Incidence and risk factors for venous thromboembolism events after different routes of pelvic organ prolapse repairs.
Venous thromboembolism events, including deep venous thrombosis and pulmonary embolism are the most common cause of preventable deaths in hospitalized patients in the United States. Although the risk of venous thromboembolism events in benign gynecologic surgery is generally low, the potential for venous thromboembolism events in urogynecologic population is significant because most patients undergoing the pelvic organ prolapse surgery have increased surgical risk factors. ⋯ The overall incidence of venous thromboembolism after pelvic organ prolapse repairs based on a recent, large cohort database was very low, confirming the finding in previous smaller cohort studies. The highest venous thromboembolism risk was associated with abdominal route, and more than 60% of venous thromboembolism events occurred within 10 days after surgery. Thus, focus should be placed on risk-reducing strategies in the immediate postoperative period, with greater emphasis on patients undergoing abdominal surgery.

Fragmentation of care, wherein a patient is readmitted to a hospital different from the initial point of care, has been shown to be associated with worse patient outcomes in other medical specialties. However, postpartum fragmentation of care has not been well characterized in obstetrics. ⋯ This study of nationwide estimates of postpartum fragmentation found discontinuity of postpartum care was associated with increased risk for severe morbidity, high costs, and long length of stay. Reduction of fragmentation may represent an important goal in overall efforts to improve postpartum care.

Practice GuidelineSociety for Maternal-Fetal Medicine Consult Series #51: Thromboembolism prophylaxis for cesarean delivery.
Venous thromboembolism is a major cause of maternal morbidity and mortality. The risk of venous thromboembolism is particularly elevated during the postpartum period and especially after cesarean delivery. ⋯ This Consult discusses the different guidelines on prophylaxis of venous thromboembolism after cesarean delivery and provides recommendations based on the available evidence. The recommendations by the Society for Maternal-Fetal Medicine are as follows: (1) we recommend that all women who undergo cesarean delivery receive sequential compression devices starting before surgery and that the compression devices be used continuously until the patient is fully ambulatory (GRADE 1C); (2) we suggest that women with a previous personal history of deep venous thrombosis or pulmonary embolism who undergo cesarean delivery receive both mechanical (starting preoperatively and continuing until ambulatory) and pharmacologic (for 6 weeks postoperatively) prophylaxis (GRADE 2C); (3) we suggest that women with a personal history of an inherited thrombophilia (high-risk or low-risk) but no previous thrombosis who undergo cesarean delivery receive both mechanical (starting preoperatively and continuing until ambulatory) and pharmacologic (for 6 weeks postoperatively) prophylaxis (GRADE 2C); (4) we recommend the use of low-molecular-weight heparin as the preferred thromboprophylactic agent in pregnancy and the postpartum period (GRADE 1C); (5) when pharmacologic thromboprophylaxis is needed in pregnant women with class III obesity, we suggest the use of intermediate doses of enoxaparin (GRADE 2C); and (6) we recommend that each institution develop a patient safety bundle with an institutional protocol for venous thromboembolism prophylaxis among women who undergo cesarean delivery (Best Practice).

Time trends in placenta-mediated pregnancy complications after assisted reproductive technology in the Nordic countries.
The use of assisted reproductive technology is increasing worldwide and conception after assisted reproduction currently comprises 3%-6% of birth cohorts in the Nordic countries. The risk of placenta-mediated pregnancy complications is greater after assisted reproductive technology compared with spontaneously conceived pregnancies. Whether the excess risk of placenta-mediated pregnancy complications in pregnancies following assisted reproduction has changed over time, is unknown. ⋯ The risk of placenta-mediated pregnancy complications following assisted reproductive technology remains higher compared to spontaneously conceived pregnancies, despite declining rates of multiple pregnancies. For hypertensive disorders in pregnancy and placental abruption, pregnancies after assisted reproduction follow the same time trends as the background population, whereas for placenta previa, risk has increased over time in pregnancies after assisted reproductive technology.

Neonatal mortality in the United States is related to location of birth (hospital versus home) rather than the type of birth attendant.
Planned home births have leveled off in the United States in recent years after a significant rise starting in the mid-2000s. Planned home births in the United States are associated with increased patient-risk profiles. Multiple studies concluded that, compared with hospital births, absolute and relative risks of perinatal mortality and morbidity in US planned home births are significantly increased. ⋯ The safety of birth in the United States varies by location and attendant. Compared with US hospital births attended by a certified nurse-midwife, planned US home births for all types of attendants are a less safe setting of birth, especially when recognized risk factors are taken into account. The type of midwife attending US planned home birth appears to have no differential effect on decreasing the absolute and relative risk of neonatal mortality of planned home birth, because the difference in outcomes of US planned home births attended by direct-entry midwives or by certified nurse-midwives is not statistically significant.
