The Impact of Telehealth on Obstetrical Outcomes during the COVID-19 Pandemic.

OBJECTIVE: Nationwide, obstetric clinics modified prenatal care to include telehealth visits in response to the coronavirus disease 2019 (COVID-19) pandemic, enabling the opportunity to investigate its impact on patient outcomes. We hypothesized that use of prenatal telehealth visits would increase the number of prenatal visits, decrease the frequency of urgent triage/emergency department (ED) visits, and improve perinatal outcomes. This study aimed to determine the impact of telehealth on number of obstetric prenatal visits and urgent triage/ED visits amidst the COVID-19 pandemic. STUDY DESIGN: This is a retrospective cohort of patients from a federally qualified health center in central Texas. Patients with a singleton gestation who delivered after 32 weeks were included. Comparison groups were made between those patients who delivered between May 2020 and December 2020 (presumed modified prenatal visit schedule with in-person and telehealth) and those patients delivering between June 2019 and February 2020 (the traditional care model with in-person visits only). Multivariable linear and logistic regression models were used to estimate differences in the number of prenatal visits and unscheduled triage/ED visits. RESULTS: A total of 1,654 patients were identified with 801 (48.4%) patients undergoing modified prenatal care and 853 (51.6%) patients receiving traditional care during the study period. No significant differences were seen in overall prenatal attendance or triage/ED presentations. However, when stratified by parity, multiparous patients undergoing modified prenatal care were less likely to experience an urgent triage/ED presentation (8.7 vs. 12.7%; odds ratio, 1.69; 95% confidence interval, 1.10-2.61). CONCLUSION: When compared with a traditional prenatal visitation cohort prepandemic, patients who received modified telehealth prenatal care during the COVID-19 pandemic had similar prenatal attendance and unscheduled emergency presentations. However, multiparous patients experienced a decreased rate of unscheduled emergency presentations. Supplementing prenatal care with telehealth may provide overall comparable prenatal care delivery. KEY POINTS: · Use of telehealth has the potential to improve prenatal care.. · The COVID-19 pandemic allowed for comparison to traditional prenatal care.. · Multiparous patients had a decreased frequency of ED visits.. · Similar prenatal attendance was seen between both prenatal models..

Impact of household income and Special Supplemental Nutritional Program for Women, Infants, and Children on feeding decisions for infants in the United States.

BACKGROUND: Despite the known benefits of breastfeeding to infants and mothers, previous studies have demonstrated that underserved women are less likely to exclusively breastfeed. Existing studies on the impact of Special Supplemental Nutritional Program for Women, Infants, and Children enrollment on feeding decisions for infants have conflicting results with low-quality data and metrics. OBJECTIVE: This study aimed to examine infant feeding trends nationally in the first week postpartum over a 10-year period, comparing breastfeeding rates for primiparous women with low income who used Special Supplemental Nutritional Program for Women, Infants, and Children resources with those women who did not enroll. We hypothesized that although the Special Supplemental Nutritional Program for Women, Infants, and Children is an important resource for new mothers, free formula associated with enrollment in the Special Supplemental Nutritional Program for Women, Infants, and Children may disincentivize women to exclusively breastfeed. STUDY DESIGN: This was a retrospective cohort study of primiparous women with singleton gestations who gave birth at term and who responded to the Centers for Disease Control and Prevention Pregnancy Risk Assessment Monitoring System between 2009 and 2018. Data were extracted from phases 6, 7, and 8 of the survey. Women with low income were defined as those with a reported annual household income of $35,000 or less. The primary outcome was exclusive breastfeeding after 1 week postpartum. Secondary outcomes included ever breastfeeding, any breastfeeding after 1 week postpartum, and introduction of other liquids within 1 week postpartum. Multivariable logistic regression was used to refine risk estimates with adjustment for mode of delivery, household size, education level, insurance status, diabetes, hypertension, race, age, and BMI. RESULTS: Among the 42,778 women with low income who were identified, 29,289 (68%) of these women reported receiving Special Supplemental Nutritional Program for Women, Infants, and Children resources. There was no significant difference in the rates of exclusive breastfeeding after 1 week postpartum between those enrolled in the Special Supplemental Nutritional Program for Women, Infants, and Children and those not enrolled (adjusted risk ratio, 1.04; 95% confidence interval, 1.00-1.07; P=.10). However, those enrolled were less likely to ever breastfeed (adjusted risk ratio, 0.95; 95% confidence interval, 0.94-0.95; P<.01) and were more likely to introduce other liquids within 1 week postpartum (adjusted risk ratio, 1.16; 95% confidence interval, 1.11-1.21; P<.01). CONCLUSION: Although exclusive breastfeeding rates after 1 week postpartum were similar, women enrolled in the Special Supplemental Nutritional Program for Women, Infants, and Children were significantly less likely to ever breastfeed and more likely to introduce formula within the first week postpartum. This suggests that Special Supplemental Nutritional Program for Women, Infants, and Children enrollment may impact the decision to initiate breastfeeding and may represent an important window to test future interventions.

Women with preterm birth have a distinct cervicovaginal metabolome.

OBJECTIVE: Metabolomics has the potential to reveal novel pathways involved in the pathogenesis of preterm birth (PTB). The objective of this study was to investigate whether the cervicovaginal (CV) metabolome was different in asymptomatic women destined to have a PTB compared with term birth. STUDY DESIGN: A nested case-control study was performed using CV fluid collected from a larger prospective cohort. The CV fluid was collected between 20-24 weeks (V1) and 24-28 weeks (V2). The metabolome was compared between women with a spontaneous PTB (n = 10) to women who delivered at term (n = 10). Samples were extracted and prepared for analysis using a standard extraction solvent method. Global biochemical profiles were determined using gas chromatography/mass spectrometry and ultra-performance liquid chromatography/tandem mass spectrometry. An ANOVA was used to detect differences in biochemical compounds between the groups. A false discovery rate was estimated to account for multiple comparisons. RESULTS: A total of 313 biochemicals were identified in CV fluid. Eighty-two biochemicals were different in the CV fluid at V1 in those destined to have a PTB compared with term birth, whereas 48 were different at V2. Amino acid, carbohydrate, and peptide metabolites were distinct between women with and without PTB. CONCLUSION: These data suggest that the CV space is metabolically active during pregnancy. Changes in the CV metabolome may be observed weeks, if not months, prior to any clinical symptoms. Understanding the CV metabolome may hold promise for unraveling the pathogenesis of PTB and may provide novel biomarkers to identify women most at risk.

Global health training in US obstetrics and gynaecology residency programmes: perspectives of students, residents and programme directors.

BACKGROUND: Benefits of exposure to global health training during medical education are well documented and residents' demand for this training is increasing. Despite this, it is offered by few US obstetrics and gynaecology (OBGYN) residency training programmes. OBJECTIVES: To evaluate interest, perceived importance, predictors of global health interest and barriers to offering global health training among prospective OBGYN residents, current OBGYN residents and US OGBYN residency directors. METHODS: We designed two questionnaires using Likert scale questions to assess perceived importance of global health training. The first was distributed to current and prospective OBGYN residents interviewing at a US residency programme during 2012-2013. The second questionnaire distributed to US OBGYN programme directors assessed for existing global health programmes and global health training barriers. A composite Global Health Interest/Importance score was tabulated from the Likert scores. Multivariable linear regression was performed to assess for predictors of Global Health Interest/Importance. RESULTS: A total of 159 trainees (77%; 129 prospective OBGYN residents and 30 residents) and 69 (28%) programme directors completed the questionnaires. Median Global Health Interest/Importance score was 7 (IQR 4-9). Prior volunteer experience was predictive of a 5-point increase in Global Health Interest/Importance score (95% CI -0.19 to 9.85; p=0.02). The most commonly cited barriers were cost and time. CONCLUSION: Interest and perceived importance of global health training in US OBGYN residency programmes is evident among trainees and programme directors; however, significant financial and time barriers prevent many programmes from offering opportunities to their trainees. Prior volunteer experience predicts global health interest.

Using a prenatal electronic medical record to improve documentation within an inner-city healthcare network.

OBJECTIVE: To study the impact of a prenatal electronic medical record (EMR) on the adequacy of documentation. STUDY DESIGN: The authors reviewed paper prenatal records (historical control arm and contemporaneous control arm), and prenatal EMRs (study arm). A prenatal quality index (PQI) was developed to assess adequacy of documentation; the prenatal record was assigned a score (range, -1 to 2 for each element, maximum score = 30). A PQI raw score and PQI ratio-that controlled for which elements of care were indicated for a patient-were calculated and compared between the study arm versus historical control arm and then the study arm versus contemporaneous control arm. RESULTS: The median PQI raw score was significantly lower in the study arm compared with historical control arm; however, the PQI ratios were similar between these groups. The PQI raw score was similar in both the study arm and contemporaneous control arm; however the PQI ratio was significantly higher in the study arm when compared with the contemporaneous control arm. CONCLUSION: Implementation of this prenatal EMR did not have a significant impact on completeness of documentation when compared with a standardized paper prenatal record. Adequacy of documentation seems to be related to the type of practice.

Association of bactericidal activity of genital tract secretions with Escherichia coli colonization in pregnancy.

OBJECTIVE: Genital tract secretions exhibit bactericidal activity against Escherichia coli. We hypothesized that this defense may be modulated during pregnancy. STUDY DESIGN: Secretions were collected by vaginal swab from 70 pregnant women (35-37 weeks' gestation) and 35 nonpregnant controls. We mixed E coli with swab eluants or control buffer and colonies enumerated to measure bactericidal activity. Cytokines, chemokines, and antimicrobial peptides were quantified by multiplex or enzyme-linked immunosorbent assay. RESULTS: Pregnant women had significantly greater bactericidal activity, higher concentrations of proinflammatory cytokines, and lower levels of beta defensins compared to controls. Seven (10%) pregnant and 8 (23%) nonpregnant women were vaginally colonized with E coli; colonization was inversely associated with bactericidal activity. CONCLUSION: The soluble mucosal immune environment is altered in pregnancy. We speculate that the observed changes may protect against colonization and ascending infection and could provide a biomarker to identify pregnant women at risk for infectious complications including preterm birth.

Implementation of a universal cervical length screening program: identifying factors associated with decline rates.

PURPOSE: Cervical length (CL) measurement is now accepted as a screening strategy for identifying women at risk for preterm birth (PTB). However, patient acceptability may limit its implementation. Our objective was to identify characteristics associated with women who decline this screening. MATERIALS AND METHODS: This is a secondary analysis of a prospective cohort study of women offered UCL screening from January 2012 to June 2012. Women with a singleton gestation 18 0/7-23 6/7 weeks at the time of anatomy scan were included. Trained sonographers were instructed to perform UCL screening on all eligible patients using an "opt-out" approach. Chi square statistics and Wilcoxon rank sum tests were used to compare categorical and continuous data, where appropriate. Logistic regression was used to calculate odds ratio for factors associated with declining UCL screening Results: 1348 women were offered CL screening; 131 (9.7%) declined. Overall, multiparous women were more than twice as likely to decline UCL screening compared to primiparous women [OR 2.4 (1.6-3.8)]. Patient acceptance of screening was significantly dependent on the sonographer (p < .05). CONCLUSION: Multiparous women are less likely to accept this strategy of PTB prevention. A standardized counseling approach may improve patient acceptance and mitigate variability in acceptance rates observed amongst sonographers.

Activity of Genital Tract Secretions and Synthetic Antimicrobial Peptides against Group B Streptococcus.

PROBLEM: Genital tract secretions inhibit Escherichia coli (E. coli) through antimicrobial peptides (AMP) secreted by the host and vaginal microbiota. However, there are limited data against group B Streptococcus (GBS). METHOD OF STUDY: Group B Streptococcus were incubated with cervico-vaginal lavage (CVL) samples from healthy non-pregnant women (n = 12) or synthetic AMP and monitored for bacterial growth using a turbidimetric approach. E. coli inhibitory activity was determined by a colony-forming unit assay. RESULTS: None of the CVL samples inhibited GBS. The human neutrophil peptide-1 and human defensin 5 inhibited GBS growth by ≥80% at concentrations ≥20 µg/mL and ≥50 µg/mL, respectively, while human beta-defensin 2 and LL-37 did not inhibit at highest concentration tested (100 µg/mL). In contrast, all AMP inhibited E. coli. CONCLUSIONS: Antimicrobial peptides may protect against E. coli colonization but have more limited activity against GBS. Future studies will focus on augmenting host defense with specific AMP to prevent genitourinary infection with these pathogenic organisms.

Lactobacillus crispatus dominant vaginal microbiome is associated with inhibitory activity of female genital tract secretions against Escherichia coli.

OBJECTIVE: Female genital tract secretions inhibit E. coli ex vivo and the activity may prevent colonization and provide a biomarker of a healthy microbiome. We hypothesized that high E. coli inhibitory activity would be associated with a Lactobacillus crispatus and/or jensenii dominant microbiome and differ from that of women with low inhibitory activity. STUDY DESIGN: Vaginal swab cell pellets from 20 samples previously obtained in a cross-sectional study of near-term pregnant and non-pregnant healthy women were selected based on having high (>90% inhibition) or low (<20% inhibition) anti-E. coli activity. The V6 region of the 16S ribosomal RNA gene was amplified and sequenced using the Illumina HiSeq 2000 platform. Filtered culture supernatants from Lactobacillus crispatus, Lactobacillus iners, and Gardnerella vaginalis were also assayed for E. coli inhibitory activity. RESULTS: Sixteen samples (10 with high and 6 with low activity) yielded evaluable microbiome data. There was no difference in the predominant microbiome species in pregnant compared to non-pregnant women (n = 8 each). However, there were significant differences between women with high compared to low E. coli inhibitory activity. High activity was associated with a predominance of L. crispatus (p<0.007) and culture supernatants from L. crispatus exhibited greater E. coli inhibitory activity compared to supernatants obtained from L. iners or G. vaginalis. Notably, the E. coli inhibitory activity varied among different strains of L. crispatus. CONCLUSION: Microbiome communities with abundant L. crispatus likely contribute to the E. coli inhibitory activity of vaginal secretions and efforts to promote this environment may prevent E. coli colonization and related sequelae including preterm birth.

Genital tract HIV RNA levels and their associations with human papillomavirus infection and risk of cervical precancer.

OBJECTIVE: Plasma HIV RNA levels have been associated with the risk of human papillomavirus (HPV) and cervical neoplasia in HIV-seropositive women. However, little is known regarding local genital tract HIV RNA levels and their relation with cervical HPV and neoplasia. DESIGN/METHODS: In an HIV-seropositive women's cohort with semiannual follow-up, we conducted a nested case-control study of genital tract HIV RNA levels and their relation with incident high-grade squamous intraepithelial lesions (HSIL) subclassified as severe (severe HSIL), as provided for under the Bethesda 2001 classification system. Specifically, 66 incidents of severe HSIL were matched to 130 controls by age, CD4 count, highly active antiretroviral therapy use, and other factors. We also studied HPV prevalence, incident detection, and persistence in a random sample of 250 subjects. RESULTS: Risk of severe HSIL was associated with genital tract HIV RNA levels (odds ratio comparing HIV RNA ≥ the median among women with detectable levels versus undetectable, 2.96; 95% confidence interval: 0.99 to 8.84; Ptrend = 0.03). However, this association became nonsignificant (Ptrend = 0.51) after adjustment for plasma HIV RNA levels. There was also no association between genital tract HIV RNA levels and the prevalence of any HPV or oncogenic HPV. However, the incident detection of any HPV (Ptrend = 0.02) and persistence of oncogenic HPV (Ptrend = 0.04) were associated with genital tract HIV RNA levels, after controlling plasma HIV RNA levels. CONCLUSIONS: These prospective data suggest that genital tract HIV RNA levels are not a significant independent risk factor for cervical precancer in HIV-seropositive women, but they leave open the possibility that they may modestly influence HPV infection, an early stage of cervical tumorigenesis.
