Key Points: Question: Among patients with increased risk of postpartum venous thromboembolism, does a more selective protocol for initiating postpartum enoxaparin, compared with a standard risk-stratified protocol, decrease wound complications without increasing patient risk of venous thromboembolism? Findings: In this retrospective observational study, a more selective protocol for chemoprophylaxis resulted in a decrease in heparin (enoxaparin) administration (16% vs 8%). The selective protocol for postpartum enoxaparin was associated with a decrease in wound hematoma (0.7% vs 0.3% in the selective protocol group; adjusted odds ratio, 0.38; 95% CI, 0.21-0.67) without evidence of increase in venous thromboembolism (0.1% vs 0.1% in the selective protocol group; adjusted odds ratio, 0.40; 95% CI, 0.12-1.36). Meaning: A more selective protocol for postpartum enoxaparin was associated with decreased rates of wound hematomas without evidence of increased rates of postpartum thromboembolic events. Importance: In 2016, our institution adopted a pregnancy-related venous thromboembolism (VTE) prophylaxis protocol based on American College of Obstetricians and Gynecologists guidelines that recommended postpartum heparin-based chemoprophylaxis (enoxaparin) based on a risk-stratified algorithm. In response to increased wound hematomas without significant reduction in VTE using this protocol, a more selective risk-stratified approach was adopted in 2021. Objective: To evaluate outcomes of the more selective risk-stratified approach to heparin-based obstetric thromboprophylaxis (enoxaparin) protocol. Design, Setting, and Participants: Retrospective observational study of 17 489 patients who delivered at a single tertiary care center in the southeast US between January 1, 2016, and December 31, 2018 (original protocol), and between December 1, 2021, and May 31, 2023 (more selective protocol). Patients receiving outpatient anticoagulation for active VTE or high VTE risk during pregnancy were excluded. Exposure: Standard risk-stratified and more selective postpartum VTE chemoprophylaxis protocols. Main Outcomes and Measures: The primary outcome was clinical diagnosis of wound hematoma up to 6 weeks pos tpartum. The secondary outcome was new diagnosis of VTE up to 6 weeks post partum. We compared baseline characteristics and outcomes between groups and estimated adjusted odds ratios with 95% CIs of primary and secondary outcomes using the original protocol group as reference. Results: Of 17 489 patients included in the analysis, 12 430 (71%) were in the original protocol group and 5029 (29%) were in the more selective group. Rates of chemoprophylaxis decreased from 16% (original protocol) to 8% (more selective protocol). Patients in the more selective group were more likely to be older, be married, and have obesity or other comorbidities (hypertension, diabetes, cardiac disease). Compared with the original protocol, the more selective protocol was associated with a decrease in any wound hematoma (0.7% vs 0.3%; adjusted odds ratio [aOR], 0.38; 95% CI, 0.21-0.67), specifically due to a lower rate of superficial wound hematomas (0.6% vs 0.3%; aOR, 0.43; 95% CI, 0.24-0.75). There was no significant increase in VTE or individual types of VTE (0.1% vs 0.1%; aOR, 0.40; 95% CI, 0.12-1.36). Conclusions and Relevance: A more selective risk-stratified approach to an enoxaparin thromboprophylaxis protocol for VTE was associated with decreased rates of wound hematomas without increased rates of postpartum VTE. This observational study assesses incidence of wound hematoma diagnoses up to 6 weeks post partum among obstetric patients who received thromboprophylaxis according to less selective vs more selective hospital chemoprophylaxis protocols.

Objective The aim of the study is to evaluate the association between the amount of proteinuria at the time of diagnosis of preeclampsia with severe features (severe preeclampsia [SPE]) and duration of expectant management (EM) and other perinatal outcomes. Study Design This is a retrospective cohort study of patients with SPE delivering live, non-anomalous singletons at 23 0/7 to 34 2/7 weeks' estimated gestational age (EGA) at a single tertiary center 2016 to 2018. Patients with proteinuria assessment (24-hour total urine protein or urine protein-to-creatinine ratio extrapolation) within 3 days of SPE diagnosis were included. Patients delivered for an indication other than SPE were excluded. Patients were categorized by amount of proteinuria (mg): none (≤300), mild (301–1,000), moderate (1,001–3,000), and massive (≥3,001). The primary outcome was the proportion of potential EM time achieved (%EM), i.e., days of EM divided by days from SPE diagnosis to 34 weeks. Secondary outcomes included delivery EGA, days of EM, and perinatal outcomes. Bivariable and multivariable analyses compared outcomes across groups. Results Of 295 patients included, 21% had no proteinuria, 33% mild, 19% moderate, and 27% massive. Groups differed by EGA at diagnosis, age, parity, chronic hypertension, and renal disease. %EM was not significantly different between groups (adjusted β coefficient 4.1 [95% CI −5.3, 13.5] for mild proteinuria vs. none, −4.1 [95% CI −14.9, 6.6] for moderate proteinuria vs. none, and −5.6 [95% CI −16.0, 4.7] for massive proteinuria vs. none). Increasing proteinuria was associated with earlier delivery EGA but only days of EM in the mild versus no proteinuria groups. There was no significant association between proteinuria and maternal composite morbidity, but patients with mild and massive proteinuria had higher odds of neonatal composite morbidities compared with no proteinuria. Conclusion Among patients with SPE, proteinuria level was not consistently associated with duration of EM. However, patients with the greatest amounts of proteinuria may have worse neonatal and selected maternal outcomes. Key Points Amount of proteinuria was not associated with the duration of expectant management. Greater proteinuria was associated with earlier delivery in severe preeclampsia. Massive proteinuria in preeclampsia was associated with select adverse maternal and neonatal outcomes. [ABSTRACT FROM AUTHOR]

Objective The aim of the study is to evaluate the use of a bipolar electrocautery device for complete salpingectomy at cesarean to improve procedure completion rates, operative time, and surgeon reported satisfaction as compared with standard bilateral tubal ligation (BTL) and suture-cut-tie salpingectomy. Study Design This is a prospective cohort study of women undergoing planned, non-emergent cesarean with desired sterilization with complete salpingectomy utilizing a bipolar electrocautery device. Study patients were compared with historic controls from a randomized controlled trial (RCT) of complete salpingectomy via suture-cut-tie method versus BTL conducted at our institution (SCORE trial, NCT02374827). Outcomes were compared with groups from the original RCT. Results Thirty-nine women were consecutively enrolled (12/2018–11/2019) into the device arm of the study and compared with the original SCORE cohort (n = 40 BTL, n = 40 salpingectomy without a device). Salpingectomy performance with the bipolar electrocautery device was successfully completed in 100% (39/39) of enrolled women, with one device failure requiring the use of a second device, as compared with 95% (38/40) in the BTL (p = 0.49) and 67.5% (27/40) in salpingectomies without a device (p < 0.001). Mean operative time of sterilization procedure alone demonstrated device use as having the shortest operative time of all (device salpingectomy 5.0 ± 3.6 vs. no device 18.5 ± 8.3 minutes, p < 0.001; and vs. BTL 6.9 ± 5.0, p = 0.032). Mean sterilization procedure endoscopic band ligation (EBL) was demonstrated to be significantly different between each group, least amongst BTL followed by device (6.3 ± 4.8 vs. 8.4 ± 24.8, p < 0.001), and most by suture-cut-tie method (17.7 ± 14.3, p < 0.001 compared with device). Surgeon reported attitudes of complete salpingectomy performance in general practice outside an academic setting was greater with a device than without (79.5 vs. 35.3%; p < 0.001). Conclusion Use of a bipolar electrocautery device improved operative times and surgeon satisfaction for salpingectomy at cesarean over standard suture ligation. Device use improved surgeon reported outcomes and may improve incorporation of complete salpingectomy at cesarean. Key Points Electrocautery bipolar device use was safe at the time of salpingectomy during cesarean. Greater surgeon satisfaction occurs using a device than without. Decreased surgical time with device use is seen making the procedure equal to BTL. [ABSTRACT FROM AUTHOR]
