Novel Evidence-Based Labor Induction Algorithm Associated with Increased Vaginal Delivery within 24 Hours.

OBJECTIVE: This study aimed to assess whether concordance with our proposed labor induction algorithm is associated with an increased rate of vaginal delivery within 24 hours. STUDY DESIGN: We conducted a retrospective review of 287 induction of labors (IOLs) at a single urban, tertiary, academic medical center which took place before we created an evidence-based IOL algorithm. We then compared the IOL course to the algorithm to assess for concordance and outcomes. Patients age 18 years or over with a singleton, cephalic pregnancy of 366/7 to 420/7 weeks' gestation were included. Patients were excluded with a Bishop's score >6, contraindication to misoprostol or cervical Foley catheter, major fetal anomalies, or intrauterine fetal death. Patients with 100% concordance were compared with <100% concordant patients, and patients with ≥80% concordance were compared with <80% concordant patients. Adjusted hazard ratios (AHRs) were calculated for rate of vaginal delivery within 24 hours, our primary outcome. Competing risk's analysis was conducted for concordant versus nonconcordant groups, using vaginal delivery as the outcome of interest, with cesarean delivery (CD) as a competing event. RESULTS: Patients with 100% concordance were more likely to have a vaginal delivery within 24 hours, n = 66 of 77 or 85.7% versus n = 120 of 210 or 57.1% (p < 0.0001), with an AHR of 2.72 (1.98, 3.75, p < 0.0001) after adjusting for delivery indication and scheduled status. Patients with 100% concordance also had shorter time from first intervention to delivery (11.9 vs. 19.4 hours). Patients with ≥80% concordance had a lower rate of CD (11/96, 11.5%) compared with those with <80% concordance (43/191 = 22.5%; p = 0.0238). There were no differences in neonatal outcomes assessed. CONCLUSION: Our IOL algorithm may offer an opportunity to standardize care, improve the rate of vaginal delivery within 24 hours, shorten time to delivery, and reduce the CD rate for patients undergoing IOL. KEY POINTS: · Studies on IOL have focused on individual steps. A labor induction algorithm allows for standardization.. · Algorithm concordance is associated with decreased time to delivery.. · Algorithm concordance is associated with decreased CD rate..

Characteristics and Outcomes of Pregnant Women with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in New York City: A Matched Cohort Study.

OBJECTIVE: The aim of this study was to examine the association between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and preterm birth, cesarean birth, and composite severe maternal morbidity by studying women with and without SARS-CoV-2 infection at the time of delivery hospitalization from similar residential catchment areas in New York City. STUDY DESIGN: This was a retrospective cohort study of pregnant women with laboratory-confirmed or laboratory-denied SARS-CoV-2 on nasopharyngeal swab under universal testing policies at the time of admission who gave birth between March 13 and May 15, 2020, at two New York City medical centers. Demographic and clinical data were collected and follow-up was completed on May 30, 2020. Groups were compared for the primary outcome and preterm birth, in adjusted (for age, race/ethnicity, nulliparity, body mass index) and unadjusted analyses. RESULTS: Among this age-matched cohort, 164 women were positive and 247 were negative for SARS-CoV-2. Of the positive group, 52.4% were asymptomatic and 1.2% had critical coronavirus disease 2019 (COVID-19). The groups did not differ by race and ethnicity, body mass index, or acute or chronic comorbidities. Women with SARS-CoV-2 were more likely to be publicly insured. Preterm birth, cesarean birth, and severe maternal morbidity did not differ between groups. Babies born to women with SARS-CoV-2 were more likely to have complications of prematurity or low birth weight (7.7 vs. 2%, p = 0.01). CONCLUSION: Preterm and cesarean birth did not differ between women with and without SARS-CoV-2 across disease severity in adjusted and unadjusted analysis among this cohort during the pandemic peak in New York City.

Pregnant women with severe or critical coronavirus disease 2019 have increased composite morbidity compared with nonpregnant matched controls.

BACKGROUND: In March 2020, as community spread of severe acute respiratory syndrome coronavirus 2 became increasingly prevalent, pregnant women seemed to be equally susceptible to developing coronavirus disease 2019. Although the disease course usually appears mild, severe and critical cases of coronavirus disease 2019 seem to lead to substantial morbidity, including intensive care unit admission with prolonged hospital stay, intubation, mechanical ventilation, and even death. Although there are recent reports regarding the impact of coronavirus disease 2019 on pregnancy, there is a lack of information regarding the severity of coronavirus disease 2019 in pregnant vs nonpregnant women. OBJECTIVE: We aimed to describe the outcomes of severe and critical cases of coronavirus disease 2019 in pregnant vs nonpregnant, reproductive-aged women. STUDY DESIGN: This is a multicenter, retrospective, case-control study of women with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 infection hospitalized with severe or critical coronavirus disease 2019 in 4 academic medical centers in New York City and 1 in Philadelphia between March 12, 2020, and May 5, 2020. The cases consisted of pregnant women admitted specifically for severe or critical coronavirus disease 2019 and not for obstetrical indications. The controls consisted of reproductive-aged, nonpregnant women admitted for severe or critical coronavirus disease 2019. The primary outcome was a composite morbidity that includes the following: death, a need for intubation, extracorporeal membrane oxygenation, noninvasive positive pressure ventilation, or a need for high-flow nasal cannula O2 supplementation. The secondary outcomes included intensive care unit admission, length of stay, a need for discharge to long-term acute care facilities, and discharge with a home O2 requirement. RESULTS: A total of 38 pregnant women with severe acute respiratory syndrome coronavirus 2 polymerase chain reaction-confirmed infections were admitted to 5 institutions specifically for coronavirus disease 2019, 29 (76.3%) meeting the criteria for severe disease status and 9 (23.7%) meeting the criteria for critical disease status. The mean age and body mass index were markedly higher in the nonpregnant control group. The nonpregnant cohort also had an increased frequency of preexisting medical comorbidities, including diabetes, hypertension, and coronary artery disease. The pregnant women were more likely to experience the primary outcome when compared with the nonpregnant control group (34.2% vs 14.9%; P=.03; adjusted odds ratio, 4.6; 95% confidence interval, 1.2-18.2). The pregnant patients experienced higher rates of intensive care unit admission (39.5% vs 17.0%; P<.01; adjusted odds ratio, 5.2; 95% confidence interval, 1.5-17.5). Among the pregnant women who underwent delivery, 72.7% occurred through cesarean delivery and the mean gestational age at delivery was 33.8±5.5 weeks in patients with severe disease status and 35±3.5 weeks in patients with critical coronavirus disease 2019 status. CONCLUSION: Pregnant women with severe and critical coronavirus disease 2019 are at an increased risk for certain morbidities when compared with nonpregnant controls. Despite the higher comorbidities of diabetes and hypertension in the nonpregnant controls, the pregnant cases were at an increased risk for composite morbidity, intubation, mechanical ventilation, and intensive care unit admission. These findings suggest that pregnancy may be associated with a worse outcome in women with severe and critical cases of coronavirus disease 2019. Our study suggests that similar to other viral infections such as severe acute respiratory syndrome coronavirus and Middle East respiratory syndrome coronavirus, pregnant women may be at risk for greater morbidity and disease severity.

Investigation of health inequities in maternal and neonatal outcomes of patients with placenta accreta spectrum: a multicenter study.

BACKGROUND: Placenta accreta spectrum is associated with significant maternal and neonatal morbidity and mortality. There is limited established data on healthcare inequities in the outcomes of patients with placenta accreta spectrum. OBJECTIVE: This study aimed to investigate health inequities in maternal and neonatal outcomes of pregnancies with placenta accreta spectrum. STUDY DESIGN: This multicentered retrospective cohort study included patients with a histopathological diagnosis of placenta accreta spectrum at 4 regional perinatal centers between January 1, 2013, and June 30, 2022. Maternal race and ethnicity were categorized as either Hispanic, non-Hispanic Black, non-Hispanic White, or Asian or Pacific Islander. The primary outcome was a composite adverse maternal outcome: transfusion of ≥4 units of packed red blood cells, vasopressor use, mechanical ventilation, bowel or bladder injury, or mortality. The secondary outcomes were a composite adverse neonatal outcome (Apgar score of <7 at 1 minute, morbidity, or mortality), gestational age at placenta accreta spectrum diagnosis, and planned delivery by a multidisciplinary team. Multivariable logistic regression was used to estimate the associations of race and ethnicity with maternal and neonatal outcomes. RESULTS: A total of 408 pregnancies with placenta accreta spectrum were included. In 218 patients (53.0%), the diagnosis of placenta accreta spectrum was made antenatally. Patients predominantly self-identified as non-Hispanic White (31.6%) or non-Hispanic Black (24.5%). After adjusting for institution, age, body mass index, income, and parity, there was no difference in composite adverse maternal outcomes among the racial and ethnic groups. Similarly, adverse neonatal outcomes, gestational age at prenatal diagnosis, rate of planned delivery by a multidisciplinary team, and cesarean hysterectomy were similar among groups. CONCLUSION: In our multicentered placenta accreta spectrum cohort, race and ethnicity were not associated with inequities in composite maternal or neonatal morbidity, timing of diagnosis, or planned multidisciplinary care. This study hypothesized that a comparable incidence of individual risk factors for perinatal morbidity and geographic proximity reduces potential inequities that may exist in a larger population.

Obstetric protocols in the setting of a pandemic.

The purpose of this article is to review key areas that should be considered and modified in our obstetric protocols, specifically: 1) Patient triage, 2) Labor and delivery unit policies, 3) Special considerations for personal protective equipment (PPE) needs in obstetrics, 4) Intrapartum management, and 5) Postpartum care.

Maternal Socioeconomic Factors and Racial/Ethnic Differences in Neonatal Anthropometry.

Disparities in birthweight by maternal race/ethnicity are commonly observed. It is unclear to what extent these disparities are correlates of individual socioeconomic factors. In a prospective cohort of 1645 low-risk singleton pregnancies included in the NICHD Fetal Growth Study (2009-2013), neonatal anthropometry was measured by trained personnel using a standard protocol. Socioeconomic characteristics included employment status, marital status, health insurance, annual income, and education. Separate adjusted generalized linear models were fit to both test the effect of race/ethnicity and the interaction of race/ethnicity and socioeconomic characteristics on neonatal anthropometry. Mean infant birthweight, length, head circumference, and abdominal circumference all differed by race/ethnicity (p < 0.001). We observed no statistically significant interactions between race/ethnicity and full-time employment/student status, marital status, insurance, or education in association with birthweight, neonatal exam weight, length, or head or abdominal circumference at examination. The interaction between income and race/ethnicity was significant only for abdominal circumference (p = 0.027), with no other significant interactions for other growth parameters, suggesting that racial/ethnic differences in neonatal anthropometry did not vary by individual socioeconomic factors in low-risk women. Our results do not preclude structural factors, such as lifetime exposure to poverty, as an explanation for racial/ethnic disparities.

Characteristics and Outcomes of 241 Births to Women With Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infection at Five New York City Medical Centers.

OBJECTIVE: To describe the characteristics and birth outcomes of women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection as community spread in New York City was detected in March 2020. METHODS: We performed a prospective cohort study of pregnant women with laboratory-confirmed SARS-CoV-2 infection who gave birth from March 13 to April 12, 2020, identified at five New York City medical centers. Demographic and clinical data from delivery hospitalization records were collected, and follow-up was completed on April 20, 2020. RESULTS: Among this cohort (241 women), using evolving criteria for testing, 61.4% of women were asymptomatic for coronavirus disease 2019 (COVID-19) at the time of admission. Throughout the delivery hospitalization, 26.5% of women met World Health Organization criteria for mild COVID-19, 26.1% for severe, and 5% for critical. Cesarean birth was the mode of delivery for 52.4% of women with severe and 91.7% with critical COVID-19. The singleton preterm birth rate was 14.6%. Admission to the intensive care unit was reported for 17 women (7.1%), and nine (3.7%) were intubated during their delivery hospitalization. There were no maternal deaths. Body mass index (BMI) 30 or higher was associated with COVID-19 severity (P=.001). Nearly all newborns tested negative for SARS-CoV-2 infection immediately after birth (97.5%). CONCLUSION: During the first month of the SARS-CoV-2 outbreak in New York City and with evolving testing criteria, most women with laboratory-confirmed infection admitted for delivery did not have symptoms of COVID-19. Almost one third of women who were asymptomatic on admission became symptomatic during their delivery hospitalization. Obesity was associated with COVID-19 severity. Disease severity was associated with higher rates of cesarean and preterm birth.

Seasonal, geographic, and antimicrobial resistance patterns in microbial keratitis: 4-year experience in eastern Pennsylvania.

PURPOSE: The aim of this study was to review the demographics, causative organisms, seasonal and geographic variation, and antimicrobial resistance patterns of microbial keratitis at our institution over a 4-year period. METHODS: Electronic medical records of all patients with microbial keratitis who underwent corneal culturing at a single institution in eastern Pennsylvania between January 1, 2009 and December 31, 2012 were reviewed. RESULTS: A total of 311 patients representing 323 instances of infectious keratitis were analyzed. The most frequently implicated organisms in contact lens-related infections were Pseudomonas aeruginosa for bacteria and Fusarium species for fungus, compared with Staphylococcus aureus and Candida species in non-contact lens-associated bacterial infections. Bacterial keratitis occurred most frequently in spring and least frequently in winter (P = 0.024). Patients who live in large fringe metro (suburban) areas accounted for the highest proportion of infectious keratitis cases. P. aeruginosa and methicillin-sensitive S. aureus isolates were highly susceptible to fluoroquinolones, whereas 32% of coagulase-negative staphylococcus isolates tested were resistant to moxifloxacin and gatifloxacin, and all methicillin-resistant S. aureus organisms tested were resistant to these 2 fluoroquinolones. No organisms tested were resistant to tobramycin, gentamicin, or vancomycin. No fungal infections tested were resistant to voriconazole. CONCLUSIONS: Most infectious keratitis occurred in nonwinter months and in patients from suburban counties. Although fluoroquinolones were effective against the most common bacteria, staphylococcal species exhibited a high rate of resistance, representing a therapeutic challenge given the increasing use of fluoroquinolones as first-line monotherapy. No organisms tested were resistant to tobramycin, gentamicin, vancomycin, or voriconazole.
