Timing of antibiotic administration and infectious morbidity following cesarean delivery: incorporating policy change into workflow.

PURPOSE: To evaluate the success of a multidisciplinary approach to policy change regarding timing of antibiotic administration for the prevention of surgical-site infection after cesarean delivery. METHODS: After review of the evidence, our multidisciplinary Obstetrics Leadership Committee decided to change policy on the timing of antibiotic prophylaxis for cesarean delivery. Using a combination of meetings, email communications, and local champions, 100% compliance with the new policy was achieved in 5 weeks. The effect of this policy change was investigated through a prospective cohort study of consecutive patients undergoing cesarean delivery at one institution from January 2009 through May 2009. Approximately halfway through the study period our department implemented a practice change that required antibiotic administration before skin incision rather than after clamping the umbilical cord. We compared the incidence of surgical-site infection, including endometritis, cellulitis, and total infectious morbidity, among women who received antibiotics before skin incision to those who received antibiotics after umbilical cord clamp. RESULTS: There were 533 consecutive women who underwent cesarean delivery during the study period. Two hundred forty (45.0%) women received antibiotics after cord clamping, and 285 (53.5%) women received antibiotics before skin incision; timing could not be determined for 8 (1.5%) women. Within 5 weeks of the policy change, 100% of the women undergoing cesarean delivery received perioperative prophylactic antibiotics before skin incision. The incidence of infectious morbidity fell from 5.4 to 2.5% when antibiotics were given before skin incision. Compared to the administration of antibiotics before skin incision, receiving antibiotics after cord clamp yielded a crude relative risk (RR) of 2.21 (95% CI 0.89-5.44) for total infectious morbidity and 3.56 (95% CI 0.73-17.49) for endometritis. Although not statistically significant, there was an increased risk of cellulitis (RR 1.66; 95% CI 0.53-5.17) when antibiotics were administered after cord clamping. CONCLUSIONS: A multidisciplinary approach was successful in achieving 100% adherence to our institution's policy change regarding timing of prophylactic antibiotics. This approach was necessary in order to incorporate this type of change into the labor and delivery workflow and may serve as a paradigm for success in implementing labor and delivery quality improvement projects. In addition, administration of prophylactic antibiotics before skin incision resulted in fewer surgical-site infections following cesarean delivery. As the clinical and economic impact of surgical-site infections is considerable, the once common practice of administering antibiotics after cord clamping should be avoided.

Antepartum fibrinogen concentration as a predictor of bleeding complications.

OBJECTIVE: The objective of this study was to examine the predictive value of fibrinogen concentration for bleeding complications among women presenting for delivery and for whom a fibrinogen level was measured before delivery. STUDY DESIGN: This was a nested case-control study using a cohort of all women who delivered at our institution from October 2001 to July 2016 and in whom a fibrinogen concentration was obtained within 48 hours before delivery. We identified all cases that had one or more of the following events: (1) postpartum hemorrhage; (2) postpartum hysterectomy; (3) transfusion of select blood products; or (4) a ≥ 33% decrease in hematocrit from the first hematocrit measured during the hospital stay to any subsequent hematocrit value drawn either simultaneously with or following the fibrinogen concentration measurement. We included the first case or control delivery for a given woman. Controls were the next one or two consecutive deliveries without a bleeding complication and matched for number of fetuses. We used logistic regression to calculate the odds ratio and 95% confidence intervals and calculated the area under the receiver operating characteristic curve. RESULTS: We identified 424 cases and 801 controls. The mean predelivery fibrinogen concentration was significantly lower in cases (425 ± 170 mg/dL) than controls (523 ± 122 ng/mL) for all case types combined (p < .001) and for each case type individually (all p < .001). For every 100-mg/dL decrease in fibrinogen, the odds of a bleeding complication increased 1.63 times (95% confidence interval: 1.48-1.80). However, the area under the receiver operating characteristic curve was poor (0.69; 95% confidence interval: 0.65-0.72). Below 300 mg/dL there were 104 (24.5%) cases and 31 (3.9%) controls, yielding high specificity (96.1%) but extremely low sensitivity (24.5%). We could not identify a cutoff value that yielded acceptable values of both sensitivity and specificity. CONCLUSIONS: Antepartum fibrinogen concentration was significantly lower among women who developed bleeding complications, though these differences may not be large enough to provide clinically meaningful critical values. Nevertheless, a higher threshold for the critical value during pregnancy should be considered.

A multidisciplinary telemedicine model for management of coronavirus disease 2019 (COVID-19) in obstetrical patients.

Background: The COVID-19 pandemic caused by the SARS-CoV-2 has increased the demand for inpatient healthcare resources; however, approximately 80% of patients with COVID-19 have a mild clinical presentation and can be managed at home. Objective: This study aimed to describe the feasibility and clinical and process outcomes associated with a multidisciplinary telemedicine surveillance model to triage and manage obstetrical patients with known exposures and symptoms of COVID-19. Study Design: We implemented a multidisciplinary telemedicine surveillance model with obstetrical physicians and nurses to standardize ambulatory care for obstetrical patients with confirmed or suspected COVID-19 based on the symptoms or exposures at an urban academic tertiary care center with multiple hospital-affiliated and community-based practices. All pregnant or postpartum patients with COVID-19 symptoms, exposures, or hospitalization were eligible for inclusion in the program. Patients were assessed by means of regular nursing phone calls and were managed according to illness severity. Patient characteristics and clinical and process outcomes were abstracted from the electronic medical record. Results: A total of 135 patients were enrolled in the multidisciplinary telemedicine model from March 17 to April 19, 2020, of whom 130 were pregnant and 5 were recently postpartum. In this study, 116 of 135 patients (86%) were managed solely in the outpatient setting and did not require an in-person evaluation; 9 patients were ultimately admitted after ambulatory or urgent evaluations, and 10 patients were observed after hospital discharge. Although only 50% of the patients were tested secondary to limitations in ambulatory testing, 1 in 3 of those patients received positive results for SARS-CoV-2 (N=22, 16% of entire cohort). Patients were enrolled in the telemedicine model for a median of 7 days (interquartile range, 4-8) and averaged 1 phone call daily, resulting in 891 nursing calls and 20 physician calls over 1 month. Conclusion: A multidisciplinary telemedicine surveillance model for outpatient management of obstetrical patients with COVID-19 symptoms and exposures is feasible and resulted in rates of ambulatory management similar to those seen in nonpregnant patients. A centralized model for telemedicine surveillance of obstetrical patients with COVID-19 symptoms may preserve inpatient resources and prevent avoidable staff and patient exposures, particularly in centers with multiple ambulatory practice settings.

Association Between Labor and Delivery Unit Census and Delays in Patient Management: Findings From a Computer Simulation Module.

OBJECTIVE: To demonstrate the association between increases in labor and delivery unit census and delays in patient care decisions using a computer simulation module. METHODS: This was an observational cohort study of labor and delivery unit nurse managers. We developed a computer module that simulates the physical layout and clinical activity of the labor and delivery unit at our tertiary care academic medical center, in which players act as clinical managers in dynamically allocating nursing staff and beds as patients arrive, progress in labor, and undergo procedures. We exposed nurse managers to variation in patient census and measured the delays in resource decisions over the course of a simulated shift. We used mixed logistic and linear regression models to analyze the associations between patient census and delays in patient care. RESULTS: Thirteen nurse managers participated in the study and completed 17 12-hour shifts, or 204 simulated hours of decision-making. All participants reported the simulation module reflected their real-life experiences at least somewhat well. We observed 1.47-increased odds (95% CI 1.18-1.82) of recommending a patient ambulate in early labor for every additional patient on the labor and delivery unit. For every additional patient on the labor and delivery unit, there was a 15.9-minute delay between delivery and transfer to the postpartum unit (95% CI 2.4-29.3). For every additional patient in the waiting room, we observed a 33.3-minute delay in the time patients spent in the waiting room (95% CI 23.2-43.5) and a 14.3-minute delay in moving a patient in need of a cesarean delivery to the operating room (95% CI 2.8-25.8). CONCLUSION: Increasing labor and delivery unit census is associated with patient care delays in a computer simulation. Computer simulation is a feasible and valid method of demonstrating the sensitivity of care decisions to shifts in patient volume.

NICU Admissions After a Policy to Eliminate Elective Early Term Deliveries Before 39 Weeks' Gestation.

BACKGROUND AND OBJECTIVES: Early term infants (37-<39 weeks' gestation) are at higher risk of adverse outcomes than term infants (39-<41 weeks' gestation). We hypothesized that a policy to eliminate elective, early term deliveries would result in fewer NICU admissions and shorter lengths of stay among infants born ≥37 weeks. METHODS: This was a retrospective cohort study of singleton infants born ≥37 weeks at a tertiary medical center from 2004 to 2015 (preperiod: 2004-2008; postperiod: 2010-2015; washout period: 2009). We compared the incidence of early term delivery, NICU admissions (short: ≥4-<24 hours, long: ≥24 hours), NICU diagnoses, and stillbirths in both periods. We used modified Poisson regression to calculate adjusted risk ratios. RESULTS: There were 20 708 and 24 897 singleton infants born ≥37 weeks in the pre- and postperiod, respectively. The proportion of early term infants decreased from 32.5% to 25.7% (P < .0001). NICU admissions decreased nonsignificantly (9.2% to 8.8%; P = .22), with a significant reduction in short NICU stays (5.4% to 4.6%; adjusted risk ratio: 0.85 [95% confidence interval: 0.79-0.93]). Long NICU stays increased slightly (3.8% to 4.2%), a result that was nullified by adjusting for neonatal hypoglycemia. A nonsignificant increase in the incidence of stillbirths ≥37 to <40 weeks was present in the postperiod (7.5 to 10 per 10 000 births; P = .46). CONCLUSIONS: Reducing early term deliveries was associated with fewer short NICU stays, suggesting that efforts to discourage early term deliveries in uncomplicated pregnancies may minimize mother-infant separation in the newborn period.

Diabetes, Glycemic Control, and Urinary Incontinence in Women.

OBJECTIVES: To estimate the association between urinary incontinence and glycemic control in women ages 20 to 85 years. METHODS: We included 7270 women from the 2005 to 2010 National Health and Nutrition Examination Survey, stratified into three groups of glycemic control defined by hemoglobin A1c (HbA1c): (i) those below the diagnostic threshold (HbA1c < 6.5%), (ii) those with relatively controlled diabetes (HbA1c, 6.5-8.5%), and (iii) those with poorly controlled diabetes (HbA1c > 8.5%) to allow for a different relationship between glycemic control and urinary incontinence within each group. The primary outcomes were the presence of any, only stress, only urgency, and mixed urinary incontinence. We calculated adjusted risk ratios using Poisson regressions with robust variance estimates. RESULTS: The survey-weighted prevalence was 52.9% for any, 27.2% for only stress, 9.9% for only urgency, and 15.8% for mixed urinary incontinence. Among women with relatively controlled diabetes, each one-unit increase in HbA1c was associated with a 13% (95% confidence interval, 1.03-1.25) increase for any urinary incontinence and a 34% (95% confidence interval, 1.06-1.69) increase in risk for only stress incontinence but was not significantly associated with only urgency and mixed incontinence. Other risk factors included body mass index, hormone replacement therapy, smoking, and physical activity. CONCLUSIONS: Worsening glycemic control is associated with an increased risk for stress incontinence for women with relatively controlled diabetes. For those either below the diagnostic threshold or with poorly controlled diabetes, the risk may be driven by other factors. Further prospective investigation of HbA1c as a modifiable risk factor may motivate measures to improve continence in women with diabetes.

Lessons from Google and Apple: creating an open workplace in an academic medical department to foster innovation and collaboration.

PROBLEM: An expanding obstetrics-gynecology department at an academic medical center was faced with too little physical space to accommodate its staff, including trainees, attending physicians, researchers, scientists, administrative leadership, nurses, physician assistants, and scheduling/phone staff. Staff also felt that the current use of space was not ideal for collaboration and innovation. APPROACH: In 2011, the department collected data on space use, using a neutral surveyor and a standardized data collection tool. Using these data, architects and facilities managers met with the department to develop a floor plan proposal for a new use of the space. Site visits, departmental meetings, literature reviews, and space mock-ups complemented the decision process. The final architectural plan was developed using an iterative process that included all disciplines within the department. OUTCOMES: The redesigned workspace accommodates more staff in a modernized, open, egalitarian setup. The authors' informal observations suggest that the physical proximity created by the new workspace has facilitated timely and civil cross-discipline communication and improvements in team-oriented behavior, both of which are important contributors to safe patient care. NEXT STEPS: This innovation is generalizable and may lead other academic departments to make similar changes. In the future, the authors plan to measure the use of the space and to relate that to outcomes, including clinical (coordination of care/patient satisfaction), administrative (absenteeism/attrition), research (grant volume), and efficiency and cost measures.

Health and economic burden of post-partum Staphylococcus aureus breast abscess.

OBJECTIVES: To determine the health and economic burdens of post-partum Staphylococcus aureus breast abscess. STUDY DESIGN: We conducted a matched cohort study (N = 216) in a population of pregnant women (N = 32,770) who delivered at our center during the study period from 10/1/03-9/30/10. Data were extracted from hospital databases, or via chart review if unavailable electronically. We compared cases of S. aureus breast abscess to controls matched by delivery date to compare health services utilization and mean attributable medical costs in 2012 United States dollars using Medicare and hospital-based estimates. We also evaluated whether resource utilization and health care costs differed between cases with methicillin-resistant and -susceptible S. aureus isolates. RESULTS: Fifty-four cases of culture-confirmed post-partum S. aureus breast abscess were identified. Breastfeeding cessation (41%), milk fistula (11.1%) and hospital readmission (50%) occurred frequently among case patients. Breast abscess case patients had high rates of health services utilization compared to controls, including high rates of imaging and drainage procedures. The mean attributable cost of post-partum S. aureus breast abscess ranged from $2,340-$4,012, depending on the methods and data sources used. Mean attributable costs were not significantly higher among methicillin-resistant vs. -susceptible S. aureus cases. CONCLUSIONS: Post-partum S. aureus breast abscess is associated with worse health and economic outcomes for women and their infants, including high rates of breastfeeding cessation. Future study is needed to determine the optimal treatment and prevention of these infections.

Assessment of long-term knowledge retention following single-day simulation training for uncommon but critical obstetrical events.

OBJECTIVE: The objectives were to determine (i) whether simulation training results in short-term and long-term improvement in the management of uncommon but critical obstetrical events and (ii) to determine whether there was additional benefit from annual exposure to the workshop. METHODS: Physicians completed a pretest to measure knowledge and confidence in the management of eclampsia, shoulder dystocia, postpartum hemorrhage and vacuum-assisted vaginal delivery. They then attended a simulation workshop and immediately completed a posttest. Residents completed the same posttests 4 and 12 months later, and attending physicians completed the posttest at 12 months. Physicians participated in the same simulation workshop 1 year later and then completed a final posttest. Scores were compared using paired t-tests. RESULTS: Physicians demonstrated improved knowledge and comfort immediately after simulation. Residents maintained this improvement at 1 year. Attending physicians remained more comfortable managing these scenarios up to 1 year later; however, knowledge retention diminished with time. Repeating the simulation after 1 year brought additional improvement to physicians. CONCLUSION: Simulation training can result in short-term and contribute to long-term improvement in objective measures of knowledge and comfort level in managing uncommon but critical obstetrical events. Repeat exposure to simulation training after 1 year can yield additional benefits.

Documentation improvements following multidisciplinary educational program on electronic fetal heart rate tracings.

OBJECTIVE: To measure the effectiveness of a multifaceted, multidisciplinary, evidence-based educational program designed to achieve compliance with the National Institute of Child Health and Human Development (NICHD) definitions and three-tier system for electronic fetal heart rate (FHR) monitoring. METHODS: This prospective study began with a literature review focusing on creating change within complex systems. Evidence-based elements of program development and implementation were incorporated to promote the adoption of the NICHD guidelines for electronic FHR monitoring. A systematic, stratified random sample of charts was reviewed to evaluate compliance with the NICHD recommendations prior to and following program initiation. RESULTS: Compliance rates for documentation of all components of a FHR tracing and a category in SOAP notes increased from less than 1% to 90%. Of the remaining charts, following program implementation, 70% had all components of the FHR tracing documented. Following the educational intervention, only 1% of SOAP notes lacked a category and at least one component of FHR tracing compared to 39% prior to the program. CONCLUSIONS: Incorporating evidence-based strategies for systemic change is an important step in program development in obstetrics. A multifaceted, multi-disciplinary program with frequent audits and feedback can yield high compliance in adoption of guidelines and result in practice change.
