A SWIFT Method for Handing Off Obstetrical Patients on the Labor Floor.

OBJECTIVE: The aim of this study was to improve patient handoffs on the labor floor. METHODS: A prospective cohort study of obstetrics residents at Montefiore Medical Center was performed between 2012 and 2014. Labor-floor handoffs were recorded before and after didactic sessions as well as after installation of whiteboards formatted with the mnemonic SWIFT (Subject, Why?, Issues, Fetus, Tasks). Handoff transcripts were evaluated by obstetricians blinded to timing and speaker identity. An intraclass correlation coefficient accounted for evaluator differences. Data analysis was by ordinal logistic regression, the generalized estimating equations method (correlated data), and Bonferroni adjustment (multiple comparisons). RESULTS: Forty-five handoffs were evaluated (15 each predidactics, postdidactics, and postwhiteboard revision). Higher completeness scores over time were noted for admission reason, labor concerns, and task list (not statistically significant). Comprehensive score increases prelecture to postwhiteboard were seen in handoff clarity (2.81 versus 2.91) and overall quality (2.77 versus 2.81) (not statistically significant). A subanalysis of four residents who gave multiple handoffs over different periods revealed few significant changes over time. Greater interevaluator consistency was noted with more objective elements. CONCLUSIONS: The mnemonic SWIFT, with formalized curricula for obstetrical resident training focusing on new learners and increased faculty involvement and reinforcement, may result in improvement of handoffs on the labor floor.

Vitamin A and ß-carotene in pregnant and breastfeeding post-bariatric women in an urban population.

Background As breastfeeding awareness and social acceptance are increased, maternal nutritional deficiency requires more investigation. Methods A prospective cohort study was conducted to determine if vitamin A deficiency is more common in pregnant, lactating post-bariatric surgery women in an inner city population. Antepartum, women after bariatric surgery and controls with no history of malabsorption were recruited. Third trimester, postpartum maternal blood and cord blood were collected as well as three breast milk samples: colostrum, transitional and mature milk. A nutritional survey of diet was completed. Each serum sample was analyzed for total retinol and ß-carotene; breast milk samples were analyzed for retinol and retinyl esters, total retinol and ß-carotene. Results Fifty-three women after bariatric surgery and 66 controls were recruited. Postpartum serum retinol was significantly higher in women after bariatric surgery in the univariate analysis (P<0.0001) and confirmed in the multiple linear mixed model (P=0.0001). Breast milk colostrum retinol and transitional milk total retinol were significantly greater in the bariatric surgery group in the univariate analysis (P=0.03 and P=0.02, respectively), but not after adjusting for confounders. Serum ß-carotene in the third trimester and postpartum were lower (P<0.0001 and P=0.003, respectively) in the bariatric surgery group but not after adjusting for confounders. Vitamin A deficiency was high in both groups in serum and breast milk samples. Conclusion Nutritional deficiencies in breastfeeding women after bariatric surgeries may in fact be less common than in control women in an inner city.

Induction of labor using one dose vs multiple doses of misoprostol: a randomized controlled trial.

BACKGROUND: Misoprostol is a common agent that is used to ripen the cervix and induce labor, yet there is no clear evidence of the optimal number of doses needed to achieve a higher rate of vaginal delivery. OBJECTIVE: Our primary objective was to compare the rate of vaginal delivery within 24 hours between a 1-dose and a multiple-dose regimen of misoprostol for the induction of labor. STUDY DESIGN: A randomized controlled trial was conducted from March 2016 to March 2017 that compared a single dose to up to 4 doses of misoprostol. Randomization was stratified by parity. Women with a singleton pregnancy ≥37 weeks gestation with intact membranes who had been admitted for labor induction with a Bishop score ≤6 were included. Our primary outcome was the rate of vaginal delivery within 24 hours. Secondary outcomes included time to vaginal delivery, cesarean delivery rate, and maternal and neonatal morbidity. Based on a power of 80%, an alpha of .05, and the assumption that 50% of women in the multiple-misoprostol group would deliver vaginally in 24 hours, a sample size of 220 patients was needed to detect a 20% increase in vaginal delivery rate within 24 hours in the 1-misoprostol group. Continuous variables were compared with the use of the Mann-Whitney test. Categoric variables were compared with the use of the Fisher's exact test. Probability values <.05 were considered statistically significant. RESULTS: Two hundred fifty women were assigned randomly. Demographics and clinical characteristics were similar between groups. In the univariate analysis, there was no difference in the rate of vaginal delivery within 24 hours between the 1-misoprostol group and the multiple-dose group (41.7% vs 44.7%, respectively; P=.698) or time to vaginal delivery (1187 min vs 1321 min, respectively; P=.202). The 1-misoprostol group had a greater cesarean delivery rate (35.8% vs 22.8%; P=.034). In a Poisson regression that controlled for Bishop score before the initiation of oxytocin, parity, gestational age, body mass index, estimated fetal weight, artificial rupture of membrane at <6 cm, and Foley balloon placement, the treatment group was no longer associated with cesarean delivery rate. Instead, a Bishop score of <4 before the initiation of oxytocin and nulliparity were associated significantly with cesarean delivery rate. CONCLUSION: In this first randomized controlled trial in the literature to compare a single with a multiple dosing of misoprostol, we found that the 1-dose regimen is an acceptable alternative for the induction for labor, especially for multiparous women and for patients with a Bishop score >4 after the first dose.

Performance of Low-Dose Perfusion Scintigraphy and CT Pulmonary Angiography for Pulmonary Embolism in Pregnancy.

BACKGROUND: The symptoms of normal pregnancy overlap those of pulmonary embolism (PE). Limited literature suggests that low-dose perfusion scanning (LDQ), which yields lower maternal-fetal radiation exposure than CT pulmonary angiography (CTPA), performs well in excluding PE in pregnant patients. METHODS: We performed a retrospective cohort study of sequential pregnant women who underwent imaging for PE with LDQ or CTPA between 2008 and 2013 at Montefiore Medical Center. Our practice recommends LDQ for patients with negative results on chest radiographs. Patients were categorized according to initial imaging modality, and a subgroup analysis was performed in patients with asthma. The primary outcome was the negative predictive value (NPV) of imaging determined by VTE diagnosis within 90 days. RESULTS: Of 322 pregnant women (mean age, 27.3 ± 6.3 years), initial imaging was positive for PE in 2.7% (6 of 225) of LDQs and 4.1% (4 of 97) of CTPAs, negative in 88.0% (198 of 225) of LDQs and 86.6% (84 of 97) of CTPAs, and indeterminate/nondiagnostic in 9.3% (21 of 225) of LDQs and 9.3% (9 of 97) of CTPAs (P = .79). Ten patients (3.1%) were treated for PE. The NPV was 100% for LDQ and 97.5% for CTPA. Subgroup analysis of patients with asthma (23.9% of this population) revealed a high likelihood of a negative study in the LDQ and CTPA groups (74.1% and 87.0%, respectively) and 100% NPV for both modalities. CONCLUSIONS: PE is an uncommon diagnosis in pregnancy. LDQ and CTPA perform well, with less maternal-fetal radiation exposure with LDQ. Therefore, when available, LDQ is a reasonable first-choice modality for suspected PE in pregnant women with a negative result on chest radiograph.
