Practice patterns and preferences of obstetricians and gynecologists regarding thromboprophylaxis at the time of Cesarean section

OBJECTIVE: Our survey aimed to identify knowledge and application of guidelines in the United States by assessing practicing obstetricians and gynecologists (OBGYN) use of thromboprophylaxis, preferred methods and whether their type of practice influenced their choices. STUDY DESIGN: A cross-sectional survey of fellows of the American College of Obstetricians and Gynecologists (ACOG) was performed. A 21-item paper and electronic questionnaire was sent to each participant. A total of three mailings were carried out. RESULTS: In total, 400 OBGYN were invited to participate. Questionnaires were returned by 209 (52.3%), 157 (75.1%) of whom provided prenatal care within the last year. All respondents used at least one method of thromboprophylaxis routinely. About 92.4% used pneumatic compression devices. An equal proportion used unfractionated heparin and low molecular weight heparin routinely (17.8%). About 19.1% routinely used combination prophylaxis. In total, 77.1% (n = 121) used the ACOG guidelines. Local hospital guidelines were referenced by 38.2% (n = 60). Other guidelines referenced were the ACCP guideline (n = 34, 21.7%) and several international guidelines (n = 5, 3.3%). CONCLUSION: Awareness of the risk of thromboembolism around delivery by cesarean section is high among OBGYN practitioners. Broadening guidelines to encompass all deliveries, not only cesareans, with a focus on identifying the patient at risk, would likely be successful.
