Patient experience and decision-making process for laser photocoagulation for monochorionic twin pregnancy: A qualitative exploration.

INTRODUCTION: To explore patients' perspectives on diagnosis and treatment options for complicated monochorionic multiple gestations, and experiences with fetoscopic laser photocoagulation. METHODS: This is a prospective cohort study of patients undergoing laser photocoagulation. Participants were interviewed during pregnancy and the postpartum period. Qualitative analysis was performed. RESULT: 27 patients who were candidates for laser photocoagulation were included. All elected to have laser photocoagulation. Patients chose surgery with goals of improving survival, decreasing the risk of preterm delivery, and improving the long-term health of their fetuses. They demonstrated accurate knowledge of the risks and benefits of treatment. Most (74%) felt that laser photocoagulation represented their only viable clinical option. Few seriously considered pregnancy termination or selective reduction (7% and 11% respectively). Postpartum, patients expressed no regrets about their decisions for surgery, but many felt unprepared for the challenges of preterm delivery. CONCLUSION: Participants weighed treatment options similarly to fetal specialists. They acknowledged but did not seriously consider treatments other than fetoscopic laser photocoagulation, and were highly motivated to do whatever they could to improve outcomes for their fetuses.

Association of Peripartum Lactate Levels With Infection Outcomes.

OBJECTIVE: To determine whether lactate levels were associated with maternal infection and infection-related outcomes in the antepartum, intrapartum, and early postpartum periods. DESIGN: Retrospective, observational cohort. SETTING: Eleven hospitals from a single health system. PARTICIPANTS: Women (N = 783) with at least one lactate and blood culture test for obstetric sepsis screening in the antepartum period (n = 154), intrapartum period (n = 348), and early postpartum period (n = 281) from January 2, 2018, to October 21, 2020. METHODS: We reported the proportion of participants with adverse outcomes by lactate cut points (≤2.0 and >2.0 mmol/L). We used logistic regression to model the association of infection-related outcomes with lactate levels and calculated receiver operating characteristic curves. RESULTS: Lactate was associated with bacteremia among participants in the antepartum period (odds ratio [OR] = 1.60, 95% confidence interval [CI] [1.00, 2.56]) but not among participants in the intrapartum and early postpartum periods. Higher lactate levels were significantly associated with a composite measure of infection-related outcomes (OR = 1.41, 95% CI [1.14, 1.81]), with no differential association by antepartum, intrapartum, or early postpartum periods. Lactate levels were positively associated with intraamniotic infection in the antepartum period (OR = 1.57, 95% CI [1.06, 1.81]) but not in the intrapartum period. The receiver operating characteristic curve indicated that the lactate threshold of 2.0 mmol/L has poor sensitivity. Overall, participants in the antepartum period had lower lactate values than participants in the intrapartum and early postpartum periods. CONCLUSION: Lactate levels were not consistently associated with infection-related measures across all periods. We suggest caution when interpreting lactate levels when sepsis is suspected.

The Use of Saliva Samples to Test for Congenital Cytomegalovirus Infection in Newborns: Examination of False-Positive Samples Associated with Donor Milk Use.

A universal screening research study was conducted in six hospitals to identify the clinical sensitivity of polymerase chain reaction (PCR) testing on newborn dried blood spots (DBSs) versus saliva specimens for the diagnosis of congenital cytomegalovirus (cCMV). CMV DNA positive results from DBSs or saliva were confirmed with urine testing. Findings of several false-positive (FP) saliva PCR results prompted an examination of a possible association with donor milk. Documentation of the frequency of positive saliva results, including both true-positive (TP) and FP status from clinical confirmation, occurred. The frequency of donor milk use was compared for TP and FP cases. Of 22,079 participants tested between 2016 and 2022, 96 had positive saliva results, 15 were determined to be FP, 79 TP, and 2 were excluded for incomplete clinical evaluation. Newborn donor milk use was identified for 18 (19.14%) of all the positive saliva screens. Among the 15 FPs, 11 (73.33%) consumed donor milk compared to 7 of the 79 TPs (8.8%) (OR 28.29, 95% CI 7.10-112.73, p < 0.001). While milk bank Holder pasteurization inactivates CMV infectivity, CMV DNA may still be detectable. Due to this possible association, screening programs that undertake testing saliva for CMV DNA may benefit from documenting donor milk use as a potential increased risk for FP results.

Implementation and Outcomes of a Model of Care for Placenta Accreta Spectrum in a Community-Based Private Practice.

OBJECTIVE: The aim of the study is to describe a model of care and outcomes for placenta accreta spectrum (PAS) implemented in the context of a community based non-academic health system. STUDY DESIGN: The program for management of PAS includes a multidisciplinary team approach with protocols for ultrasound assessment, diagnosis, and surgery. The program was implemented in the two largest private hospitals in the Twin Cities, Minnesota, United States. Maternal and fetal outcomes as well as cost were compared for histopathologic confirmed PAS cases before (2007-2014, n = 41) and after (2015-2017, n = 26) implementation of the PAS program. RESULTS: Implementation of the PAS program was associated with ICU admission reductions from 53.7 to 19.2%, p = 0.005; a decrease of 1,682 mL in mean estimated blood loss (EBL) (p = 0.061); a decrease in transfusion from 85.4 to 53.9% (p = 0.005). The PAS program also resulted in a (non-significant) decrease in both surgical complications from 48.8 to 38.5% (p = 0.408) and postoperative complications from 61.0 to 42.3% (p = 0.135). The total cost of care for PAS cases in the 3 years after implementation of the program decreased by 33%. CONCLUSION: The implementation of a model of care for PAS led by a perinatology practice at a large regional non-academic referral center resulted in reductions of ICU admissions, operating time, transfusion, selected surgical complications, overall postoperative complications, and cost. KEY POINTS: · Implementation of a PAS care model resulted in reduced ICU admissions from 53.7% to 19.2%.. · Patient safety increased by reducing blood loss, transfusions and postoperative complications.. · This model decreased operating time, as well as total cost of care by 33%..

Maternal and Neonatal Outcomes in Hospital-Based Deliveries With Water Immersion.

OBJECTIVE: To compare neonatal intensive care unit (NICU) or special care nursery admission for deliveries with water immersion compared with deliveries in the matched control group without water immersion. Secondary outcomes included adverse neonatal diagnoses, maternal infections, and perineal lacerations. METHODS: We conducted a retrospective study using electronic health record data (2014-2018) from two health systems (eight hospitals), with similar clinical eligibility, associated with low risks of intrapartum complications, and implementation policies for waterbirth. The water immersion group included women intending waterbirth. Water immersion was recorded prospectively during delivery. The comparison population were women who met the clinical eligibility criteria for waterbirth but did not experience water immersion during labor. Comparison cases were matched (1:1) using propensity scores. Outcomes were compared using Fischer's exact tests and logistic regression with stratification by stage of water immersion. RESULTS: Of the 583 women with water immersion, 34.1% (199) experienced first-stage water immersion only, 65.9% (384) experienced second-stage immersion, of whom 12.0% (70) exited during second stage, and 53.9% (314) completed delivery in the water. Neonatal intensive care unit or special care nursery admissions were lower for second-stage water immersion deliveries than deliveries in the control group (odds ratio [OR] 0.3, 95% CI 0.2-0.7). Lacerations were lower in the second-stage immersion group (OR 0.5, 95% CI 0.4-0.7). Neonatal intensive care unit or special care nursery admissions and lacerations were not different between the first-stage immersion group and their matched comparisons. Cord avulsions occurred for 0.8% of second-stage water immersion deliveries compared with none in the control groups. Five-minute Apgar score (less than 7), maternal infections, and other adverse outcomes were not significantly different between either the first- or second-stage water immersion groups and their control group. CONCLUSION: Hospital-based deliveries with second-stage water immersion had lower risk of NICU or special care nursery admission and perineal lacerations than matched deliveries in the control group without water immersion.

The effect of placental location in cases of placenta accreta spectrum.

BACKGROUND: Placenta accreta spectrum affects approximately 3 in 1000 pregnancies. There is a paucity of data evaluating the effect of placental location on diagnosis, risk factors, and resultant outcomes in cases of placenta accreta spectrum. OBJECTIVE: We analyzed placenta accreta spectrum cases to assess whether risk factors or maternal outcomes varied based on placental location. MATERIALS AND METHODS: We performed a retrospective chart review of pathology-confirmed cases of placenta accreta spectrum from patients delivering at 2 large urban hospitals in the same healthcare system from 2007 to 2017. Placental location was defined by ultrasound images and confirmed by pathology reports. Location was categorized as anterior, posterior, or anterior/posterior for those with placental location at both sites. Fisher exact tests and analysis of variance were used to examine associations with measures of diagnosis, risk factors, and maternal outcomes. RESULTS: A total of 86 pathology-confirmed placenta accreta spectrum cases were reviewed. The distribution of placental location on ultrasound was as follows: 19% posterior, 59% anterior, and 22% anterior/posterior. We found that prior cesarean delivery was lower with posterior placenta accreta spectrum (63% vs 94% vs 84% in the anterior and anterior/posterior groups respectively; (P = .007); however, in vitro fertilization rates were significantly higher (38% vs 2% vs 5% in the anterior and anterior/posterior groups respectively; P = .001). There was also lower incidence of percreta with posterior placenta accreta spectrum compared to the anterior and anterior/posterior groups (19% vs 47% vs 58% respectively; P = .055). Posterior cases were less likely to have placenta accreta spectrum suspected prenatally (50%) compared to anterior (80%) and anterior/posterior (89%) cases (P = .019). Despite late diagnosis, ureteral injury was the only surgical complication that was more common in patients with posterior placenta accreta spectrum (13% vs 0% vs 5% for anterior and anterior/posterior groups respectively; P = .037). CONCLUSION: Placenta accreta spectrum with posterior placental location is associated with delayed diagnosis, surgical complications, assisted reproductive technology, and lower numbers of prior cesarean deliveries relative to anterior location. These differences in outcomes and risk factors based on placental location may allow for heightened clinical awareness, and improved diagnosis and management.

Who Gives Birth in the Water? A Retrospective Cohort Study of Intended versus Completed Waterbirths.

INTRODUCTION: Most waterbirth studies have been conducted outside the United States with a primary focus on birth outcomes. Studies to date provide limited information about how often women choosing waterbirth end water immersion before the birth and about the reasons for tub exit. This study examines a cohort of women intending a hospital-based waterbirth and documents the timing and reasons for tub exit. Demographic, clinical, and intrapartum care provider characteristics among women completing waterbirth were compared with those who exited the water prior to birth. METHODS: This is a collaborative, multisite study from 2 health systems (8 hospitals) using retrospective electronic health records from August 2014 through December 2017. RESULTS: Of 576 women who entered the waterbirth tub, 48% exited prior to the birth. The primary reasons for exit were maternal choice (50%), medical indication (32%), and provider decision (13%). Women exiting in the first stage did so primarily by choice (57%), whereas medical indication (42%) was the most common reason among women exiting in the second stage. Women who completed waterbirth did not differ from those who exited prior to birth with regard to age, race, ethnicity, country of origin, language, marital status, or intrapartum care provider specialty. Women completing waterbirth were more likely to have previously given birth (72% vs 47%) and to have a provider with more water immersion births during the study period (65% vs 55%). DISCUSSION: Giving birth in the tub was associated with parity and intrapartum care provider experience. Half of the women intending waterbirth in this study exited the tub, with variation in exit reason by stage and provider type. It is important for women to understand that they or their provider may change the birth plan based on labor progress and maternal experience.
